Title: Three-layer solid phase binding assay techniques
Inventor: HUGGINS KEITH G
IPC: G01N33/68
Filed: 1978-12-14
Granted: 1981-12-15
Abstract: SPECIFIC BINDING ASSAY TECHNIQUES ABSTRACT The standardization of a labelled-constituent, such as anti-IgE, for use in a specific binding assay method is disclosed. The method involves standardizing a labelled ligand (eg., radiolabelled IgE) against a ligand reference substance (eg., WHO standard IgE) to determine the weight of IgE protein represented by the labelled ligand, expressed in terms of the reference substance (eg., WHO units). Anti-light chain antibodies are attached to a solid phase and contacted with varying concentrations of the labelled ligand to bind the ligand to the anti-light chain anti-bodies. The ligand is then contacted with the labelled constituent and the amount of labelled constituent, in relation to the amount of ligand protein present, expressed in terms of the reference substancej is determined. The labelled constituent is thus standardized, since the actual weight of a ligand can be determined from the amount of labelled constituent bound thereto. Also disclosed is an improved specific binding assay test method for determining the potency of an allergen extract. The test method generally involves inhibition by the soluble extract, of the binding of a ligand (provided by serum from an allergic individual) to solid-phase allergen as assessed by the standardized-labelled constltutent (anti-IgE). The improvement involves using a parallel model system of a second complex which consists of anti-light chain antibodies, labelled ligand and the standardized labelled constituent. Because the actual weight of a ligand bound to the labelled constituent is known, from the standardization procedure described above, the amount of standardized labelled constituent bound to the ligand in the first complex can be determined. The weight of ligand inhibited by addition of soluble allergen is then used as a measure of the potency of the allergen extract.

Abstract: ABSTRACT OF THE DISCLOSURE         A sedimentation apparatus, clarifier or thickener uses an annular feedwell which delivers influent feed to a position near the bottom of a settling tank, at which position the influent feed is deflected radially outward and inward by a substantially horizontal concentric annular baffle.  It is possible to maintain a substantially uniform dynamic sludge bed in settling tanks of large diameter and to achieve a high throughput of solids per unit area of settling tank by the use of this invention.  By using an annular feedwell with associated planar horizontal baffle plate it is possible to effect a more even distribution of feed and solids to be settled throughout the tank.

Abstract: ABSTRACT OF THE INVENTION        The object of the invention is a rope-clamping device, the essential components of which are mobile clamping elements which enclose between them a clamping gap, and the surface parts of which, co-operating with the rope, consist of rollers having teeth and a rotationally symmetrical envelope.  The distance between the rollers is adjustable under the action of a force and the said rollers rotate freely upon their axis.  The rope is clamped in the clamping gap when the rollers are rotated and the distance between them is increased.  They are thus held positively and by friction, but are easily released in the opposite direction.  In the direction of tension of the rope, locking occurs.  In the opposite direction the rope may easily be retensioned.  An additional advantage is that the clamp does not damage the rope.  The axis of the rollers are prefer-ably arranged at an acute angle to each other, the rollers being longitudinally displaceable upon the said axis.   Several pairs of rollers may be provided.  A possible accessory may be an adjustable reference surface supporting the rope.  The object of the invention may be used for sail-boats, automotive vehicles, hoists, ski-bindings and back-packs.

Abstract: ABSTRACT OF THE DISCLOSURE     In an ice disaggregation system employing teeth affixed to a bracket which is spirally disposed around the outer periphery of a cylindrical rotating drum and held in spaced relationship therefrom, the cutting cap-acity is improved by tilting the plane of each tooth with respect to the drum's axis of rotation such that each incremental section of ice which a tooth engages is subjected to a bending force about a pivot near an area from which ice has been removed is therefore rela-tively weak.  As a result, the ice readily fractures in relatively large chunks.

Abstract: Abstract of the Disclosure The manufacture of large scale wind turbine blades is accomplished by winding composite fiber materials onto a mandrel to form the desired airfoil shape.  The winding process requires that the fibers always maintain contact with the mandrel surface.  If the surface is concave the fibers will form a bridge over the concave surface por-tion which produces a void.  This invention avoids bridg-ing by analysis of the mandrel surface design including the steps of defining a plurality of coordinate points on the sur-face prior to winding thereof, and determining if a concavity will occur in the fiber winding plane passing through each coordinate point.  If a concavity is located, the mandrel design coordinate point at the concavity is modified to elim-inate the concavity and provide a continuous flat or convex surface in the fiber winding plane.  The process can be auto-mated by clerical or computing methods, and is repeated for each coordinate point until bridging is substantially eliminated.
