Abstract: METHOD AND APPARATUS FOR MEASURING            NEUTRON CHARACTERISTICS OF MATERIAL                  SURROUNDING A BOREHOLE          Abstract of the Disclosure A pulsed source of fast neutrons and a radiation detector system are utilized in a well logging instrument, the detector being responsive to the thermal neutron popu-lation decay rate.  The inverse of the decay rate is pro-portional to the measured macroscopic neutron absorption cross-section (Sigma).  A Sigma is calculated by taking the natural logarithm of the ratio of the detected radiation counts occurring within two measurement intervals of fixed duration and starting at a fixed time after the neutron burst.  This Sigma measurement provides a feedback voltage which is used in altering the starting time of a single measurement interval in a subsequent source pulsing cycle to provide a measured Sigma value.

Abstract: A FASTENER WITH A MODIFIED THREAD FORM     ABSTRACT     A threaded fastener with a modified thread form dis-courages a nut from becoming irremovably frozen on the shank of a bolt.  A first normal thread extends from a base reference surface to a height on the fastener shank to permit full thread engagement by a nut.  Axially outwardly along the shank from that point, there is provided a second thread of reduced crest diameter but still of sufficient size to engage the threads on the nut.  This reduction in thread diameter provides additional clearance to permit the nut to be backed off in spite of marred threads or paint or rust buildups.

Abstract: ABSTRACT OF THE DISCLOSURE A thermoplastic polycarbonate molding composition is provided which contains a particulate or a fibrous filler coated with a silane.  It has been found that when particulate fillers or fibrous fillers containing reactive groups are coated with a silane, the reactive groups are rendered inert to polycarbonate resins.  The silane-coated particulate or fibrous fillers can be readily employed with thermoplastic polycarbonate resins without degrading, corroding, or otherwise adversely affecting the resins. The particulate fillers have an advantage in that they are less expensive.  Alternatively, the particulate fillers and silane can be mixed with the polycarbonate resin to achieve the same result.

Abstract: SECURITY LATCH ASSEMBLY                  ABSTRACT OF THE DISCLOSURE         A security latch assembly for sliding closures is provided.          The security latch assembly includes a rod member which is swingably attached to the top track of the closures and has two basic positions, an up and a down position.  The rod member is an elongated rod that extends between the edge of a first of the closures and a side of the opening containing the closures across the width of a second of the closures and within the track of the first closure when the elongated rod is in the down position and the closures are closed.  The invention includes an end member which is attached to the end of the rod member which abuts the edge of the first closure when the closures are closed and when the rod member is in the down position.  When the rod member is in the down position, the end member lies in the plane of the second closure and thus prevents the second closure from sliding within its tracks.  Some embodiments of this invention include a latching assembly which is attached to the wall adjacent the closures a set distance from the closures.  These embodiments include an exten-sion member which is attached to the rod member and which extends between the rod member and the latching assembly.  The extension member is compatible with the latching assembly such that the latching assembly secures the rod member in the up and down posi-tions.  The latching assembly may be comprised of a pair of lock-ing pins which alternatively engage a hole in the end of the extension member to secure the rod member in its positions.  In certain embodiments of this invention, the invention includes a pair of metal grillwork doors which are employed in conjunction with the rod member and end plate.  The metal grillwork doors can be located adjacent to and parallel to sliding glass closures. In these embodiments, the rod member lies in the track of one of the metal doors and the end plate prevents the other metal door from being slid in its track. For added protection, a locking assembly can be added to one of the metal doors which attaches to the end member when the rod member is in the down position.

Abstract: SUBMERSIBLE PUMP CHECK VALVE     ABSTRACT OF THE DISCLOSURE         A valve element for reciprocation within a port has a body member which cooperates with a valve seat defined on a wall around the port.  A plurality of resilient legs extend from the body member through the port and terminate in feet which extend radially beyond the periphery of the port.  A central bore in the body member, parallel to the legs receives a locking stem which reciprocates between a locked position and an unlocked position. In the locked position, a locking disc on the stem engages projections extending radially inward from the legs to prevent the legs from moving inward, thereby locking the valve element within the port. In the unlocked position, the locking disc is out of alignment with the projections, and bevelled surfaces on the feet cooperate with the wall to cam the legs inwardly, so that the valve element can be removed from the port when it is subjected to sufficient axial force.  An annular ridge on the stem cooperates with a resilient flange spaced from the body member to releasably retain the stem in its locked and unlocked positions.  A pair of prongs extend from a portion of the stem ouside the bore beyond the periphery of the bore and engage the valve body to prevent the separation of the stem fr? the valve body.  A sealing ring is seated in a groove defined on a portion of the stem within the bore to prevent the flow of fluid between the stem and the body member.  The body member can be used without the stem as a flow responsive flow restricting element which permits full flow in one direction and restricted flow in the opposite direction.
