Abstract: ABSTRACT          An apparatus to simulate a woodgrain finish on composite wooden sheet material.  The apparatus comprises a plurality of burner heads coupled to a gas supply and each having a row of transversely disposed nozzles.  The burner heads are mounted on transversely disposed rods longitudinally reciprocated in their mountings.  Reciprocation of the rods is by a cam associated with each rod, the cams being of different profiles and/or timing relative to one another.          With ignition of the nozzles corresponding carbonisation scorch lines are formed on the surface of the sheet as the sheet is passed through the apparatus.  The reciprocal action of the burner support rods imparts a substantially wavy motion to the lines,  a  random wave pattern resulting from the varying profiles and timing of the cams.  The scorching results in minimal charring and the surface is finish sanded to remove raised smut.

Abstract: METHOD FOR MAKING PURE BETA SILICON CARBIDE               ABSTRACT OF THE DISCLOSURE          A method is taught for making beta silicon carbide in a microballoon  structure, that is a spherical type structure in which the beta silicon carbide forms only a thin wall of the balloon structure.  If desired, the micro-baloon structure, which is porous, may be crushed to form beta silicon carbide of a very finely divided size.  The method is accomplished by pyrolyzing microballoon structures formed of an organic material so that the material breaks down to leave carbon behind in the microballoon structure.          This carbon is reacted with silicon at an appropriate temperature to form the pure beta silicon carbide in the microballoon shape.

Abstract: ABSTRACT OF THE DISCLOSURE          A ball valve assembly that is uniquely suited for use in extremely high and low temperature applications where solid particles are frequently present within a flowing fluid.  The valve includes a one-piece ball and stem or shaft element and the bore of that ball together with separate, removable end members, inserted from opposite directions into a passage extending through the valve body, form the valve's fluid-flow path.  The valve body includes a second bore which can either extend through the entire valve body, perpendicularly with the other passageway, or can instead extend perpendicularly from that passageway to the exterior of the valve body in only one direction.  The ball stem is rotatably retained and sealed in this second bore and the bore is dimensioned so as to be at least as large as the diameter of the ball so that the ball can be removed therethrough.  In one embodi-ment the inner ends of the separate end members forming part of the fluid flow path are shaped to correspond to the exterior shape of the ball and contain a solid seat and a solid elastically compressible behind-the-seat seal. In another embodiment in-line removal of the ball and stem element is possible due to the use of separate cylindrical sealing elements positioned between the ball which also form part of the flow passage and seal the area between the ball and end members.  The mating surfaces of the end members and the cylindrical elements are curved in a cooperating fashion to allow the cylindrical elements to rotate around the end members into a recess located in the valve body so that the ball can easily be removed through the second bore.

Abstract: SKATE BLADE          Abstract of the Disclosure An ice skate runner for use in a skate holder has an elongated metal body with a solid central portion and a pair of elongated cut-outs, one on either side of the central portion extending towards the end of the runner.  The portion of the cut-out adjacent the central portion is wide and the cut-out tapers downwardly in width towards the end of the runner.  The plastic holder for the runner is molded around the latter so that the plastic flows through the cut-outs.  The solid central portion of the runner locks the plastic at that area and forces the plastic on cooling to shrink from both ends of the runner towards the center, relieving stress in the combination.  Spacer pins are inserted in the mold adjacent the ends of the runners during the molding process and then removed thereafter to allow shrinkage space between the ends of the holder and the ends of the runner.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method of producing a fibrous mass from peat.         It has not been possible in the past to produce an easily dewaterable fibrous mass from peat when using in the production a continuous process which (1) could be carried out with a minimum amount of manpower, (2) enables a higher yield from the peat moors than had been the case before, (3) enables an efficient separation of colloids and particles smaller than 0.2 mm, and (4) enables the use of a simple equipment which, by a quickly made replacement of a screening member, can be changed to match the nature of the digged-up peat.         The object of the present invention was to obviate this problem which, according to the invention is realized substan-tially by the features that, after a primary sorting operation, the peat material suspension is liquid-concentration regulated by supplying thereto an amount of liquid depending on the degree of humidification of the digged-up peat, and then supplying the suspension under pressure to at least one screening member having a permeability depending on the peat-fibre concentration of the peat material after said concentration regulation.

Abstract: ELECTRICAL CONTACT WITH TORSION BARS                 ABSTRACT OF THE DISCLOSURE       Disclosed is a female contact of unitary construction employing a torsion bar joined at one end to one of two opposing, spaced apart, elongated contact blades.  The two blades have a relatively high spring rate and are forced apart when a male contact is inserted between the blades to provide the desired contact retention forces.  One of the two contact blades is oriented edgewise with respect to the plane of a rigid opposing blade to provide a high spring rate in the direction of outward displacement.  The outward displace-ment of the edge-wise-oriented blade and hence the contact pressures applied thereby to the male contact are primarily a function of the torsional characteristics of the torsion bar to which it is joined.  If desired, this contact pressure may be essentially doubled by providing two juxtaposed edgewise-oriented contact blades, each joined to a respective torsion bar.

Abstract: ABSTRACT OF THE DISCLOSURE    A specific binding assay method, and a test device and test kit for use therein, for determining a ligand, such as an antigen or antibody, in, or the ligand binding capacity of, a liquid medium, particularly a body fluid such as serum, wherein the unknown ligand competes with a labeled component, such as a radiolabeled form of the ligand or of a binding analog of the ligand, for binding with a binding partner, and wherein separation of the resulting bound-species and free-species of the labeled component is accomplished by allowing the liquid reaction mixture to be drawn by capillary action into a column comprising a bed of an adsorbent material selective for one of the two species.  The improvement comprises using a column con-taining at least one additional bed of capillarily absorbent material disposed above said adsorbent bed and which is sub-stantially nonabsorbent relative to the one of said two species which said adsorbent bed selectively binds.  The use of speci-fic types of capillarily absorbent beds in addition to the selectively adsorbent bed to form multilayer columns overcomes several unforeseen problems encountered in using the pre-viously known column chromatography method for certain assay applications.
