Patent ES-436871-A1 (ES)
Title: Mortar bomb with double wall enclosing fragments - has inner wall with welded stabilising flanges for holding fragments
IPC: F42B12/32
Filed: 1975-04-23
Abstract: The mortar bomb shell has an outside and inside casing and the space between these walls is filled with balls embedded into rubber or plastics. These balls form the effective fragments and they are firmly held also by a thin walled inner lining. This arrangement provides an optimised stable lightweight bomb which can be fired over longer distances from a relatively lightweight mortar. The inner lining sections have outwards folded flanges which contact the inner wall of the outer casing either directly or by means of a thin flexible layer. The flat flange faces are welded together and hence the edge of the rib formed is in contact with the outer casing wall at its maximum girth.

Title: Treatment of zinc plant residue
IPC: C22B7/00
Filed: 1975-09-12
Abstract: A process for the treatment of zinc plant residue formed on leaching zinc calcine with sulphuric acid in which the residue is leached in a first leaching step with a sulphuric acid solution at atmospheric pressure, and a temperature above about 60 DEG C, in the presence of excess zinc sulphide reductant whereby ferric iron in the residue is reduced to the ferrous state, thereby forming a zinc sulphate solution containing excess acid, ferrous iron and other dissolved impurities such as germanium, indium, gallium, antimony and arsenic nd a mixture of solids containing undigested zinc residue, lead residue, and unreacted zinc sulphide. Clarified solution is separated, preferably by thickening, from the mixture of solids. The mixture of solids is leached in a second residue leaching step at atmospheric pressure and at a temperature above about 60 DEG C in a solution which is substantially higher in acid than the solution in the first leaching step, unreacted zinc sulphide from the first residue leaching step providing reducing conditions in the second residue leaching step. Slurry from the second residue leaching step is treated by flotation to separate a froth product comprising unreacted zinc sulphide and elemental sulphur, a tailings product containing gangue and a lead residue, and an acidic solution which is recycled to the first residue leaching step. A portion of the clarified zinc sulphate solution from the first residue leaching step is treated by oxidizing a small part of the ferrous iron contained therein, and neutralizing this portion of the solution with limerock to precipitate solids containing oxidized iron, gypsum, and the other impurities. These precipitated solids are separated and this portion of the solution is combined with the remainder of the clarified zinc sulphate solution. Ferrous iron in the combined solution is oxidized to precipitate ferric iron compounds which are separated from the solution to provide purified zinc sulphate solution which is recovered.

Title: Servo-assisted hydraulic master cylinder
IPC: B60T11/20
Filed: 1977-05-19
Abstract: A servo-assisted hydraulic master cylinder has a variable ratio effect so that brake fluid is initially displaced to the brakes at a high rate with respect to driver pedal movement and then at a low rate when an appropriate pressure has developed.

Title: Centrifuge with automatic sludge discharge
IPC: B04B1/14
