Title: Manufacture of sheet material
IPC: D04H1/593
Filed: 1971-09-08
Abstract: 1365734 Foam coated permeable sheets FELDMUHLE ANLAGEN-UND PRODUKTIONSGESELLSCHAFT mbH 8 Sept 1971 [8 Sept 1970 24 Aug 1971] 41919/71 Heading B2E [Also in Division B5] A process for making a sheet material having a high permeability to water vapour and air and a high water absorbance comprising a pair of non-woven fibrous sheets 21 and 22 joined by a foamed plastics layer 23 is characterised in that a coagulating agent for the foamed plastics is applied in a discontinuous form to the inward facing surface of each sheet and that the foamed plastics is subsequently applied between the fibrous sheets in a form in which it is capable of penetrating the fibrous sheet material, and that the resultant product is coated on each surface, firstly with a foamed synthetic plastics dispersion and secondly with a coagulating agent which is preferably applied discontinuously and the coatings dried. The fibrous sheets may be formed from natural cellulosic fibres, cellulose ester or cellulose ether fibres, polyamide fibres or polyester fibres and preferably contain binding fibres e.g. cellulose coated plastics fibres. The foam of the substrate product may be an acrylic resin, a polyurethane or a natural or synthetic rubber e.g. a butadiene-styrene copolymer or a butadiene-acrylonitrile copolymer. The coagulating agent which may comprise alum or sodium sulphate may be applied by dusting or as liquid spots. In one embodiment, the coagulating agent is a material e.g. ammonium carbonate which also functions as a foaming agent. In another embodiment, the coagulating agent is used together with a foaming agent. When a liquid coagulating agent is used, it may be dried prior to application of the foam. The products of the invention which may be slit through the foam layer, may be roughened and may be used as substitutes for leather. The outer coating may be applied by doctor blade as a dispersion of a composition based on acrylic resin with foam binding agents and thickening agents, and then pulverent Na 2 SO 4  may be applied as coagulent with subsequent drying.

Patent GB-871677-A (GB)
Title: A method of stripping the insulation from the ends of varnished wire windings
Inventor: RAU GUSTAV
IPC: H02G1/12
Filed: 1959-12-12
Abstract: Insulation is removed from the ends of varnished wire windings, such as armature windings of electric motors, by immersing the ends of the winding in a liquid unheated varnish-stripping agent on which is floated a layer of a non-drying oil, e.g. bore oil or mineral oil. The oil prevents the stripper from "creeping" along the wire and removing more insulation than intended.  The stripping agent may be acid, alkaline or neutral, but if the pH p  thereof is outside the limits of 6 to 8 a neutralisation step is necessary.

Abstract: 1,056,880. Folding articles for packaging. KIMBERLY - CLARK CORPORATION. Oct. 29, 1963, No. 42716/63. Heading B8C. [Also in Division D1] In apparatus for folding articles (Figs. 1 and 2, not shown), articles 48 are fed on to supports 42 on a conveyer 18 and transported thereby firstly under a pair of spaced rod-like restraining elements 50 and 52 and then into the path of a pair of folding blades 56, 58 mounted for synchronous rotation in vertical planes on either side of conveyer 18. These blades fold overhanging ends of the articles upwards into U-formation. The articles are then brought into the path of folding blades 74, 76, synchronously rotating in a horizontal plane. These blades fold down the upstanding portions of the articles on to the central portion thereof into a closed C formation. The articles then pass under guard 92 and are transferred from their support means by transfer mechanism 100 to a folding and ejection shoot 102. Here, circumferentially spaced rotating fingers 104 (Fig. 6) force the articles downwards through shoot 102 so as to fold them into pockets 106 of an indexing turret 108 to be individually wrapped during turret movement.

If the cage 1 is to pass straight through the intermediate level, the command signal for the journey energizes the valve 19 to open it to permit the fluid to by pass the unit 6 preventing the deceleration and acceleration in the intermediate level area. In the embodiment of Figs. 2 and 3 (not shown), a common restriction unit in the form of a rotary valve is mechanically controlled by the sensing roller arms at all levels.

Abstract: 1473683 Separating radioisotopes HOECHST AG 3 Oct 1974 [4 Oct 1973] 43030/74 Heading G6R The radioisotope MO-99 is separated from uranium fission products by subjecting a solution of the fission products, with molybdenum in the Mo (IV) state, to one or more of each of the following steps in any order: (a) treating the solution with an adsorbing agent, washing with acid, and eluting the Mo-99 with an alkali; (b) treating the solution with free or combined silver to precipitate silver iodide. The adsorbing agent used in step (a) may be Al 2 O 3 , SiO 2 , ZrO 2  or TiO 2 , the washing acid may be 0À1-5 N HNO 3 , and the eluant a solution of NaOH, KOH, ammonia, or trimethylammonium hydrooxide. In step (b) iodide and iodate may be added to the solution first to convert iodine to iodide, and the solution is then contacted with AgNO 3  solution, freshly-precipitated AgCl, or finely dispersed silver. The solution may be further treated successively with silver nitrate and potassium iodide and then filtered through silver chloride. Such treatment may also precede steps (a) and (b). To form the original solution of fission products, irradiated UO 2  or U/A1 alloy may be dissolved in alkali or acid and treated if necessary with an oxidizing agent, e.g. sodium nitrite, hydrogen peroxide, or chloric acid. The Mo-99 may be supported on a packed column from which high purity technetium-99 m, for use in medicine, is obtained by elution.

In one embodiment, the web passes over an opening guide 14 and a sealing pad 18 to rest on a slotted table 19, the latter being carried on pivoted arms 21, 27 so as to be adjustable heightwise for various article thicknesses. An upper sealing frame comprising bars 40, 42 and a resiliently mounted canvas &c. sheet 53 is pivoted on arms 36, 37 fixed to horizontally slideable rods 43, 50. Also mounted on the rods is a sealing bar 47.

The bars 42, 47 and bar 40 and pad 18 then seal and sever the film about the article. The sheet 53 compresses the latter during sealing. In an alternative form, Fig. 3 (not shown), the web and roll move relative to a fixed longitudinal sealing bar to vary the package width.
