Abstract: Novel dendritic polymers are employed to clinically seal or repair wounds and treat traumatized or degenerative tissue. Novel crosslinkable biopolymers such as dendritic macromolecules are used in vitro, in vivo and in situ to treat ophthalmological, orthopaedic, cardiovascular, plastic surgery, pulmonary or urinary wounds or injuries. The crosslinkable dendritic macromolecules can be fabricated into cell scaffold/gel/matrix of specified shapes and sizes using one-photon and multi-photon spectroscopic techniques. The crosslinked polymers can be seeded with cells and used to repair or replace organs, tissues or bones. Alternatively, the polymers and cells can be mixed and injected into the in vivo site and crosslinked in situ for organ, tissue or bone repair or replacement.

Abstract: A hydraulic manifold is provided on a primary mast section which maximizes the commonalty of hydraulic components used in the hydraulic lift control systems of two and three stage mast assemblies used in lift trucks. Two and three stage mast assemblies are illustrated using primary mast sections which are identical and using secondary mast sections which are nearly the same.

Abstract: A hose tensioning device is provided to suitably tension a flexible hydraulic hose used on a lift truck so as to reduce damage that might otherwise occur should the hose become slack. The hose tensioning device serves as a hydraulic connector and its outer component is a protective housing for the biasing spring by which the hose is tensioned.
