Title: A device for the remote controlled locking of doors
IPC: E05B81/24
Filed: 1979-02-05
Abstract: A device for the remote controlled locking of doors has a motor 6, a switch 5 located in the energizing circuit of the motor 6 and a lock actuable by a key to control said switch 5. Actuation of the lock causes corresponding movement in a first mechanical element 2 which operates the switch 5 to start the motor 6. This moves a second mechanical element 9 having a collar 12 which abuts on an element 14 to move the first mechanical element 2 to complete the action of the lock. The collar 12 then passes past the abutment element 14. The device is built in one structural unit in a housing 1 for ease of installation. The switch 5 may be connected to similar devices in other doors to lock or unlock them simultaneously with the first door. <IMAGE>

Title: Regulating apparatus for a heating or air conditioning installation
IPC: B60H1/00
Filed: 1979-10-19
Abstract: In a temperature control arrangement, e.g. for a vehicle interior, an electronic regulator 9 (Fig. 1) responds to temperature signals from sensors 5, 6, 7 and desired temp. setter 8, to control the delivery of an air pump 17 by controlling the excitation frequency or amplitude of the pump winding 21. The pump delivers pressurized air to a pneumatic actuator 11 which adjusts an air flap 4 until the interior temperature detected by sensor 6 equals the desired temperature. The flap is movable between limits wherein a forced air is caused to pass through a heat exchanger 3 or by-pass it. Alternatively the actuator 11 may adjust a valve in a heating water pipe. During steady state conditions excess air is vented to atmosphere via a throttle 15, or alternatively, via a solenoid operated valve 24. Alternative pump arrangements are shown in Figs. 2 and 3. Sensor 5 detects external air temperature and optional sensor 7 detects the temperature in air duct 12 downstream of the heat exchanger. <IMAGE>

Title: Gas turbine engine cooling air supply
IPC: F02C7/18
Filed: 1979-10-23
Abstract: An arrangement for cooling the cooling air for the turbine blades or other components of a gas turbine engine comprises a closed circuit system by which the cooling air is first cooled by heat exchange with water. Cooling air taken from the compressor discharge is passed through a heat exchanger 24 disposed between the combustion section 16 and the rotor shaft, the air being cooled by flow of water which is thereby evaporated. The steam passes through line 30 to a condenser 26 disposed around the engine air intake, the condensate passing to a pressurised reservoir 44 and feed pump 40 back to the heat exchanger. The cooled air passes to components for cooling thereof. The reservoir is pressurised by air taken from the engine compressor through accumulator 48. <IMAGE>

Title: Bradcast teletext system
IPC: H04N7/08
Filed: 1979-10-31
Abstract: Each broadcast page contains a row such as row 29 which is outside the set of displayed rows. In addition to the standard initial bytes CR (clock run in), FC (framing code) and MRAG (magazine number of 3 bits and row number of 5 bits), there are 4 bytes allocated to a 16-bit cyclic rundancy check code CRC for the page and 6 groups, of 6 bytes each, NEXT 0 to NEXT 5. Bytes are Hamming coded and thus contain only 4 message bits. Each 6-byte group is a pointer to another page address made up of page tens and page units (4 bits each), hour code tens and units (2 bits plus 4 bits) and minute code tens and units (3 bits plus 4 bits). The three spare bits from the tens bytes for hours and minutes contain a number which is normally 0 but, if not 0, is added modulo-8 in the decoder to the current magazine number in MRAG to derive the magazine number for the 'next' page. A decoder equipped with a multipage store can respond to the pointers to acquire a sequence of pages automatically, all available immediately to the viewer. A specific line, not related to any particular page, say magazine 8 row 30, can be transmitted say once a second and includes a 6-byte group addressing a title page. Whenever a receiver is switched on or to a channel carrying teletext, the decoder automatically responds to this line to acquire the addressed title page.

Title: Lock and key
IPC: E05B35/00
Filed: 1979-12-24
Abstract: A lock has a housing 12 in which one or, as shown, two bolts 40, 42 are mounted for sliding movement between a locking position and an unlocked position. Each of the two opposing faces of the bolts have allochirally arranged patterns of alternate lands 50, 52 and grooves 54, 56, extending obliquely across the bolts. The housing 12 has a keyhole 62 extending therethrough in which the shaft of the key is slidable. Opposite edges of the shaft have alternate lands 80, 84 and grooves 82, 86 complementary respectively to corresponding lands and grooves of latch bolts. To withdraw the bolts, the key is slid inwards so that successive grooves and lands on it engage successively the corresponding patterns on the bolts to cam them inwardly. The code of the lock may be readily changed by replacing the bolts with ones of a different groove pattern. Screws 122, 124 may be screwed in to holes 126, 128 to hold collars 114, 116 in the enlarged portions 108, 110 of grooves 96, 98 in the housing 12. This allows one of the bolts to be held in the withdrawn position thus preventing use of the key.
