A linear pick-and-place drive mechanism for relocating articles with finite adjustable maximum translation stroke range and finite adjustable lift stroke range, using selective placement of a translation cam follower into one of several spaced adjustment holes along the length of a translation arm, and selective placement of a lift cam follower into one of several spaced adjustment holes along the length of a lift arm. Pivoting motion of both the translation arm and the lift arm is driven by a single plate-type drive cam having a translation cam track on one side thereof and a lift cam track on the opposite side thereof, resulting in minimal housing size and reduced power requirements.

A multi-beam satellite comprises an input section receiving a plurality of first spot beams and an output section transmitting a plurality of second spot beams. A payload architecture is coupled between the input section and output section. It flexibly and selectively switches and filters the first plurality of spot beams received by the input section and provides signals to the output section to be transmitted as the second plurality of spot beams.

Methods and nanocomposites for the adsorptive removal of aromatic hydrocarbons such as benzene, toluene, ethyl benzene and xylene from contaminated water sources and systems are provided. The nanocomposites contain carbon nanotubes and metal oxide nanoparticles such as Al₂O₃, Fe₂O₃ and ZnO impregnated on a surface and/or in pore spaces of the carbon nanotubes. Methods of preparing and characterizing the nanocomposite adsorbents are also provided.

A piezoelectric frame includes a tuning-fork type piezoelectric vibrating piece having excitation electrodes on each of at least two vibrating arms extending in a first direction from one end of a base portion thereof. Respective supporting arms extend in a first direction from respective external edges of the vibrating arms. An outer frame portion surrounds the tuning-fork type piezoelectric vibrating piece. The connecting portions have designated widths and connect the respective supporting arms to the outer frame portion. During manufacture, the designated widths are trimmed (e.g., by a pulsed laser) until the desired vibration frequency is obtained.

A method and associated system for processing waste gases, liquids and solids, produced by human activity, to separate (i) liquids suitable for processing to produce potable water, (ii) solids and liquids suitable for construction of walls suitable for enclosing a habitat volume and for radiation shielding, and (iii) other fluids and solids that are not suitable for processing. A forward osmosis process and a reverse osmosis process are sequentially combined to reduce fouling and to permit accumulation of different processable substances. The invention may be used for long term life support of human activity.

A multi-piece vehicle wheel assembly includes a wheel center and a lightweight wheel rim. The wheel center defines a center hole and has an outer margin. The wheel rim has opposing inside and outside major surfaces. The outside major surface defines a rim bed for mounting a vehicle tire. The inside major surface includes an inwardly-extending annular shoulder. A plurality of circumferentially spaced rim bosses are formed with the annular shoulder of the rim, and are adapted for engaging the outer margin of the wheel center. A corresponding plurality of circumferentially spaced fastener holes are formed along the outer margin the wheel center, and are adapted for aligning with the rim bosses formed with the rim. A plurality of fasteners are received through the aligned rim bosses and fastener holes to attach the rim and the wheel center together.

Disclosed is a transducer of an ultrasonic diagnosis device. Electrode patterns are formed inside a backing block, as one body, and thus, a prior art FPCB may be omitted.

The present invention provides an improved rocker arm system for actuating poppet valves in high performance internal combustion engines. The rocker arm provides journals extending from each side fitted to outboard bearing mounts to guide the motion of the rocker arm.

Roller chain links, both internal and external which include a link outer profile that contains at least one convex back edge. In an alternate embodiment, the link also contains a concave back edge. Additionally, the links may contain an extra hole or window within the link profile combined with the convex and concave edge profiles for additional mass reduction.

A tethering device for a boat may be mounted to a dock so that the top surface of the tethering device is flush with the top of the dock. Inside the housing is a retraction reel storing a sufficient length of line to provide tethering of the boat to the dock while retracting excess line back for out-of-sight storage but leaving the pre-selected length of line extending from the tethering device. The housing also has a line locking mechanism to hold the line at the pre-selected length so as to prevent the boat from drifting away taking line with it.

An arrow fletching apparatus with tapered body for use in the sport of archery is provided. The fletching apparatus is used in place of a fletching jig and glue conventionally used to fix fletching to an arrow shaft. The tapered body provides for an overall reduced weight of the apparatus.

An assembly adapted to be releasably attached to a mounting surface on a body panel of an automotive vehicle for mounting at least one component thereto includes at least one elongated rail member having a base portion that includes a first side adapted to be located adjacent to the mounting surface and an opposed second side. The rail member includes a pair of spaced apart flanges extending outwardly from the second side of the base portion. The base portion includes at least one aperture extending therethrough. The assembly also includes at least one fastening member that is adapted to be retained in the body panel by a retaining feature. The fastening member includes a backing plate portion having at least one flange extending therefrom and an aperture extending therethrough for receiving a fastener for releasably attaching the assembly to the mounting surface.

Provided is an improved hydroprocessing process allowing one to realize superior isoselectivity. The process comprises contacting a feed comprised of normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70.

Provided is an improved process for olefin oligomerization allowing one to realize superior selectivity. The process comprises contacting a hydrocarbon feed comprised of straight and branched chain olefins under oligomerization conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing for elimination of mass transfer in comparison with regular SSZ-70. The result is superior selectivity.

The object of the invention is a battery-operated welding and/or cutting device including a frame and at least one battery cell. The frame includes a cooling profile having an outer surface, which is in direct contact with the air surrounding the device. The cooling profile is provided to accommodate at least one battery cell, such that the cooling profile at least partly surrounds the battery cell in order to conduct heat from the battery cell to the cooling profile and, via the outer surface of the cooling profile, away from the device. The object of the invention is also a cooling profile.
