Abstract: Disclosed is a rodless cylinder having a cylinder barrel with a slit formed axially therein. A piston is movably housed in the cylinder barrel. A mounting table is disposed movably along the external surface of the cylinder barrel and connected to the piston through the slit. An external actuator is mounted on the mounting table and designed to be driven by a pressure fluid. A passage, through which a pressure fluid can pass, is defined in the cylinder barrel. An inlet is provided in the cylinder barrel so as to introduce the pressure fluid in the passage to the mounting table side. An outlet is provided on the mounting table so as to supply the pressure fluid introduced from the inlet to the external actuator.

Abstract: A substrate for attaching infrared detector elements to multi-layer modules has a detector interface member to which the infrared detector elements are attachable and which is attachable to the multi-layer module so as to provide electrical communication between the infrared detector elements and the multi-layer module. At least one removable tab is formed upon the detector interface member and a plurality of probing pads are formed upon each tab. Conductive conduits formed upon each tab extend from the detector interface member to the probing pads so as to facilitate electrical communication between dedicated ones of the infrared detector elements and dedicated ones of the probing pads. The probing pads facilitate electrical testing of individual infrared detector elements.

Abstract: An apparatus for adjusting the positioning of a locating ring upon a drill bit. The apparatus comprises a housing having a drill seat attached thereto for slidably receiving the shank portion of the drill bit. The apparatus further comprises an adjustment mechanism which is attached to the housing for positioning the cutting tip of the drill bit at a desired separation distance from the drill seat. Also included is a reciprocal ram assembly attached to the housing for selectively bumping the locating ring into abutting contact with the drill seat subsequent to the insertion of the shank portion into the drill seat and the positioning of the cutting tip at the selected distance relative the drill seat.

Abstract: A non-slip sewing ruler comprising an elongate guide member including a pair of apertures disposed therein. Releasably attached to the top surface of the guide member is a handle member having a pair of pin members extending therefrom. Each of the pin members defines a pin point which is received into a respective one of the apertures when the handle member is attached to the guide member. The handle member is selectively movable between a first position wherein the pin points reside within the apertures, and a second position wherein the pin points protrude from the bottom surface of the guide member.

Abstract: The present invention relates to an improved walking beam assembly for use in the rear suspension of a heavy-duty vehicle. The walking beam assembly is constructed in a manner wherein the bushing segments incorporated therein may be easily removed and replaced. Such ease of replacement is facilitated by the polyurethane construction of the bushing segments. When inserted into the vehicle suspension, the walking beam incorporating the bushing segments is prevented from moving laterally relative the vehicle frame.

Abstract: A needleless injection site comprising a housing defining proximal and distal ends and including a reseal member disposed therein. The reseal member has an elastically openable and closable aperture formed therein, and normally resides within the housing in a closed position wherein the aperture is in a closed configuration. The reseal member is deformable such that the application of distally directed pressure thereto will cause the reseal member to distally advance within the housing to an open position wherein the aperture assumes an open configuration. The removal of the distally directed pressure from the reseal member will cause it to resiliently return to the closed position wherein the aperture assumes the closed configuration.
