Abstract: ABSTRACT OF THE DISCLOSURE          A drainable blade louver comprises a pair of spaced-apart vertical members supporting a multiplicity of elongated, horizontally extending, inclined blades, each of which is of uniform cross section along its length.          Each blade has an upwardly open front drainage trough located adjacent the front edge of the blade and at least one second upwardly open drainage trough located in at least about the front one-third of the blade closely adjacent the front trough.  Each of the troughs is defined by spaced-apart front and back walls, the upper edges of which are preferably located in a plane substantially parallel to the airflow streams passing between the blades, and a bottom wall spaced a substantial distance below the upper edges of the front and back walls such that the splash from water drops impinging on the bottom walls of the troughs is largely confined to the zone bounded by the walls of the troughs thereby minimizing entrainment of water in the airflow streams.

Abstract: MULTI-ACTUATOR SYSTEM USING SINGLE MAGNETIC CIRCUIT Abstract A voice coil motor having a plurality of independent coils movable within annular flux gaps which are supplied in parallel with flux from a single permanent magnet.  The actuator comprises a single permanent magnet mounted to a low reluctance backing plate, a plurality of pole pieces, and a low reluctance casing including an integral pole plate provided with a like plurality of pole piece receiving apertures.  The casing extends from the perimeter of the pole plate portion to the backing plate completely surrounding the pole pieces, coils and the magnet.     Each pole piece has a rectangular base attached to the permanent magnet and a cylindrical portion which extends into the pole plate portion to define the annular gap, the axis of which is generally normal to the permanent magnet.  Adjacent pole pieces abut each other along one edge to assist in maintaining a balanced magnetomotive force to the pole pieces.  The axial length of the coil is less than the axial length of the annular air gap to provide a short coil long gap type of actuator and thereby minimize any interaction between the separate parallel flux paths which extend from the permanent magnet.

Abstract: Abstract of Disclosure An ureteral catheter stent comprises an elongated, flex-ible tubular member of uniform outside diameter throughout its length which has proximal and distal ends which are in the form of hooks.  Openings extend through the wall of the member to provide passages for fluid to enter the lumen of the tubular member and the proximal end of the member is closed to facilitate its introduction into a body passage.  Since the stent is straight-ened for introduction into a body passage by inserting a wire stylet in the lumen of the stent, the stent is provided with indicating means which show the direction the proximal hook will form when the stylet is removed so that proper placement is insured.

Abstract: Abstract of the Disclosure An electric spark building-up of metal on the working surface of rolls is effected by applying a voltage from a unipolar current source to each roll being treated and to an electrode interacting with the surface of the rolls.  Building up metal on the working surface of rollers is effected in the course of normal rolling operation, with the rate of the building-up of metal ex-ceeding the rate of wear of the roll surface so that a limit layer of metal is formed the thickness of which being maintained con-stant, thereby retaining the initial shape of the roll working surface.  The device for electric spark treatment is mounted on the rolling stand so that sliding contacts and electrodes are in contact with the rolls, the electrodes interacting with the surface of the rolls.  The proposed method for an electric spark treatment of rolls and the device for carrying out the method enable the initial shape of the roll working profile to be main-tained during the whole operating time, thus saving the metal being rolled, improving quality of the finished product and re-ducing costs of the rolls.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method and apparatus for carrying the method are disclosed which provide for selection by the user of a surface used as a reference in the detection of an intrusion. This is achieved by periodically projecting pulses of acoustical energy from a source towards a reference surface and detecting the reflection of such pulses of acoustical energy at a receiver and providing a first indication or signal representative of the reflected pulses.  A second indication or signal is generated which is adjustable and representative of the time elapsed between the projection of a pulse of acoustical energy from the source and the reception at the receiver of the pulse of acoustical energy when reflected from the selected reference surface.  The variations between the first and second indications are detected and compared and an alarm is generated when a variation is detected in the indications.  In the embodiment disclosed, the absence of variations between the first and second indications is measured by the coincidence of the first and second indications.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a process of pro-ducing vinyl polymers by an inversion polymerization technique in the presence of a coating on the internal surfaces of the polymerization reactor.  The coating on said surfaces may be a singular layer or a dual layer coating.  By inversion polymerization is meant conduct-ing the initial stage of the polymerization reaction in a medium wherein the monomer or monomers being polymer-ized constitute the continuous phase and in the second or later stage of polymerization, water constitutes the continuous phase.  The principal coating, or under-coating when a dual layer coating is employed, comprises protein, such as egg albumen, and when a top coating is used it comprises a water-soluble suspending agent, such as an alkyl or alkyl hydroxyalkyl cellulose ether. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C< grouping, and mixtures thereof, in the presence of said coating, polymer buildup on the inner surfaces of the reaction vessel is substantially eliminated.  With the present invention, multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges, thus preventing the escape of unreacted monomer to the atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE        A capacitive pressure sensor utilizing a sensing diaphragm and having a capacitor plate mounted directly to the diaphragm and movable therewith.  The plate and the diaphragm together form a capacitive sensor, and as the diaphragm deflects the capacitance between the plate and the diaphragm changes to provide a measure of the amount of deflection of the deaphragm.  The direct mounting of the capacitor plate to the diaphragm avoids many problems which might otherwise occur due to thermal transients and mechanical instabilities in the housing for the sensor.  In addition, a greater capacitance change is achieved for a given amount of deflection of the diaphragm.
