Patent GB-230813-A (GB)
IPC: D01F2/28
Filed: 1925-03-02
Abstract: Threads, films and the like are made from solutions in organic solvents of cellulose esters or ethers or of mixtures of these by employing as a coagulating bath a solution of an easily soluble nitrate such as calcium or ammonium nitrate. The speed of coagulation may be varied by using solutions containing a greater or lesser proportion of the nitrate; or by the addition to the coagulating bath of a solvent such as alcoholic ether or acetone, for the cellulose ester etc.; or by varying the temperature of the coagulating bath. In examples, threads or ribbons are made by projecting solutions of nitrocellulose or of a mixture of methyl cellulose and nitrocellulose or of a mixture of methyl cellulose and acetyl cellulose into concentrated solutions of calcium and ammonium nitrates to which in the last case a proportion of methyl ethyl ketone the solvent for the cellulose derivatives may be added. The process is applicable to the stretch-spinning method; and in working the process the counter-current principle may be employed, and the temperature of the coagulating liquid may vary at different points along its path. The Specification as open to inspection under Sect. 91 (3) (a) includes also the employment of a plurality of coagulating baths of which the first contain solvents in a dilute form, and the later baths consist of concentrated solution of salts such as calcium or ammonium nitrates, ammonium sulphate, common salt, formates, acetates or oxalates; and the earlier baths may contain a proportion of the salts used in the later baths, while these may contain a proportion of the solvent used in the earlier baths; and it includes the following examples:-a solution of nitrocellulose in ether-alcohol is spun into a bath of diluted ethyl or methyl alcohol, and the filaments are then passed into a solution of common salt, sodium acetate, a calcium nitrate; a solution of methyl cellulose and nitrocellulose is allowed to flow through a slot-shaped aperture into a mixture of acetone and carbon tetrachloride, and the spun material then treated with a concentrated solution of ammonium nitrate; a solution of methyl cellulose and acetyl cellulose in methyl ethyl ketone is first passed into a mixture of acetone and water, then into a solution of calcium or ammonium nitrate containing methyl ethyl ketone, and finally into pure salt solution. This subject-matter does not appear in the Specification as accepted.

Filed: 1956-02-24
Abstract: 783,757. Ventilating vehicles. DAIMLERBENZ AKT.-GES. Feb. 24, 1956 [Feb. 25, 1955], No. 5865/56. Class 137 [Also in Group XXXVII]  The air flow into a ventilating duct due to forward motion of a vehicle is supplemented by an electric fan, control means, responsive to thrust pressure or vehicle speed, being provided for varying the speed of the fan from a maximum when the thrust pressure or vehicle speed is zero, to zero when the thrust pressure or speed increases to a maximum. If the vehicle speed or thrust pressure rises unduly, the fan may be reversed. An inlet duct 2, 3, leading to the interior 5 of the vehicle, is provided with a fan 1, driven by an electric motor 6, and may enclose a heat exchanger 4. The fan motor 6 is controlled by a manual switch 28 and a speed-regulating and reversing switch 11 which has two resistances 23, 25 separated at 24. The rheostat arm 10 moves with, but is insulated from, an arm 17 which sweeps over two sets of contacts 18, 19 and 26, 27 connected with the motor terminals 8 and 7 respectively, the arrangement being such that as the arm 10 is swung counterclockwise the motor speed falls from a maximum when the arm is in contact with the stop 13, to zero when the arm is in the neutral position 24. Further movement of the arm 10 produces reverse rotation of the motor at a speed rising to half its maximum speed in forward running when the stop 14 is reached. The arm 10 is positioned by means controlled by the thrust pressure, or by a centrifugal governor. In another embodiment, the fan has a constant direction motor, controlled by a rheostat arm which is moved, as the car speed increases, to slow up, and eventually to stop, the fan. The rheostat arm is connected, through a lost-motion device, to a valve pivoted in the air duct so that further increase in the car speed moves the valve to restrict, and ultimately to close, the duct.

Patent GB-452591-A (GB)
Title: Improvements in or relating to the separation of materials of different specific gravities
IPC: B03B5/38
Filed: 1935-02-26
Abstract: 452,591. Washing granular materials. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WOOD, H. L., c/o Fraser & Chalmers. Erith, Kent. Feb. 26, 1935, No. 6138. [Class 82 (ii)] In a method of separating light and heavy constituents of a mixture by immersion in a fluid mass of intermediate specific gravity composed of a liquid, e.g. water, and comminuted solid, e.g. sand, so that the heavy constituents sink and the light are carried over a weir by the fluid mass, small particles of the'mixture to be separated are introduced into the fluid mass below the surface thereof together with a quantity of the liquid, e.g. water, which is one of the components of the fluid mass. The fluid mass is thus diluted at the point of introduction and the light constituents are caused to sink to such a depth that they have to rise to pass over the weir. Larger particles of the mixture are preferably fed on to the surface of the liquid. In the apparatus shown in Fig. 4, the fluid mass and a supernatant layer 10 of water are contained in a vessel 1 which has an overflow weir 3. Small particles of the mixture, e.g. coal, to be separated are fed into the mass by a shoot 5 leading to an aperture 2 controlled by an adjustable gate 4, the material being washed through the aperture by jets of water from a pipe 7, the water serving to dilute the mass adjacent the aperture 2. Larger particles of the mixture are fed bv a shoot 8 on to the surface of the liquid. Fig. 1 shows an apparatus in which the fluid mass is agitated by rotating stirrers, the particles from the shoot 5 being carried round in an annular path to the weir 3. Fluid mass to replace that carried out with the separated constituents is introduced by the shoot 13, which is removed from the feed aperture so as not to interfere with the dilution. Specifications 119,038, [Class 82 (ii)], and 415,881 are referred to.
