Granted: 1990-09-11
Abstract: TITLE A METHOD OF MANUFACTURING DISCRETE FIBER REINFORCED, PLASTIC TUBE AND APPARATUS THEREFOR ABSTRACT OF THE DISCLOSURE A method and an apparatus for making multi-layered plastic tube reinforced with fibers by a co-extrusion process. The method and appar-atus provide more specifically a multi-layered plastic tube with an intermediate layer thereof having discrete fibers where at least a major portion of the fibers is oriented to extend predominantly in a general direction lying between the circumferential and the longitudinal axis of the tube with the orientation of the fibers being generally the same throughout the thickness of the intermediate layer. In one embodiment, the method comprises (a) introducing a first plastic materiel in an up-stream portion of an annular die channel; (b) introducing a second plas-tic material filled with fibers in the upstream portion and around the whole of the first material; (c) introducing a third plastic material in the upstream portion and around the whole of the second material; and co-extruding the materials through a downstream portion of the annular die channel which is divergent diametrically in the downstream direction.

Abstract: SAFETY LATCH MECHANISM FOR CLOSURE        OF A PRESSURE VESSEL                   ABSTRACT OF THE DISCLOSURE         A safety latch mechanism for use in connection with a pressure vessel of the type having a shell, a closure for removably closing an access opening defined by the shell and a locking ring rotatably supported by the shell adjacent the access opening for releasably locking the closure in access opening closed position.  The mechanism features a first latch member mounted by the shell for releasably preventing unlocking rotation of the locking ring relative to the shell and a second latch member mounted by the locking ring and responsive to movement of the first member for releasably preventing relative rotational movements of the locking ring and closure.  The first member is operatively associated with a vessel exhaust valve, which tends to constrain unlatching movements of the first and second latch members, when the pressure within the vessel exceeds a safe level at which the closure may be operated without the possibility of injury to person or property.

Title: Vapor pressure measurement apparatus and method
Inventor: REED DONALD B
IPC: G01N7/14
Filed: 1987-10-28
Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE         Vapor pressure of liquid compositions is measured by a system having a cylinder member in which a reciprocal piston is disposed for movement to contain a sample of liquid and expand the chamber while measuring  the pressure in the chamber until a substantially constant pressure  is reached with increasing chamber volume.  Liquid is circulated from a source such as a petroleum pipeline to the apparatus and continually through the expansible chamber in a retracted position of the piston.  When a sample vapor pressure measurement is to be taken, the piston closes off a passage leading to the chamber and displaces liquid out of the chamber until a minimum volume is reached.  The movement of the piston is then reversed to increase  chamber volume  while  monitoring  pressure  and temperature to detect the onset of cavitation.   Different samples of the same liquid may be taken while permitting the maximum volume of the chamber to vary with each sample so that a plot of maximum or equilibrium pressures can be obtained as a function of chamber size whereby extrapolation may be used to determine true vapor pressure of the composition.

CRAWFORD                           ABSTRACT         Waistband interlinings are made by ultrasonically cutting a fabric having warp yarns and fill yarns of a thermoplastics material along lines parallel to the warp threads.  An acrylic finish on the fabric permits it to undergo the ultrasonic cutting, will retard the development of brittleness in the fused fibres, and keep the resulting fused edge intact.  The fabric should have at least 30 fill yarns per inch but no more than 42 warp yarns per inch.  The fabric is cut by passing it between a stationary pressing element, or knife, and the horn of an ultrasonic generator. The fill yarns melt as they pass between the knife and the horn and fuse into adjacent fill threads to form a con-tinuous edge along the length of the cut fabric.  The re-sulting waistband material has a smooth edge formed from fill, or weft, fibres fused to each other and to not more than one warp thread.  The waistband interlining finds use in a waistband assembly for slacks and pants.
