Title: Improvements relating to Nuclear Reactors
Inventor: ACKROYD RONALD TUNSTALL
IPC: G21C7/28
Filed: 1965-12-23
Abstract: 1,161,599. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 15 Dec., 1966 [23 Dec., 1965; 11 Jan., 1966], Nos. 54509/65 and 1269/66. Heading G6C. The core of a reactor is surrounded by a reflector comprising segmental containers filled with liquid reflector, the liquid content of the containers being variable to control the reactivity. As shown, the core of a fast reactor comprises upstanding fuel assemblies 11 surrounded by segmental containers 20 within a tank 16 filled with a liquid metal coolant consisting of a lead magnesium alloy. The containers 20 are filled with the same alloy and serve as the reflector. Each container has a pipe 23 at its lower end extending almost to the bottom of a corresponding sump compartment 24 and a pipe 15 extending upwardly from the roof of the compartment to a valve 26. In one position of the valve 26 a compressed supply of inert gas, e.g. argon, is supplied to the pipe 15 to keep depressed the level of the liquid alloy n the compartment 24 and thereby support the column of the liquid alloy filling the container 20. In the other position of the valve a vent pipe 28 extending from the top of the container is connected either to an inert gas source at a pressure slightly above atmospheric or to a high pressure source of the same gas. In both instances the container is emptied of liquid alloy to reduce the reactivity but in the second instance rapid shut-down is effected. In a modification (Fig. 2, not shown), blocks of breeder material float on the alloy within the containers 20 and upon change of level of the alloy assist in controlling the reactivity. In another modification (not shown) the coolant and reflector comprise water, the water content in the containers being varied by vaporization due to heat received from the reactor core. In a further modification (not shown) the reflector liquid carries fertile material and may form a paste or slurry.

Patent GB-494144-A (GB)
Title: Improvements in the production of coloured films having a silver or silver compound sound track and apparatus therefor
IPC: G03D3/13
Filed: 1937-01-18
Abstract: 494,144. Photographic sound and picture films. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Jan. 18, 1937, No. 1462. [Class 98 (ii)] A process for producing a sound record in a combined sound and picture film wherein the pictures are produced by colour development, comprises developing the sound and picture records together, and, before removal of the silver bromide resulting from colour development, exposing either the sound track or the picture whilst the other of these areas is masked, and subsequently treating both areas in the same finishing baths. In an example, the picture and sound records are printed in known manner onto three layer material, the print is subjected to colour development, the resulting silver bleached, the sound track is given a second and masked exposure, and the print developed and fixed. The printing light for the sound track is such that the silver sound track layer is that in which the coloured sound track was first produced. In the reversal process, the second exposure is given to the picture image whilst the sound track is masked and the developed silver is removed. The silver bromide in the sound track is then exposed and blackened by a further development and the remaining silver bromide removed by fixing. If in this process the developed silver is converted into silver chloride, the exposure for the sound track light is adjusted so that it affects only the silver bromide. This conversion of the silver to silver chloride may also be applied in the negative - positive process. Another alternative in the latter process is to expose the sound track after the colour development, convert the silver from the colour development into silver bromide, and develop and fix the image in the sound track. In a modification for application to the reversal process, the sound track is masked during the second exposure and the film is developed. The residual silver bromide is converted into silver iodide and the developed silver into silver chloride or silver bromide and removed by fixing. The silver iodide, which is only sparingly soluble in the fixing. bath, remains and may form the sound track or alternatively either be developed or be blackened, e.g. by sulphiding, Renwick solution containing potassium iodide, sodium sulphite and thiosulphate may be used to form the silver iodide. The masking exposure is performed by apparatus including a drum 4 with an opaque portion 6 and a transparent ring 5, which are each transferrable for corresponding transparent and opaque rings. The ring portions are joined by a screw thread or a bayonet joint. The drum and the exposure lamp holder 7 are both immersed in liquid contained in a blackened tank 9.

Title: Improvements in or relating to shaving and other brushes, polishing pads and the like
IPC: A45D27/04
Filed: 1946-01-22
Abstract: 607,893. Self-feeding brushes or pads. GRIFFIN, P. W. Jan. 22, 1946, No. 2070. [Class 19] [Also in Group XXVIII] A container for shaving soap, polishing material or the like comprises a chamber A which may be of metal or plastic, the top of the container forming a holder P for bristles or a pad whilst the lower end consists of a knurled head F carrying a vertical screwthreaded rod H engaging in the bottom transverse wall of the holder P. The knurled head has a neck and is retained in engagement with the chamber A by spring means such as by a blade spring G in a circular groove in the inner wall of the chamber. A spring E surrounds the lower end of the vertical rod and rests at one end on the knurled head and at the other against a slide D on which bears a piston C actuated by the spindle H which may have a left-hand screwthread. The chamber has a spring-pressed valve such as a ball valve L held by a light spring M on its seat N which is pierced with a hole and connected with a tube O extending into the bristles or pad. In use, the knurled end is rotated so as to bring the piston C downward (see right half of drawing), thus forcing the spring-loaded slide down so as to sufficiently uncover a filling aperture J provided on the wall of the container so that a tube of shaving or polishing cream screwed to the aperture may be squeezed to force the cream into the space above the piston, a small air vent K being provided on the container. The knurled head is then rotated in the opposite direction to carry the piston upwardly. The coiled spring forces the-slide to follow to seal off the filling aperture, such movement of the slide being limited by a stud, snug or pin thereon coacting with a slot in the wall of the chamber or vice versa. The piston is prevented from rotation, e.g. by a stud -thereon working in a groove extending along the inside of the chamber or vice versa. Further rotation of the knurled head causes the cream to be expressed through the ball valve into the bristles or pad.
