Abstract: 400,636. Prepayment mechanism for meters. UNITED GAS INDUSTRIES, Ltd., 51, Lincoln's Inn Fields, SMITH, E. W., 186, Kennington Park Road, and CHARLES, A., The Meter Works, Rowan Road, Streatham Vale, all in London. March 23, 1932, No. 8658. [Class 27.] Coin action, mechanicalconnection; multiple coin. -Coin - actuated mechanism for gas and like meters. particularly of the kind described in Specification 392,530, is adapted foi alternative actuation by two different coins, and comprises separate and adjacent coin slots and separate strikers for actuation by the respective coins, the striker corresponding tc the coin of smaller value being independently operable while the striker for the coin of higher value when actuated causes also the actuation of the first striker. The mechanism comprises a price-changing disc a carrying a cylindrical casing j within which is mounted a disc b rotatable by a handle c. The disc b carries, substantially diametrically, a coin holder comprising a plate e and a plate parallel thereto, between which are mounted slidably and in the same plane strikers f, g of the form shown in Fig. 4. The striker f carries a transverse member f<3> which is formed with an upstanding flange f<4>, and rests on a slightly wider transverse member g<4> extending the whole width of the coin holder and carried by the striker g. A pair of slots is formed in the disc b adjacent the end of the coin holder for coins of different value, for example a penny and a shilling, and corresponding slots are formed in the disc a. When a penny is inserted, it passes into the space between the flange f<4> and the wall of the coin holder, and engages the member g<4>, thereby depressing the striker g against the action of a spring g<3> and causing it to engage a quantity wheel i, which may now be rotated by turning the handle c. At the end of the operation the penny, which is pressed against the inner wall of the casing j, reaches a discharge slot therein and is ejected by the spring, the member g simultaneously being disengaged from the wheel i. A shilling passes between the flange f<4> and the striker f, and engages the member f<3>, thereby depressing this striker and causing it to engage a quantity wheel h; simultaneously the striker g is depressed by the engagement of the member g4 by the member f<3>, so that in this case both quantity wheels are rotated. The flange f<4> is preferably bevelled as shown on its inner face, so that as the coin holder rotates, the outer edge of the shilling, by its frictional engagement with the inner surface of the casing, is moved over and caused to assume the same position as the edge of a penny, discharge thus taking place after the same degree of rotation has been effected in both cases.

Abstract: 690,453. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 16, 1951 [April 19, 1950], No. 8825/51. Class 40 (iv). A group selector controlled by marking from a common circuit has no normal position and has the outlets of each numerical group evenly distributed over its bank. As shown, the common circuit CC1 is multipled to a number of group selectors GK and is associated with one of them by relay E, all the selectors being busied while the common circuit is in use. The digit switch DS is set by impulses, and dialling relay O energizes at the first impulse followed by M. The relapse of O completes the driving circuit for the selector, M being held, and the marking circuit including test relay T for all the outlets of the required group. Relay T energizes an an idle outlet, cuts the drive and operates switching relay H. The selector is intended to be used in a direct-dialling system and its speed may be such that all the outlets of a group can be tested in the pause before the next impulse train. If, however, a fresh impulse arrives before the selector is set, ground is connected to the b wire in order to give a busy signal.

Abstract: 633,369. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. April 1, 1947, No. 8887. Convention date, Feb. 15, 1946. [Class 40 (vi)] A circuit, comprising a regenerative frequency divider, for producing a wave having a frequency which is a harmonic of a sub-harmonic of an input wave is caused initially to selfoscillate at the sub-harmonic frequency in order to start the operation of the divider. A triode-hexode valve 1 mixes a fundamental frequency F derived by operating the triode section as a crystal oscillator with a heterodyne wave derived from lead 3 and which differs from the fundamental by a sub-harmonic frequency. The difference frequency (which is equal to the sub-harmonic) is filtered by transformer 4, amplified in valves 5 and 6 and applied through a band-pass filter 8 to a frequency multiplying rectifier bridge 9 to produce the heterodyne frequency. This is applied to the output terminals 11 and also to filter 16, the output of which is amplified in valve 17 and applied to the mixer through lead 3 as described. To start operation of the circuit, valves 5 and 6 are caused to oscillate at the sub-harmonic frequency by feedback connection 14, 15 which is, however, broken when a sufficient output is developed across the multiplier bridge to operate a relay 12. U.S.A. Specification 2,159,595 is referred to. The Specification as open to inspection under Sect. 91 describes also an arrangement in which the relay operates a further relay which intermittently earths the anode of the amplifier valve 6 to cause the generation of a starting oscillation by shock excitation. This subject-matter does not appear in the Specification as accepted.
