Title: Variable vol. constant height packaging of paper or plastic - has base, two broad sides and two narrow sides which are folded inwards along specified, but interchangeable lines
IPC: B65D5/42
Filed: 1989-09-08
Abstract: The invention relates to a paper or plastic packaging for loose contents of different weights. The packaging has a rectangular section and a base created by folded flaps which are bonded together. The package vol is altered by folding in the package at different points.  To achieve different volumes while maintaining a constant package height the package is designed as a folding box with a gabled end. The material is a stiff, but foldable card-board. Both gable-ended narrow sides have a folding line running downwards from the filling point. The line described also forms a starting point for two other fold lines which extend to the adjacent long edges of the narrow sides.  The two fold lines are inclined to the package base and are symmetrical about the middle axes of the narrow sides. Package volume is dependent on the position of the starting point of the two fold lines. USE/ADVANTAGE: Produces packages of constant height which can be simply adjusted for different volumes. Typically used for loose, pourable contents e.g. seasonings, spices.

Title: Solid phase peptide synthesis on floating carrier - by mixing solvents of differing densities so that the carrier is homogeneously dispersed without floating or precipitating
IPC: C07K1/04
Filed: 1990-03-01
Abstract: The synthesis of peptides by a solid phase method is improved by setting the density of the reaction mixt. by mixing with two or more solvents of different densities so that the polymeric carrier used distributes itself uniformly throughout the suspension and neither floats nor sinks. Pref. the coupling reaction is carried out first in a still system with a sedimenting carrier, and then, after a given time, a heavier solvent is added so that the carrier floats. Alternatively, coupling is carried out first with a floating carrier, and a lighter solvent is then added so that the carrier sinks. The density is pref. adjusted using halogenated or phosphorus or sulphur-contg solvents which are inert towards the coupling reaction. The density of the solvents is pref. adjusted using dissolved salts. The mixing is pref. carried out by achieving convection by warming. The carrier is uniformly distributed in the mixt. pref. by using sound or ultrasound. USE/ADVANTAGE - The carrier moves freely in the mixt. without either settling out as sediment or floating to the surface. The addn. of heavier or lighter solvents leads to intensive mixing of the suspension by convention and diffusion effects in an otherwise still system.

Filed: 1991-02-27
Abstract: In a pressure sensor (11), the force is introduced via a membrane (14) and a plunger (18) onto a piezoresistive measuring element (21). The measuring element (21) is part of a monocrystalline silicon chip (20). The piezoresistive measuring element (21) is connected to the monocrystalline silicon chip in a half-bridge circuit or a Wheatstone bridge circuit.

Title: Sepg. thermoplastic polymer from mixed materials - by suitably heating mixt. to soften the fraction required and then passing mix to rotary disintegrator where harder material is sepd.
Inventor: STRICKER URBAN DIPL ING
IPC: B03B9/06
Filed: 1992-06-24
Abstract: Mixed thermoplastics are sorted by heating the mixture to their specific softening pt. to form a rubbery material, or selectively softening it by a specific method such as h/f.. The thermoplastic polymer to be separated is heated to its softening temp. by convection or radiation heating; it is then fed to a disintegrator together with the other constituents of the mixture; by reference to the particle size and elastic properties concerned of the softened material it alone is actually disintegrated thereby, whilst the other materials pass through the feed and inlet areas without being reduced so that they are taken away separately. ADVANTAGE - The process combines selective softening with selective disintegration.
