Title: Occupant restraint airbag system for vehicles
IPC: B60R21/01
Filed: 1972-12-28
Abstract: 1390689 Automatic fault indication HITACHI Ltd and NISSAN MOTOR CO Ltd 28 Dec 1972 [29 Dec 1971] 59820/73 Heading H2K [Also in Division G1] An automobile air-bag system includes means 21 for detecting a collision and inflating the airbag, fault detecting means for detecting a fault in the means 21, means 50 for recording an output from the fault detecting means, and means 51 for disconnecting the recording means on detection of a collision. In the arrangement shown, a fault lights an indicating lamp and causes a signal to appear at a terminal 502 to render a transistor 503 conductive. This causes a transistor 506 to stop conducting to allow a capacitor 508 to charge until a zener diode 512 breaks down. Transistors 510, 511 now conduct and cause the blowing of a recording fuse 513. The collision detector 21 may interrupt the supply at 51 or render the output signal of the fault detecting means ineffective so that a collision would not cause operation of the means 513. In an alternative arrangement, Fig. 5 (not shown), the fault signal causes a transistor to conduct to cause current to flow through an electrolytic recording device in which the reduction in length of a copper electrode rod indicates the duration of the fault.

Filed: 1971-12-23
Abstract: 1373810 Feeding sheets XEROX CORP 23 Dec 1971 [28 Dec 1970] 59885/71 Heading B8R In a sheet separating device, a pile of sheets 14 is supported on a plate 12 having a contoured surface 76 to deform the sheets of the pile so that the force acting through separating rollers 34 accommodated on apivotable arm 58 remains at right angles to the deformed portion of each sheet that the rollers contact as the pile diminishes and the arm is lowered. At commencement of separation of sheets from a full pile, the arm 58 is nearly horizontal and the topmost sheets are deformed little as a result of the bulk of the pile underneath resting on the contoured plate. As the pile diminishes, however, the arm pivots downwardly but as the lower sheets assume the inclination of the contoured plate the force acting through the rollers remains normal to the deformed surface of each sheet. The roller may firstly be rotated in reverse to free the topmost sheet from snubber tabs 44 and to buckle it against a backstop, then forwardly to separate it and feed it on to rollers (not shown). The tabs may be connected via a hinge 46 and torsion springs to adjustable pile side guides (48), (50), Fig. 2 (not shown). The plate 12 may be of plastics material having neoprene and cork pads thereon, the rollers 34 being rubber covered.

Patent GB-720699-A (GB)
IPC: H04W84/02
Abstract: 720,699. Radio signalling. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 12, 1953 [Feb. 15, 1952], No. 3981/53. Class 40 (5). Relates to systems having a main station which communicates with a plurality of substations and provides for the transmission of a modulation tone from the main transmitter, which disables all the substation receivers except those which have responded to a call, automatically on the receipt of the response. At the main station, Fig. 1, the output valve 10 of the receiver 7 ... 12 is blocked, when no carrier is received, by a circuit 13 in which an amplifier/rectifier 16, 18 is fed from the detector 9 with noise or other voltages outside the speech-frequency band, through filter 14, 15. The blocking voltage is the difference between the rectified voltage across resistance 19 and a fixed voltage across resistance 20. When a signal is received from one or more of the substations the noise voltage decreases and valve 10 is unblocked to feed the loud-speaker 12 and to operate a relay 11. The contact 62 is thereby closed to connect a tone generator 63, operating at, say, 12 Kc/s, to modulate the transmitter 1 ... 6. At the receivers which have not responded to a call, this tone fre. quency blocks the output valve. The substation receivers have a blocking circuit 37, Fig. 2, similar to circuit 13 at the main station, which disables the output valve 36 of the receiver 33 ... 36, 55. When the main station transmits a calling carrier, the valve 36 is unblocked and the loud-speaker 55 rendered operative. At those stations called, the operator lifts the microtelephone handset 28 which operates switch 54. Contacts 56, 57 are thereby closed to connect the telephone and microphone in circuit, contact 58 operates relay 60, 61 to start up the transmitter 27, 29 ... 32 and contact 53 shunts a resistance 52 across a tuned circuit 50, 51 in the anode circuit of the blocking valve 38, 40. In the receivers of those substations which have not responded to the call, circuit 50, 51, which is tuned to the frequency of the tone generator 63 at the main transmitter, responds to this tone transmitted from the main station and provides a blocking voltage for the output valve 36.

Title: Improvements in or relating to control systems for compressors
IPC: F04C28/06
Filed: 1978-09-11
Abstract: In a control system for compressors 11 operating in bank a stop signal to the motor of any compressor is inhibited if the compressor oil temperature is insufficient to prevent emulsification of the oil. A stop signal generated by a high pressure sensor 15 is applied to one compressor at a time by a sequencing switch 17 via a respective gate 23 and delay means 27, the gate 23 additionally receiving a signal from an oil temperature sensor 29 of the respective compressor. The stop signal applied to any compressor is also applied to a driver 18 of the sequencing switch 17 to step the switch on to the next compressor. A second sequencing switch 22 driven by the same driver 18 applies a start signal to the starter 13 of one compressor at a time, the start signal being generated by an autostart 26 circuit responsive to signals from a low pressure sensor 16 and the start/stop circuits of all the compressors. The start signal applied to any compressor is propagated to the next compressor via respective delay means 27 and a gate 28 that receives additionally the signal from the low pressure sensor 16 whereby the start signal is inhibited if the low pressure sensor signal is not present. <IMAGE>

Patent GB-2019595-A (GB)
Title: Automatic focusing
IPC: G03B13/36
Filed: 1979-04-19
Abstract: An automatic camera focusing mechanism comprises a first electronic register for storing a number representative of the actual distance of the camera from the object (determined using bounced ultrasonic energy), a second electronic register for storing a number representative of the actual setting of the lens (determined using a grey code disc and grey-to-binary converter), a magnitude comparator which is responsive to a difference in register contents to operate a lens driving motor, and means for inhibiting the motor when the register contents are equal. In a cine camera, the content of the first electronic register varies at a rate dependent on the rate of actual distance determination, and the content of the second electronic register varies at a rate dependent on the rate of change of lens position. A reduction in lens hunting and a smoother change in focusing are effected by passing signals from the comparator to first and second shift registers and operating the motor, after a predetermined number of signals, in dependence on which register has the majority of signals.

Title: Control devices for web-feeding machines
IPC: B65H18/10
Filed: 1980-02-06
Abstract: Winders or sheeters are arranged to stop when a desired length of web has been fed by accurately-timing the start of deceleration from full speed. In a control device, incorporating a microprocessor, or dedicated circuit, the web speed is sensed by a transducer which delivers a signal from which is calculated the length of web which will be fed during standard deceleration. The result of this calculation is compared with the difference between desired length and length already fed (or the result plus length already fed can be compared with desired length) and when the result of this comparison indicates deceleration should start a signal is sent to the braking system. Alternatively, a data storage device may be provided containing a table, for a range of web speeds, of the corresponding lengths of web fed during controlled deceleration.
