Patent GB-199691-A (GB)
Title: Improvements in or relating to the manufacture of electric incandescent lamps
IPC: H01J9/38
Filed: 1922-09-09
Abstract: 199,691. Handelsvennootschap onder de Firma Vogels & Co. June 26, 1922, [Convention date]. Residual gases.-In manufacturing gas-filled incandescent lamps, the bulbs are subjected to a partial evacuation by means of a " pre-vacuum " pump and are filled with an inert gas or vapour which is exhausted, this step being repeated one or more times before the lamps are finally filled with an inert gas or vapour and sealed off with a content at a pressure of 45 to 76 mm. The lamps may be raised to the usual pumping temperature and a reducing agent may be introduced before pumping takes place. The Figure shows means for closing the lamps separately on the fork before sealing off in such a way that fracture or air leakage in any one does not affect the gas filling of the others. The bulbs 2 on the fork 1 are connected by tubes 3, 4, 5 to the pump which may be shut off by the cock 6. The filling gas supply is regulated by a cock 8, and mercury may be introduced into the fork from a supply 10 for shutting off the lamps. During pumping, the cock 11 is connected to a vacuum tube of the pump so that mercury is withheld from the fork, but when the lamps are to be removed or when air leaks into any of them, the cock 11 is connected to a compressed air pipe so that mercury enters the fork and closes off each lamp separately. The Specification as open to inspection under Sect. 91 (3) (a) describes a process in which the pressure of the gas finally left in the bulb before sealing is not limited to the range of 45 to 76 mm. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the production of puffed cereals
IPC: A23L1/18
Filed: 1936-01-17
Abstract: Puffed products are obtained from cereals having a fat content of less than 4,5 per cent by subjecting the raw cereals in an otherwise unheated closed container to the action of superheated steam at a pressure of at least 100 lb. per square inch and at least 25 DEG  F. of superheat for a period of the order of five minutes or less, the pressure then being suddenly reduced to puff the cereal.  In a specific example, maize with a fat content of less than 4,5 per cent is treated with steam at a gauge pressure of about 220 lb. per sq. inch and with about 150 DEG  F. of superheat for about one minute after line pressure has been attained.  The container is then opened to release the pressure.  Salt may be added to the grain before the steam treatment, a suitable proportion being about one ounce of salt to each pound of maize. Specifications 472,465 and 472,466 are referred to.

Title: Improvements in and apparatus for the gasification of fine-grained fuels
IPC: C10J3/46
Filed: 1933-09-11
Abstract: 421,356. Gas-producers. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.- (I. G. Farbenindustrie Akt.-Ges.; Frankforton-Main, Germany) Sept. 11, 1933, No. 25125. [Class 55 (i)] Fine grained solid fuel is gasefied by blowing through an incandescent layer of the fuel a gasefying-agent such as oxygen, air, carbon dioxide, steam, or mixtures of these gases, together with a combustible gas such as water gas, or producer gas, at such a speed that a movement similar to boiling is established in the fuel, in a manner similar to that described in Specification 214,544, [Class 55 (i)]. The fuel is fed from a hopper 9 on to a fuel bed 8 into which lead nozzles 7 for the oxygen supply. Steam is blown in below the grate 3, and the water gas obtained passes by an outlet 12 through a dust separator 13 from which the separated dust returns to the fuel bed. The water gas passes through a washer 16, and fan 20, to a receiver 22, a branch pipe 25 leading a supply of water gas to a steam injector 27 which forces it into the fuel bed from below. Oxygen may also be supplied above the layer of fuel. Slag and ashes are withdrawn through outlet 5. An addition of steam is unnecessary if the fuel has a sufficiently high content of water or hydrogen. Waste gases from the destructive hydrogenation of coal, tars, or mineral oils, or from the synthesis of ammonia, may be used as the combustible gases.

Patent GB-464860-A (GB)
Title: Process for waterproofing textile materials
IPC: D06M15/263
Filed: 1935-09-17
Abstract: Textiles are made water-repellent by treatment with a mixed polymerizate obtained by common polymerization of maleic anhydride with either a vinyl fatty acid ester or a vinyl ether containing at least 12 carbon atoms in the molecule.  The polymerizates can be made by the process described in Specification 376,479.  The free acids obtainable by opening the anhydride by hydrolysis or functional derivatives of the acid other than the anhydride may also be used, e.g. esters and amides.  Esters may be obtained by using appropriate mono and di-esters of maleic acid instead of maleic anhydride for the polymerization.  In examples: (1) cotton fabric is impregnated with a methylene chloride solution of the mixed polymerizate from vinyl stearate and maleic anhydride, dried and heated to about 100 DEG  C.; (2) cotton or artificial silk is similarly treated with the mixed polymerizate from vinyl palmitate and maleic acid and may be further treated with aluminium formate; (3) loose wool is treated with the mixed polymerizate from vinyl stearate and maleic anhydride; (4) cotton or artificial silk is treated with the mixed polymerizate from vinyl octodecyl ether and maleic anhydride, or from maleic anhydride and the vinyl ether of the alcohol mixture obtained by reduction of coconut oil fatty acids; (5) cotton fabric is treated with the mixed polymerizate of maleic anhydride and vinyldodecyl ether; (6) viscose artificial silk is treated with the mixed polymerizate of maleic anhydride and the vinyl ether of montan wax alcohol; (7) cotton or viscose artificial silk is treated with the mixed polymerizate from vinyl stearate and the semi-ester of maleic acid with octodecyl alcohol; (8) cotton or artificial silk is treated with the mixed polymerizate from vinyloctodecyl ether and maleic acid dimethyl ester; and (9) loose wool is impregnated with the free acid of the mixed polymerizate from vinyloctodecyl ether and maleic anhydride.

Abstract: 972,734. Fuelling reactors. UNITED POWER CO. Ltd. Oct. 4, 1963 [July 5, 1962], No, 25855/62. Heading G6C. A charge machine 1 is rotatably supported by a shoulder 2 and bearing 3 on an annular structure 4 having wheels 8 surrounding the machine 1 at its lower end. The wheels 8 are single wheels and a plurality are provided arranged on parallel axes around the structure 4, each wheel having an axle 9 carried by an arm 10 pivotally connected at one end to a bracket 11 fixed to the structure. The other end of the arm 10 is connected to the ram 12 of a hydraulic ram assembly 13 so that by extending the rams the machine 1 is raised clear of the reactor charge floor 21 to permit movement of the structure 4 by driving the wheels 8, whereas by retracting the rams, the machine 1 rests on the floor 21 and the wheels 8 are raised clear of the floor. In this condition the structure 4 may be rotated on the machine 1 by operating a motor 18 mounted on the structure, this motor driving a pinion 19 meshing with an annular gear 20 fixed to the machine. Thus the wheels 8 may be orientated so that when they support the machine on the surface 21 the machine is driven in the desired direction. Each wheel 8 may have its own driving motor (Fig. 2, not shown) and this motor may be electric or hydraulic. In a modification (not shown) the arms 10 are omitted and the wheels 8 are mounted directly on the lower ends of telescopic rams. T.V. cameras may be mounted beneath the structure 4 to observe the standpipe with which the machine is to be aligned.
