IPC: F03B13/18
Filed: 1921-07-22
Abstract: 190,743. Stodder, E. D. July 22, 1921. Wave energy, utilizing.-In wave motors of the type in which the motion of a float acted on by the waves is transmitted to converting-mechanism, such as pumps, the upward and downward movement of the float actuate separate convertors, those actuated by the upward movement being of greater capacity than those actuated by the downward movement. Between the columns of a pile are arranged floats B, sufficient space being allowed to permit movement in all directions. To each corner of each float B is connected a cable D, Figs. 1 and 8, the upper part of which is wrapped around a drum J and is counterweighted at F. Similar cables D<1> are connected to the lower corners of the float B and passing around sheaves E mounted on rings Z' are wrapped around drums J<2>. Each of the drums J, J<2> is converted through ratchet gearing to pumps so that the drums J drive their pumps on a downward movement of the float while the drums J<2> drive them during an upward movement, the pumps driven by the drums J<2> being of greater capacity than those driven by the drum J. In order to adjust the apparatus according to the intensity of the waves, each of the drums drives a series of pumps which may bn clutched to the drums in anv combination. To prevent the floats from striking against the columns X, Fig. 10, they are attached to chains C passing around collars Z mounted to slide on the columns. To each of these collars are attached cables d passing around sheaves e mounted on a fixed ring on the column X and carrying counterweights f.

Abstract: 1,224,030. Porous vitreous shapes. WASAGCHEMIE A.G. 26 April, 1968 [26 April, 1967], No. 19953/68. Heading C1M. Porous vitreous shapes are made by dissolving pulverulent material of a silicate and/or oxide nature in an aqueous solution of an alkali metal silicate, the proportion of the material being within the range of from 0.02 to 0.8 part by weight per 1 part by weight of alkali metal silicate, assisting solution of the pulverulent material either (a) by subjecting it to wet grinding in the solution, or (b) by blowing the pulverulent material on to the surface of the solution moving at such a velocity as to prevent or greatly reduce the piling up of the particles on the surface, or by using methods (a) and (b) simultaneously, drying the resulting product to drive off free water, disintegrating the dried product to a particle size within the range of from 0.001 to 10 millimetres, if it does not already have a particle size within that range, heating the resulting product in a shaped condition at a temperature within the range of from 650‹ to 1000‹ C. to obtain a foamed product, and then cooling. Method (b) may be carried out by impelling the solution by means of a propeller stirrer situated within an open-ended passage below the level of the solution in the vessel so as to cause the solution and solid material suspended therein to circulate continuously in one direction through the passage and in the reverse direction in a space outside the passage. The pulverulent material may comprise one or more silicate and/or one or metal oxides such as zinc oxide, glass powder, aluminium oxide feldspar and lead dioxide. Calcium metaborate may be added. In an example, 30 litres of water glass is diluted into 30 litres of water and 50 grams sugar, 125 gms. zinc sulphate and 1000 gms. borax are dissolved. A mixture of 1-5 kg. of zinc oxide; 1À2 kg. of calcium metaborate, 0À2 kg. of aluminium oxide; 1.5 kg. of feldspar and 2À5 kg. of cullet powder is blown on to the rapidly moving surface of the solution pumped through a grinding mill or refiner. After evaporation and drying, the product is foamed in moulds or on a travelling band.

Title: Isoxazolidone derivatives and a process for the manufacture thereof
Filed: 1956-06-28
Abstract: The invention comprises DL-5-alkyl-4-aminoisoxazolidones-(3), and the preparation thereof and of 4-aminoisoxazolidone-(3) itself by esterifying an a -amino-b -hydroxypropiohydroxamic acid derivative of the general formula: <FORM:0795459/IV (b)/1> (wherein R represents hydrogen or an alkyl group, R1 represents an aralkyl group and X represents benzyloxycarbonyl) with an aromatic or aliphatic sulphonic acid halide, hydrogenolysing the resulting ester and treating the resulting hydroxamic acid with a basic agent.  The esterification step is advantageously carried out in the presence of a tertiary base with or without an inert solvent, and the hydrogenolysis step by means of catalytically activated hydrogen or an alkali-metal in liquid ammonia, whilst the basic agent in the third step may be an alkali metal alkoxide, hydroxide or carbonate, gaseous ammonia, an organic base or a basic exchange-resin, suitably in aqueous or alcoholic solution.  The second and third steps may be combined by hydrogenating the esterification mixture in the presence of an alkali metal alkoxide in alcoholic solution or, when using an alkali metal in liquid ammonia in the second step, the liquid ammonia may be evaporated and water added to form with the remaining alkali metal the hydroxide thereof which acts as the basic agent.  In examples: (1) DL - a  - benzyloxycarbonylamino - b  - hydroxypropiohydroxamic acid O-benzyl ether is esterified with p-toluene-sulphonic acid chloride and pyridine, the product is suspended in ethanol and hydrogenated in the presence of palladium, after which a solution of sodium methoxide in ethanol is added and the mixture warmed to produce 4-aminoisoxazolidone-(3); alternatively the sodium methoxide solution is added to the esterification product and the hydrogenolysis is effected in the presence thereof, or the esterification product is dissolved in liquid ammonia, sodium is added until a blue coloration persists, the ammonia is then allowed to evaporate and the residue dissolved in water, or hydrogenation of the esterification product is effected in aqueous alcoholic hydrobromic acid solution, and a stream of dry NH3 is then passed in; (2) DL-a -benzyloxycarbonylamino - b  - hydroxybutyro-hydroxamic acid O-benzyl ether is esterified with methanesulphonic acid chloride and pyridine and the product is subjected to the last of the four alternative treatments in (1), giving DL-4-amino-5-methylisoxazolidone-(3).  Specification 795,458 is referred to.

Abstract: 1388874 Rod and wire strainers R B DE VALENZUELA 1 May 1972 [8 Feb 1972] 20066/72 Heading F2G [Also in Division E2] A device for the anchorage to a traction jack of reinforcements to be post-tensioned comprises a hollow truncated conical wedge 1 having a wall of uniform thickness, the inner surface of which is provided with longitudinally-extending grooves (not shown) distributed equidistantly therein and the exterior surface of which is provided with channels (not shown) in radial alignment with the grooves, and a ring 4, having a tapered bore which corresponds to the exterior surface of the wedge and channels (not shown) which are formed in the tapered bore to correspond and act, in conjunction with the channels formed in the wedge 1, to grip the terminals of rods or cables 5 located therebetween. The ring 4 connects with a cylinder 3 having a chamber 6 into which ends of the rods or cables 5 extend and having a chamber 7 which connects to the chamber 6. A stepped piston 2, having the wedge 1 mounted thereon, is slidable in the cylinder 3 and is urged towards the ring 4 when pressurized-fluid enters an opening 9 in the cylinder. This causes gripping of the rods or cables between the channels of the wedge 1 and the ring 4. Release is effected when the pressurized-fluid is directed to an opening 10 in the cylinder and disconnected from the opening 9, the piston 2 being returned and fluid escaping through said opening 9.
