Title: Capacitive transducers
IPC: H04R19/00
Filed: 1970-08-04
Abstract: 1313551 Capacitor transducers MARCONI CO Ltd 4 Aug 1970 [5 Aug 1969] 37450/70 Heading H4J In a capacitor transducer at least one capacitor plate (e.g. the back plate) comprises a bundle of sections of a metal susceptible to anodic oxidation. The sections may be aluminium or tantalum wire. Each section may be cropped at an end at an angle to provide an asperity (upstanding area) on a major surface of the back plate. Alternatively, asperities may be provided by a controlled etching process. The major surface is then provided with a layer of oxide formed by anodic oxidation. The oxide layer may be an electret. The main body of the wires may be of commercial grade material, a thin layer of the same material in a very pure state being provided on the ends of the wires to be oxidized. The very pure material may be provided by evaporation. In one form of manufacture, wire lengths equivalent to many plates are laid up and then sliced to provide back plate blanks. The selection of the wire gauge determines the total hole area providing communication through the back plate to an acoustic chamber. Where blind holes are required, a lacquer or wax layer or a film of synthetic material seals the rear surface, the wire bundle is held in position by a compression band or by cementing of the outer layer. Evaporation coating and anodic oxidation also assist in holding the assembly together. In a noise cancelling arrangement a diaphragm moves differentially between fixed front and back plates both as described above.

Title: Improvements in or relating to automatic railway vehicle couplings
IPC: B61G5/04
Filed: 1929-12-06
Abstract: 337,257. K³rt÷ssy, L. Dec. 6, 1928, [Convention date]. Couplings, non - automatic, convertible to automatic ; combined buffer and draw-gear. - In order to permit coupling during a transition period, of a neavy and final coupler-head of the central buffer type with a lighter transition head that is temporarily supported in front of the draw-hook without the latter head being liable to damage, the heavy coupler-head 1 is pivotably mounted on a supporting-bar 27 which is resiliently mounted on the vehicle, so that the connection yields to compressive forces and is capable of transmitting tensile forces only, the connection being subsequently rendered rigid for normal use of the coupler-head. In fhe construction shown the coupler-head 1 is connected with the bar 27 by means of two joints 30, 33 and an intermediate link 29, while the rear end 66 of the bar 27 is threaded and engaged by a nut 67 so that it can be adjustably positioned in relation to a main draw-bar 64. A spring 65 is disposed between a stop 75 on the draw-bar 64 and a collar 76 on the supporting-bar 27, the entire connection allowing the coupler-head to move rearwardly and in any direction laterally under compressive forces, the lateral movement being limited by stops 68. At the end of the transition period stiffening members are inserted between the coupler-head 1 and draw-bar 64 so as to render the connection between these two parts rigid. At its forward end the coupler-head is supported by means of springs 69 surrounding rods 70 depending from brackets 72, the rods having upper terminal collars 71 with broad under surfaces whereby the coupler-head is subject to a gravity centralizing effect. During the transition period a chain 73 suspended from the head 1 is used to couple with the draw-hook on an opposing vehicle, tightening of the chain being effected by adjustment of the screw-and-nut 66, 67. In modifications, however, an independent tightening is obtained by attaching the chain 73 to an eye 79 on a rod which is adjusted either by a screw-and-nut 80, 81 as shown in Fig. 2 or by a right and left hand threaded rod.

Title: High-pressure fluid flow pressure controller
IPC: G05D16/10
Filed: 1966-08-22
Abstract: 1,129,716. Fluid-pressure servomotor systems. FISHER-GOVERNOR CO. Aug. 22, 1966 [May 20, 1966], No.37616/66. Heading G3P. A fluid-pressure regulator comprises a main valve member 28 co-operating with a seat 31 to control the flow from an inlet 17 to an outlet 18, the valve being adjusted by an actuator diaphragm 36 which is subjected to downstream pressure in a chamber 48, spring loading 46 and a pilot controlled pressure in a chamber 50. The pilot controlled pressure is determined by a two stage pilot assembly which comprises a first differential pressure regulator valve 85 which controls the flow of inlet fluid through passage 94 to passage 106 in accordance with downstream pressure acting on piston 85a fed through passages 54 and 89 and the reduced pressure in passage 106 acting on the piston, thus the pressure in passage 106 fed to the second stage is at a constant pressure differential above the downstream pressure. The second stage pilot comprises a diaphragm 118 subjected to downstream pressure in chamber 123 and controlling supply and exhaust valves 110, 132. The diaphragm moves against a spring loading 150 to produce a pilot pressure in chamber 116 which is connected to the chamber 50 of the actuator. The actuator 36 is thus adjusted in response to changes in inlet and downstream pressure. The actuator 36 also moves a position indicator rod 70.

Abstract: 1405616 Catalytic oxidation of S02 to SO3 PECHINEY UGINE KUHLMANN 11 Aug 1972 [13 Aug 1971] 37638/72 Heading C1A A multi stage process for the catalytic oxidation of SO 2  to SO 3  is one in which oxidation product from a catalytic oxidation stage is passed through an absorber, e.g. containing H 2 SO 4 , to remove SO 3  and is thereafter passed to a further catalytic oxidation stage via a heat exchanger which raises the temperature of the gas prior to its introduction into the further oxidation stage, and a hot dry gas which does not interfere with the subsequent oxidation reaction being injected into the gas leaving the absorber so as to vaporize H 2 SO 4  mist which has already formed and to prevent the formation of H 2 SO 4  mist at least up to the inlet of the heat exchanger. This helps to prevent corrosion of the heat exchanger.

[Class 138 (ii).] In order that the actuation of the controls of a fluid-pressure actuated laundry press in the press-closing direction may simultaneously and automatically operate the controls of another fluid-pressure actuated press in the press-opening direction, a normally, closed ball valve 5, Fig. 2, in a fluid-pressure supply pipe 6 is arranged beneath the operating lever 1 of the fluidpressure supply valve to the cylinder 2, Fig. 1, operating the press, and a piston and cylinder 9, 10, Fig. 3, are arranged beneath the operating lever 3 of the exhaust valve of the cylinder 2. The valve 5 of one press and the cylinder 9 of the other are connected by pipes 8 as shown in Fig. 1. Upon the full depression of the levers 1, 3 of the press A to close this press, the opening of the valve 5 of this press admits pressure to the cylinder 9 of the other press B whereby the piston-rod 11 raises the lever 3 and opens the exhaust valve of the press B, and so opens this press. To provide for independent press operation the levers 1, 3 may be depressed by depression of buttons 14, 15 associated therewith, the depression of the levers 1, 3 being sufficient to operate the inlet and exhaust valves of the cylinder 2 but insufficient to strike the operating stem 7 of the valves 5. The controls of more than two presses may be connected similarly.

Title: Improvements in or relating to slag-forming masses and electrodes for use with electric arc welding
IPC: B23K35/365
Filed: 1956-12-12
Abstract: A slag-forming mass for use in the electric-arc welding of iron and iron alloys is made by mixing slag-forming constituents with a binder and drying the paste obtained, use being made as binder of a colloidal gel of a fluoride of Mg, Ca, and/or Sr which has been produced by causing metal ions to act upon and coagulate a suspension of a finely-divided fluoride of Mg, Ca, and/or Sr, these metal ions being capable of replacing Ca, Mg, or Sr ions in the crystal lattice of the fluorides.  Metal ions which may be used include Ca, Mg, and Sr ions themselves as well as Cd, Zn and cupric ions: they may be introduced as the chloride, bromide or nitrate.  In the examples, the binder is made by (1) treating a suspensiong of MgF2 with MgCl2, (2) treating a suspension of fluorspar with CaCl2, and (3) adding CaCl2, or MgCl2, or chalk+HCl, to chalk in HF.  The examples also refer to slag-forming masses variously contained rutile, FeMn, FeCr, FeSi, FeTi, CaCO3, felspar, quartz, Mn3O4, and iron powder.  These masses may be used as granules for submerged-arc welding or as coating for welding electrodes composed of e.g. 18/8 steel or mild steel.

Title: Improved method of spraying surfaces with paint, for use in sign writing and the like
IPC: B05D1/32
Filed: 1929-12-11
Abstract: 333,851. Grinyer, E. S., and Hart, S. Dec. 11, 1929. Drawings to Specification. Ornamenting. - Signs, decorations, or designs are produced by spraying with paint or like medium, part of the surface being protected during the spraying operation by a 1ayer of a substance, such as grease or a substance known as Glass Cote, which is applied by means of a hand brush and can subsequently be removed, as by the use of hot water or other solvent. In one example, the letter A is blocked out with grease &c., the whole surface is sprayed with ce11u1ose paint, and the grease is removed, a recessed letter in the colour of the original surface against a background of the colour applied being thus produced. A1ternative1y, the letter may be produced in re1ief by protecting the background instead of the letter. A blue letter with black shading recessed in a red background is produced by applying blue paint to the surface, b1ocking out the letter, applying black paint, extending the blocked-out area so as to cover the shading. applying red paint, and finally removing the protective coatings. In another example, a protective coating is applied to a painted surface over an area sufficient to include the 1etter which is left exposed, paint is applied within the area, and the protective coating is removed. A shaded 1etter may be produced as before by extending the coating and applying a second colour.
