Title: Slide fastener
IPC: A44B19/34
Filed: 1976-09-10
Abstract: A slide fastener comprises a pair of tape-like units each secured to one edge of an article whose edges are to be connected by movement of a slider along the units. Each tape-like unit comprises a row of interconnected coupling elements formed by a synthetic-resin monofilament, each coupling element having an eye or loop-shaped portion deformed to constitute the coupling head which can be received between coupling heads of the other row. From the eye-forming monofilament segments, shanks extend across the tape-like unit and are received in pockets of a multiplicity of longitudinal threads (e.g. as the weft of a weave in which the longitudinal threads form the warp, or in courses of the warp knit in which the longitudinal threads are loop chains). The slider has a pair of channels which merge into a common channel, the transition zone between the pair of channels and the common channel being superimposed to press the coupling heads of one row between the coupling heads of the other generally perpendicularly to the slide-fastener plane.

Title: Extn. of potassium bi:tartrate from hot grape must etc. - in crystalliser which cools by adiabatic expansion of soln. under vacuum
IPC: C12F3/06
Filed: 1981-09-18
Abstract: A process and an installation for the extn. of potassium bitartrate from hot grape must, pressed marc extract, secondary wines etc. The process is of the type in which the soln. is cooled to crystalise the bitartrate. A crystalliser vessel is used in which a reduced pressure is maintained above the level of liq. in the vessel. Hot soln. injected into the vessel is subjected to adiabatic expansion leading to partial evapn. of solvents, cooling of the remaining soln. and crystallisation of bitartrate. The crystals settle in the bottom of the vessel from which they are extracted for washing and drying. Evaporated solvents from the head of the vessel are pref. condensed in an indirect heat exchanger if they contain alcohol and in a spray condenser if they do not. Incoming hot soln. is pref. mixed with cooled liquor drawn from the central zone of the vessel. The mixt. is recycled into the vessel at a level just below the surface of liq. in the vessel. Previous crystallisers for this type of work have suffered loss of thermal efficiency as encrustation of crystals have built up on heat transfer surfaces. This has previously been overcome by scrapers and stirring blades but this troublesome soln. has now been superseded.
