An alarm device 20 for preventing unauthorized removal of a plug 22. of an electrical apparatus from a socket 10 which has electrically connected neutral and earthed sockets 14, 16, comprises a loop which is closed when,plug 22 is inserted in socket 10 by the interconnection 18 between sockets 14, 16, current being provided for the loop by the A.C. power which supplies socket 10 or by a battery 56 which has a manually operated switch 58, an alarm annunciator 60, e.g. a bell, being automatically actuated in response to the opening of the loop by removal of the plug. Mains current is rectified by diode 46 to charge a condenser 42 to a voltage higher than that of battery 56 so that the condenser is charged by the battery only when the mains fail or when the plug is removed. -Whenthe plug is in the socket the charge on condenser 42 flows through resistance 34, diode 48, L3, connection 18, L2 and back to condenser 42. If the plug is removed from the socket the charge from condenser 42 flows through resistor 34 and charges condenser 44 so that current will flow through a zener diode 52 to trigger thyristor 54 and activate alarm 60.

Abstract: 1363463 Matrix displays WESTERN ELECTRIC CO Inc 4 Nov 1971 [6 Nov 1970] 51311/71 Heading G5C [Also in Division H4] Display apparatus comprises a plurality of display cells, means 65 for momentarily changing the appearance of the cells sequentially, a transducer 90 for detecting the appearance of any selected cell and means responsive to the transducer for further changing the appearance of a display cell. Using a light pen transducer an operator can superimpose an image on an existing information display on a memory type gas discharge panel 50 in which a pulsed sustaining voltage maintains discharges in cells previously ignited by write pulses. A combination of a write and an erase pulse from a generator 65 is applied sequentially to each cell producing therein a light pulse. The pulses are invisible to an observer but a pulse is sensed by the transducer in an immediately adjacent cell. The transducer output via amplifier 95 and synchronizing gate 68 is applied to circuitry 40 to apply a write pulse to the said cell which subsequently remains on. The combination pulse is applied between sustain pulses and if the cell is already on it remains on. The transducer may also be used to erase parts of the display. The panel 50 may display data, TV, radar and computer information. The signals from the pen may be used to effect a display on another panel.

Abstract: 1291750 Valves ROBERT BOSCH GmbH 3 Nov 1970 [11 Dec 1969] 52197/70 Heading F2V A valve spool 12 controlling double-acting ram 15 is moved to either side of neutral against spring 22 by lever 13, and is held in its operated position by one of a pair of electromagnets 27, 28 co-operating with an armature 35 rockably mounted on an extension 18, 32 of the spool 12. The electromagnets are energized by closure of microswitch 40 by cam surfaces 42, 43 on projecting portion 33 of the spool extension. The electromagnet holding the spool in the position corresponding to upward travel of the ram piston is automatically de-energized when the piston-rod opens switch 45 at the end of its stroke. In a modification, the spool extension carries a rockable disc housing an electromagnet which is energized when the disc contacts live terminals, the electromagnet then co-operating with an adjacent part 24 or 25 of the valve body to hold the spool in its operated position. In both cases, the ram piston could de-energize the holding magnets at both ends of its stroke. Scraper rings are fitted at 26, 26a. The magnets can alternatively be de-energized by a pressureresponsive switch, or, if the armature is a permanent magnet, the holding coil could have a brief current reversal to repel the armature.

Abstract: 1,216,086. Prestressed concrete road or runway slabs. PHILIPP HOLZMANN A.G. 21 Nov., 1967, No. 52957/67. Heading E1G. A road or run-way is 'made of concrete slabs which are progressively stressed 'by successively severing one or more initially stressed elements around which the slabs are cast, for initial stress being chosen so that for a given configuration of slabs and elements when any severing occurs. the non-severed elements are stressed beyond their yield point, and below their ultimate braking point. In the embodiment shown, each slab has angular end plates 10-13 through which the elements 4 pass and to which they are secured by straps 26. The slabs are supported on concrete sleepers at their ends, with or without intermediate soilcent or concrete layers, e.g. 1a. The slabs are cast from the left as shown in Fig. 1, and anchor plates 25 are employed to resist any unbalanced longitudinal forces occurring during prestressing. Bitumen is used around the straps to prevent binding, and hard foamed plastics inserts 28 are placed adjacent the free ends of the straps. Transverse prestressing is achieved by elements 30, which are stressed together with a tie 33 by a jack (not shown). After the concrete is cast, the nuts 36 are released, the members 32 pivot, and clamps 31 and members 32 can be re-used.

Abstract: 1368429 Air conditioning BUCKEYE STEPHENS Ltd 9 Nov 1971 [10 Nov 1970] 53461/70 Heading F4V [Also in Division A1] An air conditioner 15 feeds a thermally insulated container 10 of an incubator with air at a temperature and absolute humidity lower than that of the desired incubating conditions in the chamber, the heat and water excreted from the eggs augmenting this air to produce the desired conditions. In a preferred embodiment a wet bulb thermometer 17 controls the rate at which an air intake fan 14 drives ambient air into the conditioning unit where its temperature and humidity is changed by a water bath heater 22 controlled by a wet bulb thermometer 21 and a water spray controlled by a dry bulb thermometer 26. This air passes through a filter 25 so as to remove water droplets before entering the chamber via the duct 13 so as to maintain the required hatching conditions by balancing the heat and water excreted by the eggs Auxiliary heaters 12 and coolers 20 are fitted inside the chamber to compliment the function of the air conditioner only in extreme ambient conditions. These two devices are controlled by a dry bulb thermometer 16 which also controls the intake fan 14. Instead of the thermometer 17, the fan 14 may be controlled by an element responsive to the dry bulb temperature or CO 2  content in the chamber.
