  • Patent number: 6925696
    Abstract: A rotor puller has two arm members, ending at claws, and a jack with an extendible piston. The arm members and the jack are pivotably attached together about a pivot axis. Springs bias the arm members toward each other. The claws are placed over a brake rotor and retained thereon by a pin. After the claws have been placed, the jack is centered and activated to extend the piston towards the claws. The piston forcibly engages a wheel hub while the claws forcibly engage the rotor, pulling it from the wheel hub. Handles on the arm members facilitate placement of the claws over the rotor.

  • Patent number: 4901323
    Abstract: The output of an oscillator stage of a laser system is monitored by a photocell which is coupled to a feedback section to control a Pockels Cell and change the light output of the oscillator stage. A synchronizing pulse is generated in timed relation to the initiation of operation of the oscillator stage and is applied to a forward feed section which cooperates with the feedback section to maintain the light output constant for an extended time interval.

  • Patent number: 4742261
    Abstract: A constant length strut includes an axially elongated body having a fixed attachment point at one end and an attachment point carried at its opposite end and supported for axial movement toward and away from the fixed attachment point. A quartz reference rod is connected at one end to one attachment point and extends internally for substantially the length of the strut. The free end of the reference rod moves axially lengthwise relative to the other attachment point as the strut changes length due to thermal expansion and contraction or tensile and compressive loading. A positional displacement transducer senses this relative movement. An electrical signal directly proportional to the displacement excites a linear actuator connected between the telescopic attachment point and the strut body to provide a corrective displacement to maintain the strut at a constant length.

  • Patent number: 4198887
    Abstract: A julienne cutter tool and method of making are described, the cutter being intended for use in rotary food processing apparatus of the type having an upright working bowl with a vertical motor-driven tool shaft extending up into the bowl. The julienne cutter has a hub engageable with said tool shaft for rotating a horizontal disc-like member carrying a primary blade horizontally positioned at an elevated location above the upper surface of said disc member and extending from a smaller radius region to a larger radius region. An opening defined by said disc member permits the food material which has been cut by said primary blade to move downwardly through the disc member, and a plurality of individual radially-spaced secondary blades located in said opening in respective planes perpendicular to said primary blade neatly slice the food material into julienne strips.

  • Patent number: 4149425
    Abstract: A dual adjustable flange variable speed sheave employs a common sleeve with clamping end caps. Each flange applies pressure to a V-belt through a helical compression spring restrained by one of the end caps, the sheave being symmetrical about the center of the belt. Outboard bearings for the two adjustable flanges transmit their loadings to the end caps, and the flanges have inboard bearings directly engaged with the common sleeve or connected therewith through interdigitating bearing parts.

  • Patent number: 4023247
    Abstract: An adjustable flange for a dry lube variable speed sheave assembly having an unmachined bore is centered on a vacuum fixture. A thin dry bearing material is secured and located axially and radially within the flange bore and the annular space between the thin dry bearing material and the flange bore is filled with a high compressive modulus material such as epoxy. The dry bearing material is maintained flat during the process by the application of vacuum through the fixture. After curing, the completed adjustable flange is removed for the fixture and assembled with the sleeve component of a sheave. In accordance with a variation of the method, the separately formed thin dry bearing material is eliminated and a suitable dry lube material is mixed with the epoxy-like cement prior to injecting the same into said annular space. Following curing, this material becomes the dry lube bearing of the flange.
