Title: Induction plasma synthesis of nanopowders
Inventor: JUREWICZ JERZY
IPC: B01J2/04
Filed: 2006-01-27
Abstract: A process and apparatus for synthesizing a nanopowder is presented. In particular, a process for the synthesis of nanopowders of various materials such as metals, alloys, ceramics and composites by induction plasma technology, using organometallic compounds, chlorides, bromides, fluorides, iodides, nitrites, nitrates, oxalates and carbonates as precursors is disclosed. The process comprises feeding a reactant material into a plasma torch in which is generated a plasma flow having a temperature sufficiently high to yield a superheated vapour of the material; transporting said vapour by means of the plasma flow into a quenching zone; injecting a cold quench gas into the plasma flow in the quenching zone to form a renewable gaseous cold front; and forming a nanopowder at the interface between the renewable gaseous cold front and the plasma flow.

Abstract: Apparatus and methods of expanding a portion of a tubular are provided. The expansion apparatus includes a rotary expander for expanding an expandable tubular. A spline assembly is provided for coupling the rotary expander to a motor disposed on a work string. The spline assembly allows the rotary expander to be rotated by the motor and move axially relative to the motor. The rotary expander includes two rows of rollers for expansion against the tubular. The position of the rollers on the first row is skewed in one direction relative to the longitudinal axis. The rollers on the second row are skewed in an opposite direction. When actuated, the skew angle of the rollers will cause the expander tool to move axially. Alternating actuation between the two rows of rollers causes the expander to move in opposite axial directions during expansion.

Title: Child-resistant closure, package and method of making
Inventor: SHINGLE JOHN M
IPC: B65D41/36
Filed: 2006-07-14
Abstract: A closure includes a skirt (40) and internal lugs (42) on the skirt. The skirt has an undulating circumferential contour that includes alternate outwardly convex and outwardly concave portions (48, 50), with the internal lugs being disposed within the outwardly concave portions of the skirt. The skirt preferably is sufficiently flexible to allow the outwardly concave portions of the skirt to assume an outwardly convex geometry as a result of outward pressure on the internal lugs during demolding of the closure. The closure thus may be simply axially stripped from the mold core during the demolding operation without requiring movement of portions of the mold core to clear a path for travel of the lugs. The lugs preferably are shaped as an inverted U  that opens toward a free edge of the skirt, further to facilitate demolding of the closure.

Abstract: An object is to reduce the cost of a screw (20) and improve the quality of molded products. A rear end of the screw (20) is connected to a drive apparatus. The screw includes a screw head, a reverse-flow prevention apparatus, and a plasticizing member disposed rearward of the reverse-flow prevention apparatus. The plasticizing member includes a screw body (52), a flight (53) projectingly formed on an outer circumferential surface of the screw body (52), and a pressure member (54) formed to extend over a predetermined distance from the front end of the screw body (52) and to be located adjacent to the reverse-flow prevention apparatus.  The pressure member (54) has a flat outer circumferential surface. Since the pressure member (54) has a flat outer circumferential surface having a diameter equal to or greater than the diameter of the screw body (52), the shape of the screw (20) can be simplified, and the cost of the screw (20) can be lowered. In addition, the number of locations where a molding material stagnates can be reduced.
