Title: Process for finishing organic fibrous material
IPC: D06M13/02
Filed: 1974-08-20
Abstract: 1475003 Waterproofed and softened fabrics CIBA GEIGY AG 20 Aug 1974 [22 Aug 1973] 36573/74 Heading DIP An organic fibre fabric is rendered water repellent and given a soft handle by applying to a carrier silicone oil having a viscosity at 25‹C of 1 to 1000 centistokes, bringing the carrier and the fabric in contact and heating to transfer the silicone to the fabric, the fabric having been previously treated with a curing catalyst for the silicone. Part or all of the fabric surface may be thus treated with the silicone. The fabric may be woven, knitted or non- woven, e.g. a needle-felt carpet. Preferably the fibres are cotton, polyethylene terephthalate or blends thereof. Other fibres specified are wool, silk, viscose rayon, cellulose 2¢ acetate, cellulose triacetate, nylon 6, 11 and 66, polyurethane, polypropylene, polyacrylonitrile and poly (1, 4-cyclohexanedimethylol)-terephthalate. The carrier may be a sheet or endless band of paper, aluminium, steel, plastic or glasscloth coated with vinyl resin, polyurethane resin, ethyl cellulose or polytetrafluoroethylene. The silicone oil has the formula: wherein R 1  is C 1  to C 4  alkyl, R 2  and R 3  are independently hydrogen, C 1  to C 4  alkyl optionally substituted with halogen (e.g. 2, 3 dibromopropyl, 2, 3 dichloropropyl and 3, 3, 3 trifluoropropyl), 2-cyanoethyl and phenyl optionally substituted with halogen, methyl or methoxy, and n is 2 to 300. Preferably the oil is dimethyl polysiloxane, methylphenyl polysiloxane, methyl hydrogen polysiloxane, dimethyl methylhydrogen polysiloxane with a hydrogen silane content of 70 to 370 ml/g and a molecular weight of 300 to 5000, methyl-cyanoethyl polysiloxane, methyl-trifluoropropyl polysiloxane or methyl-chlorophenyl polysiloxane. The silicone may be applied direct to the carrier by spraying, pouring or with a doctor blade, or as a 0.1 to 50% by weight solution in an organic solvent with 0.5 to 30% by weight of a binding agent stable at 250‹C. Specified binders are nitrocellulose, cellulose acetate and methyl, ethyl, propyl, isopropyl, benzyl or hydroxyethyl cellulose. The amount of silicone applied is 1 to 100g per m<SP>2</SP> of carrier. The carrier may be dried to remove any solvent, the treated side brought into contact with the fabric and the two layers heated to at least 80‹, preferably 150 to 210‹C for 30 to 120 seconds, optionally with simultaneous pressing. A hot calender or a heated vacuum plate may be used. Preferably the fabric has previously been sprayed coated or impregnated by a solution or emulsion of the curing catalyst or the catalyst has been applied to a carrier and the carrier is heated in contact with the untreated fabric. The catalyst may be an epoxy-amine adduct, zirconium oxychloride, zinc nitrate, zinc chloride, tin chloride, aluminium formate, acetate, chloride or sulphate, titanium isopropoxide, zirconium fatty acid, dibutyl tin dilaurate, dibutyl tin dioctate or tin (II) octoate. 0.03 to 1% of catalyst by weight of fabric may be used. The water repellent finish is resistant to washing at up to 60‹C.

Title: Carbon dioxide absorber for breathing devices
IPC: A62B19/00
Filed: 1966-08-19
Abstract: 1,111,403. Absorbing carbon dioxide. M. W. GOODMAN and T. W. JAMES. 19 Aug., 1966. No. 37199/66. Heading B1L. A carbon dioxide absorbent canister in which resistance to gas flow is maintained low throughout its use includes two foraminous walls 24, 25 which are inclined towards one another and define between them a compartment 14 for carbon dioxide absorbent material (e.g. a barium hydroxide lime compound) across the gas flow path of the canister. Gas passes through the compartment between chambers 27, 28 which communicate with the inlet 30 and the outlet 32, respectively, and each which has a crosssection which increases in a direction away from the inlet and outlet. The arrangement is such that as flow proceeds, maximum gas flow takes place across under parts of the container 14 progressively approaching the widest portion near the inlet and outlet. The outlet may be closed by an expansible bellows (45) so that exhaled air passes through the absorbent material in one direction on exhalation, to the outlet chamber 28 and the bellows (45) and in the opposite direction through the absorbent material to the inlet 30 during the following inhalation.

Abstract: 948,020. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 23, 1962 [Oct. 24, 1961], No. 38069/61. Heading H3P. In a protective arrangement for a pulse generator, pulses representing the current and voltage of the main output are applied to an electronic comparator which is arranged to give an output in the event of a variation from the normal relative values of current and voltage. Fig. 3 shows a pulse generator in which a pulse forming network PFN is charged via inductor 1 and diode D1 and discharged into a load under control of a thyratron S triggered by pulses from a source T. Pulses representing the waveforms of current and voltage in the load are respectively provided by a current transformer and capacitive divider and fed to a comparator C which provides an output only if the voltage/ current ratio is incorrect, e.g. due to flashover in the load. The output from comparator C opens a gate G which cuts off the trigger pulses to the thyratron S or reduces the excitation voltage. Fig. 2 shows a suitable comparator comprising valves V1, V2 arranged as a differential amplifier. The current and voltage pulses are fed in via terminals A, B and capacitive dividers C1 . . . C4. Capacitor C2 is adjusted so that the output is zero under normal conditions. The output of the circuit shown in Fig. 2 may be fed to a counting circuit which provides an inhibiting pulse only after a predetermined number of flashovers. The load in Fig. 3 may consist of a klystron, magnetron or valve oscillator.

Title: Improved process and apparatus for the continuous casting of hollow metallic elements
Inventor: OSTERMEYER GUNTER
IPC: B22D11/08
Filed: 1956-12-14
Abstract: 812,484. Continuous-casting machines. EISENWERKE GELSENKIRCHEN A.G. Dec. 14, 1956, No. 38263/56. Class 83 (1). In the continuous casting of hollow members with a flange or the like at one end, employing an outer chill-mould and a mandrel forming an annular cavity closed at the bottom by a starting component, the casting level during part of the casting operation rises relatively on the outer chill-mould, whilst it is maintained at a predetermined level or normal position on the mandrel. A machine comprises a stationary, conical, water-cooled mandrel 4, a pouring- trough 5 which may be rotated by drive means 7, and a water-cooled outer chill-mould 10 carried by a starting component 13 supported on a downwardly moving table 16. The mould 10 comprises an upper part 11 of normal crosssection, and a lower part 12 corresponding to the flange to be cast. At the commencement of the casting operation, the mould is raised to the position shown in Fig. 1, and when the level of the melt has reached the normal casting level on the mandrel 4, the table 16 is moved downwardly, carrying with it the starting component 13 and the mould 10, until the mould reaches its normal casting position, Fig. 2, where it is halted by a stop 19, while the withdrawal of the casting proceeds normally by continued movement of the cable 16 and the starting component 13. In a modification, Fig. 4, the starting component 27 carries a socket core 29, and is initially raised with the chill-mould 22 so that the core engages the mandrel at or just below the normal level of the melt. During the lowering of the starting component, the core may be extracted before shrinkage of the socket thereon in the manner described in Specification 738,915, which is referred to. In a further modification, the starting component moves first until the thickened part of the casting is clear of the mould, and then the chill-mould is moved with it until it reaches its normal casting position. Alternatively, the chill-mould may be fixed and the mandrel and pouring-trough arranged for upward movement.
