Patent GB-130723-A (GB)
Title: Improvements in Acetylene Gas Generators.
Inventor: KITSON ARTHUR
IPC: C10H15/12
Filed: 1918-07-10
Abstract: 130,723. Kitson, A., and Noblett, A. July 10, 1918. Buckets, compartments, and the l i k e for solids, emptying successively.-Relates to apparatus in which a floating g a s - holder is raised by being charged with gas, and caused to rotate through a small angle by means of a helical bar passing through a slot, so that a connected part comes into position for discharging a fresh carbide-container, on the descent of the holder as the gas is withdrawn. Fig. 1 shows an elevation, partly in section, and Fig. 2 shows a plan of the apparatus. A series of carbide-containers 27 are arranged in compartments round the top of the tank 1, and are provided with release rods 36<1> which are actuated in turn by the descent of a striker 25 carried by the gas-holder 17. Each release rod 36<1> is normally held up by a spring and has a conical end which enters two partly overlapping orifices in the two spring-held parts of a latch, so that when the release rod is forced downwards, one part of the latch is moved relatively to the other, and the hinged door of the container is released. The gas-holder 17 floats in the tank 11 and carries a helically twisted bar 20 which passes through a slot in a central disk mounted on a ball race in the plate 20<1>, this central disk being prevented from rotation in one direction by means of ratchets and pawls, so that the holder is turned through a small angle on rising, but is free to descend without rotation. Excess of gas in the holder 17 is permitted to escape through the pipe 41 provided with perforations to which access is obtained through the pipe 40 when the water has sunk below its open end.

Title: Improvements in or relating to optical prisms for three colour photography and cinematography
IPC: G02B27/14
Filed: 1935-04-15
Abstract: 459,664. Colour photography ; optical systems. BELLINGHAM, L., STANLEY, F., and STANLEY, G. F., 71, Hornsey Rise, London. April 15, 1935, No. 11583. [Class 97 (i)] A prism combination for producing three parallel light beams for colour photography or kinematography contains two partially reflecting and transmitting surfaces A, B to divide two component beams from each other and from the third, and three internal surfaces E, F, G to reflect the beams in the required direction, the lengths of the several light paths through the system being equal. The part of the beam reflected by the partially metal-coated surface A of the six-sided component prism 1 suffers total internal reflection at the opposite surface C of this prism, and is then reflected out of the combination by the surface F of a triangular prism 5. The transmitted beam is totally reflected by the surface H of a triangular prism 2 on to the partially metal-coated surface B of a rhomb 3 where the beam is again divided. The reflected portion is reflected out of the combination by the surface G of the rhomb 3, and the transmitted beam, after total reflection at the surface D of a rhomb 4 is reflected out of the combination by the surface E. The three beams emerge parallel to each'other from the face Y of the combination, which is perpendicular to the entrance face X, and glass distance pieces 6, 7, 8 ensure equal light paths.

Abstract: 774,124. Liquid resistors. REYROLLE & CO., Ltd., A. April 21, 1955 [April 22, 1954], No. 11728/54. Class 37. In a liquid resistor of the type in which a central electrode is surrounded by a hollow outer electrode and the space in between is filled with electrolyte, the external shape of the central electrode in relation to that of the inside surface of the outer electrode is such that the electrodes are further apart in the region of the top of the central electrode than in the region of its bottom. The Figure shows a liquid resistor of the type used in switch gear for passing earth fault current. A cylindrical steel tank 10 has a detachable cover 11 containing electrolyte such as water with a proportion of sodium carbonate up to the liquid level indicated at 12. A vertical insulating lead in bushing 13 has a high voltage conductor passing through it supporting at its lower end a central electrode 15. The central electrode 15 comprises three cylindrical rings 16, 17, 18 of sheet steel each open at top and bottom and overlapping one another. They are of progressively increasing diameter from top to bottom of the electrode. The rings are interconnected electrically and mechanically by means of metal spiders 19 and the whole assembly is hot galvanized. The walls of the central electrode are formed with one or more openings so that the cooled electrolyte may be drawn through the openings into the region of the hot outer surface of the electrode. The central electrode may be of annular cross section and/or of frusto conical or stepped form.

Abstract: 1,013,102. Moderators; cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 27, 1963 [March 28, 1962], No. 11843/62. Heading G6C. Graphite components in a gas-cooled nuclear reactor are protected from accelerated corrosion otherwise caused by the catalytic effect of fission products on impurities in the coolant gas, by including in the graphite an inhibitor. Examples of suitable inhibitors are oxides of silicon, zirconium, beryllium and aluminium; silicon is also suitable. As an example, it is stated that 0.05% by weight of barium in the coolant gas will increase the corrosion rate due to the presence of 1 v.p.m. of carbon dioxide and water vapour by a factor of 1000 at a temperature of 1200 C. The inhibitor may be included in the material of graphite core blocks, graphite fuel cans, or within graphite fuel columns. It may be included in graphite throughout the core, or it may be limited to use within the reaction zone.

The relaxation shrinkage of a fabric sample 1, held between a fixed clip 3 and a clip 4 to which a tensioning string 5 is fastened, is measured by taking two readings of the length on the dial 9, with the sample held in tension by means of a constant-speed motor 10 and an eddy current drive 11, 12, before and after the sample has been wetted (by means of spray heads 17). During wetting the tension is relaxed. The first reading is taken for a given moisture content, controlled by an air-blower 13, heater 14 and thermostats 15, 16. After operation of the spray-heads, the moisture content is brought to the same value. The operational sequence is controlled by a uniselector with three banks of switches, the two thermostats and a thermal time-delay switch governing the steps. The first step of the uniselector is governed by a manual switch. A circuit diagram is given in the Specification.

Filed: 1938-04-25
Abstract: 499,087. Fountain pens. POLLAK, J. E. (Sagren Corporation) April 25, 1938, No. 12366. [Class 146 (iii)] In a fountain pen, collapsable - sac selffilling mechanism is provided which is normally housed in the barrel at the end opposite to the nib, and can be projected therefrom for operation. In one form, a rigid tube 10 is secured in the end of the barrel and serves as a guide for the self-filling mechanism and to provide communication between the interior of the barrel and the filling mechanism. The filling mechanism consists of a collapsable tube 14 having a covering of stiffening material and connected at its outer end with a knob 19 whereby it may be withdrawn from the end of the barrel; complete withdrawal is prevented by means of a projection 13 on the end of the tube 10. The ends of the bulb may be of increased external diameter to receive the ends of flat springs which act to restore the bulb to normal shape ; in this case the bulb may be protected by a metal gauze. In a modification, the lower end of the bulb is connected by a collapsable tube 31 to a disc 32 secured in the barrel, so that when the bulb is returned to inoperative position, communication between the bulb and reservoir is interrupted. A flat bar 40 may be attached to a spring secured to the bulb to facilitate deflation, the bar being moved to collapse the bulb when it is returned to inoperative position.
