Filed: 1926-10-22
Abstract: 260,583. Colas, J. E., (Assignee of Bertault, G. M.). Oct. 29, 1925, [Convention date]. Mercury switches; retractive switches; dashpots.-The casing 4 contains a damping device comprising a cylinder 10 and piston 9 which is connected to a shaft 5 pivoted in the walls of the casing and is moved quickly upwards by the depression of a. flexible pedal 6 on the passage of a railway vehicle. This movement creates a vacuum in the cylinder so that oil from the casing lifts a valve 12 against the action of a spring 13 and fills a chamber 10<a>, so retarding the free descent of the piston when the wheel of the vehicle has passed. A calibrated orifice 11 in the piston allows the oil to leak away slowly, but the shocks due to the passage of succeeding wheels are greatly reduced. The bearings of the shaft are lubricated by the splashed-up oil collecting in a groove 15, the oil being afterwards returned to the box. The switch, Fig. 4, consists of a support 18 on the shaft 5 supporting by means of shock-absorbing springs 19 a mercury container 17 having contacts 21 - - 24 connected by part flexible, part rigid leads 25 - - 28 to three terminals 29 placed one behind the other. These terminals are in turn connected by brackets 29a and wires 30 to terminals 31 whence lead conductors 32 passing through a metal tube 33 out of the casing 1. According to the position of the switch, either of the pairs 21, 22 or 23, 24 of contacts are connected together to control a signal by suitable relays or motors.

Title: Electric time switch
IPC: G04C1/06
Filed: 1937-09-30
Abstract: 485,521. Actuation of switches. ZBINDEN, E. Sept. 30, 1937, No. 26494. Convention date, Oct. 5, 1936. [Class 38 (v)] [Also in Group XVIII] A time switching device comprises an electric motor 8 coupled to a shaft 20 of a differential gear, one side of which drives through gears. 21, 22, a switch drum 24, and the other side of which drives a wheel 13 coupled to a disc 10 on an arbor 1 to which is connected one end of a clock spring, the other end of which is connected to a barrel 2 which drives a time switch 43, 44. The switch drum 24 is provided with a star wheel 25 which co-operates with a spring urged roller in such manner that the resistance to rotation of the drum 24 is greater than that of the rewinding mechanism when the clock spring is unwound. Thus, the clock spring is always rewound before a switching operation can take place. The disc 10 is provided with a pin 30 biassed to the right and engageable in a bevelled recess 39 in the disc to prevent reverse turning of the disc. A second pin 29, biassed to the left, is engageable positively with the disc 10 at its right-hand end, and at its left-hand end co-operates with a contact arm 34. A nut 4, threaded on the arbor 1 has slotted engagement with a pin 5 on the barrel 2 and is engageable with an arm 32 fixed to pin 29. As shown in the Figure, the clock spring is unwound and nut 4 has allowed pin 29 to move to the left thus unlocking disc 10 and closing contacts 34, 35 to energize motor 8. Owing to the greater resistance of drum 24, the motor turns the disc 10 to rewind the clock spring, causing the nut 4 to travel to the right and move pin 29 to break the motor circuit at 34, 35 and lock disc 10 against further rotation. When the clock spring unwinds, the nut 4 moves to the left and the rewinding is repeated. If now the motor circuit is closed by the time switch 43, 44, since disc 10 is locked, the drum 24 is rotated until the motor circuit is broken at contacts operated by the drum, which also operates contacts controlling external circuits.

Title: Improvements in or relating to the anode assemblies of x-ray tubes
IPC: H01J35/08
Filed: 1950-10-31
Abstract: 684,796. Making electric components; welding by pressure. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 31, 1950 [Nov. 12, 1949], No. 26502/50. Classes 83 (ii) and 83 (iv). An anode assembly for an X-ray tube is made by enclosing the target portion of an anode block in a metallic hood which makes contact at corresponding surfaces, pressing these surfaces together and passing an electric current between the parts while in a reducing atmosphere. In applying this process to the making of a small dental X-ray tube, a ring 11 of an alloy, e.g. nickel-iron, or a nickel-cobalt-iron having about the same coefficient of expansion as glass and known under the Registered Trade Mark " Kovar," and a rod 12 are gold-brazed to an anode block 13 of copper with a target 15 of tungsten, a glass flare 16 is joined to the ring 11 in known manner, the anode 13 and a hood 17 are cleaned with acid, electro-polished and then assembled between a button 23, Fig. 5, of molybdenum or other high-melting-point metal and a block 24 of carbon supported by an electrode 25. The other electrode 27 is watercooled and pressed down with a pressure of about 114 lbs. obtained by rods 26 and a lever 31. The assembly is enclosed in a bell 22 supplied with hydrogen &c. An alternating current of 425 to 475 amps. is passed for about 1¢ minutes. This assembly is finally sealed to the cathode-bulb assembly by the flare 16. If desired the open end of the hood may be grit blasted or gold-plated after electro-polishing. If either of the parts are not made of copper they are plated with this metal and this may be followed by gold plating or by baking in hydrogen. Specifications 271,853 and 335,876, [both in Class 83 (iv)], are referred to.

Abstract: 389,540. Machinery guards. BRITISH UNITED SHOE MACHINERY CO., Ltd. and JONES, C. T., Union Works, Belgrave Road, Leicester. Sept. 23, 1931, No. 26516. [Class 80 (iv).] In a machine for levelling the bottoms of shoes such as is described in Specification 22155/03, [Class 17, Boots &c.], in which a shoe bottom is subject to rolling-pressure between a last 2 and a form 3, a guard is provided comprising a pair of parallel rods 1 which swing outwardly as the last and form swing inwardly into engagement with the shoe. The rods 1, 1 are secured in a fork 5 pivoted on the last axle 30, the fork being connected by a link 7 to a bell crank 8 pivoted on the machine frame. A spring 14 urges a cam surface 11 on the bell crank against a roller 12 on the form carrier 13, which, in descending, causes the roller to rotate the bell crank and consequently the fork 5. Thus any part of theoperator in danger of being caught between the last and form is forcibly removed. The machine has two lasts and two forms, one pair engaging the work while the other pair is swung outwardly so that a shoe may be placed on the last. The inner rod 1a of the left-hand last is bent inwardly more than the other rods to enable the operator to remove a shoe from the right-hand last when the left-hand guard is swung outwardly. In order that the rods 1 shall first yield and then positively remove any part of the operator, the rod 7 is constructed in two parts 17, 18, Fig. 3, yieldingly connected by a spring 19. A collar 20 limits the amount of yielding and a pin 21 in the part 17 engaging a slot 22 ensures a positive connection when the rod is in tension. In a modification, Fig. 4, in which the machine is stopped when the rods 1 are obstructed in any way, the fork 5 is constructed in two parts 26, 27 hinged horizontally at 28, at which point the link 7 also is pivoted. The part 26 bears the rods 1 and is held by a spring 29 against a stop 30 on the part 27 which is pivoted on the axle 30. Ratchet teeth 31 on the part 26 engage teeth on a segment lever 33 loose on the axle 30 when the part 26 yields. This lever is linked to a rod 25 operating a clutch which disconnects the driving mechanism by mechanism described in Specification 22155/03.

Abstract: 796,090. Radiation gas analysers. PARSONS & CO., Ltd., C. A. Sept. 2, 1955 [Sept. 14, 1954], No. 26562/54. Drawings to Specification. Class 40 (3). The invention relates to infra-red gas analysers of known type in which infra-red rays are passed by way of a rotary shutter device through two gas-filled absorption tubes, the rays afterwards acting upon the contents of two chambers partitioned from one another by a thin metal diaphragm adjacent a fixed electrode, the capacity variation between the diaphragm and electrode being amplified electronically. In cases where a wide concentration range is required for a gas with strong infra-red absorption the length of the sample cell must be very small giving practical difficulties. Accordingly a sealed attenuator cell containing the gas under investigation is inserted in the optical path including the sample, the arrangement being that the radiations most intensely absorbed by the gas are wholly absorbed by the filter tube and do not reach the sample cell. Hence the analyser operates with less stronglyabsorbed radiation which permits the use of a longer sample cell.

Abstract: 278,737. Soc. Anon. Fonderia del Pignone. Oct. 8, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Mines, marine. - Relates to automaticallymoored mines, and consists mainly in arranging the paying out of the mooring cable to start when the mine sinks to a predetermined safe depth, and to stop if the mine rises too high, whereby the mine is kept oscillating submerged at a safe depth while the anchor gradually goes to the bottom. As shown in Figs. 2 and 3, a hydrostat n on the mine A controls a switch connected by an insulated wire a in the mooring cable b to an electromagnet d in the anchor B. When the mine sinks to a. predetermined depth, the hydrostat opens the switch and the electromagnet d allows a spring s to turn a valve e to connect a cylinder i to an exhaust allowing a spring to apply a brake to the drum r of the mooring cable. The mine then rises until at a given depth the hydrostat again closes the switch, reversing the previous action, and causing the release of the brake. In modifications, the hydrostat on the mine locks or unlocks the drum of an auxiliary cable, which mechanically controls (1) the application or release of the brake, or of a definite stop acting on a toothed wheel coupled to the drum by buffers, or (2) the coupling or uncoupling of the mooring cable drum to or from an auxiliary drum paying out a plummet line in the reverse direction and acting as a brake to the mooring cable drum.
