A monitor for an electric arc welder as the welder performs a selected arc welding process by creating actual welding parameters, such as arc current and arc voltage, between an advancing welding wire and a workpiece, where the process involves an arc and is defined by a series of rapidly repeating wave shapes constituting a weld cycle with a cycle time, the wave shapes are each segmented into time states having command signals corresponding to the actual parameters and a time duration. The monitor selects a specific wave shape state, reads one of the actual parameters, compares the actual read parameter with a function of the command signal corresponding to the actual parameter, and uses-the comparison to generate a characteristic of the welding process during the selected state.

The invention comprises lipid derivatives that rapidly degrade in the pH range from 4.0 to 7.0 and lipidic delivery systems that contain them. These lipid derivatives can be used to modify the delivery properties of the lipidic delivery systems to enable prolonged circulation times or more rapid drug unloading in the target tissue. The lipid derivatives are amphipathic compounds comprising a hydrophilic head group joined to a hydrophobic group by an acid-labile ortho ester linkage. The delivery systems of the invention exhibit degradation of less than 10% within 3 hours at a pH of 7.4 and degradation greater than 50% within 60 min at a pH of 5.0.

Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.

The system sealingly separates the air flow from the breast milk and uses a single air tube for both positive pressure and negative pressure to be applied to a woman's breast. The breast pump can have a piston/cylinder device for generating pressure that allows a user to control suction and cycle time.

Hydrophobic drugs become more practical for treatments by being encapsulated in micelle compositions for increasing solubility. Micelle compositions may include an excipient tocopherol and/or prodrug formulations of the drug. Micelles extend the time period the drug remains in the micelles to improve drug circulation time and thereby drug delivery. Hydrophobic drugs for micelle encapsulation may include rapamycin, geldanamycin, and paclitaxel. Administration of these micelle compositions does not require Cremophor EL or Tween 80, avoiding serious side effects associated with these products which would previously accompany such drug administration.

The present invention is directed to a method and system for identifying, quantifying and presenting to a user constraints in an automated manufacturing or processing facility. A data processing system continuously receives basic status signals and state signals from automation equipment in the facility and evaluates and processes these signals to derive a throughput capability measure (a measure of constraint) of each given manufacturing workstation in the process. The throughput capability measure is expressed as a ratio of an ideal cycle time to an accumulated overcycled time. The accumulated overcycled time includes only delays and excludes any speed-up of a workstation. A constraint is identified as the workstation that has the lowest throughput capability measure as compared with all other workstations in a production line. Preferably, throughput capability measures for all workstations are presented to users graphically. Further drill-down can be provided for obtaining more detailed information about the constraint and capacity loss as well as entering information relevant to the constraint, such as a stoppage or slow-down.

An energy efficient oxygen concentrator in which a compressor applies pressurized air to at least two gas separating elements which will pass a flow of oxygen while blocking a flow of nitrogen. The gas separating elements are alternately cycled between a gas separating mode for producing oxygen enriched gas and a purge mode for purging nitrogen from the elements. According to the invention, the speed of the cycle time is increased as the oxygen enriched gas flow requirement is decreased below the maximum concentrator output. The higher cycle speed reduces the maximum compressor pressure to reduce energy consumption.

A memory interface system and method are provided for transferring data between a memory controller and an array of storage elements. The storage elements are preferably SRAM elements, and the memory interface is preferably one having separate address bus paths and separate data bus paths. One address bus path is reserved for receiving read addresses and the other address bus path is reserved for receiving write addresses. One of the data bus paths is reserved for receiving read data from the array, and the other data bus path is reserved for receiving data written to the array. While bifurcating the address and data bus paths within the interface is transparent to the memory controller, the separate paths afford addressing phases of a read and write address operation to be partially overlapped, as well as the data transfer phases. This will essentially reduce the cycle time between a read and write memory access, and proves useful when maximizing the data throughput across the data bus when implementing double data rate (QDR) mechanisms.

A technique for optimizing cycle time in maintaining cache coherency. Specifically, a method and apparatus are provided to optimize the processing of requests in a multi-processor-bus system which implements a snoop-based coherency scheme. The acts of snooping a bus for a first address and searching a posting queue for the next address to be snooped are performed simultaneously to minimize the request cycle time.

A programmable thermostat time/temperature display has a continuous loop timeline with a plurality of temperature transition points along the timeline to define a plurality of timeline segments. Temperature and time IDs are displayable on the display and are associated with at least some of the timeline segments and temperature transition points. A thermostat can be programmed by touching a position on a touchscreen associated with a temperature transition point on a continuous loop timeline on the touchscreen. The touching step may be carried out by moving the first temperature transition point from a first position along the timeline to a second position along the timeline so to change the first timeline segment. An updated time ID may be selected for the first temperature transition point.

The present invention relates to novel energy efficient sorption processes and systems for cooling, dehumidifying and heating using multistage liquid desiccant regenerators, or hybrid cooling systems or adsorption cooling systems involving appropriate combinations of rotating contacting devises, adsorption modules with heat transfer passages in thermal contact with the adsorption module wall and switchable heat pipes. The sorption processes of this invention help in flexible designing of compact cooling, dehumidifing, heating systems easy operability. The adsorption module of this invention leads to lower cycle times as low as 5 minutes; makes it possible to achieve high system Coefficient of Performance (COP) up to 0.9 due to reduced thermal mass; offers high specific cooling power in the range of 50 to 750 W/kg of AC; is easy to manufacture and operates at low costs. The refrigeration cum heating system of this invention with heat pipe in thermal contact with the adsorption modules increase the heat transfer rates without increasing the thermal mass leading to increase of COP and the single or multistage pressure equalisation increases the internal regeneration of heat thereby increasing the COP, reducing the cycle time resulting in increased specific cooling power (SCP), reducing the required quantity of adsorbent/refrigerant making the module compact and cost effective.

A method and system for fabricating a device on a substrate with a process gas, such as with chemical vapor deposition. A reaction chamber and support chuck cooperate to form a low conductance configuration for axisymetric process gas flow over the substrate and to form a high conductance configuration for enhanced evacuation of residual process gas from the reaction chamber upon completion of the process. A dual conductance chuck has an indented region that aligns with the exhaust port of the reaction chamber to restrict process gas flow in the low conductance configuration, and that moves distal a showerhead and the exhaust port to provide reduced restriction of process gas flow for reaction chamber evacuation. The chuck includes thermal control for enhancing film deposition on the substrate and for reducing residual film deposition on the chuck. An evacuation opening in the housing provides independent evacuation of residual gas from the housing. The present invention enhance throughput of device formation by reducing purge and process cycle times.

A vapor compression system includes a timer and a controller for periodically starting up the system during the off-season periods (primarily non-cooling months) in which the system would normally be shut down. This provides periodic lubrication to the compressor components and prevents severe flooded starts due to excessive accumulation of refrigerant in the compressor (compressor oil sump in particular) and other system components. Provision is also made to sequentially turn on and off system components such as the compressor, the evaporator fan and the condenser fan to enhance the system operation. The timing sequences are provided for the time intervals between the startups, as well as the off-season operation cycle times.

The invention provides a macromolecule bonding adriamycin medicine, a nanometer capsule and a preparation method thereof. The bonding medicine is bonded by a block copolymer of poly ethylene glycol-polylactic acid and adriamycin. Firstly, the block copolymer of poly ethylene glycol-polylactic acid is acquired by ring-opening polymerization of aliphatic cyclic esters with poly ethylene glycol, solvent and catalyst being in existence; then a carboxyl end group is transformed by a hydroxyl-terminated; and then with a condensing agent being in existence, the carboxyl end group carries out amidation reaction with the adriamycin; thus acquiring the macromolecule adriamycin bonding medicine. The bonding medicine has amphiphilic property, thus being able to self assembly to prepare the nanometer capsule with a core-shell structure in the water solution. The adriamycin is wrapped inside the capsule to play a role of isolation and protection, which overcomes the deficiencies of short circulation time in vivo, large dosage and severe allergic reaction existing in the current adriamycin preparation. In addition, the nanometer particles are expected to congregate in the blood circulation through the so-called 'enhanced infiltration and retention effect', so as to improve the targeting action of the adriamycin on the tumor location.

The invention is related to a FVIII analogue which has a circulation time in the blood stream before activation of at least about two times of that of native FVIII and a week after injection to a patient retains at least about 5% of the FVIII activity compared to the initial activity peak value reached after injection. The claimed FVIII analogues comprise a targeted disruption of one or more of the clearance sites in the FVIII molecule by introduction of at least one N-glycosylation site or by introduction of at least one Cys residue within or spatially close to the clearance site in the A2 domain or a combination thereof. The inserted cysteine residues may be further modified by conjugation with a chemical group increasing the molecular weight of the FVIII analogue.
