Abstract: A fish hook setting device comprising a cylindrical housing containing a plunger and a compression-type coil spring. The plunger includes a head and a shaft. The shaft of the plunger extends through the coil spring which is positioned within the housing between an annular wall formed in the lower end of the housing and an overhanging edge formed by the head of the plunger. The shaft further includes a notch defining an upwardly directed abutment surface. The plunger may be drawn from the housing so as to compress the spring. When the notch is advanced out of the housing the plunger is advanced to one side of the housing so that the abutment surface may be placed in contact with the lower surface of the annular wall to prevent the plunger from retracting until an additional force is applied to the plunger preferably from a fish taking a baited hook secured thereto.

Abstract: Electrostatic application of a dusting of dry, electrostatically adherable, thermally insulative powder particles over a workface of a continuous metal-casting machine in which the mold surface or surfaces which provide the workface or workfaces revolve in a generally oval course. A dry dusting of protective powdery refractory material is applied to the workface after being entrained in an air stream and electrostatically charged by suitable electrostatic apparatus. The workface to be dusted is electrically grounded for attracting the charged powder particles for adhering them to the workface. The resultant coating formed by the dusting so deposited is remarkably uniform over a substantial area of the workface, a phenomenon explainable by mutual electrostatic repulsion of the dry powder particles being deposited.

Abstract: A bobber and sinker which can be easily attached and detached from fishing lines is disclosed. The sinker is made of a single high density material, such as rubber, in which a slit has been made, to frictionally hold the fishing line. The bobber has an inner segment of high density material and an outer shell of high floatation material. A slit in the outer segment frictionally holds the fishing line. The bobber and sinker can be rapidly attached and detached from a fishing line by inserting the fishing line into the slits. Also, the bobber and sinker may be rapidly and easily positioned and repositioned along the fishing line, and the fishing line is frictionally held without the need for any operations or mechanisms to secure or hold the fishing line in place. Alternatively, to provide a sinker of higher density, the sinker can comprise an outer shell, an inner core of higher density material than the material of the outer shell, with a slit in the outer shell frictionally holding the fishing line.

Abstract: A fishing device used for trolling is shown which employs the force of water, to engage a propeller that turns a shaft engaging a cluster of gears. The gears alternately engage a worn shaft and a spool. The spool retrieves a cable, to which, is attached a spring loaded parachute that applies a resistive drag to the cable. This parachute incorporates a release mechanism to which a fish line is attached. The cable, while being retrieved on the spool, accelerate the lure attached to the fishline. The worm shaft engages a pawl, which is carried in a pawl retainer, which travels along the worm shafts axis thereby moving the spool, which is rotatably mounted on an axle type shaft mounted parallel to the worm shaft, away from the gear cluster. The spool has a cable attached to it and when the spool is engaged in the gear cluster the cable is wrapped around the spool and when it becomes disengaged the force of the water against the parachute, which is attached to the cable causes the cable to unwind.

The rear half is divided into six case slots by a central vertical divider extending from the top to the bottom of the rear half and six sets of guide rails. Extending into the rear half from the back of the container are six leaf springs, one for each case slot.

Abstract: A method for the direct casting of metallic material, such as steel, to produce elongated bodies (2) which can form blanks having a cross-section which corresponds relatively close to the cross-section of the intended products, in which method a metal melt (1'), while at least its outermost layer remains molten, is caused to run from an outlet gate (3) in a molten-metal container (1) and is collected subsequent to solidification. The melt (1') of molten metal which exits from the gate exits together with a metallic body (5) which has substantially the same melting point as the molten metal, this metallic body being passed through the gate (3), inserted into and moving with the molten metal and causes cooling of the molten metal (1') progressively. The metallic body thereby entrains the molten metal at substantially the same speed as the metallic body (5) in what is termed a boundary layer.

Abstract: A stiff lever arm has a tapered end. A slot is located within the tapered end of the lever arm. The slot has dimensions slightly larger than the looped line tie of a lure which allows the line tie to fit within the slot. Once the line tie is engaged within the slot, a manual force applied to the lever arm produces a torque which bends the line tie to the properly tuned position.
