Abstract: A fish bait (1) is provided in which individual pieces of bait material (2 ) are suspended and evenly distributed throughout a homogenized mixture of bait material and a gelling agent (3), and enclosed in a supporting tubular mesh (4). The fish bait is obtained by mixing bait material with a gelling agent to form a substantially homogeneous mixture, adding further bait material to the homogenous mixture so that bait material is suspended in the homogeneous mixture and extruding the suspended mixture into a mesh tube and subsequently allowing the gelling agent to set. Once set, the gelling agent stabilizes the suspended structure of the fish bait and allows the controlled release and diffusion of attractants. Preferably, the gelling agent is an alginate.

Abstract: The present invention provides a lure that provides a unique undulating motion for attracting fish. The lure is characterized by a body having two heads that when joined together produce a ripple in the body. This causes the lure to undulate when pulled through water. In a preferred form the lure is formed from two halves joined together at a middle point. Each half has a head and a tail. In a non-fishing configuration, the lure body is flat with the heads having an overlapping/crossing relationship. When the heads are joined together in a fishing configuration, a ripple forms in the lure body.

Abstract: A flip float is fishing float comprising a floatation ball having differently, distinguishably colored first and second halves with a shaft extending through the floatation ball perpendicular to the interface between the halves. A stem assembly containing an internal weight and stops on either end of the stem assembly is disposed to slide within the shaft between the stops contained at the ends of the stem assembly. When the float is inverted, the stem assembly shifts from one stop to the other and changes the center of gravity of the float which causes the float to remain inverted. A fisherman can tell at a glance, by noticing which color is out of the water, whether his line has been struck. Attachment of differently colored, reflecting material to the ends of the tube allows the fisherman to shine a light on the float at night to determine whether his line has been struck.

By applying an inward pressure to the protrusion at slotted end of the plate and pivoting the plate, access to the notched stored hooks and their depending lures can be easily had. The casing and plate may be made of a transparent, clear or colored, molded plastic material to permit view of the stored hooks on the plate's notches.

When the box is closed, two pin holes separately provided on the top cover and the bottom tray opposite to the hinges together form a socket to receive a plug connected to a power source, so that power can be supplied to the intermittent-high-voltage generating circuit for the circuit to generate intermittent high voltage on the metal net. Cockroaches entering into the closed box can be killed by the high voltage.

Abstract: This disclosure concerns affixing various seeds, such as grass seeds, to surfaces or cavities of specially manufactured fertilizer carriers formed into various shapes, e.g. star cross-sections, tri-lobe or multi-lobe profiles, or cup-like or similar cavity-containing shapes.

The fertilizer carrier also acts as a nutrient source for the seed while the seed is most vulnerable, i.e. during its emergence from the seed coat and the first few days after emergence. In an alternative construction, a carrier matrix formed of an organic polymer or proteinaceous compound is coated with seeds or other edible fragments to provide a food for birds.

Abstract: An impermeable horse blanket includes mesh material for ventilation of the horse's back while it is covered by the blanket. The mesh material is shielded by a waterproof top cover that protects it and prevents water from wetting the horse while allowing breathing through the openings of the mesh. The front edge of the top cover is attached to the blanket by means of a continuous seam along a front hem that encases a length of plastic piping sufficiently thick to provide a relief structure for raising the front edge of the cover slightly with respect to the blanket and the mesh material.

Abstract: Past exhaust emission control systems have failed to clean the exhaust gas prior to mixing with the intake air. The present exhaust emission control system removes at least a portion of the exhaust constituents from a flow of exhaust gas prior to mixing with a flow of intake air. The present exhaust emission control system includes a control system for monitoring a operating parameter of an engine. The control system interprets the operating parameter within a controller and the controller causes an exhaust valve regulator to move between an open position and a closed position. Thus, the movement of the exhaust valve regulator infinitely between the open position and the closed position defines the quantity of flow of exhaust gas to be mixed with the flow of intake air and controls the emission, especially of NOx, being emitted from the engine depending on the operating parameters of the engine.
