Title: Improvements in or relating to tools for making an electrical connection between an electrical terminal and a contact
IPC: H05K13/04
Filed: 1955-02-08
Abstract: 799,599. Assembling force fits; embossing. AMP, Inc. Feb. 8, 1955 [March 8, 1954; Feb. 8, 1954], No. 3720/55. Class 83 (4). A tool for making an electrical connection between an electrical terminal and a contact, one of which provides a recess for receiving in frictional engagement a plug portion of the other, comprises a shank member having at one end a longitudinal recess for receiving the terminal, shoulder engaging means being provided at or adjacent the outer end of the recess having stop-flanges for engaging shoulders projecting away from the terminal and at least a part of the wall of the shank being open so as to receive a wire or similar conductor secured to the terminal. The shank recess 2 has a flared opening defined in part by inclined faces 3 each of which has a marking die 4. The terminal is positioned in the recess with its shoulder portion 11, 11a between the faces 3 and its wire extending along the recess. The terminal is then engaged with a contact 12, 12a and telescoped together by manual pressure on the tool handle, or by impact, or both. In an embodiment the shank is mounted on a spring-loaded plunger 13 accommodated in a holder 14 which houses a spring-loaded hammer 16. The plunger passes through a plug 18 in the holder which also serves as an abutment for the plunger spring 15. The middle portion of the holder bore has a sloping cam surface 20. The hammer has an annular flange 16a at its lower end, a central hole 16b and a transverse recess 21 for accommodating an apertured slidable detent 22. A flat spring 24 urges a rounded portion of the detent against the holder bore so that a shoulder 27 on the plunger engages the detent. In operation pressure is applied to the holder to engage the terminal and contact and when frictional contact between the parts increases sufficiently the plunger moves inwardly and compresses the spring 17 until the hammer movement brings the detent against the cam 20 and dislodges it from the plunger shoulder 27 whereupon the hammer is released to deliver a sharp blow on the plunger to effect a good connection and emboss the terminal. In a modification the recess 2 is not formed as a channel but is closed at its outer end by a wall which is divided by a transverse slot into opposed flanges which engage under projecting portions of the terminal and may be used for extracting the terminal from the connector. Specification 799,598, [Group XXXVI], is referred to.

Title: A process for the production of photomechanical printing formes
IPC: G03C5/315
Filed: 1957-02-07
Abstract: 821,507. Photomechanical printing plates, producing. AGFA A. G. Feb. 7, 1957 [Feb. 25, 1956], No. 4247/57. Class 98(2) The process of Specification 821,506 is adapted to the production of silk screen and lithographic printing surfaces, thus an exposed silver halide emulsion layer containing a tanning developing substance, with or without a preliminary operation of heating to 80-150C., is heated at this temperature in contact with a transfer layer to transfer unexposed emulsion thereto and then either or both of the resulting relief images are dyed with a printing ink. Thus the positive, transferred, image may be dyed taking care not to dye its support and placed on the material to be printed, which latter has been previously damped so that dye may transfer thereto, or the positive, transferred, image may be further transferred to a roller before this procedure, or with use of a hydrophilic support may be treated as with zirconium oxychloride to make it ink-absorbing and used lithographically. The negative, when on a permeable support, may be used in the silk screen printing process. Examples are directed to (1) this latter process, using the negative only, (2) and (3) the dye-transfer process from the positive with water as transfer liquid, and (4) offset printing from the positive. Numerous substances and supports for use in the process are described in the examples and elsewhere. The final results are referred to as being non-laterally reversed but exposures for such results are not detailed. Specifications 655,273 [Group XXX] 790,811 and 801,053 also are referred to.

Abstract: 1,101,652. Superconductors. SIEMENSSCHUCKERTWERKE A.G. 1 Feb., 1965 [30 Jan., 1964; 17 Dec.. 1964], No. 4361/65. Heading HlK. A superconductive coil has filamentary resistive material connecting adjacent turns of the coil, the resistance being high enough to obtain current build up within a reasonably short time but low enough to provide a path of lower resistance than the wire of the turns so that transition from superconductive to normal state occurs rapidly without the occurrence of local hot spots. The Figure shows a coil of superconductor wires 4 separated by conductive filaments 10 of glass wool impregnated with conductive varnish or resin continuously or at spaced intervals. Insulating material 2 of polyethylene terephthalate and copper foils 6 separate the coil layers; the foils may be slotted and connected to the superconductive wire portion between two layers and serve to conduct away heat during transitions. The space in the coil may be filled with a resistance paste comprising graphite, carbon or metal particles. The superconductor wire may be protected with a thin coating of silver, gold or copper. The superconductor may consist of Nb-Sn or Nb-Zr. The assembly may comprise cavities containing evaporable liquids such as nitrogen or water to increase the thermal mass.
