Patent GB-320018-A (GB)
Title: An improved process for dressing textile materials
IPC: D06M13/224
Filed: 1929-09-30
Abstract: 320,018. Oranienburger Chemische Fabrik Akt.-Ges. Sept. 29, 1928, [Convention date]. Grant of Patent refused. Yarns, treating with liquids.-Textile materials particularly silk and artificial silk yarns are treated with a water-soluble or water-miscible preparation of a drying oil such as linseed oil, wood oil, or a varnish made therefrom. The oil or varnish preferably mixed with a siccative is made into an aqueous emulsion with the aid of an emulsifying agent such as soap, sulphonated oil, acetylated sulphonated fatty acid, a condensed sulpho-fatty acid or a salt thereof, a sulphonic acid or sulphonate of an aromatic hydrocarbon, or another colloid material such as a carbohydrate or a protein. In an example, linseed oil varnish is mixed with the fatty acids from coconut oil and the latter emulsified with caustic potash. The mixture is then stirred into a solution of gelatine in water. The resulting product dissolves in water to form a finely dispersed stable emulsion. Skeins of viscoe weft yarn are drawn through the emulsion and are then centrifuged and dried.

Abstract: 774,425. Gas-turbine plant. BLACKBURN & GENERAL AIRCRAFT, Ltd. Oct. 13, 1955 [Oct. 14, 1954], No. 29664/54. Class 110 (3). In a gas-turbine engine, a heat exchanger in which water is converted into steam, is disposed in the exhaust duct, the steam passing to a ring of steam nozzles each ejecting steam between the nozzle guide vanes of the first turbine stage. The engine shown comprises a shaft 1 on which are mounted a centrifugal compressor 2 and two turbine rotor discs 3, 4, an annular combustion chamber 5 being disposed between the compressor and turbine. The exhaust gases pass through the duct 9 in which is disposed a steam generator coil 10, the steam passing to a ring manifold 11 and thence through pipes 12 to nozzles 13 which are mounted between pairs of nozzle guide vanes 6. The steam serves to cool the turbine blades and to increase the mass flow through the turbine. The invention is also applicable to gas-turbine engines of the type having a separate power turbine; also to engines having an axialflow compressor in place of the centrifugal compressor shown; also to engines having a plurality of combustion chambers in place of the single annular chamber shown.

IPC: A01D76/00
Filed: 1951-12-19
Abstract: 712,136. Rakes. BAMFORDS, Ltd. Dec. 8, 1952 (Dec. 19, 1951], No. 29698/51. Class 6 (3) A tractor-drawn hay rake of the type including a draught frame 10 and a tine-carrying frame 14 mounted on a shaft 11 supported by road wheels 12 or by the framework of the tractor, is provided with a hydraulically or pneumatically operated element 17 connected by a pipe or pipes 32 to a hydraulic or pneumatic pump on the tractor, the moving member 19 of the element being arranged to raise the tines 31. As shown, a link 29 connects the frame 14 to a bell-crank lever 27 which is operated by links 21, 22 which are held in alignment near a dead centre position by means of a lug 25 fixed on an extension of the link 21 which engages with the under-side of the link 22. A lug 20 on the link 21 is attached to the moving member 19. The tines are raised when liquid or air is admitted under pressure to the element 17 and the tines fall by gravity to the ground when the pressure in the cylinder 17 is released. The tines may be held in the raised position by the engagement of a catch 36 with an arm 34 mounted on the frame 14. In a modification, the tines may be raised or lowered independently of the hydraulic or pneumatic element by incorporating a lost motion connection in the mounting of the element 17 and providing a lever mechanism which displaces the links 21, 22 and displaces a pawl which engages with road wheel teeth to raise the tine frame in known manner. In a further modification, the element may be double acting so that hydraulic or pneumatic pressure is utilized to lower the tines. The linkage may be arranged so that it moves to a dead centre position to retain the tines in a raised position. Specifications 538,925, 709,447 and 712,110 are referred to.

Filed: 1973-06-22
Abstract: 1424590 Automatic voltage control TOKYO SHIBAURA ELECTRIC CO Ltd 22 June 1973 [23 June 1972] 29842/73 Heading G3R A voltage regulator for a battery-charging  vehicle alternator includes a switching transistor connected in series with the alternator field winding and controlled in dependence on the battery charging voltage. The voltage supplied by auxiliary rectifiers to the field winding is also sensed, and switches the transistor off if a predetermined voltage is exceeded.  As shown, battery 6 is charged over main rectifiers 4, and field winding 3 is energized by way of auxiliary rectifiers 7 and connected in series with a Darlington transistor pair 8, 9. The battery terminal voltage is sensed by a potentiometer 17, 18, and when a Zener diode 14 breaks down, a transistor 12 turns on, so that transistors 8, 9 are switched off. If a break occurs in leads 19 or 33, the alternator is subsequently regulated in accordance with the voltage supplied by auxiliary rectifiers 7 and sensed by potentiometer 31, 23 which is connected to Zener diode 14 by a diode 32. A further transistor may be connected in parallel with transistor 12 and arranged to turn off transistor 9 by earthing its base if the voltage sensed by the potentiometer 17, 18 falls to zero, e.g. due to disconnection of sensing lead 19, Figs. 2-4 (not shown).

Alternatively the tongues h may engage separate hinge pins outside the box. The bottom g when the box is erected rests on iugs l formed either separately from or integrally with the sides and slots m are formed in adjacent sides through which the lugs project when the box is collapsed. Latch bolts n are provided on underside of the bottom which engage slots in the sides to retain the bottom in a lowered position. A lid may be hinged to one of the sides and alternatively the lid and bottom may each be formed in two parts, each part being hinged to an opposite side.

Road-traffic signals on vehicles; semaphore and pointer signals; mechanical telegraphs. - A signalling device for road vehicles comprises a rotary hand-operated member arranged at the front of a vehicle, a rotary signal hand device at the rear, and a flexible shaft for communicating motion between the two. In one arrangement, Fig. 2, the hand-operated member comprises a sleeve e rotatably mounted on a bracket member b and provided with an operating handle f. One end of a flexible shaft g is held in a split cone o by means cf an internallv-coned sleeve n and a nut q.

Means for holding the sleeve e in definite positions comprises inter-engaging V- shaped or like projections on collars i, m., fixed to the rotating sleeve e and the fixed bracket b respectively, these projections being forced into engagement by a spring u. When the flexible shaft is very long, a double-acting spring may be connected between the collar and the sleeve n in order to take up back-lash. The other end of the flexible shaft g is secured by similar coacting conical sleeves 2, 3, Fig. 9, to a disc 4 carrying a signal hand v. Spring-controlled plungers 6 engage recesses 8 in a fixed plate 5 to hold the signal hand in definite positions. The signal device is preferably mounted on an arm 11, Fig. 6, provided with joints 10, 12, 14, having interengaging conical faces so that the signal device is capable of practically universal adjustment. In a modification of the hand-operated device, Fig. 10, the shaft g has its end mounted in a bearing 16 and carries a pinion 18 meshing with a quadrant 19 fixed to a shaft 20.
