Title: Improvements relating to machine and other vices and like work holding or setting appliances
IPC: B25B1/20
Filed: 1919-12-09
Abstract: 159,065. Secord, W. L. Dec. 9, 1919. Vices.-A machine or other vice comprises three jaws, each pivotally mounted for angular adjustment and independently traversable by a traversing-screw. In the form shown, the bed a has an elevated surface a<2> which is slotted in T- form at a<3>, a<4>, a<5>, providing guides for the traversable nuts f, h, j, on which the jaws c, d, e are mounted. Each jaw is supported on a spigot, such as f<2> projecting from the nut f, and may be fixed in angularly adjusted position by a bolt m. By interposing a washer m<2>, Fig. 2, the jaw is held out of contact with the bed so that it is still traversable by its screw g although fixed in angular position. A square part f<3> guides the nut in its slot. Each jaw being free to swing round completely on its supporting spigot, the device may be operated to grip an object internally by swinging the three jaws round so that their backs face each other.

Filed: 1948-11-26
Abstract: 650,296. Stoppers. ZALASIEWITZ, H. Nov. 26, 1948, No. 30807. [Class 125(iii)] A stopper for bottles &c. having cones 8, 9 which, when moved towards one another, expand the body 3 of the stopper radially against the bottle neck, is characterized by the middle zone of the stopper being incapable of radial expansion, whereby an air space is maintained between two zones of contact with the bottle neck so that when the cones are again separated, removal of the stopper is facilitated. The body 3 may be made by vulcanizing expansible end sleeves or sheaths to a non-expansible middle part, but, as shown, the whole of the body is in one piece and is of expansible material, a metal ring 12 holding the middle zone against radial expansion. The cone 8 is formed on a closure plate 2 which is knurled so that it may be held against rotation. A head 1, rotatable by wings, has a threaded bore 6 in which screws the head 5 of a square section rod 4 carrying the cone 9. The rod 4 passes through a square hole in the cone 8 so that it is held against rotation during the turning of the head 1. In a modification, the closure 2 is dispensed with, the cone 8 being carried by the head 1 which, in this case is not rotatable, the rod 4 having rack-teeth which are engaged by a pinion pivoted in a slot in the head and operated by a lever.

Abstract: 751,942. Capacitors. ERIE RESISTOR CORPORATION. Oct. 27,1954 [Nov. 4, 1963], No. 30976/54. Class 37. Capacitors comprising a dielectric (e.g. ceramic) disc 1, Fig. 1, having electrode coatings to which are attached leads 4, 5 formed on the two surfaces thereof, are manufactured by arranging a plurality of hairpin-shaped pieces of soft metal, Fig. 3, side by side in a row, inserting metallized discs 1 between the crossedover ends 6, 7 of the hairpin members and applying a clamping pressure to the arms 4, 5 of the hairpin members by clamping together two pieces of card or other clamping means extending across the width of the hairpin members, one above and one below the plane thereof, so that on the application of pressure the discs 1 are gripped between the crossed-over ends 6, 7 the discs 1 thus held being then subjected to a dip-soldering operation. Subsequent operations which may be carried out while the discs are still supported by the clamping means are dipping in plastic to provide an insulating cost. ing, stamping capacitance values on the insulating coating and wax impregnation. In a first embodiment of the invention an initial twist is given, as shown in the side view of Fig. 6, so that on clamping together the arms 4, 5 between the cardboard strips 10, 11 sufficient gripping force is provided between the ends 6, 7 to support the capacitors 1. The cardboard strips 10, 11 are held together by staples 12, 13 as shown in Fig. 5. The loops of the hairpins are subsequently cut to provide the finished capacitors as shown in Fig. 4. In a modification, Fig. 11, additional gripping force between the ends 6, 7 is provided by means of further clamping members 14, 15 the jaws of which are so shaped as to apply a reverse twist to the arm of the hairpins on the remote side of the cards 10, 11, Fig. 12 (not shown). In the arrangements so far described the finished capacitors are obtained mounted on the strips 10, 11 which are provided with slots 25 whereby they may be assembled in an appropriately constructed container. In a further modification, Fig. 13 (not shown), the cardboard strips are replaced by clamping members having rubber-faced jaws and from which the capacitors are removed when their manufacture is completed. Fig. 16 (not shown) illustrates a further modification wherein each capacitor disc is attached to the adjacent arms of adjacent hairpin members.

[Also in Division C7] Razor blades and similar tools are made from steel containing at least 8% of chromium, which after cold working is austenitized at a temperature not less than 850‹ C., at which carbides are substantially all dissolved, is then rapidly cooled, e.g. between water-cooled blocks, to produce a structure containing both austenite and martensite, and is then heat-treated at a temperature above 600‹ C. but below the austenitizing temperature. After the above treatment the steel may be further coldrolled before being formed to shape; it is then hardened from a temperature in the range 850‹ to 1150‹ C. by cooling to room temperature or to a temperature in the range - 20‹ to - 120‹ C., possibly followed by tempering in the range 100‹ to 275‹ C. after which the cutting edge is formed as by grinding. Finally, a fluoro-polymer coating may be applied, necessitating heat-treatment at a temperature above 150‹ C.
