Title: Improvements in or relating to Hydraulic Rotary Pumps or Motors of the Externally Meshing Gear Wheel Type
IPC: F04C15/00
Filed: 1968-04-05
Abstract: 1,177,022. Rotary positive-displacement pumps and motors. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE S.I.G.M.A. April 5, 1968 [April 14, 1967], No.16400/68. Heading F1F. In a hydraulic rotary positive-displacement pump, or motor, of the externally-meshing gear-type, a pair of gears 4, 5, Fig.1, are fixed to shafts 8, 11, respectively, which are supported by roller, or ball, bearings 15 .. 16a lodged in two axially - movable wear-plates 12, 12a, chambers 24, 24a between packing rings 26, 27 and 26a, 27a being connected to the highpressure side of the meshing gear-teeth through axially-oriented passages 25, Fig.2, and (25a), Fig.3 (not shown), in the respective wear-plates so as to effect displacement of the latter towards the gears and abutments 17 .. 18a having axial distances d therebetween slightly exceeding the length l of the gears. The rings 27, 27a isolate the chambers 24, 24a from the shaft 8, leakage liquid in spaces 28, 28a being returned to an inlet, or outlet, orifice 9 on the low-pressure side of the meshing gear-teeth through passages (not shown). Spacing rings 29 .. 30a are provided for the bearings 15 .. 16a, which rings contain slots 33, 33a to facilitate escape of the leakage liquid and to give liquid in the chambers 24, 24a access to the ends of the shaft 11, respectively. Recesses 19 ... 20a in a central portion 1 of a casing are connected to the spaces 28, 28a by passages 31, 31a. To facilitate communication between the orifice 9 and the gear-tooth spaces, a groove 23 is provided in each wear-plate. As shown in Fig. 2, leakage of the working liquid e.g. oil, between each wear-plate and the gears occurs across a broad sector α and a narrower sector # as indicated by arrows # 1 , # 2 , # 4 , # 5  and also in the region of the meshing gear-teeth towards the respective grovoe 23 as indicated by arrows # 3 , and this improves the volumetric efficiency and reduces energy losses. A second embodiment, Fig. 5, differs from that shown in Figs. 1 and 2 chiefly in that the rings 27, 27a are replaced by packing rings 35, 35a, spaces 36, 36a associated therewith being connected to each other by passages 38, 39 in the shaft-8 and a passage 37 communicating with the orifice 9. Rings 40, 40a protect the packing rings aforesaid. Leakage across each wearplate differs in detail from that shown in Fig.2 and is described with reference to Fig. 6 (not shown). The bearings 15 .. 16a may be replaced by plain bearings, which are either formed by, or lodged within, the wear-plates. When operating as a motor, the working liquid is supplied to an orfice 10 and discharged through the orfice 9. The pump or motor shown is related to that disclosed in Specification 1,125, 574.

Title: Improvements relating to the recovery or production of oxygen-containing aliphatic compounds
IPC: C07C51/487
Filed: 1925-06-26
Abstract: 273,810. Dreyfus, H. June 26, 1925. Acetaldehyde ; acetic acid.-Waste or dilute acetic acid such as results from the manufacture of cellulose acetate is treated by a reduction process to yield acetaldehyde, which is separated and may then be converted into glacial acetic acid or other concentrated or anhydrous products. The reduction to acetaldehyde is effected by treating the dilute or waste acetic acid in the vapour form with hydrogen or gases containing hydrogen, with or without carbon monoxide, in the presence of catalysts or contact materials. Suitable reduction-promoting catalysts are metals such as nickel, iron, zinc, tin, lead, silver, platinum, palladium, and copper, but other contact materials, such as pumice, glass wool, and sodium chloride may also be used. It is preferred to use an excess of hydrogen. The acetaldehyde may be separated from the reaction products by fractional condensation. It may then be oxidized by known methods, with or without the use of catalysts, to yield glacial acetic acid, or alternatively it may be treated by the method of Specification 273,622 to yield keten and/or acetic acid and/or acetic anhydride. In an example, the vapours of acetic acid of 16-30 per cent strength are mixed with hydrogen and passed over finely divided nickel at 250-300‹ C. If a contact material, such as glass wool, is used instead of nickel, the reaction may be effected at a higher temperature, for instance 400‹ C. The Provisional Specification describes the use of carbon monoxide instead of hydrogen.

Abstract: 663,943. Induction heating. BIRLEC, Ltd. June 21, 1948 [June 20, 1947], No. 16576/48. Class 39(iii) A method and apparatus for produci n g homogeneous metal melts in multichamber induction furnaces includes the advancing of the outflow of molten metal from at least one melting channel, which opens into two of the several furnace chambers, into a section of one chamber where the influence of the electromagnetic field created in the channel is substantially less than at the channel outlet. A furnace having chambers 1, 2, interconnected by melting channels 3, 4, 5 threaded by transformer units 6, has one end of a refractory current conducting tube 13 within the channel 3 and the other end extending into a section of the chamber 2 which is substantially free from the electromagnetic field. A unidirectional flow of molten metal is thereby set up in each secondary loop formed by the channels 3, 4, 5 and the chambers 1, 2. The inclination of the tube 13, which may be of graphite, and the channels may be such as to allow the insertion of straight cleaning tools into the channels from openings 12 during furnace operation. An embodiment is described wherein similar unidirectional molten metal flows are produced in a three-chamber furnace. Specifications 611,549 and 632,947 are referred to.

Title: Dialdehyde polysaccharide-urea resin dispersions
IPC: D21H17/24
Filed: 1961-05-08
Abstract: A resin is produced as a stable aqueous dispersion by the interaction of a dialdehyde polysaccharide and urea in an aqueous medium at a pH of 5-8 and a temperature of 30 DEG -70 DEG C.  The urea may be added to a dialdehyde polysaccharide dispersion or the dialdehyde polysaccharide may be added to a urea solution.  The mole ratio of urea to dialhyde polysaccharide polymer unit may be 0,5-2,0.  The dialdehyde polysaccharide may be produced by the oxidation with periodic acid of maize or potato starch, dextran, algin, inulin, or cellulose.  Oxidation may be 50-100% complete. The required pH may be maintained by the presence of a buffer in a concentration of 0,1-1,0 N.  The buffer may be disodium phosphate, sodium bicarbonate, acetate, or p-toluene sulphonate, or triethanolamine.  The resin dispersion may be concentrated to a solid content of 50-90% by evaporation.  Gelling may be effected by acidifying and optionally heating.  The acid may be hydrochloric, sulphuric, phosphoric, formic, acetic, oxalic, citric, or lactic acid.  The gel may be dehydrated by drying or solvent exchange, e.g. with methanol.  The resin may be incorporated in paper, paint, printing ink, or textile material or form a coating, e.g. for washable wallpaper.  Examples are given. Specification 875,542 is referred to.
