Process for dyeing polyvinyl chloride

Shaped articles of polyvinyl chloride having a syndiotactic index higher than 2 (fully defined) are dyed with an aqueous dyebath containing a dissolved or dispersed dye either at a temperature above 100 DEG C. and at superatmospheric pressure or at the boil in the presence of a carrier. The polyvinyl chloride may be a copolymer containing at least 85% vinyl chloride units. Suitable carriers are listed. Examples of dyeing fibres are given.

A process for dyeing polyolefine or polyvinylidene chloride filaments

Polyolefine or polyvinylidene chloride filaments are dyed with a monoazo dyestuff, the aromatic nucleus or nuclei of which is or are substituted by one or more straight- or branched-aliphatic side-chains with at least seven carbon atoms. The dye may be applied from aqueous suspension, or may be produced in situ by applying, separately and successively, the diazotized amine and the coupling component and then effecting coupling on the fibre. The dyestuffs employed in the examples are: (1) p-cetyl-aniline --> p-nonyl phenol, formed on the fibre; (2) p-amino-octyl-benzene --> b -naphthol, applied from aqueous suspension; (3) p-cetyl-aniline --> p-cetyl-phenol, applied from aqueous suspension; and (4) p-octadecyl-aniline --> b -naphthol, applied from aqueous suspension.

The mixed vapours preferably contain at least 5% by weight of the said compound and fixation is preferably effected at 100‹ to 150‹C for 20 to 120 minutes. Disperse, azoic, cationic and vat dyes are employed, being applied as solutions, emulsions or pastes.

... 846,209. Semi-conductor junction devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 20, 1958 [Oct. 22, 1957], No. 33404/58. Class 37. In the sealing of semiconductor electrode system within metal envelopes by a cold welding technqiue, shielding is provided between the cold weld and the electrode system in order to protect the electrode system from gaseous or solid impurities developed during the cold welding process. As shown, a silicon diode 3 and 4 mounted on a copper base 2 is protected, during cold welding of tube 10 to lead wire 5, by screen 15 of mica threaded onto lead 5. Additional screening of the junction during cold welding of hood 7, base 1, and tin insert 12, is said to be normally unnecessary due to the screening provided by groove 6, but may be provided in the form of tubular screen 20. Specifications 561,111 and 775,191 are referred to.
