Abstract: INVENTOR:  HANS SIGG         INVENTION:  AUTOMATICALLY ENGAGEABLE JAW CLUTCH     ABSTACT OF THE DISCLOSURE     An automatically engageable jaw clutch having a toothed drive hub, a toothed power take-off hub, and a clutch star axially displaceable with respect to the power take-off hub.  The clutch star is continuously connected with the drive hub for conjoint rotation by means of first teeth means formed thereat and has second teeth means which can be brought into engagement with the teeth of the power take-off shaft by axial shifting of the clutch star.  A screw socket or sleeve which is connected by means of a pair of coarse-pitch threading with the power take-off hub, is only conjointly axially displaceable together with the clutch star and rotatable relative thereto.  The screw socket is entrainable by the clutch star by means of a pawl block-ing mechanism composed of a pawl and ratchet teeth, when the drive hub overrides the power take-off hub.  A switching device serves for selectively rendering ineffectual the pawls and contains a sleeve which is axially adjustable in relation to the clutch star and equipped with a ramp surface which, in a predetermined axial position of the sleeve in relation to the clutch star, hinders the pawls from engaging with the ratchet teeth.

Abstract: Title:          Method and apparatus for electro-optically convoluting a one-dimensional signal.     Abstract of the disclosure:       A method for electro-optically convoluting a signal representing a profile formed during X-ray tomography and a filter function. The signal is electro-optically, one-dimensionally reproduced as a line along which the brightness varies and the filter function is laid down in one or more masks. A photodetector is mounted behind each mask for detecting the light transmitted by the masks when an image of the signal is moved past the masks. The one-dimensional image of the signal is expanded in a direction transverse to the line by means of an optical system and the expanded image is moved past the masks in the direction of the line. The masks contain only regions that are either fully transmissive or fully non-transmissive.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and composition for the in-flight encapsula-tion or particles such as insecticides, herbicides, mollusci-cides, acaricides, fungicides, nutrients, pheromenes, odorants, fragrances, attractants, repellants, trace elements, and the like.  The composition comprises, by weight, from 1 to 40 per-cent of said particles, from 0.3 to 25 percent of a film-forming polymer and from 35 to 99 percent of a solvent which renders said polymers soluble.  Often, other compounds may be added to impart desirable properties such as a second film-forming poly-mer, crosslinking agents, film modifying agents, and adhesives to improve adhesion to a target.  The particle may be in a true solution  suspended  or emulsified through the action of sur-factants and/or emulsifying agents.  The film-forming polymer is selected from the class consisting of polyvinyl ethers, polyvinyl acetate, and interpolymers of alpha-beta olefinically unsaturated carboxylic acids and N-methylol acrylic amides, a-set forth in U. S. Patent No. 3,007,887.  Upon ejection from a spray apparatus and during flight through the intervening atmosphere, the solution rapidly loses the solvent component via evaporation, coacervation occurs, and a polymeric membrane forms about the particle.  Control of the encapsulated particle size can be achieved through selection of the spray system and of the non-volatiles in the spray at the moment of droplet formation.

Abstract: ABSTRACT         A connector spike for use with a dual-purpose one-piece plastic closure for surgical irrigation fluid containers is disclosed.  The closure has a port sleeve which has a primary sealing zone at a level slightly below the closure's top wall, and a secondary sealing zone between the primary zone and the dome-shaped bottom wall of the port sleeve.  The connector has a handle portion and a spike portion with the tubular wall of the spike portion terminating in a beveled  cutting edge which is adapted to pierce the bottom wall of the closure.  The cutting edge slopes upwardly from a tip portion towards a heel portion, the latter being provided with an upwardly extending smoothly contoured recess which interrupts the cutting edge.          The wall of the spike portion has upper and lower portions of different diameter for engaging the primary and secondary sealing zones of the closure respectively.  The recess contributes in preventing air entering an inverted solution bottle from becoming entrained in liquid being drained from that bottle.

The test comprises in combination, (a) an insoluble polymeric solid having antibody reactive with antigens associated with hepatitis bonded thereto for immobilizing hepatitis antigens from the sample, the surfaces on the solid being distorted to comprise a field of high and low points to provide a solid which, when placed in a flat-bottomed vial will be substantially in contact with any solution in the vial while minimizing surface-to-surface contact; (b) an alkaline phosphatase - antibody conjugate reagent for labelling hepatitis antigen immobilized on the solid; (c) an enzyme substrate capable of being chemically changed under the catalytic influence of the alkaline phosphatase; and (d) a flat-bottomed vial sized to reaceive the solid.  The test is used in a sensitive direct immuno-assay system for detecting antigens associated with hepatitis involving the use of an enzyme-tugged antibody which reacts with an antigen to detect the presence of hepatitis.  The test has an extended shelf life and the use thereof greatly simplifies the procedure of the assay.
