Title: Improvements in and relating to electric welding machines
IPC: A01F11/08
Filed: 1936-04-30
Abstract: 474,247. Electric welding. BRITISH THOMSON-HOUSTON CO., Ltd. April 30, 1936, No. 12326. Convention date, April 30, 1935. [Class 83 (iv)] In an electric welding- machine in which the electrodes are operated by air or liquid pressure, the pressure cylinder is provided with two double acting pis tons, one of which moves' the electrodes directly or through a rod, and the other is a counter piston with variable stroke. The length of the operative stroke of the electrodes mav thus be varied tc suit the insertion of articles of different sizes, and the no load time of the machine is thus reduced to a minimum. The movable electrode 4 of a roller seam welding machine may be connected by a lever 18 and rod 17 to the rod 14 of the working piston 2 which moves in the cylinder 1 together with the counter piston 3. The piston rod 14 is of larger diameter than the piston rod 15, the latter being provided with an adjustable stop 5. The operation is controlled by valves in a chamber 9 controlled by a pair of pedals 16. When one pedal is operated fluid passes through a reducing valve into the chamber 7 and moves the electrode 4 into contact with the work 13 without pressure. Further operation of this pedal disconnects the reducing valve and full welding pressure is applied to the piston 2, the welding current being simultaneously switched on. On moving back this pedal to its intermediate position, the electrode is returned by then pressing the other pedal, fluid being thus supplied to the chambers 6 and 8, and due to the different diameters of the piston rods the piston 3 moves upward as far as the stop 5 allows it, the projection 11 on the piston 2 engaging the piston 3. If the electrode is required to make a full return stroke the second pedal is operated so that the chamber 8 is connected to the atmosphere. In a modification the piston rods may be of the same diameter in which case the chamber 6 is connected to the chamber 9 through a reducing valve. The Specification as open to inspection under Sect. 91 states that the machine may be used for spot welding. This subject-matter does not appear in the Specification as accepted.

Abstract: 559,997. Locking lift gates etc.; mechanical switches without quick action. FURSE & CO., Ltd., W. J., and BROWN, F. Sept. 2, 1942, No. 12358. [Class 78 (iii)] [Also in Group XXXVII] Relates to a lock switch for use where an electrical circuit is controlled by closing or opening a door or the like, particularly a lift gate or door, and of the type incorporating electrical contacts 15 adapted to be operated by the entry and withdrawal of a pawl or tongue 12, the lock switch and pawl being mounted respectively on the two relatively movable parts to be locked together, e.g. a lift gate and the jamb. According to the invention, the pawl 12, or an associated part, is adapted, on entering the lock switch, to engage an inclined track 18 on a rotary switching member 16 and thus rotate the member to connect the contacts, so that, in the case of a lift, the lift motor can only be started when the gates are shut. As shown, the lock switch comprises a casing 10 attached to the jamb and having a slot 11 for entry of the pawl 12, carried by a lift gate or door, while the member 16 is a metal drum carrying an insulated metal bridging bar 17 which closes the contacts 15 when the Z-shaped track 18 on the drum is engaged by a projection 14b on the pawl, to rotate the drum against the action of a spring 19. On rotation of the drum, the opening 11 is obstructed by a guard plate 21 engaging behind the vertical part 14 of the pawl, the guard plate being moved by a peg 22 on the drum engaging a hole 23 in the plate which is pivoted at 24 to the casing 10 and determines the inoperative position of the drum. The lock also incorporates the usual locking lever 26 mounted on a spindle 27 provided with a lever 28 which is rocked by a ramp as the lift moves, the lever 26 being spring-biassed to hook over the horizontal part 13 of the pawl. In addition, to prevent the pawl from being operated without the exertion of some effort when the lever 28 is disengaged, a spring-loaded plunger 30 or the like is provided which is raised by an inclined part 14a on the pawl when the latter enters the casing 10 and drops into a recess 14c on the part 14.

May 8, 1947, No. 12495. [Classes 38 (ii) and 38 (iv)] [Also in Group XXXIX] To prevent demagnetization of the permanent magnet 20 by the control winding 22 in a saturable reactor or transformer of the kind in which a core 16, 17 carrying the controlled windings, such as 2, 3, is magnetically biassed by the opposed magneto motive forces of the magnet and control winding, the magnet and the portion 18 of the core carrying the control winding form parallel branches of the magnetic circuit which are isolated from one another by one or more air gaps, such as 19, 21. By this arrangement, whilst the magnet and control winching produce opposing fluxes in the portions of the core carrying the controlled windings, any flux reaching the magnet from the control winding over the air gaps 19, 21, is not opposed to that due to the M.M.F. of the magnet itself. In the arrangement shown, the controlled windings 2, 3 are in series with the primary winding of a transformer 7 supplying a load 15 through a rectifier 12, the control winding 22 being energized in proportion to the load voltage so as to modify in a corrective sense the reactance of the controlled windings upon deviation of the load voltage from normal.

Abstract: 568,082. Preventing freezing of moisture in gases. RODWAY, J., and CLAYTON DEWANDRE CO., Ltd. Aug. 11, 1943, No. 13008. [Class 55 (ii)] In a means for preventing the freezing of moisture present in the air or gas of a pressure system the gas is passed through a passage from which a proportion passes into a chamber wherein it is mixed with a quantity of the vapour of a liquid of low freezing point and then returned to the main gas or air stream, the passage being so formed that a higher vapour concentration is obtained at low gas flow than at normal flow. As shown gas enters a passage 2 through a tapered portion 7 in which is a port 5 leading to a chamber 3 containing methanol. The gas with a proportion of methanol vapour leaves the chamber 3 through the port 6 and rejoins the main gas stream at the tapered portion 8 which is connected to the suction side of a compressor. The tapered portions and ports are so proportioned that the quantity of gas passing through the chamber depends on the speed of gas flow through the apparatus.
