An overrunning coupling assembly includes a notch plate and an annular coupling pocket plate positioned in face-to-face relationship with respect to each other along a common axis. The pocket plate includes strut pockets disposed at angularly spaced positions about the axis. The notch plate includes notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. The notch plate includes an inner circumferential rail at a radially inward side of the notch recesses and an outer circumferential rail at a radially outward side of the notch recesses. Torque-transmitting struts are positioned in the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is engageable with one of the notch recesses whereby one-way torque transfer may occur between the plates. Each opposite edge has first and second corners. Each strut pocket is sufficiently enlarged to allow pivotal movement of each strut about a strut axis which is parallel with the common axis, thereby enabling one of the first and second corners to be selectively supported by one of the inner and outer circumferential rails to prevent the struts from slapping against the notch recesses as the notch plate and pocket plate are respectively counterrotated.

A closing device for drawers, the device having a housing with a holding notch and a slider having a resilient latching arm that is bendable to engage the holding notch, as well as a spring that engages the housing and the slider to urge the slider to a rearward position relative to the housing. The resilient latching arm has a slot adapted to receive a pin, whereby as the drawer is moved from its closed position, the relative movement of the pin advances the slider to a position where the resilient latching arm engages the holding notch and the drawer is free to mover further outward without influence of the closing device. As the drawer is moved rearward toward its closed position, the relative movement of the pin will cause it to engage the slot in the resilient latching arm, further causing it to release from the holding notch and to be urged by the spring to move the drawer toward a closed position.

A work hardened articulating surface for anatomical prosthetics. Articulating surfaces of prosthetics are work hardened to decrease the wear and increase the longevity of the prosthetic after implantation. The articulating surface can be hardened in any number of ways, for example the articulating surface can be formed from stock material that has been work hardened throughout or the articulating surface can be work hardened prior to final finishing of the prosthetic component. Regardless, the hardened articulating surface reduces wear after implantation while eliminating the need for a separate bearing component.

An electronically activated gas cooktop control system, responsive to a touch-sensitive user interface, and capable of providing a predetermined range of cooking and simmer levels of BTU output, has two complementary heating modes of operation A first heating mode of operation is provided to produce a wide selection of simmer levels of BTU output, by electronically sequencing a solenoid-operated modulating gas valve “on” and “off”, at a predetermined level of flame. A second cooking mode of operation is provided by electronically modulating the level of flame, through use of a pulse-width-modulation (PWM) output signal to produce a wide selection of cooking levels of BTU output. An igniter system capable of insuring proper ignition of gas without generating harmful electromagnetic interference is also provided.

A pedal assembly for a bass drum or high hat cymbals. A flat base plate has a resilient pedal board clamped to it with the pedal board inclined to receive a foot. A beater stick is connected with the toe end of the pedal board by a linkage that drives the beater stick against a bass drum when the pedal is depressed. The resiliency of the pedal board returns it to its normal position when foot pressure is withdrawn. The material of which the pedal board is constructed has a modulus of elasticity between about one million and about six million. A striker pad limits the depression of the pedal board to limit the force that the beater stick can apply to the drum.

This invention is an apparatus and method for reversible intermodal conversion of transport tractors and trailers, highway-to-rail. Trailer add-ons are wheel mount shims and an axle housing draft sill pin receptacle. No add-ons are required for tractors.
