Title: Thermally insulated structure for storage and transportation of a cold liquid
IPC: F17C3/02
Filed: 1961-01-09
Abstract: 900,268. Storing liquefied gases. CONCH INTERNATIONAL METHANE Ltd. Jan. 9, 1961 [May 27, 1960]. No. 795/61. Class 8(2). [Also in Group XXXIII]. A thermally insulated structure, for example forming part of a tanker, for the storage and transportation of a cold liquid having a boiling temperature considerably below the ambient temperature, e.g. liquefied natural gas comprises a primary container 22 of large capacity mounted within a metal housing 40, e.g. the inner hull of the tanker, which lined adjacent its inner surface with a thermal insulation, the latter comprising the combination of a primary layer 42 of a porous insulating material, e.g. balsa wood or foamed plastic material, mounted on the wall of the housing 40 and having the ability to resist penetration of the cold liquid in the event of failure of the container 22 and a secondary layer 50 of a thermal insulating material, e.g. diatomaceous earth or glass wool fibres, incapable of resisting penetration by the cold liquid and positioned inwardly of and supported adjacent to the primary layer 42. The primary layer 42 may have an interconnected pore structure if it is sealed to the housing 40 and if the vapour permeability of the pores in the vertical direction is less than the amount of vapour made available by the cold liquid penetrating the insulation; the entrapped vapours in this case provided an insulation layer between the housing 40 and the penetrating liquid. Alternatively, the primary layer 42 may have a disconnected pore structure so that the cold liquid will be unable to penetrate into the layer. Inwardly of the secondary insulating layer 50 there is provided a protective wall of plywood panels 44 which may be supported on wooden struts 46 fixed to the layer 42 or extending therethrough and fixed to the housing 40. The container 22 is supported upon a flooring 52 having an upper layer of hard wood 54, e.g. plywood, and where a plurality of containers are disposed in the inner hull of a tanker they are secured by top and bottom keys fitting slidably within associated keyways to stabilize the position of the containers while allowing them to contract and expand, Fig. 3 (not shown). The inner hull of the tanker is spaced from the outer hull and fluid is circulated therebetween to minimise transfer of cold to the outer hull in the event of failure of the insulation. In a modification, Fig. 2 (not shown) a wall of plywood panels is mounted by means of firring on the housing 40, the primary layer of insulating material being sealed to the inner side of the panels and the space between the housing 40 and the panels being filled with fibrous or particulate insulating material. The inner surface of the primary insulating layer is protected by further panels of laminated paper, metal or plywood coated with synthetic resin against which is located the secondary insulating layer faced with a further wall.

Title: Process for the manufacture of new dyestuffs of the phthalocyanine series
IPC: C09B47/067
Filed: 1936-01-09
Abstract: Phthalocyanines are prepared by an improvement in the process described in the parent Specification which consists in heating o-dinitriles of compounds of the formula <FORM:0470499/IV/1> where X is --O-- or --CO-- preferably in the presence of heavy metals, such as copper, nickel or cobalt, or their salts, ammonia or ammonium salts, or alkali or alkaline earth metals in the presence of higher alcohols.  In place of the o-dinitrile substances giving rise to them in the course of the reaction may be used.  Examples are (1) heating 2 : 3-dicyanogen-diphenylene oxide with cuprous chloride, benzophenone and pyridine; (2) heating 2 : 3-dicyanogen fluorenone with cuprous bromide and quinoline.  The products may be sulphonated and converted into lakes.  The 2 : 3-dicyanogen-diphenylene oxide is obtained from 3-amino-diphenylene oxide by sulphonation, substitution of the amino group by a cyanogen group by Sandmeyer's reaction, followed by sublimation of the sodium salt with potassium ferrocyanide. The 2 : 3-dycanogen-fluorenone is obtained in analogous manner.

Title: Vehicle wheel brake actuators
IPC: B60T17/08
Filed: 1973-01-05
Abstract: 1423160 Brake actuators GIRLING Ltd 18 Dec 1973 [19 Dec 1972 5 Jan 1973 4 Sept 1973] 58647/72 853/73 and 41451/73 Heading F2F In a wheel brake actuator comprising a first piston assembly 5 for service braking and a second piston 2 urged by a spring 3 to apply the brakes for parking or in emergency and released by fluid pressure, force transferring means 13 extending axially and outwardly and release means 12 the parts 12, 13 extend through piston 2 with clearance, part 13 being engageable with piston 2 upon release of the opposing fluid pressure. A bush 14 is screw-threadedly connected at or near the outer end of part 13 and is a loosefit within an outer bush 15 screwthreadedly attached to piston 2, the bushes having complementary shoulders which are normally spaced apart and permit relative movement of the bushes in one axial direction but prevent it in the reverse sense. In the event of pressure failure the brake can be released manually by unscrewing member 13 from the bush 14 which is frictionally held against rotation by bush 15, member 13 being thus moved axially to release the brake. In a modification the force transferring member carries a part having diametrically opposed slots and a bush carries pins or pegs, release of the brake being achieved by aligning pins and slots to allow longitudinal movement. In another modification Fig. 5, a push rod 25 has a counterbore 26 within which is located a release plunger 27 with a wedge portion 28 and balls 29 are retained in circumferentially spaced apertures in the wall of the counterbore, to engage the part 28, by a cylindrical member 31 held in position by an end cap 32. The brake is released in the event of fluid pressure failure by pressing plunger 27 against a spring 33 to allow the balls to move inwardly and allow movement of the rod 25.

Title: Improvements in or relating to electromagnetic devices suitable for phonograph and the like recording and reproducing
IPC: H04R11/08
Filed: 1926-01-12
Abstract: 246,143. Marconi's Wireless Telegraph Co., Ltd., (Goldsmith, A. N.). Jan. 12, 1926. Magnetic instruments; systems for transmitting music; diaphragms. - An electromagnetic recorder and reproducer is constructed with electromagnets arranged on both sides of an armature constructed as a peripherally-clamped circular diaphragm which may be stretched and is connected to the stylus bar. Fig. 8 shows the circuit arrangement, the magnet windings 5, 6 being in series in a circuit including the coil 7 of a transformer 8, which impresses the current on a valve amplifier 13 whose output circuit delivers through transformer 15 to further amplifiers or direct to a loud speaker. The mid-point of the coil 7 is connected to a point in the magnet circuit between the magnet windings. In one construction, Fig. 1, an insulating casing in two parts 31, 32 connected by a screwed sleeve 35 clamps a diaphragm armature 38, to which the stylus bar 40 is connected. Each part 31, 32 carries a magnet composed of two rings 43, 45 and two angle pieces 61 to receive the coils, the ends of which are connected to terminals 53. Screws through the casings and engaging the inner ring secure the rings and angle piece together and in position. In a modification, Fig. 5, the casing is constructed to stretch a thin steel diaphragm aramature 114, which carries a disc 134 for connection to the stylus bar 133. In this construction, the two parts 103, 116 of the casing are flanged and fitted with adjustable shouldered linings 104, 117 to support discs 107, 120 carrying the magnets. After fitting up the elements to the part 103 the diaphragm 114 is clamped between roughened faces on the flange 130 and a ring 112, and the part 116 is then applied, whereby a projection 132 thereon stretches the diaphragm as the flanges are drawn together by screws 135. The elements of the part 116 are then fitted up and adjusted.

Title: Improvements in or relating to electric heating apparatus
IPC: H05B1/02
Filed: 1954-01-13
Abstract: 746,796. Automatic temperature control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 13, 1954 (Jan. 21, 1953], No. 968/54. Class 38 (4). The temperature of a cooking utensil 41 on a surface heating unit 20 of an electric cooker is detected by a temperature-variable resistance 42 biased into thermal contact with the bottom of the utensil. Resistance 42 which has a negative temperature coefficient forms part of a resistance network, terminals I, II of which are supplied from A.C. mains L1, N. The resistance network balances and produces zero voltage output at terminals III, IV, when the desired temperature is reached, to de-energize a relay 32 through thermionic valves 52, 51, 34 and thereby disconnect heating unit 20 from A.C. mains L1, L2.- Relay 32 operates intermittently thereafter to maintain the desired temperature, The desired temperature is set by a control knob 21 which, when moved from the " off " position, operates a cam 37 to close a switch 36 energizing the control system. Knob 21, which selects the desired temperature by adjustment of a potentiometer R6, has three ranges of movement. The first or " warm " range covers temperatures from 100‹ F. to 204‹ F. The second or " boiling " range is used when the cooking utensil contains water or food containing water. Within this range the knob also causes a cam 61 to position a contact 58 so that a continuously oscillated contact 59 periodically introduces a resistance R1 into the network in a sense tending to increase temperature. The time for which resistance R1 is introduced and hence the rate of boiling is dependent on the position of knob 21 in the boiling range, the temperature being constant by virtue of the boiling. The third or " fry " range covers temperatures from 235‹ to 450‹ F. Within this range contacts 58, 59 are permanently closed. The possibility of disconnecting resistance R1 in this range is referred to. In a modification the supply to terminals I and II is through a ballast resistance and contacts 58, 59 control a different resistance in the network. Design of the resistance network to reduce the effect of supply voltage variations and to reduce non- linearity of knob calibration is discussed.

Filed: 1990-01-06
Abstract: PURPOSE:To facilitate control of minute pressure difference by regulating the flow of gas to be circulated to the intake side of an anode discharge gas blower after being taken out from the discharge side, and thereby eliminating the pressure difference through control of the pressure of an anode. CONSTITUTION:The side of a cathode 1 subjected to larger gas flow is controlled so that the rotation number of a cathode circulation blower 32 may be controlled to have a required discharge flow to perform pressure control at the side of an anode 2 subjected to less gas flow for the purpose of eliminating pressure difference. As a result, immediate control with good responsiveness is possible even in the case of slight fluctuation in pressure. The gas flow to be discharged through an anode discharge gas blower 22 is set at or more than the level to be fed to the anode whereby the inside of system on the exit side of the anode. The flow of anode discharge gas is controlled by circulating the discharge flow of the blower partially by means of a pressure difference control valve 35, and thus the control of pressure difference is made easy. It is thus possible to eliminate the pressure difference between the poles of the cathode and anode with the anode system with a good responsiveness.
