Title: Improvements in or relating to telephone systems
IPC: H04M9/00
Filed: 1932-07-18
Abstract: 400,732. Intercommunication systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and JONES, A. F., c/o General Electric Co., Stoke, Coventry. July 18, 1932, No. 20273. [Class 40 (iv).] In an intercommunication system, the device whereby a disengaged station is informed of an incoming call also functions, when the station is engaged, to transmit an audible engaged signal to the calling station. The system described comprises master stations such as MA, Fig. 1, and ordinary stations such as SA, Fig. 3, similar to that described in Specification 354,043, the master stations being provided with the busy signal transmitting arrangements. A call from SA to MA is made by throwing SA1 which completes a circuit from battery CB, Fig. 1, MA1 (2), SA1 (3), Fig. 3, receiver SAR, SA1 (4), to relay A, Fig. 1, which completes a local circuit for buzzer BU. Lamp 7 also lights up in a branch circuit. On reply, MA1 is thrown to open the calling circuit and complete the talking circuit fed by battery TF. If, now, another ordinary station (connected to leads 16) calls the master station, a similar circuit for A is completed, but this relay closing contacts a1 before its other contacts, shortcircuits itself over MA1 (8) operated, and the resultant intermittent operation of A produces a tone in the receiver at the calling station. If another master station (not shown) calls by throwing a key corresponding to MAB, relay B is similarly operated and short-circuits itself over MA1 (8). The relays A, B may operate indicators, the buzzer BU being dispensed with. The tone transmitted by the relays may be varied by adding inductances, capacities or resistances to the circuits and they may function by opening their own circuits.

Title: An instrument for measuring the internal pressure and the loading of vehicle tires
IPC: G01L17/00
Filed: 1952-08-19
Abstract: 721,569. Pressure gauges. WILLINGER, R. Aug. 19, 1952 [Aug. 22, 1951], No. 20791/52. Class 106 (2). An instrument for gauging the internal pressure of, or the load on, a vehicle tyre comprises an upper arm B, Fig. 3, for contacting the tyre wall, a lower pivotally and slidably arranged arm C also for engagement with the tyre wall, and means, such as a flexible non- extensible band T connecting the ends of the arms, causing the lower arm C to contact the tyre wall always in substantially the same zone independently of the extent of the deformation of the tyre. The upper arm B is caused to contact the tyre wall under the tyre rim F at a point M which may be at a distance c from the axis x-y, whilst the lower arm C is caused to contact the tyre wall at a point N which may be at a distance k from the axis x-y. When the tyre is subjected to a load, Fig. 4, the points M and N remain unchanged with respect to the axis x-y due to the action of the band T on the pivoted and sliding lower arm C. The deformation of the tyre under load is transmitted to a pointer 20 moving over a scale S, such move. ment being caused by a drive from the lower arm C or a drive from a separate plunger 4 pressing against the flexible band T. In Fig. 5, the upper arm B is axially movable by being threaded in a sleeve manually rotatable by a knurled head 11. Before a tyre is subjected to a load, the apparatus is placed against the tyre as in Fig. 3, preferably in a horizontal plane through the centre of the wheel, and the knurled head 11 is turned until the pointer 20 indicates zero on the scale S with the plunger 4 just in engagement with the tape T. The turning of the head 11 also turns a scale E, Fig. 7, with respect to a mark m, the reading of the scale E, it is stated, being a zero setting of the apparatus for that particular tyre. When the tyre is subjected to a load and the apparatus is again applied thereto, in a vertical plane through the centre of the wheel, the deformation of the tyre causes the plunger 4 to be displaced to turn the pointer 20 through a string drive 25. The pointer 20 is held in its deflected position by brake means 7 until released by a push button 22 outside the casing. Fig. 9 shows a construction similar to that shown in Fig. 5 except that the pointer 20 is now driven by the movement of the lower arm C through gearing 40, 41 and a pulley drive 53.

Title: Improvements in or relating to current-measuring instruments
Inventor: WHITE BARRINGTON JOHN LEONARD
IPC: G01R15/18
Filed: 1960-06-17
Abstract: 912,721. Transistor amplifier circuits. DAWE INSTRUMENTS Ltd. May 29, 1961 [June 17, 1960], No. 21378/60. Class 40 (6). [Also in Group XXXVI] In an apparatus for measuring current in a conductor which is arranged as the primary winding of a transformer having two secondary windings the first secondary winding is arranged in circuit with the emitter of a transistor which constitutes the final stage of a transistor amplifier and a further secondary winding is arranged to provide feed-back of A.C. signals to the first stage of the amplifier. The primary winding may comprise a wire 3 (Fig. 2) carrying an alternating current to be measured around which may be clipped cores 1 and 2 carrying the secondary windings L1 and L2. These are connected in the circuit of Fig. 1 in such a way that the current flow in the winding L1 is applied as the input to the first stage VT1 of a transistor amplifier. This current is amplified through a further stage VT2 and thence to VT3 in the emitter circuit of which L2 is connected. The current through this winding is therefore increased, and the winding is so arranged as to produce a magnetic flux in the transformer core opposing that produced by the primary current. This causes the current through L1 and hence L2 to fall so that an equilibrium is set up sufficient to maintain a certain output from L1, and the overall effect is as though a negative resistance has been introduced at the base of VT3. The effect of this is to enable currents of low frequency induced in L2 down to 10 c/s., to be measured without appreciable loss (because resistive losses in L2 are counteracted by the current supplied to the base of VT3 by the amplifier). The measurement may be carried out using a valve voltmeter at the collector of VT3, or R8 may be replaced by a device of high impedance at the signal frequency, across which is connected a meter and rectifier system.

Title: Improvements in or relating to methods of manufacturing mosaic electrodes
IPC: H01J29/43
Filed: 1939-07-24
Abstract: 532,525. Cathode-ray tubes. BAIRD TELEVISION, Ltd., and SAMSON, K. A. R. July 24, 1939, No. 21411. [Class 39 (i)] In the production of mosaic electrodes, two or more metals are evaporated in succession on to a support to form a composite layer which is then heated in vacuo to cause the layer to break up into separate particles. The layer may be superficially oxidised before heating. According to one example, a layer of silver is evaporated on to a mica plate until the transparency is reduced to 30-40 per cent. Antimony is then evaporated on to the silver layer until the transparency is reduced to 5-10 per cent. The composite layer is broken up by heating in vacuo to between 400 and 500‹ C., and the mutually insulated particles photo-electrically sensitized as described in Specification 522,752. According to another example, the composite layer consists of an under layer of bismuth and upper layer of silver. The silver layer is oxidised, before heating, by electric discharge in an oxygen atmosphere, and the insulated particles may be sensitized as described in Specification 532,259.

Abstract: 217,470. Hodgson, J. L. Aug. 24, 1923. Elastic-diaphragm pressure gauges.-In gauges of the differential type the diaphragm is protected by stiff centres and by a cradle either on the low pressure side only or on both sides. In Fig. 1 the invention is shown applied to the gauge described in Specification 200,985. The diaphragm, which is provided with stiff centres P<1>, P<2> and conical cradles C<1>, C<2>, is controlled by springs S<1>, S<2>, and the movement is transmitted through the part E, roller R, crank K, and spindle G to an indicating needle. Pressure fluid is admitted through valves X<1>, X<2>, and' air vents V<1>, V<2> are provided, together with an equalizing valve not shown. The tension of the springs can be regulated by the nuts N<1>, N<3>, and the number of free turns in the spring S<2> can be varied by a threaded support W. The diaphragm is made preferably of rubber reinforced with fabric, and is shaped by weaving, stitching, moulding, or otherwise, so, that it can roll without stretching on at least the conical cradle on the low-pressure side. The joint between the diaphragm chamber and the outside air may be formed so as to grip the rim of the diaphragm, as shown in Figs. 2 and 3, so that a tight joint may be made at the rim of the diaphragm without disturbing the central portion. The rim of the diaphragm may be hardened or thickened: In the case of very high pressures a separate joint is made, as shown in Fig. 4, and a separate piece having formed on it the low pressure cradle gripping the rim of the diaphragm between it and the casing flange on the high pressureside.

Filed: 1953-08-04
Abstract: 741,340. Dashpots. PANTEX MANUFACTURING CORPORATION. Aug. 4, 1953 [Jan. 16, 1953], No. 21483/53. Class 108 (3). [Also in Groups VIII, XXIV and XXIX] Means for damping the opening and closing movement of the head of a garment press (see Group VIII) as it approaches its extreme positions, comprises a piston rod 71 having a piston 108 sliding in a cylinder 91 surrounded by an outer cylinder 87, the cylinder 91 having a series of openings 102 in its upper part and a valve 103 at its lower end. Ducts 81, 82 connected to the cylinders 87, 91 respectively are connected to each other through a check valve 84 and a hollow valve 135. As the press is being closed the piston rod 71 which is connected to a lever (not shown) carrying the press head is rising in the cylinder 91 and the piston 108 displaces liquid in the cylinder 91 through the openings 102 into the outer cylinder 87 and thence through conduit 81, valve 84, conduit 82 and valve 103 into the lower part of the cylinder 91. As the openings 102 are progressively covered by the piston 108 the outward flow of liquid is restricted and the closing of the press will be damped. As the press is opening piston 108 moves downwardly, liquid being displaced past valve 103, through duct 82, hollow valve 135, duct 81, cylinder 87 and openings 102. Near the end of its stroke a bore 123 in the piston 108 receives a bored conical member 106 carried by the valve 103 and restricts the flow of liquid therethrough, thereby damping the final opening movement of the press. As the piston starts its descent there is a free flow of liquid from the cylinder 87 through openings 102 into an annular space 110 in the piston and thence through a check valve 121 into the space above the piston. This check valve is closed during upward movement of the piston 108. The valve 103 is provided with a ring of openings 105 and is capable of limited axial movement. When the press is closed an increased pressure may be applied to the head through the piston 108 by opening a valve supplying air under pressure through a pipe 147 to a piston 143 whose plunger 144 engages and closes the top of the hollow valve 135. The plunger 144 depresses the valve 135 which is slidable against the action of a spring 136 and the liquid trapped between the valve 135 and the bottom of piston 108 will transmit an increased pressure to the press head.
