Abstract: Docket No. 11625 TEST DEVICE AND METHOD FOR DETERMINING A      COMPONENT IN A SAMPLE                 ABSTRACT OF THE DISCLOSURE     A test device and method for determining the presence of a component in a sample are disclosed, as well as a method for making the device.  The device utilizes a re-actant system which produces a detectable response upon contact with the sample component, the reactant system being incorporated with a carrier matrix.  The carrier matrix comprises separate filaments formed into a cloth. At least one ingredient of the reactant system is incorporated with some of the filaments prior to their being formed into the cloth.  The method for making the device comprises inter-weaving the filaments bearing at least one reactant in-gredient into a warp of other filaments, knitting the filaments into a cloth, forming a mat cloth of randomly oriented filaments or affixing the filaments to a matrix support member in a substantially parallel orientation.

Abstract: A B S T R A C T     In a self cleaning enclosure for production of livestock including hogs an enclosed slightly conical cir-cular surface is disclosed which includes a scraper extend-ing radially outward over the enclosed surface and rotational over the surface to effect cleaning and sanitization of the surface.  The scraper includes a conveyor system which may be out of direct contact with the surface and which carries the waste material outward along the scraper to a trench encircl-ing the enclosed surface and serving as a depository for the waste.  A trench scraper is carried with the surface scraper, and extends into the trench for moving the waste to a localized outlet for removal of the waste from the trench.  A motor causes rotation of the scraper around the surface and also causes operation of the conveyor system.

Abstract: La sonde ionique de l'invention comporte une électrode centrale de source, une électrode "transparente" et une électrode collectrice.  Pour éviter tout courant de surface à l'intérieur ou à l'extérieur du corps de sonde, on réalise celui-ci en plusieurs tronçons symétriques par rapport au plan de symétrie de l'électrode de source, le premier tronçon portant cette électrode de source, et le second tronçon portant les deux autres électrodes, séparées entre elles par un anneau isolant.  Le second tron çon est séparé du premier par un anneau de garde.  Un troisième tronçon sert au raccordement des conduites dans lesquelles passe le fluide à mesurer.  Cette sonde ionique est particulièrement utile pour la mesure d'un débit d'air ou d'essence.  Cette sonde ionique peut être associée à un circuit électrique de mesure connu, et peut alors permettre de mesurer aussi bien des vitesses d'écoulement que des débits massiques de fluide en écoulement, et ce, dans de nombreux domaines de l'instrumentation de mesure. Dans le domaine automobile, la sonde de l'invention peut être utilisée pour la mesure du débit d'air en combinaison avec un système d'injection d'essence d'un moteur à combustion interne.  La sonde peut aussi convenir à la mesure de liquides électriquement isolants, en particulier d'hydrocarbures liquides.

Abstract: CONVEYOR FOLDING AND MOLDBOARD OPERATION        FOR EXCAVATING AND LOADING SYSTEMS          Abstract of the Disclosure The present invention relates to an excavating wheel.          The wheel is comprised of a pair of spaced apart side plates each extending radially outwardly with respect to a central axis of rotation.  A plurality of stationary walls each extend between the side walls and each have outwardly pro-jecting material cutters.  A plurality of movable walls each extend between the side walls and cooperate with one of the stationary walls to define a digging bucket.  The walls thereby define a plurality of digging buckets positioned immediately adjacent one another to define the entire peri-phery of the excavating wheel.  Each of the movable walls are supported for pivotal movement between a material receiving position and a material dumping position.  A unit is provided which is entirely enclosed and which is responsive to the rotation of the wheel for positively pivoting the movable wall of each digging bucket to the material receiving posi-tion during one portion of the rotation and for positively pivoting the movable wall of each digging bucket to the material dumping position during another portion of the rotation.  The unit is comprised of a plurality of push rods each connected at one end to the movable wall of one of the buckets, a collar connected to the ends of the push rods remote from the movable wall, and a unit for constraining the push rods to rotation with the buckets.  A support is provided for rotatably supporting the collar at a point offset from the axis of rotation of the buckets and thereby actuating the push rods to pivot the movable walls to the material dumping position when their respective buckets are positioned over the material receiving portion of a conveyor.

Abstract: ABSTRACT            Packing containers for liquid are often made from a tube of flexible packing material, which is  filled with the liquid and thereafter transversely sealed and cut into separate, completely filled packing containers. This method has however hitherto been impossible to use for production of packages for aerated beverages and the like, as such beverages tend to froth when they are filled into the tube. According to this invention the abovementioned disadvantage is avoided in that the liquid to be filled is kept under pressure during its transportation to the bottom end of the tube, where a closed and with liquid completely filled space is limited by the tube itself and by an element which supplies the liquid.

Abstract: CYTOLOGICAL ASSAY PROCEDURE            ABSTRACT OF THE DISCLOSURE         Disclosed is a method of bioassay based on the detec-tion of changes in the membrane potential of individual cells.  A cell suspension is incubated with a solution of a substance capable of affecting the physiology of at least a subpopulation of cells in the suspension.  During or after the incubation, a measurement representative of the membrane potential of indivi-dual cells is made.  Comparison of these measurements with reference measurements provides information concerning:  1) the viability of the cells or a subgroup thereof after exposure to toxic substances; 2) the presence and concentration of factors or ligands in the solution which bind specifically to cell membrane receptors; 3) the presence of cells in the suspension sensitive to factors known to be present in the solution; 4) the cumulative effect of plural factors in the solution on the cells or a sub-population thereof; and 5) comparisons among the effects on the cells of plural, chemically distinct factors.  The preferred method of measuring membrane potential involves incubating the cells with a membrane-permeant, fluorescent, ionic dye which becomes distributed on opposite sides of the cell membrane as a function of membrane potential, and then assaying intracellular dye concentration by photometric measurements in a flow cyto-meter.
