The present invention relates to a novel method for the diagnosis of Alzheimer's disease using cerebrospinal fluid. More particularly, this method consists in contacting a sample of cerebrospinal fluid which contains a glutamine synthetase, having an apparent MT of about 42 000 daltons, with a labeled antibody specific for said glutamine synthetase under conditions that allow the formation of glut...

A method and apparatus for roll forming strip material in which the strip material (30) is first fed into a feed and cutting unit (14) in which a predetermined length of material is fed and cut off, and is then fed into a roll forming unit (16) which is driven at at least the same speed as the feed unit (14). The cut material is discharged onto a table (18). An alternative roll forming unit (17) c...

A method for manufacturing yarn guiding rings, includes a first step of blanking a plate (3) to form a plate body (1) constituted by a supporting element (7) and by a fork element, and a second step of bending the fork in order to obtain a circular ring. The fork element has two arms (5). Each arm is constituted by two portions with different curvatures (R, S). The outer portions of the arms are f...

A plurality of residual yarn removing devices (1a,1b,1c,...) for roving bobbins, which correspond in number to the number of fiber types of residual yarn of the roving bobbins (5A,5B,5C,...) are disposed in a transfer line for transferring the spent roving bobbins from a fine spinning frame (3) to a roving frame (2). The residual yarn removing devices are disposed in series to correspond to the re...

A cutting head for fabrics for the clothing industry, includes a body (4) which can move in a direction which is substantially parallel to the plane of arrangement of the products to be cut and supports a cutting blade (8) which oscillates transversely with respect to the plane; the head has electromagnetic means (A, B) which act directly on the blade to cause its controlled oscillation.

Centrifuge for the separation of a suspension into a solids phase and at least one liquid phase, especially decantering centrifuge with separator following in alignment, full-jacket screw centrifuge or the like with screw (2) rotating at differential speed of rotation from its jacket (1), the helices (4) of which fit close against the course of the inner surface of the jacket, which narrows conica...

The device comprises a housing (1) with an inlet chute at the top and a roller (2) having several teeth round the perimeter. Fixed teeth (3) designed as steel plates extending in the radial planes of the roller are provided on the device frame in the rising area of the roller and mesh with the revolving teeth. The fixed teeth are tapered at least on their narrow side facing the sleeve face of the ...

The method involves wetting a thread with water or other suitable preparation during pressing, before reaching the thread-collector (16). The thread-end is pressed into the thread-collector by an adjustable, elastically flexible force.A thread spooler has a changer (2) and at least one driven spool-spindle (5,6) with a chuck for clamping an empty sleeve (7) and to form a spool (8) on the empty sle...

The winding pattern (1) of continuous synthetic filament yarns (6) on a ring tube (2) consists of cylindrical layers which reduce in length as the dia. increases so that conical shoulders (11,12) are formed at the ends. At least the upper shoulder (11) is covered with several protective layers of yarn (6) formed at the end of the bobbin build cycle.

Prodn. of objects made of hard metal comprises forming a preform (green body) from a metal powder contg. a binder, and sintering. On preforming, a crystal and/or a ceramic is formed in the metal powder, and then the preform is sintered from the metal powder and crystal and/or ceramic.

A method for the preparation of polymeric foams which comprises reacting an organic polyisocyanate with a cyclic carbonate having at least one isocyanate-reactive substitutent attached to the carbonate ring.

A method for the preparation of cellular polymeric products which comprises reacting an organic polyisocyanate with an isocyanate-reactive composition, characterised in that the isocyanate-reactive composition comprises a blowing promoter which is a cyclic urea compound having at least one isocyanate-reactive substituent.

A method for obtaining quantitative compositional information from a multilayer web containing a highly light-scattering component. The compositional information is obtained by measuring and analyzing the transmitted or diffusely reflected infrared spectrum. The method allows for separately determining the moisture content of hydrophobic (non-hydrogen bonding) layers and hydrophilic (hydrogen bond...

The underframe (1) of the couch has legs (2,3) widening in a V towards the underside, and accommodates a seat and hinging backrests and legrests. Two armrests hinge on the backrest and lock into engagement with the underframe to position the backrest on it. On the underside of the legrest (9) and on the underframe are locking devices (19-21) for separate positioning of the legrest. The latter can ...
