  • Patent number: 11602226
    Abstract: A pillow system includes a pillow assembly and a pillow and pillow cover assembly, the pillow assembly having a base attached to a pillow having an opening, the pillow formed of a first foam material, and the base formed of a second foam material, and wherein the first foam material is more rigid than the second foam material. The pillow and pillow cover assembly includes a pillow cover formed of a stretchy fabric material capable of stretching into the opening of the pillow during use.

  • Patent number: 5064935
    Abstract: Economic and efficient process for preparing an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) from a transesterification reaction mass by using a countercurrent column reactor system wherein the transesterification reaction mass is fed into the countercurrent column reactor and continuously flows downward while simultaneously a heated inert gas stream continuously flows upward to scrub out volatiles from the transesterification reaction mass, thereby yielding from the bottom of the countercurrent column reactor an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) suitable for use in a polycondensation reaction. Butanediol is recycled throughout the process through an absorber column.

  • Patent number: 4990335
    Abstract: Method of making tablets for active ingredient delivery by compressing a mixture of active ingredient and granular, high viscosity, fully hydrolyzed polyvinyl alcohol or copolymer of vinyl alcohol with methyl acrylate or methyl methacrylate. By use of a crystalline, heat treated polymer, a tablet providing quick active ingredient release is obtained. By using an amorphous, non-heat treated polymer a tablet providing prolonged active ingredient release is obtained. By using blends of crystalline and amorphous polymers, tablets having a range of active ingredient release characteristics can be obtained. The granular, high viscosity, fully hydrolyzed polymers provide flowability, compressibility and processing versatility advantages over conventional tablet binders.

  • Patent number: 4605800
    Abstract: An improved process for the catalytic dehydrochlorination of 3,4-dichlorobutene-1 with aqueous alkali, wherein the effluent from the dehydrochlorination reactor is separated into phases, and the organic phase is steam-stripped at low temperature (below about 80.degree. C.) to recover chloroprene product, while the steam stripper heels are returned to the dehydrochlorination reactor. A small portion of the heels are purged prior to being recycled. Most of the catalyst is recovered and returned to the reaction, but a small amount of make-up catalyst is added. Chloroprene made in this process is a valuable monomer which finds use in the manufacture of a broad line of synthetic elastomers of considerable industrial interest.

  • Patent number: 4335238
    Abstract: Terpolymer consisting of 12 to 48% by weight TFE units, 7 to 24% by weight HFP units and 30 to 81% by weight VF.sub.2 units, provided that when the content of TFE units is less than 42% by weight, the content of HFP units is less than 15% by weight. Heat-stable films such as polyimide film can be coated with a coating comprising the terpolymer to provide heat-sealable film useful as wire insulation.
