Abstract: 243,501. Green, E. W., Ogden, H., and Unthank, G. R. Oct. 29, 1924. Filter-beds; purifying liquids. - Water contaminated with oil is distributed over a large wetted area, exposed to the air, which will retain the oil temporarily till it forms drops which are removed by the slowly flowing water and subsequently trapped. A tank f containing coke, pumice stone, shingle, pieces of marble, or the like, or fibrous material, and having a bottom formed as a grating, is mounted in a tank a and is supplied with the contaminated water by a trough i having a perforated bottom. A partition b extends from the top of the tank to near the bottom, where it is bent parallel to the botom of the tank. The filtered water flows under the partition band over a weir c of such a height as to ensure that sufficient liquid remains in the tank a to trap the coalesced drops of oil which collect on the surface of the liquid. Trap doors l are provided for the removal of sludge.

Filed: 1923-10-23
Abstract: 209,038. Soc. d'Optique et de MÚcanique de Haute PrÚcision. Dec. 30, 1922, [Convention date]. Modifying scale of readings.-Apparatus for transforming the displacement of a member, e.g. that used for the determination of the range in rangefinders &c., into a displacement of another member inversely proportional to that of the first member, includes a guide curve C in the form of an hyperbola with which contacts a roller G. The movements of this roller G in longitudinal and transverse directions are transmitted to pinions L<1>, L<2> in such a manner that the rotation of one of the pinions is inversely proportional to that of the other pinion. The asymptotes of the hyperbola may be at any angle with one another. The guide curve C is secured to a frame D in which slides - a carriage E supporting a rack F to which is attached the roller G. Two pinions I<1>, P, rigidly connected to pinions J<1>, J<2>, are also mounted on the carriage E, the latter pinions engaging racks K<1>, K<2> respectively. These racks actuate pinions L<1>, L<2> carried by the frame D. The equation of the hyperbola being (a/b y-x) (a/b y+x) = 1, the ratio of the pinions I<1>, J<1> and I<2>, J<2> b/a, is so that when the carriage E is moved by the handle R the rack K<1>will move a distance equal to a/b y+x) and the rack K<2> a distance equal to (a/b y-x) rotating the pinions L<1>, L<2> through angles inversely proportional to one another. In place of the gearing indicated, a continuous band passing over rollers and carrying the racks K<1>, K<2> may be used, being directly attached to the guide roller G. A modified form of apparatus is also described utilizing a hyperbolic guide based on polar coordinates.

Title: Improvements in or relating to methods for the production of hard alloys
IPC: C22C1/05
Filed: 1931-09-22
Abstract: Hard alloys particularly for making toolbits, wire drawing dies, &c., are produced by mixing a powder comprising tungsten carbide, with or without 3-20 per cent of tungsten powder, with at least 20 per cent of a metallic alloy which contains 50-85 per cent of tungsten and one or more of the metals iron, nickel, cobalt, chromium, titanium, vanadium, molybdenum, and which after having been melted and solidified is finely pulverized.  The mixture is formed to shape by pressing or otherwise, and sintered. In an example commercial tungsten and the auxiliary metal or metals are melted in a graphite crucible, poured on to a cool slab of carbon or graphite and pulverized.  To prevent excessive absorption of carbon during melting, the auxiliary metal may be introduced in the form of oxide. The mixture is added to powdered tungsten carbide which may contain tungsten and sintered in an electric furnace.  If a large quantity of metal is sintered the articles are cooled rapidly immediately after reaching the sintering temperature.

Abstract: 641,671. Protective cut-out arrangements. BENDIX AVIATION CORPORATION. Oct. 3, 1947, No. 26697. Convention date, Oct. 4, 1946. [Class 38(v)] In a system in which D.C. generators supply a common load, each generator has a circuit breaker which opens the field circuit in the event of failure of the regulator controlling the field circuit. The Fig. shows generators 1, 2 supplying a common load and having shunt field windings 3, 4 each controlled by a voltage regulator having a carbon pile 23 actuated by a winding 19 in shunt with the generator armature. A circuit breaker 27, connected in series with each field winding is normally held closed by a latch 31 against the compression of a spring 30. The latch may be disengaged by an electromagnet having a winding 34 connected in parallel with the field winding. In the event of a carbon pile 23 becoming short circuited, or in the event of the open circuiting of a winding 19 causing a pile to be fully compressed, an increased voltage would be applied across the associated field winding and across winding 34, which unlatches the circuit breaker 27 to open the field circuit and so prevent the generator from attaining an excess voltage due to over-excitation. Specification 625,825, [Group XXXV], is referred to.

Title: Improvements in or relating to the production of moistureproof film
Inventor: BERRY WILLIAM
IPC: C08J7/048
Filed: 1948-10-14
Abstract: In the production of moisture-proof solid films of water-sensitive non-fibrous organic material of types which normally develop when immersed in water, an electric charge of negative sign, but which may be so treated that they develop charges of positive sign under these conditions, an aqueous dispersion of a partially condensed urea-formaldehyde or thiourea-formaldehyde resin, of which the particles carry an electric charge of opposite sign to that developed by the base film in contact with water, is applied to the base film to form an anchor coating for a subsequently-applied moisture-proofing coating.  In examples there are described (1) the treatment of purified gel regenerated cellulose film with an aqueous solution containing glycerol and "Beckamine" (Registered Trade Mark) L101, a urea-formaldehyde resin which can be diluted with water to give a dispersion of positively charged colloidal particles; (2) the restoration of the charge on the particles of "Beckamine" L101, which had become negative in the course of time, to positive, by treatment with cetyl pyridinium bromide, tetradecyl pyridinium bromide, and "Lissolamine" (Registered Trade Mark) A-50, a paste containing cetyl trimethyl ammonium bromide, and the use of the so-treated dispersions in admixture with aqueous solutions of glycerine; (3) the production of a partially condensed thiourea-formaldehyde resin by heating together thiourea, formalin, sodium acetate, glacial acetic acid and "Lissolamine" A-50, cooling and neutralizing with sodium hydroxide solution, the resulting resin being mixed with an aqueous solution of glycerol and urea and applied to a regenerated cellulose film, the charge on the dispersed resin particles being positive; (4) the production of an aqueous dispersion of a partially-condensed urea - formaldehyde resin having positively charged particles by heating together urea, formalin, sodium acetate, glacial acetic acid, adding cetyl ethyl methyl sulphonium bromide, or cetyl triethyl phosphonium bromide, and, after further heating and cooling, neutralizing with caustic soda solution; the resins are applied to a regenerated cellulose film in admixture with an aqueous solution of glycerol and urea.  Acidic condensing agents for the insolubilization of the resin, including inorganic acids, e.g. phosphoric acid, organic acids, e.g. salicylic, gluconic or citric acids, salts which become acidic when heated under the conditions used, e.g. ammonium thiocyanate, acid esters and acid resins, may be added either to the partially condensed resin or to the subsequently applied moisture-proofing coating.
