Assignee:

Omniglow Corporation - Novato CA

International Classification:

C09K 300
F21K 200

US Classification:

252700

Abstract:

A plasticized vinyl halide or vinylidene halide polymer structure useful in a chemiluminescent lighting device is disclosed wherein said structure is prepared from vinyl halide or vinylidene halide polymers. The plasticizer is preferably a dibutyl phthalate solution of a chemiluminescent oxalate and a fluorescer that is incorporated into the structure. Addition of a hydrogen peroxide activator solution to the structure produces the glow of chemical light. The structure has good strength, flexibility, porosity and absorbance of the activator solution. A method for the preparation of the structure is also disclosed.

International Classification:

G06F 314

US Classification:

364523

Abstract:

A digital typesetter for imaging graphics quality characters of a specified font. The typesetter includes an electronic data processing system which receives first digital data defining the identity, form, size and placement of characters to be typeset; receives second digital data defining the contour of each character to be typeset with respect to a normalized encoding set of first and second coordinates; and produces third digital data defining the character boundaries intersecting a raster (scan) line. This third digital data, for at least a portion of the raster line extending the width of several characters, is temporarily stored in a raster line storage buffer. A character imaging device, connected to the line storage buffer, is provided to image successive raster lines on a print medium. Drive means are also provided for moving the print medium in a direction transverse to the direction of the raster (scan) line.

Inventors:

Martin Cohen - Maywood NJ

Assignee:

Latin Percussion, Inc. - Palisades Park NJ

International Classification:

G10D 1306

US Classification:

84402

Abstract:

A percussion instrument includes a sound chamber having a cavity therein with at least one opening thereinto, support means secured to the chamber within the cavity, a resilient, elongated member disposed within the cavity of the chamber, one end of which is free-standing and the other end of which is coupled to the support means, a knocker secured to the free end of the resilient member, and a vibratory, elongated rod which is secured to the sound chamber. The rod includes a handgrip along one portion of its length for imparting sustained vibrations to the resilient member and, in turn, the knocker, so that the knocker will strike the walls of the sound chamber to thereby produce a percussion sound. The instrument is particularly suitable for simulating the sound of a jawbone percussion instrument, used for Latin American music.
