Abstract: A heat-resistant, protective glove having a shell made of a fabric of a temperature-resistant aromatic polyamide fiber, the outer surface of the shell being coated with a fire-resistant elastomer and a liner, generally conforming and secured to the shell and disposed inwardly of the shell, the liner being made of a felt fabric of a temperature-resistant aromatic polyamide fiber.

Abstract: An implantable drug deliver depot comprising a hydrophilic poly(glutamic acid-co-ethyl glutamate) structure having one or more substances, e.g., drugs and/or diagnostic agents physically contained therein. The drug or diagnostic agent is released by its permeation of and diffusion through the copolymer structure. The depot may be designed to release the substance or substances at predetermined rates and in predetermined sequence. The copolymer structure ultimately biodegrades to glutamic acid. Among the preferred configurations for the depots are rods and closed-end capsules.

Abstract: A heat-resistant protective glove having first and second shells which generally define the palm side and backside of the glove, respectively, each of the shell sections being made of a temperature-resistant aromatic polyamide fiber, the first shell section being a twill weave, the second shell section being a knitted fabric, a first liner section having a flame-resistant, elastomeric coating on a surface contiguous the inner surface of the first shell section, and a second liner section inwardly of the second shell section, the first and second liner sections generally conforming to the configuration of the first and second shell sections, respectively, both of the first and second liner sections being comprised of a felt fabric of a temperature-resistant aromatic polyamide fiber.

Abstract: Flame retardant, abrasion resistant elastomeric compositions comprised of thermoplastic polyurethane polymer and flame retarding amounts of a filler selected from decabromodiphenyloxide and antimony oxide in a 3:1 weight ratio, and decabromodiphenyloxide, antimony oxide, and ammonium polyphosphate in a 3:1:3 weight ratio respectively. Also, flame retardant, abrasion resistant, and heat sealable coated fabrics employing such elastomeric compositions as coating film.

Abstract: An implantable drug delivery device comprising a matrix formed of a poly-.alpha.-amino acid component having one or more drugs and/or diagnostic agents physically contained therein. The drug or diagnostic agent is released through one or both of two mechanisms: diffusion and biodegration which results from the action of enzymes, present in the host in which the implant is placed, on the polymeric matrix material. The implant device may be designed to release the drug or drugs at predetermined rates and in predetermined sequence. One preferred configuration for the implant device is a rod which may be inserted with a trocar.
