Title: Process for the preparation of phosphoric acid
IPC: C01B25/232
Filed: 1968-05-16
Abstract: Phosphoric acid and gypsum are produced from calcium phosphate or phosphate rock by mixing with sulphuric acid and at least one alkali metal salt and/or amorphous silica (which term includes some silicates) in an amount which is at most 30% by weight of the dry calcium phosphate or phosphate rock and which satisfies the equation where [M 2 O] is the weight per cent of alkali metal present calculated as oxide, [SiO 2 ] is the weight per cent of amorphous silica (including that as silicate) present, and [CaF 2 ] is the weight per cent of fluorine present calculated as calcium fluoride, all weight per cents being based on the weight of the dry calcium phosphate or phosphate rock heating the resultant mixture at 100 to 300 C. and, if necessary, forming it mechanically before, during or after heating to form solid non-disintegrable small masses from which the phosphoric acid is extracted to leave gypsum. The alkali metal salt and/or silica may be added to the phosphate, before it is crushed, before the sulphuric acid is added, or as the sulphuric acid is added. The alkali metal salts named are the halides, sulphates, nitrates, carbonates, phosphates, hydroxides, oxides, sulphides and silicates of lithium, sodium, and potassium, sodium acetate, sodium citrate, and potassium oxalate. Amorphous "silicas" named are silica hydrogel and xerogel, alumina/silica mixture, calcium oxide/silica mixture, calcium silicate, magnesia/silica mixture, magnesium silicate and alkali metal silicate. The recommended amount of sulphuric acid is 0.8 to 1À2 the amount that is equivalent to all the metals present in the reaction mixture. The preferred size of the small masses is to 50 mm. and the phosphoric acid may be extracted by any known method, but it is preferred to extract it with water, or aqueous phosphoric acid which has been formed by extraction with water of pellets that had already been extracted with phosphoric acid to produce more concentrated acid.

Title: Method of manufacturing electrochemical generators
IPC: H01M6/08
Filed: 1968-12-07
Abstract: A process for making an electrode comprising a cup having active material on the walls thereof, comprises introducing a rod-like mandrel into the cup, distributing pulverulent active material in the annular space between the mandrel and the cup, compressing the active material to render it mechanically cohesive and removing the mandrel from the cup. The cup may be of zinc and the active material may be dry amalgamated zinc powder. Compression of the active material is achieved by reducing the diameter of the cup. This may be achieved by passing the cup through a reducing ring of slightly smaller diameter than the cup or by using the apparatus shown in Figs. 15 and 16 where Fig. 16 is a cross-section taken at BB. Cup 1 containing active material 5 and mandrel 22 is compressed by the sectors 32 of tapered split ring 31 when member 33 with a hole of equal taper is moved upwards wedging the sectors together as shown in Figs. 15 and 16 compressing the cup by a radial force only. When the cup has been compressed member 33 is lowered allowing springs 35 to open the split ring so that the cup can be removed. Assembly of the cell is completed after removal of the mandrel by insertion of a depolarizing dolly and carbon rod electrode, the addition of electrolyte and a further reduction in the diameter of the cell.

Patent ES-437680-A1 (ES)
Title: Position-responsive hydraulic cylinder
IPC: F15B9/08
Filed: 1975-05-14
Abstract: A double acting hydraulic cylinder with integral valves is described wherein rod extension is directly proportional to positioning of a control level. A change in the control lever to a certain setting causes an integral control valve to move to either side of a neutral position to selectively connect the cylinder chambers to the source or reservoir and thus to cause movement of the rod. In response to rod movement, a threaded feedback means causes movement of the valve such that, when the desired position of the rod is reached, the valve is returned to the neutral position. With the aid of an integral float valve, the control lever can be placed at a maximum or minimum setting and both chambers will be connected to the reservoir such that the position of the rod would be dependent on external forces on the rod.
