Title: Improvements relating to the recovery of the ammonia contained in the gases from coke ovens
IPC: B01D51/10
Filed: 1919-11-14
Abstract: 153,177. White, A. E., (Soc. Franco-Belge de Fours Ó Coke). Nov. 14, 1919. Ammonium sulphate.-In the " semi-direct " method of recovering .ammonia as sulphate from coke-oven gases the hot vapours from the ammonia still are further heated by means of the waste gases from the coke-ovens, and then mixed with the cooled gases from the tar extractors, the mixture then passing to the saturator; the heat thus supplied prevents dilution of the acid in the saturator by the water present in the gases. Using the apparatus shown, the gases from the ovens 1 pass through coolers 3, a tar condenser 4, and a tar extractor 7 to the saturator 8; the ammoniacal liquor and tar from the coolers 3 and condenser 4 flow to a tank 5, whence the ammoniacal liquor passes to a tank 6, from which it is pumped to a still 10; the vapours from the still pass through a heater 11, in which they are heated to abont 200‹ C. by the waste heating gases from the ovens, and the heated vapours pass by pipe 12 to mix with the cooled gas on its way to the saturator.

Title: Photographic camera
IPC: G03B17/52
Filed: 1971-06-17
Abstract: 1356135 Self-processing cameras EASTMAN KODAK CO 17 June 1971 [17 June 1970] 28400/71 Heading G2A Film units 30 of the type having a rupturable pod of processing material so that they can be processed within the camera are transported from the cartridge 42 located in the supply chamber 4 to the exposure chamber 5, means being provided to prevent premature rupture of the pod at location 4. As shown, the film units 30 are loaded in a cartridge 42 which fits into the chamber 4 of the camera, and are transported one by one across to the exposure chamber 5. The units may be of the type having only one rupturable pod (38), or two (38', 39'). The transporting means is a carriage 62 which includes a pair of leaf spring arms 64 supporting a claw member 66 having claws 68 and shoe members 70 extending therefrom. Carriage 62 also has a further pair of leaf spring arms 72 which carry a roller 64. In Figs. 1 and 4 the carriage is shown in its extreme right hand position, in Fig. 1 preparatory to the insertion of a cartridge into the camera, and in Fig. 4 after an exposure has just been made. A platen 6 on a hinge 8, which has been open during the exposure step, is closed and latched. Carriage 62 is urged to the right by means of an external control member 85. During this movement roller 74 passes over pod 38', ruptures it, and spreads the processing material across the exposed film element to initiate the processing thereof. The film unit itself is retained against movement by biased retaining fingers 99 which engage in notches 41 in the film unit. As carriage 62 continues its movement, the axle portions 84 of roller 74 roll up ramp sections 88 on to a section 90, and then up further ramp sections 92 on to a section 94. The roller 74 is thus lifted clear of the pods 38, 39 on the next film unit, so that they are not ruptured prematurely. As the carriage completes its movement, the claws 68 engage behind the next unit 30 and the unit is spring-urged rearwardly, so that the roller 74 is now positioned between the pods Fig. 6 (not shown). The carriage is now pushed back to the right again, and now carries with it a new unexposed film unit into the exposure position, at the same time pushing the exposed unit out of the camera through an exit having a light seal 95. If the unit has two processing pods, the one which is still intact is ruptured at this stage by means provided for the purpose.

Title: Process and apparatus for binding spherical tanks
IPC: B21F17/00
Filed: 1951-12-07
Abstract: 710,664. Reinforcing spherical tanks. SOC. POUR LA FABRICATION DES BOUTEILLES METALLIQUES. Dec. 7, 1951 [Dec. 8, 1950], No. 28695/51. Class 69 (1) A spherical tank is reinforced by winding it with steel wires in diametral planes inclined at one or more constant angles to a diameter of reference of the tank. As shown in Fig. 1, the tank 1 is mounted at two diametrically opposite points a, b on a pair of arcuate arms 2, 3 which revolve about a common axis x, y. Wire from a drum 8 is attached to the sphere and, when the arms 2, 3 are rotated about axis x, y, a zone on either side of the great circle c, d is bound. the sphere is then rotated slightly about the axis a, b, resecured and another zone bound by rotating the arms 2, 3 about the axis x, y. When sufficient zones, the median planes of which are all tangential to the cone of semi-angle x, have been wound the mounting points a, b are moved to another position on the arms 2, 3, Fig. 2, and another series of zones wound. Further movement of the points a, b provides further series of zones. The zones may be wound over a castellated strip, the projections of which are turned up to secure the outside wires. The members for securing the tank on the arcuate arms 2, 3 each comprise, Fig. 6, a bush 12, which may be fixed by screws 14 at various positions on the parallel strips 10, 11 forming each of the arcuate arms, a square-sectioned part 17 attached to the tank and a sleeve 16 which fits over the part 17 and into the bush 12. In addition, the sleeve 16 has two spurs 20 which are retained against teeth 21 on the bush 12 by a nut 23 on the threaded portion 22 of the part 17. Thus the sphere may be rotated by loosening the nut 23 and raising the sleeve 16.

Title: Improvements in or relating to filling apparatus
Inventor: BURDIN NELSON VINCENT
IPC: B65B39/00
Filed: 1951-12-07
Abstract: 711,384. Filling viscous liquids. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 3, 1952 [Dec. 7, 1951], No. 28711/51. Class 125 (2) In apparatus for filling containers with viscous liquids such as paint comprising a paint reservoir 1, a sealing gasket 17 for the container 18 and tubes 3, 4 for paint and displaced air having valves 5, 6 respectively, the valve 6 is opened before the valve 5 to allow paint in the displaced air tube to drain into the container to be filled, after filling the valve 6 is closed before the container is lowered to retain excess paint in the tube 4, and the effective cross-sectioned area of the tube 4 is great enough to allow air to pass up through paint contained therein. In operation, the container 18 is raised by its support to engage the gasket 17 which pushes up a rod 8 to raise a cross beam 7 which lifts the valve 6 to allow paint to drain into the container. Further raising of the container causes the upper surface of gasket 17 to seal against a sleeve 12 and when the cross-beam 7 reaches the top of a slot 19 in the operating rod of valve 5, the latter is opened. When the paint level reaches the outlet of tube 4, paint rises in this tube and then filling stops. The rod 8 is knocked from the gasket 17 and the valves 5, 6 close. The container is then lowered on its support. The valves 5, 6 may be moved downwardly to open position and the invention may be embodied in a rotating table machine. U.S.A. Specifications 1,940,806 and 2,016,378 are referred to.

Title: Improvements in or relating to electric circuit arrangements providing earth leakage protection
IPC: H02H3/06
Filed: 1965-07-08
Abstract: 1,105,027. Protective arrangements. G. A. D. GORDON. 4 July, 1966 [8 July, 1965], No. 28923/65. Heading H2K. An earth-leakage protective arrangement for a load 3, e.g. a neon sign or a hand-operated electric tool, connected to the secondary winding of a transformer 2, comprises a reactive impedance 7, 8 connected between the secondary winding and earth, means 13 for rectifying any voltage across the impedance, a relay 10 having contacts 9 in the primary circuit of the transformer and amplifying means for controlling the relay in dependence on the leakage current through the impedance. In the arrangement shown a thermionic valve 11 is normally conducting, the relay 10 is energized and holds its contacts 9, 18 closed. When earth leakage occurs, the voltage drop across a resistor 7 and capacitor 8 biases the valve 11 so that the current through the valve and relay 10 is reduced. The relay 10 opens its contacts 9 to interrupt the main supply and opens its contacts 18 to prevent an automatic reclosing operation when the leakage current ceases due to the opening of the contacts 9. Reclosing may be effected by operating a push-button switch 19. In a modified arrangement, Fig. 1 (not shown), the contacts 18 and switch 19 are omitted, a time delay circuit being provided so that the opening and reclosing cycle repeats slowly. Other modifications include the use of a bi-stable relay having an opening winding and a closing winding, Fig. 3 (not shown), the use of two relays, Figs. 4 and 5 (not shown), and the use of a transistor instead of a thermionic valve Figs. 6 and 7 (not shown). The impedance connected between the secondary winding and earth may be a transformer and warning devices may be provided.

Title: Improvements relating to the manufacture and use of resinous anion-exchanger products
IPC: C08G12/04
Filed: 1946-09-27
Abstract: Insoluble basic resins for use as anion-exchangers are obtained by dissolving an initial condensate, obtained by heating urea or cyanoguanidine with formaldehyde, in aqueous formaldehyde while cooling and adding to the solution a cold acid solution of m-phenylenediamine or other aromatic amine to form a gel which is dried to form a hard resinous product.  In a modification two separate condensates of urea-formaldehyde and cyanoguanidine-formaldehyde are employed and mixed with the aromatic amine.  The initial condensation is arrested before reaching a viscosity at which it would form a gel insoluble in formaldehyde.  In examples: (1) 55 parts cyanoguanidine, 100 parts 30 per cent formaldehyde and 10 parts HCl (d = 1.19) are heated for 10 minutes under reflux.  The product is cooled to 2-5 DEG  C. and then mixed with an ice-cold solution of 100 parts m-phenylene diamine in 60 parts HCl and 150 parts water.  After reaction during which the temperature rises to 35 DEG  C. the product sets to a hard gel which is broken into lumps and dried at 80-100 DEG  C.; (2) the cyanoguanidine is replaced by urea; (3) separate condensates of cyanoguanidine and urea with formaldehyde are prepared, mixed together and the aromatic amine is added to the mixture.
