The aqueous solution of a polysaccharide from the group consisting of hyaluronic acid and its salts, chondroitin sulfate and agarose is enhanced by the addition of albumin to provide uniform wetting over the anchor film on the plastic.

Abstract: Siloxane-containing polyimides, useful as conformal coatings for electrical devices, can be synthesized via a novel Diels-Alder reaction in which bis-maleimide derivatives are polymerized with siloxane-containing bis-furan derivatives. The Diels-Alder adduct can be aromatized, and applied as a coating to a mineral substrate. The aromatized, polyimide coating can be cured thermally without additional cyclization on the substrate.

Abstract: Dot matrix method of entering and transmitting script. For example, Chinese script in the form of a character or ideograph is written upon a dot matrix "keyboard", then registered and stored within a conventional computer memory. As desired, the computer may print the individual Chinese character or a plurality of Chinese characters, constituting the entire memory, upon a dot matrix printer.The present method is characterized by its capability of registering the entered script or character as digital information within a latch matrix, then transferring the digital information from the latch matrix as groups of bytes into an input/output control. The accepted digital information may be transmitted from input/output control to random access memory, read only memory, a microprocessor controller or external communications.

An optional ash pan and fire box door may be mounted beneath the fire grate. The entire assembly may be broken down and nested together for carrying either by pivoted handle or within a backpack or the like.

Abstract: A chain turbine system of the type including pairs of chains supporting a plurality of pivoted deflection buckets. The pairs of chains are suspended across a moving stream, so that a lower portion of the chains and the deflection buckets travel through the stream at right angles to the current and an upper or returning portion of the chains and deflection buckets is out of contact with the stream. Modifications of the invention include affixing one or more guide wheels to the discharge ends of the deflection buckets such that the guide wheels engage a stabilizing track, while traversing the stream bed as the lower driving portion of the chain, and on the return upper portion of the chains the guide wheels engage a stabilizing cable or rod. Also, when the stream current is scant, the system may be built with a pressure or accumulation tank across the stream so that the flowing stream may be accumulated, then discharged downwardly through discharge ducts to the deflection buckets.
