Title: Remote positional control for hydraulic presses
Inventor: SALTER FRANK SIDNEY
IPC: F15B9/12
Filed: 1956-09-29
Abstract: 843,394. Fluid-pressure servomotor-control systems. LOEWY ENGINEERING CO. Ltd. Sept. 19, 1957 [Sept. 29, 1956], No. 29801/56. Class 135. An hydraulic servomotor system for the remote control of a forging press 10 having a crosshead 11 movable with respect to the press base 12 by an hydraulic ram under the control of a main control valve 20, comprises a servo valve 21 controlling the supply and exhaust of pressure liquid to and from cylinders 25, 25a to actuate a pair of opposed pistons 24, 24a in one or other direction which through a rocker or cam-shaft 22 raises and lowers valve elements of the main control valve. The servo valve 21 comprises a valve piston 105, 106 connected by a rod 26 to a shaft 71 mounting a sprocket 70 of remote control mechanism 40 and a follow-up sleeve 104 connected by linkage 27 to the shaft 22. The sprocket engages a pair of endless chains 55, 61 which when moving at the same rate rotate the sprocket without raising or lowering the rod 26 so that the servo valve is inoperative. The chain 62 is movable between stops 47, 47a, adjustable to correspond to the desired length of the stroke of the crosshead 11, by a manually-operable handle 65 whilst the chain 55 is moved by the crosshead 11 by means of a further endless chain 52 and sprockets 53, 54. To operate the press, the operator moves the handle 65 downwards along with the chain 62 and, since the chain 55 is at this time stationary, the sprocket 70 moves downwards besides rotating, and actuates the servo valve 21 and through it, the pistons 24, 24a, the main control valve 20 and the crosshead 11. The crosshead moving downwards then moves the chains 52, 55, and the downward movement of the sprocket 70 becomes a differential of the movement of the handle 65 and the crosshead 11. When the crosshead moves at a speed corresponding to that of the handle 65, downward movement of the sprocket 70 ceases so that the positions of the servo-valve and the main control valve are unchanged and the hydraulic pressure to the ram cylinder remains the same. A pointer 57 indicates the actual position of the crosshead and a pointer on the handle 65 the desired position of the crosshead. To limit the speed at which the operator may operate the press a device 90 controlled by a centrifugal governor 91, or a dashpot is connected to a sprocket 64 on the chain 62. An auxiliary hand control 80 to operate the servo valve 21, is provided. The mechanical differential mechanism constituted by the sprockets and chains may be replaced by an electrical differential which includes potentiometers whose movable elements are connected to a handle operable by the operator and the crosshead, and a Wheatstone bridge or other balance circuit.

Title: Improvements in the separation of sulphur oxides from waste gases
Inventor: HAMPERCHT GUENTHER
IPC: C01C1/247
Filed: 1960-08-31
Abstract: In the separation of sulphur oxides from waste gases by reaction of the gases with ammonia and water to form ammonium sulphite, which is oxidized in the presence of catalysts to ammonium sulphate, active carbon is used as the catalyst and the amount of ammonia is equivalent to or less than equivalent to the amount of oxides of sulphur.  The active carbon used is preferably that which has been activated by steam.  The O2-containing gas used for the oxidation may be the gas containing the oxides of sulphur or another gas, e.g. air. The reaction may be carried out, in a reaction tower containing filler bodies or baffles, at a temperature depending on the temperature of the sulphur oxide gases, but advantageously above 30 DEG C.  The waste gases may be practically free from water, so that they should be moistened with hot water or an appropriate mixture of steam and water, the moisture content being so adjusted that the reaction proceeds at a practically constant temperature and an (NH4)2SO4 solution of constant concentration is formed.  Loss of ammonia is avoided by limiting the NH3 addition to an amount necessary for the formation of an (NH4)2SO4 solution which has a pH value less than 6,8.

Title: Improvements in method for making shaped rubber articles
IPC: C08J5/02
Filed: 1930-10-11
Abstract: Rubber goods are manufactured by dipping a coated former into latex &c. dispersions.  The former is coated with a solution of a coagulant in a volatile organic solvent part of which is evaporated before dipping.  A mixture of a volatile organic solvent and a less volatile solvent may be used.  The solvent may be evaporated until a viscous or even a solid film of coagulant remains on the former.  If the solution is very fluid a viscous liquid such as glycerine or syrup or colloids such as gum arabic, a cellulose ester polymerized vinyl acetate, &c, may be added to increase the viscosity after evaporation, but in amounts insufficient to produce a solid coagulant film.  As examples of coagulants are a non-volatile acid, a coagulating salt or a mixture of the two.  As examples of salts are the salts of bivalent metals such as magnesium, the alkaline earths, zinc, copper, cobalt, cadmium, ferrous iron, lead, nickel, and manganese, of tri- and tetravalent metals such as aluminium, ferric iron, antimony, chromium, molybdenum, tin, thorium, vanadium, and zirconium.  In general the chlorides and nitrates are preferable but many other acid radicles may be used.  As volatile organic solvents are used methyl, ethyl or amyl alcohol, acetone, glycol or glycerine, ether, carbon disulphide, chloroform, ethyl formate or ethyl acetate. As less volatile solvents are used water, higher monohydric alcohols, water soluble esters, glycol or glycerine.  Where a coagulant is used such that it may form an insoluble hydroxide or oxide in an alkaline latex, an acid may be added to the coagulant to assist coagulation. In examples the coagulant solution consists of (1) 100 parts of hydrated calcium nitrate in 200 parts of acetone; (2) 100 parts anhydrous commercial calcium nitrate in 200 parts of acetone; (3) 40 parts of calcium chloride, 10 parts of lactic acid in 80 parts of methyl alcohol.  Further examples of coagulant solutions are 10 parts citric acid, 1 part glucose (corn syrup), 100 parts acetone; 10 parts zinc chloride or basic lead acetate, 40 parts methyl alcohol and either 10 parts isopropyl alcohol, 5 parts normal butyl alcohol or 2 parts ethylene glycol.  Specification 299,737, [Class 70, India-rubber &c.], is referred to.

Filed: 1965-07-19
Abstract: In making a dry powdered foodstuff, which is particularly suitable for babies and old or sick people, a mixture of unfinished, hulled rice, e.g. parboiled unfinished rice, and a p  very dilute acid, such as very dilute orthophosphoric or glycerophosphoric acid, is heated and digested at a constant supra-atmospheric pressure, e.g. for three hours at a pressure of two atmospheres, with continuous stirring, in a closed autoclave. The mixture may be heated to a temperature at which it would boil under normal atmospheric pressure.  The mixture is then allowed to cool, e.g. to room temperature, the autoclave is opened, and an aqueous alkaline solution, e.g. of sodium bicarbonate and/or sodium carbonate is added to neutralize the acidity.  The resulting mixture, e.g. having a pH between 5.5 and 6, is then vacuum-dried with moderate heating, and ground to a powder, e.g. in a hammer-mill.  The dry powdered foodstuff may contain 8% of water-soluble proteins, 85% of water-soluble carbohydrates, by weight, and an appreciable amount of phosphorus, e.g. in the form of phytine (calcium magnesium inositol hexaphosphate) derived mainly from the chaff and germ of the rice.  The foodstuff may be dissolved in water, milk, beer, soup or other potable liquid.
