2068990 9108253 PCTABS00005 Flexible composition on the basis of a soft polyurethane binder with a low modulus and at least one filler, which composition after curing has a possible elongation at ambient temperature of at least 50 % characterised in that it contains 0.1 to 10 wt% expanded polymerparts with a size of 2 to 300 micrometers.

Prefoamed synthetic resin particles are produced by dispersing foamable resin particles in a dispersing medium within a closed vessel, said foamable resin particles containing a water-soluble inorganic substance and a blowing agent therein, and then releasing the foamable resin particles and the medium into an atmosphere of a pressure lower than that inside the vessel, whereby the thus-released fo...

2069438 9108373 PCTABS00005 A pipe system comprises a plurality of pipe members (2), mechanical connections at the end regions of the pipe members whereby the pipe members can be connected together into end-to-end relationship to provide at least one fluid flow path along them, and electrical conductors (10; 110) carried by the pipe members, the electrical conductors having contract areas (19) exp...

This invention relates to a method and an apparatus in the recycling of plastics, by which it becomes possible to handle and to take care of the materials in a plant without preceding sorting into different kinds of plastic. After a possible coarse sorting for removing foreign materials the waste plastic is supplied to an apparatus (5) for disintegration and washing with water containing a grease ...

A low-overhead method of protecting multi-pulse speech coders from the effects of severe random or fading pattern bit errors combines a standard error correcting code (convolutional rate 1/2 coding and Viterbi trellis decoding) for protection in random errors with cyclic redundancy code (CRC) error detection for fading errors. Compensation for detected fading errors takes place within the speech c...

A method for making a casting nozzle, includes mixing a main casting nozzle material 70-95% by weight and electrofused aggregates 5-30% by weight, the electrofused aggregates consisting essentially of ZrO2 30-60% by weight, Al2O3 20-50% by weight, SiO2 10-20% by weight and SiC 5-40% by weight together with a binder, thereby to make a mixture, forming the mixture in the shape of a casting nozzle th...

A female mold portion (1) and a male mold portion (2) co-operate to provide a space corresponding to the part to be molded, a fabric blank is cut out of the same size as the bottom of the female mold portion (2), without projecting therefrom, and is placed on the bottom of the female mold portion, and the mold is then closed, to compress the fabric. The closed mold may be evacuated, and resin may ...

The belt, particularly for garments, with a two-part closure (2) for the belt ends (1,1'), is coupled together by interlinking the coupling parts (5,6). The belt end (1) is passed in curves (8) through the interlinked coupling and then clamped and held. If one of the coupling parts (5,6) is moved manually, the closure opens and the clamped belt end (1) is released. ADVANTAGE - The belt is opened a...

A mechanical pipe expander having a pyramidal, polyhedronal cross-section, segments resting against the pyramidal surfaces which are displaceable in axial direction relative to the polyhedron, and grooves formed in the longitudinal centers of the edges of the polyhedron so that the side surfaces of the grooves represent guides for the correspondingly shaped segments. The segments are formed as dov...

A pad for use on a floor-polishing machine comprises a circular, non-abrasive body defining a number of openings, each of which contains a relatively abrasive insert (12). The inserts can readily be replaced.

The invention relates to a distributed amplifier for wide band hyperfrequency signals of the type comprising: a plurality of basic amplifying cells (C1 to Cn) mounted in series, with at least one common drain line (Ld) and at least one common grid line (Lg), each cell comprising at least one field effect transistor (T1) which is common-source mounted and filtering elements, first biasing means for...

The present invention relates to the use of a gelling agent between the plastic seal and the outer cover of an electrochemical cell.

A film sheet load magazine is adapted to hold a stack of superimposed films with at least central portions of the films in a curved configuration and leading ends of the films adjacent a film separator mechanism. The curvature of the films is such that they retain themselves in desired positions in the magazine independent of the orientation of the films with respect to gravity. When a top cover o...

CONVECTIVE ACCELERATION FLOWMETER A mass flowmeter comprises a conduit (1) with two extremities (5 and 6) secured to a support (4), which conduit includes a first and second end sections (7 and 8) extending from the respective secured extremities thereof in a cantilever-like arrangement and a curved midsection (9) connecting the first and second end sections (7 and 8) to one another, an electromag...

In a fluidized-bed reactor having a specific equivalent diameter and made of a material with a particular iron content, hydrogen chloride and oxygen are reacted in particular gas volumes and at specific molar ratio, superficial velocity, temperature and pressure in the presence of a catalyst composed principally of a chromium oxide and having a specific particle size distribution. The catalyst is ...

In a slurry dewatering process, slurry is pumped into a porous tube at a sufficiently low velocity for laminar flow conditions to exist. The pressure is sufficiently high for liquid in the slurry to permeate outwardly through the tube wall and for solids in the slurry to be deposited in the form of an annular cake on the tube wall. The deposition of solids is controlled so that the cake thickness ...

An RF converter circuit of a simplified structure includes a tuner circuit, an intermediate frequency amplifier circuit and a frequency conversion circuit connected in this order. An automatic gain control circuit is provided for reforming an intermediate frequency signal from the intermediate frequency amplifier circuit and transmitting the reformed signal to the tuner circuit such that an interm...

An apparatus for selecting one of a number of television channels is operable to be set in a mode whereby an array of miniature pictures corresponding to the respective channels is displayed, with each channel being sequentially selected for a predetermined interval during which image data for the selected channel are repetitively written into one of a set of regions (42 to 50) of a one-field memo...
