IPC: B60S5/04
Filed: 1925-10-05
Abstract: 257,762. Fairbrother, H., (Air Scale Co.). Oct. 5, 1925. Roadside tyre-inflating plant. - A plant for delivering compressed air particularly applicable for inflating pneumatic tyres is fitted with a valve device adapted to interrupt the supply when a predetermined outlet pressure has been reached. A compressor driven bv an electric motor 2 and controlled by a regulator valve 3 supplies a reservoir 4 from which a conduit 5 leads to standards 6. Inside the standard, conduit 5 is connected by a coupling 9 to a filter 11 which is connected by pipe 5' and coupling 15 to the inlet nipple 40 of the regulating valve. The outlet nipple 43 is connected by a coupling 17 to the delivery conduit 16 which passes to the bottom of the standard and thence up through a post 6<1> to a head 22 fitted. with a counterweighted pivoted arm provided with a flexible connection 24 having a check valve 25 for attachment to the stem of the tyre valve. The regulating valve is secured as a unit by bolts 39 to bosses 36 formed in a housing 18 on the .standard, which housing has a window 31 held in place by a flange and bolts 33 and has the interior illuminated by an electric lamp 120 carried by a removable cover plate 117. The regulating device comprises a main valve 42 guided by wings 48 in a passage 45 and actuated by a pair of differential diaphragms 49, 63 separated by a spacer 65 and clamped between two parts of the casing on either side of the ported distance, ring 68. 'The actuating chamber at the back of the diaphragm 63 has a vent to atmosphere through a port 123 controlled by a needle valve 125 and provided with a muffling device, and is connected through a passage 6 controlled by an auxiliary valve 59 and passage 58 throttled by a needle valve 55 with the outlet side of the main valve. The auxiliary valve is actuated by a diaphragm 70 subject to outlet pressure and loaded by a weighted lever. The weighted lever has a slidable weight 91, whose position is indicated by graduations on the lever, and a counter balance weight 92 adapted to rub against an adjustable blade spring 96 whereby its movements are damped. The lever has a pivot frame 86 having a recess 89 adapted to engage a pointed extension on the pilot valve, spindle and a, slot 85 to receive a knife edge pivot 80 fixed to ears 79 on the cover 72 which is also provided with an adjustable stop 94. The weight 91 sits astride the lever 87, pins 99, 101 being provided to prevent its removal and has a slotted fin 103 adapted to engage between abutments 114 on a continuous cord running over pulleys, one of which is rota.table by a handle 110 outside the housing.

Abstract: 297,733. Soc. des Etablissements Gaumont. Sept. 26, 1927, [Convention date]. Optical recorcds and apparatus; combined kinematograph and ptonograph records. - A talking picture film has the sound and picture records superposed by mounting on opposite sides of a common carrier strip, or on separate superposed carrier strips, and the sound record is made by sound-modulated radiations which are outside of the range of the visible spectrum, such as ultra violet radiations. Gelatin is employed for the sound record and is bichromated before exposure and developed with tepid water; after exposure it is treated with a solution of salts, such as an ammoniacal solution of aesculin, which are opaque to the particular rays and impregnate only those parts of the film which are unaffected bv the sound. The superposed picture and sound films pass through the picture projecting and sound reproducing apparatus where the sound is reproduced by the particular rays acting on the record and influencing suitable receiving apparatus. The sound record can extend across the whole width of the picture record.

Title: Clutch control thrust bearing
IPC: F16D25/08
Filed: 1971-04-19
Abstract: 1323794 Clutch control SOC ANON FRANCAISE DU FERODO 19 April 1971 [31 March 1970] 25794/71 Heading F2L In a clutch control mechanism for a motor vehicle wherein an axially slidable control sleeve 21 operates a valve 50 controlling the supply and exhaust of pressure fluid to a servo 30 having a piston 24 which acts through a clutch release thrust bearing 38 and a sleeve 39 on the inner ends of spring fingers 19 of a diaphragm spring 15, axial reaction forces on the driving shaft are reduced by arranging the cylinder 25 of the servo to react on the clutch cover 13. The cylinder 25 acts through a thrust bearing 31 on a sleeve 32 fast with the clutch cover 13. A spring 52 biases the valve element 50 to the position shown in which it closes a compressed air inlet port 53 and a spring 60 biases the sleeve 21 and piston 24 apart to open an exhaust port 56. The exhaust port 55 is closed on initial axial movement of the sleeve 21 against the bias of the spring 60 and thereafter further axial movement of the sleeve 21 opens the inlet port 53 to supply compressed air to the servo chamber 30. The pressure in the chamber 30 moves the piston 24 left to follow the movement of the sleeve 21 and disengage the clutch. The effective area of the cylinder 25 is at most equal to the effective area of the piston 24 and preferably less than the effective area of the piston 24 to provide a feedback "feel" pressure through the control sleeve 21 to the clutch pedal. An initial clearance G 1  is provided in the clutch engaged position between the cylinder 25 and a valve housing 36 of the sleeve 21 to allow for clutch lining wear. Pins 65 prevent relative rotation between the sleeve 21, piston 24 and cylinder 25. A spring (62), Fig. 5 (not shown), may be provided between the piston 24 and cylinder 25 to ensure that the sleeve 39 remains in contact with the spring fingers 19 during clutch engagement. The pressure fluid may alternatively be suction or liquid pressure. In the event of failure of the fluid pressure supply, the sleeve 21 can act directly on the piston 24 to effect clutch disengagement. In Fig. 6 (not shown) a radial clearance is provided between the inner race of the bearing (38) and the piston (24) to permit the sleeve (39) to float radially and centre itself relative to the diaphragm spring. In Fig. 7 (not shown) the sleeve (21) slides on an extension (71) of the piston (24).
