Patent GB-730169-A (GB)
Title: Method of producing a photograph in glass and article made thereby
IPC: G03C1/76
Filed: 1953-12-01
Abstract: 730,169. Producing photographic images in glass. CORNING GLASS WORKS. Dec. 1, 1953 [Dec. 5, 1952], No. 33368/53. Class 98 (2). A photographic image is produced within the surface of a silicate glass which contains an alkali metal oxide and is free from lead oxide, by forming on such a surface a fixed silver image, heating the glass in the presence of an oxidizing medium comprising air, at a temperature between 125‹ C. below the strain point of the glass and just below its softening-point, to ionize the silver and cause the ions to migrate into the glass, and reducing the migrated silver ions to metallic silver while heating the glass in the said temperature range in the presence of a reducing medium. An ion exchange takes place between silver ions and alkali metal ions, the former migrating into the glass where they subsequently become reduced to metallic silver. The reducing medium may be an atmosphere containing hydrogen, carbon monoxide or methane, or a cuprous compound as described below. The exchange of ions is assisted by coating the image prior to heating with an argillaceous material such as ochre or bentonite (which may be partially replaced by BaCO 3 ), made into a paste with turpentine, oil of lavender or water. Such coating may contain a cuprous compound such as Cu 2 S, Cu 2 Cl 2  or Cu 2 O, or a substance which gives a cuprous compound on heating, e.g. CuS. The cuprous compound, migrating into the glass, acts as a reducing medium for silver ions as they migrate into the glass, there being no need in this case for subsequent heating in a reducing atmosphere. The oxidation reaction is also assisted by the presence of ferric sulphate, ferrous sulphate or aluminium sulphate, preferably in admixture with the argillaceous coating, and the presence of up to 25 per cent SO 2  in the air is beneficial. The SO 2  may be provided by including sulphur in the argillaceous coating. The silver image may be formed on the glass initially by applying a silver-halide emulsion layer and exposing in the conventional way or it may be transferred from a stripping film. Borosilicate glass is particularly useful in the process of the invention but other glasses may be used including photo-sensitive glass, opal glass or coloured glass. Specifications 100,738, [Class 56], 597,089 and 635,649 are referred to.

Title: Improvements in or relating to electromagnetic switching arrangements for use in electric welding machines
IPC: B23K11/24
Filed: 1934-11-20
Abstract: 447,760. Control systems for resistance welding. NEW PROCESS WELDERS, Ltd., Scotts Road, Southall, and HOHS, F. C., 8, The Green, Heston, both in Middlesex. Nov. 20, 1934, No. 33393. [Class 38 (iv)] [See also Group XXXVII] Switching control.-An electromagnetic controller for electric welding machines comprises a main contactor switch adapted to be moved to the " make " position by the pull of an electromagnet acting against a spring or weight control in combination with a self holding relay which normally connects the magnet winding of the contactor switch across the main current supply in series with a starting switch and which is arranged so that when energized it disconnects the aforesaid magnet winding so as to cause the contactor switch to open and at the same time establish a self-holding circuit which remains closed until the starting switch is opened. As shown in Figs. 1 and 3, the main contactor comprises an armature 8 carried by a pivoted carrier and adapted to be attracted to a fixed core 7 on which is mounted the energizing electromagnet 7a. The pivoted armature carrier 6 bears contact carrying arms 4 on which are pivoted contacts 3 arranged to engage fixed contacts 1 and in doing so to tilt against springs so as to have a wiping action. Within the same casing as this relay is mounted a self-holding relay, the spring-controlled pivoted armature of which carries a double contact 18, 19 engaging contacts 20, 21 in the unattracted and attracted positions. The connections to the two contactors are shown in Fig. 4, the circuit of the main contactor being first completed through a foot or hand operated control switch S and contacts 18, 20 of the self-holding relay. The main circuit to the primary P of the welding transformer is thereby closed and welding between electrodes N, N in the circuit of the secondary T is initiated. When a surge of current in this circuit occurs, indicating that the welding operation is completed, a relay M completes at contacts n, n the circuit of the coil of the self-holding relay, this circuit also passing through the switch S. The operation of the armature, however, breaks the circuit of the main contactor at contacts 18, 20 and produces a self-holding circuit through contacts 19, 21 and the switch S so that no premature reclosure of the main contactor can be made until the switch S has been released, when the parts resume their positions shown in readiness for a further operation. Specification 427,634, [Group XXII], is referred to.

Title: Improvements in or relating to Nuclear Reactors
Inventor: RAUSCH WILFRIED
IPC: G21C1/07
Filed: 1967-07-20
Abstract: 1,197,461. Controlling reactors. BROWN BOVERI KRUPP REAKTORBAU G.m.b.H. 20 July, 1967, No. 33528/67. Heading G6C. A pebble-bed reactor is controlled or shutdown by introducing neutron-absorbing rods directly into the reactor core with-displacement of the operating elements. The expression " operating elements " is a generic term for all the elements used in the reactor core, such as the fuel elements, the moderator elements, the testing elements, and the fertile elements. A roof reflector is provided above the core and has appropriate channels through which the rods pass, the rods normally being driven by pneumatic or electromagnetic drives. In the emergency shut-down of the reactor, the rods fall under the influence of gravity through the reflector to a predetermined depth in the core and are then advanced to their final position by means of the drives with the penetration resistance of the core being overcome. The advance of the rods in the core may be facilitated by reducing the resistance of the core by changing its geometry, e.g. by the removal of one or more of the operating elements and the subsequent return of the elements by means of a circulating device connected to the core through a supply channel. During insertion the rods may be caused to vibrate. As shown in Fig. 2, the preferred control rod 4 consists of a carrier tube 8 surrounded by a neutron absorber layer 9 which is clad with an outer sheath 10 of high temperature-resistant steel. The outer sheath 10 has a pointed penetrating tip 11 in the shape of a rounded cone. Perforations 12 are provided in the zone of the conical tip, from which perforations cooling gas from the internal tube passage 13 passes through the perforations 12 to the fuel. Additional perforations may be disposed in the wall of the rod so that when the rod has been completely introduced, some of the perforations are above the surface of the fuel while the remainder are within the fuel. With such a construction, the pressure drop of the cooling gas over the length of the introduced length can be utilizing for allowing a part of the cooling gas to flow through the internal passage 13. As long as the rod is outside the core there is practically no flow of coolant whilst with the rod completely introduced the desired maximum cooling effect is achieved. The control rods may be circular in cross-section or of such a cross-section that a multiplicity of grooves are formed on the outside surface. The rods may be provided with external cooling ribs. Test elements, irradiation samples &c. can be placed directly into the control rods and introduced into the core.

Title: Improvements relating to Washing Machines.
Inventor: SEARLE WALTER WILLIAM RALPH
IPC: D06F34/06
Filed: 1966-07-27
Abstract: 1,190,568. Washing machines. HOOVER Ltd. 11 July, 1967 '[27 July, 1966], No. 33788/ 66. Heading D1A. A washing machine has a timer controlling a sequence of operations including two timed pumping periods during the first of which a level responsive device is actuated at a predetermined level which actuation does not affect the continuation of the pumping but which must take place for the second pumping to occur. The washing machine has a horizontal perforated drum mounted in a tub and rotatable about a. horizontal axis at low and high speeds for washing and 'spin-drying. The tub is filled through a solenoid operated water valve and emptied by pump 9 with its own electric motor. The timer 12, which includes a cam 10 driven by a stepper, is energized through contacts T when closed and a resistor 13 and continues to run until a definite time has expired or a predetermined temperature or water level has been reached when the cam is stepped onto the .next position by the stepper which operates when 'resistance 13 is short-circuited. Pairs of contacts 16, .17 or 18 corresponding to times of 20 seconds, 2 minutes and 4 minutes respectively are connected in series with contacts 19, 20, 21 associated with a common contact C. If in any cam position contacts 16, 18 are open and contacts 17 closed, contact 19 engages contact C after 20 seconds but nothing happens as contacts 16 are open. However after 2 minutes, when contact 20 engages contact C as contacts 17 are closed resistance 13 is short circuited to step the cam on. If all contacts are open stepping will not take place until some predetermined condition obtains when resistance 13 will be short circuited. Contacts W in series with water valve WV are .also connected 'to a contact Z of a level responsive device 25 having a common contact A and a 'full" contact X. When the tub is empty, contacts A, Z are connected and if contacts W are closed valve WV is opened. A printed circuit has annular surface sections T, d, e, f, g, h, i, k, E and F which at various positions of cam 10 are placed in contact with bus-bar 26. When the machine is full and contacts A, X are bridged valve WV is closed and resistance 13 is short circuited through printed circuit section F so that the cam is stepped onto a further operation. At three cam positions during the programme - (18), (28) (35) (Fig. 2, not shown) if the pumping has taken place fully at the preceding position (17), (27), (34) so that contacts A-Z are bridged, then the cam is stepped straight .on to the succeeding position viz. (19), (29) or (36) and the programme continues whereas, if the contacts A-Z are not bridged the cam stops at the position (18), (28) or (35), Thus if the pump becomes stalled at any point, it will not remain energized sufficiently long to 'be damaged.

Title: Improvements in or relating to the operation of gun-cocking mechanisms
IPC: F41A7/04
Filed: 1936-12-09
Abstract: 481,313. Controlling aircraft machine guns; valves. DUNLOP RUBBER CO., Ltd., WRIGHT, J., and TREVASKIS, H. Dec. 9, 1936, No. 33792. [Class 92 (ii)] [Also in Groups XXVIII and XXIX] Hydraulic apparatus for selectively controlling the operation of the cocking mechanisms of a number of machine guns on aircraft includes a multiple-way valve in the form of a disc 25, Fig. 1, which is rotatable to register with a disc 23 in a number of positions to admit pressure liquid to any one mechanism, to groups of mechanisms, or to all the mechanisms. The disc 25 is rotated by a handle 4 having a spring detent 6 which registers the handle in the eleven positions 8 to 18 shown in Fig. 2 to effect the cocking of the several guns or groups of guns as marked. The fixed disc 23, Fig. 4, has eight apertures 24(a ... h) connected to pipes 28 leading to four port and four starboard guns. The rotary disc 25, Fig. 5, has apertures 26(a ... h) corresponding to the apertures 24(a ... h) and four additional apertures 26(k ... n) at radial distances from a central port 27 corresponding to the radial distances of the fixed apertures 24(can ... h) from the supply port 20. All the apertures in the rotary disc are connected to the central port 27. The position shown in Fig. 5 for the disc 25 corresponds to the position 10 of the handle 4 and clockwise rotation from this position to positions 8 to 18 and 9 produces the selection of guns marked in Fig. 2. After rotation to the selected position, pressure on a spring- controlled knob 30-causes a plunger 29 carrying balls 37 to move downwardly and exert pressure on a spring 32 which presses the discs together, the balls 37 being forced radially by a second plunger 35 to engage fixed recesses 38 to lock the discs together. Pressure in the pipes is produced by a hand-pump, Fig. 6, supplying the port 20 in the fixed disc 23, the pressure acting also on the lower end of the plunger 35 to release the discs if the pressure is excessive. The pump, Fig. 6, is double-acting, being operated by a handle 43 engaging between the plungers 44, 45. The chamber 56 is supplied with liquid by a port 60 and the liquid enters a pump chamber 53 by a port 58 when the plungers move to the right. Return of the plungers causes the liquid to be forced by way of valve 48 to a passage 54 leading to the passage 19 in the selector valve. The pump chamber 49 then fills with liquid which on return of the plungers is forced past valve 50 into the passage 54.

Title: Improvements in or relating to oil stoves
IPC: F23D5/00
Filed: 1958-10-22
Abstract: 857,735. Supplying fuel to burners. LINDE, R. VON Oct. 22, 1958 [Oct. 22, 1957], No. 33833/58. Class 75(1). In an oil stove having a vapour burner 2 an oil container 3 from which oil flows through a regulator 20 to the burner contains a pump 6 delivering the oil from a tank (not shown) to the container 3, and means are provided to control the pump delivery so as to maintain a constant level of oil in the container 3. When the pump is started oil is sucked from the container 3 through passages 15, 16 and is forced into a chamber 17 and through a spring loaded ball valve 18 back to the container 3. The pressure in the chamber 17 moves a diaphragm 13 downwardly to actuate a valve 14 which closes the passage 15 and puts the passage 16 in communication with the pipe 7 from the oil tank (not shown). When the desired level of oil is reached a mercury switch 9 on a float 8 is opened to de-energise the motor 5 driving the pump. A safety switch 11 also controlling the motor is mounted on a float 10 disposed in a compartment formed by a partition 12 which extends above the proper level of the oil in the container 3 ; oil overflowing into the compartment misses the float to operate the switch 11. In a modification the motor also drives a blower supplying combustion air and the mercury switch controls a solenoid valve in the supply pipe 7 instead of controlling the motor. In a further modification the pump forces oil through a pipe to a receptacle located above the level of the burner and the oil then flows through a further pipe from the receptacle to the oil container. A float actuated mercury switch de-energises the motor when the proper level in the container is reached. In a still further modification the oil container itself is located above the level of the burner. In order to prevent oil flowing under gravity from the oil tank through the oil container to the burner when the pump is stopped a ball valve is located in the inlet or outlet to the pump and is operated by pump suction or pressure. A bimetallic or photo electric or thermo electric element may be arranged to de-energise the motor when the burner flame is extinguished.
