  • Patent number: 4430075
    Abstract: An improved dosing tip having a tapered portion for application to the mouth of a host for administering a dose of medicament, food, vitamins, or the like, including gripping means on the tapered portion for being firmly engaged by the teeth, lips, gums, or jaws of the host and for readily releasing said tapered portion upon terminating the administration of the dose to the host.

  • Patent number: 4414756
    Abstract: An improved method and apparatus for treating strand-like material is described. The method comprises conveying loops of such strand-like material supported by conveyor means through a heating zone wherein provision is made for causing certain portions of said loop material to experience substantial peripheral sliding movement in their contact with and with respect to said conveyor means, which movement has been found to reduce irregularities in the subsequent dyeing of the strand-like material.

  • Patent number: 4060354
    Abstract: An energy saving and material conserving apparatus is 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 an 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.

  • Patent number: 4017245
    Abstract: Method and apparatus for extruding expandable thermoplastic material having a cellular internal body portion and formed thereon a substantially non-cellular high density skin. The extruded material is contacted by a pair of continuously traveling temperature controlled belts immediately upon leaving the extrusion die which serve to form the high density skin thereon and the spacing of the belts is selectively controlled downstream from the extrusion die with the use of selectively adjustable belt backing members. Selectively controlling the spacing of the belts while the extruded material is undergoing expansion or foaming results in a predetermined internal cellular structure of said extruded material especially with regard to the size and distribution of the cells across a cross-section of the material.

  • Patent number: 4000810
    Abstract: A protective case for clip-on sunglasses (clip-ons) including a rigid plastic pouched shaped body having means thereon for preventing damage to the lenses or clip structure of the clip-ons and for maintaining the clip-ons properly positioned in the case to prevent inadvertent slippage or removal thereof.

  • Patent number: 3963816
    Abstract: Molded articles are made from expandable thermoplastic resin material by pre-expanding the thermoplastic material in particulate or bead form containing as the principal expanding agent a liquid hydrocarbon by contact with steam until the desired degree of expansion is obtained, heating the beads in a stream of substantially dry, hot gas at a temperature above the boiling point of the hydrocarbon but below the fusion temperatures of the thermoplastic material while agitating the beads to prevent agglomeration upon softening until substantially all of the moisture is removed from the surfaces of the pre-expanded beads, and molding the article from the heated pre-expanded beads by placing them in a closed mold and heating them to a temperature above their fusion temperature, the temperature of the thermoplastic material being continuously maintained above the boiling point of the expanding agent from the time the beads are pre-expanded until they are molded into the shaped article.
