Patent GB-460343-A (GB)
Title: Improvements in or relating to weighing apparatus
IPC: G01G19/26
Filed: 1936-02-20
Abstract: 460,343. Automatic - feed weighers. BLAW KNOX, Ltd. Feb. 20, 1936, No. 5213. Convention date, Nov. 6, 1935. [Class 143] In a weighing - apparatus suitable for apportioning the ingredients of concrete and of the type wherein a number of ingredient bins each provided with a delivery gate, supply the ingredients successively to a weigh hopper, a plurality of counterpoise beams corresponding to the bins are provided and means operated by the opening of a gate is arranged to throw into action that counterpoise beam which governs the weight of material delivered through the opened gate. When the discharge door of the weigh hopper is opened all the counterpoise beams are thrown out of action and the delivery gates of the supply bins are locked in their closed positions. When one delivery gate is open the remainder are automatically locked in the closed position. As shown in Fig. 1, three ingredient bins 1, 2, 3 are provided, the bins 1, 3 being each divided into two bins 3a, 3b, Fig. 4, thus providing for five ingredients corresponding respectively to five counterpoise beams 12 ... 16. The counterpoise beams may be brought to bear individually, as described below, upon a ladder 20 coupled to a weighing beam 10. The weighing beam is connected to a dial 26, the pointer of which carries two electric contacts 28, 29 co-operating with a mercury contact 30. In weighing out one of the ingredients, for example from the bin 3b, the operator lowers a handle 38 loose on its shaft. A lug 40 on the handle rocks a bell-crank lever 41, 42 into the position shown in Fig. 4, and by means of a rod 43 rocks the delivery gate 36 into the open position wherein it is retained by a latch 47, the remaining gates being automatically locked against opening. A rope 69 is at the same time raised to overthrow a keeper beneath the corresponding counterpoise beam and allow the beam to bear upon the ladder 20. The pointer 25 in consequence moves from its zero. As the material enters the weigh hopper the pointer moves back towards its zero and the electric contacts 28, 29 successively touch the mercury contact 30 and by energizing a solenoid 31 connected to the latch 47 first allow the delivery gate to close partially and then entirely. The remaining ingredients are similarly weighed out and the operator discharges the batch by raising a handle connected to the discharge gate 6. On raising this handle a connection therefrom raises the keepers of all the counterpoise beams so as to render the counterpoise beams inactive and ready for the next weighing operation. When any of the delivery gates 36 are open a projection 63 co-operating with a locking yoke 95 prevents the discharge door of the weighhopper from being opened, and similarly prevents any of the delivery gates being opened unless the discharge door is closed. If the electrical mechanism fails, the latching mechanism 47 may be operated manually. U.S.A. Specification 2,040,703 is referred to.

IPC: C21B3/06
Filed: 1917-04-14
Abstract: 117,470. Herreshoff, J. B. April 14, 1917. Matte and collecting processes for copper and other metals.- Values are recovered from metallurgical slags by passing the slags through a series of baths of molten material containing a smaller percentage of the metal to be extracted than was originally present in the material from which the slag was separated. In the apparatus shown, copper slags from a smelting furnace 1 are passed into a series of tanks 2 - - 5 containing mattes of successively lower grades. The slag and matte from the tank 5 pass to a rotary mixer 7 by way of a trough 6 to which a lower grade of matte from a furnace 9 may be supplied. The slag and matte are afterwards separated in a tank 8. The low grade mattes are gradually enriched in copper and other metals and are transferred from time to time to the preceding tank of the series. The process may be similarly applied to the treatment of slags obtained in the extraction of other metal such as gold, silver, tin, lead, nickel, and cobalt.

Filed: 1944-03-24
Abstract: 581,416. Typewriters &c. WILLIAMS, W. P. (Standard Register Co.). March 24, 1944, No. 5511. [Class 100 (iv)] [Also in Group XV] In a manifolding apparatus such as an imprinting device in which superposed continuous record strips with sets of transfer sheets interleaved at intervals are advanced to the recording position, means are provided to arrest temporarily in such position one set of transfer sheets, and to cause the succeeding set as it approaches the recording position to release the first set so that it moves out of the machine with the record strips. The assemblage of record strips and transfer sheets employed is as described in Specification 581,415, [Group XV], and comprises a zig-zag folded pile of strips 5 in which are interleaved at suitable intervals sets of transfer sheets 13 loosely connected at their leading edges to one another and to the record strips by staples 15 and having attached to their trailing edges transverse strips 14 of thin relatively stiff material. The apparatus as illustrated has a pin-wheel feed, is provided immediately to the rear of the recording position 8 with two pivoted stops 10 held vertically by springs 11 so as to engage the projecting ends of the strips 14. When such engagement takes place, the movement of the carbon sheets 13 is arrested, but the strips 5 continue their movement causing the staples 15 to be torn away from the sheets 13. When a succeeding set of sheets 13 arrives adjacent to the recording position, its staples 15 engage the arrested strips 14 and by reason of the greater strength of the strips 5 force the strips past the stops 10 so as to allow the used set of sheets 13 to pass out of the machine and the succeeding set to advance to and be arrested in the recording position. Guide flanges 16 are provided to engage and restore to correct position any strips 14 which become displaced laterally. Specification 567,345, [Group VII], also is referred to.

In a subscription television system satisfactory reception by unauthorized receivers (i.e. receivers not equipped with suitable " decoding " apparatus) is prevented by replacing the horizontal blanking and synchronizing signals by a " grey-level " signal, the modified video signal being transmitted together with a " barker " signal (i.e. an audio transmission giving details of the modified video programme) as a modulated carrier wave and to enable satisfactory reception by authorized receivers a sine-wave signal having a frequency equal to that of the horizontal synchronizing signals is transmitted together with the normal sound signals and a D.C. operating potential over a wire link (e.g. telephone line or power cable) which is connected to each subscriber receiver in a metering device. Each of the latter receivers is provided with an attachment (which may be coin-freed) which, under the control of the sine-wave signal and the D.C. operating potential, reinserts the horizontal synchronizing signals in the modified video signal whilst it is still modulated on the carrier wave and thus provides a conventional video signal which may be satisfactorily reproduced by conventional receivers and, at the same time, breaks the normal audio circuit (which reproduces the " barker " signal) and connects it to the wire link over which the programme sound signals are transmitted.
