Title: Process for the manufacture of a colloidal product from wool fat
IPC: A61K8/92
Filed: 1936-10-15
Abstract: A product which is colloidally soluble in water is obtained by bringing wool fat, or purified fractions thereof, into contact with an alkali metal, either at an elevated temperature or in the presence of an organic solvent which is indifferent towards the alkali metal used.  The metal which remains undissolved is filtered off or removed, and the solvent, if used, evaporated. The product, which is of soft wax-like consistency, forms a cream-like emulsion, on triturating with a small quantity of water, which on further dilution yields a weakly alkaline colloidal solution.  In examples, wool fat is heated in the presence of metallic sodium or potassium, a solution of wool fat in petroleum ether, benzene or xylene is boiled in the presence of sodium or potassium, and wool fat dissolved in benzine is allowed to stand in contact with sodium.

Filed: 1954-09-29
Abstract: 759,984. Fuel injection systems. FRENCH, L. O. Sept. 29, 1954, No. 28109/54. Class 7(3) [Also in Group XXVIII] A fuel injection pump is actuated by the pressure in the engine cylinder acting on a piston 23 which carries the cylinder 24 of the pump which is loaded by a spring 46 and slides on a relatively fixed piston 41. Fuel is supplied to inlet 9 and circulates through the well 7 and passage 12 to the chamber 11 and outlet 10. The chamber 40 forms a sealing and bufferchamber and is connected to the chamber 11 by a groove 39 on the cylinder 24 and by a port 13 'and an adjustable relief valve 18 also to the chamber 11. When the pressure in the engine cylinder rises, the piston 23 is raised and the groove 39 closed, to trap fuel in the chamber 40. The pressure in chamber 40 continues to rise until it opens the valve 18 and injection takes place until the piston 23 covers the port 13; the loading of valve 18 determines the beginning of injection. In an alternative arrangement, the valve 18 is actuated mechanically in timed relation with the engine. The pump cylinder 24 has an inlet port 37 and the piston 41 a control edge 42 and is adjusted by lever 45. The fuel is delivered through a passage 34 and a triangular non-return valve 35 to the nozzle 33. Specification 719,589 is referred to.

Abstract: 646,565. Roofs; walls; corrugated metal sheets. BRIGGS & SONS, Ltd., W., and MARCH, G. A. Sept. 19, 1946, No. 28125. [Classes 20(ii) and 20(iv)] A corrugated metal sheet for use in a roof decking structure is formed to present a substantially flat surface on one side having a number of narrow, flat-bottomed, parallel channels therein, the channel sides being inclined outwardly from their bottom surfaces. In the roof structure shown in Fig. 1, corrugated aluminium sheets 10, having wide, longitudinal, flat surfaces 10a separated by narrower channels with flat bottoms 10b and outwardly inclined sides 10c, are supported with their ends resting on purlins 11, adjoining sheets having overlapping, longitudinal flanges 10d and 10e. To secure the sheets, a bar 12 is provided along the length of each purlin 11 above the centre line thereof, the bar being spaced from the upper surface of the purlin by projections 12a, by which it is welded to the purlin. Wooden wedges 13 are placed in the channels and driven through the slot between the bar and the purlin thus securing the ends of adjacent sheets. Insulating boarding 14, roofing felt 15 and bitumen 16 are applied on the flat surface of the sheets to complete the roof. In a modification, Fig. 5, the channels in each sheet are opened out at one end 10f and a hole 10g is provided at the ends of portion 10b in each channel. The sheets are then inter-fitted end to end with the holes 10g in register, studs which have been welded to the purlin 11 passing up through the holes, so that the sheets may be secured by washers and nuts. The construction may be used for vertical walls, when surfacing boarding is applied to the inner side of the sheets 10. Specification 537,108 and U.S.A.

Front and side flaps of the hinged lids of cartons 3 are sealed to the carton walls by indexing the cartons through a passage having pairs of high-frequency electrodes 28-33, one pair in each of the three sides corresponding to the flaps to be sealed and sealing taking place as a flap passes between the electrodes of its respective pair. Photo-electric means 18, 19 is actuated by an accumulation of jammed cartons to stop the machine, is caused by the cartons to switch on the electrodes as they enter, or if cartons are not supplied at given intervals, is actuated by their absence to switch off the electrode current. Each of a pair of walls 22, 23 is pivoted at the base and operated by cam means 40 to cause them to move apart during upward movement of the cartons. In addition, they may move together relative to the third sealing wall 26 to prevent cartons sticking to the latter.

Abstract: 1442638 Semi-conductive coatings HUTA SZKLA IM PAPLINSKIEGO 15 June 1973 [17 June 1972] 28493/73 Heading B2E [Also in Divisions H3 and H5] Semi-conductive coatings on an electric heater are obtained by applying a composition obtained by mixing together an extrinsic semiconductor and a material having cations whose ionic radius is at least 20% less than the ionic radius of the cation of the major constituent of the semi-conductor (a so called thermoelectric buffer material), repeatedly melting the mixture and after each melting stage cooling and comminuting the mixture. The semiconductor and thermo-electric buffer may be mixed together in solution in a liquid or in dispersion in a liquid. The semi-conductor may be n or p type. The buffer is selected from oxides, halides, organometallic compounds, carbides and carbonates. In one specific example a semiconductive composition comprising hydrated stannic chloride, antimony trichloride, ammonium fluoride, cuprous oxide, boric acid (thermo-electric buffer) and cadmium chloride prepared by repeated melting, cooling and simultaneous comminution was applied by sublimation or electrostatic dusting to a glass surface coated with a semi-conductive mixture of hydrated stannic chloride, antimony trichloride and ammonium fluid to form a transparent heating element. The semiconductive composition may be applied to substrates of quartz, ceramic, enamel, metal oxides, oxide coated metals and minerals. The heating composition may be used in quartz or glass chemical apparatus, in car, plane, or ship windows, in household dryers, refrigerators and household heating.

Title: Improvements in or relating to the manufacture of aldehydic compounds
IPC: C07C45/49
Filed: 1934-10-10
Abstract: In the production of aldehydes by reaction of carbon monoxide with a cyclic hydrocarbon or substituted hydrocarbon and aluminiumchloride under pressure, the reaction mixture is hydrolyzed by pouring it into water, the temperature of which is restricted to a limited extent, such as 10--60 DEG  C. instead of employing ice or ice water.  The hydrocarbon may be aromatic or cycloparaffinic, such as benzene, alkyl benzenes, naphthalene, anthracene, and cyclohexane; and derivatives such as chlorbenzene may also be used.  In an example, carbon monoxide is introduced at 68 atmospheres into an autoclave containing aluminium chloride and benzene which has been saturated at atmospheric pressure with hydrogen chloride, the temperature of reaction being 20--50 DEG  C. The reaction mass is discharged slowly into water which is maintained at 10--60 DEG  C. by circulating tap water through cooling coils.
