Abstract: 143,310. Macdonald, D. B. Feb. 19, 1919. Stiffeners.-A toe puff or like stiffener comprises face and back layers a, b, Fig. 1, and one or more intermediate layers c of reticulated material coated or impregnated with a stiffening-agent in solution in a volatile solvent; in some cases, one or more middle layers d, Fig. 2, are used to carry the stiffening-agent. In one arrangement, the face layer a is made of white croydon, linen, or like textile material, preferably filled so as to be non-porous, the layer b is made of duck, and the layer c of muslin or equivalent, and the layer d, when used, of swansdown or jute fabric such as hessian. The stiffening-agent is preferably one containing celluloid in solution; but it may have mixed with it an inert material such as shoddy, vegetable charcoal, fibrous cotton, wool, or leather. The puffs may be made of layers cut to shape and then assembled, or they may be cut from materials assembled in sheet form; in either case, the layers may be graded in size so as to form a thin edge such as at e, Fig. 1. The puffs are intended to be kept moist ready for assembling in a boot, and for this purpose they are packed closely one upon another and kept in tins or other suitable containers, being preferably arranged in alternating revised position, as shown in Fig. 6. Specification 145,868, [Class 94 (i), Packing &c.], is referred to.

Title: Treatment of hydrocarbon lubricating oils
IPC: C10M177/00
Filed: 1953-05-12
Abstract: The tendency of a hydrocarbon lubricating oil to deteriorate as the result of oxidation is reduced by using, in contact with the lubricating oil in an I.C. engine, a crank case drain plug bearing on its inner end metallic sodium, potassium, lithium or calcium or alloys of such metals other than an alloy of sodium and lead-tin solder.  Alloys referred to are sodium amalgam and alloys of sodium and cadmium, sodium and tin and calcium and silver.  At least 1/4 per cent of the metal or alloy based on the weight of oil treated may be used.  It is thought that the presence of the metals or alloys in contact with the oil stabilizes the hydroperoxides formed on oxidation of the oil, or decomposes these hydroperoxides to liberate free oxygen.

[Also in Division H2] An anticollision navigation light for an aircraft or other vehicle consists of a lamp mounted along the longitudinal axis of a cylindrical enclosure containing a unit comprising a reflector, a carrier and a driving means connected to the carrier and to an exterior source of power so that the unit can revolve about the axis of the enclosure, the reflector and carrier having apertures through which the lamp extends. The enclosure consists of a coloured transparent cylinder 2 closed at one end by a plate 3 having a recess to receive one end of a tubular filament lamp 15, preferably an iodine lamp, and at the other by a plate 1 having an extension 16 of reduced bore to receive the other end of the lamp and containing a spring-pressed block 17 having a contact 18 for the lamp. A reflector 28 recessed to receive the lamp is mounted on a toothed disc 30 engaging a gear 33 on the shaft of a motor 6 for rotating the reflector. The extension 16 has cooling fins 22 between which are air inlets 36 while the plate 3 carries streamlined vertical cooling fins 24 and ventilating channels 25 for emission of air, which may be regulated by bimetallic strips 26 responding to the temperature of the lamp. The reflector 28 has helical fins 29. A casing 4 supported by a cap 20 closing the extension 16 also encloses the terminals 35 of the motor 6 and forms one terminal of the lamp circuit. Radio noise suppression filters are accommodated in the casing 4. A cylindrical colourless lens may be mounted inside the cylinder 2 and the lamp may then be connected to a flashing mechanism, the reflector and rotating mechanism being dispensed with. The light may also be used on sea-going vessels or motor vehicles. The cylinder 2 may consist of heat-resistant glass having a surface coating of cement or a micrometric coating of coloured plastics.

Title: Improvements in or relating to the electrodeposition of copper by fusion electrolysis
IPC: C25D3/66
Filed: 1944-03-15
Abstract: 575,394. Fusion electrolysis. IMPERIAL CHEMICAL INDUSTRIES, Ltd., (Du Pont de Nemours & Co., E. I.). March 15, 1944, No. 4798. [Class 41] A process for the electro-deposition of copper consists of the electrolysis of a fused inorganic salt bath containing copper cyanide and not less than 1 per cent. of an alkali metal cyanide, e.g., sodium cyanide or a mixture of sodium and potassium cyanides. To obtain a dense, adherent coating the melt contains not more than 5 per cent. by weight of copper cyanide, the current being between 7 and 35 amps. per square foot and the temperature not greater than 600‹C. If a spongy deposit is required the copper cyanide content is increased to between 10 and 50 per cent. by weight ; control of the current density is not necessary in this case except to regulate the rate of formation of copper. The melting point of the salt bath may be reduced by the addition of fusible diluents such as sodium carbonate, sodium chloride, potassium chloride or sodium hydroxide. The metal surface to be coated may be cleaned by making it the anode in the fused electrolyte and then passing a current of a density of from 10 to 40 amps. per square foot.

Title: Improvements relating to extracts of the internal secretory organs of females
Filed: 1928-02-16
Abstract: 285,856. Soc. of Chemical Industry in Basle. Feb. 23, 1927, [Convention date]. Medicines for internal use.-In the preparation of active extracts from female organs, such as ovaries, placenta and corpus luteum, the fresh organs are strongly cooled by admixture with an inert refrigerating agent such as carbonic acid snow, so as to become hard, are pulverized whilst in this condition, if desired with the addition of an agent which combines with water, and the powder thus obtained is extracted with a solvent and the extract purified in the usual manner. According to one example, fresh ovaries are immersed in carbonic acid snow and then ground together with the snow and calcined sodium sulphate. The powder is extracted with ether, and the filtered extract is concentrated in vacuo at low temperature, mixed with acetone, and cooled to -70‹ C. to produce a precipitate. The solution in acetone-ether after removal of the precipitate may be freed from solvent in a vacuum either directly or after solution in olive oil or sesame oil. In another example, placenta is cooled and ground and extracted with alcohol, the alcohol is distilled off and water is added to form an emulsion which is extracted with ether. The ether solution is concentrated and further treated as in the previous example. According to a third example, ovaries, powdered as before, are extracted at low temperature with acetone and the solvent evaporated off in vacuo. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the particular method of cooling referred to above, and relates also to the use of a solution from which the solvent has not been removed, and to a process of removing the solvent by exposing the solution to olive oil or sesame oil in a vacuum. This subject-matter does not appear in the Specification as accepted.

Abstract: 550,134. Carboxylic acids. WEIZMANN C. April 18, 1941, No. 5054. [Class 2 (iii)] Carboxylic acids are produced by oxidation with molecular oxygen of the corresponding aldehydes in the presence of double compounds or mechanical mixtures of a plurality of salts of multivalent metals with unsaturated fatty acids such as oleic acid. The catalyst may be prepared from salts of the metals and soaps or by reacting the acids with the metal oxides, hydroxides or carbonates. Preferably the anhydrous metal carbonates are heated with the equivalent quantity of the unsaturated acid at 120-130‹ C. and applied in the form of a suspension in a small quantity of the aldehyde. Examples describe the production of butyric and n-heptoic acid from butyraldehyde and oenanthal respectively by means of a catalyst comprising the oleates of lead manganese and cobalt.
