Title: Improved method and apparatus for operating a countercurrent vapor-liquid processing zone
IPC: B01D3/18
Filed: 1951-10-09
Abstract: 690,795. Treating liquids with gases. STANDARD OIL DEVELOPMENT CO. Oct. 9, 1951 [May 16, 1951], No. 23516/51. Class 55(ii) In bubble towers in which the contacting liquid flows across the plates and downwardly from plate to plate through downcomers, the capacity of the tower is increased by introducing into the liquid which has descended through a downcomer but which has not reached the first row of bubble caps, jets of gas or vapour from the stage below. In the form shown, a bubble tower 1 has plates 2 and 3 provided with bubble caps 5 and 7. Liquid descending through a downcomer 8 passes across plate 3, over a weir 9 into a downcomer 10 and across plate 4 to pass over a weir 11 to the stage below. A row of holes 13, 14 is provided across plates 2 and 3 so that vapour or gas from a lower stage may pass into the liquid on the plate above in the form of jets. Excessive entrainment of the liquid in the jets is prevented by baffles 15 and 16 upon which the jets impinge. The effect of the jets is to aid the passage of liquid across the tray and to reduce the downcomer liquid level, so minimizing tray flooding and allowing a higher throughput to be obtained.

Title: Improved control apparatus for the feed rollers of web feeding machines
IPC: D06B17/02
Filed: 1953-08-31
Abstract: 742,431. Feeding webs. SAMCOE HOLDING CORPORATION. Aug. 31, 1953 [Oct. 4, 1952], No. 24056/53. Class 100 (1).  A web feeding device comprises, in the form of Fig. 1, a pair of feed rollers 11, 12 for advancing the web 16 and a speed-control mechanism for the second roller comprising a container 17 mounted on levers 23 between the rollers and adapted to receive the web from the first roller and to discharge it to the second roller on demand, the weight of web accumulated in the container determining the speed of the second roller. The second roller is driven by a pulley 14 adapted to be rotated by contact with a continuously moving belt 15. The belt is urged into contact with the pulley by a roller 26 mounted on an arm 25 fixed to the shaft 24 carrying the levers 23. The axle 29 of the roller 26 carries an arm 28 having a threaded spindle supporting an adjustable counterweight 27. The counterweight is adjusted so that when the container is empty the roller exerts no pressure against the belt and the feed roller 12 is not driven but when a predetermined length of web is supported by the container the feed roller is driven at full speed. By this means the length of web in the container is maintained substantially constant. The container 17 comprises a rear member of wire mesh having a curved lower portion 20 and a front member 18 also of wire mesh so that the section of the container is approximately of J-shape. In the modification shown in Fig. 2 guide sleeves 31 fitted to the ends of the container are slidable on vertical rods 32. Chains 33 connected to each end pass over pulleys 34, 35 and carry counterweights 38. To the shaft 37 of pulley 35 is connected an arm 47 having a curved slot 46 receiving a pin 45 mounted on a lever 43. Lever 43 supports at its other end a variablespeed coupling 42 having one pulley driven from the main drive belt 15 through pulley 38, belt wheel 40 and belt 41. The other pulley of the coupling is connected by belt 30 to the second feed roller. Counterweights 50, 51 are mounted adjustably on arms 48, 49. Movement of the container 17 due to change in the amount of web supported therein causes angular displacement of pulley 35 and, through the pin and slot connection 45, 46, movement of variable-speed coupling 42 and a corresponding change in the speed of the second feed roller so that the amount of web supported in the container is maintained substantially constant as determined by the setting of the counterweights. Specifications 742,429 and 742,430 are referred to.

Abstract: 1,162,821. Purification of water by freezing. SIMON-CARVES Ltd. 22 Aug., 1966 [8 June, 1965], No. 24145/65. Heading B1G. [Also in Division C1] In a process for the desalination of brine in which butane in a compression-condensation circuit is passed in direct contact with the brine in a freezing vessel to effect partial freezing, the slurry in the freezing, the slurry in the freezing vessel is agitated in such a manner as to maintain a substantially uniform distribution of ice crystals in the slurry. As illustrated, butane is compressed at 48 and passed through a heat exchanger 10 in direct contact with cold mother liquor to a condenser 6, whence it passes to the freezing vessel 2 in which it evaporates in direct contact with feedstock brine prior to return through a heat exchanger 8 to the compressor 48. Feedstock brine passes through the heat exchanger 8 in direct contact with brine, and through a double direct contact heat exchanger 11 in which it is cooled by cold mother liquor, to the freezing vessel 2 in which it is partially frozen by the boiling butane. Brine/ice slurry is passed to a centrifuge 4 from which separated brine mother liquor is passed by a pump 58 through the heat exchangers 11 and 10 to an exit line 29 including a butane separator 55. Purified water is added to the ice crystals at the centrifuge and in a tank 36 and the resulting slurry is passed by a pump 42 to the condenser 6 in which ice is melted by direct contact with partially gaseous butane. Purified water from the condenser is passed in part to the centrifuge and tank 36 and the remainder passes through a butane separator 46 for use. The freezing vessel 2 is provided with paddles 20 and with fixed baffles, and baffles may be provided over the butane outlet and brine/ice outlet to prevent the passage of brine and butane respectively. In a modification (Fig. 1, not shown), the heat-exchanger 11, pump 58 and butane separator 55 are omitted and all heat exchangers other than the freezing vessel itself are of direct contact type. Preferred operating conditions are disclosed.

The firing pin has an enlarged portion 16 and is secured at its rear end to a member 26 which slides in a tubular guide 27 and is acted upon by a return spring. A device 18a is slidably mounted on the firing pin between the parts 16 and 26, and is formed with an inclined surface 23 adapted to engage the fins 12. Operation. The return spring acting on the member 26 urges the firing pin, and with it the device 18a and the lock, forwardly from the retracted position shown in Fig. 1, thus introducing a round b into the cartridge chamber 6. At tnis stage the lock closes the recess 8 at the rear end of the barrel and further forward movement of the lock is prevent ed The firing pin, however, continues its forward movement, and in doing so causes the surface 23 to open the fins 12 into locking engagement with a fixed ring 28. Upon firing, the combustion gases pass rearwardly through bores e, Fig. 4, of the cartridge shell and eject the percussion cap d which in turn projects the firing pin to the rear. In this latter movement the part 16 of the firing pin drives the device 18a to the rear, thus allowing the fins 12 to become unlocked, the return spring is compressed, and the cap d after striking a wall 30 in the lock is ejected through the opening 5.
