Abstract: METHOD AND APPARATUS FOR DETERMINING COAGULATION TIMES         Abstract of Disclosure A method and apparatus for determining coagulation times in such clinical laboratory procedures as prothrombin time tests, activated partial thromboplastin time tests, fibrinogen determinations, factor assays for specific blood coagulation factors, and the like.  A fibrous filament is drawn at a predetermined rate through a small body of liquid to be tested and the interval, from the time a suitable coagulating agent is mixed with the liquid to the time the body of liquid clings to the filament and moves with it, is precisely measured as a direct indication of actual coagulation time.  The liquid body is supported upon a non-wettable inclined surface bordered by walls defining a well for receiving the liquid and a pathway for its movement.          Particularly effective results are achieved by utilizing a pair of spaced filaments moving at precisely the same rate, the filaments being bridged by a web or mass of clotted liquid when coagulation occurs.  A photodetector senses movement of the clot and a timer automatically measures the time between coagulant addition and clot formation.  After clot detection occurs, an arm lifts the paired filaments from the well while at the same time directing the advancing filaments through slots to strip coagulum therefrom, then lifts the filaments out of the slots to permit fresh filament sections to move into place, and finally lowers the fresh sections onto a clean inclined surface for another coagulation test.  Means are also disclosed for gently agitating the coagulating agent or agents prior to admixture with the test liquid, for insuring proper suspension of the reactants, and for reducing risks of infection and cross contamination during use of the apparatus.

Abstract: TITLE          Electrical Power Switch With Pressurized Gas Blasting Device For Lengthenng The Switching Arc ABSTRACT           An electrical power switch operating with a pressurized gas for actuating the switch contacts and also providing a quenching action in which the arc is lengthened and extinguished includes a container in which the pressurized gas is stored, the outlet from this container being located adjacent the junction area between a plurality of contact fingers in fixed position and a movable contact member that also includes a valve member for closing off the gas outlet from the container when the switch contacts are closed.  When the movable contact is released for initiating an opening operation of the contacts, the pressure of the gas stored in the container forces the valve open thus releasing the gas for blasting the arc drawn between the contacts.          The gas enters an annular chamber surrounding the junction line of the contacts which includes two half-turn helical travel rails of different radius and opposite winding sense to which the feet of the arc are transferred from the contacts and travel downward and into a group of circumferentially spaced nozzles in which the arc is further lengthened.

Abstract: ABSTRACT OF THE DISCLOSURE:  The invention relates to polymeric coating compositions which are at least partially soluble in water.     Polyesterimides, polyesteramideimides, polyester-imidehydantions and polyesterimide urethanes are prepared which have enhanced solubility in water.  The reactants which form the various polymers are reacted to essentially a zero acid number with essentially no free carboxyl groups or those which are not part of the formed imide moiety or link-ages.  At least some of the imide rings are then cleaved or split with amine material to enhance solubility in water. The compositions are particularly useful as electrical insulating coatings or wire enamel and can also be used in preparing laminates and composites and for general coating purposes.

Abstract: DRILL GRINDING DEVICE            Abstract of the Disclosure A device for positioning, holding and feeding twist drills and the like to a grind stone to grind the bevels of the faces of the drill accurately and symmetrically is dis-closed.     A drill locking means has a bed for holding the drill and a fence to restrain it in one direction.  A finger which has means forming an inclined plane on one side and which comes to a point near the fence is carried by the bed.          The flute trailing edge of the drill engages the inclined plane at various points depending on the drill size.  The force of the grind stone rotates the flute trailing edge against the inclined plane.  There is also an adjustable drill stop to provide longitudinal drill positioning.  The combination of bed, fence, finger and drill stop locks the drill in place against the grind stone during the grinding operation.  To grind the opposite face, the drill is rotated approximately 180° and replaced.  The moving grind stone will urge the drill into exact 180° opposition in the drill lock-ing means, automatically.     The drill is fed in a straight line into the stone by means of nesting troughs.  The drill locking means in trough form with the drill in place can be removed for inspection or quenching of the drill and returned to the same position.     means for controlling the forward excursion of the drill is provided by a threaded screw carried by one of the troughs which bears against the other trough.  A tension bar tightens by rotation against the carrying trough to hold the screw in place.

Abstract: ABSTRACT OF THE DISCLOSURE           A four position racking mechanism for a circuit breaker in a cubicle or housing providing Connected, Test, Disconnect and Out positions.  The racking lead screw is mounted in the circuit breaker structure in its own support.          The rear end of the racking screw is threaded to engage and move a travelling nut which rides in guide slots.  The outer ends of the travelling nut engage a pair of connecting links which rotate a pivoted roller bracket.  The roller bracket carries a racking roller which engages a cam slot in a member extending from the rear portion of the cubicle or housing.          The shape of the cam slot plus the increasing lever arm of the connecting links around the pivot pin on the nut provide a variable racking force which is needed for primary disconnect contact engagement.  The central positioning of the racking mechanism makes it suitable for any width of circuit breaker.          The racking mechanism is interlocked with the closing mechanism; releasable locking means and interlock means are provided to limit the operation of the racking mechanism to conditions which are safe for the operator; thus, the unlocking of the racking mechanism after the breaker is tripped will hold the trip mechanism and hold it trip free as long as the racking mechanism is unlocked.  An indexing element for the slide for the locking mechanism is provided for all the positions of the circuit breaker.
