Abstract: A cutting tool assembly adapted to be coupled to a cutter head for manufacture of a gear. The cutting tool assembly includes a cutting insert and a holder adapted to couple the cutting insert to the cutting head. The holder includes a pocket defined by a back surface and at least one lip member that provides a force directed against the cutting insert toward the back surface to thereby retain the cutting insert within the pocket during cutting operations.

Abstract: A composition and apparatus and method for aqueous spray conditioning of scale on metal surfaces. An aqueous solution having a base composition of an alkali metal hydroxide is used. The aqueous solution may contain additives to improve the performance of the salt. In one embodiment, the solution is used to condition the scale on a strip of stainless steel. The strip of steel is at a temperature between the melting point of the alkali metal hydroxide in anhydrous form and a temperature at which the Leidenfrost effect appears. One or more nozzles is provided to spray the solution, and the heated strip is passed by the nozzle or nozzles where the solution is sprayed on the surface or surfaces of the strip that have the scale or oxide. The invention also includes the apparatus and control thereof for the spraying of the solution.

Abstract: A method and system for spraying scale conditioning aqueous solutions onto opposite sides of a metal strip for scale conditioning is provided. The system includes a housing which defines a chamber through which the moving strip passes on the strip pass line. A nozzle maintenance station is provided which is disposed off the strip pass line. Sets of spray nozzles are provided and the sets are independently movable between the maintenance station and spraying portion on opposite sides of the strip. Thus, each set can be utilized independently to spray a strip or be worked on in the maintenance station without shutting down the line.

Abstract: A composition and apparatus and method of using the composition for aqueous spray descaling or conditioning of scale or oxide on metal surfaces, especially stainless steel strip or the like, in one embodiment, although it can be used to descale or condition oxide or scale on other work pieces such as metal bar, or even discrete objects. An aqueous solution having a base composition of an alkali metal hydroxide, such as sodium hydroxide, potassium hydroxide, or a mixture of alkali metal hydroxides such as sodium hydroxide and potassium hydroxide is used. The aqueous solution may contain certain additives to improve the descaling performance of the salt. In one embodiment, the solution is used to condition the scale or surface oxide on a strip of stainless steel. The strip of steel is at a temperature between the melting point of the alkali metal hydroxide in anhydrous form and a temperature at which the Leidenfrost effect appears.

Abstract: An apparatus and system for manipulating the air temperature within an interior compartment of a vehicle, the apparatus cycles a compressor between an off and on position based upon a temperature reading of the evaporator fins positioned to cool the air of the vehicle. The system employs a control algorithm wherein the evaporator fin temperature of the evaporator determines the operational status of the compressor.

Abstract: A spade drill is provided including a V-shaped drill cutting end and a pair of reaming edges on each side thereof. The reaming edges have a relatively large radius of curvature and generally define a flat portion at the apex of the reaming edges. The junction between the drill cutting end and the reaming edges has a misblended radius.

Abstract: A milling cutter is provided including a tool holder and a cutting tool insert. The tool holder includes a mounting end portion and a cutting end portion. The cutting end portion includes a slot defined by first and second diagonal surfaces provided in an end of the cutting end portion. The first and second diagonal surfaces form a substantially V-shaped pocket for receiving the cutting tool insert. The cutting tool insert includes a substantially flat body member having a V-shaped seat portion and a cutting portion, the cutting portion includes a first cutting lobe and a second cutting lobe. A hole is provided which passes through the body member. A screw hole passes through the cutting end portion of the milling cutter which intersects the U-shaped pocket. A threaded portion of the screw hole is offset from a clearance portion of the screw hole to positively seat the V-shaped seat portion of the insert in the V-shaped pocket of the tool holder.

The cutting end portion includes a slot defined by first and second diagonal surfaces provided in an end of the cutting end portion. The first and second diagonal surfaces form a substantially V-shaped pocket for receiving the cutting tool insert. The cutting tool insert includes a substantially flat body member having a first side having a cutting surface on one edge thereof and a second identical side having a cutting surface on one edge thereof. A hole is provided through the body member from the first side to the second side. First and second surfaces are provided adjacent and substantially perpendicular to the first and second sides. The first and second surfaces define a V-shaped seat portion for seating the cutting tool insert in the V-shaped pocket of the tool holder.

Abstract: A system for descaling a strip of metal includes a nozzle assembly mounted within a spray box for spraying descaling product on the strip. The nozzle assembly includes a spray chamber; nozzles mounted directly to the spray chamber; and a heater for heating the chamber, the descaling product in the chamber, and the nozzles by conduction through the chamber. The nozzles are oriented to direct the descaling product in a spray against the upper and lower surfaces of the metal strip for an amount and a time sufficient to descale the metal strip. The nozzle assembly is attached to the spray box and can be easily removed therefrom for inspection.

Abstract: An indirect fluorescent luminaire with planar specular reflectors arranged in such a manner as to project its maximum intensity approximately at 130.degree. above nadir to optimize the uniformity of ceiling luminance. The lamps are stacked vertically to further minimize the vertical projection of intensity and enhance the lateral projection. The fixture may be suspended at distances of 12 inches or less from the ceiling without causing excessive luminance on the ceiling above the luminaire or excessive luminance ratios between the brightest area directly over the fixture and a point midway between them.

Abstract: A method and apparatus for improved settling and handling of sludge in a fused salt bath for treating materials is provided. The apparatus includes a tank divided into a work zone and a salt processing zone, with the salt processing zone having a salt recovery section and a salt heating section. A pumping device is provided which together with adjustable gate means, generate a relatively quiescent flow in the work zone allowing sludge to settle, and a relatively turbulent flow in the salt processing zone and especially the salt heating section, to keep the sludge in suspension.
