Patent GB-674086-A (GB)
Abstract: 674,086. Thermally-actuated valves. SUGG & CO., Ltd., W., and SUGG, B. R. Aug. 10, 1949, No. 20847/49. Class 135. A safety cut-off gas valve controlled by a bimetallic element and a pilot jet is arranged so that when the jet is extinguished and the element cold a clearance is provided between the element and the valve operating spindle. As shown, a casing 1, Fig. 1, having an inlet 9 and an outlet 6 houses a valve member 3 urged by a spring 15 towards its seat 4 and movable therefrom by the engagement of a bimetallic element 29 with a valve operating spindle 16 on the lighting of a pilot jet 14. The clearance between the spindle and the element may be gauged to ascertain whether there is any weakening of the element 29 through fatigue. In a modification, an overheat safety mechanism is fitted comprising a bimetallic element 20, Fig. 3, having a depending limb engaging a spring-loaded cap 21. In the event of overheating, the element 20 is deflected away from the cap 21 which is urged downwards by its spring and, through a nut 23 and spindle 28, the valve 3 is closed on to a lower seating 25 to cut off the supply of gas to the burner. Lost motion is provided between the nut 23 and the cap 21 to permit the valve 3 and seat 4 to co-operate with each other at normal operating temperatures. Specification 674,048 is referred to.

Patent GB-729518-A (GB)
Abstract: 729,518. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Feb. 13, 1953 [Feb. 29, 1952], No. 4152/53. Class 97 (3). A gyroscopic instrument having an electrically spun rotor universally mounted about two mutually perpendicular axes, includes a brake adapted to limit or prevent oscillations of the rotor about one axis, said brake being rendered operative on de-energization of an auxiliary electric motor and rendered inoperative on energization thereof, and said auxiliary electric motor having at least one winding in series with a winding of the rotor spinning motor, whereby the brake will be rendered operative whenever the latter motor is deenergized. In the gyro horizon shown, the rotor 9 rotates about a vertical axis in a case 11 which is journalled about an axis in a gimbal 13 rotatable about a perpendicular axis, a horizon bar 17 being visible in a window 19. The rotor may be centred and caged by a device comprising cams 27, 29 as described in Specification 701,385, the cam 27 also cooperating with a brake 47 carried by a pivoted sector gear 37. This gear is movable into engagement with a stop when a motor 31, having windings 69, 71 in series with the windings 61, 63 of the rotor motor 7, Fig. 3, is energized; and, on de-energization, the gear is moved into contact with another stop 39 by a coil spring 43. Movement into contact with stop 39 causes the brake 47 to be moved to its active position where it engages cam 27 when the gimbal oscillates through +45 degrees from centred position and prevents further gimbal oscillation. At the same time a flag indicator 49 as in Specification 686,818, [Group XXXVII], carried by a rod linked by a pin-and-slot connection to gear 37, becomes visible in the window to warn of a power failure. Reference has been directed by the Comptroller to Specification 625,415.

Title: Process allowing the delignification and the transformation into sugar of lignocellulose vegetal materials by using organic solvents
IPC: D21C3/20
Filed: 1978-08-31
Abstract: Minced lignocellulose, such as wood, straw, bamboos, bagasse or any other structured vegetal material, is treated in a discontinuous or continuous process. The process consists in boiling this material in an acidified mixture of solvents in an aqueous phase. This mixture of solvents contains water in a proportion of 30 to 70 parts and an organic solvent in a proportion of 70 to 30 parts. The organic solvent consists of either an alcohol of light molecular weight, or a ketone of light molecular weight; it must be easily evaporable and soluble in water. The pH of the medium is adjusted to a pH from 3.5 to 1.7 by adding a catalytic compound selected within the group of the strong acids: hydrochloric, nitric and phosphoric; within the group of these strong acids neutralized by their neutral salts; within the group of the following organic acids: oxalic, maleic, o-phthalic, l-malic, succinic, nicotinic, salicylic and trifluoracetic. The boiling temperatures range between 160 and 210`C, preferably between 180 and 200`C. After three minutes at the minimum, we obtain the separation of the lignin and the hydrolysis of the hemicelluloses dissolved; after that, the fibres are easily dispersible while forming a pulp. By proceeding to a mechanical refining at a high pressure, a high density thermomechanical pulp is obtained after a shorter boiling time. With the neutralized acids, as well as with the organic acids, particularly with the oxalic acid, we can obtain a fibre with a high degree of polymerization. The lignin is obtained as a precipitate which separates from the liquid; the liquid solvent, usually ethanol or acetone, is evaporated; then the drained lignin is redissolved in the minimal quantity of acetone; a new precipitation with an excess of water allows to obtain the lignin in the form of a slightly coloured powder. A prolonged boiling dehydrates and disaggregates the sugars; by the strong acids action, takes place the formation of light molecular weight or microcristalline cellulose, glucose or organic acids, methanol and furfuralic compounds.
