Title: Compositions and processes for conditioning the surface of formed metal articles
Inventor: AWAD SAMI B
IPC: C10M107/34
Filed: 1991-03-13
Abstract: Articles such as aluminium cans, after forming and cleaning, are surface-conditioned to enhance their mobility in subsequent automatic handling operations by treatment while still wet from pre-cleaning with a multi-component aqueous composition containing certain water-soluble ethoxylated phosphate derivatives of general formula (I), water soluble Fe, Zr, Sn, Al or Co salts, water-soluble metal-etchants and other ethoxylated organic derivatives of general formulae (II) and (III). Preferably the compositions also include further components, namely chelating agents for the metal salts and/or still further ethoxylated organic derivatives of general formula (IV). The compositions may be operated at relatively acidic pH values where they are spared microbiological degradation, but preferably will nevertheless include an effective amount of biocide and/or anti-foaming agent. The results achieved are better than in the state of the art - in particular the compositions may be made up with tap water rather than deionized water, the treatment tends to remove spotting resulting from unplanned production stoppages, and the treated surfaces are notably free from "water-breaks". In formula (I) each of R<1> R<3> and R<6>, which may be the same or different, is hydrogen or an alkyl group (C1-4), each of x, y, z is zero or an integer from 1 to 25 and each of R<2>, R<4> and R<5>, which may be the same or different, is hydrogen or a monovalent cation or a monovalent fraction of a polyvalent cation or an alkyl, aryl, or arylalkyl group (C1-20), provided that at least one of R<2>, R<4>, R<5> (i) is not hydrogen and ii) has at least one alkoxy group interposed between it and the -phosphorus atom. In formula (II) R<7> is a linearal cyclic or branched monovalent aliphatic hydrocarbon moiety (C1-25), X is hydrogen, halogen, phenyl or R<1>, and S = 150; and in formula (III) R<8> is a linear, cyclic or branched saturated monovalent aliphatic hydrocarbon moiety (C4-25), and (C6 H4) is an ortho-, meta-, para-phenylene nucleus. In a second aspect metal surfaces are treated with a surface-conditioning composition based on water-soluble ethoxylated organic materials incorporating also a biocide, eg hydrogen peroxide, and/or an anti-foaming agent. <IMAGE>

Title: Controller of hydraulic driving machine
Inventor: TAKAMURA FUJITOSHI
IPC: F15B11/08
Filed: 1993-09-07
Abstract: A controller of a hydraulic driving machine for controlling preferentially one working machine to other machines. The same operation quantity of a plurality of operation levers (3, 4) is weighted in accordance with the kind of works (M1 to M5), and the weight is stored in a memory of a controller in such a manner as to correspond to the kind of the operation levers (3, 4) and to the kind of the works. On the other hand, a switch (2) selects the kind of the works (M1 to M5). The operation levers (3 and 4) are operated, and when the switch (2) selects the kind of the works, the weight corresponding to the kind of the selected operation levers (3, 4) and the selected kind of the works (M1, M2) are read out from the memory, and the weight thus read out is added to the operation quantities (S1, S2) of the operated operation levers (3, 4). Then, signals (E, E') representing the operation quantities, to which the weight is added, but not the signals representing the open quantities (S1, S2) of the operation levers (3, 4) themselves, are outputted to a control valve (7). The present invention can control one working machine more preferentially to other machines by merely adding an apparatus having a simple construction to an existing hydraulic circuit. Accordingly, the cost of the apparatus can be drastically reduced. <IMAGE>
