Title: Method of producing replicas of printing formes
IPC: G03F1/92
Filed: 1946-02-22
Abstract: 615,550. Photo-mechanical printing-surfaces; producing photographs electrically. ALLER, C. B. Feb. 22, 1946, No. 5634. Convention date, Dec. 30, 1944. [Class 98 (ii)] Replicas of printing formes are produced by placing the forme to be copied in contact with a photographic material bearing a lightsensitive silver halide emulsion, passing an electric current through the forme and said material to produce a latent faint or strong image depending on the strength and duration of the current flow, developing said image in the usual manner, and employing it to produce a printing surface in known manner. In producing replicas of planographic formes, the forme is provided with a non-conducting layer, as by inking it, on suitable parts of its surface before it is placed in contact with the copying material. The emulsion may be applied to a support which is mounted on a conducting plate forming one electrode, or the support may itself be conducting, such as a metal plate, or paper or regenerated cellulose moistened with an electrolyte or incorporating metallic or electrically-conducting material, while the forme may be a non-metallic replica, e.g. of paper, coated with a conducting layer such as powdered graphite. To make replicas of an intaglio forme or a stencil, which latter is backed by a metal plate, the electrolyticallyproduced negative is either copied photographically or reversal developed to yield a film for use in making the replica, while for a lithographic forme the water-repellent portions are covered with a non-conducting layer.

Title: Float chamber and valve assemblies
IPC: F16K31/20
Filed: 1971-03-02
Abstract: 1355073 Valves AMAL Ltd 25 April 1972 [2 March 1971 18 Nov 1971] 5797/71 and 53545/71 Heading F2V In a float chamber and valve assembly, the valve comprises first and second closure elements co-operable with respective seats axially spaced apart so that when the liquid in the chamber reaches a predetermined level the first closure element co-operates with its seat, but in the event that it does not seal properly the consequent rise in liquid level causes the second closure element to co-operate with its seat. Fuel for a domestic water heater, supplied through inlet 13, Fig. 1, and filter 15 enters float chamber 11 through valve 17 having float-actuated first and second closure elements 27, 30 respectively associated with seats 22, 23. If element 27 fails to close properly, the consequent continued rise in liquid level causes closure of the element 30. Closure of the latter is assisted by the attraction between an adjustable permanent magnet 61 and a catch plate 40. The magnet is thereafter separated from the plate 40 by a manual re-set button 58. An electromagnet may be located adjacent the magnet 61 and be energized via a thermostatic switch situated in an associated burner chimney or hot water container, so that excessive temperature causes the fuel flow to be terminated. The float lever 36 also controls a fuel shut-off outlet valve (50), Fig. 3 (not shown). A lever 47 controlled by a bellows (45) connected to a thermal control, adjusts a fuel outlet control valve (49). Rotation of handwheel 51 causes a cam surface 54 thereon to forcibly close valve 17 via plunger 55. In a "start" position of the handwheel, a plunger 56 is depressed to adjust the control valve (49) to provide increased fuel. An air-vent for a boiler, Fig. 4 (not shown), has a float-actuated valve similar to the valve 17 of Fig. 1. A float-actuated valve for a domestic header tank, Fig. 5 (not shown), employs a valve somewhat similar to valve 17 but with a first closure element of conventional flat-disc form.

Title: Electric transformers
IPC: H01F27/28
Filed: 1929-02-21
Abstract: 329,669. Smith, F. S. Feb. 21, 1929. Transformers.-The insulation of transformers is so arranged that conducting parts at different potentials are separated by layers of solid and compressed gaseous dielectric in series, the arrangement being such that dielectric stress is divided between the two layers inversely as their permittivities. In a transformer having a shelltype core 4, the low voltage winding 10 is placed around a cylinder 11 of solid insulation and is separated from the high voltage winding 20 by an insulating cylinder 15 and a layer of the gaseous dielectric with which the casing 50 is filled. The high voltage winding 20 is divided into sections spaced apart by insulating spacing washers 16 which are of corrugated form in order that in the path of steepest voltage gradient between coil sections a layer of gaseous dielectric is interposed, whilst an extended leakage path along the surface of the solid dielectric is provided. For the same reasons, a series of holes 21 are provided in the cylinder 15. The sections of the high voltage winding may be further sub-divided as shown in Fig. 4 into two concentric parts separated by a solid insulator having longitudinal corrugations to permit circulation of the gaseous dielectric. The winding is supported between end discs 25, 26 which abut against X-shaped insulators 30, 31 secured to the upper and lower frame members 2, 3 supporting the core structure. The gas employed is preferably nitrogen, or, where a large amount of heat is to be dissipated, a mixture of nitrogen and helium, the pressure being of the order of fifteen atmospheres.

Title: Improvements in or relating to Air Conditioning Apparatus
Inventor: FOWLER KENNETH JOHN VOYSEY
IPC: F24F5/00
Filed: 1968-02-07
Abstract: 1,194,472. Heating and cooling buildings. K. J. V. FOWLER. 7 Feb., 1969 [7 Feb., 1968], No. 5972/68. Heading F4U. In an air conditioning system having a number of units 11 each including a heat pump and connected in parallel and each positioned in different parts of a building which may be subject to different climatic conditions, each unit contains a control switch (21, Figs. 2A, 2B) sensitive to the pressure of the fluid flowing in the system. The system enables heat from the hot side of the building to be supplied to the cold side and vice versa so that it may not be necessary to use a boiler 14 or cooling tower 16. On starting up the system, a pump 12 causes a rise in pressure in the fluid circuits through each unit 11 whereby the switch 21 is operated, each switch being in an electric control circuit of an electric motor driving a compressor or other electrical component of each individual heat pump. Each switch 21 is connected to a delay switch and the delay of the various units 11 can be staggered. Each control circuit feeds a customer control panel containing a speed control for a fan circulating the air in each room, and a switch to change over from heating to cooling and vice versa, a room thermostat can also be provided. The units 11 are normally shut off for the night by momentarily opening and closing the switches 21 by switching off and on the pump 12. The provision of a holding relay (24) and a further thermal delay switch (25) enables an individual heater to be immediately restarted by pressing a reset button (26). An electric heater (30) may be provided and can be controlled by a thermostat in the fluid outlet path from each unit 11. This heater can boost the boiler temperature. The circuit feeding the electric heater is connected to the switch 21 to ensure that the heater is not turned on when no fluid is circulating in the system. The system could be applied to a single unit serving a number of buildings. Heat may be supplied by the boiler 14 via a heat-exchanger 13 and may be dissipated from the system by a further heat exchanger 15 and the cooling tower 16. Alternatively, heat could be taken from, or returned to a river, lake or sea. The heat pump may be of the form using thermoelectric junctions.

Abstract: 896,714. Magnetostrictive data-storage devices. WESTERN ELECTRIC CO. Inc. Feb. 23, 1959 [March 19, 1958], No. 6102/59. Class 106 (1). [Also in Group XL (b)] An information storage device comprises a magnetostrictive member 40, positioning means 51 for determining the spacing and/or polarity of a plurality of movable magnets 42-49 and thus setting up a pattern of bifurcated longitudinal magnetic fields in the member 40 in accordance with signals from a data source 50, and a read-out signal source 41. If the member 40 is sufficiently retentive the magnets need be placed only momentarily in contact with or close proximity to the member to establish a pattern of remanent magnetic induction. The read-out source 41 supplies a single current pulse which produces a circumferential magnetic field throughout the length of member 40, thus producing a torsional strain impulse in each portion of member 40 conditioned by the presence of a longitudinal field. The torsional impulses propagate in member 40 and on arrival sequentially under an output winding 12 distort the remanent circumferential magnetization to produce a sequence of longitudinal field variations which link the winding and induce voltage pulses which are passed to a utilization circuit 13. Destructive or non- destructive read-out is obtainable depending on the amplitude of the pulse supplied by source 41. In an alternative embodiment (Fig. 5, not shown), suitable for use if the member 40 has no retentive properties, the circumferential field in the region of the winding 12 is produced by a biasing source, and the data source is arranged to selectively energize a plurality of electromagnets.

[Class 40 (v).] In a screen-grid amplifier for high frequencies, the screen grid and cathode are connected to opposite ends of a bridge circuit, thus preventing a potential difference existing between the screen and the cathode due to the current flow through the inherent capacity CSA, Fig. 3, between the screen and the anode and the series-connected blocking condenser CB. The condensers C1, C2, CNS form with the inherent anode-screen capacity CSA a bridge in which CNS : CSA = C2: C1 so that the screen and cathode are at the same potential. The inherent anode-grid capacity CAG may be neutralized by the capacity CNG, while if a push-pull pair of valves is used, the inherent anode-grid capacities can be utilized as neutralizing condensers and the inherent anode-screen capacities CSA1, CSA2, Fig. 4, may form two arms of the bridge.
