Title: Anti theft devices for vehicles
IPC: G08B13/22
Filed: 1962-04-06
Abstract: 1,056,062. Vehicle anti-theft devices. R. W. HOMEWOOD and W. E. GODDARD. July 8, 1963 [April 6, 1962], No. 13368/62. Heading F1B. [Also in Division G4] A vehicle anti-theft device comprises a switch means 10-12 settable according to a code to disconnect the electric supply line A, a switch RL1/2 closed by closing of the driver's door, to connect the current supply to relay RL2 which operates switches RL2/2, RL2/3 in the circuits of alarm or immobilizing devices, and a delay device TD1 which prevents closing of the circuit of relay RL2 by a switch SW2 operated by opening of the driver's door for a period long enough to allow the driver to de-energize the alarm circuit by resetting the switches 10-12. The relay RL2 controls a switch RL2/2 of an audible alarm and a switch RL2/3 in the ignition circuit. A second relay RL3/1, controlled by a switch SW3 operated e. g. by opening the bonnet or boot lid, controls a switch RL3/2 of a second alarm. When the driver leaves the vehicle, having set switches 10-12 to operative position, closing of his door energizes relay RL1 to close switch RL1/2 to supply current to relay RL2. Any unauthorised opening of the driver's door closes switch SW2 to complete the circuit of relay RL2 which, after the predetermined delay, e.g. 5-10 secs, controlled by device TD1, operates switches RL2/2, RL2/3 to operate an alarm and break the ignition circuit. Alternatively, opening of the bonnet or boot lid causes immediate operation of the alarm switch RL3/2.

Title: Improvements in or relating to remote control receivers for audio frequency central remote control installations superimposed on a network
IPC: H02J13/00
Filed: 1958-04-29
Abstract: 847,437. Electric selective-signalling systems. LANDIS & GYR A.G. April 29, 1958 [May 9, 1957], No. 13568/58. Class 40 (1). As described in a broadcast control installation, the first five pulse positions g 1  to g 5 , Fig. 1, after a start pulse S 0  are devoted to a call sign which selects a particular remote field station and prepares it for responding to the following two, 1 and 2, control signals. Subsequent control signals 3 and 4 &c. are effective, in the usual manner, at every field station. Each field station, Fig. 2, includes a call sign recognition device GZ, referred to in the Specification by the synonymous terms mechanical servo-lock and group auxiliary, which is driven by the main synchronous shaft a of the field station and has a lever U rocked by a solenoid G by each pulse received by the field station, and which, when it receives the call sign it is set to recognize, closes a contact gz, thereby preparing the first two contacts 1 and 2 of the synchronous distributer W, for reception of the control signals 1 and 2. The call sign recognition device comprises a plate P, Fig. 5, having five holes therein, positioned to correspond with the call sign to be recognized, five levers C 1  to C 5  which are raised singly in succession in the five pulse positions g 1  to g 5  (see Fig. 1) by five cams n 1  to n 5  on the main synchronous drive shafta and five spring reeds F 1  to F 5  integral with a plate rocked by the lever U every time a pulse is received. In operation, when a pulse is received at any one of the five pulse positions g 1  to g 5  the corresponding lever, for example lever C 3  is latched in its forward position by a protrusion b on it and then at the end of the fifth pulse position g 5  the levers C 1  to C 5  will be in positions corresponding to the received call sign. A cam nc which co-operates with the supporting frame T of the plate P, then releases the frame T which tends to spring upwards to close the contact gz, but this is only possible if the positions of the levers C 1  to C 5  correspond to the positions of the holes in the plate P, that is to say the contact gz is only closed if the appropriate call sign has been received. The holes in the plate P can be formed by recesses in slidable bars (Fig. 6, not shown), in which case they can be adjustable.

Classes 83 (2) and 83 (4) An improvement in or modification of the method of making sintered aluminium bodies described and claimed in the parent Specification is characterized by the use of a superficially oxidized flaky aluminium powder having a bulkweight of at least 0.7 kg/l., an aluminium-oxide content of at least per cent and a total lubricant content of less than 0.4 per cent. The powder may be made from foil of 99.2-99.5 per cent purity with 0.4 per cent added stearic acid in a round-stamper. The foil is first reduced to a particle size of 3.3mm and then to 0.7mm. It is then further reduced in a ball mill for 10 hours in a nitrogenoxygen atmosphere. The oxide content may be varied from 8-15 per cent, the lubricant content 0.15-3 per cent, and the bulk weight from 0.7- 1.5 kg/l. Alternatively, aluminium of 99.6 per cent purity, 0.22-.28 per cent iron and 0.12-.14 per cent silicon is first cast in strips of 10-15 cms length by dripping molten aluminium onto a centrifugal casting plate. The strips are then reduced in a round stamper with 0.4 per cent stearic acid to a size of 3.3 mm. A suitable stamper has twelve 45 kg. pestles of 90 mm stroke and a frequency of 80 strokes per minute, and produces 3.6 kg/hr. A further 0.4 per cent stearic acid is added and a similar stamper reduces the powder to a size of 0.7 mm at the rate of 4 kg/hr. The powder is next reduced to a size of 0.057 mm in a protective atmosphere in a ball mill having an inner diameter of 60 cms., a length of 3.5 ms, 6 longitudinal ribs, a speed of 38 r.p.m. and 1500 kg of steel balls of 5.6 mm dia. The powder is discharged pneumatically through a bronze screen. The output is 12 kg/hr. In a fifth step the powder is drystored for 4-8 weeks until the lubricant content has decreased to .35-.4 per cent. The powder is then ground for five hours in a ball-mill to a size of 0.035 mm. The powder is then sieved and stored 2-3 months after which it has a lubricant content 0.15-.2 per cent, an aluminium oxide content of 10-12 per cent and a bulk weight of 85 kg/l. Specification 373,784, [Group II], is referred to.

Abstract: 495,484. Control systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1937, No. 13971. Convention date, May 19, 1936. [Class 38 (iv)] Switching control; inductive control ; transformer arrangements.-The current to the electrodes of a resistance welding arrangement supplied from A.C. mains is effected by two " modulators " operating at different frequencies. Each modulator " consists of a transformer in which the coupling between the primary and secondary is varied and reversed continuously and cyclically by relative rotation. The transformer primaries may be connected in parallel across the supply with their secondaries connected in series with each other and with the primary of the welding transformer across the supply. Alternatively, the lower frequency modulator C has its secondary 6 in series with the welding transformer 11 across the supply mains whilst its primary 5 is supplied from the secondary 8 of the higher frequency " modulator " whose primary 7 is connected across the supply. The modulation frequency of one may be twice that of the other, the lower frequency " modulator " having a modulation of 150 per cent of the supply voltage whilst the other " modulator " has a modulation of 50 per cent of the supply voltage. By this means the R.M.S. voltage across the welding transformer is periodically reduced to zero 'for substantial periods. If desired, selected impulses may be cut out by contactor switches which open and close the circuit during periods of zero voltage. Specification 338,172, [Class 38 (iv)], is referred to.
