Abstract: A gear assembly having a shaft, a clutch assembly mounted to the shaft and moveable between forward and reverse positions, forward and reverse drive gears that rotate independently of the shaft, and a transfer gear assembly. When in the forward position, the clutch assembly engages the forward drive gear so that the forward drive gear rotates in the same direction as the shaft. When in the reverse position, the clutch assembly engages the reverse drive gear, which engages the transfer gear assembly to rotate the forward drive gear in the opposite direction as the shaft. The gear assembly may be used on a bicycle to allow a rider to propel the bicycle forward by either pedaling forward or backward.

Abstract: A modular apparatus for cultivating marine animals caged within rearing units submerged in a body of water of the natural environment of the animals includes a row and column structure that floats at the water surface. The apparatus is moored by anchors deployed at the column ends and at position intermediate the column ends. The members of the rows, and optionally the columns, are constructed from substantially rigid tubes, especially plastic, corrugated wall, culvert pipe, filled with a substantially incompressible foam. The row members are releasably attached between adjacent columns in perpendicular orientation to the longitudinal axes of the columns.Each rearing unit is a perforated wall container suspended from a row member by a suspension assembly so as to hang above the water floor. Multiple rearing units can be suspended from each row member. The rearing units contain vertically oriented panels of substrate material, especially sheets of cementitious backer unit.

Abstract: A clutch operated, bi-directional bicycle gear box assembly for forward and rearward peddling to still move the bicycle forward, comprised of: a gear box housing, the housing attached to the bicycle frame; a pair of foot pedals; a pair of crank arms; a bottom bracket spindle; a sprocket; a sprocket drive gear; a clutch subassembly, the subassembly consisting of a pair of clutch disks attached to a spacer, each clutch disk having a pair of pins; a reversing drive gear; a transfer gear, and; a shifting lever. The housing provides attachment of the components. The crank arms, attached to each pedal and to the bottom bracket spindle, transfer the pedaling motion to the bottom bracket spindle. Once the gear is in the first position, the rider can pedal forward (clockwise) in order to induce forward motion in the bicycle.

Abstract: This invention concerns a device for killing insects consisting essentially of (i) a toxin-containing element, and (ii) a mesh covering for the toxin-containing element of (i) to protect nontarget organisms from contact with the toxin, the toxin-containing element comprising about 50% to 78% of the surface area and the mesh covering comprising about 22% to 50%; and a method for killing insects by exposing them to contact with the described device.

Abstract: A method and apparatus is provided, for separating articles from product boards and transporting the product articles to another processing station or packaging area. Because of the sticky nature of confections which may be handled the product must be scraped from a product board. Articles are separated from product boards on which they rest upon encountering a blade member which acts to wedge the product from a board surface. The boards are ejected from the machine for reuse, while product or confections are moved downstream along a belt take-up transport conveyor for deposit onto product delivery conveyor, whereby product orientation may be accomplished.

Abstract: This invention concerns a device for killing insects consisting essentially of a toxin-containing target element, an optional mesh covering for the toxin-containing element to protect nontarget organisms from contact with the toxin, and a reservoir that is movable relative to the target and cooperating with it to store dead insects; and a method for killing insects comprising exposing them to the described device.

Abstract: An improved device for killing arthropods characterized by a sloped target area that contains a toxicant, the device being devoid of any containment vessel for dead arthropods.

Abstract: A device for combatting troublesome flying insects comprising a sloped target area containing a wet or dry dosage of tetrahydro-2-(nitromethylene)-2H-1,3-thiazine lethal to flies and covered with a closely fitting or flush grill; a hollow base section having a bottom and side or sides; a cavity for the containment and concealment of intoxicated flies; and a means of supporting said target area. In the case where the device contains a wet amount of said insecticide, the device further contains a means of establishing fluid contact between the target area and a fluid reservoir in the base section. Also claimed is a method for combatting flies utilizing the devices of the invention.
