Patent GB-448215-A (GB)
Title: Manufacture of synthetic resins
IPC: C08G12/08
Filed: 1935-10-04
Abstract: Synthetic resins capable of being moulded are prepared by treating an amine-formaldehyde condensation product containing 2 mols. of combined formaldehyde per 1 mol. of amine obtainable under mild conditions in the absence of acid from a primary aromatic amine and more than two mols. of formaldehyde with an acid condensing agent if desired in the presence of substances capable of combining with formaldehyde such as primary aromatic amines, phenols, acid amides, carbamide, thiocarbamide and aryl sulphonic acid amides and also if desired in the present of solvents both for the starting materials and the resinous products.  When other substances are used additional quantities of formaldehyde may also be employed.  Suitable condensing agents include hydrochloric acid, sulphuric acid, phosphoric acid, acetic acid, salicylic acid, phthalic acid, fumaric acid, maleic acid, acrylic acid, citric acid, tin chloride, zinc chloride, phosphorus trichloride, and boron halides.  The products may be moulded with or without fillers such as woodmeal or the solution may be used in the coating and impregnating of paper web and made up into laminated or rolled bodies.  In examples: (1) a solution of aniline in benzene is dropped into a mixture of benzene, aqueous formaldehyde and aqueous sodium bicarbonate and the separated benzene layer is heated with an alcohol solution of hydrochloric acid of phenol and phthalic acid, or of aniline and phthalic acid to yield a resin solution which may be used for impregnating, varnishing or which may be evaporated to yield a resin; (4) a solution of aninline in benzene is treated with a mixture of aqueous formaldehyde, benzene and sodium bicarbonate and the benzene layer, after concentration, is treated with woodmeal and an alcoholic solution of aniline and phthalic acid with or without the addition of paraformaldehyde to yield a moulding powder. Specification 441,978 is referred to.

Title: Improvements in or relating to ladies' stockings
IPC: D04B9/46
Filed: 1956-09-11
Abstract: 880,516. Knitting. REYMES-COLE, B. T. R. Dec. 11, 1957 [Sept. 11, 1956], No. 27781/56. Class 74 (2). The leg, foot, heel and toe of a stocking are formed by continuous rotary knitting on a circular machine using a thermoplastic yarn such as nylon. The toe end is seamed and cut along line 17, whereafter the heel and toe shaping is obtained by a boarding operation by drawing the closed tube on to a form so as to stretch the heel and toe parts into conformity with the shape of the form. While stretched on the form the stocking is subjected to heat treatment to set it in the shape dictated by the form, which shape it will retain on removal from the form. Some shaping of the heel may also be achieved by occasional part courses being rotationally knitted to form a partially shaped pocket. In the absence of any shaping, however, a small number of part courses, insufficient to produce any noticeable shaping, are knitted by reciprocatory knitting to serve as a guide when boarding the tube on the form. The fabric to form the toe extremity may incorporate a stretch yarn for that part beyond, for example, the line 21 shown in Fig. 3. A course 22 may also be included to act as a marker for the toe extremity from which the most forward part of the seam 17 is to extend. Specifications 756,841, 756,861 and 832,518 are referred to.

Abstract: 633,462. Sole laying presses. BATA, NARODNI PODNIK. Oct. 22, 1947, No. 28220. Convention date, Nov. 16, 1946. [Class 17 (i)] [Also in Group XXIV] In a shoe sole-laying press the fixed head of the machine is adapted to be supported by fluid in a cylinder under control of a valve which is closed for normal operation but in the event of the operator's hand obstructing a guard device this valve is opened to release the said fluid and allow movement of the normally fixed head. As shown the upper mould 3 is carried by a cylinder 4 slidably mounted on a fixed piston 5. Fluid is adapted to be trapped between the piston and the end of the cylinder when a valve 8 is actuated to close by a cam 21 on upward movement of the lower mould 1 on a normal working stroke of the moving head 2 of the press. This fluid provides a solid resistance to movement of the mould 3 against the working impact of the lower mould 1. If however the operator's hand is left between the moulds after starting the machine a guard hoop 29 connected by links 25, 23 to the follower 18 of cam 21 is prevented from moving downwards across the gap between the upper and lower moulds and so maintains the valve 8 open and also moves an abutment 27 on the cylinder 4 into a position to engage a projection 32 on the moving head 2. The moulds 1 and 3 are thus prevented from closing onto the operator's hand and the cylinder 4 is moved upwards by the moving head 2, the fluid escaping past the valve 8. The normal working position of the cylinder 4 is adjustable by a screw 41 acting on a lever 38 to which the cylinder 4 is connected by a rod 36. A spring-loaded safety valve 33 is also provided for the pressure chamber between the piston and cylinder.

[Class 75 (i).] Oxygen supplied through a valved connection 4 to an end body 2 passes through a metering bore 25 and a gradually diverging passage 26 in a tube 13 to a long conduit 29 where it is met by acetylene travelling at about the same velocity supplied through a valved connection 5 on the end body 2 and passing through metering ports 24 in a tubular member 10 to the annular space surrounding the tube 13. The two gases flow along the conduit 29 in coaxial streams until they arrive at the burner tip 41 where they are abruptly baffled to produce turbulence by the end face 44 of a mixing chamber 45. The gases pass from the mixing chamber into the distributing passages of the tip block. The tip block shown is suitable for use in seam welding machines and comprises two multiple jet passages 42 set at an angle to the conduit 29. Alternatively a tip block such as described in Specification 162,431, [Class 75 (i), Burners &c.], having a single distributing passage with one or more series of jet passages may be used. The member 10 screws into the body 2 and engages a head 14 on the tube 13 so that the parts 10, 13 and 2 are held in gas-tight contact at 15, 17. A bush 18 screwing in the body 2 on to a tapered ring 19 renders gastight the joint between the body 2 and member 10. A thimble 28 connects the member 10 with the conduit 29, which is surrounded by a water jacket 35. The tip block may be water-cooled. The Specification as published under Sect. 91 (3) (a) stated that the forward or preheating heating jets of the tip dipscharge a mixture having a slight excess of oxygen and the rearward jets discharge a mixture having a slight excess of acetylene, a speeding-up of the welding operation being thereby effected. This statement does not appear in the Specification as accepted.
