Title: Improvements in or relating to valve circuit arrangements for very short waves
IPC: H03F1/08
Filed: 1936-06-08
Abstract: 459,348. Valve circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 8, 1936, No. 16014. Convention date, June 8, 1935. [Classes 40 (iii) and 40 (v)] In an ultra short-wave valve circuit of the adjustable back-coupled type, the sliding contact A connecting the H.T. supply to the loop inductance L, Fig. 1, is kept at a constant impedance by housing the valve R and loop L in a circular space cut in a metal plate E, Fig. 2, the contact being constituted by a metal strip A sliding along the loop L and also connecting with a metal quadrant Z connected to the H.T. supply and insulated from the plate E by a very thin layer of insulation, whereby Z and E are both approximately at zero high-frequency potential. The same system may be employed for a push-pull backcoupled arrangement, also of the three-point type, Fig. 3 (not shown).

Title: Improvements in or relating to locks and padlocks
IPC: E05B35/00
Filed: 1938-05-30
Abstract: 515,358. Locks. SEBESTYEN, F., and KARACSONY, I. May 30, 1938, No. 16064. [Class 44] One or each edge of a key is formed with teeth, inclined to the axis of the key, the tumblers of the lock being correspondingly grooved so that as the key is pushed into the lock the tumblers are progressively moved by successive teeth sliding in successive grooves. In the revolving barrel lock shown in Fig. 1. the barrel 3 is locked by the projecting end of a tumbler 11 abutting a stop 15. Each tumbler has inclined grooves 17. Fig. 5, the grooves being cut in both directions so that the key, Fig. 8, can be inserted from both sides of the lock. When the key is pushed into the barrel the tumblers are moved clear of the stop 15 and the barrel can be turned by the key to shoot or withdraw the bolt by means of an arm 4 carrying a pin engaging a cam slot 6 in the bolt. In a modification, four tumblers surrounding a cross-shaped keyhole are either cut away where they intersect so as not to interfere with each other as shown in Fig. 14, or are formed with bevelled serrated ends 37, Fig. 25, which permit simultaneous movement of all the tumblers but prevent movement of a single tumbler by a picking implement. The bottom of the lock casing has an annular rib which is interrupted in four places to form notches to receive a lug 21, Fig. 14, on each tumbler to lock the barrel. The invention is also described as applied to locks with non- rotating keys. In the form shown in Fig. 17. the tumblers 11 have notches 25 which, when aligned with stumps 26 on the bolt, allow the bolt to be operated by a handle follower 27. In a modification, the tumblers are fixed to a sliding plate, gated in the usual manner to co-operate with the bolt stump. In another modification, sector-shaped gated tumblers, pivoted to the lock casing, are used, on edge of each tumbler, concentric with the pivot, being grooved to suit the key. In a modification applied to a padlock, two sliding tumblers, moved in opposite directions by the key, each engage a notch in one limb of the swivel. In another form of padlock, Fig. 22, ring-shaped tumblers 33 surround one limb of the swivel 32. This limb has a longitudinal groove 36 and a'number of circumferential grooves 35, one for each tumbler. Projections 34 in the bores of the tumblers engage the circumferential grooves in the locked position. When the key is inserted, the projections are aligned in the longitudinal groove, enabling the swivel to be removed.

Filed: 1938-06-03
Abstract: 515,692. Moulding glass. COMBINED OPTICAL INDUSTRIES, Ltd., and WILLIAMS, W. E. June 3, 1938, No. 16749. [Class 56] [Also in Group V] In moulding glass by pressing between dies I, 2 having jackets 13 for heating and cooling fluid, the dies and jackets are so constructed and arranged that the isothermals in the dies, during setting of the material, have curvatures coincident with, or are disposed parallel or convex to, the moulding surfaces of the dies whereby the material sets simultaneously and evenly throughout, or begins to set from the centre outwards. Optical defects or warping due to internal strains on setting are thus avoided. In one form, the interior surfaces of the heating jackets and of the dies in contact therewith are shaped similarly to the moulding surfaces. In other forms the jackets have plane faces. For moulding flat discs, the dies are provided with external guard rings, such as 14, 15, of material, such as steel, having the same conductivity as the dies so that the cooling of the plastic material is substantially uniform. The gap 16, between the rings is made as small as possible and may be further protected by an auxiliary ring. An insulating sleeve 17 of asbestos paper may be provided. For moulding a lens 18, as shown, the dies 1, 2 are of uniform thickness and conducting bodies 19, 20 are disposed between the dies and jackets 13. The bodies 19, 20 and guard rings 14, 15 are formed of material such as copper or a copper-silicon alloy having a' higher conductivity than the steel dies. The upper ring 14 may be provided with a steel annulus 14a. For convex lenses, in order to extract more heat from the centre of the lens, the bodies 19, 20 may be convex towards the lens, so that the isothermals'are similarly convex. In addition, for a very thick lens, the guard rings are made shorter and in the gap is provided a copper sleeve so as to retain heat at the periphery of the lens during cooling. The copper, sleeve may be heated electrically and encased in asbestos paper. Specifications 416,398 and 475,035, [both in Group XX], are referred to.

Abstract: 545,447. Electrolytic treatment of sliding-clasp fasteners. LIGHTNING FASTENERS, Ltd. (Talcon, Inc.). Nov. 23, 1940, No. 16836. [Class 41] Sliding clasp fasteners are electro-plated mounted on their supporting tapes 6 in the interlocked state by feeding between them a flexible ribbon-like conductor 12, Fig. 1, sufficiently thin to pass between and around the interlocking heads of the elements 2, the conductor ribbon being fed through a slot 11 in the wedge portion or "diamond" 10 of a tool 7 employed in the manner of a slider to effect the interlocking. The ribbon is connected to the cathode bar for an " oxidized " copper finish on fasteners of copper or copper alloy, or to the anode bar for producing an anodic finish which may subsequently be dyed on fasteners of aluminium or its alloys. The ribbon 12 may, as shown in Fig. 3, be of greater width than the fasteners, and its current carrying power may be increased by the formation of longitudinal ribs or thickenings. Fig. 4 shows in section a multiple tool adapted for the treatment of three sets of fasteners simultaneously by a single conductor ribbon. The assembling tool may also be adapted to treat simultaneously two or more sets of fasteners mounted on separate conductor ribbons.
