Abstract: A vehicular seating assembly (14) includes a seat cushion (20) and a seat back (22). The seat back (22) is locked in the seat forming position when the pawl (46) is locked into the seat back notch (54) by the bell crank (34). When the seat cushion (20) is moved out of the seat forming position, the spring (52) forces the bell crank (34) to rotate (counter clockwise in the Figures) unlocking the pawl (46) from the seat back notch (54). The torsion bar (32) receives the seat cushion (20) when the seat cushion (20) is returned to the seat forming position rotating the bell crank (34) back into locking engagement with the pawl (46) via a linkage (36).

The apparatus may also be used for determining web graphics distortion.

Abstract: A method of making a filamentary structure comprising a spiral thermoplastic core filament disposed within a thermoplastic sheath component is provided. The method involves extruding together from an extrusion die filaments forming the core filament and the sheath component, with the core filament being extruded at a faster rate than the sheath component which causes the core filament to spiral, and cooling the extrudates to form a unitary structure. A plurality of the filamentary structures may be extruded side-by-side so that their sheath components are joined together to form a fabric structure.

Abstract: Electrode clip for attachment to a TENS electrode or other medical electrode including a slide actuator within a grooved channel for moving longitudinally and rotationally positioning an upper contact body including an integral contact over and about an interceded electrode contact assembly, and securing the electrode contact assembly over a lower contact integral to an electrode clip main body. The sliding actuator includes catches and latches in the sliding actuator and related structure for positioning to actuate and to secure the electrode clip upper contact body in a secured or unsecured position over the main body. Spring contacts in the lower main body contact assembly provide electrical continuity between upper and lower contacts for ensuring electrical contact between the upper and lower contacts and an inserted electrode.

Abstract: Connector system such as for medical applications, which includes a yoke with inset pins, the yoke also including a locking feature for mating with an insulated connector, and locking the insulating connector into the yoke. The yoke includes at least one or a plurality such as three or more inset pins in the yoke for receiving insulated connectors such as for breath, heartbeat, and rate monitors. The yoke is formed in a three step molding process where colored buttons are first molded, the buttons and pins are then molded into a small inner yoke body assembly, and then a final yoke assembly is molded encompassing the pins, buttons, informational plaque, including a strain relief for the cable. The connector system provides for safety as well as FDA considerations and prevents a connecting lead being plugged into an AC outlet.

Abstract: Means are provided for continuous filtration of foreign matter from a fluid stream, without requiring a discontinuance of filtration to clean filter surfaces. The apparatus alternately directs the fluid to be filtered to one or another of a plurality of filter compartments, each containing a filter medium. Sensing means are provided to sense the condition of filter clogging in the compartments, and diverting means are provided to divert the flow of fluid to a compartment having a relatively clean filter, when a clogging condition is sensed. Thus, the fluid stream is always directed to a filtering compartment having relatively clean filter media therein. Additionally, means are provided for cleaning the filter medium in a compartment not being used.

Abstract: In making a plastic bag having a filling pipe, to overcome the difficulty of separating the overlying walls of a flattened tube of plastics material, one wall (11b) of the flattened tube (10) is cut to form a flap (17) and the opposite wall (11a) of the flattened tube is cut to form an opening (14), registering with at least a part of the flap; two pairs of clamping members (22, FIG. 4) engage the flap at the location of the opening and are moved to cause the flap (17) to extend out of the plane of the first wall of the tubing; and the filling pipe (26) is then inserted between the pairs of clamping members (22) and on the inner side of the displaced flap to enter the space between the overlying walls of the tube. Thereafter the walls of the flattened tube are sealed around the filling pipe.

The spiral core filament and the sheath component may comprise the same or different thermoplastic polymers, suitable polymers being polyamides, polyesters and polyolefins.The core filament and the sheath component may be extruded together from a spinning jet, and a plurality of the filamentary structures may be extruded side-by-side so that their sheath components are joined together to form a fabric structure.

Abstract: A marking device for a shorthand machine selectively marks the margins of the paper tape output of the shorthand machine to denote a portion of the shorthand notes for ready reference. The activating keys for the device are located in close proximity with the machine keyboard, whereby the operator may activate the device with minimal interruption of the recording process. Disposable marking instruments may be employed in the device. Incorporation of the device in the machine cover preserves the first planar surface of the cover and further, facilitates storage of the device when not in use.
