Title: Improvements relating to the production of zinc
IPC: C22B19/18
Filed: 1943-03-13
Abstract: 572,961. Extracting zinc. NATIONAL SMELTING CO., Ltd., ROBSON, S., and DERHAM, L. J. March 13, 1943, Nos. 4131/43 and 3176/44. [Class 82 (i)] In a method of condensing zinc from a gaseous mixture containing both zinc vapour and carbon dioxide or other gas capable of reacting with zinc vapour, the gases are shock-chilled by being brought into intimate contact with molten lead or molten leadrich alloy, the temperature of which is not greater than 550‹ C. The molten lead or alloy is circulated through a cooler, in which the zinc separates and is removed, and the lead or lead alloy is re-employed for condensing further quantities of zinc. The process may be employed for treating gases obtained by smelting zinc ores in a blast furnace, e.g. as described in Specification 572,960, in which the gases liberated in the shaft 1, Fig. 1, of the furnace pass out through a heated coke column 10 and up through a packed tower 20 down which is 'showered molten lead or lead alloy which has been elevated from a cooler 30 into which it runs from the base of the tower. Alternatively, the gases may pass through a spray or curtain of molten lead or alloy thrown up by a paddle-wheel 57; or they may pass a baffle 41 depending into the molten lead or alloy 42 contained in a chamber 40.

Patent GB-797114-A (GB)
Title: Improvements in or relating to automatic gain control systems for television receivers
IPC: H04N5/52
Filed: 1956-02-13
Abstract: 797,114. Automatic gain control. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 13, 1956 [Feb. 21, 1955], No. 4412/56. Class 40 (5). In a television A.G.C. circuit for positivelymodulated signals, the complete video signal is derived, in such sense that the synch. pulses are positive-going, from the anode of an amplifier 1 and is applied via a blocking condenser to the anode of a diode 3. The complete signal is also fed to a synch. separator valve 2a in whose anode circuit negative-going synch. pulses appear; these are inverted and amplified by valve 2b and fed as positive-going pulses to the cathode of the diode 3. The diode 3 is as a consequence, rendered non-conductive during the synch. pulse periods and so acts as a black level clamp, the black level in the waveform applied to its anode being held approximately at the negative potential which is applied to terminals 4. This potential may be made variable and used as contrast control, and is such that valve 6 is only rendered conductive by the synch. pulses in the signal at the anode of diode 3. Pulses proportional to the height of the synch. pulses appear in the anode circuit of the valve 6 and are rectified by an A.C.-coupled diode 7, the resulting negative voltage across the load resistor 8 constituting the A.G.C. voltage. Reference has been directed by the Comptroller to Specification 774,578.

Filed: 1918-03-13
Abstract: 122,736. McKay, T. G. March 13, 1918. Shafts and shafting.-For repairing broken crank and other shafts, the two ends to be joined are connected by an interlocking connexion, or they are joined to a filling-piece by interlocking connexions of a similar nature. The connexion is then completed by welding, preferably by an electric are, metal being filled in drop by drop into the angles or spaces between the interlocking connexion. As applied to a joint in which two parts of a shaft 1 are connected by a filling-piece 7, each end of the shaft is formed with a pair cf splines or dowels 3 projecting from a web 2, the parts being shaped as shown and being formed with chamfered edges 5, 6. The piece 7 is formed with a web part 8 provided with splines or dowels 9, the two sets of which are in planes at rightangles to one another. When the filling piece 7 is dispensed with, the ends of the shaft 1 are formed as shown in Fig. 2, and interlock directly.
Patent GB-139003-A (GB)
Title: Improvements in or relating to electrical signalling systems, such as are used in mines
IPC: B66B19/06
Filed: 1919-02-22
Abstract: 139,003. Automatic Telephone Manufacturing Co., and Green, H. Feb. 22, 1919. Mine signalling systems; recording orders.-Relates to a mine signalling system as described in Specification 139,004, in which the signals are cancelled on fulfilment of the order. Means are now provided for recording each signal by a duplicate which persists either until a new signal is received, or, when the apparatus has been suitably manipulated, until the record is cancelled by hand. In the above-mentioned Specification, the signal currents energize one of eight relays 1 - - 8 to illuminate one of nine visual signals, the signal " stop " or " raise " being given by relay 1, according as the engine is running or not. In the present invention, a duplicate signal for recording purposes is illuminated by the action of one of the relays 17 - - 25, which are self-holding through their windings 26 - - 34. The relay 17 or 18 (for " stop " or " raise ") is energized by the relay 1, according as the engine is running or not since the circuits of these two relays pass respectively through the contacts 44, 47 of the magnet 39, which is energized so long as the engine is running. The holding-circuits through the windings 26, 27, 28 and 30 - - 34 pass also through the back contact of the relay 52, which is energized at every fresh signal so as normally to cancel the record. When desired, however, the banksman, by pressing the key 70, can energize the relav 38, when the record will be retained until cancelled by the releasing key 71. For the relay 38 is self-holding through its armature 73, and it completes through its armature 37 the sell-holding circuits of any one of the relays 17 - - 25 which may be in action. Simultaneously, the relay 38 prevents any new signal from being recorded by breaking at 45, 41, 36 respectively the circuits which initially energize the relays 26, 27 and 28 - - 34. The record of the " men " signal can only be cancelled, in any case, bv manually operating the key 69. The relay 38, which prevents the normal cancellation of the record, is always energized when the " stop " signal is given, by means of its winding 75. Specifications 18780/14 and 118,828 are also referred to. The Provisional Specification states that the apparatus may be arranged for any number of levels by increasing the number of relays.

Title: A telecommunication system with relay selectors
IPC: H04Q3/00
Filed: 1953-02-18
Abstract: 759,597. Automatic exchange systems. LICENTIA PATENT-VERWALTUNGS-GES. Feb. 18, 1953 [Feb. 28, 1952], No. 4529/53. Class 40 (4). In an automatic satellite (non-exchange) using relay selectors in which the line-connecting relays of each selector have slightly overlapping operated periods, in order to prevent momentary parallel connection of a junction to two subscriber's lines which results in clicking noises if one of the lines is engaged, the odd and evennumbered lines are grouped and the groups are alternately connected to the junction by means of two relays each operated by the release of the other and each dependent for operation on whether the selector is set to an odd or evennumbered subscriber. In a system similar to that shown in Fig. 3 of Specification 759,589, the two relays are the control relays S1 S2 (not shown) of the relay selector. Thus oddnumbered lines Tnl are connected over contacts such as 1<II1>, 1<II2> of the corresponding lineconnecting relay and contacts S2<I>, S2<III> of the control relay S2 to the junction VL1 and similarly even-numbered lines Tn2 are connected over contacts 2<II1>, 2<II2> of the corresponding lineconnecting relay and contacts S1<I>, S1<III> of the control relay S1. The relay selector is similar to that described in Specification 732,354.
Patent GB-792337-A (GB)
Title: Cellulose ester textiles and compositions
IPC: C08L1/10
Filed: 1956-02-14
Abstract: The tendency of dyeings or prints on textile materials of cellulose lower aliphatic esters, containing at most 0.29 hydroxyl groups per anhydroglucose unit, to change in shade on exposure to acid fumes is reduced by treating the textile before, during or after dyeing, with up to 6 per cent by weight of a polymer of an ethylenically unsaturated compound containing a pyridine group. Specified polymers, including copolymers with one another or with other ethylenically unsaturated monomers such as styrene or methyl methacrylate, are 2-vinyl-, 4-vinyl-, 2-methyl-5-vinyl-, 2-vinyl-5-methyl-2-vinyl-5-ethyl-and 2-ethyl-5-vinyl-pyridine. The polymer may be added to the spinning solution from which the fibres are spun or it may be dispersed in the dyebath, or the fibres may be treated with a solution or aqueous dispersion of the polymer.  Dyeing is effected with disperse acetate dyestuffs, preferably in the presence of an assistant, which may be applied before or during dyeing, such as pine oil, tripropyl or tributyl phosphate, diethyl phthalate or N:N-di-(hydroxyethyl)-capramide, as described in Specification 791,392.  After dyeing, the textile containing the polymer is preferably heat-treated at 190 DEG  C. or above, by means of hot air, steam, molten metal, heated rolls, infra-red radiation or dielectric heating, whereby the "gas-fading" tendency is further reduced.  When coloration is local, the tendency of the uncoloured portions of the textile to become discoloured after heating is obviated by treatment, before or after heating, with a bleach such as sodium or calcium hypochlorite, sodium chlorite or peracetic acid.ALSO:A polymer of an ethylenically unsaturated compound containing a pyridine group is incorporated in a spinning solution of a cellulose lower aliphatic ester, containing at most 0.29 hydroxyl groups per anhydroglucose unit, whereby the filaments spun from such solution are given, upon subsequent dyeing, a reduced tendency towards "acid-fading."  Specified polymers, including copolymers with one another or with other ethylenically unsaturated monomers such as styrene or methyl methacrylate, are 2-vinyl-, 4-vinyl-, 2-methyl-5-vinyl, 2 - vinyl - 5 - methyl -, 2 - vinyl - 5 - ethyl - and 2 - ethyl - 5 - vinyl - pyridine. Specified highly esterified cellulose esters, which may be spun in solution in methylene chloride-lower alkanol solvent, are the acetate, propionate, butyrate, acetate-propionate, acetate-butyrate and acetate-formate. Specification 791,392, Group IV(c)], is referred to.

Abstract: 697,317. Ironing-presses. BROWN & GREEN, Ltd., and GUDGEON, R. P. Sept. 12, 1950. [Feb. 23, 1950] No. 4731/50. Class 138 (ii). In a garment press having a plurality of press tables mounted for rotation about a common support to bring them successively into position beneath a fixed press head, at least one of the press tables is divided into three or more spaced bucks 5, 6, 7 adapted to receive portions of a plurality of garments and to be simultaneously moved into engagement with a single pressing surface on the press head. In the example shown the bucks 5, 6, 7 are pivotally mounted on arms 3, 4 pivotally mounted on a support 2 secured to a base 1. The outer bucks 5, 7 are provided with inwardly directed bulges 10, 11, and recesses 12, 13 on their outer edges. The bulges 10, 11 enable the collar of a shirt to be fully supported on a buck, as shown in Fig. 6, while the recesses 12, 13 permit the collar to be turned down below the pressing surface during the pressing of a full yoke, as shown in Fig. 4. Pairs of spring loaded arms 14, 15 rotatably mounted in the arms 3, 4 press the shirt against the buck and thus hold the collar firmly in position. Figs. 4 to 9 illustrate the pressing of shirts employing a press table according to the invention in combination with a conventional press table. While the yokes and cuffs of two shirts A, B are being pressed (Fig. 4) the front of a third shirt C and the back of a fourth shirt D are being arranged for pressing on a conventional bosom-body buck 20 (Fig. 5) having the usual collar block 21 at one end. Shirts A, B are then relaid as shown in Fig. 6 to press the collar of one and the sleeves of the other. In Fig. 7 (not shown) shirts C, D are reversed while in Fig. 8 (not shown) the arrangement of shirts A, B in Fig. 6 is reversed. Finally, Fig. 9 (not shown), shirts C, D have their folded or doubled sides pressed. In this method two shirts are completely finished at every sixth loading. In a modification Fig. 3 (not shown) the centre buck is formed with a pair of centrally directed recesses to enable half sleeve portions to be laid on the buck. Thus in Fig. 10 (not shown) the collars of two shirts are laid on the outer bucks while the bottom half sleeves are placed on the centre buck, with the cuffs hanging in the recesses. In Fig. 11 (not shown) the top half sleeves are laid on the centre buck while the bottom half sleeves hang through the recesses. Specifications 684,681 and 684,682 are referred to.
