Title: A vehicle antiskid braking system
IPC: B60T8/40
Filed: 1969-12-01
Abstract: 1,256,023. Anti-skid braking systems. SOC. ANON D.B.A. 1 Dec., 1969 [27 Dec., 1968], No. 58609/69. Heading F2F. A vehicle anti-skid braking system with a master cylinder 10 supplying pressure fluid to front brakes via a conduit 18, and having an anti-skid control valve 38 controlling fluid to the rear brakes also has a relay valve 22 connected to a conduit 16, to a source of highpressure fluid provided by a pump 28 and accumulator 32 and to a conduit 42 leading to the rear brake cylinders 44. The valve 38 has a shut-off valve 56 and an exhaust valve 58 operated by solenoids electrically controlled by a device 52 in response to wheel velocity or acceleration sensing means 54. Upon actuation of brake pedal 12 fluid under pressure is supplied to the front brakes and to conduit 16 and causes a piston 94 to move and cause a plunger 114 to open a valve 84 to admit pressure fluid from the pump 28 which fluid passes to the rear brakes via output chamber 82 and conduit 42, the valve 84 being closed when the output pressure in conduit 42 is substantially equal to that from the master cylinder. If a wheel skids valve 56 is closed and valve 58 opened to decrease fluid pressure in conduit 42 which is thus connected to low-pressure reservoir 14. Such a pressure decrease which permits the wheels to accelerate again causes the piston 94 to move once more to open valve 84. In the event of failure of the pump 28 or conduit 26 a passage 120 and a non- return valve 122 allow emergency fluid flow from master cylinder 10 to the brake cylinders 44 via chamber 82 passage 112 and conduits 36, 42, a check valve 88 preventing flow to conduit 26. The piston 94 may be of stepped design so as to proportion the braking pressure.

Patent GB-750118-A (GB)
Abstract: 750,118. Indicating and recording-apparatus. STIRNEMANN, M. LEHNER-. April 2, 1954 [April 13, 1953], No. 9737/54. Class 106 (4). Apparatus for measuring the idle time of machinery comprises a number of time measuring counters Z0 to Z9, the first measuring idle time irrespective of its cause, the others measuring idle time only when associated switches are operated. The apparatus shown diagrammatically in Fig. 1 may be used with a loom. At the start of a weaving operation a main switch N is closed, a relay B operates to close contact b, a lamp S0 lights to indicate that the loom motor M stands still and a motor 1 rotates a cam 2 whereby a contact r is closed and opened at the rate of a hundred times an hour, the pulses generated being counted by a counter Z0 during standstill of the motor M. When a control switch P is closed, a relay A closes contacts a and the loom starts, while a relay C opens a contact c to extinguish the lamp S0 and stop the pulse generator so that the counter Z0 stops registering idle time. Upon breakage of a weft thread a switch D is actuated, opening contact d1 and closing contacts d2, d3, thus de-energizing relays A and C to stop the motor M and start the pulse generator. The lamp S0 signals the stand-still, the counter Z0 accumulates idle time and a lamp S7 signals the cause of the stand-still while a counter Z7 counts pulses to register the idle time due to weft breakages. Upon breakage of a warp thread a switch E is actuated, lamp S0 and counter Z0 operate as before, a counter Z8 counts idle time due to warp failure and a lamp S9 signals the cause while a counter Z9 in parallel therewith registers a single pulse and thus counts the number of warp failures. Idle time due to other causes is counted individually by counters Z1 to Z6 when switches F, G, H, I, &c., are closed, these being controlled respectively by the weaver foreman, the warp-man, the tier-on and the loom cleaver and so on. One main switch N is sufficient for all apparatus in one room or of an entire mill and it may be actuated by the main clock of the mill. A single central pulse generator could be provided for several or all the apparatus. The signal lamps 50 of a plurality of looms could be arranged on a central panel and stoppable acoustic devices could be connected across each. A counter across the lamp S7 could count weft failures. The circuit could be simplified by omitting the contacts f1 to l1 using the control switch P and relying on the foreman &c. to close his own switch as well. The relays and counters are further described with reference to Figs. 2 to 5 (not shown), provision being made for zeroizing all the counters by turning a single shaft by a triangular key through bevel gears. The warp counter is displayed beneath a window in the cover and the remaining counters are provided with type-wheels from which records may be printed on an inserted card by manipulation of a single lever.

Title: Audible warning system for indicating an operating condition of an internal combustion engine or a vehicle driven thereby
IPC: G05D13/04
Filed: 1980-04-03
Abstract: A resonator R actuated by airflow therethrough for producing an audible signal when a particular operating condition (e.g. transgressing of a threshold or malfunctioning) of the engine or some other component of the vehicle arises. As applied to a vehicle speed- control system, the throttle actuator 30 has an electromagnetic valve B which normally responds to an overspeed condition to open orifice 10, vent the bellows D and close the throttle. If valve B fails for some reason, then when the brake pedal 31 is operated, and the rod 33 moves to the left to open valve 37, air will pass through tube 38, resonator R and orifice 39 to vent the bellows. The resonator thereupon gives an audible warning that the valve B has failed. Other conditions which may be sensed to initiate a warning are a low level in a liquid reservoir, temperature of engine coolant or oil pressure.   <IMAGE>
