Portable wound treatment apparatus
A portable wound treatment apparatus, for stimulating the healing of superficial wounds, comprises a housing containing a suction pump and a canister for containing fluids drawn from the wound. The housing is supported on a harness or belt worn by the patient. The canister is connected to a porous wound dressing at the wound site via a plurality of tubes, a multi-lumen tube or a combination thereof. A rechargeable battery pack may be incorporated within the housing or externally thereto. The external battery pack may be shaped to balance the housing on the harness or belt. Pressure transducers are provided to monitor and report pressures at the wound site or internal to the canister. Monitored pressures may also be utilized to determine the filled state of the canister and, thereafter, either report this state to the operator or automatically discontinue suction from the wound, or both.

InactiveUS20080229745A1Increase flow volumeIncrease pressureMachines/enginesEngine componentsVertical planeMarine engineering
A wave energy converter includes a flexible pipe and an inlet. The flexible pipe floats on the water surface, following the wave form. Slugs of water and air enter, one after the other, through the inlet. Because the flexible pipe follows the shape of the wave, water is transported through a manifold to a pressure chamber connected to a generator. The inlet consists of a hollow, inflexible pipe attached to the throat of the flexible pipe. The inflexible pipe is fixedly attached to a buoyancy tank or plurality thereof. The buoyancy tanks are arranged in a vertical plane or in tandem, with the inflexible pipe passing along the plane vertical to the fore and aft axis of the buoyancy tank and the frontward portion projecting sufficiently ahead of the buoyancy tank with the flexible pipe terminating at a singular outlet.

Structural assemblies using integrally molded, and welded mechanically locking z-pins
InactiveUS20050042023A1Reduce stress concentrationAbility to controlMaterial gluingSheet joiningEngineeringHardness
A structure is provided which includes first and second layers. The first and second layers are attached to each other by embedding or otherwise attaching at least one mechanically locking z pin to the first layer and then subsequently joining the protruding portion of the z pin to the second layer prior to the second layer being processed to a fully cured state. Alternatively, the z pin material is injected into a cavity formed in the first and second layer and then brought to a fully cured state. The z pin may have physical characteristics such as orientation, melting point and hardness as a function of the physical characteristics of the first and second layer and the forces subjected upon the first and second layers. For example, the z pin may define a longitudinal axis and be embedded within the first and second layers in alignment with an applied force subjected on the first and second layers. This ensures that the z-pin is subjected primarily to tensile forces which allows designs to better control the failure mode of the attached first and second layers.

Continuous Tortilla Chip Cutter
InactiveUS20150135921A1PressureEffortMetal working apparatusFood preparationTortilla chipsProgrammable logic controller
A continuous tortilla chip cutting system where tortilla carried on a conveyor are continuously divided by a cutting mechanism into pre-cuts for frying into chips. A programmable controller drives a servo motor that moves an upper surface of the conveyor at a known velocity V, and a detector located above the conveyor at a known distance D from the cutting mechanism alerts the controller to the imminent arrival of the tortilla. The controller also controls a servo motor that actuates the cutting mechanism in a stop / start fashion. Based on the detection of the tortilla, the controller drives the servo motor associated with the cutting mechanism at just the right time and at just the right speed so that the cutter mechanism cuts each arriving tortilla into predictable sub-units called “pre-cuts” based on the velocity V of the conveyor belt, the detection of the flat bread unit carried by the conveyor, and the known distance between the moving flat bread unit and the cutter assembly.

An evacuation method used for a vacuum processing apparatus including a vacuum processing chamber is provided. The vacuum processing chamber is evacuated by an exhaust device for a first predetermined period of time by opening a valve connecting the exhaust device with the vacuum processing chamber. A pressure in the vacuum processing chamber is urged to increase by closing the valve and leaving the valve closed for a second predetermined period of time after evacuating the vacuum processing chamber. Evacuating the vacuum processing chamber and urging the pressure in the vacuum processing chamber to increase are performed so as to reduce the pressure in the vacuum processing chamber to a pressure between 6.7 Pa and 13.3×102 Pa (between 5 Torr and 10 Torr) without freezing moisture in the vacuum processing chamber.

Automated chemical polishing system adapted for soft semiconductor materials
ActiveUS20100120334A1PressureRegulate the amount of pressurePolishing machinesRevolution surface grinding machinesSemiconductor materialsControl theory
At least one wafer is suspended on a respective jig shaft above a polishing platen. The degree of parallelism between the wafer and the polishing platen is controlled using a three-point suspension, which allows for planar pitch adjustments using vertical actuation algorithms. As the wafer is lowered into contact against the polishing platen, a load cell senses how much of the weight of the jig shaft, wafer mount and wafer continues to be supported by the jig. The vertical displacement of the wafer is controlled using a linear actuator responsive to a signal from the load cell. Vertical actuation of the wafer serves to increase or decrease this amount of supported weight, in turn decreasing or increasing the amount of applied down-force exerted between the wafer and the platen. A compression spring is used to increase the resolution of the pressure control. Finally, system components exposed to the work environment are encapsulated by chemically resistive components to prevent corrosion of system components.
