Abstract: A meat cutting pulley wheel is formed with an aluminum body and a cast iron ring bonded to the body rim. The method of manufacture includes machining the ring, preheating the ring and mold, inserting the ring into the mold, pouring molten aluminum into the mold, cooling in the mold and final machining of the ring.

Abstract: A system and method of measuring the concentration of each component of a two component liquid by passing a microwave signal through a flowing liquid sample. A waveguide is used between a microwave source and detector, and a sample tube passes through the central portion of the wave guide.

Abstract: A self-contained system for applying a viscous tapping fluid to a tapping tool at a machining work site independent of any other cutting fluid system. A supply tank, control cabinet and an air actuating nozzle are interconnected to supply the tapping fluid for a timed period initiated by a limit switch, NC signal or manual command for ready adaptation to equipment ranging from a machining center to dedicated tapping work stations.

Abstract: A liquid separator utilizing an endless belt for skimming extraction of oil from a liquid body and doctoring rollers for gathering the oil from both sides of the belt.

Abstract: The combination with an elongate shaft, means in operative engagement with one end of the shaft adapted to apply thrust to the shaft and another means in operative engagement with the mentioned end of the shaft for turning the shaft about its major longitudinal axis, to selectively move the shaft endwise or to rotate the same, together with a lamellate head of a thickness equal or less than a transverse dimension of the shaft, in engagement with and extending beyond the opposite end of the shaft in a plane, that, when the shaft is viewed in elevation, is substantially parallel to the major longitudinal axis and, when the shaft is viewed endwise, is at an angle to such axis; the head having a linearly extending edge and a part each in the plane of head extension, the part projecting away from the mentioned shaft axis to a point beyond the span of a shaft lateral surface and having a shoulder that extends at an angle less than a straight angle to the shaft major longitudinal axis, so that when the head is press
