IPC: F02P5/10
Filed: 1971-05-25
Abstract: 1293288 Timing ignition FORD MOTOR CO Ltd 25 May 1971 [6 July 1970] 16824/71 Heading F1B A spark timing control system comprises an engine carburetter 10 having an induction passage 18 containing a spark port 28 located above the idle speed position of a throttle valve 26 controlling flow through the passage and subject to the depression in the carburetter as a function of movement of the throttle valve from its idle speed position, an engine distributer having a breaker plate 12 pivotally movable in opposite directions to advance and retard the spark timing, vacuum controlled servo means 14 connected to the breaker plate for moving the same and slow fast flow-rate control means 53 between the spark port and servo means to control the rate of change of application of vacuum from the spark port to the servo means. The control means includes faster flow-rate means 62, 66 operable in response to a change in the depression at the spark port to a lesser depression than at the servo means to quickly equalize the pressure level at the servo means to that at the spark port and slower flow-rate means 76 operable in response to a change in the depression at the spark port to a greater depression than at the servo means to delay the equalization of the pressure level at the servo means to that at the spark port to delay the spark timing change.

IPC: B60Q1/34
Filed: 1925-07-01
Abstract: 258,943. Rea, D. H. July 1, 1925. Road-traffic signals on vehicles; lamp-group code signals. - Longitudinal shafts 1, 4 carrying signal arms or discs 9, 8 at the rear and front of the vehicle respectively are connected together by a shaft 6 so as to move simultaneously when a handle 5 is turned by the driver. The shaft 1 preferably is disposed beneath the vehicle frame while the shaft 4 runs over the bonnet. A coloured transparent window 18 in each arm is arranged to be illuminated by lamps 17 placed behind apertures 16 in each signalling position. A switch operated with the signalling means may cause only the lamp 17 corresponding to the signalling-position to be illiliminated, and a moving contact carried, e.g., by the shafts 1 or 4 may close the circuit of a bell or gong. The control handle 5 may be held in any desired position by a detent engaging a cog-wheel on the shaft 4.

Title: Improvements in or relating to recording apparatus for producing sound grooves for gramophone records
IPC: G11B3/08
Filed: 1942-12-01
Abstract: 563,351. Gramophones. PHILCO RADIO & TELEVISION CORPORATION. Dec. 1, 1942, No. 17092. Convention date, Jan. 7, 1942. [Class 40 (ii)] [Also in Group XXIV] The arm 13 supporting a recording device 14 over a gramophone turntable 11 is moved by a ratchet gearing during the recording operation. The arm 13 is mounted bv an horizontal hinge on a socket 18 attached to a vertical shaft 17 to which is also attached an arm 19. The outer end 40 of the arm 19 is arc-shaped concentrically about the shaft 17, and this arc 40 is frictionally gripped by a grooved pinion 27 fast with a spindle 26 and a ratchet wheel 28. The spindle 26 is carried by a swing plate 23 which is pivoted at 22 on the frame plate 20 and is influenced by a spring 25 to press the grooved pinion 27 against the arc 40. A lever 31 loose on the spindle 26 carries a spring- urged pawl 35 in engagement with the ratchet wheel 28, and has a bent extension 32 carrying a roller 33 in engagement with an eccentric or cam 34 on the hub of the turntable. This arrangement is such that during half of each rotation of the turntable, the lever 31 is turned in one direction and transmits movement through the ratchet and the grooved pinion to the arm 19 to feed the recording arm 13 inward ; and during the second half of each rotation of the turntable, the lever 31 is turned back by a spring 37, while the ratchet wheel 28 is held in position by a one-way gripping device comprising a cork disc 29 on the wheel 28 pressed against a metal disc 30 formed with bent-up teeth and attached to the swing plate 23, these parts being pressed together by a spring 55 held on the end of the spindle 26 by lock nuts 54. To put this mechanism out of operation when the recording arm 13 is moved to its off position outside the turntable, the end of the arc 40 has a recess 44 followed by a ramp 47 leading to a notch 43. When the recording arm 13 is moved outwards, the ramp 47 engages the pin 41, causing the lever 31 to turn away from the cam 34, and when the notch 43 reaches the pin 41, the pin is retained by the notch with the lever 31 away from the cam 34 and the recess 44 opposite the grooved pinion 27 until the recording arm is again forcibly moved inward by hand. While the recorder is out of action, a reproducer may be used, and the circuits may be switched over from recording to reproducing by a switch 45 operated by the outward movement of the recording arm to its off position.

Title: Improvements in or relating to air filters
Inventor: HAMMAN RONALD FREDERICK
IPC: F24F13/28
Filed: 1960-05-18
Abstract: 909,345. Air filters. SIMON Ltd., HENRY. May 1, 1961 [May 18, 1960], No. 17503/60. Class 8(2). Reverse flow cleaning of a plurality of inward flow filter sleeves e, Fig. 1, having their upper open ends supported by an apertured horizontal plate 14 which divides the filter casing into a lower dust-laden air chamber c and a filtered air chamber a having an outlet b is effected by compressed air pulses issuing through apertures in the sides of vertical tubes g projecting down each filter sleeve and connected to a header f mounted on a carriage 20 which is movable step-wise along tracks 15 in order to traverse the filter sleeves, an air pulse being supplied to the tubes g at the end of a movement step from a reservoir h and a cut-off valve k. The carriage 20 is driven between the extremities of the open ends of the filter sleeves by a chain 22, Fig. 4, passing round a pair of sprockets 23 one of which idles whilst the other is driven by a shaft 25 secured to a pair of rachet clutches 27 linked to the piston rods of spring-returned compressed air operated jacks 29 connected through a two-way selector valve 37 and a pressure-opening valve 35 to the reservoir h. In operation and assuming the reservoir from a supply line 31 through a valve 32, which is responsive to a predetermined pressure difference between chambers a and c, compressed air passes through valve 35 and valve 37 to one or other of the jacks 29 to extend the same and thus move the carriage 20 and tubes g a short distance along the sides of the filter sleeves. At the end of the stroke a jack cam 40 opens a pilot valve 41 to connect the operating member of the valve k to the line 31 resulting in a pulse of compresesd air being passed from the reservoir during its discharge through valve k to the tubes g. The jack is then retracted by its return spring, the associated pilot valve 41 and also valve k are closed and when control valve 32 is reopened by an increase in said pressure differential the reservoir becomes recharged and the cycle is repeated at intervals until the carriage reaches one end of its run. At this stage the carriage opens a valve 26 to allowaccess of compressed air from line 31 through a valve 34 (which is open only when the reservoir pressure is low) to the operating member of two-way valve 37 to switch it to its other position in which it controls the other jack for effecting the return run of the carriage 20. In a modification the several filter elements are arranged coaxially and the air duct revolves in steps about their axis. Specifications 768,634 and 887,309 are referred to.

[Class 40 (i)] [Also in Group XXIX] In apparatus for the proportional treatment by a chemical or reagent of a flow of liquid, a control pump provides a pressure or volume balance against a pressure or volume difference created by the flow, and a dispensing device for the reagent has its speed regulated by the speed of the pump. In one arrangement, Fig. 3 (not shown), a pressure difference obtained by a Venturi tube acts on a diaphragm operating contacts to control a reversible electric motor effecting the regulation of a variable-speed gear driving the pump which produces a balance of pressure on the diaphragm. From the pump shaft is driven the device adding the chemical or reagent to the liquid. In another arrangement, Fig. 4 (not shown), the flow-responsive diaphragm controls the height of water in a tank with adjustable outlet, to actuate a float controlling a 3-phase variable-speed commutator motor driving the pump.
