Abstract: The present disclosure is directed to an apparatus and method for forming sapphire ribbons via Edge-Defined Film-Fed Growth (EFG). Further, the present disclosure is directed to a plurality of concurrently grown sapphire ribbons having features such as a low dimensional variability and elimination of voiding between the sapphire ribbons concurrently grown in a batch.

Abstract: A synthetic bristle including a substantially continuous phase of polymer with spaced-apart microparticles in the interior thereof, at least some of said microparticles being close to the surface thereof for creating rough and irregular surface regions. The bristle can include a blowing agent in it, in addition to the microparticles, and the microparticles preferably are hollow glass beads. Brushes employing at least 5% by weight of the bristles of this invention also constitute a part of this invention, with the preferred brushes being applicator brushes, such as paintbrushes.

Abstract: The present invention provides for a method and articles produced from this method for eutectically bonding together single crystal elements, such as sapphire, to form a strong bond therebetween which can withstand high temperatures and chemical attack. The eutectic bonding mixture of the present invention can include a Group IIIA compound, such as yttria.

Abstract: A safety system for use with boats to be stored in enclosed buildings to minimize potential problems of fires and explosions. This system has a transmitting unit for attachment to the boat itself which is energized when the electrical distribution system of the boat is energized. This transmnitting unit generates a signal indicating this energized state. A receiving unit associated with the building receives any output signal of the transmitting unit and sounds an alarm when this output signal is detected by the receiving unit. In the preferred form, the transmitting unit and the receiving unit utilize infra-red light as the generated and received signal. Also in the preferred embodiment, the detector unit has a plurality of detector elements arranged along the side and top edges of a doorway leading into the storage facility. As a result of this system it can be assured that no boat with an energized electrical distribution system is stored within the facility.

Abstract: A sheet feeder apparatus having a deformable separator belt and an indexable retard roller includes a device for setting the proper depth of penetration of the retard roller into the deformable belt in the form of a flat surface on the periphery of the roller. In use, a deformable separator belt is placed in the sheet feeder over the flat surface of and adjacent to the retard roller. The proer penetration depth of the retard roller into the deformable belt is subsequently set by indexing the retard roller to present a non-flat surface adjacent the deformable belt.
