Abstract: 1,117,194. Electric hoists. GEO. W. KING Ltd. 3 Feb., 1967 [11 Feb., 1966], No. 6247/66. Heading B8B. In an electrically operated hoist or pulley block incorporating a slipping clutch between the driving motor and the winding drum or sprocket 10, a pawl 18 is provided to engage a recess 17 in the drum 10 at predetermined limits of wind. Fig. 2 shows the device operating to brake the drum 10 at a lower limit of wind of a load on a cable 30. In this condition, the cable 30 having one end anchored to a resilient mounting 27, engages a freely rotatable bobbin 25 on a sliding actuating member 20 and causes the latter to move upwardly against a spring 22 at the limit of wind. The member 20 passes through an aperture in the pawl 18 and has an angled section 20a which slides the pawl 18 into the drum locking position upon said upward movement. With upward movement of a load on the cable 30, the member 20 returns under spring pressure to its lower position and the drum is unlocked. The drum is stopped at an upper limit of wind by a block on the cable engaging a spring-loaded pawl and pushing the latter into engagement with a further recess on the drum. The pawls may be set into operation to stop the drum by direct or inclined contact with a cable guide moving axially of the winding drum.

Title: Improvements in or relating to a process for the treatment of an aqueous homogeneousnuclear reactor fuel
Inventor: GLUECKAUF EUGEN
IPC: G21C19/50
Filed: 1956-02-29
Abstract: Fission products are removed from a nuclear reactor fuel comprising a homogeneous aqueous solution of uranyl sulphate by adding to the solution a chemical substance which increases the rate of formation of a separate phase containing the fission products.  Addition of a sulphate of cerium, aluminium, chromium, or iron assists the precipitation of rare earth sulphates; the rate of precipitation of fission product strontium and barium sulphates is increased by adding barium sulphate.  To remove halogens, silver sulphate, with or without iodine, is added to precipitate silver halides; alternatively iodine may be separated as a gaseous phase by feeding a gaseous stream of natural iodine through the solution.

Patent GB-356657-A (GB)
Title: Improvements in or relating to shock absorbers
IPC: F16F9/26
Filed: 1930-03-03
Abstract: 356,657. Hydraulic shock-absorbers. WAHL CO., Chicago, U.S.A. March 3, 1930, No. 6897. Convention date, March 1, 1929. Void [Published under Sect. 91 of the Acts]. [Class 108 (iii).] In a double-acting hydraulic shock-absorber in which an operating lever projects through the side of the cylinder between two opposed pistons which are urged into contact with the lever by springs abutting against the end covers of the cylinder, the ends of the cylinder are connected by a passage having a tapered regulating valve and also provided with means for byepassing some of the liquid. The double-ended cylinder 2, Figs. 2 and 3, is formed with an upstanding central part which carries the bearings for the operating shaft 26 and serves as a reservoir communicating with the space between the pistons 5. The end of the operating lever 25 is rounded to engage the pistons which are forced up by springs 8, 9 bearing against the screwed cylinder caps 6, 7. One-way ball valves 14, 15 ensure the supply of liquid as required from the central reservoir to the ends of the cylinder which are directly connected by the passage 40 having an arrangement of valves shown in the enlarged sectional view, Fig. 4. These valves are designed to prevent hissing of the apparatus by avoiding the passage of liquid past sharp edges while passages controlled by ball-valves may be provided to obtain a differential effect and relief valves controlled by springs also serve to avoid excessive pressure at either end of the cylinder. In a cylindrical cavity arranged at right-angles to the passage 40 is disposed a block 42 having a tapered needle or throttle valve 45 which may be screwed in or out to vary the flow of liquid in either direction. Liquid may also flow through the passages 56, 57 which are controlled by a ball 70. This ball prevents flow in one direction but allows a limited flow in the opposite direction. The ball is very slightly less in diameter than the cylindrical hole in which it is located and a thin film of oil thus leaks through the space between the two in such a way as to avoid hissing. The ball 70 and the loose locating pin 71 are carried in a separate block 64 which is pressed against the block 42 by a spring 68 acting on the closing disc 66. In the event of excessive pressure at either end of the cylinder the block 64 momentarily moves away from the end of the block 42 and allows escape of liquid. Several modifications of the liquid throttling arrangements are illustrated.

Abstract: 558,424. Thermal switches for discharge lamps. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 26, 1942, No. 7149. Convention date, May 24, 1941. [Class 38 (v)] [Also 'n Group XL] In a thermal switch, for starting a discharge in a discharge lamp an increased delay action and quick break are obtained by the contacts being held together magnetically, e.g. by a fixed magnet 41 attracting an armature 43 on a member 45 carried by the bimetallic strip 29 which also carries the moving contact 27. When a switch 21, Fig. 6, is closed current passes to the electrodes 16, 17 of the discharge lamp 12 through a resistance 18 arranged inside the U of the bimetal strip so that after a time interval the contacts 26, 27 open suddenly to cause a surge to start the lamp. The current still passes through the resistance 18 and the contacts remain open. In a modification, a thermal switch with normally closed contacts is connected in series with a glow discharge switch thus producing a double delay, Fig. 10 (not shown). Specification 533,249 is referred to. The Specification, as open to inspection under Sect. 91, also describes a construction, Figs. 11, 12, (Cancelled) in which the bimetallic strip 230 carries a permanent magnet 290 which cooperates with a fixed permanent magnet 300. The contacts are normally open and the bimetal is heated by a glow discharge which causes the contacts to engage. This subject-matter does not appear in the Specification as accepted.
