Title: An improvement relating to treating with a liquid, artificial threads, fibres or ribbons made of cellulose
IPC: D01D10/04
Filed: 1928-06-20
Abstract: 318,327. Elling, H. June 20, 1928. Apparatus for making filaments.- Artificial fibres, threads ribbons or the like made of cellulose are treated with liquids for washing or for other purposes. such as desulphurizing, bleaching, wetting, acidifying, oiling, or dyeing, by forcing or sucking the liquids through the material wound on a reel made of a rigid non-perforated porous material or on a reel consisting of a hollow perforated cylinder provided with a non- perforated porous coating, in a direction outwardly from the interior of the reel. Suitable materials for such coatings are, for example, blotting paper, textile fabrics, asbestos, glassfrits, or zeolite. The perforated cylinder must be inert to the liquid used for the treatment, for instance, when the material is being treated with alkali or alkali sulphide, iron, ceramic material, an artificial resin such as a phenol-formaldehyde resin or hardened rubber mav be used or when acids or chlorine are used for the treatment, pure aluminium, an artificial resin, such as a phenolformaldehyde resin, hardened rubber, or ceramic materials may be used. In the apparatus shown in Fig. 1, the cylinder 1 has perforations 2 and a coating 3 of non-perforated porous material on which the spun goods 4 are wound. The reel may be perforated over its entire, surface and the perforations may be of different sizes. The porous coating may cover the outer face of the reel partly or completely but in the former case should cover that part of the reel on which the material is to be wound. In the apparatus shown in Fig. 2, the reel consists of a rigid non-perforated porous material 5, the interior face of which may, if desired, be provided with a glazing 6 from the ends to the line f. The liquids used in the treatments pass through the material outwardly from the interior. The liquid treatments are performed in a very short time without any loss of the liquids. Specification 268,783 is referred to.

Filed: 1939-06-21
Abstract: 530,286. Fuel-injection valves. BOSCH GES., R. June 21, 1939, No. 18033. Convention date, July 20, 1938. [Class 7 (iii)] A fuel-injection valve seating at 6 and opened by fluid pressure is formed with a cylindrical part 14 which, when the valve is first opened, remains within a cylindrical seating so as to permit exit of fuel, the pressure of which, then acting upon the whole seating face of the valve, causes a quick opening to the position shown in Fig. 3, in which the surface 12, provided behind the part 14, produces a divergent conical jet. The bore of the nozzle body is shaped as at 8a, 13 to give a substantially uniform area of flow when the valve is fully open, as shown in Fig. 3. In a modification, the bore in the nozzle body is cylindrical beyond the seating, and the valve is formed with a conical spreader beyond the part 14.

Abstract: 700,032. Treating cereals. STEEL BROS. & CO., Ltd., and HOLL, F. M. May 6, 1952 [July 30, 1951], No. 18039/51. Addition to 563,792. Class 58 In an improvement in or modification of the apparatus described and claimed in the parent Specification, the vessel in which the cereal is steeped and steamed is provided with one or more steam inlets 2, 3 opening into the vessel adjacent a perforated member 6, 5 through which the steam is adapted to percolate into the mass of the cereal. As shown the steam pipe 3 opens into a ring-pipe 4 having a series of apertures circularly arranged to permit the steam to escape and percolate through a perforated baffle plate 5 extending at an angle to the wall of the vessel and shrouding the pipe 4, a perforated frusto-conical baffle 6 being also mounted at a lower end of the vessel such that steam from the pipe 2 enters below it. The provision of baffles prevents an accumulation of cereal on the steam inlet apertures and prevents. these being blocked. The cereal is prevented from coming into contact with steam pipe 4 by the correct arrangement of the slope and depth of the baffle 5.
Patent GB-714385-A (GB)
Title: Purification of acrylonitrile
Filed: 1952-07-18
Abstract: Monomeric acrylonitrile containing as impurities minor amounts of hydrogen cyanide as such or as lactonitrile is purified by treating with from 0.0001-0.5 per cent by weight of an alkali metal or alkaline earth metal oxide, hydroxide, carbonate or cyanide in solution or in solid form.  The treatment may be effected with aqueous base, finely divided solid base or slurried or dispersed solid base in a non-reactive solvent for acrylonitrile such as a hydrocarbon at from room temperature up to the boiling point of the acrylonitrile.  The hydrogen cyanide is converted into a material which is either precipitated or is absorbed on the basic material when the latter is used in solid form.  The basic material is subsequently removed with the impurities by subjecting the treated mixture to distillation, filtration, decantation or centrifugation. In typical examples, a crude acrylonitrile containing 700 p.p.m. hydrogen cyanide and obtained by reacting acetylene with hydrogen cyanide and distilling the resulting product is agitated with (1) 0.125 per cent solid sodium hydroxide pellets and then filtered; (5) with 0.01 per cent sodium carbonate in water and the aqueous layer then removed; (6) with 0.001 per cent calcium hydroxide slurried in kerosene; or (7) 0.01 magnesium carbonate in benzene and the solvent layer then removed; in each case the hydrogen cyanide content is reduced to below 5 p.p.m.  The use of the basic potassium compounds is also mentioned.

A machine for bending tubes comprises a carrier movable over a bed, work-engaging means attached to the carrier for movement therewith and engageable with a workpiece clamped to the bed, means for moving the carrier over the bed so that as the carrier moves the work-engaging means are caused to move along the length of the workpiece, mandrel means for insertion into the workpiece to prevent collapse thereof during bending, and cam means for guiding the carrier to move in a predetermined path over the bed, the construction and arrangement being such that as the carrier moves over its path the workpiece is bent to conform to the shape of the predetermined path. A tube to be bent is held at one end to a machine bed 14 by clamps 62. A carrier 17, mounting two rolls 21, 22 which engage one on each side of the tube, is then pulled along the tube by hydraulic cylinder means 47, a cam follower 28 depending from the carrier 17 engaging a cam track 16 in a plate 15 on the machine bed so that the tube is bent to follow the shape of the cam track. A mandrel 58 on an outrigger frame on the carrier 17 supports the tube internally. The plate 15 has pivot members 41, 42, 43 at the centres of curvature of arcuate parts 32, 34, 36 of the track 16 formed with U-shaped rims 44 engaged by stubs 45 or 46, coaxial with the rolls 21, 22 and depending from the carrier 17, as the carrier 17 moves along the track 16. The carrier 17 thus swings about the pivots 41, 42, 43 to form arcuate bends in the tube, the pivots 41, 42 being automatically retracted after predetermined angular distance has been swung. To form bends in two different planes an indexing member is mounted on the carrier 17 to rotate the tube between successive bends, the clamp 62 being released.
