Abstract: The present invention is directed towards a series of removable bulkheads which surround and protect immovable building fixtures such as sprinkler and plumbing lines, heating and ventilation ducts, electrical and telecommunications wiring. A single bulkhead is generally comprised of a vertical panel and a horizontal panel. The bulkheads attach to preexisting ceilings and walls and provide a quick and cost effective method of concealing fixtures and allow easy access to renovate or repair the fixtures.

Abstract: A reconfigurable banquet table includes a table top, a plurality of retaining clips, and two or more base members. The table top bottom surface includes a plurality of pairs of openings. A corresponding plurality of retaining clips are secured thereat. Each retaining clip includes a first flange and a second flange extending from a plate. Each base member includes first and second legs connected a set distance apart. The first and second legs of each base member are received in one pair of the table top openings, and releasably secured therein by the corresponding retaining clips, with one side of each of the first and second legs engaged by the second flange of the respective retaining clip, to cause deflection of the second flange to provide suitable retaining forces. Easy removability of the base members permits interchangeability without requiring tools, for greater functional/aesthetic versatility, easier transport, and more compact storage.

Abstract: Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self activating and self dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments.

Abstract: Alcohol and ester resistant thermoplastic blends are described. The blends include a clay and a triphenyl phosphate or a diphosphate nanocomposite blended with the thermoplastic.

Abstract: An apparatus for mitre cutting an elongated moulding to produced a mitred end, and for cutting a groove in the end comprises a frame having longitudinal and lateral extent, and a laterally elongated table on the frame to receive and support a first portion of a moulding extending longitudinally; a first clamp on the frame for clamping the moulding to a first portion of the table; a first carriage supported by the frame to travel laterally back and forth, relative to the table; a first rotary disc cutter and a drive therefor supported on the carriage for cutting the clamped moulding laterally therethrough to produce the mitred end, as the carriage travels laterally; and a first router and a drive therefore supported by the carriage for laterally penetrating the mitred end of the moulding as the carriage travels laterally, for cutting the groove in the mitred end.

Abstract: Apparatus for cutting grooves in moulding members adapted to have their ends joined in L-shaped assembly by an L-shaped bracket, the apparatus comprising:(a) a first base, and a first guide surface on the base to engage the back side of the moulding thereby to position the moulding directionally laterally, and to extend directionally longitudinally,(b) a first stop to engage and position the mitred end of the moulding, thereby to position the moulding longitudinally,(c) clamp means movable to engage the positioned moulding and retain the moulding on the base,(d) a first router and a rotary drive therefor, the router projecting into lapping relation with said mitred end of the moulding,(e) means to displace the first rotating router relative to the base to directionally sidewardly engage and penetrate the mitred end of the moulding, thereby to produce said groove, the router thereafter being sidewardly removable from said groove,(f) and means to adjustably position the base, laterally, thereby to position the

Abstract: Apparatus for cutting an insert groove in a longitudinally elongated moulding having a backside and mitred end includes:(a) a first base, and a first guide surface on the base to engage the back side of the moulding thereby to position the moulding directionally laterally, and to extend directionally logitudinally,(b) a first stop to engage and position the mitred end of the moulding, thereby to position the moulding longitudinally,(c) clamp structure movable to engage the positioned moulding and retain the moulding on the base,(d) a first router and a rotary drive therefor, the router projecting into lapping relation with the mitred end of the moulding,(e) and guide structure to guide bodily displacement of the first rotating router relative to the base to directionally engage and penetrate the mitred end of the moulding, thereby to produce the groove, the router thereafter being sidewardly removable from the groove.
