Title: A new or improved process for the extraction or treatment of vegetable fibres
IPC: D01C1/02
Filed: 1930-09-12
Abstract: 363,651. Retting. GRATZE, E. V. HAYES-, 41, Fitz George Avenue, Kensing- ton, London. Sept. 12, 1930, No. 27249. [Class 120 (i).] Vegetable fibres are extracted or treated by means of a reagent, or aqueous solution thereof, prepared by treating a neutralized sulphonated oil to an electric ionization process either by electrolysis or by the action of high tension or high-frequency discharge, or by a combination of both. The process is best suited for the treatment of New Zealand hemp, Pita hemp and Pita grass, but is also applicable to flax and cotton. Any suitable oil may be employed, either vegetable, mineral, animal, or fish, but preferably vegetable such as castor or olive oil. The castor oil is sulphonated, neutralized and then ionized by electrolysis and high-frequency discharge so that on dilution with 10 volumes of water the solution has a pH value of not less than 7, and preferably between 7À5 and 8. The ionized oil is diluted with 25 volumes of water and heated to 50-110‹ C. 1-5 per cent of a bleaching agent such as hydrogen peroxide, sodium hypochlorite, sulphur dioxide, sodium peroxide, sodium bisulphite or sodium hyposulphite may be added. The leaves or stems of the plant to be treated are preferably subjected to a preliminary mechanical treatment such as scraping or perforating the outer skin; during or after such treatment the ionized oil is employed, which softens the surplus vegetable material, so allowing it to be removed by pressure. The fibres are then bleached if no bleaching agent has been added to the bath, and the product graded combed, and spun. Specifications 363,652 and 363,653, [both in Group III], are referred to.

Title: Electronic pulse generating apparatus
IPC: H03K3/26
Filed: 1957-08-30
Abstract: 863,621. Transistor monostable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 30, 1957 [Sept. 4, 1956(2)], No. 27372/57 Class 40(6) In a circuit comprising two transistors 10, 1<SP>1</SP> of the same conductivity type, the emitters are coupled together and to a first potential with coupling between the collector of transistor 10 and the base of transistor 11, these electrodes being connected to a different potential. An input signal applied to the base of transistor 10 changes its state to generate an output signal, the circuit restoring after a predetermined time. Assuming diode 12 and transistor 10 to be conducting, the collector potential is held sufficiently positive to bias off transistor 11 at the base, the emitter being held near earth potential due to diode 59 conducting. Due to the use of the potential divider 16, 17 the emitter of transistor 10 is held sufficiently positive to ensure its conduction. A positive going input signal applied over capacitor 15 drives the base positive and the transistor 10 cuts off. The resulting fall in collector potential lowers the base potential of transistor 11 so that it passes to the conducting state. The fall in emitter potential is transmitted through the divider 16, 17 and associated capacitor 20 to lower the emitter potential of transistor 10 and hold it cut off. The fall in emitter potential of transistor 11 is fed to the base of normally cut-off transistor 54 which conducts to provide a positive-going output pulse. The output pulse is fed back over inductor 57 which causes a delay, to drive the base of transistor 11 positive so that it cuts off and the circuit is restored to its initial condition.

Abstract: 683,896. Check draught dampers and explosion fittings for stoves. LANGHAM, A. J. Oct. 25, 1950 [Oct. 25, 1949], No. 27389/49. Class 126 [Also in Group XII] An automatic draught stabilizer for the flues of furnaces, boilers or stoves of the kind in which a counterbalanced valve is pivotally mounted within an opening leading to the flue comprises a frame 1 set in the wall 3 of the flue and the counterbalanced valve 5 so constructed and mounted in the frame that it will open readily either inwardly or outwardly under the influence of a depression or of a positive pressure in the flue as disclosed disclosed in Specification 683,892. The valve 5 comprises an aluminium or like sheet formed with reinforcing side flanges 6 and transverse flutes 8 mounted asymmetrically on a rod or tube 10 pivotally carried by the frame 1 and formed also with a central oblong slot 14 for the passage of a weight and lever assembly. This assembly comprises a bar 11 secured to a segment 13 clamped to the rod 10 having a lower arm disposed inwardly of the valve and carrying weights 22, and an upper arm 15 disposed outwardly of the valve and fitted with a rubber stop 15<SP>1</SP>, cushioning contact of said arm with said valve and! with said frame. When the valve moves inwardly under the influence of a depression in the flue, Fig. 2, the bar 11 is carried with it, but when the valve moves outwardly under the influence of a positive pressure, e.g. an explosion in the flue, Fig. 3, the bar 15 is held against the frame 1 by the stop 15<SP>1</SP> and the valve moves freely. The bar 15 may be locked by a spring or other catch 60 and a counterbalancing weight in the form of a bar 9 is secured to the upper part of the valve, reducing the pendulum-wise movement of the valve. Each end of the rod or tube 10, Fig. 7, is provided with a ball 23 urged axially outwardly by a spring 24 in sockets 25 having ends spun over to be of slightly less diameter than the balls, which seat again screw-threaded members 26 passing through the frame and being provided with lock-nuts 27.

Abstract: A solution in xylol of calcium naphthenate is obtained by agitating a milk of calcium sulphate in water with xylol, and agitating the mixture with a water solution of potassium naphthenate.  The potassium sulphate formed is removed by solution in the water present.  A solution of barium naphthenate in mineral spirit is obtained similarly by agitating a water suspension of barium hydroxide with a solution of naphthenic acid in mineral spirit.ALSO:<PICT:0426643/III/1> Solutions in organic solvents of water-insoluble naphthenates, linoleates, or abietates adapted for use as driers in the paint industry are obtained by reacting the free acid or an alkali salt thereof and the metal salt or hydroxide used in the presence of water and the organic solvent, the water and solvent being immiscible but intimately admixed during the reaction. After reaction the organic salt desired remains in solution in the organic solvent and the byproduct if not water is removed by solution in the water present.  The solid salts may be obtained by evaporating the organic solvent.  Solvents specified for use are mineral spirits, xylol, and pine oil, but more volatile solvents may be employed. Both components of the reaction may be used in solution in water, or one may be dissolved in water and the other in the organic solvent.

In a press, a pressure member 4, joined by springs 14 to a second member 7, is reciprocated along guide columns 2 towards and away from press table 1 in a step-by-step manner. Each of the members 4 and 8 may be clamped in position on columns 2 by introducing fluid under pressure between outer rigid sleeves 10, carried by the members and inner deformable sleeves 9, of e.g. rubber, which surround the columns. In the preferred embodiment member 7 carries a piston and cylinder device 5, 6, 8 the piston-rod 5 of which is connected to member 4. In operation the upper member is clamped to the columns and the piston and cylinder mechanism is actuated to drive member 4 downwards until stop 11a carried by member 4, actuates a changeover switch 13 carried by member 7. This deactuates the piston and cylinder mechanism, releases member 7, and clamps member 4 thus causing the upper member 7 to move downward under the action of gravity and springs 14 until switch 13 abuts stop 11b. Switch 13 is thus re-actuated to release member 4, clamp member 7, and operate piston and cylinder 5, 6 8 once again thus moving pressure member 4 downwards by a further step to further compress the workpiece. In alternative embodiments the members may be clamped by means of brake-bands or by pins carried by the members which releasably engage holes in the guide columns. In a further embodiment the piston and cylinder mechanism may be replaced by an inflatable bladder interposed between the two members.
