Title: Improved machine to automatically manufacture transformers
IPC: H01F41/02
Filed: 1962-04-27
Abstract: 931,933. Making transformers. R. L. J. RUELLAN. April 27, 1962 [May 5, 1961], No. 16275/62. Class 83 (2). A machine for automatically applying laminations of magnetic material to a preformed coil to construct a transformer, said laminations being of two complementary shapes, said machine comprising means for holding said coil, a magazine on each of two opposite sides of said coil for holding laminations of each of said two shapes, means on each magazine for removably exposing the laminations therein one at a time, a carriage mounted to reciprocate past said exposed laminations and catch means thereon for moving a lamination from each magazine into the coil and guide means adjacent said coil holder for guiding the laminations into a stack interfitting with said coil. The coils 12 with their windings 13 are held in a magazine 11, the central upper portion of which has two ramps each formed by a flexible member 15, and also has on each side two ramps 17 leading to horizontal portions 16, and ramps 19 leading to flat parts 18. On each side of the coil holder is a double magazine 1, 2 provided with recesses 3, 4 to hold E-shaped laminations 7 and recesses 5, 6 to receive I-shaped laminations 9. A stop 8 under each recess 3, 4 is positioned to allow only one lamination at a, time to leave the magazine Below each recess 5 6 is an adjustable stop 10. Reciprocating beneath the magazines 1, 2 is a carriage 20 which comprises longitudinal members 21 and transverse members 22, the longitudinal members each have a groove 23, terminating in abutments 24, 25. When the carriage moves from right to left the abutment 24 catches an I-shaped lamination 9 and an E-shaped plate 7 which falls on top of the I-shaped plate. The leading end of the plate 7 is raised by the flexible member 15 and by the ramps 19. The lamination 9 is raised by the ramps 17 and pushed into position under the plate 7. When the hole in the coil is almost full the members 15 enter chamfers 31 and the last reciprocation of the carriage brings two plates 7 into place and during this movement the stops 10 are raised so that the carriage does not pick up I-shaped plates. The finished coil is automatically ejected when all the plates have been fitted, the flexible members 15 allowing it to pass. In a modification the coils are supplied from the top of the device and the coil support is arranged to open to permit the introduction and removal of the coils.

Abstract: 1463083 Reinforced flexible conduit ATCO RUBBER PRODUCTS Inc 11 April 1974 [11 April 1973] 16295/74 Heading F2P In a flexible conduit comprising a liner 14, a helical reinforcing strand 12 and a cover 16, the components of the conduit are held in their assembled configuration by pressure sensitive adhesive. In the embodiment shown the liner 14 is of unitary sheet construction and the inner face of the helically wound overlapping tape forming the cover 16 has pressure sensitive adhesive to bond the overlap as well as to bond the cover to the strand and liner. In another embodiment (Fig. 3, not shown) the inner liner consists of a helically wound tape 14<SP>1</SP> with adjacent turns overlapping. In this case both the inner face of the tape 16 and the outer face of the liner 14<SP>1</SP> have a pressure sensitive adhesive. The conduit is formed by helically winding the strand 12 and tape 16 around the liner using a mandrel of the type shown in Specification 1,451,469. Although the pressure which the wrapping causes between the overlapping surfaces is adequate to unify the assembly the conduit may be subjected to heat and/or further pressure. The conduit may be cylindrical or of other cross-section, e.g. polygonal, or oval. The reinforcing strand 12 may be of metal wire or of a flexible polymer and more than one strand may be incorporated in the conduit. The outer wrapping 16 and the inner liner 14 (or 14<SP>1</SP>) may be of polymeric materials, laminates of polymers and metal foil and/or paper, laminates of cloth and polymers, cloth alone, fibreglass reinforced polymers or from polymer ribbon stock. Any suitable pressure sensitive adhesive can be used.

Abstract: 458,735. Hats. FISCHEL, F., Alma Lodge, Wellington Road, and CARRINGTON & SONS, Ltd., S. R., Cale Green, both in Stockport. June 12, 1936, No. 16395. [Class 63] [See also Group XXIV] Finishing.-Relates to hat body brushing machines wherein a cone carries the hat body and is rotated alternately in opposite directions while brushes resting on the hat body are automatically moved over the surface, and consists in hinging the brushes to arms which can be swung to allow change of work, and which are pivoted to oscillated arms which reciprocate the row of brushes longitudinally of the hat body. Bevel friction wheels allow slip in case of undue resistance to the drive of the hat body. Reversing mechanism comprises a hollow lever partly filled with mercury. The cone 3 is driven by a friction bevel 28, the shaft driving a worm wheel 26 driving a pair of eccentrics linked to discs 16, 21 each of which is linked to an arm 5 pivotally carrying a number of brushes 13 normally resting on the hat body. The arm 5 is supported, in operative position, by a roller 43, and in workchanging position by a stop 42. The wormwheel also drives a disc on which is a pin 40 co-operating with a pivoted arm carrying a weight 38 co-operating with a hollow lever 37 partly filled with mercury and moving with an arm 35 actuating a sleeve 31 slidable along the driving shaft 32 and carrying a pair of friction bevel wheels 29, 30. In operation, a felted hat body is secured on the cone 3 and the machine started. The cone revolves and the brushes reciprocate in the direction of their carrying arms until the pin 40 lifts the arm on which is the weight 38 to just beyond vertical position. The arm falls and reverses the drive, this alternate reversal being continued till an automatic stopping motion operates. A rose may be mounted above the cone, for spraying the work during brushing.

Abstract: 885,774. Electromagnetic interaction pumps. ENGLISH ELECTRIC CO. Ltd. May 23, 1958 [May 24, 1957], No. 16534/57. Class 35. The pressure developed in a linear induction interaction pump is increased by passing the duct several times in series through the working field. In one form, Fig. 1, the liquid duct 12 is carried several times between travelling-field cores 10, 11 and returned repeatedly to the start end 20 by loops 19 so as to form a spiral. The active duct-portions lie side by side in the air gap and are in electrical contact to allow lateral current flow through the ducts in succession, conductors 22 being secured to the outside edges of the outer ducts to facilitate current circulation. In a modification, the return loops are in the same plane as the ducts in the working gap, thus forming a single flat-spiral circuit. Alternatively a single central duct may be split as it leaves the core to produce flat spirals on either side of itself. The return loops may pass through an additional field member, and it is described how the ducts may be of rectangular spiral configuration with a field member on each side, or an even larger number of field members may be disposed on an appropriate polygon. Alternatively the duct may pass in zig-zag fashion through a stack of field members. Fig. 8 shows the application of the invention to a pump of radial type having an axially travelling flux produced by a suitable winding in the outer core 81. The annular duct is divided into four sectors 84, 85, 86, 87 connected in series by means of central ducts 88, 89, 90, 91.
