  • Patent number: 3946298
    Abstract: A rotatable shaft positioning mechanism is disclosed for use with a multiple spindle automatic machine tool having a plurality of rotatable spindles in an indexable spindle carrier. A Hall effect sensor is actuated by a permanent magnet rotating with each spindle to develop a reference signal which starts a counter counting pulse generated by a pulse generator connected to the output of a stepping motor. The stepping motor is connected to rotate the spindle and when the counter counts out, the spindle is stopped at the preset position. The spindle is held in place and the machine tool may be operated for performing a machining function on a workpiece held in the spindle, for example, a cross drilling attachment, cross-tapping attachment or alternatively, the spindle may be rotated at a slow speed by the stepping motor to perform a contouring or assembling operation on a workpiece in the spindle.

  • Patent number: 3944116
    Abstract: The present invention discloses a process of closing a nozzle hole in the bottom of a tundish, which is used in pouring molten steel. The tundish has a bottom, which is generally funnel-shaped and, also, has wall means which define the nozzle hole. The steps of the process comprise placing a closure in the nozzle hole to close the same and then placing a finely divided chrome compound on top of the closure and into the nozzle hole and in an amount to at least partially fill the bottom of the tundish. The chrome compound has a sintering temperature of on the order of at least 1740.degree. C. The closure is provided by inserting a rolled up and pressed asbestos bead into the nozzle hole with an end of the bead extending out of the nozzle hole in a position to be grasped by a workman. The tundish of the present invention is operated by pouring molten steel into the tundish and on top of the finely divided chrome compound, which resides on top of the closure.

  • Patent number: 3938729
    Abstract: A carrying tray is provided incorporating a top member of single face corrugated paper board which is bonded to a bottom member made of a single paper board. The bottom member extends beyond the top member and forms a substantially triangular beam bounding the perimeter of the top member to provide a rim for improving the stability and strength of the tray. A tab extending from one of the beams is adhesively bonded to an adjacent beam to provide strength at a corner of the tray. The tray can be economically and readily decorated using commercial printing systems such as flexographic gravure and silk screening.

  • Patent number: 3936724
    Abstract: This invention is directed to an automatic voltage regulator for a seperately excited generator comprising a main AC generator including an armature winding and an exciting winding and an exciter of an AC magneto generator associated with the exciting winding of the main AC generator. The regulator comprises a single controlled semiconductor switching device disposed in parallel to the exciting winding of the main AC generator and an output voltage detecting and control signal generating circuit which is adapted to detect the output voltage of the main AC generator and to apply a control signal to the controlled electrode of the controlled semiconductor switching device when the output voltage of the main AC generator reaches more than a predetermined value. The exciter of the AC magneto generator has an operating frequency higher than that of the main AC generator whereby the output voltage of the main generator can be regulated in a minute manner.

  • Patent number: 3932724
    Abstract: A capacitance discharge stud welding apparatus which comprises a housing. A coil is positioned in the housing and an armature is located within the coil and is movable between first and second positions relative to the coil. A stud chuck is provided for the purpose of holding a stud and is connected to the armature for movement therewith. A relatively light spring constantly urges the armature and the stud chuck toward the first position of the armature in the direction of a metal member to which a stud held by the chuck is to be welded. Engagement of the stud held by the chuck with a metal member causes the armature to move to the second position relative to the coil and against the urging of the light spring. An electrical welding current circuit is provided and electrical connection means connect the welding current circuit to the chuck and to a stud held thereby.

  • Patent number: 3930298
    Abstract: The method of forming a tube fitting assembly is disclosed in a fitting having a first bore through a portion of the fitting and a second bore larger than the first bore and concentric with and through a portion of the first bore. A tubing having a diameter substantially equal to the first bore is engaged against an inside surface of the fitting defined by the end of the first bore. Relative movement between the fitting and the tube deforms the tubing wall to engage the first and second bores and to form an annular bead of the tubing wall outside of the fitting assembly. The bead is swaged into engagement with an outside surface of the fitting surrounding the second bore. The foregoing is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
