Abstract: There is disclosed an improved spray tip for airless spraying of liquids in which the spray orifice is mounted in a rotatable turret member which is captured in a subassembly of a plastic spray guard and a tubular metal housing. The housing has a longitudinal through passageway which receives a floating piston seal member that has a forward, cylindrically concave face which is urged into a tight seal against the rotatable turret member by the liquid pressure which acts on the upstream face of the floating piston seal member. The floating piston seal member is sealed in the longitudinal through passageway by an annular seal which also restrains the turret member against rotation when the liquid pressure is released, thereby freely permitting substitution of spray orifices by interchanging of turret members.

Abstract: A solid state sensing element comprising a nonporous, structurally stable, electrically insulating substrate on which is disposed spaced apart pairs of electrodes for contact with moisture. A hygroscopic electrolytic material is located in close proximity to the electrodes as by coating the electrodes with the hygroscopic material. A catalyst is deposited in close proximity to the electrodes and is electrically insulated therefom. The electrodes are connected to a source of potential and current measuring instrumentation. Moisture is trapped by the hygroscopic material and electrolyzed at the electrodes. The catalyst recombines the hydrogen and oxygen thus formed to water so there is no net consumption of water by the element and equilibrium is established at the sensor surface and the atmosphere adjacent the sensor surface.

Abstract: A toy slot car system which simulates off-track racing. The system includes a track, toy vehicles and remote, hand-held controllers to permit each player to control the performance of a preselected vehicle. The track has coextensive, deep slots which have their sidewalls lined with electrical strip conductors, and the toy vehicles have a posts that are received in the deep slots and that carry electrical wipers at their lowermost ends. The surface of the track is rough and uneven with severe undulations which simulate off road conditions and which cause the toy vehicles to be jostled and thrown upwardly, above the track surface during races. Since the slots are quite deep and the electrical strip connectors are quite wide, the cars can bounce over the track and loose all wheel contact with the surface of the track, without loosing electrical continuity with the track, thus creating a realistic simulation of off-track racing.
