Title: Antistatically treated paper
IPC: D21H19/38
Filed: 1974-07-31
Abstract: 1456885 Anti-static coatings WIGGINS TEAPE Ltd 16 July 1975 [31 July 1974] 33741/74 Heading B2E  Sheet material, having a synthetic polymeric surface, is coated with an antistatic agent comprising a synthetic hectorite clay having a layered structure wherein the layers carry an electric charge. The sheet material may be a paper material or a heat-consolidated web comprising or consisting of fibres of synthetic polymer. The material is coated on one or both surfaces with a layer of synthetic polymer e.g. polyethylene, and is for use as a substrate for receiving a radiation-sensitive coating for photographic purposes. The antistatic agent comprises synthetic hectorite day, being a compound having a magnesium silicate lattice structure containing magnesium ions bound to hydroxyl ions, some of which may be replaced 'by fluoride. Some of the magnesium ions are replaced by lithium ions or are absent from the lattice structure and/or some silicon atoms are replaced by e.g. Al, Sn, Zn or Ti atoms, which causes the formation of an electrically charged layer structure; in the presence of water exchangeable sodium ions disposed between the layers and balancing the charges on the layers, become hydrated, leaving charged layers which repel each other so that the hectorite clay forms a colloidal sol in the water. The antistatic agent may be present in a size coating on the paper base, under the polymeric material layer, or may be a backcoat on the polymer-coated sheet. Alternatively, the antistatic agent may be a coating over the polymeric coating. The antistatic coating may include sodium sulphate, a binder such as carboxymethylcellulose, starch or gelatine, colloidal or particulate silica, and a wetting agent. When applied over the polymer surface, the latter is preferably first subjected to a corona discharge treatment to promote adhesion of the antistatic agent. The antistatic composition is applied as an aqueous colloidal solution, subsequently dried. The polymer layer may be applied by extrusion coating. The treated base may be given a further coat of conventional radiation (light)-sensitive emulsion of gelatine containing selenium sulphide, zinc sulphide or cadmium sulphide (if necessary for adhesion, after application of a suitable sub-coat), to give a sheet material for use in chemical transfer photographic processes.

Title: Device for controlling the draught in boiler furnaces
IPC: F23L17/16
Filed: 1931-12-07
Abstract: 388,152. Regulating draught in boiler furnaces. THORNTON, A. A., 7, Essex Street, Strand, London.-(Mineralochemie Akt.-Ges. f³r Metallurgische und Chemische Produkte; 23, Wiedener Hauptstrasse, Vienna.) Dec. 7, 1931, No. 33871. [Class 51 (i).] In boiler furnaces more particularly for locomotives having a blower, fluid-injecting nozzles in the firebox, a valve connected with a supply of fluid under pressure and connected to the blower and injecting nozzles and also controlled in conformity with the throttle valve, manually operated means are provided for controlling the operation of the valve independently of the throttle valve and of the furnace door operating means. As shown in Fig. 1, a valve 3 to which steam may be supplied from the boiler or other source through a connection 73, or compressed air supplied by a connection 78, may be retained on its seat by a hand-lever 10 or released when it is desired to permit its opening by steam or other fluid pressure acting on the piston 11. When the valve 3 is in its closed position and the throttle valve of the engine is also closed, steam passes from the back of the valve 3 through pipe 16 to the chamber 28, Figs. 3 and 4, of a rotary control valve 22 operated in conformity with the throttle valve lever a. From the chamber 28 steam passes through holes 37, 38 in the valve through a tapered slot 36 and hole 35 respectively in a plate 24 to chambers 29, 31 in the valve casing and thence through a pipe 40<1> to the injector nozzle in the firebox and through pipe 18 to the back of the piston 11 ; a part of the steam also passes from the chamber 29 through an opening 33 in the plate 24, port 39 in the valve, and opening 34 in the plate to the pipe 17 and chamber 4 between the valve 3 and piston 11 from which it passes through a port 5 to the blower. When it is desired to increase the supply of steam to the blower and injector with the throttle valve closed, the lever 10 is operated to permit the valve 3 to be lifted by the steam pressure acting on the piston through the pipe 18 and steam then flows direct from the pipe 73 to the chamber 4 and thence to the blower and through the pipe 18 and ports and chambers in the control valve to the injector in the firebox. When the throttle valve of the engine is opened by rotating the lever a and control valve 22 anticlockwise, the port 37 in the control valve moves opposite to wider portions of the slot 36 and more steam is supplied to the injecting nozzles in the firebox while the steam supply to the blower is gradually shut off by the port 39 being closed by the plate 24. The supply of steam to the back of the piston 11 is also cut off by the closure of the port 35 in the plate 24. Instead of the rotary valve 22 a reciprocating valve may be employed.

Patent GB-625101-A (GB)
Title: Improvements in lubricating oils
Filed: 1945-12-14
Abstract: Mineral lubricating oils containing small amounts of fatty acids having an iodine number of from 10 to 15 are blown with a current of air heated to a temperature at which the fatty acids are molten so that partial oxidation of the fatty acids takes place within the body of the oil itself.  Mineral lubricating oils thus treated can be cooled to low temperatures without precipitation of fatty acid.  A mixture of fatty acids having the required iodine value may consist of stearic, palmitic and oleic acids.  In an example, a current of air heated to 100 DEG  C. is passed for from 15 to 20 hours through a petroleum spindle oil composition containing palm oil fatty acids and oleic acid.  The Specification as open to inspection under Sect. 91 refers to the stabilization of mineral oil containing saturated long chain fatty acid against cold by the addition of inhibiting substances. Suitable inhibiting substances are oxidized fatty acids or fatty acids isomorphous with those already present in the mineral oil. In an example, palm oil fatty acids and stearic acid are added to mineral oil.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to process for purifying oils and for converting heavy, incombustible oils into homogeneous fuels
IPC: C10G31/06
Filed: 1931-12-12
Abstract: Heavy fuel oils, e.g. residual tar oils and gas oils, are purified and rendered fit for use in burners and with Diesel or semi-Diesel engines by heating slowly to and maintaining a temperature of 50-100 DEG  C. whereby impurities rise to the surface, abruptly cooling the surface so as to form a film which sinks through the oil, and separating the oil and deposit.  Preferably 5-20 per cent of an oil complemental to that treated is added, e.g. an oil rich in volatile hydrocarbons to one void of such.  In an example, 85 kg. of residual tar oil from coke ovens is slowly warmed to 30 DEG  C. by a closed steam coil, 15 kg. of gas oil is added, and the temperature raised to 80 DEG  C. in 4 hours and maintained for 4 hours; the upper layer is cooled by a cold water coil, the mass allowed to settle for 40 hours, and the oil is decanted; the residual 10 kg. may be settled longer, and a further 5 kg. of oil decanted.  The process is especially applicable to residual oils obtained as described in Specification 389,203.
