Title: Improvements in or relating to security arrangements for electrical systems
Inventor: HARRIS LIONEL ROY FRANK
IPC: H04M3/12
Filed: 1960-11-07
Abstract: 954,225. Automatic exchange systems. H.M. POSTMASTER GENERAL, STANDARD TELEPHONES & CABLES Ltd., GENERAL ELECTRIC CO. Ltd., AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd., ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and ERICSSON TELEPHONES Ltd. Nov. 1, 1961 [Nov. 7, 1960], No. 38168/60. Heading H4K. [Also in Division G1] In a set of interconnected interdependent electrical functional units in which a fault in one unit may affect the operation of another, fault finding is effected by automatically replacing units by like units in a predetermined sequence and automatically applying tests after each replacement. The invention may be applied to automatic telephone or telegraph exchange systems, or to computer and data processing systems generally. As shown, equipments A, B, C are interconnected in such manner that signals may pass both ways between A and B and between B and C and one way from A to C. Each equipment is provided with respective routine test equipments RA, RB, RC, under control of a fault analyser FA. When a routiner reports a fault, FA resets all the routiners and initiates a systematic replacement of such of the units A, B, C as could be responsible for the fault report, and in an order determined by fault reported. Thus suppose RA reports a fault which could be due to the malfunction of A or B. Then FA initiates replacement of unit A and the routiner RA is restarted. If the fault is no longer reported then unit A is indicated as faulty and the operation stopped. If, however, the fault still shows up then the routiners are reset, unit B is replaced, and a further routine test is conducted. Detailed circuitry for the equipment FA is provided, Fig. 2 (not shown), wherein different sequences are provided according to the nature of the reported fault. In a second embodiment, the equipments and their replacements are switched in, in all possible combinations, and an analysis of the fault reports made to indicate which units are faulty, and also to select a trouble-free combination for operational use. As shown. Fig. 3, a transmission path may pass either through equipment WA or SA and either through equipment WB or SB. Thus the control equipment, Fig. 4 (not shown), opens gates TG1 or TG3 and TG2 or TG4 in successive combinations for each of which a routine test is carried out and the result staticized. At the end of the cycle the staticized results are fed to gate combinations to indicate the faulty units, and used to enable appropriate ones of the gates TG1 . . . TG4 to provide an operational path. Specifications 940,016 and 954,226 are referred to.

Abstract: 968,094. Radio signalling. BURNDEPT Ltd. Nov. 21, 1960 [Nov. 19, 1959], No. 39343/59. Heading H4L. An emergency radio apparatus which serves as a radio beacon and also provides speech communication uses thermionic valves to generate the carrier and transistor circuits to modulate the carrier. For further economy transistor circuits are used to effect pulsing of the beacon signals. The input circuit of the carrier generator V2 is tuned to the third harmonic of the crystal XL and the. output circuit L3, C17 is tuned to act as a frequency doubler. Valve V3 acts as a frequency doubler and its output is supplied to the power amplifier V4. The apparatus may be worn by an aviator and includes a self-erecting aerial A which automatically operates switch M to close the battery circuits. With a switch S in position B the apparatus acts as a beacon and with the switch in position T or R it transmits or receives speech. The waveform of the beacon signals is a continuous wave of small amplitude which is audio-modulated, and during pulses is much increased in amplitude. To provide the amplitude changes the grid bias on valves V3, V4 is varied by means of a multivibrator T3, T5. The time constant of circuit C9, R16 is less than that of circuit C6 and R8 with thermistor TH2 in parallel and in the example given T3 conducts for 2¢ seconds and T5 for ¢ second. Valve V3 is biased via resistors R22 to R25 and valve V4 via resistors R23, R24, but when T5 conducts it causes transistor T6 to conduct and shortcircuit resistors R22, R23, R24, permitting greater amplification by valves V3, V4. An audio oscillator T4, via transformer 3, push-pull amplifier T7, T8 and transformer 4, modulates the carrier during the high power pulses, the feedback loop for the oscillator being completed via capacitor C15, speaking and receiving unit SU and resistor R21. With the switch S on contacts T the unit SU is connected via transformer 2 to amplifiers T1, T2, T4, T7, T8, to modulate the carrier, and on contacts R the aerial is coupled to a super-regenerative detector V1 and the resulting signals supplied via amplifiers T1, T2, T4, T7, T8 to the unit SU.

Hose is removed from inspection forms 14 (see Specifications 1,357,792 and 1,285,669) by clamps 22 comprising (Fig. 5) foam covered plates 78, 80 carried by chains 34, 40. The plates are spring pressed together and have cam followers 86, 88, 90 which engage cam members to open the plates. Each clamp positions a hose with one leg over a stacking tray 142 and the other leg over a fabric covered folding frame 140. A rack 158 can rotate the frame to fold the other leg on to the stacking tray. A flap 176 which is rotated out of the way during folding holds the folded hose down on the tray. The tray is progressively lowered within its frame 182 either by a set amount for each hose or by an amount determined by a photo-electric arrangement. There are a plurality of trays 142 which are in turn moved into the stacking position by pivotally mounted figures (196, Fig. 8, not shown) reciprocated by a fluid motor. Instead of folding the hose on to the stacking tray it may be folded the opposite way on to a surface 600 and packaged by hand or fed pneumatically to be packaged as in Specification 1,285,669; alternatively the longitudinally folded hose may be lifted off the stacking tray adjacent its toe portions by a clamp (306, Fig. 18, not shown) while a folding arm on a conveyer 260, Fig. 1, folds the hose transversely and then conveys the hose over an aperture 354 in a guide plate 250. A plunger 346 pushes the hose through the aperture, thus folding it again, and into a carton 370 (Fig. 29). The cartons are removed by suction cups from a magazine 406 and deposited on a rail 422. The cartons are fed intermittently to the filling and sealing positions by resilient fingers 504 which are reciprocated along the rail 22. The cartons comprise an outer cardboard sleeve having closure flaps at the ends which can be adhesively secured and an inner transparent plastic tube stuck to the sleeve.
