Patent GB-1266353-A (GB)
IPC: H04M19/00
Filed: 1969-01-30
Abstract: 1,266,353. Standby supply systems. POST OFFICE. 21 April, 1970 [30 Jan., 1969], No. 5205/69. Heading H2H. A power unit A for a telephone exchange comprises main and supplementary batteries of secondary cells 4 and 6 respectively, main and supplementary primary sources of electrical power 3 and 7 respectively, a further battery 10, a further primary source of electric power 9 and a switch 8 which is normally open but closes if the voltage across output bus-bars 1, 2 falls below a predetermined value, the source 3 normally providing the output of the unit and current for maintaining the batteries 4 and 6 in a charged condition. Under normal conditions the output of the unit A is provided by the sources 3, 9 which are mains rectifiers each providing 52 volts D.C. at 100 amps. On failure of the mains, batteries 4, 10 provide a 52 volt open circuit supply to the bus-bars, this voltage falling to 46 volts under load whereupon a sensor 11 closes the switch 8 to add the 5 volts of the battery 6. When the mains supply returns the switch 8 may remain closed if the batteries are substantially discharged and the sources 3, 9 recharge the batteries until the voltage between the bus-bars reaches 52 volts whereupon the sensor 11 opens the switch 8. A diode 5 ensures that the battery 4 is not directly charged by the source 3 but via the source 7 which produces 5 volts at 25 amps, thus limiting the charging current. Supplementary units B, C, having corresponding switches 8B, 8C, are added to the unit A as the current demand of the exchange increases. The switches 8, 8B, 8C may comprise thyristors and engine driven generators may provide a standby supply on failure of the mains.

Abstract: 1,266,485. Making cam-shafts; high-energy rate forming. KLOCKNER-HUMBOLDTDEUTZ A.G. 27 Feb., 1970 [1 March, 1969], No. 9530/70. Headings B3A and B3Q. [Also in Division F2] A cam-shaft is made by expanding a tube within a hollow die by internal pressure. One of the high-velocity methods may be used, e.g. explosive, electrohydraulic or electromagnetic forming. As applied to the latter method, the cams associated with one piston and an intermediate bearing may be formed in one operation within a die. Following the operation the tube is moved and rotated in the die before the next operation. The tube may be heated inductively by switching the forming coil to a heating circuit, e.g. by a timing relay preset to the required heating time or triggered by means responsive to temperature. Coolant may be circulated through the coil. In the example, a first operation of the coil 13 forms an end bearing 6<SP>1</SP>, a second forms a pair of cams, Fig. 2 (not shown), and a third the central bearing, the other cams being completed in subsequent operations. Plugs may be welded in the ends of the shaft and the bearings and cams hardened and ground.

Abstract: 1288509 Ventilating aircraft UNITED  AIRCRAFT CORP 19 Jan 1970 [24 Feb 1969]  2451/70 Heading F4V [Also in Divisions F1 and G3]  In an ejector 16 for feeding air to an air  conditioning package of an aircraft, having  variable area primary and secondary nozzles 18, 20 adapted to be fed respectively by bleeds 14, from the high and low pressure compressor stages of a jet engine 10, the area of the nozzles is variable essentially by a servomotor system 50 operating an actuator 42, the servomotor being responsive to pressure changes upstream of the secondary nozzle 20. Flaps 22, 24 control the area of both nozzles 18, 20. Levers 30, 32, 36 connect the flaps 22, 24 to a control piston 46 of the actuator 42, whose motion is controlled by a flapper nozzle 70 of the servomotor 50 arranged so that decrease in pressure upstream of the secondary nozzle and hence in conduit 54 causes opening of the flaps 22, 24. Cam 91 is attached to a push rod 94 operating the servomotor system and to the flaps 22, 24 and tends to stabilize the position of the flaps 22, 24. A temperature sensitive device 100 may be arranged downstream of the ejector 16 to operate a secondary servomotor system 102, 104, 106 connected to the control piston 46 by a conduit 49, so as to control the flaps 22, 24 with change of temperature. A conduit 108 causes pressure downstream of the ejector to act on a piston 110 which operates a rod 112 to limit the motion of the main lever 66 of the servomotor 50. Its effect is to open the flaps 22, 24 if the pressure in the conduit 108 becomes too low, and to close them if it becomes too high.

Abstract: 1335976 Change-speed control CAV Ltd 19 April 1971 [7 March 1970] 11038/70 Heading F2D In a manually operated power assisted five forward ratios and one reverse gear change control in which fluid pressure operated crossshift and gear establishing servo-motors 21, 22 and 19, 20 respectively, which in neutral are jointly pressurized in pairs to maintain a gear selector lever 15 in its central neutral position, are controlled by a manually operable lever 23 movable in the usual type gate 25, the lever 23 is pivotally connected to a shaft 24 carrying a cam disc 27 incorporating balk projections 37, 40 whereby movement of the manual lever 23 into a gear established position and/or subsequent return of the lever into the central neutral position is delayed by the balk projections 37, 40 respectively until the power operated function is completed, when the movement of the manual lever 23 into its correct position in the gate can be completed, the balk delay of the lever during each gear or neutral selecting stage forming a sensing signal to the driver indicative of when the next stage in the movement of the manual lever can take place. Gear establishing movement of the lever 23 along any one of the three gate slots from the central neutral slot turns the shaft 24 and hence cam 27 which via a lobe 28 operates one or other of valves 29, 30 to exhaust either servo 19 or 20 to axially move an arm 16 carrying the gear selector 15 to a gear established position, the balk projections 37 on the cam disc 27 striking a valve plunger 34 preventing full movement of the manual lever 23 until cams 38 on the arm 16 operate a fluid pressure or electromagnetic valve 36 on completion of the gear establishing movement of the arm 16 whereby the valve plunger 34 is withdrawn to correspondingly allow the driver to manually complete the movement of the lever 23. Movement of the manual lever back out of the gear established position towards the neutral slot is similarly delayed by the balk projections 40 which when the lever is moved to release the valves 29 or 30 to re-centralize the arm 16, initially strikes a plunger valve 33, preventing centralizing movement of the lever 23 until a cam 39 on the arm 16 operates a further valve 35 (similar to valve 36) on completion of the re-centralizing of the arm 16 into neutral whereby the valve plunger 33 is withdrawn to again allow the driver to manually complete the movement of the lever 23 into the central neutral position. Gear selecting movements are effected by simply pivoting the lever 23 in a slot in the shaft 24 along the neutral gate slot to operate one or other of the control valves 31, 32 to exhaust one or other of the servos 21, 22 respectively to thereby rock the gear operating lever into engagement with the appropriate striker rod.
