Title: Operation recorder for motor vehicle safety device
IPC: B60R21/16
Filed: 1972-12-12
Abstract: 1385939 Crash bags NISSAN MOTOR CO Ltd 12 Dec 1972 [9 Feb 1972] 57263/72 Heading B7B An operation recorder for a vehicle safety device, particularly for an inflatable air bag, is designed to indicate whether the device is actuated before or after the vehicle collision. A 12-volt D.C. source 10 is connected in series with a collision sensor switch 11 which is normally closed and is adapted to be opened on collision, an air bag actuation device 25, a switch 12 which is normally open and is adapted to be closed on actuation of the bag, and a recording device 13 which includes a fuse. If the bag is actuated before collision both switches 11 and 12 will be closed at the same time and current passing through the circuit will blow the recorder fuse indicating premature actuation. If collision occurs first switch 11 opens to prevent the blowing of the fuse. The normal switch positions may be reversed so that the fuse only blows if collision occurs before actuation of the bag. The bag actuation device 25 includes collision sensors 27, 28, an inflator detonating charge 26 and resistors 30, 31 across each sensor 27, 28. Prior to bag actuation the voltage at each of the points a and b will be 6 volts since R 30  # R 31  # R 26 , and after bag actuation the voltage at points a and b is 12 and 0 volts, respectively. Points a and b are connected respectively via an inverter 36 and directly to comparators 35 and 36 biased respectively at 8 and 4 volts. The comparators connect via a NOR gate 38 with a transistor whose collector is connected to the recorder fuse. Coils 45, 46, connected to the switch 11, prevent actuation of the bag actuation collision sensors 27, 28 until collision occurs.

Title: Device for smoothing the own course indicated by a compass
IPC: G01C19/36
Filed: 1971-12-09
Abstract: 1319398 Compass systems HOLLANDSE SIGNAALAPPARATEN NV 9 Dec 1971 [14 Dec 1970] 57277/71 Heading G1N A ship's compass in which the indication given by the compass 25 is smoothed by a slaved azimuth gyro 11 mounted on a stabilized platform (1) can assume a first, run-up, mode of operation for bringing an own course shaft 19 into position correspondence with the compass and setting the azimuth gyro 11 into correspondence with the own course shaft 19, and a second mode of operation in which the azimuth gyro 11 is slaved to the compass 25 and the angular position of the own course shaft 19 represents the smoothed own course. In the first, run-up, mode, switches 29 and 30 are in the positions shown and switch 39 is open. A servosystem 18 positions the own course shaft in accordance with coarse and fine signals from synchro receivers 27 and 26 on shaft 19 connected to transmitters in the compass 25. The servosystem 18 includes a coarse/fine selector switch 31, amplifier 41 and motor 42. Simultaneously, a gyro drive circuit 23 responds to a synchro receiver 22 on shaft 19 to drive torque motor 24 to position the azimuth gyro 11. A multipole synchro transmitter 21 is coupled to the gyro 11 and connected to the synchro receiver 22 whereby, if the number of poles is 11, the gyro 11 need be rotated through no more than 16À5 degrees. The gyro drive circuit 23 includes a demodulator 32, low pass filter 33, amplifier 36, integrator 37 (not used during run-up), summing circuit 38 and a matching amplifier 35. The second mode begins after a predetermined time. Switches 29 and 30 changed over and switch 39 closes. The gyro 11 is thus positioned in accordance with the output of the fine synchroreceiver 26 and servosystem 18 positions the own course shaft 19 in accordance with the output of the synchro receivers 27 and 22 so that its angular position represents the smoothed own course value. The gyro 11 is stabilized about a horizontal axis (15) by a servo loop comprising a pick-up (12), amplifier (13) and a torque motor (14).

Abstract: 1449900 Transistor pulse circuits SILCOX & SMITH Ltd 16 Oct 1974 [29 Dec 1973] 60137/73 Heading H3T [Also in Division H2] An automatic switching circuit for sequentially connecting a pair of output terminals 11, 12 across the respective terminals 13 ... 15 of series-connected batteries is energised by said batteries. As shown a double-pole change-over relay RL2/2 is periodically pulsed under control of a circuit in which a transistor TR1 is alternately turned on, while a capacitor C1 is charged via a resistor RV1, and then turned off while the eapacitor C1 is discharged. As described, in a tractor, a 12V battery connected to lines 11, 12 is alternately charged from a first 12V battery connected across 13, 14 and then from a further 12V battery connected across 14, 15 in dependence on the position of the contacts of relay RL2/2. C1 is charged via RV1 and normally-closed contacts of a further relay RL1 until zener diode ZD1 breaks down, turning on transistor TR1 which energises RL1/2, normally-open contacts RL1 of which energise relay RL2/2. Normally-open contacts RL1 short circuit zener diode ZD1 so that C1 discharges via the base circuit of TR1 until TR1 becomes non-conductive, releasing both relays. The operation is repetitive, each half cycle lasting for three minutes.

Patent GB-2036398-A (GB)
Title: Fence Disturbance Sensor Arrangement
IPC: G08B13/12
Filed: 1978-11-29
Abstract: To provide a local indication, in a fence disturbance sensor arrangement having a respective sensor on each of a plurality of panels of a fence, use is made of sensors each comprising a switch S1, transistors TR1 and TR2, an LED and a gated SCR connected with resistors R1 to R6. Each sensor is connected in parallel to positive voltage rail PVR, zero volt rail OVR, reset/indicate line RIL and reset/indicate control RIC, and signal analyser SA. Line RIL is normally held at a low voltage, e.g. of 5 volts. Thus, upon opening (even momentary of S1 as a result of disturbance of the respective fence panel, TR1 and TR2 trigger the SCR which is then turned on to allow passage through the LED of a small current which is insufficient to cause any significant illumination there of, and a signal is also supplied to analyser SA. Further operations of S1 cause further signals to be supplied to the analyser. When it is desired to check which sensor has operated, a higher voltage, e.g. 12 volts is applied to the line RIL, to cause discernable illumination of the LED of the sensor which has operated, the other sensors remaining non- illuminated. To reset the sensor, the line RIL is brought 0 volts for a moment to bring the SCR back to the non-conducting state. <IMAGE>

Title: Vehicle windscreen wiper variable-throw crank actuating mechanism
IPC: F16H21/40
Filed: 1978-12-12
Abstract: A vehicle windscreen wiper actuating mechanism comprises a reversible motor which drives a gear wheel 10. A crank pin 13 extends from the gear wheel 10 and has an eccentric member 14 rotatably mounted thereon. The eccentric member 14 has a cylindrical boss 21 whose axis is spaced from and parallel to that of the crank pin 13. A connecting rod 28 has a circular opening 29 engaged around the boss 21. The eccentric member 14 has an arcuate recess 27 in its underside. The ends of the recess 27 define first and second abutments 25 and 26. Stops 36 and 37 are defined by opposite sides of a projection 35 extending from the gear wheel 10 and engaging in the recess 27. A cup-shaped washer 30 rotatable with the eccentric member 14 is urged against the connecting rod 28 by a spring 31. In a forward direction of motor rotation, the first abutment 25 engages against the stop 36 so that a throw T1 of the connecting rod 28 is produced. In a reverse direction of motor rotation, a throw T2 is produced, T2 being greater than T1, movement of the eccentric member 14 relative to the crank pin 13 to change the throw occurs because of the frictional resistance differences in the bearing surfaces between the crank pin and the eccentric member and the eccentric member and the connecting rod. <IMAGE>
