Title: Improvements in apparatus for obtaining connections in automatic telephony systems
IPC: H04M1/274
Filed: 1932-07-21
Abstract: 381,532. Impulse transmitters. BOY•, A., 9, Avenue de Villiers, Paris. July 21, 1932, No. 20641. Convention date, July 30, 1931. [Class 40 (iv).] Three selecting operations are necessary to effect the transmission of a seven-digit member of the form CEN2334, each operation selecting one of a hundred discs of which the first selected corresponds to the wanted exchange, the second to one of the digit pairs 00.. 99 representing the first two numerical digits, and the third to a similar digit pair representing the last two numerical digits. The apparatus produces a continuous stream of impulses, the selected discs splitting this up into the appropriate digits by short-circuits around the impulse springs. In the arrangement shown, the same hundred discs are used for the three selections, each disc c, Fig. 1, having an exchange designation and two numerical pairs on different portions of its periphery. Three pairs of shortcircuiting contacts 11, 12, 13, carried by sliders 14, 15, 16, are rendered operative in succession and at the appropriate times by a commutator 23. The impulse cam 9, disc assembly 3, and commutator 23 are driven through gearing from a shaft 4 by means of a spring 6 during the return movement of an external hand-lever 5. The slides 14, 15, 16 may be operated manually from outside the casing but in the arrangement shown in Figs. 3 and 7 they are driven from the shaft 4 through a one-way clutch 27, bevel gearing 28, friction clutch 32, pulleys 31, and a cord 36, the extent of movement being determined by push-buttons 42 one for each indication. Each slider head 16 carries a blade member 41 which is tilted by a depressed pushbutton into engagement with a stop 46 thus preventing further movement of the slider. During the setting of the sliders a triangular cam 48 on shaft 4 causes a rod 55 to tension a spring 57 and this is released to restore the shaft 30 and the sliders when the shaft 4 reaches its normal position. At the commencement of the return movement, the blade member which is unable to rotate by reason of the one-way coupling 39, 40 restores the depressed button to normal, and at the end of the return movement the withdrawal of pawl 40 by a projection 59 restores the blade member to normal. A screw 61 by locking wheel 56 and withdrawing pawl 27 permits any particular transmission to be repeated. In a modification three separate discs geared together and with correspondingly, spaced sectors replace each composite disc. c, and in a further modification three separate discs each having characteristic indications distributed over the whole circumference are driven successively.

Title: Improvements in and relating to wireless signalling systems
IPC: H04B7/08
Filed: 1921-08-05
Abstract: 188,082. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 5. 1921. Atmospherics and undesired signals, eliminating or limiting; heterodyne receiving systems.- Wireless signals are received on a number of widely-separated aerials connected by transmission lines to a central receiving-station, at which the received currents are adjusted in phase and amplitude and are selectively impressed on the receiver so as to give the most favourable stray ratio. As shown in Fig. 1, the aerials 1 - - 5 are coupled to transmission lines 6 - - 10 by which the received currents are transferred through adjustable couplings and phase adjusters 27 to a circuit including a receiver 28. One or more of the aerials mav be disconnected by closing switches 29 - - 32, and the couplings and phase adjusters are varied until the signal currents produce a cumulative effect in the receiver whilst the strays are in heterogeneous phase relation and are comparatively ineffective. In a modification shown in Fig. 2, a heterodyne source 16 is provided at the central station, and the local oscillations are sent out to the aerials along the lines 6 - - 10 and combine with the received currents, the resulting beats being detected by the detectors 11 - - 15 and transmitted to the central station over the lines 6 - - 10. By means of condensers 17, 23 and inductances 24, 25 the local oscillations and the beat currents are kept in their respective paths. Alternatively, as shown in Fig. 3, the local oscillations may be sent out over the two transmission lines in parallel with earth return, while the beat currents circulate in the closed circuit formed by the transmission lines. The frequency of the local oscillations may be multiplied by apparatus provided at each aerial, thus permitting the transmission along the line of a lower frequency. If this lower frequency is somewhat near the frequency of the beats, the arrangement shown in Fig. 6 may be employed for keeping the two currents separate. The source 16 is balanced as regards its effect on the receiver coupling 26 by connecting it to the mid-point of a coil and providing an artificial line 34 to balance the transmission line &c., whilst the frequencymultiplier 18 is isolated from the beat currents originating in the detector 11 by connecting it between equipotential points, an artificial line 35 being provided for this purpose. In a further modification, the heterodyne oscillations are radiated from an aerial provided at the central receiving-station and are received by the aerials 1 - - 5 jointly with the signal waves.

Abstract: 615,584. Heel-attaching machines. COPPOLA, A. July 15, 1946, No. 21159. Convention date, Dec. 12, 1939. [Class 17 (i)] A machine for attaching a heel by adhesive to a lasted shoe upper comprises a plate 7, on which the last is adjustably supported, and which is movable vertically on guide posts 5, under the action of a membrane 3 forming the top surface of a container 2 into which fluid under pressure may be admitted through a threeway valve 26. A second plate 11 carried by a screwed rod 10 is adjustable vertically relatively to the plate 7, by turning a handwheel 9 mounted on an upper plate 6 supported on the posts' 5. A pad 20 of the shape shown in the form of a metal block with a plate 22 pivoted at 23 to one side, is interposed between the plate 11 and the last on which the shoe is supported, so as to distribute the pressure evenly. Vertically adjustable members 13, 14, which support means which engage the heel and toe end of the last, are carried on a member 12 adjustable on the base plate 7. In operation, the shoe last is first adjusted in position on the plate 7 relatively to the screw 10, and vertically, by turning handwheels 17, the pad or block 20 is placed in position and the plate 11 brought to bear tightly on the pad 20, by turning the handwheel 9. Fluid under pressure, e.g. compressed air, is then admitted through the three-way cock 26 to cause the membrane 3 to bear on the plate 7 and raise it on the columns 5. A modified form of pad which may be substituted for the pad 20 when Louis XV heels are being attached is described. It comprises three arms each carrying rollers at their lower ends, which are screw-pressed against the action of springs and can be adjusted in relation to the sides and rear face of the heel before pressure is applied.
