Title: Improvements relating to metallised resistors
IPC: C23F13/02
Filed: 1964-02-24
Abstract: 1,029,324. Resistors. STEATIT-MAGNESIA A.G. Feb. 24, 1964 [Feb. 22, 1963], No. 7590/64. Heading H1S. Metallized resistors are made by an electrodeless metal-plating process by first forming ceramic, e.g. steatite, supports to the required shape, e.g. rods 7 mm. in dia. and 45 mm. long, which are thoroughly cleaned and then pretreated for 2 mins. in an aqueous solution of SnCl 2  (0À1 g./100 c.c.) and for 2 mins. in an aqueous solution of PdCl 2  (0À1 g./100 c.c.) before being further washed in distilled water and placed in a metallizing bath, the composition of which is, for instance, as follows: 30 g./litre of NiCl 2 .6H 2 O, 10 g./litre of NaH 2 PO 2 .H 2 O and 25 g./litre of 70% industrial glycolic acid. The pH value and temperature of the bath are adjusted to give conductive films, which comprise alloys of nickel and phosphorus, having temperature coefficients of between - 50 Î 10<SP>-6</SP>/‹C. and + 150 Î 10<SP>-6</SP>/‹C., the pH value being adjusted within the range 2À0 to 4À5 by means of an alkaline solution, e.g. NaOH. As an example, when supports having the above dimensions are metallized in a bath having a pH value of 2À5 and a temperature of 94‹ C. for 10, 30 and 60 mins., resistors of 70, 15 and 8 ohms respectively, each having a temperature coefficient of - 20 x 10<SP>-6</SP>/‹C., are produced. A reduction in the pH value or the bath temperature reduces the temperature coefficient. Any desired resistance values can be prepared by grinding helices in the conductive films. Longterms stability of the resistors is obtained by tempering for one or more hours at 250‹ C. or less, preferably between 180‹ and 220‹ C., after the resistors have been further washed thoroughly in water and dried. Sodium citrate may be used in place of the glycolic acid, both substances serving to bring about a complex linking of excess free nickel ions. This form of linking operates only temporarily, but it is important since nickel ions which exist for long in the free state tend to cause decomposition of the bath because they serve as accumulation points for further nickel ions.

Title: Retractable lashing or like attachment device
IPC: B64C1/00
Filed: 1953-03-19
Abstract: 725,976. Ground anchors and like devices. BLACKBURN & GENERAL AIRCRAFT, Ltd., and MAYNARD, H. June 24, 1953, [March 19, 1953], No. 7645/53. Class 45. A retractable attachment member is formed integrally with a spring-loaded sleeve axially displacable in the bore of a casing and spring- loaded elements extending through the wall of the sleeve are biased by an externally operable spring-loaded member to engage a groove in the casing to retain the attachment member in its retracted position flush with the end of the casing. The constructions shown are suitable for attachment points in an aircraft or vehicle compartment, and the retracted member lies flush with the surface of the compartment. 'Fig. 1 shows the attachment member which comprises a pair of lugs 1 in the retracted position and Fig. 2 shows the lugs in the extended position. The lugs 1 are integral with the sleeve 3 urged upwardly by a spring 12. Apertures in the wall of the sleeve hold the elements which comprise balls 8 which. engage the groove 7 in the casing 5 when the lugs are extended. The externally operable member 15 is disposed between the lugs and is rigid with a cam member 9 urged upwardly by a spring 10 and controlling the balls. To extend the lugs the member 15 together with the cam member is depressed so that the balls may move inwardly to permit the spring 12 to displace the sleeve and the lugs upwardly. In a modification Figs. 3-5 (not shown), the spring urging the sleeve surrounds the sleeve. In the modification shown in Fig. 6 the wall of the sleeve 43 is provided with radial bores and the elements comprise either balls 48 or slidable members 49 which are acted upon by a spring-urged cam 51 to engage the groove 47 in the casing 45.

Abstract: 1299426 Duplicating machines HEYER Inc 17 Feb 1970 [5 March 1969] 7646/70 Heading B6C A rotary spirit duplicating machine incorporates an electric motor variable drive and a brake band and drum assembly for stopping the machine at the end of a cycle of printing operations. The variable drive is such that as the quantity of hectographic ink on the master appreciably declines the speed of operation may be lowered to maintain a pre-determined quality of print. It may also be necessary to vary the speed of the machine to accommodate sheets of differing characteristics such as weight, flexibility of stiffness. In the machine shown the variable speed control includes belts and a split during sheave 501, Fig. 1, adjustable from a manually actuable control knob 514, and the brake mechanism comprises a solenoid operated brake band 515 and a brake drum 194, Fig. 4.

Patent GB-342931-A (GB)
Title: Process of manufacturing fertilisers
IPC: C05B7/00
Filed: 1930-03-08
Abstract: Microcosmic salt, and a mixture of ammonium and potassium chlorides are obtained by treating a solution of sodium and potassium chlorides, such as may be obtained from sylvinite, with phosphoric acid and ammonia, either in the free state or in combination, in the ratio of one molecule acid and two molecules ammonia to each molecule of sodium chloride.  Microcosmic salt, precipitated, if necessary by cooling, is separated and ammonium and potassium chloride are obtained from the mother liquor.  In an example, phosphoric acid is added to previous mother liquor, and the solution is treated below 50 DEG  C. with ammonia.  The solution is cooled until the separation of the chlorides commences, when microcosmic salt is separated.  Crushed sylvinite is added to the mother liquor, the solution is cooled strongly, and the mixture of ammonium and potassium chlorides ("Potazote") containing, say, 3 per cent of microcosmic salt is separated.  The products may be employed as fertilizers.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of ammonium and potassium chlorides separately by the addition of suitable precipitants, or by fractional crystallization.  The chlorides may be obtained free from microcosmic salt by passing excess of ammonia into the boiling solution to precipitate (NH4)6 Na(PO4)2.  This subject-matter does not appear in the Specification as accepted.ALSO:Microcosmic salt, and a mixture of ammonium and potassium chlorides which may be employed as fertilizer, are obtained by treating a solution of sodium and potassium chlorides, such as may be obtained from sylvinite, with phosphoric acid and ammonia, either in the free state or in combination, in the ratio of one molecule acid and two molecules ammonia to each molecule of sodium chloride.
