Title: Pigments and process for their production
IPC: C09B67/00
Filed: 1973-05-16
Abstract: 1440591 Polyamides as pigment carriers for incorporation into polymers DAY-GLO COLOR CORP 16 May 1973 [17 May 1972] 23258/73 Addition to 1383051 Headings C3P and C3R [Also in Division C4] A pigment comprises a colouring material and a linear polyamide carrier. This polyamide is the condensation product of an aliphatic polyfunctional primary amine, an alicyclic polyfunctional primary amine or a heterocyclic secondary diamine (a), a monocarboxylic acid (b), and a polybasic acid (c), which is either a polybasic aliphatic acid or a mixture of an aliphatic acid and a polybasic aromatic acid with carboxy groups on non-contiguous carbon atoms. The mole ratio a : b : c is from 10 : 1 : 10 to 1 : 1 : the average molecular weight is 400 to 2500, and most of the molecules have at least one free carboxy group. The pigment may be made by incorporating the colouring material in the polyamide, and reducing the product to particulate form. The polyamide, may include a stabilizer, which may be a salt of an organic acid or an oxide or carbonate of an element of Group IIA or IIB. The colouring material may be a fluorescent dye. The pigment may be incorporated in inks, paints and mouldable resins, e.g. moulding compositions based on polyolefines or polyvinyl chloride or vinyl plastisols.

Class 38 (iv). A welding arc, particularly one operating in a gas shield and supplied from, say, a lowfrequency transformer 1, is struck and stabilized by high-frequency current supplied by a crystalcontrolled valve generator into the welding line 12 by a step-down transformer 10 which matches the arc resistance to the resistance required by the generator for transference of maximum power, the length of the welding line being, say, between one eighth and one quarter (or an odd multiple thereof) of the wavelength of the highfrequency oscillation so as to ensure adequate striking voltage at the electrodes. The highfrequency return path may be in part formed by the work lead 7 and in part via earth and condenser 22. Alternatively, a separate return lead, forming with the welding line 12 a transmission line of characteristic impedance of between 100 and 300 ohms, may be employed. Condensers 20, 21, 26 may tune the windings of transformer 10.
