Abstract: 526,550. Softening agents ; treating textiles with liquids. GEIGY AKT.-GES., J. R. March 20, 1939, No. 8807. Convention date, Feb. 8. [Classes 2 (iii) and 15 (ii)] Soluble salts of derivatives of hydroxybenzenecarboxylic acids having the general formula where n stands for 1 or 2 and R stands for an aliphatic or alicyclic radical having more than ten carbon atoms are manufactured by causing a chloromethyl substitution product of a hydroxy-carboxylic acid of the benzene series or of the corresponding acid anhydride to react with an aliphatic or alicyclic alcohol having more than 10 carbon atoms and converting the product into a soluble salt by neutralization. The products are used for softening natural and regenerated cellulose and may be applied together with direct dyestuffs. The condensation is carried out in an organic solvent such as benzene or chlorobenzene. In the examples (1) viscose yarn is dyed with diphenyl blue black GHS with the addition of the sodium salt of 5-octadecyloxymethyl-2-hydroxybenzoic acid ; (2) a padding machine is charged with a solution of the sodium salt of 5-octadecyl-oxymethyl-2- hydroxybenzoic acid, and cotton goods are treated therein, pressed and dried; 5-octadecyloxymethyl-2-hydroxybenzoic acid is prepared by condensing stearyl alcohol and 5-chloromethyl-2-hydroxybenzene-1- carboxylic acid ; similar compounds can be obtained by using 5-chloromethyl-2-hydroxy-3-methylbenzoic acid or 3-chloromethyl-2-hydroxy-5- methylbenzoic acid and cetyl alcohol or oleylalcohol or by condensing 3:5-di(chloromethyl) 2-hydroxybenzoic acid with dodecyl alcohol. Instead of the above alcohols mixtures which are obtained by the reduction of vegetable or animal fats, of resins, or of waxes or naphthenic acids may be used. Halogen substituted chloromethyl compounds, for example, 5- chloromethyl-3-chloro-2-hydroxybenzoic acid, may be used. Specification 17118/99, [Class 81], is referred to.

Abstract: 1482044 Coating by laser fusion CATERPILLAR TRACTOR CO 4 March 1975 [4 March 1974 24 Jan 1975] 8882/75 Headings B2E and B2L [Also in Divisions C7 and Fl] A method of fusibly bonding a solid powder to a metal article comprises, (i) depositing a band of powder onto the article, (ii) melting the coating material by focussing a continuous wave laser beam thereon and (iii) subsequently removing the focussed beam to allow the coating material to cool and solidify, thereby providing a fused coating with a thin interstitial bond between it and the metal article. In a preferred embodiment, a rotatable disc 20 is mounted on an oblique plate 18 and removably receives the face of an austenitic chrome nickel silicon steel valve 14 from an internal combustion engine. A chromium/cobalt alloy powder is fed through a tube 34 whose nozzle 38 is so close to the valve seat 26 that powder is deposited only when the valve is rotated. The part of the valve seat adjacent the nozzle remains horizontal by virtue of the obliquity of the plate 18. On rotation of the valve, the powder is moved into the path of a focussed laser beam 50 directed onto the valve seat by a universally mounted mirror 40, and melts but solidifies immediately on leaving path of the beam. In an alternative embodiment the powder is mixed with a temporary binder and deposited as a ring on the valve seat which is similarly rotated beneath the beam. The beam is preferably of annular shape.

Title: Apparatus and method of making a trimetal bearing material
IPC: B22F7/04
Filed: 1964-04-09
Abstract: A continuous strip of metal including a layer 34 of white metal, Fig. 2 (not shown), for cutting and bending to make bearings, is produced by passing a strip 10, e.g. of steel bearing a sintered copper alloy layer 25, through an entrance 42, Fig. 3 (not shown), into a housing 39, in which liquid white metal is fed from holes 94 in a trough 93 and solidified on the travelling strip 10 before the latter passes from the housing exit 43, Fig. 4 (not shown).  To prevent the liquid metal (92 1/2 % lead, 3 1/2 % antimony and 4% tin) from flowing off the strip, its edges are gripped between knife edges 71, 74, Fig. 5 (not shown), formed respectively on edges of pairs of side rails 63, 73.  To prevent the metal flowing along the strip to the housing entrance or exit, the knife edges 71, 74 have slight upward inclines 70, 70b, Fig. 3 (not shown), from a lowermost point 70a so that the strip has corresponding inclines.  The rails 63, 73 are adjustable vertically and for width of strip and their ends nearer the exit 43 can be raised or lowered slightly by rotation of a threaded bolt 89. The liquid metal is solidified, for bonding to the sintered copper alloy, by water (from jets 118 below the strip) deflected by a pivoted plate 115 against the underface of the strip.  Steel strip 10 to be coated passes from a reel 11, Fig. 1 (not shown), through a squaring shear 12 and a welder 13 (for joining successive strips) to apparatus 16 where a mixture of copper and bronze powders is deposited on the strip.  It then passes into a furnace 21 (having a reducing atmosphere of H2, CO and N2 supplied by a gas generator 22) to form the layer 25 of sintered copper alloy before entering apparatus 30 with its housing 39, Figs. 3-5 (not shown).  The reducing atmosphere passes into the housing 39 through the strip entrance 42 from the furnace 21 while a vertical flange 84 and baffles 128, Fig. 4 (not shown), extending across between the rails 63, 73, minimize air entry near the exit 43.  The strip is moved through the apparatus by a leveller 15 and rollers 26, Fig. 1 (not shown). There are adjustable levelling rolls 110, 124 and locating rolls 131, 132, Figs. 3, 4 (not shown).  Rolling.  Rolls 37, 38, Figs. 3 and 7 (not shown), compress the steel strip 10 with its sintered copper alloy layer and the upper roll 37 has bearings 96 which can ride up against springs 99 whose compression is adjusted by screws 101.
