Title: An improved modulator and demodulator arrangement
Inventor: HANNEWALD ERICH
IPC: H03C1/58
Filed: 1955-06-09
Abstract: 814,894. Amplitude modulation systems. FELTEN & GUILLEAUME FERNMELDEANLAGEN G.m.b.H. June 9, 1955, No. 16572/55. Class 40 (5). In a modulator having rectifying elements in push-pull or double push-pull connection the slope of the carrier voltage curve, particularly near its zero points, is altered to reduce undesired modulation products f c Œ3f m , where f c , f m  are respectively the carrier and modulation frequencies. This is done by a resistor in series with the carrier source and either a capacitor c shunting the resistor and carrier source or small capacitors shunting each of the rectifiers, so that the slope of the carrier voltage curve decreases as the rectifiers become conductive (due to the changing in carrier phase across the condenser). Alternatively the carrier may have superimposed on it one of its harmonics of selected amplitude and phase. The modulator may reversely act as a demodulator.

Title: Improvements in remotely controlled electrically operated point apparatus
IPC: B61L5/06
Filed: 1950-07-05
Abstract: 700,354. Switch point control. ABBEY, A. (Soc. Technique pour L'Industrie Nouvelle Soc. Anon. Stin.). July 5, 1950, No. 16775/50. Class 104 (1). A remotely controlled electrical pointoperating apparatus has the contacts of the control switch, indicator relays and the control relays which are located in the battery changeover relay coil arranged between the battery changeover relay coil and the point control relay coils. A changeover-switch H is arranged at a distance from or comprises a contact in a relay of the apparatus. The position of the points is controlled by relays st1 and st2, and contact st12 and st22 of these relays lie in the circuit of two points-position-indicator relays U1 and U2. The relays U1 and U2 are deenergized during the point changing operation by the opening of a contact k1 of a supervisory relay K, and when the point has changed over the relay K is energized and one of the relays U1 or U2 is energized through the contacts st12 or st22 to indicate the position of the points. The relays st1 and st2 are-mechanically interlocked so that only one can be operated at a time. When one relay st1 or st2 is operated its contacts st11 or st21 are closed so as to permit energization of the other relay st2 or st1. A battery changeover relay B and the supervisory relay K which lies in the supervisory circuit of a point actuating device WA are mechanically interlocked so that if relay B is operated while the relay K is unoperated, the relay B is de-energized and is held in its operative position until the relay K is operated. The relay B then assumes its unoperated position until re-energized and the relay K on de-energization assumes its unoperated position even if the relay B is in its unoperated position. Since one terminal of each control relay st1 and st2 is connected to earth and the coil of the battery changeover switch B is connected to the battery, the point control relays and the battery changeover relay cannot be energized simultaneously through extraneous or earthing currents.

Abstract: 562,979. Coin-freed meters. CROMPTON PARKINSON, Ltd., and ANGOLD, A. W. Nov. 27, 1942, No. 16879. [Class 27] In a prepayment meter where a coin is gauged in a pocket to allow quantity to be preset for delivery proportionate to the coin value, for example, as described in Specification 515,223, the displacement of a member to free the slot for insertion of the coin sets an injector for sweeping the coin into the mechanism. A movable jaw 6 must be slid down to allow a coin to enter and carries a roll 18 down against the cam faces 23, 23a, 23b of a lever 21, pivoted at 22 so that it moves a pin 27 on a coin injector lever 25, pivoted at 26, causing the injector to rise from the position shown in which it obstructs the way to the gauging pocket 2 to an upper position. A coin of the proper size passes thus between the lever 25 and the jaw 6, and the spring 19 then returns the jaw upwards striking the roll 18 against a second cam surface 24 and causing the lever 25 to throw the coin onward into the gauging pocket. The position and length of the lever 25 are such as to obstruct the passage of too small a coin. The spaced parallel plates 9 forming the sides of the outer coin pocket 1, and the lever 25 are made of non-conducting material,

Class 38(5) The moving contact is carried by one end of a rigid arm and is connected by a rigid compression member with the operating member. the moving contact being urged towards the operating member by a resilient member, so that movement of the .operating member first causes the contact to move away from the operating member and then to engage or disengage a fixed contact. In one form the contact 3 is mounted on a U-shaped arm 4 connected at 9<SP>1</SP> to a spring 10 urging the arm to the left, thus holding a member 12 in compression between the contact 3 and a groove 8 in a dolly 7. The latter may pivot about the end of an anchor piece 16 on which the spring 10 is mounted, or on a pivot pin. The contact 3 co-operates with fixed contacts 1 2, although contact 2 may be replaced by a stop. The contact 3 is connected by a flexible conductor 5 to a terminal 6 so that the other switch parts may be of insulating material. Movement of the dolly initially causes a movement to the right of the arm 4 and contact 3 so as to clean the contact surfaces, the mechanism then moving across dead-centre to open or close the contacts. In a modification, the contact arm is curved to pass between the dolly and the base and is formed at its mounting end with a hole in which is located a sinuous blade spring urging the arm to the left. According to the second Provisional Specification, the sinuous blade spring is replaced by a coiled compression spring. The operating member in either embodiment may be a push-pull member.
