This invention relates to novel polyacetylene compositions, a process of producing the compositions and a method for inhibiting tumors utilizing the compositions. More particularly, the compositions are antitumor polyacetylenes which are derived form marine organisms, i.e., the marine sponge Cribrochalina dura.

Range and/or profile of a test surface, particularly a submarine surface, are determined by passing a laser beam through a holographic grating structured to emit a divergent light beam defining a two dimensional array of dots in a predetermined pattern and projecting such beam on the test surface. A receiving device, e.g., video camera, ascertains the positions of the dots in the pattern reflected from the test surface and comparison is made of such positions relative to the positions of the res...

An improved key caddy device includes a rectangular strip of flexible sheet material that forms a case by overlapping the transverse edges and fastening them together with a first fastener assembly, e.g., a two-part snap button fastener, fixed to the strip. A key ring is carried, advantageously in a grommet, on the strip adjacent one of its longitudinal edges to receive one or more keys. A folded sheet bearing text, e.g., a printed road map, is enclosed within the flexible case and held therein ...

An improved outrigger device for a T-Top equipped motorboat that permits the outrigger thereof located above the T-Top to be moved from a stowage position to a trolling position and vis versa by an occupant of the boat standing in the shelter of such T-Top includes a tubular member having an upper end portion and a lower end portion joined integrally to a central portion that extends through such T-Top with its upper end portion positioned above the T-Top and its lower end portion positioned bel...

This invention relates to antitumor compositions, and a method for inhibiting, remitting or controlling the growth of tumors or tumor cells utilizing antitumor compositions. More particularly, the antitumor compositions comprise, as active ingredient, an antitumor effective amount of halogenated chamigrenes extracted and derived from red alga and sea hares which diet upon red alga.

A system for applying pressure sensitive adhesive labels from a feed web with high position precision onto flat uniform size articles mechanically links the advance of the article to be labeled and the advance of the current label to be applied in unison, so that forward advancement speed of the article and the current label are matched exactly, independent of any speed variation in the application system. This is accomplished using a label following member that comes to rest at the trailing edg...

New types of fiberoptic microbend sensors are in the form of flexible tapes wherein single or multiple layers of mechanically tough flexible tapes form two outside surfaces of the sensors including between them one or more continuous elongated optical fibers, a variety of monofilaments, wires, threads, meshes, ribbons and or like elements to act as deformers to the optical fiber and sufficient adhesive material to form a permanent flexible tape structure. Additional layers of film, optical fiber...

A parallelogram boom device for mounting agricultural implements has a parallelogram arrangement of a first upper beam horizontally and longitudinally aligned with a second upper beam plus a single lower beam longitudinally aligned with the first and second upper beams, but at a lower horizontal level. A first hydraulic piston unit acts via a bridle to raise and lower the parallelogram arrangement relative to the ground. An agricultural implement is attached at one end to a mounting arm supporte...

Sheathed knives are disclosed that have a blade that is ejected via a button triggered spring longitudinally from the sheath into a locked use position in which the sheath then serves as the handle for the blade in the nature of a dagger, an elongated handled rod that slides within the sheath to draw the blade from its use position back into the sheath where it is automatically locked in a spring loaded sheathed position for triggered release into its use position and safety features to prevent ...

A new method for the production of decorative designs on substrates, e.g., furniture and building walls, basically includes the steps of (a) providing a design printed on a flat release sheet, the design comprising a picture side in contact with the release surface and an exposed back side, (b) applying to an exposed surface of a substrate an imprint layer of imprint material, (c) contacting the exposed back side of the printed design with the external surface of the substrate layer, (d) imprint...
