Title: Method for the desulphurisation of gases by means of a granular or moulded desulphurisation material
IPC: C10K1/20
Filed: 1951-11-05
Abstract: <PICT:0697204/III/1> In desulphurizing gases with moulded or granular purifying material by passing the material downwardly in counterflow to the gas in a layer over an inclined surface, the gas velocity is sufficiently high largely to counteract the pressure of the material on the surface without impeding its descent.  Several purifier sections may be used in series side by side or one over the other.  A high gas velocity is also employed for regeneration.  With an average granule size of 5-10 mm. the gas velocity should be 20-80 cm. per sec.  In the purifier shown alternate cones 2 and funnels 3 composed of rings 4 are disposed throughout the height of the tower which has a pocket feeder 9 at the top and a bottom discharge 11.

Abstract: 815,440. Linkwork. NATIONAL CASH REGISTER CO. July 9, 1957 [Aug. 29, 1956], No. 26380/56. Class-80 (3). [Also in Groups XVI and XIX] A cash register (see Group XIX) which prints on an inserted slip 45 incorporates an adjustable linkage by which the slip may be fed to a variable extent and in one direction or the other. The feed is effected by a rubber block 33 carried by a frame 27 slidable on two sets of parallel links 13 rockable by a pair of similar cams 20 to raise the block to effective position and lower it. The block is moved laterally by a link 34, one end of which is adjustable in a diametral groove 35 in one of the cams 20. In operation, the block 33 is first moved to one end position. It is then raised and moved to its other end position, after which it is lowered and finally restored to its central position. By adjusting the pivot of the link 34 in the groove 35, the amplitude of the longitudinal movement of the block 33 may be varied, and the direction of its movement when in the raised position may be determined. The groove 35 is T-shaped in section and receives the head of a screw on which is freely mounted a hub 38 for the end of the link 34. A knurled nut 40 enables the hub to be clamped in any desired position along the groove.

In the construction shown in Figs. 1 and 2 the fuel is supplied from a passage 3 to a duct 7 provided between the shaped inner edges of two plate-like members 8, 9, which are located between two semicylindrical members 6, the assembly being housed in an outer casing 1. The outer edge of the plate 9 is relieved slightly as shown in Fig. 1 to permit the outward movement of the member under the fuel pressure against the action of an adjustably spring-loaded plunger 12 the contacting portions 10 of the plates then separating to pass the fuel. Simultaneously with the fuel delivery air is admitted under pressure at 4, Fig. 2 and reaches an annular, groove 19 surrounding the nozzle outlet where it raises a spring-loaded valve 15 and mixes with and atomizes the fuel at the nozzle outlet. At the end of the injection period the fuel and air pressures are reduced allowing the outlet valves to close. Water is then admitted at 5 and flows from an annular groove 17 over the upper face of the valve 15 to the nozzle outlet ; on the re-establishment of the air pressure the water injection is automatically checked by the valve 15.
