Abstract: A multifunction vehicle seat reduces the impact peak and decreases the transfer of acceleration and deceleration forces to all regions of the occupant's body during frontal, rear-end and lateral collisions at high and low speed impacts or when collision becomes inevitable. The seat is isolated from the structural integrity of the vehicle by an anti-friction ball and a plurality of stabilizers. The anti-friction ball is adapted for universal movement over a movable base plate to reduce the transfer of kinetic energy to the seat and to the occupant. The stabilizers are interlocked and engaged with the seat support assembly to delay the response of the seat to the impact until a pulley system is activated. The pulley system is activated electronically or manually to deform the seat cushion, seat back and headrest during and before impact.

Abstract: A valve seal for a rotary valve assembly for use in an internal combustion engine of the piston and cylinder type, the valve seal having a valve body member having a curved annular upper surface conforming to the spherical periphery of a spherical rotary valve, the valve seal having a centrally disposed aperture therethrough defined by an inner circular side wall, the valve body member having an annular receiving groove formed on its curved upper surface for receipt of a lubricating insert ring, the valve body member further having an outer circumferential side wall having a plurality of mounting ribs for the positioning of lateral sealing rings, the valve body member further having a plurality of radial throughbores formed between the inner circular side wall and the outer circumferential side wall, the throughbores being in the same plane as one of the sealing rings.

Abstract: A self-normalling jack with an electronically controlled normal circuit or relay comprising a pair of receptacles having a sensing means for sensing the insertion of a plug, the sensing means in communication with an electronic normalling switch or relay, the electronic normalling switch or relay in communication with a paired receptacle such that the electronic normalling switch or relay is located between the source terminal and the upper jack and between the lower jack and the destination terminal. The electronically controlled normalling circuit or relay also connects the source to the destination when no patch cord is inserted into either the upper or lower jack receptacle. When the patch cord is inserted into the upper jack, the source signal is connected to the patch plug. When the patch cord is inserted into the lower jack, the destination signal is connected to the patch plug. Inserting a cord into either jack receptacle disconnects the source from the destination.
