Abstract: ABSTRACT OF THE DISCLOSURE     Trolling apparatus including a weighted down line and a bracket adapted to be engaged to the down line at any point thereof, the bracket being capable of receiving lead lines, or having a release assembly for a separate fishing line.  Means are provided to hold the fishing line until a predetermined pressure is reached and to release the fishing line without abrasion thereof.  Provision is made for a modified form of the invention in which the release assembly is pivotally mounted to provide for upward and downward movement of the fish.  Abrading of the fishing line is avoided in that the release assembly includes a pivotable pin about which the line is wrapped.  The pin is frictionally held against pivoting until a fish strikes at which time the pin pivots and releases the fishing line.

Abstract: ABSTRACT           Fish are oriented by laying them in random arrangement in the central portion of a vibrating trough, the opposite ends of which form passages slightly wider than the widest fish being sorted.  Fish move headfirst toward the trough ends, and the movement of fish discharged in single file from such trough ends is accelerated to propel fish past detector means.  Such detector means include a radiant-energy source and fish-sorting means responsive to energy from such source operable to deflect fish leaving such source for channeling the fish corresponding to a characteristic detected by the detector.  Such characteristic may be sex, length or sidewise orientation.

Abstract: ABSTRACT       An element for use in forming a deck for a grading or dewatering screen is formed by casting an elastomeric material such as polyurethane into a mould so that a smooth sheet of the material is formed in a liquid state in the mould, lowering into the liquid elastomeric material a substantially rigid open-work reinforcement, such as a perforated metal plate, and an array of studs for forming apertures in the screen element, the studs extending through the openings of the reinforcement and through the elastomeric material substantially to the bottom of the mould, allowing the elastomeric material to set, and then withdrawing the studs from the set sheet of elastomeric material.  This provides a screen element comprising a sheet of elastomeric material having a rigid reinforcement embedded therein and a plurality of grading or dewatering apertures extending through the elastomeric sheet, the apertures being aligned with the openings in the reinforcement.  Preferably the reinforcement has pro-jections, such as flanges, extending substantially perpen-dicularly from it and from the rear face of the elastomeric sheet on at least two opposite edges of the element.

Abstract: ABSTRACT OF THE DISCLOSURE           A hollow mixing bar having at least one blade pivoted at one end by attachment to the mixing bar such that it is de-signed to rest against the mixing bar until the mixing bar is rotated,  As the mixing bar is rotated the unattached end of each blade moves away from the plane of the mixing bar thereby contributing to the blending or decompaction action of the mix-ing bar.  The blade can also protect apertures in the mixing bar used for introduction of fluid materials through the mixing bar and the outlet apertures.  The design of the mixing bar is especially advantageous in that it minimizes the initial torque necessary to blend or decompact solids and is readily removable for cleaning.  In the preferred embodiment the mixing bar pro-vides a wide range of blending action ranging from gentle vi-bration to violent agitation.

Abstract: CONTACTLESS MAGNETIC SWITCH            Abstract of the Disclosure A contactless magnetic switch is provided by utilizing at least one pair of hollow elongated tubular magnetic sensing elements which are each threaded with at least one sense wire and a movable permanent magnet which is positioned adjacent and over the sensing elements. The magnet has two straight edges which in a nominal zero position of the switch extend along the longitudinal axes of the sensing elements, prefer-ably for a distance which is slightly longer than their lengths. The magnet is carried in a revolvable or otherwise movable carrier. If the carrier is revolvable, the magnet may be shaped as part of a circular disc and the two tubes may have their longitudinal axes disposed at an angle relative to each other so that when the permanent magnet is rotated in one direction from the initial zero position, one of the sensing elements will lie com-pletely under the magnet while the other will be removed from the magnet and not affected by it. Thus, the sensing element under the magnet will be substantially completely saturated, thereby providing a low output voltage on its associated sense winding while the other sensing element will be sub-stantially unsaturated thereby supplying a high output voltage on its sensing winding. As the permanent magnet is rotated in one direction or the other over the sensing elements, a sharp transition of the saturation state of the sensing elements provides the desired switching function.
