Title: Method and machine for continuous centrifugal casting of hollow shapes
IPC: B22D11/14
Filed: 1971-10-15
Abstract: 1373404 Continuous centrifugal casting; flame cutting L DANIELI 15 Oct 1971 [2 March 1971] 48148/71 Headings B3F and B3V A hollow body is cast continuously and centrifugally in a (copper) mould 8 which is inclined upwardly or downwardly or is horizontal, is cooled (as by a non-rotated water jacket 10), and is oscillated longitudinally, the casting being withdrawn (as by a rotated ring of rollers 33). At the inlet end of the mould 8 is a cemented refractory lining (7) with a diverging bore into which extends a tundish nozzle. The valved tundish may have several nozzles each extending into one of the moulds of a number of parallel casting units. The mould 8, which may have an inner taper towards its outlet, is rotated by a sprocket (11) at the outlet end driven by a chain (23). There may be an inner, perforated, water jacket 9 rotated with the mould and its perforations may be shaped to draw water in at the rear end and pump it back into the jacket 10 at the front. In this case, the horizontal partitions indicated in the jacket 10 in Fig. 1A, are replaced by vertical transverse partitions. There may be impeller blades or fins mounted on or in the jacket 9 or on the mould 8 or a screw-like formation in the jacket or on the mould. The jacket 10 has a sliding guide, or wheels (18) running on a track (19), and is driven back-and-forth by a rod 20 to oscillate the mould structure. Oil or powdered slag lubricant is distributed around inside the mould inlet. In a secondary cooling stand, the rotating cast strand may be supported, on balls 40 or rolls. There may be such supporting-balls at the outlet of a withdrawal unit, which carries at the inlet end of a tubular roll-carrier (31) rotated by the mould-rotating motor (27), a cage 32 of rolls 33 which may be loaded by springs 35, Fig. 1C, with an electric pressure release system, or by a motorized screwdown system or electromagnetic linear actuators. The rolls 33 may be driven at a variable rate from a single motor or individual motors 36. The stand (45) of an oxygen cut-off torch (46) has supporting-balls (44) and is rolled on a track (49) by a mechanical device or hydraulic cylinder (48). The torch is drivable transversely of the casting path. For handling the cut-off lengths and a starter bar (51), there is a stand (52) of rolls (53) of hyperboloid shape oblique to the casting path and driven electromagnetically. A similar stand can be used as a withdrawal unit instead of the ring of rollers 33. The removable head (50) of the rigid tubular starter bar (51) has coarse threading for joining to the cast metal. It is used with asbestos cord packing and scrap metal.  The casting wall thickness is determined by the withdrawal rate, by the pouring rate or by both. The operator controls the pouring, withdrawal and rotation rates by direct observation of the mould cavity, or by periscope, optic fibre, television or from wall-thickness data recorded by X-ray or isotope measuring devices.

Abstract: 1,208,914. Creaseproofing cellulosic materials. CHEMISCHE FABRIK PFERSEE G.m.b.H. 24 Oct., 1967 [25 Oct., 1966], No. 48333/67. Heading DIP. A textile which contains natural and/or regenerated cellulose fibres, is creaseproofed by applying thereto at most 45% based on the dry weight of the textile of a liquor which contains 40-75% by weight of a dimethylol compound of dihydroxyethylene urea or a 4- hydroxy-or 5-hydroxypropylene urea, 0.8- 4.5% by weight of a strong inorganic acid, e.g. hydrochloric, nitric or sulphuric acid, and 20.5-59.2% by weight of water, leaving it to stand e.g. at 10‹ - 35‹C., for 1-24 hours while avoiding loss of moisture, and then rinsing, neutralising and drying it. The liquor may be applied to the textile by padding, spraying or application under pressure or by impregnating a textile web with the liquor squeezing it and winding it together with 1 to 4 untreated webs of the same textile material on a reel and leaving them to stand so that a completely uniform distribution of the liquor absorbed by the one web throughout all the reeled webs then occurs. The textile may be smoothly reeled and enclosed in a polyethylene bag while it is left to stand. Fabrics comprising viscose rayon or cotton optionally in admixture with polyester fibres may be treated.

Title: Production of laminates
Inventor: WILBRAHAM HENRY ARTHUR
IPC: H01R13/621
Filed: 1965-11-16
Abstract: 1,131,718. Reinforced polyester resin laminates. BRITISH INDUSTRIAL PLASTICS Ltd. 10 Nov., 1966 [16 Nov., 1965], No. 48576/65. Heading B5N. A method of making a laminate comprises providing a plurality of flat sheets of cured fibre reinforced polyester resin of which the surfaces that are to be adjacent in the finished laminate are matt, assembling the sheets into a laminate with the matt surfaces facing one another and with a layer of catalysed polyester resin between each adjacent pair of matt surfaces, applying pressure to the laminate so that the sheets are pressed together, removing the pressure before the catalysed resin is cured and curing the resin. The term " polyester resin " is defined as a resin derived from a glycol and a mixture of an alpha-beta ethylenicallyunsaturated dicarboxylic acid, e.g. maleic or fumaric acid, and a saturated dicarboxylic acid, e.g. adipic or phthalic acid. As described the polyester sheets are reinforced with fibres of glass, asbestos, or mineral wool, or with synthetic fibres, and may include substances to reduce flammability, e.g. chlorinated waxes, zinc sulphite, lead sulphite, or antimony trioxide. Alternatively the polyester resin may itself contain chemically combined chlorine. The polyester sheets are preferably of " Filon " (Registered Trade Mark) and may be transparent, translucent, or opaque. In one method described the polyester resin sheet surfaces are matted by sanding, the matt surfaces are coated with catalysed polyester resin e.g. 2 parts " Beltte " (Registered Trade Mark) Resin 4116 and 1 part " Beltte " resin 829, the coated sheets are assembled and passed between pressure rollers, the edges of the laminate produced are clipped together to prevent the entry of air, and the resin is cured in an oven. The laminate may be bent round a former after pressing and whilst the resin cures to form a curved laminate. In a method of making a laminate comprising two fibre-reinforced sheets having one matt face each the matt face of either or both of the sheets may be decorated, e.g. by screen printing with ink and stoving, or by sandwiching a sheet of absorbent printed paper between the two sheets, or by sticking pieces of metal foil to one of the sheets by adhesive, before the sheets are pressed together. In one particular embodiment for making part of a road-sign the matt face of one of a pair of circular fibre-reinforced sheets is printed, dried, coated with a clear alkyd resin solution and redried before coating with the catalysed polyester resin and pressing the sheets together. The laminates formed are weather-resistant and may be used in advertisements. They may include clear and tinted sheets or sheets of different colours.

Abstract: Adipic acid is recovered from the reaction mixture obtained by oxidizing cyclohexane by removing the volatile ingredients by evaporation, and extracting the non-volatile residue with 1,2-dichloroethane to remove impurities and leave substantially pure adipic acid.  The reaction mixture is preferably separated into a polar and non-polar layer and recovering adipic acid from the polar layer by evaporating the volatile ingredients and extracting the non-volatile residue with 1 2-dichloroethane to leave adipic acid. The evaporation may be carried out at up to 120 DEG  C. and at a pressure of from 1 to 200 mm. Hg.  The extraction is carried out at 20 DEG  to 80 DEG  C.
