Abstract: A hole cleaning device which may be attached to the top of an auger or auger extension for rotation therewith includes two diametrically opposed blades arranged to resemble one flight of an auger, the outside diameter of the blades being suitably larger than the hole-digging auger itself. The two blades are secured to a mounting sleeve adapted to be secured to the upper end of the auger tube which supports the auger or to the top auger collar. To the top sides of the two blades are secured two elongated and radially extending deflecting elements, these being arcuately shaped and upstanding. As a hole is being drilled into the soil, the displaced soil is lifted and deposited onto the surface of the ground in an area around the hole. When the hole is drilled to full depth, the cleaning blades engage the soil build up, lifting and throwing it radially outwardly. For slow auger speeds, the loose soil is stacked in an annular pattern spaced from the hole.

Abstract: A method for the die casting of end rings and conductor bars in rotors employing a die casting machine having a compensator mechanism comprising a compensator sleeve and a compensator for reciprocal movement along a first axis. A coaxially movable die plate closes off one end of the compensator sleeve to form a die cavity for casting. A plurality of lamination stacks, each held together by a removable stacking pin, are stored on an inclined loading rack positioned laterally on one side of the compensator mechanism. A few of these stacks roll down inclined planes into the compensator sleeves. The compensator pushes the stacks forward into abutment with the die plate and a charge of molten material is injected into the die cavity. The die plate then moves axially away from the compensator and a retriever moves perpendicular to the first axis to an unload position between the compensator sleeve and die plate.

Abstract: A method for transferring a workpiece fixture from one supporting table to another in an air float system. The workpiece is mounted to a workpiece fixture, which in turn is supported on the upwardly facing surface of either a stationary air float table or a movable air float plate. The movable air float plate, which may be mounted on a vehicle, such as a forklift, or itself supported on a cushion of pressurized air, is moved into abutment with the stationary table. The air float system is then activated so as to establish a cushion of pressurized air between the fixture and its supporting surface, and the fixture is slid from one surface to the other on the cushion of air in a substantially friction-free manner. The movable plate or table is then retracted away from the stationary table and the workpiece may be positioned thereon for machining or any other operation which is desired.

Abstract: A tone generation system intended primarily for use in electronic musical instruments wherein a digital representation of a harmonically rich waveform is sampled, and a musical tone is produced therefrom. The stored waveform could be the four term Blackman-Harris window function, which has negligible side lobes and thus greatly attenuated higher harmonics. The stored function is read out at a fixed rate, but the time periods between successive readings of the waveform are varied to thereby vary the frequency of the output signal.
