  • Patent number: 4114485
    Abstract: An apparatus is disclosed which is useful in cutting and beveling selective lengths of plastic pipe. The apparatus is supported on the pipe by reason of a closed frame which is releasably locked around the pipe. Rollers are provided in the frame for contacting the pipe. A roller slide is selectably positionable within the frame at a finite number of radial positions. The roller slide serves to adjust its rollers to accept and support the frame on the standard pipe sizes. Opposite the roller slide is a cutting and beveling blade which is radially adjustable into the center of the closed frame.

  • Patent number: 4110676
    Abstract: A speed sensing tachometer is built into the end bracket or end bell of a variable speed dynamoelectric machine such as a DC motor. The tachometer is completely recessed and close to the bearing supporting the shaft to occupy a minimum of longitudinal space in the machine. Multiple poles are provided on the rim of the tachometer rotor fastened to the machine shaft and these poles cooperate with first and second Hall effect switches. An electrical circuit is also provided in the same recess in the end bracket and connected to the Hall switches so that the output from the stator of the tachometer includes both a digital and an analog signal output with rotational direction sensing. Such built-in tachometer permits the DC motor to be a double shaft extension motor so that a load, fan or brake may be mounted at each end.

  • Patent number: 4102199
    Abstract: A method of measuring temperature utilizing resistance temperature detectors (RTDs) is disclosed. A number of RTDs are sequentially scanned and their resistance values are processed by zeroing and linearizing circuit techniques so that an output signal directly proportional to the temperature of each RTD is obtained.

  • Patent number: 4100961
    Abstract: A foundry molding machine is disclosed wherein a core or mold is molded from moldable material such as sand in first and second mold boxes having a cavity. The cavity is filled with the sand and is then cured to form the mold. The first and second mold boxes are separated so that the mold remains in the first mold box with a downwardly facing cavity. Any of several means may be used to assure that the mold remains in this downwardly facing cavity. A transfer conveyor is then moved to a position closely beneath the mold. The first mold box is then moved upwardly as ejection means acts on the mold to eject it downwardly onto the closely spaced transfer conveyor. The transfer conveyor then moves out from underneath the first mold box to remove the completed mold and the cycle repeats.

  • Patent number: 4080281
    Abstract: An apparatus for making metal films comprises an air tight chamber; a rotatable cylindrical cage to receive substrates therein, said rotatable cage constituting an anode; and cathode means of sputtering metal material disposed coaxially of said rotatable cylindrical cage. When a sputtering power source such as DC power source or asymmetrical AC power source is applied across the cage and the cathode of sputtering metal material, metal atoms are sputtered from the cathode means and then deposited on the substrates in the cage. The cage may have partitions or radial walls provided in a circumferential direction about the axis of rotation, so that the substrates may be received in the cage in a separate manner. Alternatively, the cage may be open at the inner periphery and in this case, the cathode means may be disposed inside of the cage.

  • Patent number: 4074507
    Abstract: A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated. This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station. Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate. The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station. An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible.
