  • Patent number: 4709485
    Abstract: A cylindrical alignment housing is fixed to a housing of one of two axially aligned items of equipment. A cylindrical bearing housing is concentrically positioned around the cylindrical alignment housing, such that the cylindrical bearing housing is rotatably supported at a given position on the cylindrical alignment housing, which is fixed to the housing of the aforesaid one item of equipment. A mechanical coupling is provided between the bearing housing and the shaft of the other of the two equipment items that the bearing housing and the shaft will rotate in concert. A laser is positioned on the rotatable bearing housing and a prism is positioned on the other of the two items of equipment. The cylindrical bearing housing and the shaft of the aforesaid other equipment item are rotated together in concert, and measurements are taken using the laser and prism to determine whether the shafts are properly aligned with each other.

  • Patent number: 3981222
    Abstract: 1. A method of making a time delay fuse comprising the steps of overlaying a fuse strip consisting essentially of a paper formed of non-combustible insulating fibers filled with a combustible compositon which evolves substantially no gas on burning with a backing strip wider than said fuse strip consisting essentially of a paper formed from non-combustible insulating fibers, both ends of said fuse strip extending beyond and normal to said backing strip, winding said overlaid fuse strip in a flat spiral around the circumference of a cylindrical core formed from non-combustible insulating fibers to form a cylindrical body having said both fuse strip ends exposed on the surface of said core while maintaining a high water content in said fuse strip, backing strip and core, axially compressing said body to form a compact, and drying said compact.
