Disclosed is a fire protection system including a plurality of suppressor modules, each having a plurality of extinguishing agent filled suppressor units, an activator associated with each of the units and activatable by electrical current flow to induce release of its extinguishing agent, a series circuit connecting the activators in series, and an initiator circuit for initiating electrical current flow to the activators. A detector responds to the presence of combustion products by activating the initiator circuits in a first plurality of the modules. Also responsive to activation of the initiator circuits in each of the first plurality of modules is a response relay that closes contacts to activate the initiator circuits in another plurality of modules. This in turn energizes additional response relays to close contacts that activate the initiator circuits in an additional plurality of the modules. Sequential activation of the suppressor units in individual modules continues in this manner until all suppressor units in all modules of the system have been activated.

Sheet materials for cardiovascular and other prosthetic implants are fabricated of synthetic elastomers. These materials are characterized by molecular configurations that produce a nonlinear tensile modulus characteristic similar in shape to that of natural tissue. Selected elastomers, when formed as sheet material of appropriate geometrical configuration, promote the formation of natural tissue thereon which is appropriate for the mechanical characteristics desired.

A prosthesis for an inadequate or diseased heart valve, the prosthesis being formed of a porous fabric comprising multifilament synthetic yarns supported on a plural-lobed frame. The frame has generally parallel legs each comprising a pair of rod portions. The fabric is inserted between the rod portions of the legs to form flexible leaflets. Each leaflet consists essentially of a textile of filaments having a substantial number of open interstitial spaces in the range of 20 to 40 microns evenly distributed throughout the fabric. The resulting composite structures are free of thrombogenic complications.

Prostheses for inadequate or diseased heart valves and blood vessels, formed of fabrics comprising multifilament synthetic yarns. For a heart valve the fabric is supported on a three-lobed frame. During manufacture, the fabric is subjected to a plural step compressive shrinking and crimping process to impart nonisotropic elastic compliance approximating the natural mechanical properties. The resulting composite structures are free of thrombogenic complications.

A semi-unitary protein product consisting essentially of a bundle of intermittently fused parallel protein fibers which closely resembles the fibrous structure of natural meat can be prepared by heating a protein-water mixture to form an extrudable plastic mass and then extruding the mass under pressure through a spinneret having a plurality of closely-spaced orifices therein directly into a gaseous medium to yield the desired product.

A frame system for heart valve prosthesis. A first frame has at least three generally parallel legs each comprising a pair of rod portions connected at one end and diverging at the other end as lobes respectively connecting with rod portions of others of said legs. The lobes form an aperture therebetween and the legs are adapted to receive the margin of a valve leaflet between the rod portions thereof. Thus, the leaflet may be secured to two adjacent legs and the interconnecting lobe so as to have a free edge extending between said adjacent legs. A second frame is adapted to nest with the first frame and comprises a rod formed to be substantially congruent with the interconnecting lobes, whereby the leaflets may be secured to and between the frames.

This invention relates in general to the formation of thick films having a biaxial molecular orientation. Such films are prepared in accordance with the present invention from rod-like extended chain aromatic-heterocyclic ordered polymers. Such films have high tensile strength, modulus, and environmental resistance characteristics. A preferred ordered polymer for use in the present invention is poly (para-phenylenebenzo bisthiazole), (PBT), a compound having the structure: ##STR1## The present invention is also directed to methods and apparatus suitable for producing biaxially oriented films, coatings, and like materials from ordered polymers, preferably PBT.
