Abstract: 937,298. Automatic feed weighers. ELLIOT BROTHERS (LONDON) Ltd. Jan. 21, 1960 [Jan. 21, 1959], No. 2208/59. Class 143. The ingredients of a mixture are weighed into separate containers, the feed to each of which is independently out off on the attainment of a predetermined batch weight of the corresponding ingredient, all the ingredient feeds not previously cut off being simultaneously cut off when the contents of all the containers together attains a predetermined total batch weight. The individual containers are then emptied into a common receptacle. The apparatus incorporates a master weigher comprising a weigh beam 1 which carries a depending post 4 supporting a platform 5 which in turn carries the ingredient weigh beams 6. These are eighteen in number and are equally spaced around the circular periphery of the platform 5. Each beam 6 carries a hopper 11 fed from a bin 14 by a vibratory feeder 13 and closed by a door 12. In use, up to seventeen of the hoppers 11 are fed until their beams 6 tilt and in so doing break switches which stop their associated feeders. When the master beam 1 tilts it opens a switch stopping all the feeders and also actuates a solenoid 15 to release, by levers 16, all the hopper doors 12 so that the batch enters a waiting container 18. If the main beam remains untilted when all the feeds have been cut off, a make-weight ingredient is fed to the spare eighteenth weigher until beam 1 tilts. The discharge controlling solenoid is prevented from operating if no container 18 is present.

Title: Improvements in or relating to prepayment mechanisms
IPC: G07F15/06
Filed: 1933-01-24
Abstract: 414,069. Prepayment mechanism for meters. BUTHERUS, F. R., and BRITISH SANGAMO CO., Ltd., Cambridge Arterial Road, Enfield, Middlesex. Jan. 24, 1933, Nos. 2304 and 5010. [Class 27.] In prepayment meter mechanism in which rent or other fixed charges is collected by a constant speed motor 1, the motor 1 through gearing 3 and pawl and ratchet gearing 5, 6 drives continuously a shaft 4 having fixed to it an arm 10 provided with a driving pawl 11 which engages the teeth of a ratchet wheel 9 and drives this through part of a revolution only, the period during which driving takes place being readily adjustable so that the amount of fixed charges collected is easily varied. The wheel 9 is in one with a braking wheel 8 engaged by a spring-pressed ball 106, and with a gear-wheel 7 from which the motion is transmitted through gearing 26, 29 and an arrears mechanism to one sun wheel of an epicyclic mechanism, the other sun-wheel being rotated after the insertion of a coin. The action is such that the constant speed motor returns the quantity mechanism which is set forward by a coin. The pawl 11 is normally held out of engagement with the wheel 9 by a spring 13, but during rotation an extension 17 thereon engages a fixed pin 19 to cause driving engagement. The wheel 9 is then driven until another extension 18 engages an adjustable pin 22. The pin 22 is on an arm 23 carried by a ratchet wheel 24 which can be turned by a screw-driver inserted in a slot 87 to a position corresponding to the fixed charge to be collected, which is indicated by markings on the wheel face. The shaft 4 may be rotated manually by a knob 88 through gearing 90, 91, to test whether the pawl 11 is correctly actuated by the pins 19, 22. A shaft 92 extending through the front plate of the meter and provided with a dial 94 is driven continuously by the motor 1 through gearing 93 which is chosen so that the dial 94 makes one complete revolution per hour if the motor 1 is working at its proper speed. This tests the speed of the motor. The shaft 4 through gearing 26, 27, 96, 97 drives a dial 98 graduated in pence per week. The gearing is so chosen that in a short period, say two hours, the dial indicates the amount of fixed charges collected in a week. Specification 347,794 is referred to.

IPC: H04N5/073
Filed: 1953-01-28
Abstract: 749,592. Television. PYE, Ltd. Jan. 26, 1954 [Jan. 28, 1953], No. 2446/53. Class 40-(3). Change-over of synchronization from a local to a remote source, e.g. a remote camera, or vice versa, is arranged, by a coincidence gate G2, to become effective only when two trains of synchronizing pulses from the sources become coincident in timing. An electronic switch 70A, 70B (bi-stable circuit) passes either one of the two pulse trains through alternatively open gates G1, G2 with common output amplifier 73, dependent on the selected position of a changeover switch S7 connected between either of the inputs of the switch 70A, 70B and the coincidence gate G2. The remote synchronizing signal and local (phantom remote) line pulses are applied to line pulse separator and differentiating circuits 60, 68 respectively to produce short duration pulses fed to the coincidence gate G2, and alternatively the remote or local pulses from the common amplifier 73 are fed to the line synchronizing circuit A. The switch S7 may be ganged to a switch S5 in the frame synchronizing circuit B so that either remote or phantom, i.e. local, frame synchronizing pulses are applied to the frame synchronizing circuit. The local frame pulses are derived, through a frequency divider and flip-flop 65, from a local master oscillator 63 of twice line frequency and a switch S8, ganged with the switches S7, S5, may connect a small capacitor to the oscillator 63 to vary temporarily its frequency so that synchronization is more quickly obtained. Specifications 749,573 and 749,591, [Group XXI], are referred to.

Title: Interface circuit
IPC: H03K19/018
Filed: 1973-01-17
Abstract: 1455571 Interface circuits for TTL and MOS logic NATIONAL RESEARCH DEVELOPMENT CORP 8 March 1974 [17 Jan 1973] 2477/73 Heading H3T In an interface circuit the collector of a transistor 25 is connected to the bases of transistors 27 and 28 of opposite conductivity type so that an input at 23 to the base of transistor 25 causes a terminal 22 connected to the emitters of 27 and 28 to be connected to one reference potential +V or via a resistor 29 to another reference potential and the p.d. across the resistor 29 switches on output terminal 24 of a switch 30 to one or other voltage levels. The interface circuit can be used to couple the output from TTL circuit connected to 23 to the input/output connection of a MOS logic circuit connected to 22. The output from the MOS logic at 22 is then coupled to the input of a TT logic connected to 24. In the '1' logic state of the TTL the TTL output at 23 is +W, transistors 25 and 28 are conducting and transistors 27 and 30 are cut off. With no current flowing through 22 the input/ output terminal 22 of the MOS logic is slightly greater than 0 and the input to the TTL logic from 24 is W+. In the '0' logic state of the TTL the TTL output at 23 is 0, transistors 25 and 28 are cut off and transistor 27 conducts to make the input/output terminal 22 of the MOS logic nearly +V. If, when the TTL is at logic 1, current flows from the MOS logic output to 22 then current flows through the conducting transistor 28 and turns on the transistor 30 to make the input to the TTL at 24 go to 0 indicating a '0' logic level. By connecting a resistor in the base circuit of the transistor 30 the maximum capacitive load which the interface can drive may be increased. The time performance of the circuit can be improved by strapping diodes across the collector-base junction of transistor 25, 28 and 30. In a modification (Fig. 3, not shown) the transistor 30 and resistor 31 are replaced by a differential amplifier 60a. In a further modification (Fig. 4, not shown) two circuits each including the components 21-23 and 25-29 are fed with differential MOS logic input/output connections (62, 72) to their associated terminal 22 and the potential differences across their respective resistors (69, 79) corresponding to resistor 29 are fed to a differential amplifier (82).
