This is a display rack assembly particularly designed for displaying greeting cards for inspection by prospective customers and which is constructed of a plurality of elongated sections each of which includes a front retaining flange at the forward edge portion of a supporting shelf and which has an upwardly extending back panel with a connecting hook at the top thereof for receiving the front upstanding retaining flange 13 to provide a connection between two adjacent sections.

Portable association croquet wicket practice assembly of three-point playing surface contact, defining a simulated target wicket wherein upright legs are fixedly spaced apart in regulation measure by a topmost transverse crown, the free ends of the legs being supported by surface contact, the target wicket being ballasted and balanced rearwardly by two interconnected weights, a first weight being elevated and fixed relative to the crown to apply vertical and horizontal moments to the wicket, a s...

A process for obtaining purified hemicellulose, cellulose and cellulose-hemicellulose complexes comprising the steps of adding alcohol to caustic liquor from alkali extraction of fiber to precipitate the hemicellulose and the simultaneous, or about simultaneous, density separation of hemicellulose from the caustic liquor. The alcohol transforms the soluble high molecular weight hemicellulose into a light precipitate which floats on top of the caustic liquor solution. The caustic liquor can be su...

This invention provides a process for preparing polyolefins by polymerizing or copolymerizing olefins using as the catalyst a titanium compound-containing solid component and an organometal compound, said solid component comprising a substance obtained by copulverizing (1) magnesium halide and/or manganese halide, (2) an organic halide compound, (3) a chain or cyclic silicone compound with a recurring structural unit represented by the general formula ##STR1## wherein R' and R" respectively repr...

A test strip having at least one patch thereon and intended for use in occlusive epicutaneous testing in order to detect contact allergy to formaldehyde. The characteristic feature is that on at least one of the patches the test substance is a reversible N-formaldehyde derivative of succinimide which is formulated in a dry buffered vehicle.

The invention concerns a process for extracting hemicellulose from fiber, such as corn fiber. The process comprises agitating at least fiber, caustic and optional added water at a moisture content from about 10% to about 60% at high speeds in a highly fluidized state. The process substantially instantaneously extracts the hemicellulose from the fiber. Heat may be applied in the process to extract and dry the hemicellulose substantially simultaneously.

The present invention provides a process of producing a water-soluble hemicellulose comprising a starch removing stage, an extraction stage and a neutralization and desalting stage and the use of the obtained water-soluble hemicellulose as a health food.

A rotary lawn mower mounted on a tractor is equipped with a blower operable to move grass clippings from the mower into a pair of collection bags. The blower has an impeller located within an upright housing attached to a side of the mower. A belt and pulley drive connects a horizontal impeller shaft to an upright blade shaft of the mower to rotate the impeller concurrently with the grass cutting blades of the mower. The rotating impeller draws grass clippings and other loose material from the m...

An apparatus for providing electrostatic discharge protection includes a plurality of conductive circumferential extensions defined by overlapping circular voids between a first conductor surface and a second conductor surface.

Biodegradable thermoplastic polymer blend compositions are presented in which a first polymer and a second polymer are intimately associated together in a uniform, substantially homogeneous blend. The second polymer of the composition acts to facilitate biodegradation of the composition, and of shaped articles manufactured therefrom, at a rate which is enhanced over that of the most slowly biodegrading individual polymer component of the composition. The composition may further comprise a polysa...
