Title: Process for finishing keratinous fibre containing fabrics
IPC: D06C7/00
Filed: 1964-05-26
Abstract: A durable lustre is imparted to fabrics containing keratinous fibres, e.g. wool, mohair, camelhair, alpaca, cashmere, vicuna, llama or angora wool, alone or in admixture with synthetic or naturally occurring non-keratinous fibres, e.g. polyester fibres, by treating them with a reducing agent capable of splitting the cystine linkages of keratinous fibres, subjecting them to a levelling operation under conditions insufficient to permanently set a substantial proportion of the fibres and then subjecting the levelled fabrics to steam and pressure under conditions sufficient to set the remainder of the keratinous fibres.  The levelling operation may be one involving heat, pressure and time with or without moisture by a pressing operation with fixed presses or a hand iron.  Levelling pressures of 50-50,000 p.s.i. and temperatures of 70 DEG -350 DEG F may be employed.  The steam and pressure treatment may be a full-decatising operation employing a steam interval of 1-10 minutes at a pressure of 1-100 p.s.i. gauge and a vacuum interval of 2-60 minutes.  The reducing agent may be an alkanolamine sulphite containing up to 8 carbon atoms in the alkyl chain, zinc, sodium or potassium formaldehyde sulphoxylate, sodium or potassium borohydrides, bisulphite, sulphite or metabisulphite, ammonium bisulphite, sodium hydrosulphide, sulphide, hypophosphite, thiosulphate or dithionate, titanous chloride, sulphurous acid, thioglycollic acid, sodium, potassium or ammonium thioglycollate, hydrogen sulphide, butyl or ethyl mercaptan or b -mercapto ethanol, and may be applied as aqueous solutions by spraying, padding, squeezing, immersion or wetting with blankets saturated with the reducing solutions.  The reducing agent may be applied in conjunction with a polyhydroxy compound having a molecular weight no greater than 4,000 e.g. glycols having terminal hydroxyl groups separated by 2-10 methylene groups, dipropylene glycol, 1, 3-butylene glycol, diethylene glycol, polyethylene glycol, polypropylene glycol, glycerine, diethylglycerol, trimethylol ethane, trimethylol butane and tris-hydroxymethyl-amino methane, or with other auxiliary agents which may be swelling agents, e.g. quanidine compounds such as the hydrochloride, urea, formamide, N, N-dimethylolformamide, acetamide, N,N-dimethylacetamide, thiourea, phenol and lithuim chloride, bromide and iodide.  After treatment with the reducing agent the fabric may be aged and then dried prior to the levelling operation.

Title: Improvements in and relating to the welding and soldering by means of a beam of charged particles
IPC: H01J37/302
Filed: 1959-06-29
Abstract: 916,869. Discharge apparatus. ZEISSSTIFTUNG, CARL, [trading as ZEISS, C., [Firm of]]. June 29, 1959 [July 1, 1958], No. 22189/59. Class 39 (1). [Also in Groups XXII and XXVIII] In welding or soldering using an electron or ionic beam focused on a workpiece, the beam is interrupted intermittently. The beam pulses are 10<SP>-3</SP> ... 10<SP>-6</SP> secs. long with intervals of at least five times the pulse length. The process is used for seam welding or soldering or for spot welding. Additional material may be fed to the seam during heating or applied on the seam before heating is commenced. In seam welding the beam is deflected from side to side of the seam and in spot welding the beam is moved between pulses so that subsequent pulses fall upon different areas of the workpiece. Usually the work is traversed but of rmaking small welds e.g. on the inside of a tube, the work is fixed and the beam is deflected. In multi-pass welding, the focusing or the amplitude of deflection of the beam is altered for each pass. When welding a closed seam, the duration or frequency of the pulses is decreased as the weld progresses to compensate for heating of the workpiece. Electron beam pulses are emitted from a cathode 5, Fig. 1, on the occurrence of control pulses fed from a source 46 through a transformer 2 to a cylindrical control electrode 6. The beam passes through apertures in an earthed anode 7 and an adjustable diaphragm 8 and passes through an electromagnetic lens 20 and a four-coil deflecting device 23. The workpieces 27 are mounted on cross-slides 29, 30 which are traversed by pulley and cord drives by handles 35, 40 or by a motor 38. Limit switches reverse the motor 38 at the end of the seam. The work-chamber 24 is evacuated by a pump 48. The work is illuminated by light from a source 12 reflected by prisms 13, 14 through apertures 52, 53 in a mirror 16 and a lens 17. The work is viewed through a microscope directed on to the mirror 16. Vacuum locks may be positioned on each side of the chamber 24 to facilitate the insertion and removal of work, which is automatically conveyed from the locks to the chamber 24. In a modification enabling the chamber 24, Fig. 9, to be filled with a protective gas during welding, the space between the deflecting device and the electromagnetic lens 82 is divided into separate compartments 86, 88, 90 each connected to a vacuum pump, so preventing gas leakage from the chamber 24 into the electron discharge device 11. A further arrangement for preventing leakage, consists of a disc 96, Fig. 10, rotating in an evacuated compartment and having a series of axial peripheral passages 101 which pass between apertures 102, 103 traversed by the electron beam. Each passage 101 is aligned with the beam apertures for a time insufficient for gas molecules from aperture 103 to reach aperture 102. The electron beam is switched on only when a passage 101 is in line with the apertures 102, 103. Specification 812,713 is referred to.

Abstract: 748,039. Auxiliary power installations on aircraft. ROLLS-ROYCE, Ltd. July 27, 1954.[Aug. 14, 1953], No. 22521/53. Class 4. [Also in Group XXVI] In a delta-wing aircraft comprising wings 11 and a fuselage 17 and powered by gas turbine engines 10 supplied by air intakes 13, a cooling system for aircraft auxiliaries comprises for each wing a turbine 20 supplied from an intake 18 within an intake 13 with air pressurized by ram effect. The air is cooled by expansion through the turbine and is led by a conduit 24 to engine auxiliaries 15 or to auxiliaries 16 within the fuselage 17, and from the auxiliaries the air is led by a pipe 28 to a centrifugal compressor 29 driven by a shaft 25 from the turbine 20.
