摘要： An air throttle for an internal combustion engine having a shaft mounted butterfly vane mounted for rotation in the engine charge air inlet. The butterfly vane and shaft have an idle air bleed slot therethrough with a tubular idle valve mounted over said shaft for concentric rotation thereabout. With the butterfly vane closed for idle mode running, the idle valve is rotated between set limits to control idle air flow and idle speed. Upon rotation of the idle valve beyond the set limits, the butterfly is progressively opened for off-idle mode running speed control.

摘要： An air throttle (10) for an internal combustion engine has a butterfly-vane (16) mounted for rotation in the engine charge air inlet (15). The butterfly-vane is mounted on a rigid tubular shaft (18) having an idle air bleed slot (22) therethrough with a tubular idle valve (24) slip fit within the shaft for concentric rotation therein. With the butterfly-vane closed for idle mode running, the idle valve is rotated between set limits established by abutment surfaces (26) and (36) defined by slot (25) to control idle air flow and idle speed. Upon rotation of the idle valve beyond the set limits, the butterfly-vane is progressively opened for off-idle mode running speed control.

摘要： A quick-connect cartridge assembly includes a ring, a collar disposed within the ring, and an annular seal coaxially disposed with respect to the ring and the collar. A plug having a shank with an outer diameter substantially similar to the inner diameter of the collar is slidably received within the collar and is held within the collar by a friction fit. The plug is also received through the annular seal so as to establish a coaxial relationship with the ring, the collar and the annular seal. The plug includes one or more features for facilitating installation of the ring, the collar and the annular seal into a port and subsequent removal of the plug from the components after installation.

摘要： A method for making a carbon composite material includes coating a carbon-fiber meshed cloth substrate with a liquid form of a carbon source and carbonizing the coating on the coated substrate by heating the coated substrate to a carbonizing temperature. The thickness of the coating on the substrate is such that, upon carbonization of the coating, the carbonized coated substrate retains porosity and a discernible surface texture.

摘要： An improved rotory positive displacement blower (10) of the Roots-type with reduced airborne noise and superior efficiency. The blower includes a housing (12) defining generally cylindrical chambers (32, 34) having cylindrical wall surfaces (20a, 20b) and containing meshed lobed rotors (14, 16) having the lobes (14a, 14b, 14c, 16a, 16b, 16c) thereon formed with an end-to-end helical twist according to the relation 360.degree./2n, where n equals the number of lobes per rotor. Preferably, n equals three. The blower housing (12) also defines inlet and outlet ports (36, 38) and the intersections of wall surfaces (20a, 20b) define a cusp (20d) associated with the inlet port (36) and a cusp (20e) associated with outlet port (38). The inlet and outlet port openings are skewed in opposite directions to increase the time the top lands of the lobes are in sealing relation with cylindrical walls (20a, 20b) of chambers ( 32, 34). Transverse boundaries (20g, 20i) of the inlet port are traversed by the lobes prior to traversal of the inlet port cusp (20d) by trailing ends (14h, 16h) of the lobes. In a similar manner, the transverse boundaries (20n, 20r) of the outlet port are traversed by the lobes subsequent to traversal of the outlet port cusp (20e) by leading ends (14g, 16g) of the lobes. A portion of the cusp (20e) adjacent leading ends (14g, 16g) of the lobes is removed to provide a backflow passage for intercommunicating transfer volumes of one rotor not in direct communication with the outlet port with transfer volumes of the other rotor already in direct communication with the outlet port.

摘要： A coupling assembly includes a female member having a receiving end with an axially extending passageway and inwardly facing groove extending outwardly from said passageway in a position spaced from the receiving end. A split metal locking ring is positioned in the groove. A male member is sized to be received in said receiving end and includes a rib having a ramp where the ramp in a first embodiment curves outwardly to an apex and in a first alternate embodiment curves outwardly to a flat and in a second alternate embodiment increases in height in a linear fashion until a relatively short distance from the flat where it curves outwardly to meet the flat, the rib also has a shoulder tapering away from the forward end and inwardly toward the axis. Upon insertion of the male member into the female member, the split metal ring is expanded as it rides over the ramp, engages the cylindrical surface and retracts to a smaller diameter approaching its original size to engage the shoulder thereby locking the male member into engagement with the female member. A release sleeve is mounted on the male member and is axially movable relative thereto to push the split locking ring up and off of the tapering shoulder to thereby disengage the male member from the female member.

摘要： A pressure sensitive pad assembly for a brake pedal having in one embodiment a pair of plastic films with metallized surfaces spaced apart by apertured spaces and embedded in an elastomeric pad to be placed on a brake pedal. Application of a brake actuating force on the pad causes the elastomer to deform closing contact between the metallized surfaces for actuating a brake light. In another embodiment a pressure sensitive transducer pad assembly has embedded in elastomeric material, a plurality of piezoelectric strips which are deformed, upon application of a brake actuating force to the pad, for providing an electrical signal indicative of the magnitude of the brake actuating force. In another embodiment an elastomeric pad spans a shallow recess in a support with piezoelectric material provided on the spanning surface and deformation of the pad into the recess deforms the piezoelectric material to provide a brake actuating force signal.

摘要： An improved supercharger or blower (10) of the Roots-type with reduced airborne noise and improved efficiency. The blower includes a housing (12) defining generally cylindrical chambers (32, 34) containing meshed lobed rotors (14, 16) having the lobes (14a, 14b, 14c, 16a, 16b, 16c) thereon formed with an end-to-end helical twist according to the relation 360.degree./2n, where n equals the number of lobes per rotor. In one embodiment, blower housing (12) also defines inlet and outlet ports (36, 38). The inlet port includes longitudinal boundaries defined by housing wall surfaces (20f, 20h) and transverse boundaries defined by housing wall surfaces (20g, 20i). The transverse boundaries (20g, 20i) are disposed substantially parallel to the helical lobes. The outlet port includes longitudinal boundaries defined by housing surfaces (20m, 20r) and a transverse boundaries defined by housing surfaces (20p, 20s). The inlet and outlet port openings are skewed in opposite directions to increase the time top lands of the lobes are in sealing relation with cylindrical walls (20a, 20b) of chambers (32, 34). Expanding orifices (42, 44) defined by the intersection of transverse boundaries (20p, 20s) and longitudinal boundary (20m) are disposed substantially midway between ends (14g, 14h and 16g, 16h) of the lobe lands to reduce backflow noise.
