  • Patent number: 7824595
    Abstract: A system and method for insulating an outer surface of a fluid conduit is provided. A portion of the circumference of the outer surface of a conduit is surrounded in a film, thereby forming a generally annular pocket between the outer surface of the conduit and the inner surface of the film. Insulation is deposited into this pocket between the outer surface of the conduit and an inner surface of the film, molded to a substantially uniform radial thickness, and cured to form a cast molded conduit.
    Type: Grant
    Filed: May 25, 2005
    Date of Patent: November 2, 2010

  • Patent number: 4651475
    Abstract: A honing device which employs a plurality of radially-displaceable tools mounted circumferentially around a rotary body. The tools are constructed as a laminate formed by the axially elongated abrasive strip bonded to and overlying a wood backing strip. The abrasive strip has a width, as measured in the direction of rotation, which is normally less than the width of the backing strip. The abrasive and backing strips are radially urged for simultaneous contact with the cylinder wall being honed.

  • Patent number: 4147462
    Abstract: A valve-seat cutting machine having a vertically movable support structure with a vertically elongated spindle assembly mounted thereon. The spindle assembly includes an elongated pilot adapted to be axially inserted into a bore formed in an engine block. A cutting tool is rotatably positioned in surrounding relationship to the pilot rod and is driven from a substantially coaxially aligned driving sleeve, which sleeve is connected to the tool by an intermediate coupling which permits substantially universal movement so that the tool can undergo angular and/or lateral misalignment relative to the rotational axis of the driving sleeve. The pilot rod, which moves angularly or laterally with the cutting tool, is also connected by a similar joint structure to an actuator which permits the pilot rod to be slidably moved relative to the cutting tool. A compression transmitting structure extends through the latter-mentioned joint structure to permit a pushing force to be imposed on the pilot rod.

  • Patent number: 4067701
    Abstract: A grinding machine particularly for grinding the teeth on a carbide cutter. The machine includes a carriage swingably mounted on a frame for oscillation about a pivot axis. The carriage has a grinding wheel mounted thereon and rotatably driven by a motor which is also mounted on the carriage. The wheel is rotatable about an axis which is approximately parallel to but spaced from the pivot axis. A feeding mechanism projects outwardly from the front face of the grinding wheel at an angle of approximately 45.degree. relative to the rotational axis. The feeding mechanism releasably supports a carbide element. The feeding mechanism is linearly advanced toward the grinding wheel in an intermittent steplike movement which is synchronized with the oscillating movement of the carriage so that the grinding wheel cuts a groove across the carbide element during both the forward and return swings of the carriage.
