Title: Improvements relating to relay valves
Inventor: DYSON ERNEST FREEMONT
IPC: F16K31/12
Filed: 1954-11-01
Abstract: 760,095. Fluid-pressure servomotor-control systems. BRISTOL CO. Nov. 1, 1954, No. 31518/54. Class 135. A valve for controlling the flow of fluid from a source 12 to a conduit 14 leading to a fluidoperated motor 16 in response to variations by independent control means 47 of the flow of a relatively small volume of the fluid from the source to the atmosphere at orifice 42, comprises a body 20 having a bore with, e.g., spaced ports 25, 27 communicating with the conduit and the atmosphere respectively, movable means, e.g. a piston 21 in the bore with one end exposed to the pressure from the source and the other end defining a variable volume space between the piston and the orifice and allowing communication between the source and the conduit when the piston is in one position and between the conduit and atmosphere in another position, and elongated capillary tube means 40 providing restricted communication between the space and the source. A spring 41, co-operating with pressure in the space, tends to move the piston towards the position in which the conduit 14 is connected to atmosphere. The diaphragmoperated valve 16 may be controlled by a process cycle controller or a thermostat actuating a hinged valve 47, a rotary edge cam or a rotary disc valve controlling the nozzle.

Abstract: 1186351 Metering ENGLISH ELECTRIC CO Ltd 30 June 1967 [14 July 1966] 31570/66 Headings G4D D6Y D1D9E and D6C1 Apparatus for summing electrical signals occurring at a plurality of sources comprises stores 16A, 16B, 16C, 16D, Fig. 1, transmitters 14A, 14B, 14C, 14D for transmitting signals from the sources to the associated stores, each transmitted signal being transmitted as a.D.C. level. A scanner 22 sequentially reads-out the stores so that the signals stored therein are accumulated in a counter 12. In the  embodiment described for transmitting signals from electricity meters, two toothed wheels on the shaft of each meter rotate in the gaps of two transformers (T2, T3), Fig. 4B (not shown) so that when a tooth enters the gap of a transformer the amplitude of oscillation of an associated oscillator (68, 70) is altered to switch a bi-stable circuit (72) from its one stable state to its opposite stable state so that as each unit of electricity is used a negative signal is induced on the associated transmission lines 34A, 34B, 34C or 34D, Fig. 1. At the associated store, Fig. 2 each negative signal on line 34A cuts-off transistor TR 1 and so renders transistor TR2 conducting to produce a positive-going signal across resistor R8 which is transmitted via capacitor C4 and diode D1A to an associated register 18A, Fig. 1. As the shaft of the electricity meter rotates the negative level is removed from line 34A so that when a scanning pulse is received on line 24, Fig. 2 transistor TR1 is rendered conducting and transistor TR2 cut-off so that a signal is transmitted via capacitor C2 and diode D2A to the counter 12, Fig. 1. The scanner 22 comprises a ring counter incorporating two bi-stable circuits. If one of the meters requires to measure twice as much energy as the other before giving a negative output signal its output line e.g. the output line 34A may be connected through an inverter 41, Fig. 1 to a further store 16A' to which is also connected an output of scanner. Pulses are then accumulated in the counter 12 from the first store 16A when a negative signal exists on line 34A and from the second store 16A' when a positive signal exists on line 34A.

Abstract: 631,922. Moulding tubes of thermoplastic material. EVERETT, S. J. Nov. 28, 1947, No. 31578. Drawings to Specification. [Class 87 (ii)] [Also in Group XXIII] Relates to the imparting of a finely finished internal surface and accurate bore to tubes of thermoplastic material used for example for hypodermic and similar syringe barrels. Tubing having a bore of diameter slightly less than that required in the finished product is placed over a mandrel having, at the starting temperature, a diameter less than the bore of the tubing and made of a material having a high coefficient of expansion relative to that of the thermoplastic material. The tubing and mandrel are heated together by passage through a furnace to a temperature at which the thermoplastic material softens, and the mandrel, by reason of its greater expansion, stretches the tubing to the required diameter which it retains on cooling. The stretching may be effected in two or more stages using mandrels of slightly different diameters. Different materials may be used for the different mandrels, e.g. the steels known by the Registered Trade Marks " Staybrite " and " Stellite." In the case of short tubes the tubing is arranged on vertical mandrels ; longer tubes are positioned on horizontal mandrels. Transfers or other graduations or markings, in relief or intaglio, may be applied during heating and stretching.

Title: Method and means for producing a mixture of air and combustion products to be used for combustion in furnaces provided with rotary air preheaters
IPC: F23M20/00
Filed: 1926-12-20
Abstract: 263,492. Aktiebolaget Ljungstr÷ms Angturbin. Dec. 22, 1925, [Convention date]. Combustion products, returning to furnaces; steam and water, supplying. - In furnaces employing rotary regenerators the air is preheated by mixing it with flue gases taken from the gases leaving the regenerator. Fig. 1 shows a rotary regenerator of the kind described in Specification 162,250 in which the fan 10 for supplying air through the regenerator draws combustion products from the waste gas outlet 14 through a pipe 16 and forces the air and gas mixture through the regenerator to the furnace. The pipe 16 is provided with a damper 18 for controlling the amount of waste gases supplied. The closing of the damper 18 simultaneously opens an air inlet 19 to prevent a vacuum in the portion of the pipe 16 adjacent to the fan 10. According to the Specification as open to inspection under Sect. 91 (3) (a), instead of adding the hot flue gases to the cold air, the air after being heated in the regenerator may be diluted with flue gases which have or have not passed through the regenerator. Instead of flue gases, steam or water may be added to the air. This subject-matter does not appear in the Specification as accepted.

Title: Manufacture of blue vat-dyestuffs
IPC: C09B7/06
Filed: 1923-12-22
Abstract: Thioindigoid dyes are produced by halogenating the 2 : 3 : 21 : 31-bis-naphthothiophene-indigo or the dyestuffs made by condensing 2 : 3-naphthoxythiophene with reactive a -derivatives of isatin; or, similar products are obtained by condensing suitable components one or both of which contain halogen, that is, by condensing (a) halogenated 2 : 3-naphthoxythiophenes with nonhalogenated isatins or 2 : 3-naphthioisatins having reactive a -substituents, (b) non-halogenated 2 : 3-naphthoxythiophenes with nuclear halogenated isatins, or 2 : 3-naphthioisatins having reactive a -substituents, (c) halogenated 2 : 3-naphthoxythiophenes with nuclear halogenated isatins or 2 : 3-naphthioisatins having reactive a -substituents. The halogenated 2 : 3 : 21 : 31-bis-naphthothiophene-indigos may also be made from halogenated 2 : 3-aminonaphthoic acids; when starting with the 1-halogen compound, for instance the 1-chloro-compound, it is first converted into 1 : 2-dichloro-3-naphthoic acid by Sandmeyer's reaction, condensed with thioglycollic acid, and the 1-chlornaphthalene-2-thioglycollic-3-carboxylic acid converted by the usual methods to the corresponding oxythionaphthene which is then oxidized to the dyestuff; an example is given in which the ring closure is effected with acetic anhydride.  The products dye cotton from the vat in indigo-blue shades fast to chlorine, kier-boiling, and light; they may also be printed on cotton.  The condensation of a halogenated 2 : 3-naphthoxythiophene with an a -anil or an a -halide of 2 : 3-thionaphthisatin, and the halogenation of 2 : 3 : 21 : 31-bis-naphthothiophene-indigo or of 2 : 3-naphthothiophene-2-indol-indigo when prepared by the method claimed in Specification 219,280 are excluded.  According to examples (1) 2 : 3-naphthioindigo is brominated in nitrobenzene or sulphuric acid, and chlorinated to a dichlor derivative in sulphuric acid in presence of iodine, or to a monochlor derivative by means of sulphuryl chloride in chlorobenzene; (2) 2 : 3-naphthoxythiophene is condensed with 5 : 7-dibromisatin-a -chloride and the product further brominated or chlorinated; (3) 1-brom-2(S)-3-(CO)-naphthoxythiophene is condensed with 5 : 7-dibrom-or 5 : 7-dichlorisatin-a -chloride; (4) the dyestuff from 2 : 3-naphthoxythiophene and isatin-a -chloride is brominated.  1-Halogen-2 : 3-aminonaphthoic acids are obtained by acetylating 2 : 3-aminonaphthoic acid, halogenating, and saponifying; chlorination by means of hydrochloric acid and sodium chlorate is described.  Halogen-2 : 3-naphthioisatins may be prepared from halogen-2 : 3-naphthoxythiophenes by the methods described in Specification 28240/06.

Title: Improvements in colour photography
IPC: G03C7/20
Filed: 1936-11-25
Abstract: 485,862. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES. Nov. 25, 1936, No. 32273. Convention date, Dec. 7, 1935. [Class 98 (ii)] Separate colour-record images are produced from material having three superimposed layers containing latent colour-record images on a single support, or two superimposed records on one support and a single layer on a second support, the superimposed layers being separated by intermediate layers impermeable to some developers and permeable to other developers or capable of being rendered permeable to other developers by subsequent treatment, by separately developing the several colour-record images and producing the separate colour-records therefrom. For example, if a three layer material is provided with intermediate layers impermeable to alkaline and acid developers respectively, the top layer may bo developed by means of an alkaline developer, copied, and stripped off with its intermediate layer, the second layer then developed with an acid developer, copied and stripped off, and the bottom layer finally developed. Alternatively, the three layers may be separately developed and toned or coloured, copying being effected by coloured lights. In an example, a support carries superimposed blue- and green-sensitive layers separated by a layer impermeable to an acid developer. A red-sensitive layer is provided on a separate support. After exposure, the image in the green-sensitive layer is developed with an acid developer, e.g. a ferrous oxalate developer and copied by light having no blue component onto red- or green-sensitive material. The upper layer is then removed mechanically or chemically and the image in the blue-sensitive layer is developed with an alkaline developer. The image in the red-sensitive layer is developed in the ordinary way. Specification 461,559 is referred to.

Abstract: 784,395. Batteries. YARDNEY INTERNATIONAL CORPORATION. Nov. 20, 1953 [Nov. 22, 1952; Sept. 28, 1953], No. 32298/53. Class 53. Electrodes comprising a grid pasted with silver oxide, zinc or other active materials are formed from the corresponding metals or oxides by electrolytic oxidation or reduction before the electrodes are assembled in the battery. Electrodes comprising reduced metals are washed and dried by heating in a non-oxidizing atmosphere. A zinc electrode, Fig. 3, may consist of a network of zinc and silver wires pasted with zinc oxide mixed with a solution of potassium hydroxide, some of the silver wires 13 being brought out through a rubber sleeve 20 to form a terminal. The pasted net is made the cathode in a caustic potash bath, the anode being of nickel, stainless steel, or other inert material, the two electrodes being subjected to pressure against spacers placed between them. The current passed through the bath may be double the normal charging current of the finished accumulator. When the reduction of the zinc oxide to zinc is completed the electrode is washed and dried between two electrically heated plates which are sufficiently close together to ensure that the electrode is enveloped in live steam with the exclusion of air. Fig. 5 shows an alternative form of grid having perforations 112 at an angle to the face of the grid which is filled with comminuted silver, silver oxide or zinc oxide which may be in the dry condition or in the form of paste. Paste applied to the grid may be pressed into the openings by pressure applied to sheets of blotting paper on both sides of the grid which may be made of silver. The grid is then subjected to electrolytic oxidation or reduction, and if the filling consists of comminuted silver it may first be sintered. The terminal lug 116 is formed by a continuation of the unperforated part 115 of the grid.
