Title: Improvements in telephonographs
IPC: G11B25/02
Filed: 1920-07-02
Abstract: 147,555. Telegraphon Ges. July 17, 1919, [Convention date]. Tolephone signals and communications, recording and reproducing; cases; driving, starting and stopping; feed-motions; sound-boxes, raising, positioning, lowering, and arrangement of; mandrels. -A machine for recording and reproducing messages dictated directly or by telephone can be set to the various operative positions by depressing push-keys. The recording sound-box 12 and reproducing sound-box 13 are mounted at rightangles on a carrier 26 with the record cylinder 3 in the angle between them. The carrier 26 is mounted on a slider 27 which is raised and lowered by a nose 29 projecting from the shaft 18, so that one or other or neither of the sound-boxes will be operative, according to the position of the shaft. When one of the sound-boxes is operative, a nut member 24 on the stirrup 21 engages the feedscrew 17 which thereby traverses the sound-boxes, but when the shaft 18 is in the intermediate position with both sound-boxes disengaged, a cam 30 on the shaft depresses the stirrup 21 and disengages it from the feed-screw. The shaft 18 is turned to the required angular position by depressing one of the keys 41, 42, 43, 44. A blade 51 carried by the key thereupon engages an eccentric such as 53 on a shaft 52, and the setting of this is transmitted by linkwork to the shaft 18. Each key carries a set-screw 47 which on depression of the key engages a cam surface 49 formed on a sliding latch 45, and finally slips into the notch 49<1> so as to lock the key in position until another key is depressed. Each key on depression operates, a set of electric contacts, Fig. 11. The " Out of action " key 41 breaks at 62 the circuit of a motor or meter-controlling releasemagnet 8, the electric mains being connected .at 60. Each of the remaining keys closes contacts 61 to start the motor. The " Recording " key 42 breaks at 71 a contact which normally short-circuits the telephone line connected at 63. This key also closes at 70 the circuit of a magnetomicrophonic relay 65, which amplifies the sounds emitted by the telephone receiver 66 and effects the magnets 69 of the recording sound-box 12. The " Receiving " key 43, when an ordinary reproducer 13 is used, simply starts the motor at a speed reduced by the resistance 74. In the case shown however, the key closes at 76 the circuit of a receiver 75 in series with a. transmitter arranged in the reproducer 13. The " Dictation " key 44 closes at 73 the circuit of a transmitter 72. To facilitate the removal of records, one bearing 5 of the mandrel is mounted on a hoop 6 which is hinged at 7 to open outwards. This hoop and the door 82 of the case are locked by a sector 78 on the shaft 18, except when the apparatus is .in the " Out of action " condition. The keys 41, 42, 43, 44 are located outside the case which entirely encloses the rest of the apparatus.

Patent GB-839780-A (GB)
Title: Control means for automatically variable power transmission mechanisms on rail or road vehicles
Inventor: SUTHERLAND WILLIAM DRUMMOND
IPC: B61C9/12
Filed: 1957-06-14
Abstract: 839,780. Change-speed gearing. C.A.V. Ltd. July 25, 1958 [June 14, 1957], No. 18799/57. Class 80 (2). Electromagnets 1, 2, 3, 4 controlling the change-speed gear-box of a rail or road vehicle are operated automatically in accordance with speed by a vehicle-driven electric generator x through electromagnets f, g, h and relays c, d, e, time-responsive relays r, s, t, u ensuring predetermined time intervals between both upward and downward gear changes. With the vehicle at rest the system (for a four-speed gear-box) is in the condition shown, manual switches m 1 , m 2  controlling the gear-box and fuel pump(s), respectively, being open. To engage first gear switch m, is closed and current passes through switch c 2 , relay n and gear-change electromagnet 1; simultaneously switch n 1  is opened to put relay r out of action and allowing switch r 1  to remain closed. At the same time current through relays s, t, u causes charging of associated condensers sc, tc, uc and switches s 1 , t 1 , u 1  to be opened. When speed increases sufficiently for electromagnet f to operate, switch # 1  closes, speed relay c opens switch c 2  and puts first gear out of action; at the same time switch c 1  is closed, relay o energized, and switch o 1  opened. Reclosing of switch s 1  is delayed by discharge of condenser sc through relay s 1  at completion of which closure of switch s 1  enables electromagnet 2 to engage second gear. At still higher speeds electromagnets g, h operate in succession through relays d, e; p, q; t, u and electromagnets 3, 4 to engage third and fourth gears. With fall of speed the gear changes are effected in reverse order. With any one gear in use current in relay w (or in the appropriate one of alternative windings w 2 , w 3 , w 4 , w 5  associated with electromagnets 1, 2, 3, 4) holds switch w 1  open and interrupts current in relay v, so that switch v 1  remains closed and relay a is energized to close switch a 1  and energize electromagnet b to give normal fuel supply. During a gear change current flow first ceases in relay w to close switch w 1  and open switch v 1 , thus de-energizing relay a to re-open switch a 1  and de-energize electromagnet b and reduce fuel supply to idling rate. Upon completion of gear change switch w 1  re-opens and re-closes switch v 1  after a short interval during which condenser vc discharges through relay v, and normal fuel supply is then restored.

Title: Improvements in or relating to electrical heaters
IPC: G05D23/24
Filed: 1955-06-29
Abstract: 806,221. Automatic temperature control systems. IGRANIC ELECTRIC CO. Ltd. June 29, 1955 [July 2, 1954], No. 18802/55. Class 38 (4). In an automatic temperature control system, wherein a temperature-responsive resistor which may be the heating element is connected in one arm of a resistive bridge network energized from an A.C. source, a gas-discharge tube, controlling part of the energization of a heating element, has its anode connected to one side of the A.C. source and its grid-cathode circuit across the bridge output so that at the desired temperature the valve cuts off to reduce the heating element current. The heating element 10, Fig. 1, having a positive temperature coefficient for action as a detector, is connected with three zero coefficient resistors 12, 13, 14 in a bridge circuit energized with A.C. over lines L<SP>1</SP>, L<SP>2</SP>. A gas-discharge tube 15 has its anode connected to line L<SP>1</SP> through a variable resistor 16, and its grid-cathode circuit connected across the bridge output between points 17, 19. When the source is first connected, the valve conducts during half cycles of the source to supply additional current to the element 10; but when the desired temperature, as set by adjusting one of resistors 12, 13, 14, is attained, the valve cuts off to reduce the heater current. The valve thus cycles on and off to allow maintenance of the desired temperature, the resistor 16 being adjustable to vary the additional heater excitation with varying external conditions. In a modification, Fig. 2 (not shown), a half-wave rectifier is connected in series with the two parallel bridge paths across the A.C. source, so that the heater is only energized during the halfcycles in which the valve conducts. Both the above systems are said to be applicable to the temperature control of an electric blanket or a catalysing bath. In another modification, Fig. 4 (not shown), the heater has a zero coefficient and the resistor 14 a negative coefficient for action as the detector. Both heater and detector may be placed in an air conduit for maintaining of a desired air temperature. In a further modification, Fig. 3, with the same application, the heater 32 is not part of the bridge circuit but is energized over lines L 1 , L 2  in series with the load windings 33b of a saturable reactor 33. A detector 30 of positive coefficient forms one arm of the bridge, and a D.C. control winding 33c for the reactor is connected in parallel with rectifier 34 between the cathode of valve 15 and the bridge junction 17. The winding 33c remains energized until the valve cuts off at the desired temperature, when the increased impedance of the reactor load windings 33b decreases the heater current. Resistor 12 may constitute the detector in which case it has a negative temperature coefficient.

Title: Production of laminated bodies
Inventor: KIRCH ERNEST
IPC: B29C53/56
Filed: 1956-06-20
Abstract: 839,459. Compression-moulding laminated bodies. DIELEKTRA A. G. June 20, 1956, No. 19111/56. Class 87(2). A conical or cylindrical laminated body is made by a process in which sheet material is tightly wound on a mandrel to form a dense coil which is heated to soften plastic carried by the sheet material and is simultaneously compressed edgewise in, and in contact with, the cylindrical or conical bore of a mould which prevents a radial expansion and rupture of the sheet material so that the coil is compacted with the planes of the laminations substantially parallel to the surface of the bore into a body which is rigid on cooling. The material, e.g. a resin-impregnated coil of paper, is placed in a steel tube, forming the mould, and a steel core is placed inside the coil. The mould may be preheated. At a temperature at which the resin is fluid pressure is applied to the coil at one or both ends, the sheet layers forming into small folds, aided by the lubricating effect of the resin. By using a sectional core, with a reduction in diameter in its length, tubes may be moulded with projections on their inner walls, extra material being added if necessary ; metal inserts may also be moulded in. To mould a tube grooved on its outside, grooves are cut on the coiled tube before it is placed in the mould and wire is placed in them. A metallic or semi-conductive layer may be included to give a condenser bushing construction, rods may also be formed, and the section may be variable. To make a tube having large and small diameters, e.g. a shield 19 for an electrode, Fig. 7, the mould 1 and core 2 are suitably shaped, a steel ring 21 is fitted in the smaller annular bore, the impregnated coil is placed in the larger annular space, and the axial pressure is applied by a member 20 which fits into this space. The outer diameter of the tube may be the same throughout, the wall being thicker at the smaller inside diameter. Two tubes may be joined end-. to-end by placing them in a mould with their ends abutting and applying axial pressure, and they may be of differing electrical conductivity. Other suitable sheet materials are foil coated with synthetic resin such as cellulose triacetate, foil coated with a self-adhesive compound, uncoated thermoplastic foil, woven glass carrying plastic, mica flake synthetic resin laminate. The plastic may be a thermosoftening synthetic resin, unset thermohardening synthetic resin, or a natural resin of low electrical conductivity such as shellac.
