Title: Improvements in and relating to Textile Processing
Inventor: CASE JOHN WILLIAM
IPC: D06B9/06
Filed: 1966-09-23
Abstract: 1,170,783. Removing liquid halogenated hydrocarbons from textiles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 Sept., 1967 [23 Sept., 1966], No. 42620/66. Headings D1L and D1P. A volatile liquid halogenated hydrocarbon is removed from a textile material by a continuous process comprising contacting the textile material containing the liquid with steam in a treatment vessel to vaporize the liquid and withdrawing the textile material from the treatment vessel directly into the atmosphere. The organic liquid may have a boiling point not in excess of 125‹C and may be methylene chloride, 1:1:1 trichloroethane, trichloroethylene, perchloroethylene or trichlorotrifluoroethane, the liquid having been used for example to clean the textile material. Fibres, filaments or woven, non-woven or knitted fabrics, including needled or felted webs and carpets, made from cotton, wool, polyester or polyamide fibres may be treated. The steam which may be superheated may be caused to flow counter to the direction of movement of the textile material and the textile material may pass from the steam treatment chamber through a narrow opening into a second chamber filled with steam and from this second chamber through a narrow opening into the atmosphere, the steam trap ensuring a slight escape of pure steam into the atmosphere through the outlet for the textile material. The textile material may be withdrawn through a suitable mechanical seal, e.g. an inflatable seal comprising pneumatic bags coated with polytetrafluoroethylene. The walls of the treatment vessel may be heated and/or lagged to reduce condensation of the steam and solvent vapours. In Fig. 1 fabric 13 is introduced into steam chamber 1 through solvent 4 in leg 2 (in which it may for example be scoured), excess solvent is removed from the fabric by rollers 6, and the fabric is passed over rollers 5 and through outlet duct 14 in leg 3, steam being introduced continuously through jets 7 and 8, the major proportion entering via jet 7, and flowing through the steam chamber and into condenser 10 via duct 9 where the steam and solvent vapour are condensed. Deflection tray 12 is provided to prevent condensed steam and vapours from dripping on to the fabric from the roof of the steam chamber.

Abstract: 971,975. Bakers' ovens. G. & R. GILBERT Ltd. Sept. 4, 1962 [Dec. 5, 1961], No. 43480/61. Heading A2A. In a bakers oven a steam generating vessel 10, e.g. a finned tube, is placed in or near the oven, e.g. in its flue 8, 9, for heating by recuperated or waste heat and delivers a charge of steam to the oven interior through nozzles 22. The generator 10 is supplied with a predetermined amount of pre-heated water from a vessel 11 surrounding the upper part of the flue which in turn is supplied with water from a constant level storage tank 12, filled with a ballcock 13. Burners 7 heat the oven which is preferably of the reel type with trays 5 loaded through a door 6. The flow of water and steam, Fig 2 is controlled by a single control handle 23 which has four operating positions. The first of these allows a charge of water to pass through a valve 14 from the vessel 11 to the steam generator 10; the second closes all outlets to allow generation of steam and a pressure build-up of about 30 p.s.i; the third allows steam to pass through a valve 15 to the nozzle 22; the fourth opens a blow down valve 16 which clears the generator vessel 10 of steam and water residues. A valve 28 reduces the steam pressure to the nozzles to about 5 p.s.i. and by means of adjustable valves 24, 26 a controllable amount of water from the base of the generator 10 may be admitted to the flow of steam. A further venting valve 17 (opened in fourth position) may be provided to supplement the venting path through the valve 15. A safety valve 19 and pressure guage 20 are fitted.

Filed: 1972-09-21
Abstract: 1364388 Pipe couplings; pipe stoppers HYDROTECH INTERNATIONAL Inc 21 Sept 1972 [30 Sept 1971] 43850/72 Headings F2G and F2P In a pipe coupling or pipe stopper arrangement for a tubular member 13, 100, a housing 41, 85 has at least one annular recess 48, 89 supporting sealing means 55, 92 and at least one annular recess 46, 90 supporting locking means 50, 51 and 95, 98, the sealing and locking means forming annular chambers in the recesses which may be pressurized to urge the sealing and locking means against the tubular member. As shown in Fig. 3, one embodiment of the coupling includes two each of the sealing and locking arrangements. An annular testing or bonding chamber 58 is bounded by the seal rings 55 for testing the efficiency of the seals or for receiving a hardenable epoxy resin if a permanent bonded coupling is needed. The annular chambers in the recesses may also receive such hardenable material. The locking means comprises seal rings 50 and grip rings 51. In another coupling embodiment only one each of the sealing and locking arrangements is provided (Figs. 1, 2, not shown).  In one embodiment of a pipe stopper, Fig. 5, the housing 85 includes inner and outer parts 86, 87 each having locking arrangements to be urged by pressure against the tubular member 100. The chambers formed by the locking means are connected by a tube 97 to communicate with the interior of the tubular member 100 so as to be pressurized by fluid therein. The single seal ring 92 is urged by pressure from another source. A pipe 103 and valve 104 may be used to relieve the fluid pressure within the tubular member 100. In another embodiment the outer housing portion 87 is omitted, (Fig. 4, not shown). In other arrangements of the locking means the grip ring may be in two parts with adjacent inclined faces giving a wedging action (Figs. 6, 7, not shown) or a one piece grip ring may have a curved or inclined periphery (Figs. 8-11, not shown) or the grip ring may have a reduced thickness and is located within a split lock ring which is seated inside a seal ring (Fig. 12, not shown).

Title: Automatic dressing apparatus
IPC: A22C25/16
Filed: 1962-11-20
Abstract: 1,027,313. Fluid pressure servomotor systems. V.J.EVICH. Nov.20, 1962, No. 43933/62. Heading G3P. [Also in Division A2] Pneumatic servomotor mechanism 18, for controlling each dressing device in a machine for dressing pieces of fish or meat carried on a travelling conveyer 13 (see Division A2), comprises a cylinder 44 pivoted, at one end 45, to the machine frame 11, and a piston 48 connected to a U-shaped, tubular piston-rod 49, which passes through a cap 50, on the other end of the cylinder, and is pivoted, at 52, to the outer end of the arm 17 of the dressing device, which arm is pivoted, at 20, to the machine frame. The bore through the piston-rod registers with a bore 60 through the piston. The piston is urged towards the cylinder-end 45 by a tensioned spring 53, anchored to the machine frame and to an adjustable threaded bracket 54, carried on a threaded portion 55 of the piston-rod. Compressed air is fed, at constant pressure, into the cylinder, through a manifold 58 and a flexible pipe 59, and passes through the bore 60, the piston-rod 49 and a flexible pipe 65, to a venting valve 66 actuated by a feeler 85 pivoted to the arm 17. When the feeler contacts a piece of meat or fish, the valve 66 vents air at a rate slower than its rate of entry into the cylinder and the piston 48, the piston-rod 49 and arm 17 move away from the conveyer 13, so that the associated rotating dressing roller 27 is brought into engagement with a side or upper surface of the piece. This dressing position is maintained, because the valve 66 then vents air at the same rate as it enters the cylinder. When the dressed piece is moved away from the feeler and dressing roller, the vent of the valve 66 is fully opened and the spring 53 urges the dressing mechanism into its starting position close to the conveyer; actual contact between the feeler and conveyer being prevented by adjusting the bracket 54 so that it abuts the cap 50.

Abstract: 439,832. Gas producers. GES. FUR LINDE'S EISMASCHINEN AKT. - GES., H÷llriegelskreuth, near Munich, Germany. June 16, 1934, No. 17903. Convention date, June 24, 1933. [Classes 55 (i) and 55 (ii)] In the production of a hydrogen-rich, carbon monoxide free gas by gasification of solid fuels with oxygen under pressure and with water vapour to obtain a gas from which the greater part of the carbon monoxide and the hydrocarbons are removed by cooling under pressure, the remaining carbon monoxide and hydrocarbons are removed by washing the gas with liquid nitrogen. The oxygen and nitrogen are obtained as liquids simultaneously in an air separation plant, the oxygen being reduced to a pressure of 10 to 30 atmospheres before it is supplied to the gas producer. The producer gas is preliminarily purified of naphthalene, nitric oxides, gums, tar, carbon dioxide, hydrogen sulphide and acetylene by cooling the gas to room temperature followed by washing with water at the gasifying pressure. Inferior fuels may be gasified and the purified gas is of sufficient pressure for distribution to long distance lines.

Abstract: 1,103,931. Control of A.C. motors. LAURENCE SCOTT & ELECTROMOTORS Ltd. B. J. HILL, D. M. PAYNE, E. C. LARK, and K. K. SCHWARZ. 6 Nov., 1964 [8 Nov., 1963] No. 44207/63. Heading H2J. Forward operation of squirrel cage motor 13 is provided when silicon controlled rectifiers 1A, 1B are rendered conductive by closure of switch 1G. Phase windings 13A, 13B, and current transformer 15 are then energized, whereby voltages derived from control units 11, 12 are used to fire rectifiers 3A, 3B, and energize phase winding 13C. Control units 9, 10 are fed in the blocking direction to prevent conduction of rectifiers 2A, 2B, the blocking potentials charging capacitors 9H, 10H. Rectifiers 1A, 1B, transformer 15, and control units 9-12 are de-energized when switch 1G is opened, the energizing signals on rectifiers 3A, 3B being removed. Rectifiers 2A, 2B are rendered conductive by discharge of capacitors 9H, 10H, so that phase windings 13A, 13B are energized in reverse. Current transformer 14 and control units 5-8 are also energized to block the rectifiers 1A, 1B, and to render the rectifiers 4A, 4B conductive. The motor is therefore braked by reverse-current. During the braking period, capacitors 5H, 6H do not charge sufficiently to energize rectifiers 1A, 1B, at the end of the braking period. The motor is run in the reverse direction by closing switch 2G to render rectifiers 2A, 2B conductive, whereby current transformer 14 and phase windings 13A, 13B are energized. The output from units 7, 8 fires rectifiers 4A, 4B to energized phase winding 13C. Reverse-current braking operation is again introduced when switch 2G is opened. In a remote control system, the silicon controlled rectifiers are rendered conductive by means of two high frequency oscillators which select the direction of rotation of the motor. Unbalance between the potentials of the sliders of two potentiometers energizes one or other of the oscillators, and the motor drives one of the sliders into alignment with the other. Braking is afforded in the manner described except that the control signal is fed to an oscillator instead of directly to the appropriate silicon controlled rectifiers, Fig. 2 (not shown). The motor may be of the twophase type, one motor winding being connected between one supply-phase and neutral, whilst the other motor winding is supplied from the other two lines by way of a transformer. Reversal of the motor is effected by using one or other half of the centre-tapped, secondary winding of the transformer, Fig. 3 (not shown). In a further modification, the motor is supplied from a single-phase source and uses a phasesplitting capacitor, Fig. 4 (not shown). The silicon controlled rectifiers may be replaced by thyratrons or magnetic amplifiers. The current transformers may afford overload protection, the output voltages of the transformers being rectified, smoothed and each applied to a bistable circuit such as a re-set magnetic amplifier.

Abstract: 1477086 Airbag control systems MESSERSCHMITT-BOLKOW-BLOHM GmbH 28 Oct 1975 [16 Nov 1974] 44394/75 Heading G1N A deceleration sensor 7 incorporated in an electronic circuit causes two ignition elements Z1, Z2 to actuate gas generators and inflate an airbag when the vehicle carrying the equipment is involved in a collision. The sensor 7 is a Piezoelectric element producing a deceleration signal voltage which is fed through differential amplifier 6 to a threshold switch 8. The other input to amplifier 6 is an integrating feedback loop R7, C7 connected at P to a reference potential defined by diode D2. When the threshold is exceeded a transistor T7 conducts and fires thyristor T8 to produce current through elements Z1, Z2 directly from battery 1, or by discharge of capacitors C3, C4, when connections to battery 1 are broken. The circuit is prepared when FFT T3 is closed by the battery voltage, after a delay set by components Rl, R2, C5, followed by FFT T4. If the battery voltage is low transistors T3, T4 remain open.
