Abstract: A simplified building structure that can be extruded out of plastic to be used as inexpensive substitutes for walls, ceilings, roofs, posts, and other structural components. The structure includes elongated male and female means to connect two of the structural components together securely, either by longitudinally inserting one into the other or by snapping the male component transversely into the female component. For this purpose, the male component has resilient flanges that can be forced into a female slot, thereafter to spring apart to engage overhanging parts of juxtaposed edges of the slot to lock the two components rigidly together. Preferably, the flanged male spline is formed on top of a ridge, the side edges of which engage the juxtaposed edges of the female slot to prevent any transverse movement of one of the components relative to the other.

Abstract: A method of playing a racing board game. The board comprises a race course having a starting position, a finish line and six lanes. The lanes are divided into a plurality of spaces. There are six distinguishable playing pieces and each player is assigned a playing piece and a lane. Six standard cubical dice, each die numbered from "1" to "6" to correspond to the six playing pieces, are used to determine movement of the playing pieces. The board further comprises shaded spaces on the lanes and six separate storage locations for placing chips. The storage locations correspond to the six finishing positions, e.g. 1st place, 2nd place, . . . , 6th place. When a playing piece lands on a shaded space, that player, to his advantage, must place a chip in a storage location in which he thinks his piece will finish the race. As the race progresses, the player whose piece crosses the finish line first is given all the chips stored in the storage location corresponding to 1st place.

Abstract: A programmable sewing machine having movable work holding means, first and second separable button holding means, button supporting means movable into proximity with the button holding means and means to move the button holding means toward the sewing machine bed.

Abstract: This invention concerns a method of treating water from a container with ozone. The water is withdrawn from the container in a main stream, then passed through a pressure-reducing means, and returned to the container. A part of the main recirculating stream is separated into a second stream. The second stream is treated with ozone and held for a sufficient period of time to allow substantially all of the ozone to permeate into the water. The second stream is then re-introduced into the main stream or directly into the container.

Abstract: Microcapsules having a high loading factor of core material are formed as separate, reservoir microcapsules by coating solid core particles first with a thin, conformal layer of parylene and then with a layer of thermoplastic material.
