Abstract: 580,766. Autographic registers. WILLIAMS, W. P. (Standard Register Co.). March 23, 1944, No. 5428. [Class 106 (i)] An autographic register in which continuous strips of record material are progressively advanced predetermined distances past a recording position, comprises a reciprocatory actuator (32) and motion transmitting means by which the motion of the reciprocatory actuator in one direction is transmitted to the strip feeding mechanism. The actuator has, in addition to its reciprocatory motion, a rocking motion operating a locking engagement whereby the actuator is locked and unlocked. The casing, of moulded plastic, pulp or sheet metal, comprises a hinged lid 2, Fig. 1, with a writing aperture 6 widened to form an exit 7 for the inscribed strip which passes over a writing tablet 12, Fig. 4, from storage box 10. Transfer material 18, Fig. 3, is drawn manually from a roll at the side and clamped by a bar 24. Guide bars 21 with fabric strips 23 shield the transverse edges of the transfer material. A slide handle or actuator 32, comprising two studs 35 working in a slot 33, Fig. 6, is connected to a chain 29 passing round a pulley 28 which is geared to the paper-feeding pin wheels 14, Fig. 4, through a one-way ratchet-and-pawl device. Initial rocking of the handle 32 to lift one stud 35 from a notch 34 rocks an arm 37 comprising two studs 47, 38 which unlock (through detent 44) and lift a clamp bar and tear-off knife 42, thus releasing the paper for feeding. A notched wheel holds up the arm 37 until. completion of the feeding cycle when a lug on that arm falls back into the notch. The clamp bar 42 can be lifted higher for re-loading, and a finger 59, Fig. 3, on the lid 2 releases it from this higher position before the lid can be closed. A depressible hinged section 53 engages a lug 55 and through a pin-and-slot linkage opens a flap 5, Fig. 4, to allow storage of inscribed forms in a compartment 4.

Patent GB-903334-A (GB)
Title: Improvements in or relating to processes for making semi-conductor devices
IPC: H01L21/00
Filed: 1959-02-18
Abstract: An alloy for use in the manufacture of semi-conductor devices (see Group XXXVI) contains gold, antimony, arsenic, and oxygen in oxide form, the antimony, arsenic and oxygen constituting 0.2-5%, 0.0001-1%, and 0.001-1% by weight, respectively, of the total gold-antimony content.  The alloy may also contain a trace of sulphur.  A typical alloy is prepared as follows:  An antimony-arsenic alloy (A) is formed by melting together 95 grams of antimony and 5 grams of arsenic at 610 DEG  C.; partially oxidized antimony (B) is prepared by roasting 100 grams of powdered antimony in air at a temperature which is slowly raised to 635 DEG  C., to give an oxygen content of 2%, and an antimony sulphur alloy (C) formed by melting 100 grams of antimony with 2 grams flowers of sulphur at 625 DEG  C., 2 parts of A, 50 parts of B, and 10 parts of C are then heated with 38 parts antimony at 635 DEG  C. to form an alloy containing 1% arsenic, 1% oxygen and 1% sulphur.  The gold alloy is prepared by melting 100 grams of the resulting alloy with 300 grams gold at 360 DEG  C. to form an antimony gold eutectic.  400 grams of the eutectic are then melted at 1100 DEG  C. with 9600 grams of gold to produce the final alloy which may be rolled into a foil. The various stages in producing the alloy should be carried out in an inert or reducing gas such as argon, nitrogen, or carbon monoxide. When the alloy contains no sulphur the oxygen may be incorporated into it by mixing the correct proportions of arsenic and antimony before oxidizing the latter. Specifications 865,370 and 866,376 also are referred to.
