Abstract: Docket 6369 HIGH TURBULENCE SLOTTED CIRCULAR SCREEN                WITH COLUMN-SPACED ROTATING CLEANERS     Abstract of the Disclosure A method and apparatus for treating a suspension of liquid, paper making fibers and undesirable rejects to remove a substantial portion of the rejects from the suspen-sion.  A cylindrical screen is utilized which has narrow slots on the order of 0.001 to 0.008 inch in width disposed normally with respect to the screen axis, and bars projec-ting from the inlet face of the screen and cooperating with rotating foils for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen.          This permits the paper making fibers to pass through the narrow screen openings but causes very small reject particles, which would pass through the larger openings of conventional paper making screens, to be removed without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and rejects.

The second member is flat and rectangular shaped and has three vertically spaced apertures which mate to receive the three prongs therethrough.  The prongs of each first member are inserted through the upper three holes along one side of the computer paper, and the second member is then located on the prongs.  This is repeated on the other side with the other assembly to hold the sheets of paper in a single bundle.  The bundle is then located in the filing drawer and the outwardly projecting hook portions engage horizontal support bars to suspend the sheets of paper in the storage space.  Sheets of paper may be added to or taken from any bundle in the drawer merely by easily manually removing the second member from each assembly and then replacing them after the sheets have been added or taken away.  This system is very easy to use and extremely inexpensive to manufacture and the com-ponents are standard and interchangeable.  In one embodiment, additional second members may be used to add more sheets to any bundle without separating the original members.

Abstract: ABSTRACT OF THE DISCLOSURE            CONNECTION MECHANISM FOR AUTOMATIC SLACK ADJUSTER An automatic slack adjuster for a vehicle braking system includes a yoke assembly which is pivotally mounted on the adjuster body and in which is adapted to be connected to a push rod actuated by a fluid pressure actuator.  The yoke assembly includes a recess having an entrance which is adapted to receive the end of the push rod.  An adapter member is threaded on the end of the push rod received in the recess, and a U-shaped connector penetrates the body of the yoke to engage a circumferentially extending groove on the adapter, to thereby define a nonthrust transmitting connection between the yoke and the push rod.  The yoke assembly defines a pair of thrust receiving surfaces which circumscribe the entrance to the recess, and a thrust washer slidable on the push rod is held at a thrust transmitting engagement with one of the thrust receiving surfaces by a nut which Is threaded on the end of the push rod.  The adapter is stepped to define larger and smaller surfaces with a shoulder therebetween which is adapted to engage the other thrust transmitting surface.  Consequently, braking thrust is exerted on the yoke assembly through the push rod, the thrust washer, and the one thrust receiving surface, but if the thrust washer Is moved out of thrust-transmitting engagement with the one surface, thrust may be transmitted to the other surface through the shoulder.

Abstract: TITLE    LUMINAIRE APPARATUS WITH MULTIPLE LIGHT SOURCES           AND METHODS OF OPERATING SAME                         ABSTRACT           A luminaire housing body is formed with a reflector chamber closed at one side by a radiation transmitting member. At an opposite side, the housing is extended to form a socket enclosure.  A lamp socket member is rotatably mounted in the socket enclosure and is structured to define spaced apart inwardly dished reflector surfaces, hereinafter referred to as  concaved  reflective   surfaces, in each of which a lamp may be placed at a focal point and independently energized by electrical means.  A reflector member is located in back of the radiation transmitting member and is formed with a socket aperture.         At either side of the concaved reflector surfaces, the socket member is shaped to present tapered outer ends which can be moved into and out of the socket aperture.  The arrangement of the parts is such that a de-energized lamp is constantly shielded by the tapered ends to prevent shadow or distortion when another lamp is in use. The socket member is rotated by means of a socket locking spindle which when removed, allows for lamp socket replacement. if desired.         When the luminaire apparatus is utilized as a portable unit, the lamps are energized by a battery also carried by the user.  Each lamp is independently operable by switch control means in the socket enclosure.  When provided with an attaching hook, the housing in a relatively small size may he attached to a cap member to constitute a head-piece.  Such a headpiece is particularly suited for use with a miner's can lamp apparatus wherein the rotary socket means may support dual lamps to provide a miner with effective back-up light sources.

Abstract: IMPROVED FLOW CONTROL DEVICE     Abstract of the Disclosure An improved flow control device for regulating the flow of fluid through flexible tubing wherein the flow control device utilizes a rotatable member with trunions positioned to be captively guided and rotated along guide surfaces.  The rotatable member is easily inserted into the clamp body yet once it is placed therein it is dif-ficult to remove without excessive force.  The clamp body affords a rigid structure with the opposing walls being fixed at their ends yet are flexible enough to afford entry of the rotatable member into the clamp body for placement of the trunions in the guide surfaces.  In one embodiment, a ramp means is provided through an infeed section wherein the ridge portions forming the ramp merge with the guide surfaces so that when the trunions of the roller move up the ramp and onto the guide surfaces, an outward flexing of the clamp wall is effected with a re-tention of the trunions on the guide surfaces.  In another embodiment, the walls defining an open slot at the top of the clamp body are weakened such as by beveling so as to permit the trunions of the roller to enter into the clamp cavity and be retained on the guide means.
