Patent DE-2529658-A1 (DE)
Inventor: OPITZ KONRAD DIPL CHEM
IPC: D06P1/38
Filed: 1975-07-03
Abstract: Stable, concentrated, aqueous or water-containing solutions of reactive dyestuffs of the formula (I> (HO3S)m-F-Zn and their salts, where the meanings of the symbols F, Z, n and m are defined in Patent Claim 1, have a pH between 3 and 7 and are characterised by a content of 10 to 50 % by weight of one or more dyestuffs of the formula (I) in the form of their salts, of 10 to 30 % by weight of one or more solubility-enhancing N-alkylated amides of lower carboxylic acids, of phosphoric acid, of carbonic acid, of sulphoxides and of cyclic sulphones, and by a content of buffer substances. By mixing with water and other auxiliaries, dye baths, dye liquors and printing pastes can be prepared from them very rapidly and avoiding the otherwise customary dusting of powdered dyestuffs. They are stable on very long storage, even at relatively high temperature, and retain their dissolving property and their tinctorial strength, since no loss of the reactivity of the dyestuffs occurs.

Title: Wind surfer mast foot self-acting coupling - has elastic mast base plug closely fitting into socket in hull with locking by axial compression
Inventor: BAUR VINZENS MAXIMILIAN
IPC: B63B35/79
Filed: 1976-09-30
Abstract: The windsurfer mast foot self-acting coupling provides a releasable connection between mast and hull. It leaves mast tilting and mast rotation completely unrestricted. At the base of the mast (5) there are two sleeves (1, 2) connected by an omnidirectionally flexible link (8), pref. a rubber cylinder. The lower sleeve (2) is stepped (3) to fit into a socket (6) in the hull. There is a second elastic cylinder (9) projecting from it which fits the socket closely. A line (14) runs through axial holes in the cylinders; nuts (12, 12a) - with washers (13) - on studs (10, 11) connected to its ends allow it to be tautened, holding the assembly together. Any tilting of the mast relative to hull increases line tension, forcing the lower cylinder to expand sideways, locking the coupling.
