Title: Improvements relating to tube or cable sheath welding
IPC: B23K13/04
Filed: 1958-06-02
Abstract: 854,062. Making electric cables; welding by pressure; skelping. MAGNETIC HEATING CORPORATION. June 2, 1958 [June 7, 1957], No. 17493/58. Classes 83 (2) and 83 (4). In welding together the edges of a gap in metal tubing wherein the tubing is advanced and pressure is applied to close the gap at the welding point, the gap edges being heated by applying current to the tubing by contacts which engage the tubing at points on or near the gap edges and the current being at a frequency of at least 100 kc./sec. and such that the lowest impedance path follows the gap edges to the welding point, a core within the tubing is moved to present different surface portions successively to the heat liberated in the gap edges and welding point to prevent overheating of any one surface portion of the core. In one embodiment the tubing 10, Fig. 1, of copper, aluminium or alloys thereof contains a multi-strand steel cable 12, smaller than the tubing and the whole or each strand of which may be insulated, and the assembly is advanced, the edges 15, 16 of the gap 11 are urged together by rollers 13, 14 and electrodes 17, 18, which may be fluid-cooled as described in Specifications 748,528, 772,279 and 811,251, supplied with current of a frequency of the order of preferably 300-500 kc./sec. engage the tubing. The cable forms a magnetic core impeder to increase the impedance of the circumferential current paths in the tubing. Subsequent to the welding the sheath may be swaged to closely embrace the core. In another embodiment instead of a cable, a magnetic impeder 24, Fig. 3, e.g. of compacted and sintered magnetic oxide and insulation material, is arranged within the tubing and is carried by a piston-rod 28 of a piston 27 in a fluid cylinder 25 which oscillates the impeder 24 back and forth. The impeder may be similar to that described in Specifications 772,279 and 811,251. Cooling means 34 may be provided to spray fluid on the core. In a further embodiment a flat strip S, Fig. 4, is drawn through a die 40 of phenol formaldehyde resin possibly laminated with glass fibre to shape it to gapped tube form as it advances with a cable 12<1> which may be insulated and moves preferably but not necessarily at the same rate of advance. An insulated spreader 45 which may be cooled and which may have ceramic inserts extends into the gap and has a metal " shoe horn " 50 extending therefrom beyond the weld point to eliminate internal flash, a roller 52 pressing the tube beyond the weld point against a raised portion 50a of the shoe horn. A scraper 55 may engage the welded seam. The Specification refers to the use of a non-magnetic core, e.g. a multiconductor insulated cable and to a magnetic core which may be reciprocated and/or rotated in the tubing. U.S.A. Specification 2,818,489 also is referred to.

Title: Improvements relating to the automatic voltage regulation of electric generators
IPC: H02J7/16
Filed: 1934-06-13
Abstract: 439,955. Automatic regulation of variable speed generator systems ; charging and discharging batteries. STONE & CO., Ltd., J., Deptford, and NIXON, L. R., 54, Sidewood Road, New Eltham, both in London. June 13, 1934, Nos. 17521 /34 and 12696 /35. [Class 38 (iv)] An alternating-current generator 1 has a field winding 6 excited from the A.C. terminals through a rectifier 7 and a low-pass filter 8 comprising inductance 9 and capacity 10 which is adjusted and arranged to vary the field current with frequency so as to regulate the generated voltage. Two or more lowpass filters may be provided in cascade and may comprise series inductance and shunt capacity adjusted so that the field current is decreased with increasing speed of the alternator so as to maintain the output voltage constant. The field winding may be supplied from an auxiliary armature winding on the alternator alone or in series with the main armature winding. In the former case the inductance is wholly or in part embodied in the auxiliary armature winding. The characteristic of the filter is adjustable by a resistance 11 in parallel with the inductance 9. As applied to a train lighting system the alternator is of the inductor type and supplies a battery 3 and lamps 4 through a rectifier 5 which obviates the use of a reverse cut-out. The generator may primarily be a D.C. generator with the field current taken through the filter &c. from auxiliary slip rings connected to the commutator or armature so as to yield A.C. The invention may be applied to multiphase alternators. The second Provisional Specification describes an arrangement in which the generator has a constant current characteristic or a characteristic between a constant current and constant voltage characteristic by incorporating inductance in the load circuit by a choke and/or by suitable design of the armature of the generator. The arrangement may be used with or without the field control described above.

Title: Improvements in the treatment of artificial filaments and like products
IPC: D06M13/08
Filed: 1931-06-18
Abstract: Artificial filaments, threads, yarns, and like materials containing organic derivatives of cellulose particularly materials of low extensibility obtained by wet spinning or by dry spinning with stretching, are treated with organic solvents, latent solvents, or swelling agents, in the absence of tension sufficient to stretch them, and preferably they are allowed to shrink, whereby the extensibility is increased with little or no loss of tenacity. Treatment with shrinking agent is carried out in the absence of or with low tension.  If higher tension is employed, it is subsequently decreased or removed to allow the material to shrink.  The shrinking agent may be acetic, formic, or lactic acid, acetone, diacetone-alcohol, mono- or dimethyl or ethyl ether of ethylene glycol, glycol monoacetate, methyl glycol mono-acetate, dioxane, ethers of propylene glycol, ethers of diethylene glycol, phenols, acetins, dichlorethylene, ethyl lactate, or diethyl tartrate.  Latent solvents such as chloroform, methylene chloride, ethylene chloride, tetrachlorethane, or ethyl acetate may be used in the case of acetone-soluble cellulose acetate.  The shrinking agent may be diluted with water, glycol, glycerol, benzene, toluene, xylene, benzine, petrol, kerosene, carbontetrachloride, trichlorethylene, perchlorethylene, tetrahydronaphthalene, or decahydronaphthalene. The shrinking agent is applied in the form of vapour, or by spraying, dipping, or padding methods.  The yarns may be treated loose, in hanks, on bobbins, on swifts, in cakes or in other package form.  By providing resilient bobbins, shrinkage may be allowed while the yarn is in package form, or it may be wound off, allowed to shrink, and rewound at a slower winding speed.  If the yarn is wound loosely, shrinkage may take place even on non-resilient bobbins.  The process may be carried out continuously with wet spinning, or dry spinning with stretching and the softening agent remaining on the filaments after the stretching operation may be utilized as the shrinking agent.  The process may be applied to yarns in warp formation.  If desired the yarn may be dried without washing out the shrinking agent.  Specifications 177,868, 179,234, 277,089, 323,790, 336,217, [all in Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 362,939, 370,430, 371,461, 378,074, and 378,858 are referred to.  The Provisional Specification also includes local treatment with the shrinking agent.

Abstract: 1,049,224. Orienting sweets; endless conveyers. AEL-FOOD MACHINERY DIVISION Inc. April 29, 1964 [April 29, 1963], No. 17886/64. Headings B8A and B8S. Sweets, Fig. 1, are dropped on mass on to endless belt 26 which conveyes them on to disc 30 which is vibrated circularly so that only sweets in end-to-end orientation are delivered along channel 36 and are then conveyed by endless belt 113 to pusher 142 which pushes them one by one into the recesses 24 of wheel 23 which conveys them step-by-step to the next station. Disc 30 (Figs. 2, 3, not shown).-Disc 30 receives sweets from belt 26 and is provided with a slope 99, a ridge 28 and a guide 104. Additionally disc 30 carries channel 36 and adjustable guide 32. A guide 93 is also provided which is carried by the stationary framework and operates switch 33 when the accumulation of sweets on disc 30 is excessive to control belt 26 to reduce the supply thereto. The sweets travel round the disc 30 and are guided by guide 104 to pass in direction 31 and travel along slope 74 till those sweets which are misaligned are pressed by guide 32 over ridge 28 and fall back on to the flat part of disc 30 to be recirculated. Those sweets which are properly aligned are further orientated by elements 110 secured to the disc and are discharged along channel 36. Detectors 129 (Fig. 6) are positioned over belt 113 in said channel so that when the belt is filled with sweets switches are operated by the detectors to reduce the vibration of disc 30 so as to reduce discharge therefrom. Pusher 142 (Figs. 11, 12, not shown).-Sweets are fed along by belt 113 till the foremost sweet meets sensing stop 114 which serves automatically to cause pusher 142 to move the sweet past pivoted element 144 into recess 24 of wheel 23. Pusher 142 is carried by parallel members 155 and 156 which are operated from constantly rotating shaft 141 whenever solenoid 168 is energized by the impact of the foremost sweet on stop 114. Operation of solenoid 168 pivots lever 163 about pivot 164 and removes shoulder 166 from cam 167 to permit the single rotation of member 162. Member 162 is coupled to rods 155 and 156 through crank arm 177, inclined pin 190, element 189, journalled pin 187 and crosshead 198, the pin 187 being additionally carried by bar 182 pivoted in the side walls 172 and 173. One rotation therefore of element 162 causes a reciprocation of the pusher 142 whenever a sweet is in place.
