Abstract: An allergy testing system comprises a skin test device having a grip portion for holding the device. One or more legs extend from the grip, and each leg is oriented to interact with a well containing a potential allergen. Each leg has a test head, and each test head has a plurality of elongated spike members. The elongated spike members have a sharp end configured to receive the potential allergen from a well and to puncture a patient's skin. In addition, each test head has a touch activator. The touch activator is longer than the plurality of elongated spike members, such that during an allergy test, the touch activator comes into contact with the skin prior to the elongated spike members, causing the touch activator to activate nerve tissue that blocks transmission of pain, resulting in a reduction of pain and/or discomfort during testing.

Abstract: Embodiments of the invention are directed to a skin testing-device system. The system includes a tray, a well holder that snaps into the tray and that holds a plurality of rows of test-solution wells, and a well holder-assembly lid that snaps into the tray over the well holder. The well-holder may include see-through windows such that a test-solution level is visible for substantially each of the test-solution wells from one or more single viewpoints, which may be elevated, and offset, from the well holder. The well holder-assembly lid may include areas that prevent skin-test devices in the test-solution wells from being dislodged from the test-solution wells while the well holder-assembly lid is snapped into the tray. Embodiments of the invention are directed to a clamshell-package system for holding skin-test devices. The system includes a clamshell package having generally crescent-shaped receptacles in an offset pattern and a clamshell-package lid.

Abstract: A solution or dispersion of polystyrene is used to treat the submergible surfaces of fiberglass boat hulls to prevent or alleviate blistering. With newly constructed fiberglass hulls polystyrene paint is applied either directly to the fiberglass surfaces or to a gelcoat protective surface applied over fiberglass. In the case of existing fiberglass hulls on which blisters have formed, the blisters are excised, filled with an epoxy resin or other fairing compound and ground smooth. Polystyrene paint is applied either to the blistered areas or larger areas after sanding.

Abstract: A system for making multi-site skin tests primarily for use by allergists making use of a multi-head applicator and a matching multi-well dipwell tray. The applicator has an elongated handle with arms extending transversely from opposite sides having downwardly extending legs terminating in multi-pointed ends or heads capable of picking up and retaining small quantities of liquid skin-testing substances. The multi-point ends or heads occupy the same plane and are arrayed in a pattern suited for simultaneously making multi-site skin tests. The applicator cooperates with a multi-well dipwell tray with a plurality of dipwells arrayed in patterns which match the pattern in which the multi-pointed ends or heads on the cooperating applicator are arrayed. The volume of testing substance or medicament in a dipwell will equal many times the volume of a single dose or increment that is picked up by one of the multi-pointed ends or heads on an applicator.

Abstract: A plastic skin testing and vaccinating needle characterized by an end bifurcated into two sharp points spaced sufficiently close so that the points will form a small hole in the skin when the needle is simultaneously rotated and pressed against the skin. The spacing also causes liquid to adhere to and between the points when the end is dipped in skin testing or vaccinating liquid. The cross-section of the needle shaft is sufficiently large that the needle can be readily rotated between a user's thumb and index finger. Rotation is facilitated by altering or roughening the surface of the shaft so as to reduce slippage during rotation. Preferably, the needle is formed in a die produced by electro-discharge machining so as to have an etched or matte surface which enhances the adherence of liquid to the bifurcated end.

Abstract: A dipwell tray for a variety of liquids to be selectively applied by sharp pointed needles to a person's skin. For example, the liquids may be antigens used in skin testing for allergies. The tray has a number of so-called dipwells with co-planar mouths or top openings. In use, the liquids are introduced into the dipwells and the needles are then inserted into the dipwells, making the set-up loaded and ready for the needles to be removed one-by-one with liquid adhering to their sharp points. In order to facilitate the removal of the needles the top openings of the dipwells are provided with oriented needle-receiving pockets whereby the needles in the dipwells will be inclined in a desired oriented direction.

Abstract: A pitch changing device or slide bar for a guitar. The device is tubular and the outer surface tapers from an enlarged midportion toward the opposite ends so as to provide a generally convex exterior which allows the player to selectively engage only a single guitar string at a time or any two adjacent strings at a time.

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.
