Title: Method of and apparatus for preventing or removing ice formations
Inventor: TAYLOR SIDNEY HERBERT
IPC: B64D15/00
Filed: 1952-03-04
Abstract: 734,772. Removing ice from aircraft. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 28, 1953 [March 4, 1952], No. 5600/52. Drawings to Specification. Class 4. [Also in Groups XIII and XL (c)] The formation of ice on a working surface is prevented, or ice formed on the surface is removed, by feeding on to the surface, or on to or beneath the ice, a gas (such as ammonia) that is soluble both in water and in ice and which when so dissolved is not inimical to the surface, whereby the heat liberated and/or the depression of the melting point of the ice or the freezing point of the water caused when the gas dissolves in the ice or water, inhibits the formation of ice or melts at least a part of the ice already formed on the working surface. A working surface is defined as any surface which it may be desired to keep free of unwanted ice formations in order to permit a device or material of which that surface forms part to perform its normal function, e.g. the surfaces of windscreens (to keep them transparent), of aircraft wings (to permit the desired flow of air thereabout), or of protective covering radomes for radio aerials (to allow the emission or reception of undistorted or unattenuated signals). The working surface may be formed from a porous material through which the water-soluble gas is fed, as in the case of a de-icing and anti-icing cover for a radio lens aerial whose construction is described (see Group XL(c)). The supply of water-soluble gas may be limited to that quantity needed to inhibit the formation of ice by mixing the water-soluble gas with air or other gas or mixture of gases which does not react chemically with the water-soluble gas.

Title: Improvements in or relating to the treatment of wool and wool goods to reduce the tendency to felt and shrink
IPC: D06M11/09
Filed: 1940-03-28
Abstract: 537,671. Treating textiles with liquids. CLAYTON, E., and EDWARDS, W. A. March 28, 1940, No. 5613. [Class 15 (ii)] Wool or wool goods in an unswollen or only slightly swollen and preferably dry state are treated directly with an aqueous liquid containing in solution one or more of the substances, hypochlorous acid, chlorine, and bromine and also an organic acid having reducing properties, e.g. formic or lactic acid. The treatment renders the material resistant to felting and shrinking during wear and washing. The treating solution may also contain a buffering agent consisting of the sodium or other metallic salt of the acid possessing reducing properties, particularly sodium formate, and, if desired, urea, thiourea, or thiodiglycol, which is capable of preventing oxidation of the fibres, and also a wetting agent. The wool or wool goods to be treated may contain natural or artificial hydrophobic compounds, e.g. natural wool grease, textile oil, higher fatty acids obtained from soap or acid soap residues left in the fibres from previous operations or added to the fibres before drying, petroleum oil, or dyes. The material to be treated may be loose wool, wool which has been scoured with non-swelling agents, wool received directly from knitting machines or looms, or worsted which has been passed in sliver form through an aqueous solution of an acid soap such as sodium acid oleate in a back-washing machine, and then dried. Wool goods made from scoured raw wool may be chlorinated or brominated before they are subjected again to the usual alkaline scouring and swelling treatment. If raw unscoured wool is treated it is disinfected at the same time, and it may be scoured after the sulphite treatment which follows chlorination. Preferably, the anti-felting treatment is effected with the liquid at a pH of about 4 which is at or about the isoelectric point of the wool. The acidity may be adjusted during the chlorination by adding an acid of low ionization constant. In an example, tubular knitted wool fabric is immersed in a solution of sodium or calcium hypochlorite containing formic acid and a sulphonated higher fatty acid. The solution is cooled with ice and is maintained at a pH of about 4, a small quantity of formic acid or orthophosphoric acid being added after several minutes of the treatment. The fabric is washed with sodium sulphite or bisulphite solution, rinsed, scoured, and bleached. In another example, botany wool tops are treated with sodium acid oleate solution, dried, and immersed in a hypochlorite solution containing formic acid and thiourea. Raw merino wool is similarly treated. Mixtures of wool with other natural or artificial fibres, or rubber, may be subjected to the treatment.

Abstract: 1,008,813. Rolling. F. MOELLER, and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER U. NEUMANN OFFENE HANDELGESELLSCHAFT]. Feb. 12, 1963 [Feb. 15, 1962], No. 5653/63. Heading B3M. [Also in Division G3] The stressing force in a pre-stressed rolling mill stand is varied by an actuator so that the sum of the rolling force and stressing force is kept constant, the actuator comparing the sum of the forces, as measured, with a preset value and making appropriate corrections. The frames 6 of a rolling mill are pre-stressed hydraulically by piston 4 acting between the chucks 1 of the mill, a device 5 measuring the pressure. During rolling the sum of rolling and pre-stressing pressures is kept constant by a controller 14. The value of total rolling pressure from device 5 is fed via a line 15 to the controller, compared with a pre-set value, and any difference in values is transferred into a movement of a piston 13 to alter the prestressing and make the values agree. The piston 13 by its movement either increases or partially exhausts the pressure in a pressure multiplier 8, the change in pressure being conducted to the pistons 4 to vary the roll pass. Figure 2 shows a measuring device having a number of concentric cylinders 21-25 which are put in either compression or tension and which determines the spring coefficient of the device. A measuring rod 30 is connected to the outer cylinder and to a differential transformer, the output from the transformer is fed to the controller 14

Patent GB-621989-A (GB)
Title: Method of rendering woollen material resistant to shrinking
IPC: D06M11/30
Filed: 1947-02-28
Abstract: Wool or wool goods are rendered resistant to shrinking on subsequent washing and laundering by treating them with an alkaline hypochlorite solution containing 1-6 per cent of available chlorine for a short time of 1 to 60 seconds, and immediately thereafter eliminating the hypochlorite from them. The treatment also has a bleaching effect on undyed materials.  If dyes which are resistant to hypochlorite are used, the anti-shrink treatment may be effected on the dyed materials.  A wetting agent such as a sodium salt of a sulphuric acid ester of a higher secondary alcohol, or a highly sulphonated fatty ester, may be added to the hypochlorite solution.  Preferably, the treatment is carried out at a pH value of 7.5-10.  The temperature may be 0-35 DEG  C.  Wool in the form of raw stock, tops, yarn, woven or knitted fabrics, may be treated.  Cotton, rayon, or other fibres may be present.  The process is preferably carried out in a continuous manner.  The material may be passed through the hypochlorite solution in a padding machine from which it passes through squeeze rollers and then through a bath containing an antichlor.  It is then rinsed in running water.  In an example, a solution containing 3 per cent of available chlorine at pH 8.5 is prepared by dissolving 1 per cent of borax in water, adding commercial sodium hypochlorite solution, adding 0.8 per cent of a wetting agent and adjusting the pH with 2N sulphuric acid. Flannel shirt material is passed through the solution at 20 DEG  C. and thence to squeeze rollers.  It is then passed directly into a 1 per cent sodium bisulphite solution and then rinsed with running water. In another example, calcium hypochlorite is used.  The material may be treated with a solution of a wetting agent before it passes into the hypochlorite solution.

Abstract: 491,226. Interrupters. ELECTROFLO METERS CO., Ltd., and HOATHER, W. H. Feb. 27, 1937, No. 5959. [Class 38 (v)] [Also in Group XXXV] One or more cyclically operable electric switches are adapted to be displaced relatively to a rotary member so that the ratio of the operative and inoperative periods of a switch may be varied and the means effecting the displacement also cause this displacement to occur in the ratio increasing and ratio decreasing directions at rates which may be made to differ by a predetermined and adjustable amount. Fig. 2 shows switches A, B on carriages which are coupled, as by a spring, to move together along a screw turned by a reversible electric motor ; abutments 24 engage the surface of a cylindrical cam 14 driven at a constant and preferably slow speed so that the switches are closed for periods depending on the position of their carriages and open for the remaining period of each cam cycle. An adjustable stop 22 may determine the limit of movement of the switch B along the cam. The alternative circuits of the electric motor include switches C, D, respectively which may be similarly operated by the cam 14 and are adjustable to determine the average speed of the motor in its separate directions. Fig. 1 shows suitable circuit connections for the control of means F<1> controlling heating apparatus in accordance with a temperature sensitive selector operating upon switches E, F. With excessive temperature the switch F is open and contacts d, c are bridged, the motor M then moving in a direction to decrease the ratio of " on " to " off " periods of the switches, and the switches A, B are in series so that the switch B with the shorter " on " periods is in control. Where the temperature is within normal limits the switch F is open and the contacts d, e are bridged so that the motor M is stationary and the switch B is short circuited leaving A in control. Under low temperature conditions the switch F is closed and the contacts d, e are bridged so that the motor M is operative to increase the ratio of " on " to " off " periods of the interrupters, of which A is in control. The switches C, D in the alternative circuits of the motor determine the average speed of the motor in the respective directions. The number of control switches A, B actuated by the cam may be less or more than two and they may comprise mercury switches as indicated, or the rotary member 14 may be a cylindrical drum of partly conducting and partly insulating material with which brushes constituting the controlling switches are adapted to make contact, preferably acting through relays. According to the Provisional Specification the switches controlling the different speeds of the motor may be associated with two worms of different pitches.
