Title: Improvements in wire drawing and coiling machine
IPC: B21C1/12
Filed: 1943-12-24
Abstract: 576,734. Stop-motions for winding. DEHN, F. B. (Syncro Machine Co.). Dec. 24, 1943, No. 21659. [Class 120 (ii)] [Also in Group XXII] The winding drum of a wire-drawing or other processing machine is driven through a clutch that is disengaged and a brake applied, when supply to the machine is interrupted by kinking &c. the stoppage causing the using of a bight of wire held by a swinging arm. As the arm moves, a switch closes, stopping the driving motor and shifting the clutch. Wire passes, from a supply, over pulleys 4 to a pulley 5 on an arm 6 on a shaft 7 carrying a weighted arm that tends to maintain the arm 6 as in Fig. 1, a finger 11 holding the switch 13 open. The wire passes at 8 to the drawing or other processing machine emerging at 14 to the winding drum 3. This is on a shaft 26, Fig. 6, bevel-geared to a shaft 23 spur geared to a shaft 18 driven through a plate clutch 30 from a pulley 17 from the motor of the drawing &c. machine. In the event of stoppage of supply the arm 6 at once commences to move and the switch 13 closes exciting the solenoid 83a breaking the motor control circuit at 83<1> and closing at 83<11> the circuit of a solenoid 83, Fig. 4. This pulls down at 105 the end of a bell crank 100 releasing a weighted lever 28 from its other and hooked end and permitting the lever to rotate the .shaft 27 so that its yoke end 271 shifts the clutch sleeve 20 disengaging the clutch and engaging a brake 36. The drum 3 is brought rapidly to rest before the bight of wire carried by the arm 6 is exhausted. Specifications 18034/10 and 221,707, [both in Class 120 (ii)], are referred to.

Title: Improvements in lubricating of leather
IPC: C14C9/02
Filed: 1937-08-07
Abstract: The Specification relates to the use of esters of di- or poly-carboxylic acids in treating leather and describes in example 8 the production of compounds by the diene synthesis by the condensation of maleic, fumaric, acrylic, itaconic, citraconic, crotonic and unsaturated aralkyl acids of the type of cinnamic with substances containing, or developing under the conditions of treatment, conjugated double bonds of the type -C=C-C=C-, such being terpenes, hydrocarbons obtained by cracking, oils such as tung and linseed, dehydrated castor and perilla oils.  For example tung oil and maleic anhydride in molecular proportions are heated to 180 DEG C., the condensation product is esterified with methyl alcohol and used to form an emulsion for the treatment of leather.  The acids obtained by this condensation are stated to be polybasic hydroaromatic acids.  Example 9 describes the production of resins by condensing, (A) diethylene glycol, phthalic anhydride, castor oil and succinic acid; (B) phthalic anhydride, glycerine, linseed oil acids, linseed oil; (C) phthalic anhydride, coconut oil, diethylene glycol; the materials are heated together and the resins neutralized with ammonia. Example 10 describes the preparation of compounds of alkyd resins with fatty acids of oils, e.g. nondrying oils such as tea seed oil.  The monoglyceride of tea seed oil is first prepared by heating the oil with glycerine and sodium carbonate and a polybasic acid such as phthalic or maleic is then added and the heating continued. According to example 11 phthalic glycol resin may be prepared by using glycol instead of glycerine in the process described in example 10.  The Specification as open to inspection under Sect. 91 describes the preparation of a synthetic resin by heating to 230-250 DEG  C. a mixture of 330 parts rosin, 70 parts of glycerol and 45 parts maleic acid, above or in admixture with dibutylphthalate or other suitable plasticizer.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the deposition of copper on non-conducting surfaces
IPC: C03C17/10
Filed: 1919-09-05
Abstract: 152,835. Smith, J. D. Sept. 5, 1919. Coating non-metallic surfaces with metals.- A copper-salt solution is reduced by hydrazine hydrate in the presence of ammonia, the copper being deposited as a coherent coating on heated, non-conducting, smooth or polished surfaces, such as glass, china, porcelain, and the like, in contact with the solution. The coating liquid can be prepared by adding strong copper sulphate solution to a strong solution of hydrazine sufphate in hot water until a faint blue colour persists on standing and a pale-blue powder is precipitated. If not for immediate use, the powder may be filtered and dried. When used, it is suspended in cold water, a few drops of cold hydrazine sulphate solution added, followed slowly by a solution of ammonia until the liquid turns darkbrown, when caustic soda solution is added until a slight yellow or orange precipitate persists after shaking. The precipitate is dissolved by a little hydrazine sulphate, yielding the clear yellowish or brownish liquid required.

Title: Improvements in tennis balls
IPC: A63B39/08
Filed: 1920-07-21
Abstract: 171,741. Spalding & Bros., Ltd., A. G., (Faulkner, F. J., and Whitney, C. B.). July 21, 1920. Balls.-A process of covering tennis balls consists in cementing to the rubber centre a fabric cover the surface area of which is greater than that of the centre and in compacting the cover into a smooth fit upon the centre by the simultaneous action of heat and pressure within a mould. By this process, the cover is applied to the centre without stitches at the seams and to give resilience to the cover. Fig. 1 shows pieces of fabric 2, 3 having markers consisting of notches 4 and ribs 5 to facilitate their proper positioning upon the centre. The pieces of fabric are lightly pressed upon the cemented rubber centre to give the ball the appearance shown in Fig. 3, at which stage it is placed within a mould comprising the jacketed portions 9, 10, Fig. 4, and having steam inlets and outlets 11, 12, and 13, 14 respectively. The mould is of such a size as not to distort the rubber centre of the ball during the compacting of the cover thereon. Before removing the ball from the mould, the latter is cooled by passing water or cold air through the jackets. In a modification, the strips of fabric may be in the form of rectangles with rounded ends.

Abstract: 635,593. Quartz-to-metal seals. GENERAL ELECTRIC CO., Ltd., NELSON, E. H., and POWER, E. B. Aug. 8, 1947, Nos. 21938 and 24097. [Class 36] A conductor 1 is sealed into a quartz body 4 by first passing the conductor through a hole in a metal disc 2 and then embedding the latter in the body. The conductor is brazed or soldered to the disc before or after the latter has been embedded. Both the conductor and the disc may be made of tungsten or molybdenum and the disc may be tapered toward its periphery or may be dish-shaped. The conductor may be formed with an indentation to key it to the quartz when this is collapsed on to the conductor and disc. The conductor and disc may be soldered together with an alloy of molybdenum and nickel which may be produced by placing a ring of each metal round the conductor so that they rest on the disc 2 and heating the rings in a reducing atmosphere till they melt. The method of joining the parts together is shown in Fig. 1 in which 1 is a molybdenum rod passing through an opening in a molybdenum disc 2 and surrounded by molybdenum foil 3. This assembly is inserted in a quartz tube 4 with the disc 2 resting on the top. A pair of semi-cylindrical molybdenum members 5 wrapped in molybdenum foil 6 are placed over the projecting end of the rod 1 and enclosed in a second quartz tube 7 having a flange 9 engaging the upper end of the tube 4. Nitrogen is supplied to the tubes 4, 7 and the edge of the flange 9 sealed to the tube 4. The upper end of tube 7 is then sealed and the whole baked for degassing and simultaneously exhausted through the lower end of tube 4 which is then sealed. The opposed ends of both tubes 4 and 7 are then heated to collapse the quartz on to the disc 2, the tube 7 also collapsing on the members 5. Tube 7 is then cut away and the members 5 withdrawn. A wire of solder is then inserted through the annular space so formed and melts and flows between the disc 2 and rod 1 to form a tight joint on cooling. The lower part of the tube 4 is finally cut off. As shown in Fig. 4 the upper end of the rod 1 may be threaded to receive a metal block 13 and nut 14. A metal tube 15 is soldered to the block 13 and carries a sliding piece 16 for positioning the device of which the seal body forms a part. According to the second Provisional Specification the disc 2 may be made of tantalum. Specifications 201,514, [Class 36], 215,317, [Class 39 (ii)], 513,025 and 563,027 are referred to.
