Title: Improvements in or relating to process and apparatus for the manufacture of artificial filaments and the like
IPC: D01D5/04
Filed: 1929-09-05
Abstract: 318,630. British Celanese, Ltd., (Assignees of Whitehead, W., and Dreyfus, C.). Sept. 8, 1928, [Convention date]. Apparatus for making filaments and films.-In the manufacture of artificial filaments from solutions of cellulose esters or ethers in particular of cellulose acetate in volatile solvents by the dry spinning method, the filaments are supported in their travel through the evaporative atmosphere so as to prevent the entire weight of the filament from bearing upon the stream of solution flowing from the spinning orifice. The method is particularly applicable to the manufacture of heavy filaments such as bristles, horse-hair, straw, and films. The evaporative atmosphere may be air, nitrogen, carbon dioxide, and may be heated to near the boiling point of the solvent. The roll or band employed as supporting device may be heated if desired. The filaments may be drawn out while drying by passing them over rollers rotating at successively greater peripheral speeds. In the form of apparatus shown in Fig. 1, a heated current of air or other suitable gas may be passed through the casing 1. The spinning solution is extruded through the orifices of the spinneret 2 and is formed into a filament 3 which passes vertically down to the feed roll 4. After passing round the roll 4 the filament 3 passes under guide roll 5 to the draw roll 6, and thence to the winding device 7. In the apparatus shown in Fig. 2, the feed roll 4 is replaced by two rolls 10 and 11 rotting in opposite directions in light contact with each other. and the filament is made to pass between them. In other constructions, the feed. roll 4 may be placed laterally or obliquely with regard to the spinneret, and the filament may be allowed to form n. loop. In Fig. 5, the filament, after passing round the feed roll 40. is made to pass round a series of rolls 41. 42, 43 rotating' at successively greater peripheral speeds, and is thereby drawn out to a finer denier. The Specification as open to inspection under Sect. 91 (3) (a) states that forms of apparatus in which the feed roll is placed obliquely from the spinneret which is placed at an angle to direct the filament towards the feed roll permit of a tensional pull on the filament by the feed roll. This subject-matter does not appear in the Specification as accepted.

Abstract: 802,477. Gas turbine plant. JOHNSTON, J. Oct. 2, 1956 [Oct. 3, 1955], No. 28046/55. Class 110 (3). [Also in Groups XII and XXIX] In a gas turbine plant of the type in which jets of fuel are injected into a mechanically produced stream of air, and in which the fuel ignition is such as to cause successive explosions in the stream, the flow passage ahead of the turbine divides into two branches, one of which passes through a device for preventing back flow and then through a combustion chamber and ends in a nozzle which discharges centrally into the other branch, the passage then continuing as a single straight passage. In the intermittentcombustion gas turbine engine shown, centrifugal compressor blading 6 supplies air through a tangential passage 13 to a combustion chamber 14. Fuel is supplied through an injector 16 and ignited by a plug 17. An aerodynamic valve 15 at the inlet to the flame tube 21 of the combustion chamber opposes back flow during combustion. After leaving the flame tube, the combustion gases are joined, at an injector-like portion 20 of the flow passage, by air which has by-passed the flame tube, and flow tangentially into an annular passage 18. In rotating around the passage 18, the gases acquire a uniform condition free from pulsation before entering inward-flow turbine blading 7. The blading 6, 7 are arranged on opposite sides of a common rotor.

Abstract: 1,171,830. Welding by pressure; making bearings. GENERAL ELECTRIC CO. 19 June, 1967 [1 Aug., 1966], No. 28086/67. Headings B3A, B3Q and B3R. [Also in Divisions C7 and F2] Tin, bismuth, selenium, thallium or other metal is applied to a metal base by placing a body of it on a metal screen over the base and detonating a charge of explosive to melt it and drive it through the screen on to the base, which it wets and forms a layer thereon. Preferably the initial body of coating metal is from 0À010 to 0À025 inch thick and the screen from 0À015 to 0À045 inch thick and the explosive, which may be pentaerythitoltetranitrate (PETN) has the same area as the initial body of coating metal. When the explosive is detonated the surface of the base is deformed by its force and an irregular surface with a layer of the coating metal on it results. A further layer of metal may be emplaced on the irregular, coated surface. For example, a steel bearing shell may have a mesh of copper, aluminium or iron placed over it and tin foil fastened over the edge. Detonation of a sheet of PETN distorts the surface of the steel and coats it with tin. The mesh is then removed and bearing metal is applied to the coated surface by centrifugal casting. A bearing which has become damaged or must be replaced can be retinned by use of the invention, the process being repeated stepwise with some overlap around the inner circumference of the shell.
