Title: Fuel filter water separator element
IPC: B01D35/00
Filed: 1963-08-07
Abstract: A hollow tubular separator element for separating water from fuel in the second stage of a filter-separator consists of a ribbon of resinimpregnated paper, cellulose or the like having rugosities extending across both its surfaces, the ribbon being wound edgewise simultaneously with a narrower or perforated strip which includes, or consists of, a hydrophobic (e.g. P. T. F. E. or a polyester) material.  After winding, the parts of the surfaces of ribbon which are in contact are bonded together by heating to set the resin.  On setting, the ribbon is impervious to liquid, but interstices between the convolutions are provided by the rugosities.  Where the strip is narrower than the ribbon, one of the strip edges preferably is aligned with that edge of the ribbon which is at the inlet surface of the element.

Title: Improvements in or relating to melting furnaces
IPC: F27B14/00
Filed: 1945-11-21
Abstract: 604,033. Melting - furnaces. FAIRWEATHER, H. G. C. (National Smelting Co.). Nov. 21, 1945, No. 31369. [Class 51(ii)] A furnace for melting light alloys is heated by combustion products in refractory tubes which are surrounded by the refractory material of the hearth. As shown in Fig. 1, a burner, or burners, 11 having fuel and air connections 12, 13 is or are, connected to a tube or tubes 9 beneath the . floor 2 of the hearth, the the combustion products passing to interconnected vertical tubes 8 in one or both side-walls 6, and to a stack or stacks 10. The tubes may be of a steel alloy containing a large amount of nickel, of nickel alloy or of silicon carbide. The hearth may be of silicon carbide, graphite or mixtures thereof. To avoid breakages due to expansion differences between the tubes 8 and the surrounding refractory material, the tubes are coated with a combustible material, e.g. a thick starch paste, before they are embeded in the plastic refractory material. The subsequent destruction of the starch provides room for differential expansion. In a modification, the burner tubes, one in each side wall, are .directed downwardly, the combustion products passing tortuously through the pipes in the side walls before passing to the stacks through pipes under the hearth. In Fig. 8, the burner tubes 9 are connected to a header 25 which communicates with the tortuous pipes 8 in the side walls and the bottom pipes leading to stacks 10. The metal in the bath is heated, in part, by radiant heat from the tubes 9. The chamber 29 is used for feeding in the alloying ingredients and for the removal of the molten alloy. It may be separated from the heated part of the furnace by a sliding wall 30a. Access to the furnace for skimming the surface of the molten alloy is obtained by raising the wall 30a, and, in a modification, through a doorclosed opening in the opposite end wall of the furnace.

Abstract: The invention comprises compounds of the formula <FORM:0699818/IV (b)/1> where R is alkyl, aralkyl or cycloalkyl, X is hydrogen, halogen or nitro and Y is a dicarboxylic acid imide group attached by its nitrogen atom.  These are made from the corresponding amino-acids <FORM:0699818/IV (b)/2> by conversion into the dicarboxylic acid derivative, e.g. by reaction with phthalic or succinic anhydride, and treatment of the product with a halogenating agent such as thionyl chloride or phosphorus pentachloride, pentabromide or tribromide. The amino-acid or its dicarboxylic acid derivative may be resolved into optically active forms before or after conversion to acid halide.  It is stated that the stereo configuration is not changed during the reactions.  Examples show the production of 2-phenyl-2-methoxy-1-phthalimidopropionic acid and its chloride and their p-nitro and p-bromo derivatives.  R may also be ethyl or benzyl.  Amino-acids of the second formula above are prepared by treating the corresponding halogen compounds with aqueous or alcoholic ammonia.  Examples give the production of 2-phenyl-2-methoxyalanine and its p-nitro and p-bromo derivatives. Halo-acids of the formula <FORM:0699818/IV (b)/3> are made from cinnamic acid or a substituted cinnamic acid by (1) addition of hypohalous esters, e.g. methyl, ethyl or benzyl ester of hypochlorous, hypobromous or hypoiodous acid; the latter is preferably prepared in situ by treating an alcoholic solution of the cinnamic acid with halogen in the presence of an acid binding agent such as lead oxide or silver nitrate; (2) (R=methyl, X=H, Halogen= bromine) treatment of cinnamic acid with mercury acetate, methanol and an alkali bromide to give the 1-bromomercuri-derivative and decomposition of the latter with bromine.  In the examples 2-phenyl-2-methoxy-1-bromopropionic acid and its p-nitro and p-bromo derivatives are made by method (1).

Abstract: 172,942. Ges. f³r Drahtlose Telegraphie. Dec. 14, 1920, [Convention date]. Directive signalling; aerials and like receiving conductors.- In wireless directionfinding apparatus employing frame-aerials R, means are provided for ccmpensating errors due to inclination of the incoming wave-front, and, in cases where the frame-aerial itself can be inclined, for equalizing its proper angles of inclination for the two minimumaudition positions by compensating for asymmetrical earth-capacity in the system. The fixed plates of a condenser C and the casing connected therewith have a larger capacity to earth than the movable plates. This inequality may be compensated (i) by connecting an auxiliary aerial to the movable plates or by two unequal compensating aerials as well as the frame aerial R; (ii) by selecting an earth-point E in an asymmetrical pcsition on the frame aerial R; (iii) as indicated in Fig. 3. by insulating both sets of plates from the metal case M; or (iv) as indicated in Fig. 4, by employing two condensers symmetrically arranged. Two or more of the above methods may be used in combination. Inclination of the incoming wave-front may be compensated by using one or more of the above-mentioned devices with either a vertical or an inclined aerial.
