Patent GB-604644-A (GB)
Title: Improvements in or relating to the metallising of non-metallic bodies
IPC: C23C18/34
Filed: 1945-11-29
Abstract: In a method of coating a non-metallic body with a metal, the body is immersed in a solution containing a salt of nickel or cobalt or a salt of each of these metals, a hypophosphite and a hydrazine compound.  A noble metal in colloidal suspension may be present as a catalyst.  In an example a vessel containing 10 parts of a 1 per cent nickel acetate solution and one part each of a salinated solution of sodium hypophosphite and an 85 per cent solution of hydrazine hydrate has two drops of a 0.1 per cent solution of palladium chloride added as a catalyst; intensive reaction at room temperature results in an opaque nickel mirror being deposited on the walls of the vessel.  The presence of ions of a hydroxy acid other than tartaric acid or a keto acid is beneficial and phosphide deposits may be avoided by the addition of an organic nitrogen base having at least one C-N bond. Wetting agents may also be added.  The temperature of the solution may be maintained below 20 DEG C. during deposition.  The deposit may have other materials deposited electrolytically, e.g. copper, silver or gold, and it may also be readily coated with molten tin or solder.

Title: Improvements in or relating to the production of composite yarns
IPC: D02G3/24
Filed: 1936-11-26
Abstract: 474,413. Yarns. BELL, A. S. Nov. 26, 1936, No. 32336. [Class 120 (iii)] A composite yarn is formed by doubling together a crimped and an uncrimped yarn in one direction and then doubling the doubled yarn with one or more similar doubled yarns in the reverse direction. Each uncrimped component yarn may be twisted in the direction opposite to the direction of its doubling twist but to a lesser extent and at least one of such yarns may comprise two or more uncrimped yarns twisted together, in a direction opposite to that of the doubling twist. The crimped component may be of a greater denier than the uncrimped component and may be of greater length so that it spirals around the uncrimped component while the yarns are being doubled together. The components of the composite yarn may be of like or of different materials and of a fibrous or continuous character, e.g. a cellulose acetate yarn may be formed from crimped or uncrimped yarns of continuous filaments and the yarns may have different characteristics, e.g. of lustre, colour or saponification, and may have been stretched to impart a high tenacity thereto. The crimp may be imparted to the filament or fibres by rollers and may be set by steam, or by twisting, setting and untwisting the yarn as a whole, by treatment with hot aqueous liquors in the case of cellulose acetate and similar substances, e.g. as described in Specification 459,781, or by any combination of these processes and the crimp may be fixed by the process described in Specification 455,021. A crimped cellulose acetate yarn may be produced by the processes described in Specifications 424,880, 442,073 ; and 464,981, [Group II]. Specifications 474,401 and 474,402 also are referred to.

Title: Improvements in or relating to electric oscillation generators
IPC: H03B5/34
Filed: 1955-11-11
Abstract: 818,774. Valve oscillator circuits. SANGAMO WESTON Ltd. Nov. 11, 1955 [Dec. 2, 1954], No. 32336/55. Class 40 (6). A crystal-controlled oscillator and harmonic generator comprises a triode valve with a crystal connected in its grid circuit, a non-linear inductor 12 connected to its anode to cause the circuit to oscillate at the crystal frequency and a parallel resistance-capacitance circuit 14, 15 in the cathode circuit to improve the harmonic content in the output circuit. The non-linear inductor changes its value as the valve current changes during the oscillation cycle and this increases the harmonic content of the output signal and by changing the resonant frequency of the inductor reduces the drive on the crystal. Specification 817,821, [Group XXXVI], is referred to.
Patent GB-726886-A (GB)
Title: Improvements in and relating to x-ray goniometer apparatus
IPC: G01N23/20
Filed: 1953-11-23
Abstract: 726,886. X-ray apparatus. GENERAL ELECTRIC CO. Nov. 23, 1953 [Nov. 22, 1952], No. 32450/53. Class 98 (1). [Also in Group XL (b)] An X-ray goniometer for determining the orientation of crystals in a specimen (for example an alloy), comprises an X-ray source, a specimen holder, means for translating into electric signals and recording X-rays diffracted by the specimen, and means for progressively rotating the holder about its axis and for linearly reciprocating the holder, the two movements being coupled. As shown, X-rays from a source 4 are diffracted by the specimen mounted in a circular holder 2 and detected by a Geiger counter tube 5 which through an amplifier 7 operates a recording pen 8. This pen marks a sheet 10 driven at constant speed and synchronized with the rotation of a gear 20. Gear 20 drives a cam and follower 16 which reciprocate a member 12 which carries with a shaft 13 which in turn reciprocates the specimen holder across the X-ray beam. As the shaft is lowered a stud 25 engages a fixed plate 26, thereby rotating a ratchet wheel 24, to rotate the specimen holder about its own axis. Thus the specimen holder is given both a reciprocating and a rotational motion. The holder may also be rotated intermittently about a vertical axis. This is accomplished by contacts 46, 47 on the edge of the specimen holder which bridge fixed contacts 32 when the specimen holder is in one of a number of fixed positions. A solenoid 36 is then energized to move a ratchet 40 which, on subsequent de-energization of the solenoid, steps around shafts 13 and 14. Simultaneously a marker 49 places an indication on the recording strip that the specimen has been rotated. A recess may be provided into which contacts 46 and 47 may be retracted, and thus made inoperative.
