Abstract: The attached disclosure is directed to a fishing rod handle assembly onto which a reel and a rod portion can be simultaneously, or individually, clamped by virtue of a combined actuating mechanism. The rod section is secured to the handle by a collet having a socket into which the butt portion of the rod section is received. The peripheral wall of the socket is selectively compressible radially inwardly against the butt portion of the rod section by a camming interaction between the collet and collet nut threadably received on the handle. A clamping pawl is pivotally attached to the rear of the collet and extends from the collet to an offset reel seat on the handle where it is adapted to embrace the toe of a reel mounting foot upon selective rotation of the collet nut. In one embodiment of the invention disclosed, the collet nut and the collet also interact to provide a positive disengagement of the clamping pawl from the reel.

Abstract: A process for extracting copper from a copper-containing concentrate by comminuting the concentrate in the presence of a liquid dispersing agent which inhibits agglomeration and forms a pulp, and leaching the pulp in the presence of a silver catalyst.

Abstract: A bottle gripping apparatus having laterally spaced frame plates. The frame plates are pivotal and axially slidable on a mounting pin that may be secured to a supporting bar, or the like, on a conveyor means. A pair of first class lever arms are pivotal on a fulcrum extending between the frame plates in spaced relation below the mounting pin, and a first end of each lever arm presents a gripper jaw -- the two gripper jaws being movable toward and away from each other by pivotal movement of the lever arms. A spring means is operatively connected between said second ends of the two lever arms biasingly to urge the two gripper jaws toward each other. A pair of links connect the second ends of the lever arms to a common control member that is mounted on the frame plates to be axially translatable with respect thereto.

Abstract: A method for carrying out reactions of the Friedel-Crafts type, such as alkylation, acylation, polymerization, sulfonylation and dehydrohalogenation. The reactions are catalyzed by arene-metal tricarbonyl complexes and when the reaction vessel contains aromatic substrates the catalyst may be generated in situ from a metallic hexacarbonyl. The arene-metal tricarbonyl catalyst is more selective than conventionally employed Friedel-Craft catalysts in that it yields generally para isomers with little of the ortho variety and very little if any of the meta variety when the aromatic substrate is reacted with organic halide. It is also possible to form the arene-metal tricarbonyl catalyst outside of the reaction vessel and then proceed by adding it to the vessel containing the substrate and the organic halide as is the case with dehydrohalogenation reactions wherein there are no aromatic rings available, the substrate in that instance being aliphatic.

Abstract: Disclosed is a heating unit consisting of a boiler chamber in which a two-phase liquid system is placed under a slight vacuum and supplied with a source of thermal energy. The activation of the source of thermal energy causes the lower phase liquid to vaporize and percolate through the upper phase liquid and circulate into a radiator section made up of finned tubes with an air flow being directed thereacross. The air flow absorbs the heat of the vapor which then is directed to the areas to be heated. The vapor continues to circulate into a header where the vapor is condensed back to the liquid state by a plurality of finned condensation tubes inside the header. The finned tubes of the radiator section have 90.degree. elbows extending upwardly into the header to prevent any condensed liquid from returning into the radiator of the system, and directing the vapor toward the coldest side of the header so as to enhance the condenation process.

Abstract: The invention described herein relates to a device for use with measuring instruments having a movable plunger, such as dial gauge indicators. The device includes a body carrying a slidable member, a shoulder element movable within the body and a suitable means for mounting the body to the measuring instrument. In operation, selective movement of the slidable member limits the amount of plunger travel to a fixed distance. The device may be utilized with different adapters to vary the measuring capabilities of the instrument and at least one novel adapter is described herein.

Abstract: Disclosed is a guidance device for the alignment of two separate objects at least one of which is movable with respect to the other such as, towing and towed vehicles, boats with a dock or trucks with loading docks. The device includes a flexible line connectible between desired points on the objects, such as the trailer hitch and the drawbar of the trailer, and means mounted on one of the objects for drawing in the line as the first object moves toward the second. A sensing means detects changes in the alignment of the two objects and an indicating means signals the changes to the operator whereby alignment may be determined and maintained. Additional indicating means may be provided to enable the operator to check the operability of various electrical components on board the vehicles.

Abstract: A ballcock assembly in which a sheath extends upwardly through the fluid within a reservoir tank to support a valve mechanism above the normal level to which fluid will rise in the reservoir tank. An inlet tube which connects a fluid supply line to the valve mechanism extends through the sheath and is wholly isolated from the fluid within the reservoir tank by the sheath. The outermost lateral dimension of the inlet tube and the innermost lateral dimension of the sheath are such that the inlet tube is completely circumscribed by an air space comprising a passageway that extends the full axial extent of the inlet tube between its effective connection to the valve mechanism and its effective connection to a fluid supply line. The passageway is required to communicate with atmosphere at a level beneath the fluid in the reservoir tank and may also communicate with atmosphere at a level above the normal level to which fluid will rise within the reservoir tank.
