Title: A process for the preparation of nitrogen-phosphorie acid compounds
IPC: C23F11/18
Filed: 1957-06-03
Abstract: Phosphorus pentoxide is reacted with an aqueous solution of ammonia to produce nitrogen-phosphoric acid compounds which contain a considerable part of the nitrogen in the form of amino- or imino-groups linked to phosphorus by the nitrogen. NH3 may be simultaneously passed into the solution as the P2O5 is added with stirring and cooling, and such NH3 addition may be continuous to maintain the NH3 content constant.  Alternatively, the P2O5 may be suspended in a solvent immiscible with water, e.g. carbon tetrachloride, chloroform, tri- or tetra-chlorethylene, petrol, or ligroin, for addition to the aqueous solution, and the solvent may be reused.  The compound may be isolated from the reaction mixture by evaporation under vacuum, or precipitated from the aqueous solution by the addition of a watermiscible liquid, e.g. methanol, ethanol or acetone.

Abstract: 809,922. Method of coating fabrics. B.T.R. INDUSTRIES Ltd. and ARNETT, M. Sept. 15, 1955 [June 17, 1954], No.17795/54. Drawings to Specification Class 140. Yarns which form or are to form a fabric are coated or impregnated with a plasticizer whilst still in the loom or knitting machine, which plasticizer is capable of plasticizing a polymeric material to be subsequently applied to the fabric. Preferably such coating is carried out whilst the yarns are still under the tension incidental to the weaving operation, and it is advantageous to coat before weaving in order that the lubricating effect of the plasticizer may be utilized Rot inhibiting agents may be applied to the plasticizer. The yarns may be formed of any suitable materials, e.g. rayon, nylon or " Terylene " (Registered Trade Mark) or even glass. The only plasticizers disclosed are tritolyl phosphate or dioctyl phthalate. The polymeric material to be subsequently applied to the yarns or fabric may be polyvinyl chloride or other vinyl, vinylidene or vinylacetate materials and butadiene acrylonitrile polymer. The process as exemplified is continuous, with stitcher warp yarns being coated with plasticizer prior to linking with the cover warp yarns on their passage through the healds of the loom ; whereafter the fabric, still under some tension, is passed through a bath of polyvinyl chloride paste and led on to rollers. The plastic coating may be gelled in a further operation.

Abstract: 806,139. Umbrellas and walking sticks. KORTENBACH, A., WORRING, H. J., WORRING, D., WORRING, F., and KORTENBACH, K., [trading as KORTENBACH & RAUGH K.-G.]. June 4, 1957 [Oct. 26, 1956; Jan. 10, 1957], No. 17805/57. Class 134 An umbrella frame, of the type having stem members which are telescoped together to open the umbrella, is provided with tension springs 8, Fig. 3, connected between the stretchers 7 and clips 10, which connect the stretchers to ribs 4, and acting to urge the ribs towards the closed position to achieve automatic closing of the umbrella. The two stems 1, 2, Fig. 1, are locked together in the telescoped position by a catch 12 which may be released to close the umbrella by sliding sleeve 17 over stem 2 against the action of a spring 21. In order to use the closed umbrella as a walking stick, a draw rod 22, Fig. 4, is provided in the stems. This rod is formed with an arched portion 25 located adjacent the aperture 24 in stem 2 through which the catch 15 projects when the umbrella is closed. Thus the stems 1 and 2 are prevented from telescoping together when pressure is applied to the tip 5 unless the rod 22 is displaced by moving the sleeve 17 in opposition to the spring 23. The stem 1, Fig. 1, may be provided with two catches, the upper one being used to hold the umbrella open and the lower one to hold it closed, each when in use engaging in an aperture at the upper end of the stem 2. Each catch is released by an elongated form of the sleeve 17 extending to the stretcher ring 6 and separated therefrom by a spring tending to return the sleeve to its initial position. The umbrella may also comprise a third stem 33, Fig. 6, arranged intermediate the stems 1 and 2, so that the umbrella may be long or short when open. The umbrella may be opened either by telescoping all three stems together or by sliding stem 2 over stem 33 until the catch 12 springs into aperture 35 in stem 2.

Patent GB-458684-A (GB)
Title: Improvements in the manufacture and production of conversion products from cellulose or cellulosic materials
IPC: D06P1/649
Filed: 1935-06-21
Abstract: The process described in Specification 259,634, [Class 15 (ii)], for the manufacture of cellulose conversion products is developed by employing for reacting on the cellulosic substance such derivatives of isatoic anhydride as contain at least one aliphatic, cyclo-aliphatic or mixed aliphatic-aromatic radicle with at least eight carbon atoms attached to the benzene nucleus or to the nitrogen atom. As an alternative, the cellulosic substance may be reacted with an isatoic anhydride derivative containing at least one atom or atomic group capable of substitution, and then treated with a reagent capable of introducing the specified radicle. The process is particularly adapted to the treatment of loose or spun textile materials or fabrics of cotton, artificial silk or hemp, or of paper, straw, wood, etc.; and the products which may be coloured or uncoloured, have a wool-like feel, and exhibit water-repelling properties, a fastness to washing, and an affinity for acid dyes. Such derivatives as contain primary amino groups may be diazotized and coupled; or the derivatives, even those containing no primary amino groups, may be reacted with diazo compounds, or alternatively the isatoic anhydride derivatives may contain initially azo radicles. In examples, cotton fabric is treated with N-octodecyl isatoic anhydride in carbon tetrachloride solution, the latter containing sodium ethylate or the fabric being first treated with dilute alcoholic caustic soda. The treated fabric is given a brilliant orange colour by working in a bath of the diazo compound of paranitraniline.

Title: Improvements in processes and machines for rolling raw plate glass
IPC: C03B13/02
Filed: 1930-06-10
Abstract: 353,177. Making plate glass. HILGERS, E., 1, Schorlemerstrasse, Oberkassel, D³sseldorf, Germany. June 10, 1930, No. 17865. Convention date, June 12, 1929. [Class 56.] Rolling.-Relates to a rolling-machine of the kind in which molten glass is delivered into a hopper F, and is formed into a sheet or plate by a pair of rollers a. According to the invention, the side walls 9 of the hopper are tiltable to and from one another in order that the capacity of the hopper may be varied, and in order that the level of the glass in the hopper may be kept constant during the rolling operation. The walls g can be moved by means of toothed segments h which are engaged by driving- pinions i, and the discharge slot through which the glass flows is formed by rollers l arranged at the lower edges of the movable walls. The rollers b form the glass into a plate which is reduced to its final thickness by the rollers a. Plates m close the space between the rollers l, a and are pressed against the rollers by springs n. The plates act as strippers for the rollers l, and also prevent the glass from spreading between the two sets of. rollers. They also minimize distortion of the rollers a by limiting the area of contact between them and the hot glass. When a charge of glass is being rolled, the walls g are moved at such a speed that the level of the glass is kept constant, or is raised, so that the rate of discharge of the glass from the hopper is kept constant. The rollers l may be rotated in either direction to assist or retard the discharge, as required.
