Inventor: THOMAS ALAN
IPC: H03F9/02
Filed: 1952-02-09
Abstract: 720,197. Magnetic amplifiers. ULTRA, ELECTRIC, Ltd. Oct. 21, 1952 [Feb. 9, 1952], No. 3476/52. Class 40 (4). Magnetic amplifiers 1-3 connected in cascade have positive or negative feed-back proportional to the rate of change of output applied to the first amplifying stage from one of the succeeding stages, the feed-back current being directly induced in an amplifier winding 4 when the D.C. flux varies. A rectifier 7 may be included in the feed-back circuit to render the feed-back effective for changes of D.C. excitation in one direction only. Instead of providing a feed-back winding 5 on the first amplifier stage, the feed-back may be applied directly to the control circuit across a series-connected resistor, Fig. 2 (not shown). The arrangement may also be applied to push-pull amplifiers, the individual feedbacks of the two amplifiers being applied to separate or to common windings on the first amplifying stage. Alternatively the two feed-backs may be combined in a resistance network which injects an E.M.F. into the control circuit.

Title: Improvements in and relating to fabrics made from blends of wool and cellulose acetate staple fibre
IPC: D06M13/52
Filed: 1944-02-25
Abstract: 575,072. Finishing fabrics. COURTAULDS Ltd.. CLULEY, A. S., and ALLEN, T. G. Feb. 25, 1944. No. 3516 [Class 42 (i)] A process for the production of a fabric with a "soft handle" comprises subjecting a moistured fabric containing blends of wool fibres and plasticizer-containing cellulose acetate staple fibres to a milling process. The plasticizer, which may be dimethyl phthalate, tricresyl phosphate, diacetone alcohol &c. may be introduced into the cellulose acetate fibres either before or during the milling process, e.g., it may be added to the solution wherewith the fabric is moistened prior to milling. The plasticizer may be applied in the form of a solution or an emulsion. In an example, a fabric knitted from wool and cellulose acetate staple fibre was impregnated with 40 volumes of a solution containing 20 grams per litre of diacetone alcohol for 30 minutes at room temperature and then squeezed until it contained its own weight of solution. It was then impregnated with a solution containing 50 grams per litre of sodium oleate and again squeezed until it contained its own weight of liquid. It was then milled for 30 minutes at ordinary temperatures. It is stated that the resultant fabric showed considerably more area shrinkage than if the treatment with the plasticizer had not been effected. Specification 356,681, [Group IX], is referred to.

Patent GB-806200-A (GB)
Title: Improved method for the preparation of cold-water-soluble forms of cellulose ethers
IPC: C08B11/20
Filed: 1957-02-06
Abstract: Cellulose ethers in granular form having direct solubility in cold water are prepared by forming a viscous, aqueous solution of a cold-watersoluble cellulose ether containing 2-35 per cent by weight of the ether, gelling the solution in strand form in a hot aqueous bath maintained at a temperature above the syneresis point of the ether and then, while maintaining the ether at a temperature above its syneresis point, rupturing the strand surface, dewatering and drying, and finally comminuting the dried product to a granular form. The cellulose ether solutions used may be obtained from freshly prepared cellulose ethers which have been purified while being formed into a slurry with hot water to extract water-soluble materials therefrom, or by forming a hot aqueous slurry of a commercially obtained fibrous product.  The aqueous cellulose ether solution may be heat-gelled by expressing it into hot water from, for example, a screw-type extruder, the ribbons or rods preferably being cut into short lengths upon extrusion prior to contacting the hot aqueous bath. The strands may be removed from the hot aqueous gelling bath prior to the rupturing operation but it is preferred to combine the two operations and convey the gelled strands through the rupturing apparatus, e.g. a knife mill, in a moving stream or current of the bath.

Abstract: 292,634. Enclosed Motor Co., Ltd., and Mossay, P. A. H. Feb. 15, 1927. Dynamos and motors, cooling; armatures and field magnets, cooling.-In a cooling system for dynamo-electric machines of the kind in which the hot internal air and cold external flow respectively through an outer and an inner series of concentrically arranged ducts c, d running from end to end of the machine, the inner series are formed with apertures e on their inner peri-. pheral walls opening on to the stator laminae b to provide for direct contact of the cooling air with the laminae. As shown, the apertures e are of such a length that the cold air is enabled to sweep over the stator clamping member b<1>, b<2> as well as the laminae. The end shields f, g are formed with axial and radial ports f<1>, g<1> connecting the ducts d with the atmosphere and the ducts c with the interior of the machine. The outer walls of the cold air ducts may be inclined inwards from the two ends so as to cause the air streams to impinge directly on the laminae. Fig. 4 shows a modification in which the air distribution ports are formed in the main stator casting. The ducts c are in communication with the interior of the machine by means of radial ports e<3>, e<3> and the ducts d communicate with the atmosphere by axial ports d<2>, d<3> registering with similar ports in the end shields h. One of the end shields may be formed with a shroud f for the fan which propels the cooling air. In a simplification of this modification the ducts c may be carried through to the ends of the casting and sealed by the end covers h. Fig. 6 shows a modification in which the clamping members k form the inner walls of the cold air ducts. The longitudinal channels are formed by casting a number of radial ribs j along the inner periphery of the stator casting in such a manner that the channels register with porte d<2> in the end shields. Fig. 8 shows a modified air distributing system in which separate rings 0 formed with alternate lateral and radial ports o, o<2> are held between the stator housing a and end shields m. The invention is described more particularly in connection with alternating current motors. Specifications 110,269, 119,505, and 120,241 are referred to.

Filed: 1919-02-20
Abstract: 135,713. Fairbrother, H., (Chemical Construction Co.). Feb. 20, 1919. Potassium salts.-Potassium is recovered as the nitrate from the waste gases of cement kilns and the like by bringing the gases into intimate contact with a solution of a metal nitrate, preferably sodium nitrate.. The potassium and the carbon dioxide in the gases interact with the sodium nitrate to form potassium nitrate and sodium carbonate, hydrosilicates being also produced from the silicates present in the gases. The hydrosilicates are rendered insoluble by heating the solution, leaving the potassium nitrate and sodium carbonate to be separated by crystallization. In the apparatus described, the waste gases from a cement kiln 10, instead of escaping by stack 12, may be conveyed into the tower 15 fitted with baffle plates 18, where they meet a descending stream of sodium nitrate solution, which is pumped up from the tank 19. The falling liquid returns to the tank, whence it can be transferred to the evaporating pan 25, and then, by means of a pump 27, to the filter press 28.
