Title: Improvements in and relating to electric arc welding and like operations and to electrodes therefor
IPC: B23K9/067
Filed: 1919-06-30
Abstract: 156,476. Holslag, C. J. June 30, 1919. Heating by electricity.-Separate adjacent arcs are formed simultaneously between a number of electrodes and the work with current of different phases. Three electrodes may be connected with a three-phase delta or star-system. The middle point of the star may be connected with the work. In the three-phase star-arrangement shown in Fig. 2, one electrode b is arranged in advance of the other two a, e so that three separate arcs A, B, E are produced with a conical or like depression D in the work C. Six electrodes may be used with a three-phase four-wire system, the middle point of the star being connected with three electrodes, and the free ends of the star with the other electrodes. A multiple electrode may be formed by embedding a number of metal elements in the same or different planes in insulating material, as described in Specification 156,280. Four electrodes may be used with a two-phase four-wire system, two electrodes being connected in each phase. In a two-phase threewire system, one electrode b, Fig. 5, is made of larger section than the other two a, e. Specifications 25903/96 and 2413/15 also are referred to.

Abstract: 1,172,773. Moulds. GENERAL ELECTRIC CO. 24 July, 1967 [27 Oct., 1966], No. 33848/67. Heading B3F. In the investment casting of thin-walled castings in ceramic shell moulds 22 that are preheated in a metal container 12 packed with a ceramic granular material 26, distortion of the shell mould 22 by differential contraction forces 19 set up when the container and mould are taken out of a preheat furnace is prevented by providing a " cushion" " on the external lateral wall surfaces of the mould 22. The cushion may be provided by a layer 21 of woven and/or fibrous material, e.g. glass cloth, asbestos, glass wool, that can deflect and absorb the forces 19 and pads (21a), (Fig. 5, not shown) of a similar material may be placed between the layer 21 and the external walls of the mould. Alternatively a single coating of a flock-type material and binder may be sprayed on to the mould walls (Fig. 6, not Shown). The ceramic granular material 26 may include vermiculite and aluminium silicate (mullite) and the mould 22 may be produced by the " lost wax " process using a siliceous material.

A pneumatic transducer comprises a flapper 21, rotated in response to an input torque or force to control the flow of air from nozzles 27, 28 to provide a pressure differential in the lines 33, 34. The nozzles are supplied with air from a common source through equal restrictions 25, 26. The pressure differential in lines 33, 34 on movement of the flapper from the null position acts on a piston 44 to adjust a needle valve 48 controlling the flow from an inlet 55 to a transducer output line 60. The output pressure is fed through line 61 to act on a piston 64 to provide a negative feedback to the flapper and also through a line 62 to a piston 73 which acts through a dashpot on a piston 75 to provide a positive feedback and integral control. The dashpot also acts as a damper on movements of the flapper. The pistons 44, 64, 73, 75 are suspended by diaphragms to prevent friction. The point of application of the feedback pistons on the flapper may be adjusted.

A mixer valve or transistor 9, for a multiband radio or T.V. receiver, is connected to operate as a self-oscillating mixer in one waveband and is switched to operate as an additive mixer in another waveband. As shown, in the V.H.F. position of switch 13, V.H.F. signals are fed via the V.H.F. radio frequency amplifier 32 to the emitter of transistor 9 together with signals from the V.H.F. oscillator 16 so that additive mixing occurs to produce an I.F. output at 15. In the U.H.F. position of switch 13, an oscillator feedback loop 10 is coupled to the emitter by lead 12 so that transistor 9 acts as a self-oscillating mixer. U.H.F. signals are received via an input filter 25 and a U.H.F. radiofrequency amplifier 26.

Abstract: 369,556. Treating cereals. THOMAS, D. I., Brynffrwd, Penygraig, Glamorgan. Nov. 20, 1930, No. 34982. [Class 58.] Cereals are treated to destroy insect ova or larvae and to sterilize the product by preliminary rolling or crushing followed by a further rolling operation, the flakes obtained being heated while under continuous movement to effect sterilization. The cereal after preliminary cleansing is fed through a shoot 2 to preliminary crushing rollers 1 from which it is removed by a scraper 4 and fed flat-wise by a shaking table 5 and a plate 10 to crushing rollers 3 and may be subjected by further rollers to a third crushing operation. The rolling is sufficiently fine to disintegrate the ova present. Any or all of the crushings may be followed by screening to remove ova. A scraper 11 removes the product from the final rollers, which may be heated to about 100‹ C., and a hopper 12 delivers it to a heat-insulated sterilizing oven 14 having tables 15 over which the product is carried by a conveyer consisting of a pair of endless chains having transverse conveyer bars 19. The bars 19 have slots 20 to accommodate the sides 16 of the tables and serrations 21 which are staggered on successive bars and produce a corrugated surface on the mass, thus increasing the surface subjected to the radiant heat from electric heaters 23. Heating pipes through which steam or hot oil is circulated may also be used. To give a positive feed, at intervals a bar 19 with a plain lower edge moving in contact with the table is provided. Hot dry air or inert gas may be injected into the oven to create slight pressure therein. The product issues through hopper 18 at a temperature of at least 100‹ C. Vapours may be withdrawn from the oven 14 by pipes 25 leading to an exhaust fan 27. Alternatively hot and dry air or inert gas may be injected to create slight pressure within.the oven.
