Title: Improvements in or relating to mixing condensers
IPC: F28B3/02
Filed: 1961-06-14
Abstract: <PICT:0935198/III/1> <PICT:0935198/III/2> <PICT:0935198/III/3> Vapours are condensed by bringing them into direct contact with films 5 of cooling-liquid flowing down vertical plates 4 spaced apart so as to form channels through which the vapours are passed in a horizontal direction.  Narrower cross-section of flow is obtained at the vapourdownstream end of the condenser by inserting additional plates 4a.  In order to condense steam, water is used as cooling-liquid. The plates may be smooth, perforated or corrugated.  The cooling-liquid is supplied to the condenser through inlet 1, and then flows on to the plates through slots between guiding-inserts 3.  The mixture of condensate and cooling-liquid collects in sump 10 and is withdrawn through outlet 11 The mixture of non-condensed vapour and air is exhausted through outlet 7.  In some cases, it is advantageous to use an assembly of plates with channels which narrow gradually in the direction of vapour-flow.

Title: Improvements in carcass dehairing and cleaning machines
IPC: A22B5/08
Filed: 1921-08-16
Abstract: 184,378. Schmidt, O. C. Aug. 16, 1921. Carcases, treating.-In a machine for dehairing and cleaning carcases, the scalded carcases are received on spaced plate-like members 15 which alternate with rotary beaters or scrapers which project beyond the supporting-surface, the carcases being raised by each scraping-arm and thereby deriving a rotary motion, which presents all surfaces to the scrapers, and a motion which contacts the carcases with the portions 17, 18 of the member 15. The portions 17, 18 are set obliquely, Fig. 3, so that the carcases are advanced towards the discharging point or are deposited directly on the finishing bench. The advance may be retarded by bringing hinged rods 36, opposite oblique, into contact with the carcases. The scrapers comprise a central rigid spider 27, mounted on the shaft 25, and flexible beaters 28 with scrapers 29 attached thereto. The members 15 are cut away at 45 to receive the shaft 25 and the scrapers extend beyond the median plane to scrape portions of the carcases remote from the shaft 25. Water may be sprayed on the carcases during the dehairing.

Abstract: 171,412. Siemens - Schuckertwerke Ges. July 21, 1919. Alternating-current motors; rotary converters; field magnets, dampers and short-circuited screens on poles of; pole-pieces.-Synchronous alternating- current motors with projecting poles and auxiliary windings for asynchronous running are so constructed that the ratio between the pole arc and pole pitch is greater than 0.8. The auxiliary winding may be wound as a phasal winding shortcircuited over a starting resistance in the ordinary manner and acting as a damping winding when the machine runs synchronously. Such machines are stated to run synchronously with normal torque and, in the event of their dropping out of synchronism, they run as asynchronous machines up to a certain load. In the form shown, the pole 11 of a synchronous machine has a continuous-current winding 12, practically uniformly distributed slots 16 for an auxiliary winding, and a, pole are 15 which is greater than eight-tenths of the polar pitch arc 14. The Specification, as open to inspection under Sect. 91 (3) (a) mentions the application of the invention to single-armature converters. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in prepaid meters
IPC: G07F15/04
Filed: 1933-08-04
Abstract: 426,709. Prepayment mechanism for meters. WHITE, W. H., c/o English, Scottish & Australian Bank, 5, Gracechurch Street, London. Aug. 4, 1933, No. 21937. [Class 27] Coin-action, mechanical connection with delivery proportionate to value of coin. - Inserted coins couple a manually operated member with a member connected to the quantity mechanism, and individual guides of differing length for supporting the coins in coupling position are provided for each coin so that the quantity mechanism is set forward by an amount appropriate to the value of an inserted coin. The construction shown is operable by any one of three coins, and comprises an apertured disc 13, which is rotated by a manually operated plunger through ratchet and pawl mechanism, and a slotted disc 27 operatively connected with the quantity mechanism, the two discs being journalled in a fixed plate 51 having spiral guide grooves 50 of differing lengths in its upper face for supporting the coins in coupling position between the discs. The different coins are inserted through separate slots 4, 5, 6, and are directed by separate shoots into coupling position at the commencement of the appropriate guide groove. As the disc 13 is rotated, its motion is transmitted to the disc 27 through the inserted coin which travels edgewise along its groove until it falls through a discharge opening therein, so breaking the connection. Coin-slit closing devices.-The insertion slots 4, 5, 6 are normally closed by a slotted masking plate 8 which can be moved against spring action to permit insertion of a coin by rotation of a knob 10. A plunger 43 which serves to lock the masking plate in slot-closing position is normally held out of locking position, so as to permit movement of the masking plate, by a lever 41, 42 under the action of a spring 44. When, however, a coin has been inserted and the mechanism is being set, the motion of the disc 27 is communicated to a shaft 39 carrying a pair of arms 40 which engage and move the lever 41, 42 into a position in which it releases the plunger 43, as in Fig. 13, so that the masking plate cannot be moved to permit the insertion of a fresh coin. The lever 41, 42 is retained in this position by a counterweighted catch 46, which is moved to release it as the coin falls out of its discharge opening in the guide groove, so that the masking plate can then the moved to insert a further coin.

Title: Apparatus for determining areas
IPC: G01B7/32
Filed: 1976-05-10
Abstract: 1508058 Determining areas FERRANTI Ltd 10 May 1976 [21 May 1975] 21976/75 Heading G4A An area on a map or chart enclosed by a line extending between at least three points, the part of the line between each pair of adjacent points being determined by a plurality of serially connected elements extending between those points, is determined from information representing the points and the elements. As described each element is a fixed-length straight-line segment extending in one of the four compass directions N, E, S, W, its direction being represented by a two-bit code. Information representing the points is stored in a store (S1), Fig. 1 (not shown) of a digital computer (C), Fig. 1 (not shown) which is connected via an interface I to a store S2 storing the two-bit codes representing the elements. Beginning at an arbitrary starting point, the line defining the area is followed in a given direction until the starting point is returned to. A logic unit CL2 generates in response to each two-bit code pulses a and b representing increments in the x and y directions and signals + and - representing the senses of those increments. A counter C2 counts the increments in the y direction as the line is followed, a register R3 storing the increments of area generated as the line is followed. The contents of counter C2 and of register R3 are constantly supplied to an adder/subtractor AS. Each a pulse causes the contents of adder/subtractor AS to be transferred to register R3, whereas each b pulse causes counter C2 to be incremented or decremented according as the + or - signal is present. The process terminates when the starting point is returned to, this being indicated by counter C2 storing zero (i.e. the final value of y is the same as the initial value of y), and by a "last element" signal from a logic unit CL1, register R3 storing the determined area. Counter C2 may alternatively count the increments in the x direction.

Title: Finely divided silica
IPC: C09C1/30
Filed: 1953-08-14
Abstract: Finely divided hydrated silica containing at least 90 per cent silica on a water-free basis and bound water in an amount corresponding to the formula H2O (SiO2)x where x is 3-85 and having a surface area of 50-200 sq. m./grm. and an average ultimate particle size below 0.1 micron is treated with 0.25-15 per cent of an unsaturated silanol or compound which can be hydrolysed to an unsaturated silanol.  The silica treated may be prepared as described in Specifications 745,822, 745,890, 756,857, 756,875, 756,877.  The silanol may contain an unsaturated alkenyl or alkinyl hydrocarbon or a halogenated hydrocarbon radical containing up to 8 carbon atoms, e.g. vinyl, allyl, crotyl proparyl, cyclohexenyl and butadienyl.  Silanols specified are triphenyl silanol and diphenyl silane diol. Hydrolyzable silanes specified are halosilanes, e.g. allyl trichlorosilane, diallyl dichlorosilane, vinyltrichlorosilane and the corresponding products in which the hydrocarbon radical is phenyl, vinyl phenyl, vinyl phenyl ethyl, methallyl, crotyl, 2-chloroallyl, propargyl and butadienyl; alkoxy silanes e.g. diallyl diethoxy silane, allyl triethoxy silane, phenyl triethoxy silane, alkyl triphenoxy silane and allyl triamyloxy silane; and amino silanes e.g. allyl tris (methyl amino) silane, diallyl diamino silane, triallyl amino silane and dicrotyl diamino silane. Best results are obtained with polymerizable halosilanes.  The silica may be treated by tumbling and passing the silanol or silane through entrained in a gas such as nitrogen.  Alternatively the silica may be treated with a solution of the silanol or silane in a solvent such as benzene or xylene.  Alternatively the silica may be mixed with a relatively large proportion of silanol or silane and then diluted with further silica.  The treated silica may be heated to 100-300 DEG C. or washed with water to remove the chloride content.ALSO:A finely divided hydrated silica (see Group III) is treated with 0.25-15 per cent of an unsaturated silanol or compound which p  can be hydrolyzed to an unsaturated silanol, and incorporated in rubber before or after treatment.  The treating agent is preferably a polymerizable unsaturated halosilane so that covulcanizing with the rubber can be effected.  Specifications 745,822, 745,890, 756,857, 756,875 and 756,877 [all in Group III] are referred to.
