  • Patent number: 4607867
    Abstract: A flexible hose is secured to a fitting using elongated strips and band clamps in a conventional manner so as to prevent relative longitudinal movement between the flexible hose and the elongated strips. One end portion of each of the elongated strips is bent back so as to be contiguous to the next succeeding portion of the elongated strip so as to form a shoulder and a recess is formed in the fitting. The bent back portions are seated in the recess and retained therein by a band clamp acting on the next succeeding portion so that relative longitudinal movement between the elongated strip and the fitting is prevented by an abutting relationship between the shoulder of the bent back portion and a shoulder of the recess.

  • Patent number: 4504824
    Abstract: Apparatus for detecting the presence of a tool in a spindle which can be used where automatic unattend operation occurs and it must be known that a tool is in the spindle. For example, if the tool changer on a machining center dropped a tool when transferring it from a magazine to a spindle the machine would continue to operate but machining would not occur. In the invention, air pressure is supplied to a point through a series of holes in the spindle and if a tool is present in the spindle, it will prevent air from escaping. If the tool is absent, air will escape from the spindle or when the tool is not properly seated in the taper of the spindle which will cause the air pressure to drop and to stop the spindle motor and/or provide a suitable indication and warning to the operator.

  • Patent number: 4479397
    Abstract: A ball screw brake and stop assembly having an elastomeric compression pad or elastomer member circumferentially surrounding the ball screw and received in a counter bore of a non-rotating assembly having a bore receiving the ball screw with the pad confined on its outer diameter and at one axial end. A striker member, dimensioned to be receivable within an open axial end of the counter bore, functions as a stop member limiting axial movement of the ball nut. Upon projection of the striker member into the counter bore, further movement of the ball nut causes axial compression of the elastomer member providing resistance to further axial movement of the ball nut. At the same time, radial expansion of the elastomer member, caused by compression in the axial direction, causes the inner diameter of the elastomer member to frictionally engage the outer diameter of the ball screw to break rotation of the ball screw.

  • Patent number: 4473925
    Abstract: A clamp is provided which includes a buckle of high strength material with top, bottom, and side walls defining a rectangular passage. An elongate band is anchored at one end to the buckle and wrapped on itself and passed through the buckle at least twice to define a clamp structure for securing a hose on a conduit.The top wall of the buckle has two integral but discrete locking tabs centrally located and adapted to be bent down about their lines of juncture with the top wall. A chisel-tipped punch is driven radially inward between the free ends of the tabs to force them into the adjacent layer of the band, causing band metal to flow and produce upset interlocks between the band and the tabs outward of the tabs. The ends of the tabs also cause band metal to flow into a bulge between the tabs. The punch tip divides the bulge and flows the metal toward the tab ends to produce a second pair of upset interlocks between the band and the tabs.

  • Patent number: 4411341
    Abstract: Relative motion between movable parts is damped by way of a hydraulic damper having radial vanes in a hydraulic damping fluid filled working chamber and dividing the chamber into subchambers which respectively increase and decrease in volume in response to torsional movements of the vanes in the working chamber during relative rotation of subassemblies of the damper. Damping is effected by controlled displacement of the hydraulic damping fluid between the subchambers through restricted orifices across an edge of the vanes during torsional movements of the vanes responsive to relative motion of the parts to be damped. Damping may be provided in either direction of rotation. Another level or no damping may be provided in the opposite direction of rotation. Substantially equal damping may be effected in both directions of rotation. A range of adjustments of the restricted orifices is provided for.

  • Patent number: 4386728
    Abstract: A method of hermetically sealing by NVFE (non-vacuum focused energy) welding abutment joints formed by elongate surfaces. At substantially spaced intervals narrow shallow vent grooves are formed across one of the surfaces, while leaving between the vent grooves separating lengths of many times the length of the groove width. The grooves enable the NVFE welding to be effected continuously in unidirectional pass along the joint, the gases venting from the joint through the successive vent grooves as the welding progresses continuously along the joint. Continuously after the venting of the gases at each of the successive vent grooves, each vent groove is sealed by the NVFE welding without interrupting the welding progression.
