Abstract: ABSTRACT OF THE INVENTION           An endoscopic instrument (endoscope or specu-lum) is provided with a chemiluminescent light source for inspection and examination of body cavities.  The light source comprises a body containing at least two compartments separated by a barrier, each compartment filled with a suitable fluorescing component, such that by breaking the barrier between the compartments and causing admixing of the components, a chemical reaction occurs, which produces the chemiluminescent effect.         A vaginal speculum is provided having coopera-ting upper and lower dilator blades pivoted with respect to one another, a means associated with at least one dllator blade for releasably engaging thereto a chemilu-minescent light source adapted to direct its light in-termediate the dilator blades in their extended position to illuminate the body cavity being examined.  Also provided is a medical examination light able to be removably secured to a speculum of the type having a body and a plurality of dilator members extending there-from,  the light comprising a light transmitting member attached to an open-ended elastomeric sleeve member of sufficient size to encircle the extending portion of a dilator blade, receiving and retaining it in a removable tight friction fit thereon.

Abstract: IMPROVED TOROIDAL TRANSFORMER AND MACHINES                AND METHODS FOR MAKING SAME                  ABSTRACT OF THE DISCLOSURE           An apparatus for making a toroidal transformer by unreeling a strip of a core material from the inside of a coil of the core material and by winding the strip of the core material into prewound primary and secondary windings of the transformer.  The apparatus has a turntable for rotating the coil about its axis in a direction to con-tinually unwind the strip of core material from the inside of the coil.  There is a directing device for receiving the strip of material from the inside of the coil and for directing the strip of material away from the coil.  A retarding force can be applied to the strip of material to push the strip against the inside of the coil to minimize bending of the strip as it separates from the inside of the coil during unwinding.  The strip can be wound from said directing means into said prewound primary and secondary windings.

Granted: 1993-05-11
Abstract: ABSTRACT           A method is disclosed for making abrasive articles having abrasive particles embedded in elecrodeposits of metal provided at a multitude of discrete locations on a backing fabric.  The backing fabric is first coated with a vaporized metal such that the vaporized metal becomes firmly attached to the fabric to provide a conductive coating.  The coating is masked at the discrete locations.  Then metal is deposited elctrolytically at the discrete locations in the presence of the abrasive particles so that the abrasive particles become embedded in the metal.  The method permits the manufacture of an abrasive strip that is ready for use, without the need to bond it unto a backing material.

Title: Coater and method of operating such coater
Inventor: ALHEID ROBERT J
IPC: B05C9/10
Filed: 1987-11-27
Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE      A coater and a method of operating such coater is disclosed.  The method of operating the coater includes the steps of separating a first tail from a full width web unwound from an unwind stand at threading velocity and threading the first tail at the threading velocity through a pull stack.  The first tail is widened to the full width of the web so that a full width web extends through the pull stack.  The full width web emerging from the pull stack is dumped into a first broke chute which is disposed below the pull stack.   The full width web extending through the pull stack is accelerated along with a coating apparatus to coating velocity so that both the full width web and the coating apparatus attain coating velocity.  A second tail is cut in the full width web between the unwind stand and the pull stack and such second tail is threaded through the coating apparatus while the second tail is moving at coating velocity.  Meanwhile, the full width web less the second tail continues to be disposed to the first broke chute.  The second tail is widened to full width so that a full width web extends through the coating apparatus and the full width web is then coated during passage through the coating apparatus.   Finally,  the coated web is reeled into a windup reel.
