Filed: 1920-09-20
Abstract: 172,337. Douglas, R. P. Sept. 20, 1920. Strainers having sheet straining-materials. - Apparatus for washing, drying and neutralizing ammonium sulphate crystals consists essentially of a receiver-bucket having a perforated bottom and a suction vessel which together with a tube depending from the mouth of the vessel forms a trap for the liquor contained therein. Two forms of the apparatus are shown in the diagrams. Having been sucked substantially dry by connecting vent e<1> with a suction device, the crystals in the receiver a are washed with a small amount of water and if a neutral salt be desired, they are then washed with ammonia. Alternatively, the crystals may be treated with steam or gaseous ammonia in which case the receiver is fitted with a lid having an inlet pipe and valve. The filtered liquor after leaving the bucket forms a trap with the tube e and then passes through the outlet h to the mother-liquor tank or saturator. For convenience in transporting, the bucket is provided with trunnions a<2> or fittings enabling it to be carried by an overhead system. The bucket is made of wood or cast-iron, or like the suctionvessel b, it may be lined or made entirely of lead, copper, or other acid-resisting material.

Filed: 1974-07-18
Abstract: 1454806 Detecting neutrons SIEMENS AG 18 July 1974 [1 Aug 1973] 31975/74 Heading G6P A self-powered neutron detector comprises a neutron-activable emitter 1 separated by an insulating layer 5 from a metal collector 4, there being a neutron unresponsive metallic layer 2 interposed between the insulating layer 5 and emitter 1 and in electrical contact with the latter. The metal layer 2 acts to reduce any signal from delayed #-radiation from the emitter 1 and affords some γ-compensation, depending upon the material used. Thus, where the emitter material has an atomic number less than, or equal to, that of the collector material (e.g. emitter comprises cobalt), γ-current is reduced by using zirconium for the layer 2; or, where the emitter material has an atomic number greater than that of the collector material (e.g. emitter comprises rhenium or thulium), γ-current is reduced by using a Ni-Cr-Fe alloy for the layer 2. The layer 2 may be constituted by a metal tube in which case the emitter might comprise a pulverous material.

Filed: 1975-08-01
Abstract: 1512809 Lock NEIMAN SA 1 Aug 1975 [29 Aug 1974] 32229/75 Heading E2A An antitheft device particularly for a steering column lock comprises an axially slidable cylinder lock 4 to which is attached an actuating drum 15 with a cam surface 19. Bolt 16 is urged to the locking position by spring 16a acting on rod 22; a portion 17 of the bolt 16 carries a spring loaded plunger 20, which in the locking position (Fig. 1) engages the underside of drum 15. Insertion of key 36 forces rollers 23, 24 to move radially and axially along fixed surfaces 26, 27 and so forces lock 4 to move axially against the action of spring 35 held between fixed thrust-ring 28 and lip 34 at the end of the lock. This depresses drum 15 so that cam surface 19 engages the end portion 17 of bolt 16. The key 36 also unlocks the lock 4 and permits it to rotate, such rotation withdraws bolt 16 by the action of cam surface 19 on portion 17. At full withdrawal (Fig. 8) the cam 19 has moved 17 so far that plunger 20 is free of the under surface 18a of drum 15 and springs out so that its side may engage peripheral surface 37 of drum 15 and so hold bolt 16 in the withdrawn position when lock 4 is rotated back to its starting position. Removal of key 36 permits the rollers 23, 24 to move together and therefor spring 35 to return lock 4 to the position shown in Fig. 1. In this position the plunger 20 no longer engages side 37 of drum 15 so the bolt 16 returns under the influence of spring 16a to its locking position. Rollers 23, 24 are housed in a T-shaped groove (Fig. 4) in the front surface of the cylinder lock 4. Thrust ring 28, which rotates with the cylinder but is axially fixed, has strips 26, 27 projecting into the groove to provide surfaces for the rollers to bear on.

Title: Improvements in the purification of solutions of zinc salts
IPC: C01G9/04
Filed: 1926-12-23
Abstract: 263,809. Vohl & Co., Akt.-Ges., A. Dec. 24, 1925, [Convention date]. Zinc and other salts. - Purified zinc salts areobtained from waste liquors containing cellulose slimes and dissolved iron compounds by a process in which only zinc ions are introduced in the several treatments. Iron is substantially removed before filtration by oxidation and precipitation, for instance with halogens and basic compounds such as barium carbonate. Organic matter is destroyed before or during evaporation by oxidizing media such as nitric acid or permanganates, after which traces of coloured iron' compounds are reduced by acid and zinc. In an' example in which the zinc is present as chloride, the solution is treated with hydrogen peroxide to oxidize the iron, and then with zinc carbonate, and is filtered, the filtration being treated with zinc chlorate during evaporation to destroy organic matter. Finally, zinc dust and hydrochloric acid are used to reduce residual coloured ferric salts. The Specification as open to inspection under Sect. 91 (3) (a) comprises a general aspect where the salt solution may be that of anv metal. The metal ion of reagents added is either the metal of the salt to be obtained in a purified state, or one which can be easily removed, such as barium. Alternative examples are given of the treatment of zinc chloride solutions. In one such example, the oxidation of the iron is effected with barium peroxide, the iron is precipitated by barium carbonate, and the barium is removed by zinc sulphate. During evaporation of the filtered solution, barium chlorate is added to oxidize the organic matter, and the barium is removed by zinc sulphate. In other examples, the oxidation' of the iron is effected by bromine or zinc peroxide, the iron being precipitated by baryta water; the oxidation of the organic matter is effected with chloric acid. The Specification as accepted is limited to the recovery of zinc salt solutions from waste liquors.

[Class 98 (i)] In a process of composing music photographically, component elements of the musical signs carried by a matrix are selectively imprinted on a sensitized sheet to form complete musical signs. The matrix may also carry signs, such as key signatures, complete in themselves. The sensitized sheet is afterwards developed and used in lithographic or typographic printing. In the apparatus shown, the sheet is mounted on a carriage 10<a> moving on rails 27<cd> on a lower carriage 10 moving on rails 8, 9, on a base 6. The lower carriage is movable by a knob 15 through gearing provided with a stop-wheel 20 and latch 21 which ensures that the carriage moves through steps of equal magnitude. The upper carriage 10<a> is moved by a knob 22 through gearing provided with coarse and fine adjustments, and carries also a pillar 10c supporting the original manuscript, a pointer 74 on the machine indicating on this the position corresponding to the printing position on the sensitized sheet. The signs are provided on a disc 33 directly over the sensitive surface, and carried by a plug 96 mounted in a socket 40 and provided with a spring tending to turn it through 90‹. Rotation is prevented by a stop arm 57. The signs are selected by the depression of keys 80 followed by depression of the key 46 which withdraws the stop arm 57 from the stop 97 so that the plug 96 rotates until an arm 401 carried thereby abuts against the depressed key. The disc 33 is divided into four sectors, any of which may be used by turning the plug 96 in the socket 40. The printing of the sign is effected by the light source 103, which is lowered on the disc 33 by the depression of the key 46 which at the same time closes the contact 76 lighting the source 103. The casing containing the light source is provided with adjustable shutters for use with signs of different sizes.

Abstract: 605,065. Temperature alarms. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and ALCOCK, J. F. Dec. 3, 1945, No. 32689. [Class 47 (i)] [Also in Group XXXV] In a temperature control device the electric circuit controlling the heat source includes a resistor of fusible material, subjected to the temperature under control, and which undergoes a large fall of resistance as the temperature rises in the neighbourhood of fusion. In the embodiment shown, the alternator 4 energizes the solenoid 5, connected in series with the fusible salt or mixture of salts 3, supported in the casing 1 which extends through the wall 14 of the exhaust duct of a gas turbine. Upon the temperature of the duct gases rising to a point near the fusion temperature of the salt, the resistance of the later is reduced considerably, the current through solenoid 5 rises and the plunger 7 is drawn inwards against the thrust of spring 8 sufficiently for the valve 9 to interconnect the ports 10, 11 so as to byepass the fuel supply to the burners and reduce the duct temperature. Alternatively, the valve 9 may open a passage to a spill pipe and thereby decrease the supply of burner fuel. In a further embodiment (not shown) the fusible salt elements round the circumference of the duct may be connected either in series or in parallel to give effects related to minimum local temperature or a maximum local temperature respectively. Mean temperature effects are obtained by the insertion of resistors in series with the elements when parallel connected and thermionic amplifiers may be associated with the elements. A non-eutectic salt mixture may be employed in which the solidus acts as the spacing insulator and the liquidus as the conductor. The invention may also be applied to a gas-turbine engine employing a heat exchanger between the compressor and the turbine.
