Abstract: A spinal implant fixation assembly includes a bone fixation member, such as a screw or hook for fixation to a bone. A rod receiving seat is operatively connected to the bone fixation element for seating a portion of a rod therein. A locking mechanism, in the form of a nut and locking ring engage the rod receiving seat for forcing an inner wall of the rod receiving seat to contour around and engage the rod seated therein and for locking and fixing the rod relative to the inner housing. In one embodiment, the locking ring secures a head portion of the bone fixation element within the assembly. A method is also provided for locking the rod to a bone by fixing a rod seating member to a bone and seating a portion of a rod within a substantially U-shaped seat of the seating member. The rod is then locked within the U-shaped seating member while engaging and contouring at least a portion of the U-shaped seat about the rod.
Abstract: A propulsion system for a conveyor for the transportation in single file of uniform items such as fillable containers which have a neck portion.

The propulsion system comprises means for generating momentum and suitable transfer means for transferring the momentum thus generated to the containers. The transfer means comprises means for applying mechanical force to the said containers.
Abstract: A biological sensor 10 having a beam/light shaper 30 which is adapted to inject light into the sensor at substantially the critical angle with respect to the side surface of the sensor. The sensor 10, of the preferred embodiment of the invention, further may undergo a surface treatment which reduces/eliminates non-specific binding to the sensor surface and a treatment process to reduce light energy losses occurring by mounting and/or inserting the fiber portion of the sensor into the medium of interest. Both the light injection and surface treatment methodologies have utility apart from the biological immunoassay sensor embodiment described and claimed in this Application and may be independently applied to a biological sensor.
Abstract: A method of forming phosphine-amine conjugates includes reacting a hydroxymethyl phosphine group of an amine-free first molecule with at least one free amine group of a second molecule to covalently bond the first molecule with the second molecule through an aminomethyl phosphorus linkage and the conjugates formed thereby.

Abstract: A container bag (10) having a base (14), side walls (12) and lifting loops (16) is characterized in that the central portions (15) of the side walls of the bag or of a liner within the bag are stiffened relative to the corner portions whereby to effect a squarer shape to the bag. The stiffening may be achieved by fabric from which the bag (or liner) is to be made being selectively stiffened in those areas destined to form the central wall portions by using different weave densities, more or additional threads of either the same or a different kind, additional layers of material being attached e.g., by adhesion in the relevant areas, or a stiffening coating composition e.g., of a polymer applied.
Abstract: The present invention relates to novel alternative forms of human acetylcholinesterase (AChE) and nucleotide sequences encoding the same. The genes encoding the novel forms of human AChE have been identified in various malignant tumor cells. In a further aspect, the invention relates to a transgenic animal assay system for evaluating efficacy of drugs against cholinergic proteins, prior to or in the course of therapeutic treatment. Transgenic animals, preferably developing tadpole of Xenopus or mice which express human AChE, are used. The transgenic animal assay system is also useful for evaluating the toxicity of substances which potentially block human AChE (e.g. organophosphorous compounds).
