Title: Improvements in circuit arrangements embodying electron discharge devices
IPC: A61N1/40
Filed: 1940-08-01
Abstract: 540,400. Thermionic valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 1, 1940, No. 12467. Convention date, Aug. 1, 1939. [Class 40 (v)] A high frequency oscillator or amplifier is arranged in such a way that the anode and grid form opposite corners of a balanced bridge circuit, the other corners of which are the cathode and earth, the balance being effected by the addition of a condenser in one arm to match the stray capacities which constitute two of the arms. Fig. 1 shows a high frequency oscillator 11 in which the resonant circuit includes condensers 12, 13, 15 and a coil 14. The supply mains 16 feed a full-wave rectifier 20 which supply the anode and grid through impedances 22, 23 from a voltage divider 21. The oscillator is contained in an earthed casing 10 the stray capacities to which are shown dotted. The capacities 24, 25 between earth and grid and anode respectively form with condensers 12, 13 a bridge which if unbalanced would cause H.F. current to flow from cathode to earth which feeds back into the supply mains. This is overcome by the provision of a condenser 30 which is adjusted for balance as indicated by a lamp 31 failing to glow. An embodiment for a highfrequency amplifier is also described.

Title: Improvements in or relating to Magnetic Recording Systems
Inventor: JOHNSON WILLIAM EDWARD
IPC: G09B5/04
Filed: 1966-03-22
Abstract: 1,169,736. Magnetic record-teaching machines. W. E. JOHNSON, and M. S. STEELE. 25 May, 1967 [22 March, 1966], No. 12509/66. Heading G5R. A teaching machine comprises means for reproducing pre-recorded aural instruction items from a first magnetic record medium, means for selectively recording instruction items produced therefrom and/or aural responses thereto on a second magnetic record medium and for reproducing items from the latter repetitively at will, the machine having a common drive means for the first and second record media and selectively operable clutch means for coupling the drive means to either the first or the second record medium or to both at the same time. Preferably the second medium is provided by a short length of magnetic tape whose leading end is located between an extension of the master-tape capstan and a pinch roller reciprocable from an inoperative to a driving position. Thus a student may operate the supplementary tape alone to record and reproduce successively a number of responses to a single instruction item, or operate both tapes to record an instruction item on the supplementary tape for repetitive reproduction thereafter. The supplementary tape is preferably open-ended but may be a closed loop. Preferably the supplementary tape (feed) spool is spring-loaded or otherwise mechanically biased in the re-wind sense, so that the tape need be driven in only one direction by the capstan. The invention enables wear, by repeated reciprocation of localized regions of a single master- and student-track tape, to be avoided; undue wear of the main heads is also thus avoided.

Title: Ribbon drive apparatus
IPC: B41J33/22
Filed: 1974-03-22
Abstract: 1450249 Ink ribbon mechanisms TELETYPE CORP 22 March 1974 [27 March 1973] 12849/74 Heading B6F An ink ribbon mechanism for a line printer, in which one of the ribbon spool spindles 158, 160 is continuously driven by its respective gear trains 205, 277, 281, 279, or 205, 273, 271, includes sensing arms 185, 187 which detect an irregularity 321 adjacent the end of the ribbon 40 to reverse the ribbon feed so that a rack member 293 is moved from its horizontal position (Figs. 4, 7) to engage a gear of the gear train which is currently not driving its associated spindle. Figs. 4-7 (in that order) show how the drive is transferred from spindle 160 to spindle 158. As shown in Fig. 4 a button 321 on the ribbon 40 raises the arm 185 to the phantom position and so removes lobe 304a of the stop 304 from beneath the rack member 293. This permits the over-centring spring 295 to urge the rack member to engage gear 273 (see Fig. 5). As a result gear 273 rotates its mounting plate 243 against the action of spring 249 until complementary surfaces 243b, 245b no longer overlap (see Fig. 6) and gear 271 no longer engages gear 199 to transmit the drive to spindle 160. Further movement of the rack member 293 by gear 273 from the Fig. 6 position causes the spring 295 to rapidly move the member 293 and lever 291 to the Fig. 7 position in which the drive to the spindle 158 is effected and the rack member 293 rests on stop 302. Stop 302 will subsequently be moved by the sensing arm 187 detecting a button on the ribbon 40 so causing another reversal of the ribbon feed during which reversal the spring 295 completes one revolution to return to the Fig. 4 position.

Patent GB-132199-A (GB)
IPC: B61L3/22
Abstract: 132,199. Wilder, L. R. April 17, 1919. Wireless systems.-Apparatus actuating signals and train-controlling valves ie controlled by means of energy derived from a main wave wire and auxiliary wave wires disposed along the track. The sections of the main wave wire are connected through ir.ductances so as to prevent energization by leakage from the next block. The auxiliary wave wires are placed at the exit end of each block. Oscillating currents of differing high frequencies are supplied to the sections of the main wave-wire and to the auxiliary wave-wires for the two directions of traffic, and the supply of these currents is controlled by track relays. Fig. 2 shows the apparatus on the train comprising a collecting-harp 79 which is connected through contacts of the master relay 23 to either of the detectors 28, 38, which include pliotron valves 30 tuned to the frequency of the main and auxiliary wave-wires. Whilst the harp 79 is adjacent to an energized main wave-wire, the relay 23 is energized, and through its contact 71 the detector 28 is energized and relay 39 closes the circuit to relay 23. Armature 80 of this relay completes the circuit to the green lamp 63 and the whistle.-valve magnet 67, and armature 72 closes the circuit to the brake-valve magnet 70. When the harp passes over a section of main wave-wire which is de-energized on account of occupation of the section in advance, these circuits are all opened, the armature 80 puts the danger lamp 61 in operation, and the brake and whistle valves are opened. If an energized auxiliary wave-wire is then passed, the harp 79, being then connected by armature 71 to the detector 38, supplies current thereto, and the relay 48 re-energizes the relay 23, which causes the restoration of running conditions. A self-holding relay 86 may be energized by a push-button 83 so as to enable the driver to proceed while the danger conditions exist. The armatures 91 of this relay control the brake-valve magnet circuit.

Title: Manufacture of condensation products from urea and formaldehyde
IPC: C08G12/12
Filed: 1934-05-02
Abstract: Urea and formaldehyde are condensed in aqueous solution in the presence of zinc chloride with or without the addition of sucrose or phenol.  The proportion of zinc chloride used is preferably between 2 and 57 parts to 100 parts of urea and the temperature of reaction preferably below 212 DEG  F.  Useful products are obtained by stopping the reaction at an intermediate stage.  In an example, zinc chloride is dissolved in commercial aqueous formaldehyde and urea is added to the solution.  The solution is then passed through coils maintained at a fixed temperature and discharged through cooling coils to yield a very stable syrupy liquid.  The products may be converted into dry powder adhesives by drum or spray drying to yield a dry glue which, together with a little water is converted under heat and pressure to a strong bond.  The product dried on paper forms an adhesive softened by moisture, and sheet material such as wood veneer, insulating board, asbestos board, cloth, tissue paper and wire cloth soaked in or coated with the product may be dried and then laminated in a hot press.  It may be used as an adhesive for sticking leather or felt to rubber, as a lacquer or varnish, as a stiffener for textiles and composition sheets, as a waterproofing agent, as a base for films and film glues, as a binder for moulded products, as a base for cements and as a base for metal-cleaning and other polishes.ALSO:Condensation products of urea and formaldehyde in aqueous solution prepared in the presence of zinc chloride with or without the addition of phenol or sucrose may be used as adhesives.
