A magnetic fluid treatment device, including a non-ferromagnetic inner housing disposed within a non-ferromagnetic outer housing, at least two non-ferromagnetic caps to hold the inner housing in place, a ferromagnetic strip external to the inner housing, and structure for creating a magnetic field across the cross section of the inner housing.

A gang tool assembly for drilling a precise pattern of holes in a workpeice or otherwise cutting surfaces and the like on such workpiece and including a mounting panel of rigid sheet material having a pattern of holes formed therein to receive supports for powered tool heads to detachably support the same to form a gang pattern of either drills or cutters for simultaneously drilling a pattern of holes in a workpiece or forming a contoured surface thereon. The mounting panel is formed by at least pricking with pins a pattern of holes upon a sheet-like pattern of all holes to be drilled and forming partial patterns of the entire pattern separately upon said sheet-like pattern and digitizing the same upon a tape for use in a numerically controlled machine operable to successively drill a series of rigid sheet-like support plates for holding powered drill heads in partial patterns of said entire pattern and comprising a set thereof for use to drill patterns of holes in sets of test and base plates respectively requiring holes of different diameters for use in ultimately drilling holes in product sheet material having the entire required pattern of holes therein.

A gang drill head having a row of drills spaced according to repeated patterns of holes in a tubular member such as a suction roll in a paper-making machine which are clogged and are to be cleared by drilling the same, the drill head being guided for longitudinal movement along a guide member positioned upon the roll for circumferential incremental movement to effect radial movements of the rotating drills for the full circumference of the roll and the head including longitudinal adjustment of individual drill supports in accordance with the spacings of the repeated patterns of holes in the roll. The individual drill chucks are rotated simultaneously and manually controlled linkage causes raising and lowering of the drill head by a fluid-operated unit.

A gang tool assembly for drilling a precise pattern of holes in a workpiece or otherwise cutting surfaces and the like on such workpiece and including a mounting panel of cured settable material having a pattern of holes formed therein to receive supports for powered tool heads to detachably support the same to form a gang pattern of either drills or cutters for simultaneously drilling a pattern of holes in a workpiece or forming a surface thereon. The mounting panel is formed by mounting a pattern of pins upon a base mold plate, surrounding said plate with mold sidewalls, placing sleeves upon said pins, pouring a settable slurry of high fracture strength of uniform thickness around said pins, allowing the material to cure to rigid condition, and removing the molded rigid panel and sleeves in situ therein from said base mold plate and pins to provide a rigid supporting panel for a gang of powered tool heads having supports extending through said sleeves. Detection mechanism to indicate broken drills or cutters and/or malfunctioning power heads are associated with the gang tool system.
