Abstract: ABSTRACT OF THE DISCLOSURE         There is shown a composite structural member which comprises a pair of stacked wooden board-like elements arranged vertically edge to edge and a pair of wooden plank-like means arranged one on either side of the stacked boards.  The plank-like means extend in the same direction as the elements.  The lower edges of the plank-like means; each of which is the same thickness as the elements, are preferrably positioned in line with the lower edge of the lower element and the upper edges of the plank-like means overlap and extend upwardly beyond the edge to edge line of contact of the stacked wooden elements to a point about one-third of the way up the upper element.  Elements and plank-like means are firmly attached together to produce a rigid structure member.

Abstract: ABSTRACT OF THE DISCLOSURE      A collapsible saw-horse is disclosed, comprising a beam and two frames extending side by side from the underside and longitudinally of the beam, and each forming a pair of legs for supporting the beam.  Each frame consists of a single bent tubular member defining two upright leg portions and an intermediate bight portion at the lower end of the leg portions.  The upper ends of the leg portions are bent back and inserted within brackets secured to the underside of the beam.  One frame is rigidly secured to the brackets by screws extending through the brackets to take a collapsed position parallel to the first frame and an operative beam-supporting position diverging from the first frame.  A pair of pivoted toggle arms link the two frames to prevent the pivotable frame from spreading beyond a predetermined limit angle with respect to the fixed frame.

Abstract: BLOOD SAMPLER                        ABSTRACT OF THE DISCLOSURE   A device particularly suited for collecting and dispensing an arterial blood sample. A needle is connected to a flexible transparent tube that includes an air exit vent with a nonwet filter so air, but not blood, can exit the vent under arterial blood pressure. A special needle adapter prevents formation of air bubbles, and a baffle system in the needle minimizes blood and air mixing. A clamp on the reservoir pinches off an air contaminated blood segment and can longitudinally strip a different blood segment which is not air contaminated. The tubular reservoir has an oxygen blocking coating, and its internal surface includes a dry anticoagulant coating.

Abstract: Abstract of the Disclosure A sealing arrangement for a shutter for a feeding chamber of a continuously operating pressure grinder. The feeding chamber is provided with an inlet opening for feeding wood batches at atmos-pheric pressure into said feeding chamber and with an outlet open-ing for feeding said wood batches into the grinding chamber at over-pressure. Each opening of said feeding chamber is provided with a shutter movable between an opened position and a closed position for preventing of escape of said overpressure through said feeding chamber.       The feeding chamber is provided with a fixed guide supporting the shutter during its movement between opened and closed positions. Said guide comprises two parallel support surfaces between which the shutter is slidably mounted. The distance between said support sur-faces is greater than the thickness of the shutter adjacent said support surfaces so that the shutter is displaceable towards and away from said support surfaces in a direction perpendicular to said support surfaces. A sealing element is provided in one of said support surfaces in such a way that, when the shutter is displaced away from said one support surface towards the other support sur-face, the shutter is released from contact with said sealing ele-ment. In this way the shutter is due to the pressure difference between opposite sides of the shutter pressed against said one support surface and against said sealing element but is released from contact with said support surface and said sealing element when the pressures are equilized on opposite sides of the shutter and can be moved to open and closed positions without said contact.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is an apparatus for chlorination of molten magnesium chloride salts, that comprises a shell lined with a refractory material and having the interior thereof formed by walls, a bottom and a cover. The lower portion of the shell walls is provided with chlorine inlet means whereas the upper one has a melt feed inlet device and a chlorinated melt outlet means. The interior of the shell is so tapered downward that its clear opening at the level of the chlorine inlet means is not over 0.3 times that at the level of the melt feed inlet means and the chlorinated melt outlet means.          The construction claimed provides the activa-tion of the chlorination process throughout the apparatus volume, allowing an unrestricted increase of the apparatus capacity.  Furthermore, the recommended arrangement of construction elements rigidly linked with the apparatus shell increases the continuous-operation time of the chlorination furnace under aggressive media conditions.
