Title: Improvements in and connected with Electric Signalling Systems.
Inventor: LAMBOURNE RICHARD
IPC: B66B19/06
Filed: 1916-09-27
Abstract: 109,325. Lambourne, R. Sept. 27, 1916. Mine signalling systems.-In an electric signalling system, particularly for mines, the signals are cancelled by contacts operated, when the winding-engine starts, through a slipping clutch. The invention may be applied to systems in which a cancelling relay circuit is closed, or in which connexion between battery and signal line is broken, in order to cancel signals, and in the latter case arrangement may be made immediately to restore the line connexion so that signals may be given during running of the engine. In the preferred form, a metallic pendulum 1, mounted on a spindle 2 and having a disk 8 and adjustable bob 5, is swung in one direction or the other by a disk 6 rotated when the winding-engine is running. Frictional contact of the disks 6, 8 is maintained by a spring 7, and movement of the pendulum is limited by stops 4. When the pendulum moves, its upper end makes momentary contact with a metal plate 12 yieldingly supported on pins 13 insulated from the frame of the apparatus by a fibre supporting block 10. Wires 15, 16 in the relay circuit are connected respectively' to the frame of the apparatus and the plate 12, so that the cancelling relay circuit is closed when the pendulum 1 and plate 12 are in contact. The pendulum may be adjusted so as to remain dcflected during the running of the engine, or to give an initial kick and slin back to its normal position when the engine attains a steady speed. In the latter case, signals given during the running of the engine are not cancelled as the engine stops. In an alternative arrangement, the pins 13 are in series in the connexion between battery and signalling-line, circuit being completed through a modified form nf the plate 12 when it rests on supporting-heads on the pins 13. but broken when the plate is raised by the pendulum. Connexion is restored by the pendulum slipping back to normal position, or remaining deflected and closing an alternative circuit between the pins 13. In a modified form of pendulum clutch, the disk 8 is replaced by a divided spring- compressed ring embracing the periphery of a disk carried by the disk 6. According to Provisional Specification 13746/16, the pendulum is carried on the engine shaft, or on a shaft driven by the engine, by two semi-circular straps embracing the shaft, endlong movement being prevented by collars on the shaft, and the upper end of the pendulum carries an insulated plate contact normally co-operating with a pointed contact above it and breaking circuit when the pendulum moves. According to the Provisional Specification 1233/17, the upper end of the pendulum rod raises a contact plate, breaking circuit with contacts below it and instantly making contact with contacts above it.

Filed: 1941-10-28
Abstract: 552,685. Calcium chromate. LE BROCQ, L. F., and COLE, H. G. Oct. 28, 1941, No. 13846. [Class 1 (iii)] Calcium chromate adapted for use for anticorrosion purposes is obtained by a process in which a solution of a freely soluble but unstable form of calcium chromate is produced by adding to a chromic acid solution an insufficient quantity of calcium hydroxide for complete reaction, cooling below 20‹C., and preferably below 5‹C., and adding further calcium hydroxide while keeping the temperature below the stated values. The solution is adjusted to pH 9 by addition of further calcium hydroxide filtered and allowed to stand at about 20‹C. when a moderately soluble stable form of calcium chromate separates out; this may be rendered less soluble by heating the dried precipitate.

Abstract: 751,477. Welding by fusion; making pressure vessels. BABCOCK & WILCOX, Ltd. May 18, 1954 [May 18, 1953], No. 13861/53. Addition to 713,054. Classes 83 (2) and 83 (4). In a modification of the pressure vessel claimed in the parent Specification 713,054, the said metal around the tube seat, the hardness of which is unaffected by heating and cooling consequent on a fusion welding operation and the dimensions of which are such that a seal weld may be formed between a tube in the tube seat and the vessel without heating the latter above its lower critical temperature, is provided instead by a deposit on the outside surface of the vessel or by a lamina on either the inside or the outside surface of the vessel. A mild steel or commercially pure iron washer 5, Fig. 2, is welded at 7 to the inner surface of a wall 1 of a high tensile steel drum around a tube seat 3 drilled in the wall and provided with annular grooves 4. The drum and washer may be preheated. After the welding the drum is stress relieved and the tube 2 is expanded in the seat 3, a seal weld 8 being then made between the tube 2 and washer 5. The welds 7 and 8 may be of the same ductile metal. The washer may be welded wholly or partly in a groove and may be applied to the outer surface of the drum. The seal weld made between the washer 65, Fig. 9, and a thick-walled alloy steel tube 62 is made between the washer and a mild steel or pure iron deposit 71 in the tube end to ensure that the tube is not raised above its lower critical temperature during seal welding. The tube is stress relieved after the deposit 71 is made thereon. In a further embodiment an annular groove 31, Fig. 6, having an inner diameter smaller than the tube seat diameter 'and a diameter on the outer surface of the drum larger than that at the bottom of the groove, is made in the wall 21 of a high tensile steel drum and is filled with a mild steel or pure iron deposit 32. The drum is then stress relieved and the tube seat 23 with annular grooves 24 is formed in the wall. The tube 22 is expanded in the seat and a seal weld 28 is made. The groove 31 may be formed, filled and the drum stress relieved after the seat has been made. The groove may be omitted and the deposit 32 made directly on the outer surface of the wall. A weld deposit may be applied over the wall of the vessel where a number of tube seats are to be formed; alternatively a lamina may extend around two or more seats and may be formed of two or more sheets welded to the vessel wall as described in Specification 519,526.

Title: Improvements in cut-off valves
IPC: F16K17/32
Filed: 1943-08-27
Abstract: 594,066. Fluid-actuated valves. WATERMAN, W. Aug. 27, 1943, No. 14026. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 1, . 1944.] [Class 135] A valve which is moved to the closed position by fluid flowing through the valve casing is normally kept in the open position by a holding means releasable by a predetermined fluid force acting on the valve member, the latter being also provided-with means operated by a reverse flow of fluid to guide it into re-engagement with the holding means. In the form shown in Figs. 2 and 3, the valve 10 mounted on a stem 17 is held away from its seat 11 during normal flow by a locking means comprising flanges 23 engaging the ends of splines 21 on the stem. Abnormal flow acting on vanes 13 turns the valve against the resistance of a flat torsion spring .15 so that the flanges 23 register with the spaces between the splines 21 and the valve is then moved by the flow into the closed position, a non-rotatable block 18 on the torsion spring sliding in a slot in the stem. Reverse flow will cause the flanges 23 to slide up the spaces between the splines and, at the end of the travel of the valve, spring 15 will rotate it into the position where the flanges 23 are engaged against the tops of the splines. In order to prevent operation by a surge, the valve is prevented from turning on its stem for a predetermined time, such turning being permitted only when a projection 54 on the valve can slip past a projection 55 non-rotatably mounted on an anchor 35. To effect the required delay, the valve stem is slidably mounted in the anchor and its rate of forward movement is controlled by a dashpot 57, the latter comprising a cylinder 38 formed by the anchor and a piston 40, carried by the stem. Fluid escapes from the dashpot between the cylinder and piston and also around the stem, and when the piston is returned to normal position by a light spring 47, fluid can enter the cylinder through an aperture 50 past a check valve 52. Specification 591,805 is referred to. The Specification as open to inspection under Sect. 91 comprises also valves closing after a predetermined volume of flow. In one form, Fig. 5 (Cancelled), the valve 65 carries actuating vanes 100 and a dashpot 69, similar to that shown in Figs. 2 and 3, but provided with a passage 67 which, when it slides clear of the dashpot cylinder, eliminates the action of the dashpot and allows the valve to close quickly. The valve can be made to respond to different volumes by means of an adjustable collar which varies the area of the passages past the vanes 100. In a modification, Fig. 6 (Cancelled), the dashpot cylinder is constituted by a bellows 85 of which the natural resiliency acts as a restoring spring to the valve. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 107,434, [Class 135].

Abstract: 568,821. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 30, 1943, No. 14104. Convention date, Aug. 29, 1942. [Classes 39 (i) and 40 (v)] An arrangement for comparing two voltages comprises a cathode 2 and a fluorescent anode 1 with two deflecting electrodes 3 and 4, to each of which one of the two voltages is applied. The resulting pattern produced on the fluorescent anode indicates the relative strengths of these voltages. The voltages may be applied to the electrodes through rectifying diodes 20 and 21 and amplifiers 25 and 26. The electrodes 3 and 4 may be side by side, in which case a shadow is produced on the anode when voltages are applied to the electrodes and a bright line in the shadow area indicates by its position the difference between the voltages of the electrodes. If these are placed end to end, the application of voltages produces a shadow which is stepped at the edges unless the voltages are equal. In either case the state of the shadow will indicate when both electrodes have no voltage. Specification 545,577 is referred to.
