Title: Metal plating
IPC: C23C18/54
Filed: 1965-06-10
Abstract: A metallic coating is provided on at least one electrically conductive substrate by tumbling in a tumbling barrel the substrate or substrates and a liquid (e.g. water) containing (i) ions of a dissolved salt of a plating metal; and (ii) particles of a driving metal or driving metal alloy, which driving metal is or which metals in the driving metal alloy are less noble than the plating metal: the pH of the liquid being such as will dissolve the driving metal or driving metal alloy during plating.  It is to be understood that the "driving" metal or metal alloy induces plating.  The tumbling barrel may be simultaneously rotated and axially reciprocated.  The examples illustrate various components which can be used in the tumbling barrel.  The plating metal (a), driving metal powder (b), and the object to be plated (c) are as follows:- .a.b.c. .I.Sn.Al.steel .II.Sn.Mn.steel .III.Sn.Mg.steel .IV.Sn.Ti.steel .V.Sn.Zn.steel .VI.Cd.Al.steel .VII.Pb.Zn.steel .a.b.c. .VIII.Hg.Zn.steel .IX.Ag.Zn.steel .X.Tl.Zn.steel .XI.Sn.Zn.Cu .XII.Sn.Zn.Mo .XIII.Sn.Zn.brass .XIV.Ni.Al.steel  The following are also given:- .a.b.c .Zn.Mg.Fe .Sn.Al.Zn plated part  Specified driving metals in alloy form are Al:Mn; Al:Zn and Sn:Al:Zn.  Glass beads may be used as impact media in the tumbling barrel.  Massive articles, small parts such as washers or flakes or granules may be plated.  Ferrous metal parts plated with Sn by the method may afterwards be plated mechanically or electrically with Zn or Cd.  A solid product to add to H2O to effect plating may comprise 1) a mixture of a plating metal salt, driving metal powder and means for preventing intimate contact of the salt and powder in the absence of water (e.g. 1 or 2 drops of diethanolamine or n-tallow or 1,3-propylene diamine) all pressed into a pellet or 2) the plating metal salt and gum-encased driving metal particles pressed into a single cake or incorporated in a textile or abrasive product.

Patent GB-1046514-A (GB)
Title: Dyeing process
Inventor: GUGERLI ULRICH
IPC: D06P1/00
Filed: 1963-06-11
Abstract: Dyeings and pigmentations, hereinafter termed colourations, are made conforming in colour closely to the colour of a given pattern which colour may alternatively be defined colorimetrically.  The process is performed by preparing a number of colourations that roughly match the pattern, using for this purpose n colourants, n being a positive integer.  Among the so-prepared colourations there must be at least n + 1 colourations whic which satisfy the condition that the determinant D is not zero where <FORM:1046514/D1-D2/1> where Cij is the concentration of the j-th colourant in the i-th colouration.  By optical measurement the colour differences between each colouration and the pattern are determined; alternatively at least n + 1 determinations are made of colourations which satisfy the above condition are so determined. From the measured colour differences the gradient of the colour difference in the concentration space at the centre of gravity of the concentration range under examination is calculated with approximate accuracy.  The n1 new colourant concentrations are determined by means of the formula <FORM:1046514/D1-D2/2> where C1j is a new concentration of the j-th colourant, oCj a concentration of the j-th colourant within the previously explored concentration range, gj the calculated j-th component of the gradient of the colour difference in the concentration space, D E the average colour difference of the measured colourations and f (D E) a function of the average colour difference which is adapted, on the basis of previous experience, to provide a maximum rate of convergence of the process for a specific type of matching problem.  The colourant concentrations thus calculated serve as the basis of a further approximate recipe.  This procedure is repeated until the match is sufficiently close.  In a modification of the above process the concentrations of the colourants used for a set of colourations which are prepared at each step of approximation are chosen in accordance with a 2n factorial design.  The process is applicable to the dyeing or printing of textile materials, films or sheets of aromatic polyesters, polyamides, cellulose esters, acrylic polymers or wool as well as the pigmentation of moulded shaped articles of plastics, rubber or resins and additionally in spin-dyeing.  Examples of colour-matching in wool dyeing and in the pigmentation of unsaturated polyester/styrene polymer glass fibre reinforced plates are given.

Abstract: 787,138. Washing furs. BOEHME FETTCHEMIE GES. Aug. 12, 1955 [Aug. 13, 1954], No. 23253/55. Class 76. Chrome-tanned pelts are contacted with an aqueous liquor containing a water-soluble complex-forming compound having a carboxyl, hydroxyl or phosphoric acid group and a lipophilic residue to remove chromium soaps from the wool or hair of said pelt. The lipophilic group preferably has 10-18 carbon atoms and a group conferring water solubility such as an acid sulphuric acid ester, a sulphonic acid or a polyalkylene oxide group, and the liquor may additionally contain a surface-active compound such as a conventional pelt washing agent, e.g. alkyl sulphates, alkyl sulphonates or alkyl benzene sulphonates. The pelt also may be washed subsequently with a conventional neutral pelt washing agent. Compounds referred to are water-soluble mono-esters of di- and poly-basic inorganic or organic acids (phosphoric, tartaric, citric) with higher molecular weight hyroxyl compounds, cycloaliphatic (naphthene) or aliphatic-aromatic (alkylphenols) alcohols and their alkoxylation products, or their sodium or ammonium salts; and the polycarboxylic acids formed by reaction of unsaturated fatty acids (oleic, linseed oil, soya oil fatty acids) with maleic acid; their salts and derivatives (by sulphonation or ethoxylation) may also be used if they contain at least one carboxyl group capable of complex formation. In the example, chrome tanned sheepskin fleeces were treated at 40-50‹ C. with a mixture of the sodium salts of monophosphoric acid esters of ethoxylated C 12 -C 18  alcohols and a sodium alkyl sulphate mixture. They were subsequently washed in an aqueous ammonium alkyl sulphate mixture.

Filed: 1931-08-26
Abstract: 381,670. Gauging-apparatus. DUNLOP, W. and COLMAN, Ltd., J. & J., Carrow Works, Norwich. Aug. 26, 1931, No. 23975. [Class 106 (ii).] Metal sheets to be sorted by gauging their thickness are passed between a pair of rollers one of which is movable at right-angles to the sheet, the movement closing a contact in an electric circuit associated with electromagnetically operated traps which divert plates of predetermined thickness. The sheets are fed from a table 5 at one end of the machine through one or more gauging stations set for decreasing thicknesses, the thin sheets being passed on to the next gauging station, and the sheets satisfying the gauge being delivered through a trap at each station ; sheets too thin for any gauge passing to a table 6 at the other end of the machine. On a shaft 7 driven by a belt pulley 8 are rollers 9 which support the plate and co-operate with rollers 10 on the other side of the plate to feed it forward. Also secured to the shaft 7 is a bevelled roller 11 opposite which on the other side of the plate is a similar gauging roller 13 carried at the lower end of a vertically movable rod 12 normally pressed down by a spring 14. This rod at the top is connected bv a short link to a movement multiplying linkage 15, 16a, 17 at the end of the last link or lever of which is a contact 18 adapted to engage a fixed spring contact 19. Slightly in advance of the rollers 13, 11 are small rollers 20a, 20b. At the level of the table 5 is a trap door 28a pivoted at 27 and normally flush with the table level to allow a plate to pass over it. During passage of the plates, when the roller 13 is lifted sufficiently to cause the contacts 18, 19 to engage, an electric circuit is partly made, but to avoid the presence of a rough edge actuating the device, the circuit is not completed until the plate engages the roller 20a when the circuits of solenoids 22, one at each side of the machine, are made and the trap door 28a is operated through lever linkages 24, 25, 26 to allow the plate to fall into a corresponding receptacle. Thin plates pass on to a feed roller on the shaft 30b and hence to a second set of gauging rollers and so to the delivery rollers 36a. The shafts 7, 30b, 33 and the spindle of the delivery rollers are interconnected by chain gears.
