Abstract: 744,952. Magnetic recording and reproducing heads. CLEVITE CORPORATION. Oct. 7, 1953 [Oct. 21, 1952], No. 27550/53. Class 40(2) A magnetic head is formed by placing a core 10 of a magnetizable material with a winding 16 in a housing 20 of magnetizable material with a leaf spring 22, a paper spacer 21, and an electric contact in the form of a leaf spring 24, and then filling the housing with a liquid resin, e.g. epoxy resins and styrene polyesters. After hardening of the resin, part of the housing is removed to expose the non- magnetic gap 23, Fig. 6. The housing may have open ends one of which is temporarily closed during filling and hardening of the resin; the housing then being provided with end plates 27, 28, Fig. 8, which may be soldered in place. In a modification, the housing 20 and the plate 28 may be formed integrally as a single cup-shaped piece. The plate 27 may have an opening 29 for the ends 25 of the winding. The core 10 may be formed by inserting a shim of non- magnetic material in a longitudinal slot in a tube and then squeezing the tube shut on the shim. The tube is then cut into lengths and each length has a thin layer of insulation applied to it, except near the gap, by dipping in laquer or wrapping with insulating tape. The tube is squeezed in such a manner that the end faces of the gap are parallel, if desired the faces may be cut to converge towards the centre of the tube, so that when the tube is squeezed the faces become parallel. This matter relating to the formation of the core forms the subject-matter of Specification 744,970. When used with a kinematograph apparatus, a portion of the housing may be removed at 43 so that it fits under the flange 44 of the film flywheel 41.

Title: Improvements in and relating to water absorptive woven textile fabrics
IPC: D03D1/00
Filed: 1963-07-16
Abstract: In a fabric having a zone of greater shrinkage when wet than the body of the fabric, for example the decorative ends or the selvedges of a terry towel, a spiral yarn having a removable core is used to provide extra length in the more shrinkable zone and thereby prevent puckering of the fabric.  Examples are given of plied or cabled cotton yarn spiralled round a core or raw silk, which is removed by washing the fabric in sodium hydroxide solution; in the case of cabled yarn, the cabling twist is in the same direction as the plying twist, and is removed by the spirally operation to leave the plies lying side by side in the fabric when the silk is washed out.  Other core yarns mentioned include wool, protein fibre, viscose, alginate, cellulose acetate, and carboxymethyl cellulose; the permanent yarn may be viscose, cellulose acetate, nylon, or polyester.

Abstract: 1,014,718. Adjustable mountings. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 10, 1964 [July 15, 1963], No. 28573/64. Heading G2A. A plate (e.g. a perforated diaphragm) is mounted between two sections of a housing rotatable relative to each other, one section having a pin which engages in a slot in the plate, so that said rotating movement causes the plate itself to pivot and so bring different parts of it into register with an opening in one of the housing sections. The form shown is a diaphragm for use in optical apparatus. The housing has two shallow cylindrical parts 10, 11, a rim of one fitting over a flange of the other, so that they can turn relative to each other. Pins 16, 17 are secured in the lower and upper housing parts respectively, which parts also have coincident openings 14, 13. Within the housing is the diaphragm plate 18, of approximately elliptical shape, having two circular apertures 21, 22 of different sizes. The plate has slots 19, 20 at its ends, which slots fit slidingly over the pins 16, 17. If part 11 is turned relative to part 10, pin 17 carries plate 18 round so that it pivots on pin 16. Conversely, turning part 10 causes the plate to pivot on pin 17. Thus either aperture 21, 22 can be brought into a greater or lesser degree of registration with the central openings 13, 14.
