A combined shower splash guard member with a shower curtain holder is provided by a molded, generally triangularly-shaped, and modified, one piece body having two straight legs that intersect at a vertex of the triangle, and a third, web-like leg that extends between the free ends of said first two legs of the splash guard. Means for holding the one piece body to a mounting for the body is provided by an adhesive strip of a length to be secured to the entire outer surface of the two straight leg...

Fluorescence ligand binding assay of a sample containing an unknown amount of ligand is performed by making direct intensity measurements. In an immunoassay the sample is in a solution containing dye labeled analyte and an antibody specific to the analyte. Surfactant, added to the solution in an amount sufficient to form micelles, provides markedly different fluorescent intensity from bound and unbound labeled analyte if the surfactant ions and dye ions have the same charge polarity and the anal...

A stand for aiding a worker, such as a cake decorator, to have selective access from a single work position to all surfaces of the product being worked upon, where the product has multiple tiers of different heights and widths, is provided by a movable product-supporting table that is independently selectively rotatable and/or vertically movable relative to a support for the table. Structure is provided whereby the support table is selectively rotatable about a vertical axis and provides selecti...

A new test substance for use in skin testing for tuberculosis, which substance is produced from Mycobacterium tuberculosis (M.tb.) culture filtrate or bacillary extract. The culture filtrate or extract is first fractionated by means of chromatography. Resultant fractions are then further fractionated so as to produce subfractions which contain at least one M.tb. specific antigen and are substantially free of antigens crossreactive with atypical mycobacteria. At least two of these subfractions ma...

A sutureless closure device which is operable to draw the edges of a wound or incision together. The device comprises two pieces of surgical tape each having an adhesive face. These pieces are secured to the skin on opposite sides of the incision. An anchor for one end of a tie strip is carried by the exposed face of one tape. A slide is secured to the exposed face of the other tape. A tie strip having ratchet teeth on its upper or exposed face has one end secured to the anchor with its other en...

A limited torque cap is provided with a construction wherein a cam ring is located concentrically within a plurality of at least three radial movable jaws, normally biased inwardly and arranged to provide a driving connection with the cam ring until a predetermined level of torque is applied to the ring-jaw connection. A further construction is provided for effecting axial movement of the cam ring relative to the jaw members after a predetermined torque is achieved, whereby to prevent re-couplin...

Large projection screens, of which planetarium domes are typical, may conveniently be made up of a plural of prefinished panels, at least one edge of at least some of which panels overlaps another panel in a lap joint construction so that edges of the panels have a minimal effect upon light directed upon the screen from any angle. Panel edges overlapping another panel are tapered from a generally uniform thickness to substantially reduced thickness at the edge in a relatively short distance comp...

A drainage tubing for wounds, or body cavities, is described. The tubing is placed and retained in the wound site in an improved manner by means of an inflatable balloon positioned in the intact, healthy tissue adjacent the patient's skin, or in the body cavity adjacent a wall thereof. The drainage tubing may also have a second, collapsible bulb portion for aseptic back-flushing of the placement site while the tubing lumen is sealed from the exterior. The specific construction enables a technici...

Basket for stacking in or on top of another identical basket comprising a bottom and side walls, said side walls being substantially vertical and assembled from a number of rod-like elements obliquely upstanding from said bottom to the plane of the basket bottom.

An improved electrical jumper system, for a locomotive consist for hauling trains, is provided by an installation that converts an existing single-headed receptacle, for receiving one end of a non-permanent jumper cable, into a multiple-headed permanent system that alternatively may be used either to receive a cable head from another locomotive unit, as was the previous purpose of the existing receptacle, or to provide a permanently installed jumper cable that assures presence of equipment at al...
