Title: Compression sprayer
IPC: F16J15/02
Filed: 1961-08-25
Abstract: 963,912. Forcing liquids by gaseous pressure. ROOT-LOWELL MANUFACTURING CO. Aug. 25, 1961 [Oct. 27, 1960; Feb. 17, 1961], No. 30794/61. Heading F1R. [Also in Divisions F2 and E2] A compression sprayer comprises a spray solution tank with an air pressure pump therein, a grommet for sealing the discharge tube projecting through an opening in the tank or a seal at the fill opening in the tank head, the seal or grommet being subjected to the air pressure in the tank. A dish-shaped head 17, Figs. 2 and 3, of a tank 10 has a fill opening 18 around which an annular locking clip 22 is secured at its flange 21 by bending over a flange 19 of the head 17. A member 26, pressfitted into a pump cylinder 29, has slots 30 with radial notches 31 into which fingers 36, with radial lips 37, may be guided against the action of a spring 51. Then, on clockwise rotation of the plunger shaft 33, the lips abut the underside of the member 26 and each finger 36 abuts one end of one slot 30, so that on further clockwise rotation the member 26 also rotates and thereby engages its upper and inclined surfaces 48 (see Fig. 10) with the undersides of the circumferentially spaced lips 24 on the locking clip 22. The member 26 is thereby screwed into the clip 22 until it abuts stops (not shown) at the ends of the lips 24 and projections 49 of the member 26 are forced against a seal 38 to effect sealing. Fig. 2 shows the pump assembly in the released position preparatory to removal. Increases in air pressure within the tank 10 further increase the sealing by the action of the pressure on the lips 44 and 45 of the seal 38. A grommet 53 is provided around a discharge tube 12 which is preferably flexible and leads to a metal or rigid tube 14 having an adjustable spray nozzle 15 and a manually operated control valve (not shown). The grommet 53 is shown resting on projections 57 in which position there is a passage between the interior of the tank 10 and the atmosphere. However, when a positive pressure exists in the tank, the grommet is forced upwardly to engage its tapered portion with the hole 54 and thereby seals off this passage. In addition, the pressure within the tank improves the sealing between the grommet and the pipe 12. The pressure in the tank 10 may be released by pushing the grommet 53 downwards on to its projections 57, thereby opening the passage to the atmosphere. Additionally, any liquid remaining in the tank 10 may be drained through this passage. An alternative form of grommet, Fig. 12, has serrations which engage substantially similar serrations 71 on the plastic discharge pipe 12a. Sealing is effected by engagement of a tapered portion 59 located below an annular recess 73 and by the action of the air pressure on a lip 75.

Abstract: 1424601 Rolling mills NIPPON STEEL CORP 29 June 1973 [30 June 1972 (2) 3 July 1972 13 July 1972 (4) 1 Aug 1972 (2) 19 Aug 1972 22 Dec 1972 (2) 26 April 1973] 30968/73 Heading B3M [Also in Division B6] A marking machine, suitable for impressing characters in a steel sheet, includes a roll, Fig. 2, formed from a number of rings 1 having peripheral characters 2 and supported on a central shaft 3, the axis of the shaft being eccentric relative to bearing journals 4 for the roll. The rings may be located between rolls 7 which contact the surface of a sheet 8, such that the characters contact the surface for each rotation of the roll. Each ring 1 is of toothed form, Fig. 3, and has a punch 2 located in a bore in each of its teeth, the punches bearing against the central shaft and being held in position by split bushes 9. Alternatively, the rings may be of annular form, Fig. 10, and are held in place by wedges 18 which co-operate with notches 15 in the rings. The outer end of each punch may have a curved surface to facilitate clear marking. In order to change the characters to be impressed, each ring 1 is indexable about the shaft 3, suitably by a rack 40, Fig. 18, engaging with the teeth. The rack is axially moved by a piston-rod 48 coupled to cylinders 45 to 47, the combination of cylinders used depending on the number of tooth spaces the ring is to be indexed. When the positions of the rack and teeth preclude indexing in one direction, the rack and its operating assembly is pivoted clear of the ring about pivot 51, and the rack is shifted to a more appropriate position. The cylinders 45 to 47 of adjacent assemblies are staggered relative to each other to save space.  An automatic control system is used for presetting the rings to give a desired row of characters and for detecting any malfunction of the apparatus. The spacing between adjacent rows of marked characters and the thickness of the marked material are taken into account. The apparatus, Figs. 29 and 31, includes a marking roll 30 mounted in a frame 92 above rollers 76 on which a material to be marked is supported. The roll is rotated by an hydraulic or electric motor 19 through clutch parts 22, 23 and a shaft 90, the clutch parts determining the angle through which the roll rotates before marking the material. The racks 40 are movable upwardly relative to the roll about a pivot 51, and the whole assembly is vertically movable by a motor-driven screw 79 about a pivot shaft 97.

Patent GB-1120208-A (GB)
Title: A method for enriching uranium isotopes by means of ion exchange
IPC: B01J47/10
Filed: 1965-07-22
Abstract: <PICT:1120208/C1/1> A solution containing U-235 and U-238 is enriched in one of these isotopes by contacting the solution in countercurrent flow with particles of an acidic cation exchange resin on which has been adsorbed tetravalent uranium, U(IV)r.  The solution must contain hexavalent uranium, U(VI)s, and have a hydrogen ion concentration of 1N or less.  Isotope exchange occurs in which U-235 concentrates in the U(VI)s and U-238 concentrates in the U(IV)r.  As shown in Fig. 3, a natural U(VI) solution is fed into an ion exchange column down which passes resin R having U(IV) adsorbed thereon.  A part of the solution enriched in U-235 is withdrawn at 4 and the remainder is reduced to U(IV) in column 10 by zinc amalgam and HCl.  U(IV) is then adsorbed on to acidic resin R.H in column 14.  The U(IV) in the resin (rich in U-238) that has reached the bottom of the tower can be oxidized to U(VI) and optionally returned to the upflowing U(VI). There can be a succession of such towers providing further enrichment (see Fig. 5, not shown).  In Fig. 4 (not shown) a resin having absorbed thereon U(IV) is passed to an exchange column.  An oxidant/elulant solution of H2O2 + HCl, or FeCl3, is fed to the bottom of the column.  U(VI)s is formed from the U(IV)r and isotope exchange occurs. U(VI)s enriched in U-235 is removed at outlet 6.

Abstract: 715,885. Friction clutches. MONKS, H., and RUSTON & HORNSBY, Ltd. March 19, 1952 [Dec. 22, 1950], No. 31305/50. Class 80 (2) A fluid pressure actuated clutch has one clutch member moved into initial engagement with a complementary clutch member, to seal the main actuating pressure space, by an auxiliary piston after which a loaded valve shuts off the main pressure space from exhaust and opens it to the supply to fully engage the clutch. As shown a double clutch for connecting either of two gear wheels 15 of a change-speed gear to a shaft 2 comprises a carrier member 1 keyed to the shaft 2 and carrying coned clutch members 9. Complementary clutch members 12 are normally held out of engagement against spring rings 25, by a plurality of springs 20 but may be moved into engagement by oil pressure acting in spaces 19 between the clutch members and the carrier 1. Oil under pressure is supplied via ducts 26 in the shaft and radial passages 28, one for each clutch, in the carrier 1. The pressure acts initially, though a passage 29, on an annular piston 5 mounted in the carrier to move the clutch member 12 into engagement with the member 9 and seal the pressure space 19. The pressure in the passage 28 then acts on a valve 30, which moves against the action of a spring 32 to chose an exhaust port 34 and simultaneously open a supply port 33 allowing oil to flow into the space 19 and fully apply the clutch. Teeth 23, 24 slidably connect the clutch members 12 with the driven gear wheels 15. It is stated that air under pressure may be used instead of oil and that both clutches may be arranged to engage together to drive a single output member for transmitting large powers. Reference has been directed by the Comptroller to Specification 555,133.
