Title: Improvements relating to the electric arc deposition of metal and to electric arc metal deposition apparatus
IPC: B23K9/00
Filed: 1955-02-10
Abstract: 787,910. Welding by fusion. BABCOCK & WILCOX, Ltd. Feb. 10, 1955 [Feb. 11, 1954], No. 4004/55. Class 83 (4). In arc welding or cladding with a consumable electrode, the diameter and rate of feed of the electrode, the current and its point of connection to the electrode are such that substantially all the heat necessary to fuse the electrode is derived from resistance heating. The arc may be submerged in flux or shielded by an inert gas such as helium or argon. The electrodes may be carbon steel or alloy steel such as stainless steel or non-ferrous, and a plurality of electrodes connected in series or parallel may be used. The current is fed to the electrode at a distance of 4-5 inches from the arc. In order to maintain constant the voltage between the contact means 25, Fig. 3, and the work 20, the height of the contact means 25 is adjustable by a motor 40 controlled automatically in accordance with this voltage. In a modification, Fig. 6, the rate of feed of the electrode 15 is controlled by an electronic device responsive to a photo-electric cell or a thermocouple 60 to maintain the temperature of the electrode at a point near the arc at a constant value. In a further modification, Fig. 11, the electrode is passed into a nozzle 85 and the resistance heating is such that the electrode fuses within the nozzle and emerges into the arc 30 as a stream of molten metal. Specification 680,791 is referred to.

Title: Improvements in gas ovens
IPC: F24C15/08
Filed: 1924-02-16
Abstract: 236,969. Helps, G. Feb. 16, 1924. Ovens; casings; joints and connections. -Gas ovens are constructed of panels fitted into a skeleton frame comprising corner-pieces and angleirons held together by bolts running parallel to the walls. In the form shown, the corner-pieces b and angle-irons form two rigid frames a, a<1> at the front and back of the oven, which are spaced apart by loose angle-irons c and held together by four bolts d; the whole of the corner-pieces and angle-iron members may however be separate, in which case twelve bolts are necessary to hold the structure together. The panels may be formed of concrete slabs with hollow air-spaces, or with thickened edges providing a distance-piece for the attachment of enamelled or other plates; or they may be of metal sheets packed with slag wool or other material. In a modification, two opposed panels are formed with flanged edges so that they fit over the edges of the other four panels in the manner of box-lids; they are bolted together by bolts in a similar way to that employed in the construction illustrated, and are spaced apart by the remaining panels and by angle-iron members.

Abstract: 847,291. Making heat-exchangers. DE BOCK, M. Feb. 3, 1959 [Feb. 7, 1958], No. 4034/68. Class 83 (2). [Also in Group XIII] In a heat-exchanger comprising an assembly of cast iron tubes 1 provided at their ends with nesting flanges 2 and with tubular steel extensions 3 secured to the tubes, e.g. during the casting process, a suitably apertured steel plate 5 is passed over the steel extensions 3 and is welded thereto (as at 6) to form a fluidtight joint. To facilitate the cutting away by means of a blow torch of a section of the plate 5 should it become necessary to replace one of the tubes 1, the plate is spaced from the neighbouring tube flanges 2 by spacing washers 13 and by interposed gaskets 4 of braided asbestos which serve to protect the cast iron parts during welding. A second plate parallel to and spaced from the plate 5 may be similarly welded to the tube extensions 3 (Fig. 4, not shown).

Abstract: 807,265. Automatic speed control. BRITISH THOMSON-HOUSTON CO. Ltd. Feb. 10, 1956 [Feb. 14, 1955], No. 4332/55. Class 38 (4). In a system in which two D.C. motors 1, 2 are required to rotate with a constant or uniformly varying angular relation wherein one of the motors 2 is supplied from its source through a booster generator 6, and a selsyn 34 is coupled to each of the motors 1, 2, the selsyn 3 being fed with single-phase A.C. from source 5 and having its polyphase windings interconnected with those of the other selsyn so that only when the rotors are in a predetermined angular relationship there is no output from selsyn 4, the output, which is single phase, is used to control the excitation of the booster generator in a sense to effect a change in the speed of the motor supplied therethrough in a manner to restore the desired angular relationship. The error voltage after amplification in an electronic amplifier 7 is rectified in a phase-sensitive rectifier 8 and applied to an amplidyne 9 to provide excitation for the booster 6. The booster and the amplidyne are driven by a common motor 10 and the booster normally provides a predetermined proportion of the voltage applied to machine 2. The system may be applied to more than two motors and in this case one of the motors such as motor 1 constitutes a reference to which the angular positions of the remaining motors are related. Selsyn machines will be coupled to each motor and for each of the motors, other than that providing the reference, a booster will be provided which is controlled by the error voltage obtained from the selsyn coupled to that motor. The speed relation between motors may be 1: 1 or any other desired ratio and in the latter case a suitable coupling must be provided between motor and selsyn.

[Also in Group XXXIII] A combined shock-absorber and retraction jack is illustrated, comprising a cylinder 10 containing a piston 12 attached to the pistonrod 13. Pressure fluid supply pipes 20 and 21 are fitted, the former having a non-return valve 23, releasable hydraulically when pressure fluid is admitted to pipe 20, by a branch 24. Pipe 21 is provided with a non-return valve. Two passageways are provided in piston 12, with non-return valves, one leading from the outer end of the cylinder to the inner end, its non-return valve being spring-loaded so as not to open until sufficient pressure to effect retraction is reached. The other passageway leads from the inner end to the outer, and contains a restricting orifice. As a shock absorber, the jack is sealed by the non-return valves in pipes 20 and 21, and on compression, the piston-rod 13 enters the cylinder, compressing the liquid, which flows through piston 12 past the spring-loaded non-return valve. On release of compression, the liquid re-expands, and flows back through the restricted passageway. To retract the jack, pressure fluid is admitted to pipe 21, unlocking valve 23, and the jack retracts normally. For extension, pressure fluid is admitted to pipe 20, raising pressure in the cylinder to cause the piston-rod 13 to move outwards, liquid flowing through the piston 12 past the restricted orifice. Specification 743,856, [Group XXXIII], is referred to.
