Title: Improvements in or relating to methods of electro-deposition on p-type germanium
IPC: C25D3/56
Filed: 1964-03-02
Abstract: P-type germanium which may be doped with indium, is plated with lead, antimony or an alloy thereof by first giving a flash coat of black porous antimony using a potential below that at which gas is generated but above the saturation potential of antimony, and then plating grey antimony and/or lead at normal potentials.  The electrolyte for the flash coat contains 15-19 g per litre of KSb tartrate, 15 to 52 g citric acid and 37 to 195 g sodium citrate, adjusted to a pH above 6, and under these conditions black antimony is deposited at -850 to-950 MV, and a current density of .28 A/S.Dm. A graph is given.  If a potentiostatic device is used to control deposition of black antimony, the conductor lead to germanium should be of low resistance e.g. secured by indium and copper deposited on the germanium. The second plating may be partly Sb, partly Pb-Sb alloy.

Title: Improvements relating to nuclear fuel processing
Inventor: HARTLEY KENNETH
IPC: G21C19/48
Filed: 1962-03-08
Abstract: 977, 566. Processing spent nuclear fueL UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 26, 1963 [March 8, 1962], No. 8894/62. Heading G6R. During a process for recovering fissile ceramic material from a non fissile matrix, such as a cermet fuel, the ceramic is separated from the matrix by heating a portion of a quantity of bulk fuel in an inert atmosphere to a higher temperature than the melting point of the matrix, propelling the heated material away from the bulk, and breaking it up whilst it is cooling. In the embodiment described, complete stainless steel clad cermet fuel elements are broken down, the cermet comprising uranium dioxide (possibly mixed with plutonium oxide) in a stainless steel matrix. The method results in a mixture of matrix spheres of low ceramic content and ceramic spheres. The fuel may be heated by high frequency induction, oxy-acetylene flame, or plasma jet. The heated material is removed by gravitational fall, or by being propelled laterally or upwardly by an inert gas flow. The breaking up of the heated material is effected mainly by its movement, but may be assisted by impact with cooled surfaces whilst the matrix is still molten, or by contact with surfaces not specially cooled after the matrix has frozen. To assist in cooling the particles, a fluidised bed may be formed in conjunction with the inert propelling gas. If the matrix is magnetic, a magnetic field may be utilized to achieve lateral separation of the matrix and fuel particles. In the drawing, a metal spray gun 1 has a complete fuel rod 3 fed into it. The gun nozzle 7 injects the molten matrix and heated ceramic into spray chamber 8. In addition to the gun combustion gases, an inert gas may be fed through the nozzle 7 to act as a carrier. The main propulsive gas, argon or nitrogen, enters the spray chamber through a nozzle 9. The separated and cooled particles are conveyed to a cyclone separator 11, which separates the gas from the particles. Specification 841,860 is referred to.

[Class 79 (iii)] [Also in Groups XXVI and XXXIII] An engine mounting comprises at each attachment point a bearer mounted in a spherical bearing g carried by a fixed portion of the structure, and a swinging cramp m having a wide base and an adjustable ball-ended bolt o at its upper end, while secured to the engine in a corresponding position is a cross piece w, Fig. 3, or s, Fig. 9, formed with a spherical cup y to receive the ball end of the bolt o. Fig. 1 shows an arrangement of four attached feet for an aero-engine in which the port rear foot a is fixed, the starboard rear foot b is capable of lateral but not fore-and-aft movement, and the front feet c, d, are capable of both lateral and fore-and-aft movement. The front mountings c are as shown in Fig. 3, a boss t bolted to the underside of each foot resting on the flat upper surface of the bearer j, to allow sliding movement in any direction. The mounting for the starboard rear foot b is shown in Fig. 5, a tapered spigot 23 below the foot engaging a tapered socket 21 in the bearer j, the socket being elongated in the lateral direction, while in the case of the mounting for the port rear foot a, shown in Fig. 9, the tapered spigot 26 engages a conical socket 25 in the bearer j. In both rear mountings the bearer is split along its transverse diameter. The form of cramp shown in Fig. 9, in which the bolt o is inclined to the vertical and engages with a projection 27 on the lower cross-piece s, is applicable where projections on the engine foot prevent the use of the C-shaped cramp shown in Figs. 3 and 5. Resilient strips v, r, may be provided at the lower and upper bearing surfaces of the engine feet.

Title: Process and device for fibre-coating materials and objects
IPC: B05C19/00
Filed: 1950-04-12
Abstract: 691,061. Fibre coating articles. HUG, A. R. April 12, 1950. [April 14, 1949 ; July 5, 1949 ; Sept. 11, 1949] No. 9054/50. Class 93. Articles are fibre coated by the use of an electric field which moves fibres from a container to the article, the article being provided with adhesive to hold the fibres thereto and during the fibre-coating one pole of the voltage source generating the electric field is constantly conductively connected to the article while the other pole is constantly conductively connected to the fibre container. As shown, current from the mains passes along cable 12 to rectifier 112, one pole 16 being connected through connection 18 to object 17 and the other pole to the base 191 of fibre container 19, so that an electric field is produced between the base 191 and object 17 thus causing the fibres to move to the object. Since the current is of only a few milliamperes the human body may serve instead of connection 18, one pole of the potential source being grounded and the object being moved towards the other electrode by. hand until the fibres jump across to the object. Modifications include a continuous fibre-coating process and the coating of walls and large sheets with fibres.

Abstract: 550,953. Pressure gauges. BENDIX AVIATION CORPORATION. July 28, 1941, No. 9593. Convention date, June 25, 1940. [Class 106 (ii)] Comprises a chamber or casing in restricted communication with the outside atmosphere or otherwise substantially airtight with respect to the outside atmosphere and an element responsive to the differential in pressure within and without said casing wherein means effective during rapid temperature changes exterior to the casing modifies the rate of change of temperature within the said casing. In the rate of climb indicator shown in Fig. 3 the frame is formed by rear and face plates 10, 11 held by spacers 12. The diaphragm 14 is supported by a central boss 23 secured to an arm 15 supported at one end by a bracket 16 secured to the plate 10 and at the other end engaged by a coned screw 21 by which zero adjustment is effected. The hollow boss 23 and diaphragm 14 is connected by a pipe 25 with a coupling chamber 26 vented to the outside atmosphere through the casing 40. Movement of the diaphragm is transmitted by link 27, rock-shaft 28, arm 29 and pin 30 to a spindle 31 and subsequently by rod 34 and pinion 35 to the spindle of pointer 38. A hair spring 39 is provided. The mechanism is inserted in a sealed casing 40. The chamber 26 is flanged at 47 and secured by screws 48 to the casing and communicates with the exterior by a threaded passage 50 adapted to receive a nipple 51. Diffusion means of the type disclosed in U.S.A. Specification 2,147,962 provided restricted communication between the inside and outside of the casing. For instance a hollow member 52 is coupled to chamber 26 and closed at one end by a butt-ended porcelain tube 53 which controls diffusion between the member 52 and the casing, while another similar porcelain tube within the member 52 closes the other end and controls diffusion between the member 52 and the outside atmosphere. A temperature controlled byepass valve 54 is controlled by an adjustable temperature sensitive element 55. The bottom portion of the casing 40 is formed with a recess 57 to receive a container 58 for enclosing a mixture possessing a high'latent heat of fusion such as a mixture containing 55 per cent of mercury and 45 per cent bismuth which acts to decrease the rate of change of temperature within the casing thus obviating the pressure differential due to this cause that would occur without the mixture.
