Abstract: A plastic barrier screen that is molded and drawn; the screen is formed from a process that uses the speed of injection molding to form a part that can be mechanically oriented in a second operation that is equally fast. The plastic barrier screen is first formed from injection molding a part with multiple square or hexagonal holes ½ to ? opening size in a uniform pattern, including longitudinal dividers between such holes of 2 to 6 times the final desired screen barrier cross sectional area of the longitudinals respectively. The molded part is then stretched along the longitudinal elements of the mold to molecularly orient at elevated temperature to produce a larger planar dimension of 2 to 6 times the original plastic screen with high strength molecularly oriented monofilament longitudinal elements.

Abstract: A rod and reel assembly for deep water fishing. The rod employs a structure that eliminates the need for line guides along the length of the structure by use of a swivel guide that maintains the line between two rod members. The swivel roller is placed at the distal end of the structure allowing fishing line deployed from a mounted reel to the swivel roller to pass unobstructed through the structure. Also disclosed is an electric reel that includes a cantilever spool having an enlarged interior allowing hand control of free spooling. A two stage drag system employs a first set of springs to allow hands free spooling with minimal drag and a second set of springs for proper setting for the fish hauling.

Abstract: A fish cage formed from a molecularly oriented single strand filament that is crossed and welded at the intersections to make a net or screen configuration. The filament being molecularly oriented by stretching ratio of about 3:1 and has a cross section of the filament being at least 2 mm2. The filament is an extruded thermoplastic material made from nylon, polyester, polyethylene, polyurethane or polypropylene having a preferred cross section in a D or oval shape to better facilitate welding the intersections. An antimicrobial or biocide may be added to the filament. The screen or net is preferably of a bright color such as yellow, green, white or a translucent white. The screen can also be formed by connecting small injection molded segments together thereby producing a larger screen.

Abstract: A breathing apparatus for providing pressurized air to a swimmer. The breathing apparatus is based on a geometrically shaped structure that provides superior floatation characteristics in all sea conditions. The breathing apparatus includes a spherical shaped buoyant housing that is mounted above a half spherical shaped submersible housing. The buoyant housing provides a reservoir for pressurized air that is delivered to one or more swimmers by use of flexible air hoses. A battery powered air compressor and motor to produce the pressurized air is positioned within the submersible housing. An air intake for the air compressor receives air by a snorkel, the snorkel stores in a second position suitable for use as a handle while towing the apparatus on wheels. A rechargeable battery is positioned within the submersible housing to power the air compressor with cycling provided by use of a pressure switch. The rechargeable battery and air compressor operate as ballast within the submersible housing.

Abstract: An improved liquid pump for transporting live fish or other products in an induced flow has secondary line with one end to be placed in a pool of liquid containing fish or other products. The other end of the line is connected to a housing having an internal pump chamber. A primary intake has one end connected to a reservoir of liquid and the other end connected to the housing concentrically about the secondary line. As liquid flows through the primary intake into the pump chamber and out the outlet, the Coanda effect results in a low pressure area in the pump chamber. The liquid in the secondary line is induced to fill the low pressure area. By shaping and directing the primary intake and the secondary intake within the pump chamber a more efficient pump is produced.

Abstract: The underwater lighted fishing lure utilizes a two-color lighted system (blue, green, blue-green, white) which either blinks two LEDs ON and OFF (cyclically or randomly) or includes laterally extending fins causing the underwater lighted fishing lure to spin or rotate due to current flows thereby flashing colors from a certain perspective underwater. Light emitting devices (LEDs) maybe driven with excess voltage or current (above 3.5 volts) by 2, 3 or 4 lithium batteries or 3 or 4 alkaline batteries. To modify the beam of light from the LEDs, light modifiers, light diffraction gratings and light reflection surfaces disperse the light laterally away from the elongated housing. Chemical lights of different colors with laterally extending fins are spaced apart to facilitate breakage and activation of chemical capsules. A clip system with a double spring action includes a U-shaped clip at an end of an O-shaped body.

Abstract: The underwater battery powered lighted fishing lure includes, in one embodiment, a transparent housing, a battery in a battery cavity and one light emitting device (preferably, an LED). The battery may have a substantially light reflective surface. The transparent housing has light refraction surfaces, may have one or more light modifiers (glitter, bubbles, glass beads). As a result, the fishing lure emits light in all three dimensions (x, y and z) due to light refraction and light reflection (from the battery). Preferably, the lighted fishing lure includes two LEDs and two offset batteries. The lighted fishing lure may further include a pressure sensitive switch. In one embodiment, the lure has at least a two way control (ON-OFF) and in another, a three way control (ON-OFF- and ON when the ambient pressure exceeds a predetermined pressure underwater).

Abstract: A longline fishing system which is attached to a fishing boat for the purpose of lessening wear and ear on the fishing line has an improved reel and an auxiliary hauler. The reel is made from a plurality of arcuate sections forming a core. End plates are attached to each end of the core. The diameter of the core and the diameter of the end plates are related to prevent over stressing the line. The auxiliary hauler is placed between the stern and the reel to accept a portion of the hauling load.

Abstract: The underwater lighted fishing lure includes, in one embodiment, a transparent housing, two or more batteries and two LEDs of different color. Studies have shown that the use of two color LEDs in a single lure greatly enhances fish catch. Another embodiment drives the LEDs with a voltage at or above 3.3 volts. An additional embodiment uses lithium batteries. A further embodiment drives the LEDs at or above 150% the recommended voltage or current. Studies have shown that driving LEDs at higher voltages significantly increases fish catch. Additional features include a blinking circuit for the two color LEDs and a planar wing to either the battery powered fishing lure or a chemical luminescent fishing lure which causes the lure to turn based upon underwater flows and currents. This turning simulates a color ON and OFF cyclic operation.
