Title: Improvements in or relating to electric transformers
Inventor: NUTTALL THOMAS CAYTON
IPC: H01F27/28
Filed: 1950-12-08
Abstract: 695,222. Transformers. CINEMA-TELEVISION, Ltd. Dec. 7, 1951 [Dec. 8, 1950], No. 30108/50. Class 38 (ii). An electric transformer comprises a winding consisting of two similar multi-layer sections of which the second is wound directly on the first, but in the opposite direction, the two sections being connected effectively in parallel. In the embodiment shown, on a bobbin 2 is wound one half, 3A, of the secondary winding. Over this is wound one half, 5A, of the primary winding of the required number of turns and of a conductor having half the required cross-sectional area for this winding. The bobbin is then reversed on the winding machine and the other half, 5B, of the primary winding applied, having the same number of turns and of the same conductor as the first half, 5A, thereof. Finally the remainder, 3B, of the secondary winding is applied. The two adjacent ends of the primary winding sections are then effectively connected together and this is made the high potential terminal of the winding, whilst the remote ends of the winding together form the low potential terminal. Thus the high potential portions of the primary winding are remote from the secondary winding with concomitant easing of the insulation problem of the transformer. Also the leakage inductance and self-capacitance characteristics of the transformer are reduced. Specification 512,519, [Group XL], is referred to.

Filed: 1972-06-29
Abstract: 1378697 Blow-moulding SIEMAG SIEGENER MASCHINENBAU GmbH 29 June 1972 [1 July 1971] 30475/72 Heading B5A Hollow articles having a neck part are formed by dipping a blow mandrel into a chamber in a hollow member, the chamber being filled with plastic material, injection moulding the neck part around the blow mandrel in a mould adjacent the orifice of the chamber, withdrawing the mandrel having a layer of material entrained thereon forming a preform, enclosing the mandrel and preform in a blow mould and blow moulding the article. As shown, a press operable by cylinder 24 on columns 22 raises or lowers a platen 27 through piston-rod 25 and studs 26. On platen 27 is mounted cylinder 30 to slide a guide slide 29 horizontally within guide blocks 28 on platen 27 so as to move two mandrels 2 between a central blow-moulding position and outer preform-moulding positions. Each chamber is formed in a body 34 having a sleeve 37 screwed thereinto forming at its lower end a shoulder against which a plunger 10 abuts at the upper end of its stroke to cut off communication with an extruder (not shown). The mandrels 2 are lowered, one into blow mould 32 and the other into body 34, injection into neck mould 45 46 being effected simultaneously with blow moulding. Platen 27 is then raised so that mandrel 2 is withdrawn from body 34, plunger 10 rising at the same rate to extrude the preform around the mandrel while the blow mould parts open. The neck mould parts 45, 46 are opened and the article stripped before guide slide 29 is traversed to present an empty mandrel at the left-hand chamber and a preform at the blow mould. Platen 27 is lowered, closing the blow- ' mould, for further blow-moulding and preformmoulding steps. A guide block 31 is mounted transversely on platen 27, blow mould halves 32, 33 sliding thereon. They are closed on lowering of platen 27 by engagement of bores 36 therein with inclined pins 35 mounted on lower platen 21. Neck mould parts 45, 46 are mounted on slide 29 and are similarly opened by means of inclined pins 54 when moved downwardly by stripper plate 52 which also strips the blown article 47 into a shoot 58 carried by arms 56, 57 from platen 27 and cooled by movable nozzle 59. Stripper plate 52 is moved downwardly by studs 51 against springs 53 through thrustring 50, tappet pins 49 and cylinder 48. Mandrel 2 is formed as a poppet valve for supply of blowing fluid, the central portion thereof being lowered against spring pressure by cam 44. The mandrels, which may alternatively be mounted on an indexing plate, may be coated with a release agent, e.g. P.T.F.E., and may also be used to stretch the preform and to fill the blown articles.
