Title: Improvements in and relating to electron discharge tubes
IPC: H01J9/395
Filed: 1934-05-04
Abstract: 437,529. Producing high vacua. ALLGEMEINE ELEKTRICITATS-GES., 2, Friedrich Karl-Ufer, Berlin. May 4, 1934, No. 13596. Convention date, May 4, 1933. [Class 8 (i)] [See also Group XL] Alkaline earth metals are introduced into electron discharge tubes, as " getters for the production of high vacua, by introducing a mixture of an alkaline earth metal alloy with an oxide or other substance which, when the mixture is heated within the tube to moderate " glowing temperatures of about 550‹ C., reacts with the metal alloyed to the alkaline earth metal and liberates the alkaline earth metal. The mixture may be 60-90 parts of aluminium alloy and 10-40 parts of iron oxide, chromium oxide or tungsten trioxide, the alloy containing 15-60 per cent of alkaline earth metal such as barium. The mixture in the form of compressed powder is heated by high-frequency currents and the oxide reacts with the aluminium but not with the barium. The reaction is exothermic, the heat developed and the rising percentage of barium in the alloy as the reaction proceeds assisting in the liberation of the barium. The aluminium may be replaced by zirconium, thorium, scandium, beryllium or rare earth metals. If the metal chosen does not form a binary alloy with the alkaline earth metal, a third metal, such as nickel, not participating in the reaction is added. The oxide may be replaced by sulphides or halogen compounds initially heated to reduce their absorption of gases. An excess of the metal alloyed to the alkaline earth metal or another reaction material may be added to the mixture to graduate the heat of reaction.

Title: Improvements in or relating to the ventilation of the battery basements of under-jetcoke ovens
IPC: C10B29/00
Filed: 1945-05-30
Abstract: 604,211. Retort furnaces. KOPPERS CO., Inc. May 30, 1945, No. 13601. Convention date, May 8, 1944. [Class 51(ii)] [Also in Group X] The basement 22 of an underjet coke-oven battery, providing passageways accessible to operators for regulation of gases to and from the heating flues, is ventilated by introducing and withdrawing air at opposite sides through a number of longitudinally spaced openings communicating with the outside air. Alleyways 36, 38 at the pusher-side and coke-side of the battery, having side walls with louvred ports 37 are interconnected at both ends by similar alleyways beyond pinion walls 39 which support the battery masonry and at the basement level have air-tight doors 41. A conduit 53 below the cokeside alleyway forms a reservoir for supplying air and communicates at one end with an enclosure 57 leading to a transverse conduit 58 which connects through louvred openings 59, 86 with alleyways 36, 53, A fan 63 draws in air from outside through openings 61, 62 and delivers it into conduit 53 at above atmospheric pressure whence it is. equally distributed into the basement through louvred openings 66. As its temperature increases the transverse air current rises towards outlets around regenerator flow boxes 26, one portion passing into the flow boxes for combustion purposes and another, after being heated by contact with the flow boxes which carry combustion products to a waste heat duct 24 rising through a space 70 and thence after diversion by baffles 76 up through stacks 79 formed by plates 80 welded to the flanges of buckstays 15. A third portion is diverted back along the basement roof insulating rich fuel gas pipes 31 from the cooler current below, thus avoiding condensation in orifices leading to underjet ducts 27. By adjustment of louvres in openings 59, 61, 62, 86, varying proportions of air from the alleyways may be mixed with the outside air which in cold weather may be excluded altogether. The fan may be controlled so as to cause to be delivered to the regenerators a uniform weight of air irrespective of pressure or humidity fluctuations of the outside atmosphere. Owing to the heating effect in space 70 which establishes an air flow across the basement the fan may be dispensed with; grilles replacing covers 84 in the ceiling of conduit 53 may enable air to be drawn in from alleyway 38.

Title: Improvements in or relating to the manufacture of paints
IPC: C09D191/00
Filed: 1929-05-02
Abstract: 335,626. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 2, 1929. Pigments.- Weather-resistant paints are made by incorporating into paints or other coating materials at least such a quantity of precipitated zinc oxide dried by heating to a temperature not materially exceeding 500‹C. as is necessary to combine into soaps all free or combined fatty acids present in the binding agent. Such zinc oxide is stated to possess the property of reacting quickly with the binding agents used in paints, such as linseed oil and wood oil, to form metallic soaps, which are attacked with difficulty by the atmosphere. Paints containing other pigments such as white lead, commercial zinc white, colcothar, permanent white &c., are improved by using at least the quantity of the zinc oxide specified necessary for the neutralization of the acid complex present in the binding agent, the remaining quantity of pigment being of the customary character, i.e. known to exert a slow reaction as regards soap formation. The paints may be made by mixing the respective pigments in the dry state or by incorporating the zinc oxide specified with the composition produced from the commercial pigments with the usual binding agents. In an example, 80 kgs. of lithopone containing 30 per cent ZnS are mixed with 20 kgs. of precipitated zinc oxide ignited at a temperature not exceeding 500‹ C. and made into a paint with 45 kgs. of linseed oil varnish; or alternatively 70 kgs. of titanium white and 30 kgs. of similar zinc oxide are mixed with 80 kgs. of linseed oil varnish. Lithopone containing more or less ZnS may be used, and titanium white may be replaced by colcothar. Specification 256,302 is referred to.
Patent GB-574014-A (GB)
Title: Improvements in or relating to the production of textiles and other articles having a basis of a polyvinyl compound
IPC: C08F8/12
Filed: 1941-10-24
Abstract: Shaped articles such as threads, foils, &c. having a basis of a polyvinyl ester are saponified while retaining their structure by means of a solution of a saponifying agent in hexyl alcohol or a higher homologue thereof.  The process may be continued until the products are soluble or easily dispersible in water, and such products may be employed for making cords, ropes, fabrics and other parts of parachutes for minelaying.  The hexyl alcohol may contain methyl or other lower alcohols or even water provided the liquid as a whole has no deleterious effect on the properties of the product. The polyvinyl ester treated may consist of polyvinyl acetate, polyvinyl butyrate, or other ester, polyvinyl chloride, or a copolymer, and the filaments may be formed by extruding a solution of the polyvinyl compound in acetone, dioxane, or other volatile solvent into a chamber through which hot air or other evaporation medium may be passed in the same direction as the filaments.  The filaments are then passed through a solution of a wetting agent and washed in cold water.  In a wet spinning process, a dilute aqueous solution of acetic acid may be employed as the coagulating bath.  The filaments may be stretched to increase their tenacity 300 or 400 per cent of their original length in water at 50 DEG  to 70 DEG  C. and afterwards set by immersing them for several hours in water, or they may be stretched in air. The stretching may also be effected after saponification.  In an example, polyvinyl acetate yarn in hank form is immersed in a 0.2 per cent solution of sodium hydroxide in hexyl alcohol at 25 DEG  C., the ratio of solution to yarn being 30 to 1. The hanks are turned at intervals and allowed to remain in the bath until complete saponification has been effected.  They are then washed with hexyl alcohol and dried.  The saponified materials may be reacted with reagents to combine with the free hydroxy groups such as formaldehyde, acetaldehyde, and ketones, or with reagents containing two esterifying radicles such as succinyl, adipyl, or phthalyl chloride or a dianhydride such as a mixed anhydride of acetic acid and a dicarboxylic acid such as succinic, adipic, or phthalic acids. Threads &c. containing chlorine or other halogen atoms may be reacted with diamines, for example, ethylene diamine, hexamethylene diamine, or paraphenylene diamine.  Specification 482,216 is referred to. According to the Provisional Specification, the polyvinyl compound may contain hydroxy groups from the start provided the proportion is not so great as to render it insoluble in organic solvents, and the filaments may be saponified either before or after they are converted into fabrics. Specification 454,425 is referred to.
