Abstract: A pipetter barrel extension tube, attachable at its proximal end to any one of a variety of pipetter barrels and at its distal end to standard disposable pipetter tips.  The pipetter barrel extension tube serves to extend the length of the barrels and provide sterile access to deep containers while substantially isolating the permanent barrel of the micropipet from damage caused by chemical and radiochemical contamination.          One novel design feature of the extension tube is an air channel designed to minimize dead air volume in the extension tube.  A removable conical insert plug serves to reduce the air channel volume.  Removal of the plug facilitates cleaning and reuse of the extension tube.  The device also includes a distal end segment which, when intact, serves as a space-filler to reduce dead air volume in disposable tips for pipetting small volumes.  When the segment is removed, the extension tube still attaches to the same disposable tips but allows larger volumes of liquid into these tips as required for larger capacity pipetting devices.

Abstract: The invention concerns a procedure for manufacturing paper bags. The paper bags (10) have been provided at both ends with a sewn seam (15) and the paper bag (10) has in its corner a valve aperture fitted with a collar. With a view to avoiding the cutting of separate collar blanks which has to be done manually, and their fitting, the valve aperture and the repeated running of the paper bag blanks through the production line, the procedure of the invention teaches to affix collar blanks to a full width paper web with a given spacing. Hereafter, the full width paper web is run to assume tubular form and cut in fixed lengths whereby the paper bag in tubular form comprises a shell with both ends open and carrying in its corner a collar blank. Finally on the paper bags in tubular form is performed folding of the corner and sewing of both open ends, whereby a finished paper bag (10) is obtained. It is advantageous for collar blank to use a collar blank, furnished with an incision, a collar blank from which a substantially segment-shaped piece has been removed or a collar blank from which a substantially triangular piece has been removed. On the edge of the collar blanks preferably an oblique cut has been made.

Abstract: An exhaust air valve for placement in a ventilation conduit through which air is exhausted from a space to be ventilated. The valve has a casing with a concave seat surface facing upstream of the flow through the conduit and having a central valve orifice. A convex valve element cooperates with the seat surface and when the valve is closed engages the seat surface along a line of contact surrounding the seat. The curvature of the respective surfaces is the same, at least along the line of contact to ensure a tight closure of the orifice by the valve body. When opening, the valve body slides along the curved surface and the upstream surface of the valve body exposed to the flow is also convex to guide the flow toward the center of the orifice. Several embodiments are illustrated including valves with cords for remotely controlling the valve and heat-sensitive tripping mechanisms which automatically close the valve in the event of a rise in temperature above a preset level. The closing movement may be pivotal about a pivotal connection maintaining the valve element in sliding contact with the valve seat or may be a sliding displacement longitudinally of a slot in one of the elements.
