Abstract: 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 legs of the splash guard. To accommodate the departure from the desired perpendicularity of the legs of the splash guard, a gusset means is provided in the web of the splash guard which permits the web of the one-piece body to be varied from its normally intended size and shape.
Abstract: 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 analyte moeity has the opposite charge polarity.

Abstract: 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 selective vertical movement of the table relative to the support.A simple, selectively manually-actuatable clamp is available to the worker to selectively control whether the product-supporting table will be only rotated about its vertical axis, or will be also movable vertically by selective rotation of the support table.The stand is mounted on a wheeled dolly which permits moving both the stand, and the product supported thereon, to selected locations.
Abstract: An elongated sleeve member having an upper open end and a lower open end, and with an annular flange extending radially outwardly from adjacent the open lower end is affixed to an elongated stem member in a substantially vertical orientation for immersion in a liquid substance held in a vial. A sleeve-like surface extending between the open ends of the elongated sleeve member, and a surface defining the lower end of the sleeve and an outwardly extending annular flange provide means to remove a consistent quantity of a liquid substance, such as a liquid allergenic agent, from a storage vessel or vial, and to transfer the liquid to a receiving scarifier structure, such as a cluster of multiple scarifier points. The outer periphery and upper surface of the flange provide a means for carrying excess liquid, and the flange provides for wiping the excess liquid from the sleeve member and flange prior to dispensing a desired quantity of liquid allergenic agent onto a cluster of scarifier points.
Abstract: A new method for treatment of skin burn is disclosed. A known material, sodium polyacrylate, has been discovered to be useful in the treatment of burns. The method of treatment includes spreading sodium polyacrylate powder as a dressing over the skin burn area, and wetting the powder, such as by spraying with sterilized distilled water until the powder becomes moist. The outer wetted surface of the moistened powder layer dries to provide a parchment like surface. Such a dressing may be maintained in position over the skin burn area for about 2-3 weeks, operating to control loss of water from the body through the burn area, avoiding capillary permeability, and appearing to prevent infection of the burn area. The dressing may be selectively removed or is sloughed off, and is eventually pushed off by the growth of new tissue under the bottom surface of the protective layer. Sodium polyacrylate (PANa) may be used by itself, or mixed with an anti-inflammatory, or with an antibiotic.

Abstract: A variable width tiered display stand, which may be supplied in knocked-down condition, and which may be readily assembled at the site of use, is disclosed.The stand provides multiple tiers, each adapted for support of a box of boxed goods thereon, to provide an attractive means for display, and offer, of goods to prospective customers, while permitting the shopkeeper to easily withdraw empty boxes of goods from the tiers and to insert fresh boxed goods on the tiers as may be required or desired.The stands are preferably made of transparent plastic parts which may be easily fit together, and which do not require additional fastener means for keeping the tiered display stand assembled.
Abstract: Inexpensive, knock-down, furniture constructions, assembled with mating, molded, plastic shells for corners and elbows are disclosed for use in furniture pieces for use by children. The furniture constructions include panel members of inexpensive sheet material. Each corner connector is formed of two mating shells, that are each molded of plastic and which are shaped to provide internally thereof pairs of telescoping pins and sleeves, which frictionally hold the shells assembled after the pair of shells are pressed together. Each corner connector provides at least two socket means, each for receiving a wooden rail with a channel along its length. The panel members are positioned in and held by the channels of a pair of rails. A pin or sleeve provided on at least one of the corner connectors extends through an aperture provided in each panel member, to effect a holding of the panel member in its proper intended position relative to the plastic mating shells and to the channeled rails.
Abstract: An ink fountain for supplying ink to the ink carrying surface of a printing press form roll has an ink receptacle which may be removed from and reinstalled into the press separate from the adjustable support assembly which maintains it in an operative position with respect to the form roll. The adjustable support assembly enables a doctor blade on the ink receptacle to be placed in an optimum position with respect to the ink carrying surface of the form roll. Dam members which seal front portions of the ink receptacle to the form roll are, in a preferred embodiment, formed as part of the ink receptacle assembly and are removed and reinstalled together with the ink receptacle. The dam members may be formed of a relatively inexpensive, resilient plastic material whereby it is more economic to dispose of them and replace them with new dam members rather than clean them.
Abstract: Aliquot segments of a product transport pallet are maintained assembled to form a pallet assembly of a standard size by rigid members and metallic bands, by mutual interengagement of abutting portions of the segments or by rigid members and clips to enable the segments and a divisible cargo of products contained on the pallet to be readily separated or split into segments for ease of transport and/or display at a point of storage or sale.
Abstract: An improved fixture mounting is provided for a cantilevered fixture having a relatively broad base, or rear portion, adapted to be affixed to a support wall or other support surface. The mounting base portion of the fixture is provided with a cavity that is concealed and surrounded by a rearwardly extending wall provided as part of the base of the fixture. Located in the cavity is a first connecting plate having a pair of oppositely positioned flanges that are rearwardly projected, with the first connecting plate and flanges being secured to the fixture that is located forwardly of a support wall that carries thereon a second plate with forwardly projected flanges for support cooperation with the flanges on the first plate, and so that both plates are positioned wholly within the cavity.
Abstract: A new and improved stream former is provided for attachment to the discharge end of a faucet or the like. The stream issuing from the stream former provides a formed, coherent, non-splash, silent, gentle flow. The stream former includes a sleeve-like casing, of metal or plastic, with an upstream attachment means, and a pair of axially spaced inwardly projecting supports defined on the inner wall of the sleeve-like casing, downstream of the attachment means. A transverse, fine-mesh, support screen is supported on the downstream support. A plastic, cup-shaped, molded transverse member is supported on the upstream support. A plurality of transverse, axial flow holes are provided through the apertured transverse wall of the cup-shaped transverse member. A closely woven, non-shedding, foraminous mat of nylon fibers is positioned between said transverse wall of the upper transverse member and the fine-mesh screen support.
