  • Patent number: 4774754
    Abstract: A dynamoelectric machine including a brush holder having a displaceable section for positioning the brushes in a mounting position is disclosed. The displaceable section is located to secure the brushes in a mounting position and said displaceable section being separated during assembly to allow the brushes to be displaced inwardly to engage the commutator in the final assembled position. Several embodiments of displaceable sections are disclosed.

  • Patent number: 4715623
    Abstract: A method of impressing a secret pattern on a substrate by the use of an uninked intaglio printing plate having the foreground area with a pattern of ridges and grooves which are distinctively different from the ridges and grooves in a background area enclosing the foreground area. The secret pattern may be observed only a person who is informed as to what pattern he is looking for and how to look at that pattern. Particularly, his line of sight must make a certain angle with the plane of the impressed substrate. The line of sight must also be oriented properly with respect to the background and foreground areas.

  • Patent number: 4712086
    Abstract: The invention relates to a support frame for a resistor element in a heating furnace for glass sheets, said flame providing a substantially continuously extending, elongated rest surface for a resistor element. The support frame elements consist of trough-like castings and are fastened to each other in an articulated manner. The short frame elements are easy to cast and can be assembled into long continuous support frames for resistor elements, the thermal stresses of said frames not passing over the link points. A long continuous support frame structure makes it accordingly possible to employ resistor elements that are long and continuous and thus readily replaceable.

  • Patent number: 4694559
    Abstract: The present invention relates to an expandable arbor which is removably attached to a standard decoiler mechanism. The expandable arbor has at least two opposed sections, each having an elongated transversely curved outer surface interconnected by a guide and track to the decoiler mechanism. The guide and track convert lateral movement of the decoiler mechanism into radial movement of the sections. The sections are laterally moveable into the axial bore of a coil of material and thereafter expanded by relative movement of the decoiler mechanism between the sections of the expandable arbor. An equalizer is provided to retract and coordinate movement of the sections.

  • Patent number: 4657167
    Abstract: An apparatus for feeding and positioning disks upon insulation or roofing membrane for attachment to a roof or deck by fasteners driven through the disks into the underlying layer. A support frame is provided with two wheels on only one side to avoid wrinkling a roofing membrane. A disk supply magazine supports a stack of disks. A separating and feeding structure supplies individual disks to an oblique chute which conveys them to a driving position which is laterally offset from the magazine. The disks are attracted by magnet into position upon a pair of resiliently bendable springs which are cantilevered from opposite edges of the bottom opening of the chute.
