Title: Method and apparatus for pre-expanding and molding  expandable thermoplastic polymer particles
Inventor: SMITH STUART B
Filed: 1977-06-17
Granted: 1980-07-29
Abstract: Abstract of the Disclosure An energy saving and material conserving method and apparatus are provided for expanding and molding expandable thermoplastic polymer particles.  Especially significant is the ability to produce molded objects of generally uniform density in the higher density range in the order of 4 - 15 pounds per square inch,or greater,as well as lower density molded objects due to improved control of the particle expansion.     The particles are partially expanded in a vessel in a heated substantially dry atmosphere and agitated in a manner to provide uniform heating thereof.  After a initial heating period to soften and partially expand the particles they are subjected to superatmospheric pressure to substantially prevent further expansion and are discharged and conveyed to a mold for further expansion therein.  In certain instances,the particles are subjected to superatmospheric pressure within the vessel during a portion of the initial heating period to prevent premature particles expansion and loss of blowing agent within the particles.  The temperature of the particles are continuously maintained above the boiling point of the blowing agent within said particles at all times subsequent to the partial expansion of the particles up to the final expansion and fusion of the particles in a mold.

Abstract: ABSTRACT OF THE DISCLOSURE       A nonwoven fabric having alternating stripes of high fiber density and low fiber density is made in such a manner that the high fiber density stripes run across the fabric and maximize the cross direction strength to a point that the cross direction/machine direction strength ratio approaches unity.  This advantageous and desirable characteristic can be achieved by hydroforming a card web, by disposing the carded web on a relatively fine mesh screen and placing a finger-like striping bars over the web with the axis of the bars at 90° to the card web's general fiber orientation.  Water was then sprayed over the assembly with sufficient force to rearrange the fibers in the web thereby producing the nonwoven fabric of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure is directed to a hand tool of the pliers configuration having a set of crimping nests located in jaw members.  In particular, one jaw may have two crimping nests, each nest having an expansion zone on each side thereof to receive any material flowing out from the nest when a terminal is crimped therein.  The expansion zones between the two crimping nests overlap so as to permit placement of each of the nests closer to the optimum distance from the handle pivot.  A visual indicator permits the operator to crimp terminals of different discrete sizes in a single one of the crimping nests and a hook member used to lock the handles in a closed position further provides discrete limits of crimping nest closure.  A compression spring located in overlapping slots of the handle member provides a recessed means to rapidly open the handles when the hook member is released.          Discretely sized insulation cutting edges located between the pivot and the handle free ends permits the edge to overlap one another and thus provide a complete cut about the wire periphery and provide a wedge to break through the uncut land of insulation.

Abstract: ABSTRACT OF THE DISCLOSURE A portable camera is described by which electrostatic photocopies can be obtained instead of conventional photographs.  The camera includes conventional aperture and optical focusing means for producing an image, a surface on which the image is formed, electrode means for electrically charging the surface, an integral EHT generator for producing a high voltage pulse for application to the electrode, a shutter for controlling the passage of light to the surface and a means for applying a printing medium to the surface for retention thereon in dependence on the level of electrical charge remaining at different points over the surface after exposure to the light image. Rollers and a reservoir of a suspension of printing medium particles serve to apply the printing medium to the surface and heated rollers or pressure rollers are used to fix the print. A development electrode may be employed in the form of a grounded con-ductive plate or roller placed in the immediate vicinity of the electrical image to eliminate edge effect. The surface on which the image is formed may comprise a zinc oxide coated paper or a plate coated with cadmium sulphide or selenium for producing an intermediate electrostatic image.  Where zinc oxide coated paper is employed, the optical system must produce an inverted real optical image. Distribution of charge is improved by incorporating a frame electrode at the same potential as the surface. A transparent dotted screen may be inserted in front of the surface prior to image exposure so as to produce a plurality of isolated areas of charge on the surface to reduce charge migration and maintain charge and print density levels. Uniformity of charge is compensated by an aperture in an opaque member which causes a fall-off in light intensity over the surface similar to the fall-off of charge intensity from the electrode.
