Title: Improvement in electrolytic tin plates
IPC: C21D9/46
Filed: 1947-07-23
Abstract: 639,788. Making tinplate. TRIGGS, W. W. (Carnegie-Illinois Steel Corporation). July 23 1947, No. 19791. [Class 83 (ii)] [Also in Group XXXVI] Electrolytic tinplate having manufacturing marks on the surface of its steel base is roughened before electroplating to hide the marks and to produce a uniform matt. finish. A strip of tinplate is reduced cold to a thickness of 38 to 21 U.S. Standard gauge and annealed. It is then tempered by rolls which have been uniformly roughened by shot-blasting to produce a matt finish varying in grain size from a maximum insufficient to cause visible light reflection surfaces and to a minimum enough to cause scattering of reflected light to reduce the visibility of the marks. It is then passed through a continuous electro-tinning plant and coated to a thickness of 0.00001 to 0.0001 inch. Printing may be applied directly to the strip without a printing background of enamel &c.

Tools for setting-out work.-A tool for gauging or marking-off the distance between two points or holes, or between a flat surface and a point or hole comprises two beams' pivoted together, the free ends of which carry, in adjustably mounted brackets, a fixed needle and a pivoted needle respectively. Two beams a, b, pivoted together at c, have pivoted to their free ends at d', k brackets d, l<1>. The end of the bracket d is formed to receive the pivot e<1> of a removable needle-holder e carrying a needle f. A pointer g attached to the needle-holder moves over a scale h at the other end of the bracket d. The bracket l<1> carries a removably fixed needle l. The needles f, l as shown are for gauging horizontally, but they may be arranged at right-angles to the positions shown to gauge vertically. Pivoted at k between the bracket l<1> and the beam b is a locking-piece m having an upstanding boss m<1>, the thickness of which is slightly less than the thickness of the bracket. The head of the screw n when tightened clamps the locking-piece m to an extension of the bracket. A projection m<2> of the locking-piece is spring-pressed at p against a ecrew o passing through a lug b<1> on the beam b. The bracket l' when the screw n is slackened is independently moved for a rough adjustment. The screw n is tightened, and a fine adjustment given by the screw o. The edge l<3> is straight, and may be used for gauging from a flat surface. A hole a' is provided whereby the beam a may be clamped to a scribing-block.

Title: Improvements in or relating to mechanism for controlling the feeding of yarns in knitting machines
IPC: D04B15/62
Filed: 1947-07-29
Abstract: 634,237. Knitting-machines. HEMPHILL CO. July 29, 1947, No. 20440. Convention date, April 22, 1940. [Class 74 (ii)] An arcuate guide-member 25 is positioned between the normal binder plate 7 and the needles of a circular machine to guide an elastic or other yarn, fed from an individual feeder 22, below the binder plate, when it is desired to float this yarn, and so prevent it from becoming engaged in the trapping and severing device for the yarns fed from the normal feeders 1. A separate trapping and severing device is provided for the yarn fed from the feeder 22. The trapping and severing device for the feeders 1 is positioned on the binder plate 7 and comprises a member 9, which engages the yarn between its foot-portion 8 and the plate 7, an auxiliary member 11 which lightly holds the yarn when the number 9 is raised to secure another yarn, and a pair of cutters 14 for severing the yarns after they have been secured by the member 9. A notched rod 29 movable in a sleeve 30 positioned above the plate 7, serves to trap and sever the yarn fed from the feeder 22. When a feeder 1 is raised out of action and a fresh one is put into operation, the withdrawn yarn extends from the last needle on which it was knitted to the feeder across its trapping and severing device to be held inoperative. The guide-member 25 is secured to the plate 7 so that its lower edge is level with the lower edge of the plate 7 and the top edge is high enough to prevent the yarn e from the feeder 22, which is floating, from rising above the plate 7 and so being caught in the trapping and severing device for the feeders 1. When it is desired to sever the yarn e, the feeder 22 is raised so that its yarn extends across the top of the guide 25 and above the plate 7, at which height it is kept separate from the yarns in the trapping and severing device of the feeders 1, to be engaged by its severing device 29, 30. A notch 36 is provided in the member 11 to assist in guiding the yarn e into its trapping and severing device 29, 30.

Title: Method of preventing corrosion of submerged iron
IPC: C23F15/00
Filed: 1928-07-13
Abstract: 295,319. Lechler, P., [Firm of]. Aug. 9, 1927, [Convention date]. Corrosion, preventing. - Submerged iron is protected against corrosion by covering the liquid in which it is submerged with a layer of a second liquid lighter than, and insoluble in, the first. For example, iron submerged in water is prevented from rusting by covering the water with a layer of mineral oil, in which bitumen may be dissolved to increase its viscosity. The Specification as open to inspection under Sect. 91 (3) (a) covers broadly the prevention of absorption of gases by liquids by covering the latter with a layer of another liquid of the kind referred to. This subject-matter does not appear in the Specification as accepted.

Abstract: 852,253. Radio transmitting systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 1, 1957 [July 4, 1956; Sept. 28, 1956], No. 20694/57. Class 40(5). A motor-controlled tuning stage is tuned to a required frequency corresponding to that of a pilot signal by applying the latter to a frequency discriminator comprising a variable reactance C1-C6 adjustable in steps and series resistance 3 continuously adjustable by the motor until the voltages across the reactance and resistance are equal, whereupon the motor stops. As shown, the voltages across capacitor C5 and resistance 3, 4 are respectively applied at terminal 6 and between terminals 6, 7 to rectifiers 8 whose differential output is applied to the coils 11, 12 of a polarized relay 9 whose contact 10 engaging terminal 13 or 14 drives tuning motor 16 accordingly. The motor 16 also drives through shaft 17 the variable resistor 3, e.g. a rotary potentiometer without a stop, to a maximum, minimum or other selected value, whereupon a cam 18 on shaft 17 engages closes contacts 22, 22<SP>1</SP> to energize holding windings 23, 24 on the relay and maintains the motor 16 energized while a driving arm 19, also on the shaft 17, engages a movement 21 and drives a shaft 20 and switch arm 2 stepwise to select a different value of capacitor corresponding to a new wave range to be traversed. The opposite end of the arm 19 also has an arcuate projection whereby the movement 21 is locked between switching steps. The cycle is then repeated till the voltages across the selected capacitor C1-C6 and resistance 3, 4 are equal, and the motor then stops and is locked by current through a winding 28 energizing a brake 29. The switches 22, 22<SP>1</SP> may be simultaneously operated as shown or may be pairs of switches angularly arranged at equal distances from the cam 18 and each pair connected in parallel, to increase the angle over which the cam 18 is effective. The differential output of the opposed rectifiers 8 may be applied to one grid of a double triode, the other grid of which is earthed, to derive an amplified reversible polarity output from the anodes applied to the relay coils 11, 12. The discriminator wave ranges may overlap provided the tuning ranges correspondingly overlap.

Abstract: 988,475. Magnetic structures. COMPAGNIE DES FERRITES ELECTRONIQUES. May 30, 1962 [May 30, 1961], No. 20761/62. Heading H1H. Ferrite bodies are formed by mixing powdered metal oxides with a thermoplastic resin binder, forming into shape by injection moulding, and heating to completely eliminate the binder and to sinter the oxides to form the ferrite. The binder may have a weight 5-15% of that of the metal oxides and may be polyethylene, polystyrene polyamides, polyvinyl chloride or mixtures thereof. In one example oxides of nickel, zinc and iron are mixed, presintered at 1050‹ C. and ground. 10-15% by weight of polyethylene dissolved in trichlorethylene and 0À1-2% zinc stearate as a lubricant are added, mixed, and the trichlorethylene removed. The product is injection moulded and heated in an oxidizing atmosphere for 2-6 hours at 180‹ C.-300‹ C. to remove the binder. Subsequent heating at 1200‹ C. sinters the material and it is cooled in O 2  over 10 hours. In a further example MgMn ferrite is formed, a second firing cycle in N 2  or water vapour being performed.
