Title: Improvements in or relating to a spinning assembly for the manufacture of synthetic threads
IPC: D01D4/00
Filed: 1967-04-28
Abstract: 1,116,679. Spinning assembly for synthetic threads. ALGEM ENE KUNSTZIJDE UNIE N.V. 28 April, 1967 [28 April, 1966], No. 19692/67. Heading B5B. In a spinning assembly comprising a housing 1, supply conduit 12, distribution plate 2, and spinneret plate 3, the housing having in at least one of its short sides, a closable rectangular opening 19 through which the spinning plate and distribution plate can be removed, the surface area of the opening being equal to or a little larger than the smallest rectangular side 20 of the distribution plate, and the crosssectional area of the opening being smaller than the surface area of the largest side of the spinneret plate, each opening being closed, on the side away from the distribution plate, by a slidable cover 21 slidably mounted in grooves 22 formed in the housing.

Title: Molding press
IPC: B29C43/00
Filed: 1956-06-26
Abstract: 795,422. Injection-moulding machines. AETNA-STANDARD ENGINEERING CO. June 26, 1956 [July 27, 1955], No. 19736/56. Class 87(2). A press comprises a lower platen 15 carried by a vertically-reciprocable hydraulic ram 12, a tilting head 23 carrying an upper platen 26, and a tilting intermediate press plate 67. The head and plate are tiltable so that parts carried thereby may be visible and accessible. Side clamps 50 releasably secure the head in closed position. The invention is illustrated in connection with a transfer moulding press in which a lower die 17 is mounted on platen 15, an upper die 68 is carried by the intermediate press plate 67, and pressing plungers 28 are carried by the head 23. When the press is closed by raising the ram 12, the plate 67 is lifted and the plungers 28 press rubber stock 93 through passages in die 68 into mould cavities formed in dies 17 and 68. The head 23 is mounted on brackets 24 supported by bearings on a stationary shaft 21 carried by uprights 20. The head 23 carries also a bracket 30 connected to a pin 31 at the end of a piston rod 32 reciprocable by hydraulic cylinder and piston 23. When rod 32 is pulled down, the head tilts. The intermediate press plate 67 is similarly mounted on the shaft 21, being tilted by means of hydraulic cylinder and piston mechanisms. The head and intermediate plate may be held in the tilted positions either by pressure in their hydraulic cylinders, or by latch members 38, 81 (the latter not shown). At the end of the moulding operation, the lower platen 15 and the ram 12 are pulled downwardly by hydraulic cylinder and piston mechanisms 62 acting on arms 61 attached to the platen 15, and the side clamps 50 are turned about their pivots 51, to release the head 23, by the engagement of cams 59 on the arms 61 with rollers 65 on the side clamps. (The clamps are closed for the moulding operation by the engagement of rollers 58 on brackets 60 on the arms 61 with cams 59 on the clamps.) Lowering of the platen 15 separates the die 68 from either the lower die 17 or from the die members 28 on the upper platen. In the first alternative, separation of the two dies results from the fact that the platen 15 can move down further than the plate 67, In the second alternative, fluid pressure cylinders 90 on the upper head 23 actuate piston rods 91 engaging the plate 67, to move the latter away from the upper platen.

Abstract: 900,390. Heating biscuits by electric fields. RADYNE Ltd. June 18, 1959 [June 24, 1958; Aug. 13, 1958; Jan. 5, 1959], Nos. 20225/58, 26039/58 and 388/59. Class 39 (3). In a method of baking biscuits or other flat, thin articles of foodstuffs, the article is heated by heat transfer in a conventional baking oven 10 and then, with the interior of the article still incompletely baked or having a higher moisture content than normal, is transferred to a dielectric heating oven 18 in which the direction of the electric field and the arrangement of the article in the field are such that a substantial component of the electric field passes along the incompletely baked or moist interior of the article. . In the arrangement shown the biscuits pass through the oven 10 on a steel conveyer 12 and are transferred to a fabric belt conveyer 14 which enters and leaves the dielectric heating oven 18 through interference suppression and safety tunnels 16 and 20. The biscuits are then transferred to a cooling conveyer 22. In one electrode arrangement, Fig. 2, the output coil 24 of a generator is connected to a balanced system of two units 26 and 28, each having four parallel rod electrodes 30 arranged above the conveyer belt 14 carrying the biscuits 36. Rod electrodes 32 below the belt are arranged in staggered relationship to the electrodes 30 and are connected through a plate 34 to the frame of the apparatus. Alternative electrode arrangements comprise a system of parallel rods arranged either above or below the conveyer belt and lying either transverse (Fig. 4, not shown) or at a small angle (Fig. 5, not shown) to the direction of movement of the belt, alternate electrodes being connected together to form two sets which are connected to the two terminals of the generator. With these electrode arrangements a single canvas conveyer can be used to pass the biscuits through both ovens 10 and 18. With the conveyer system shown in Fig. 1, conveyer 12 can be run at a higher speed than conveyer 14 thus causing the biscuits to be stacked on end along the conveyer 14 either obliquely or vertically. The electrode system can then be two plates, one above and one below the conveyer 14.

Abstract: Coloured pattern effects are produced on textile materials made of or containing an organic derivative of cellulose by locally applying thereto a paste containing an acid dye, a lower aliphatic alcohol capable of exerting a swelling or softening action upon cellulose acetate, and an inorganic thiocyanate used as a swelling agent for the cellulose derivative, and thereafter washing and drying the materials.  The paste may also contain an aliphatic monocarboxylic acid containing up to four carbon atoms. Specified acid dyes are Xylene milling blue GL, Polar red G, Pontacyl brilliant blue 2R, Sulphonine red B and Guinea green BA. Specified alcohols are methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tert.-butyl, n-amyl, sec.-amyl and tert.-amyl alcohols.  Specified inorganic swelling agents are sodium, potassium and ammonium thiocyanates.  Specified aliphatic acids are acetic, propionic and butyric acids.  The pattern effects obtained are fast to soaping, to light and to acid fading and free from halos, flushing and marking off.  In an example, a cellulose acetate fabric is printed with an aqueous paste containing Xylene milling blue GL, ethyl alcohol, sodium thiocyanate, gum tragacanth and acetic acid and the print is washed, soaped and dried at 110 DEG  C.
