Abstract: A game call having a striking member and a body member, the body member forming an enclosure about a central cavity and having a pair of opposing edges defining a longitudinal opening that is contiguous with the central cavity. The body member has an inner surface and an outer surface, with a scalloped surface extending from the outer surface adjacent each of the opposing edges. The striking member is engaged against the body member in combinations of striking actions and sliding actions along one or both of the scalloped surfaces to create sounds similar to rattling antlers of antlered game.

Abstract: Methods are disclosed by which wooden railroad ties are pre-plated prior to use in constructing and/or repairing railroad lines. Methodology disclosed comprises placing two plates on top of each of a succession of wooden ties, temporarily positioning disclosed one of the two plates on each tie with a distance or spacer template temporarily clamping the two plates accurately to the tie using a jig, starting a field spike and a gauge spike (usually with one or more sledge hammers) into each wooden tie through the selected apertures in each plate, and further driving the started spikes into the associated tie (usually using a jackhammer). Typically, the field spike is located outside the field flange of the plate and is driven until the head of the spike is contiguous with the plate. Typically, the gauge spike is displaced through an aperture in the gauge flange of the plate until the head is about 1½ inches above the plate.

Abstract: Enabled or activated closure and sealing devices in the form of closure balloons, and related methods, are disclosed, which substantially preclude entry and clotting of blood at the distal end of a lumen of an indwelling catheter tube during times when flow therein is not occurring. The closure and sealing balloon is disabled or deactivated to accommodate flow, without clotting, through the lumen of the catheter tube when flow therein is resumed.

Abstract: This disclosure relates to a centrifugal vortex system for preparing a liquid, such as fuel and includes a chamber housing defining a vortex chamber. An array of tangential apertures are formed in the chamber housing to permit fluid to be turbulently introduced into the vortex chamber to create a vertical flow of fluid through the vortex chamber. In one embodiment, a plurality of vortex chambers are arranged in series to allow the fluid to pass through several vortex chambers. In other embodiments, the chamber housing may be stepped, textured, or both to increase the turbulence of the flow through the chamber. In yet another embodiment, a pressure differential supply jacket is provided to normalize the amount of flow through the tangential apertures according to the location of the apertures. A centrifuge chamber is also disclosed which has a plurality of output conduits on a bottom surface and a tapered extension member downwardly extending from a top surface to enhance the centrifugal flow of the fluid.

Abstract: This disclosure relates to a centrifugal vortex system for preparing a liquid, such as medicine, and includes a chamber housing defining a vortex chamber. An array of tangential apertures are formed in the chamber housing to permit fluid to be turbulently introduced into the vortex chamber to create a vortical flow of fluid through the vortex chamber. In one embodiment, a plurality of vortex chambers are arranged in series to allow the fluid to pass through several vortex chambers. In other embodiments, the chamber housing may be stepped, textured, or both to increase the turbulence of the flow through the chamber. This present invention may be used for nebulizing and vaporizing fluids, powders and liquids for inhalation by a patient.

Abstract: An adjustable game call apparatus includes a sounding board, an air passageway formed in the sounding board, and a vibrating reed positioned within the air passageway adjacent the sounding board. A pair of guide posts extend upward from the sounding board to receive a pair of cut-out areas formed in the reed. The slots and posts allow the reed to be longitudinally adjustable relative to the sounding board of the game call apparatus. Another aspect of the game call apparatus comprises a moisture diverter system which involves a plurality of diverters formed in the sounding board to direct moisture away from the reed and toward a trough formed in the sounding board. The diverters also provide a precision tuning system for the game call to ensure the full high and low ends of the desired range of tones are produced by the game call.

Abstract: A feathered game call apparatus that simulates the wing sounds of a game bird. One preferred game call comprises an array of feathers and a handle having a gripping portion for manually manipulating the call and a feather-receiving area. The array of feathers is sequentially grouped and nested closely together so as to resemble an actual wing of a game bird. Each feather comprises a stem end and a tip end. The feathers are arranged generally in a spaced relationship in a common plane. The stems converge toward a common point of intersection at the handle, and diverge outwardly away from the handle to form a plurality of acute angles with respect to each other. The feathers are flared outwardly in a cantilevered, sequential, fan-shaped, nested fashion from the handle. An end feather may be turned inwardly to simulate the make-up of an actual wing of a game bird.

Abstract: Novel point-of-purchase cantilevered deflectable display assemblies, which normally extend transversely into a shopping aisle. Display assemblies which accommodate substitution of one frame-carried form or configuration of advertising for another, which can be radically different, without disconnecting the entire display assembly from its mounting to a molding at a store shelf or like. The advertising frame with which the advertising medium is associated is removably connected to a hanger portion. The hanger portion accommodates the above-mentioned on-site frame and advertisement removal and exchange while the remainder of the display assembly remains in its shelf-mounted or like position. Display assemblies are disclosed which enhance the deflectable nature of the cantilevered distal part of the display assemblies, the manner in which pivoting occurs and is controlled or limited and the way in which the display assemblies are biased toward neutral in the assembled condition.

Abstract: The novel snowshoe (400) includes at least one tail extender (404) to provide variable flotation characteristics and traction bars (412) that provide improved side slip protection such as when traversing steep terrain. The snowshoe (400) is thereby especially advantageous for use in back country mountaineering. A three (or more) point attachment mechanism is disclosed for coupling the tail extender (404) to the flotation plate (416) of snowshoe (400) so as to reduce stress on the coupling elements and provide a more secure interface.

Abstract: A catheter atherotome and method for its use for performing partial atherectomy in an artery and thereby enlarging the lumen effectively available for blood flow through the artery. Several blades are mounted at a distal end of a catheter, in a helical basket configuration and spaced angularly apart from one another about the associated ends of two concentric sheaths in such a way that longitudinal and rotary relative movement of the sheaths selectively bows the blades arcuately outwardly into a cutting position or draws the blades flat into alignment with the sheaths. The blades have sharpened cutting edges extending helically and directed toward the catheter's proximal end when the blades are bowed. Partial removal of an atheroma is effected by manually pulling the basket knife past an atheroma with the basket blades in their outwardly bowed cutting positions, with the speed, force, and amount of expansion of the blades determined by the operator.

Abstract: A compound bow carries eccentrics, each of which has a non-circular string groove with a geometric center removed from the axis of the eccentric and a take-up groove which is out of registration with the string groove about substantially the entire peripheries of the grooves. The two grooves are carried by respective sheaves rotatably joined through a hub which is itself rotatably connected to one of the sheaves. Other aspects of the present invention relate to a unique idler used in combination with a single-cam embodiment of the present invention.
