Patent NO-172923-B (NO)
Inventor: LUNDBAECK STIG
IPC: A61M60/876
Filed: 1985-03-29
Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Abstract: 1,138,722. Laminated fabric. APPLETON WIRE WORKS CORP. 19 Jan., 1966 [8 Feb., 1965], No. 2467/66. Heading B5N. [Also in Division D1] A fabric formed by sewing filaments together comprises a plurality of substantially straight and parallel segments of rack filament 12 disposed in a plane, one or more sewn filaments 16, 18 stitched in parallel rows transversely across the rack filament segments, a filler 14 of non-woven fibres sewn to the rack filaments by the sewn filament or filaments, and means bonding the or each sewn filament to the filler filaments and the segments of rack filaments. The fibres used in the fabric may be one or combinations of man-made fibres, e.g. viscose, nylon, polyester, e.g. Dacron (R.T.M.), acrylic, fluorocarbon and glass materials, or natural fibres e.g. cotton, and may be or treated to be non-absorbent of water. The fabric may include metal or mineral fibres. The fabric fibres may be bonded by adhesive resins. In one method of forming the fabric, Fig. 4, a web of filler 14 is fed into contact with rack filaments 12 spaced in parallel relationship on a rack 24, and the assembly passes beneath a sewing machine head 32 where the filler is sewn to the filaments 12 by sewn filaments 16, 18. To prevent weakening of the filaments 12 by piercing with the sewing machine needle the stitches are made between them or a dull needle is used. In an alternative method of making the fabric the rack filaments are looped round pegs at each end of a rack so that a single sheet is produced. In a method of making the fabric in the form of an endless belt, e.g. for use as a Fourdrinier wire in a paper-making machine, the filaments 12 are individually spliced to form closed loops, or a single rack filament is wound helically about a group of supporting rolls. The sewn filaments 16, 18 may be of different diameters or different materials to impart different properties to the faces of the fabric, e.g. one surface may be made abrasion resistant and the other smooth. The filaments may be sewn using a lock stitch, a two filament chain stitch, or a single filament chain stitch. The rack filaments, which may be mono-filaments, may be concentrated at various points, e.g. at the centre or edges, to provide greater strength there, or filaments of different diameters can be used. Filler may be applied to both sides of the rack filaments or vice versa. The filler filaments are preferably longer than the space between adjacent sewn filaments, and the needle holes formed in the filler may be reduced by shrinking the filler about the holes, e.g. by heat, e.g. during curing of the bonding resin. The fabric may be used as a filter, in which case it is permeable, as upholstery or drapery material, as a wall covering, or as conveyer belting e.g. as an absorbent felt in a papermaking machine.

Inventor: DEWAR R
IPC: C07C67/00
Filed: 1965-04-13
Abstract: An a ,b -olefinically unsaturated nitrile or ester is reductively dimerized by bringing an alkali metal or alkaline earth metal amalgam into interaction with a reaction medium containing the nitrile or ester, a salt that provides alkylated cations in the reaction medium, and an agent such as water or an alcohol that can donate active hydrogen and co-operates with the amalgam to provide an amalgam reduction system.  Suitable starting materials are acrylonitrile and alkyl - substituted acrylonitriles ("alkyl" having up to 4 carbon atoms and including alkenyl and alkynyl with the unsaturation not adjacent to the acrylonitrile double bond), and mono- and di-carboxylate esters.  The salts used may be alkylated ammonium, phosphonium or sulphonium salts. Inorganic salts such as CrCl3 or Na2CrO4 may be added as promoters.  Polar solvents, such as dioxane, acetone, dimethylformamide or ethylene glycol, and polymerization inhibitors, such as N1N-dimethyl p-nitrosoaniline, may be present. When using alkali metal amalgams the constant addition of an acid or CO2 is required. Ambient temperature is preferred.  Examples prepare adiponitrile, 3,4-dimethyl adiponitrile and diethyl adipate.

Title: Radiant heating unit
Inventor: KICHERER ROBERT
IPC: H05B3/74
Filed: 1986-05-15
Abstract: In a radiant heating unit, an insulating support for carrying a radiant heating resistor is molded or pressed using a granulation of expanded clay materials, particularly expanded mica or vermiculite. The granulation is compressed and bound in a blank by a mineral binder, particularly water glass, and the heating resistor is positively secured in the moulded granulation by embedding parts of the resistance wire forming the resistor, in such a way that the resistor is in part free of the insulating support on the front. The heating resistor can be embedded during production of the insulating support or can subsequently be pressed into the support. The insulating support of the heating unit is low in weight and easy to manufacture, has optimum electrical and thermal insulating properties and has very good strength, whereby the heating unit has a long service life.
