A method and a device for separating a component, such as fibrin I from blood, by centrifugation. The method involves feeding of blood admixed an anticlotter to a first annular chamber in a device, where the annular chamber is defined by a cylindrical outer wall and a cylindrical inner wall, both walls extending coaxially about a common axis, as well as by a top wall and a bottom wall, where the t...

A reagent delivery system comprises an axial hub passing through the center of two equal-diameter, spaced apart discs, wherein the hub and discs are positioned in a sleeve such that an annular reagent chamber is provided. When the sleeve is moved in either an up or down axial direction the so-formed chamber is opened and the reagent is released. Such a regent delivery system is particularly useful...

A method and a device for separating a component, such as fibrin monomer from blood, by centrifugation, involve feeding of blood admixed an anticoagulant to a first annular chamber in a device, where the annular chamber is defined by a cylindrical outer wall and a cylindrical inner wall, both walls extending coaxially about a common axis, as well as by a top wall and a bottom wall. The top wall or...

A machine producing cross-wound bobbins or cheeses has a yarn guide rod including axially coupled-together partial rods. Each partial rod includes a tubular abrasion-proof jacket, and a compact bar body being formed essentially of fibers embedded in a plastic matrix and being disposed in and joined to the tubular jacket in a shift-proof manner.

The wire 4, intended to form a carcass reinforcement, is wound in contiguous hoops on a rigid core 1, by means of an eyelet 33 fixed to a chain 30 mounted on pulleys 31, so as to flank the core 1. The eyelet 33 carries out a to-and-fro movement around the core 1 so as to position, progressively and in a contiguous manner, a hoop at each forward stroke and a hoop at each return stroke.

The invention relates to an aseptic bottle or container (1) for preserving a sterile liquid product (2). This container is characterised in that the outlet tube of the container (3) is designed in such a way as to define at least one narrow passage (6), sufficiently long and having a restricted flow cross-section, the length and cross-section of this narrow passage (6) being adjusted according to ...

A device for steering and maintaining the course of a vehicle contains, in addition to a device for detecting the position of the vehicle, and a steering control device which acts on a steering angle adjustment device, a preselectable limitation of the steering angle setting requested by the control. A steering angle setting requested by the control is combined with the steering angle setting requ...

The appts. includes a special spectrophotometric container which is partially filled with the liquid to be analysed. The liquid is modified by the addition of a reactant. Within the transparent container there is an equilibrium between the liquid and vapour phases. The vapour phase is traversed by a beam of light which is subject to spectral analysis at the output. The signal is processed by Fouri...

The wheelchair has a chassis (1) carrying a seat (2) and fitted with driving and steering wheels (3,4) and with two systems of detectors that can be automatically switched. One set of detectors are optical (8) and follow a white line painted on the ground, the other set is inductive (9) and follow a cable set in the ground and carrying an alternating current. The detectors deliver signals to a mi...

Expandable styrene polymers formed from 50 to 83% by weight of polystyrene and from 17 to 50% by weight of styrene-soluble styreneacrylonitrile copolymer having a total acrylonitrile content of not less than 5% by weight, containing from 3 to 10% by weight of a C3-C6-hydrocarbon with or without customary additives, are notable for high oil resistance and can be prepared by suspension polymerizatio...

Expandable polymers in particle form for the preparation of foams having high heat distortion resistance contain from 20 to 94.9% by weight of a styrene polymer, from 0.1 to 75% by weight of a polyphenylene ether and from 5 to 20% by weight of a blowing agent mixture of aliphatic or cycloaliphatic hydrocarbons on the one hand and aromatic hydrocarbons, alcohols, ketones, ethers, esters and/or chlo...

A multi-filament yarn is subjected to soft twist of 4 to 9 twistings in every 10cm in a single direction thereby forming a warp yarn 2. Weft yarns 3 are passed, at a density of 1 to 3 yarns in every 5cm, crosswise over and under a plurality of the warp yarns 2 parallel-arranged in a set width, thereby forming a cord fabric 1. The cord fabric 1 is subjected to adhesion treatment with an adhesive so...

With a differential gearing having a spur gear construction, the compensating gears (31a, 31b) are installed in meshing pairs and are tightly enclosed by a housing (14) so that with meshing spur gears (22, 23) they can act as toothed pumps with pressure zones, with a locking moment being produced between the two driven shafts (2,3). A substantial increase in the locking moment is achieved in that ...

To prevent a motor vehicles engine being forced over its speed limit as a result of erroneous selection of a too low a gear during gear changing while still providing engine braking, a clutch between engine and gearbox is caused to slip. The clutch, mounted between the engine and a gearbox, is automatically engaged/disengaged by a setting member controlled by a micro-controller which immediately d...

The method for tracking and management of parts from fabrication to use identifies each part during fabrication with identifiers that are written on an area of the part that is readily readable by an automatic reader. The data is read and stored in a local or central database. To deliver parts to where they will be used they are packed in boxes. Each box is similarly marked with information that c...

The differential (1) comprises an input movement crown wheel (3) solidly attached to the differential housing (2), enclosing on the one hand a satellite axle (7). The satellite acts via intermediary satellites first and second planetary systems (9,11). These transmit half of the motor's torque to each of the two driving wheels of the vehicle when they have sufficient adhesion on the road. The diff...
