Title: Improvements in telephonic repeating systems
IPC: H04B3/14
Filed: 1924-12-19
Abstract: 226,560. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Dec. 22, 1923, [Convention date]. Repeating systems.-Speech currents that have been distorted in a long telephone line cannot in general be completely restored by counter distortion in an amplifier. The differences between the distortion and counter distortion for different frequencies can be plotted and furnish a curve such as b, Fin. 4. The invention consists in connecting across the leads to the amplifier, e.g. V1, circuits e.g. S1 tuned to the frequency or frequencies at which the curve b is at a maximum (or minimum). This has the effect of flattening the curve to the form c, Fig. 5, and the addition of ohmic resistance flattens it further to the form d. This process is repeated at each amplifier in succession, the measurements at each amplifier taking into account all the preceding sections. The use of separate ohmic resistance may be avoided by suitably adjusting the copper and iron losses in the oscillating circuits.

[Class 83 (iii).] A wheel lathe is provided with a tool-slide which simultaneously turns the sprung ring groove and the shoulder in the rims of railway wheels, the cross-slides for the respective tools being adapted to execute a movement in independent directions consequent upon the feed of the tool-slide. The tool slides 3, 4 carrying grooving and shouldering tools, respectively, are vertically slidable on a member 5 which is slidable horizontally along guides on the arm 6, adjustment being effected by a rack, and pinion on the end of a vertical shaft 7, Fig. 2. Cylindrical members 8, rotatably carried by each of the slides have slotted inside faces and carry extensions 8<1> on the outside which in conjunction with bolts 9 allow the position of the inside slots to be varied. The slot in the member carried by the lower slide is engaged by a block 11 which is rotatable about a pin 12 fixed to the arm 6, while the slot in the member carried by the upper slide is engaged by a block rotatable about a pin 13 carried on the end of a vertically adjustable bar 14 ; this enables, by rotation of the rod 18, the upper slide to be moved towards or away from the lower slide without affecting the inclination of the tool feed. Movement of the shaft 7 which effects the horizontal feed of the slides 3, 4 also gives the requisite adjustable inclined feed of the tools since the pins upon which the blocks 11 are carried remain stationary during the cutting operation.

Abstract: 1478065 Cold joining parts ELPAG AG CHUR 11 July 1974 [16 July 1973] 30803/74 Headings B3H and B3A In a method of cold-joining metal or plastics parts 2, 2, at least one insert 1 which is harder than the material of at least one of the parts 2 is located between the parts and the parts are moved towards one another under pressure so as to cause the insert to penetrate into an uninterrupted surface region of at least one part so that the insert is enclosed by the material of the one part to anchor it in the material. The insert 1 is a coil, e.g. of copper when the parts are aluminium plates, and it may be wound around a wire 4 or a strip. The plates may be displaced laterally when under pressure so as to deform the coil thereby providing improved anchorage for the coil, Fig. 4 (not shown). The insert may alternatively comprise a bar (6), Fig. 10 (not shown), of cruciform cross-section, a tongued strip (7), Fig. 14 (not shown), or a plurality of balls. The inserts may be formed as a grid or may be arranged in a sinuous pattern for securing tubular electrical heating elements to, e.g. frying pans, saucepans, tanks, kettles or hot plates, or for securing evaporator tubes in refrigerators. In the manufacture of a saucepan, Fig. 24 (not shown), a heating coil (21) is welded to the bottom of the saucepan, which is of stainless steel, while an aluminium plate (22) is pressed onto the coil until it is in contact with the saucepan. The sole plate of an electric iron is made by welding a number of balls (31), Fig. 31 (not shown), to a nickel-chrome steel plate (30) and pressing a heating element (32) and the steel plate (30) on to opposite faces of an aluminium plate (33) to secure them to it. The heating element is held on the plate (33) by wire coils (34) with cores (35) which become embedded in the plate and cover of the element, Fig. 29 (not shown). A heating element is similarly secured to the base of an electric kettle, Fig. 31 (not shown), or to the base of a tank, Fig. 34 (not shown). Longitudinally jointed pipes may have their seams secured by coils (59), (63), (67), (71), Figs. 39-42 (not shown). A can lid 73, Fig. 43, is secured to a can body 72 by a wire coil 75 and a ring 77 may be attached to the coil to assist in opening the can.

Filed: 1952-12-04
Abstract: 748,767. Photo-sensitive sheet for making a printing stencil. ECKARDT, C. Dec. 4, 1952 [Dec. 6, 1951; Sept. 30, 1952], No. 30843/52. Class 98 (2). A fibrous backing as of Yoshima paper is provided successively with (1) a diffusion layer of wax emulsion, (2) an intermediate layer of wax emulsion, and (3) a covering layer of hard resin emulsion with a light-sensitive substance which renders the layer water-insoluble on exposure to light. The diffusion and intermediate layers may be sensitized similarly, and the covering layer may contain, additionally, wax emulsion. In an example emulsions for the three layers comprise specified parts of (1) beeswax, ethyl sebacate, gum arabic, glycerin, ammonium bichromate and water; (2) similar to (1) but with omission of the glycerin; and (3) similar to (1) but with omission of the glycerin and addition of shellac and acetone. Each layer is dried after application, and the product may be exposed in the normal manner, developed in a water bath which is stated to wash out unexposed parts of the covering layer and parts of the intermediate layer lying therebelow but to let the diffusion layer remain, and dried to result in a stencil for printing. Albumin, gelatine, ceresin and stearin may be used in the emulsions and diazo sensitizers or silver salts may be used instead of bichromate. For printing, ink from a counter-pressure plate or cylinder, itself supplied from an inking roller, is supplied under pressure through to the diffusion layer and the paper, and darker or brighter tones may be produced in the impression by local variations in the height or resilience of the platen.

Title: Improvements in and relating to safety elements for projectile fuses
IPC: F42C15/22
Filed: 1953-11-09
Abstract: 745,110. Projectile fuzes. VERWAL TUNGSGES.DER WERKZEUGMASCHINENFABRIK OERLIKON. Nov. 9. 1953 [Nov. 21, 1952], No. 30969/53. Class 9(1) A safety device for percussion fuzes comprises at least one locking member in the path of the striker preventing premature ignition by the striker, which locking member is adapted to be released by centrifugal force on overcoming the resistance of a plastically deformable element holding the member in the locking position. Fig. 1 shows a cylindrical locking member 2 placed in a radial bore 1a of the fuze casing 1. The member 2 is held in contact with a ring 4 surrounding the casing by a helical deformable element 3. The bore la intersectsan axial bore lb for the striker. In Fig. 2 the cavity 5a in the fuze casing 5 contains an eccentrically placed member 7 held against the wall of the casing by a deformable metal strip 8. A slot 7a in the eccentric connects an opening 7b, Fig. 3, with a-countersunk bore 7c into which the striker 9 extends, a shoulder 9a being engaged by the bore 7c to prevent froward movement of the striker. In another embodiment a transverse locking bolt abuts a washer having three deformable lugs, the washer being held by a screw extending through a bore in the fuze casing. The washer may be integral with the bolt. Fig. 8 shows a fuze incorporating the device of Fig. 1 and mounted in the base 15 of a projectile. Centrifugal bodies 20 are pivoted on the striker 19, which is forced by a spring 21 against three pins 22 (one not shown) projecting from radial bores in the fuze casing 16. Resting on the conical outer ends of the pins 22 is a distance ring or piece 23 into which is telescoped a slotted ring 24 above which is an adjustment ring 25 screwed on to the casing 16 to prevent axial movement of the rings 23 and 24 and so lock the pins 22 during transport, the rings 25 being secured by a dowel pin 26. A trarsverse locking member 27 held by a deformable element 28 is interposed between the striker and a detonator 17. On firing the projectile, the slotted ring 24 sets back due to inertia and becomes wedged with ring 23. so that the two rings can move together. The striker 19 also sets back by inertia and the bodies 20 move outwards under centrifugal force exerting a rearward pull on the striker. When the centrifugal force reaches a predetermined value the member 27 moves outwards deforming the element 28 and frees the path of the striker. As the projectile decelerates the ring 23 moves forwards and the pins 22 escape thus arming the fuze, so that on impact the striker moves forwards into the detonator. The device shown in Fig. 3 is also mounted in impact operated fuzes, the locking member 7 being moved by centrifugal force tc deform the metal holding element and free the striker. Specification 653,547 is referred to.
