Title: Improvements in or connected with electric secret combination switches for preventing the theft of motor vehicles
IPC: B60R25/04
Filed: 1933-03-17
Abstract: 416,512. Secret contact-combination switches. RENNIE, J. A., 118, Fleet Street, London. March 17, 1933, No. 8172. [Class 38 (v).] A secret combination switch for a motor vehicle, when set closes the circuits to the sparking plugs and prepares a circuit to the motor starter ; rotation of a switch making the ignition effective then locks the combination switch and moves a shutter so that the combination cannot be read; reverse rotation of the ignition switch to stop the engine unlocks the combination switch and automatically disarranges it and moves back the shutter. The combination switch comprises discs 1, 2, 3 carrying real and dummy contacts 1<a>, 2<a>, 3<a> and operable by numbered discs 4, 5, 6. Each disc 1, 2 or 3 carries a number of real contacts equal to the number of cylinders of the engine and they are irregularly arranged on the disc. The discs 1, 2, 3 also each carry a single contact 10, the three contacts 10 engaging each other when the combination is set and then serving to bridge two fixed spring contacts 14, 15 in the starter circuit. The ignition switch comprises a spindle 21 rotatable by a handle 28 and carrying a contact member 32 adapted to engage fixed contacts (not shown). The spindle 21 also carries a cam 33 adapted to press fingers 16 into recesses in the peripheries of the discs 1, 2, 3 so as to lock the latter. Mounted slidably but not rotatably on the spindle 21 is a rubber wheel 22 which tends to move to the left under the influence of springs 26 but is prevented, in the position shown, by the engagement of cam projections 23 on the wheel with cam projections 24 on a disc 25 which is free to rotate through a limited angle. On rotating the spindle 21 to make the ignition effective, the members 22, 25 rotate together till the disc 25 can rotate no further. The rubber wheel 22 rotates slightly further, the projections 23, 24 slipping off each other and the wheel 22 coming into contact with the three operating discs 4, 5, 6. Reverse rotation of the spindle 21 then causes derangement of the discs 4, 5, 6, the wheel 22 pushing the disc 25 round with it until near the end of the stroke when the projections 23, ride up over the projections 24 and the original position is reached. The shutter 37<a> concealing the combination is actuated by a link 41 engaged by a finger 43<a> on the shaft 21.

Title: Improvements in or relating to materials and processes for producing chemical coatings on the surfaces of corrosion-resistant metals and alloys
IPC: C23C22/46
Filed: 1960-03-08
Abstract: An aqueous acid solution for chemically coating corrosion resistant metals and alloys such as nickel base alloys and stainless steels, consists of the oxalate anion and cation, the borate anion and cation, and a sulphur bearing compound which yields sulphur dioxide and sulphur upon decomposition in acid solution.  Oxalic acid and boric acid are the preferred sources of the oxalate and borate ions but the sodium, potassium and ammonium salts may also be used, in which case a mineral acid such as sulphuric, hydrochloric, nitric or phosphoric acid is added to reduce the pH of the solution which should be between 0.5 and 2.5. The sulphur compounds used are the water soluble thiosulphates, sulphites, thionates, and hydrosulphites in an amount sufficient to give a titration limit of 2 to 15 mls. of 0.05 N iodine solution for a 10 mm. sample of the solution.  The solution contains 0.1 to 4 parts by weight of boric acid per part of oxalic acid which is present from 2 to 500 gms per litre, and it may be prepared or replenished with a dry powdered mixture of boron trioxide and commercial grade oxalic acid which may also contain the sulphur compound, the dry mixture having the following composition by weight, 5% to 47.5% boron trioxide, 10% to 70% oxalic acid and 5% to 80% sulphur compound.  The solution is maintained at 120 DEG F. to 180 DEG F. during the coating process and the surface to be coated may be activated prior to coating.

Title: Arrangement for inductive signalling between locomotive and track apparatus
IPC: B61L3/12
Filed: 1936-03-19
Abstract: 473,759. Inductive signalling between train and track. VEREINIGTE EISENBAHN-SIGNALWERKE GES. March 19, 1936, No. 8264. Convention . date, March 30, 1935. [Class 105] Apparatus for signalling between train and track comprises an inductive system on the track and an inductive system on the train, one system having a pair of circuits so arranged that electromotive force induced by the power flux of one circuit into the other circuit is cancelled by an opposing electro-motive force, and the different signals being given according to the phase of the reaction current induced from one system into the other system. As shown a multiphase generator 40 has one phase 44 feeding a circuit comprising windings 55, 56 on a train core 57 which co-operates with a track core 17. The train core 57 also carries windings 62, 63 which control the grids of gaseous discharge tubes 50, 51 the anodes of which are connected through relays 53, 52 with other phases of the generator 40, the anode of tube 51 actually being fed by a rotary phase shifter 45 which is automatically operated in accordance with the speed of the train. The train-core windings 55, 56, 62, 63 are such that the electromotive forces induced in the windings 62, 63 by the flux from the current in windings 55, 56 balance out and thus such current does not affect the grids of the gaseous discharge tubes 50, 51. When however the train passes over a track core a reaction current is produced in the windings 62, 63. The phase of this reaction current is determined by the inductance, condenser, and resistance members 18, 19, 20 and may cause one or other or both of the tubes 50, 51 to become conductive and so operate (for example, de-energize), one or other or both relays 53, 52. The condition of the track-core circuit 18, 19, 20, 22 is determined by the wayside signal and the tube 51 being under control of the speed-controlled phase shifter 45 responds only under certain conditions of speed. Grid-bias potential for the tubes may be given by the balancing- out effect between the windings 55, 56 and 62, 63 being made incomplete or by providing rectifier-and-resistance units 58, 59 and 60, 61.

Title: Radio communication system
IPC: H04W48/16
Filed: 1974-02-25
Abstract: 1423972 Connecting high frequency subscribers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Feb 1974 [28 Feb 1973] 8376/74 Heading H4K In a radio communication system a scanner at each station scans during idle periods the frequency channels of the system and a record is kept in the respective station, for each channel, of the number of scans that have occurred since activity in the frequency channel was last detected, the record providing a basis for communication channel selection. In an idle station, a synthesizer 3 sequentially generates the carrier frequencies of the system under the control of a code generator 5 and a channel selection device 6, and supplies the frequencies in turn to a receiver 2 which is coupled to a signal detector 8 for detecting the presence of scanned frequency and to a busy detector 9 which indicates the presence of a busy signal modulated on the scanned frequency. An output from the detector 8 causes a counter associated with the scanned frequency to be reset whereas the absence of an output causes the counter to increment by 1. The detection of the busy signal causes a busy indication to be stored for that frequency, and provides for a distinction to be made between a busy frequency and the presence of the frequency due to interference or jamming from outside the system. In the case of an output from detector 8, a check is performed to determine whether a code indicative of the station is present, the detection of which causes an indication of an incoming call to be given. When an outgoing call is initiated, the station circuitry examines the counters associated with the frequency channels, and the channel registering the longest free period may be selected. Alternatively the channel with the third longest free period may be selected as the one least likely to be interfered with or jammed during the setting up of the connection; several other selection criteria are discussed. The busy signal is supplied to the frequency channel by a device 4 in the calling station and simplex communication, is used. If all channels are detected a lamp is lit at the station (no free channels available).
