Abstract: The servo-distributor is intended to be installed in the braking system of a tractor, including a distributor activated by the brake pedal to control braking. The servo-distributor comprises a hollow body (51) in which is provided a relay valve (92, 73a; 82, 97) controlled by the pressures in a control chamber (F, A) in such a way that, during braking, the relay valve (92, 73a; 82, 97) disconnects an outlet chamber (D) from an exhaust chamber (E) and connects a supply chamber (C) to the outlet chamber (D). Valve means (63, 64; 51b) operatively associated with the relay valve (73a, 92; 82, 97) are also provided in the supply chamber (C) and, during service braking, are intended to assume a first condition in which they allow communication between the supply connector (11) and the outlet connector (12) when the difference between the pressure in the control chamber (A; F) and the pressure in the outlet chamber (D) is less than a predetermined value, and a second condition in which they disconnect the outlet connector (12) from the supply connector (11) when the difference in pressure exceeds a predetermined value. By virtue of these characteristics, the servo-distributor also carries out the functions which, according to prior art, were performed by a supplementary so-called servo-diverter device.

Abstract: A process for the preparation of zirconium sulfate tetrahydrate. This process involves the leaching of a zirconium source with sulfuric acid and the formation of a zirconium sulfate tetrahydrate by the dilution of the slurry produced by the leach. The process further provides for the reconstitution of the acid diluted to produce the zirconium sulfate tetrahydrate once the zirconium sulfate tetrahydrate has been crystallised and removed from the diluted acid. The reconstituted acid is then recycled to the leach step. This process may include various purification techniques. The process allows for the preparation of zirconium sulfate tetrahydrate wherein waste sulfuric acid produced as a byproduct is minimized.

Inventor: FREGIEN GERT
IPC: H03K17/73
Filed: 1988-12-08
Granted: 1994-06-22
Abstract: In this method for controlling a gate-turn-off thyristor (1), the turn-off process occurs as usual by impressing a negative gate current (iG). To ensure improved utilisation of the gate-turn-off thyristor and of the driving driver stage (2), it is proposed to lower the negative driver voltage (UGKX) to a smaller value as soon as the anode current (iA) has dropped, that is to say as soon as the storage time (ts) has finished. The lowering can be effected in one step, in several steps or continuously after a delaying time function. The negative driver voltage is preferably lowered to a value of between 4V and 7V. The gate-cathode voltage (UGK) can be used for determining the precise time (t3) for lowering the voltage. The proposed voltage lowering reduces the power dissipation converted into heat in the thyristor which results in a distinctly reduced gate control power (PSt) and driver stage power (PTs). <IMAGE>

Title: Variable output oil pump
IPC: F04C2/10
Filed: 1988-03-03
Granted: 1991-12-18
Abstract: The invention provides a variable output pump of the gerotor type in which one rotor (16) meshes in two side by side annulii (14, 12) which can be aligned for maximum output and turned in opposite directions to be non-aligned for minimum output. The movement is effected by a gear train (20, 24, 29) displaced by a rack (40) which is hydraulically operated by pump pressure. Hence high pressure displaces the rack to result in lower output against lower pressure. A variation is described in which a control spool diverts fluid to either side of the piston according to need and this is displaced in one direction by the derived fluid pressure and in the other direction additionally by spring pressure transferred from the piston position by a lever system. This can give desired pump output/speed results at reduced power consumption.

Granted: 1992-05-13
Abstract: For treating sheet steel electrolytically galvanised on one side, the ungalvanised side is contacted with an aqueous pickling fluid which contains a hydroxycarboxylic acid and a peroxo compound. This method succeeds in removing extremely resistant mixed oxides, which lead to striped yellow or brown discolourations on the ungalvanised sheet steel surface of fine sheet electrolytically galvanised on one side. The fresh metal surface thus formed is at the same time passivated.

Title: Dust filter bag, production and use
IPC: B01D39/18
Filed: 1989-04-17
Granted: 1992-08-26
Abstract: The dust filter bag comprises a filter paper outer layer and a fine fibre non-woven fabric, each having characteristic specific properties. The fine fibre non-woven fabric can, if required, be reinforced by a supporting element. The combination of appropriate filter materials for the filter paper outer layer, the fine fibre non-woven fabric and the supporting element leads to high degrees of removal of fine dusts, and, at the same time, low air resistance and a low tendency to filter clogging. The multilayered filter bags can, according to the individual design, be manufactured on corresponding bag machines. The outstanding filtration properties allow the dust filter bags to be used for the removal of particles greater than or equal to 0.1  mu m in vacuum cleaners of the most diverse types, and also in the removal of toner by suction in copiers. Furthermore, the combination of the filter materials described in the form of flat filters, pleated filters, belt filters and roll filters is suitable for use in clean room technology, e.g. in semiconductor manufacture, film manufacture or in the hospital sector.
