Title: Improvements in or relating to induction coils
IPC: H01F38/12
Filed: 1922-04-26
Abstract: 199,879. British Lighting & Ignition Co., Ltd., and Turner, E. O. April 26, 1922. Transformers.-Induction coils, particularly intended for use as ignition coils for internal-combustion engines, are made with a nearly closed magnetic circuit, one or more air gaps being provided of a size just suflicient to ensure a low value for the idle flux and quick demagnetization on breaking the primary circuit. The theoretical considerations governing the dimensions of the gaps are discussed in the Specification, and it is shown that the total length of the gaps should not be less than 2.5 or more than 60 times the ratio of the length of the iron path to the maximum flux density developed at an air-gap face. A single gap in the middle of the core on which the coils are wound, or a central gap with additional gaps at the ends of this core, may be provided. In another arrangement, Fig. 1, gaps e are left between the central core a and the lateral cheeks d, d<1> and connecting members f, f<1>. In modifications of the arrangement the gaps are left between the central core a, and the lateral cheeks, the central core in some cases passing through holes in the cheeks, as shown in Fig. 10. In the arrangement shown in Fig. 6, the gaps e are formed between overlapping members g, g' secured to the central core a. The opposing faces of the air gaps may be so arranged that the flux passes across the gaps in the plane of the laminations composing the core.

Abstract: 808,056. Packages ; cartons. ARENCO, A. B. April 10, 1957 [April 17, 1956], No. 11774/57. Classes 18 and 94(1). A cigarette package is closed by tucking in the upper end of the its front wall, folding down the triangular side flaps thus formed and then folding the upper end of its rear wall over the side flaps, a reinforcing strip of relatively rigid material provided with a closure tongue being attached to the inner or outer face of the upper end of the rear wall so that the tongue projects and is adapted to be inserted into a slit in the front wall or its tucked end, or in a reinforcement covering the front wall. The open-ended package shown in Fig. 3 is formed by folding a blank 1, Fig. 1, along lines 30, 31 and attaching a cardboard reinforcing strip 2, Fig. 2, which is folded along transverse lines 7, 8 and 9 to form panels 13, 14, 15 and 16 covering respectively the front wall 19, the bottom wall, the rear wall and the rear closure flap 21a of the package, the shaded areas of the strip being coated with thermoplastic or other adhesive. The upper edge 27 of the adhesive area coincides with the upper edge 5 of the flap 21a and is spaced a short distance from a folding line 10 which defines a tongue 18 having an arcuate edge 26 which may be inserted into an arcuate slit 11 in an area 28 of the panel 13 which is free from adhesive. The blank 1 is formed with lines of weakness 3, 4, e.g. perforations, defining an area 12 coated with thermoplastic or other adhesive. The adhesive also covers narrow marginal areas 29 outside the lines 3 and 4. After insertion of a batch of cigarettes, the front flap 19a is tucked in, thus folding the side flaps 20a along inclined lines 23, Fig. 4, and the triangular side flaps thus formed and the rear flap 21a are then folded along lines 24 and line 6 respectively, as shown in Fig. 5, so that the underside of the flap 21a adheres to the coated area of flap 19a. The tongue 18 is then folded down along the line 10 so that it adheres to the coated area of the front wall 19 and covers the slit 11, as shown in Fig. 6, and is finally secured by a sealing strip on stamp B. To open the package, the seal is broken and the tongue pulled upwardly to tear the wall 19 and flap 19a along the lines 3, 4, thus removing a strip C, Fig. 7, to leave an aperture through which the cigarettes may be removed. The package may then be reclosed by inserting the tongue 18 into the slit 11. In modifications, the strip 2 is attached to the inside of the package, the slit 11 is formed in the wall 19 or at its upper edge, the strip consists merely of the panels 15, 16 and 18 or is in two parts with the panel 14 omitted, or the blank 1 is formed with an aperture corresponding to the area 12 so that no strip C is required to be removed.
