Abstract: Polypropylene and other polyolefins are rendered flame retardant by the addition of a phosphonate ester having the following formula: ##STR1## wherein a is 0, 1 or 2, b is 0, 1 or 2, c is 1, 2 or 3 and a+b+c is 3; R and R' are the same or dissimilar and are alkyl, alkoxy, aryl, aryloxy, alkaryl, alkaryloxy, aralkyl, aryloyx-alkoxy, or aralkoxy, wherein the alkyl portion of these groups may contain hydroxyl but no halogen and the aryl portion may contain chlorine bromine and hydroxyl groups; R.sup.2 is alkyl, hydroxyalkyl, or aryl; R.sup.3 is lower alkyl (C.sub.1 -C.sub.4); and a wetting agent penetrant. The presence of the penetrant promotes penetration of the retardant composition into the polypropylene. This fire retardant composition is particularly useful in polypropylene fibers and fabrics particularly where the fibers are woven into a matte.

Abstract: Grooves or channels are formed along the edges, and/or at other selected locations, of a guitar, of other musical instruments; as might be done in purfling and binding for such instrument. A fiber-optic bundle is laid into the groove and overlayed with a veneer of suitable wood, or other appropriate materials, but in such a manner that ends of selected fibers are aligned with and/or extend through suitable apertures formed through the veneer overlay. The individual fiber-optic bundles are then gathered into a main fiber-optic trunk line which is directed through an entry channel and away from the instrument; terminating at a source of illumination.

Abstract: A loose-leaf binder mechanism comprises top and bottom covers. A backbone connects the top and bottom covers. A binding mechanism includes a detachable longitudinal bar. The detachable longitudinal bar has a projection with a groove thereon extending therefrom. A channel guide is affixed to one of the covers. A flat latching bar is reciprocally received within the channel guide for cooperating with the projection to join the binding mechanism to one of the covers. An indented structure on the channel guide substantially restricts the movement of the latching bar to reciprocal movement.

Abstract: A part, such as finial or the like, is molded of plastic material so that during the molding process there is formed within the part a bore having internal threads formed therein for a predetermined extent of its length and so as to terminate a predetermined distance in from the entry end into the bore from the base of the part. A circular recess, surrounding the entry end of the bore, and a number of rectangular indentations, are also formed in the base during the molding of the part; which is molded with the parting line of the molded parts in a plane that includes the axis line of the bore and the internal threads.The molding machine parts are formed to insure uniform and precise threads by locating the cavities, within which the parts are molded, all equally distant from the gate; and by forming cooling water tracks in predetermined positions with respect to the mold parts and cavities.

Abstract: A three-legged chair having two side legs and a centrally disposed rear support leg wherein, the seat cooperatively moves with respect to the three legs in folding the chair. The third leg folds closed so as to fit between the parallelogram-shaped two side legs, and the folded closed chairs may then be stacked as flush-fitting parallelograms. The sides of the side legs are formed with complementary connecting parts so that the folded open chairs may be attached so as form a row or pew.

Abstract: The upper and lower jaw members and intermediate connecting member of a dental model articulator are molded from suitable plastic as an integral unitary whole; with the jaw members spaced from each other, by the intermediate connecting member, a distance comensurate with the dental models to be mounted on the articulator, and so that the upper jaw member articulates with respect to the intermediate member and lower jaw member to facilitate relative positioning of, and the performing of work on, the dental models. An over-center toggle-type-hinge is integrally molded between the upper jaw member and the intermediate connecting member to provide for articulation of the upper jaw member.

Abstract: The reversed passive hemagglutination test (RPHA) for the detection of hepatitis B surface antigen (HB.sub.s Ag) is improved by the recognition that the speed of movement towards the periphery of a centrifugal field by immunologically aggregated solid phase support particles, increases proportionally with the amount of antigen present. It is further recognized that this dynamic study can be performed objectively and in an automated fashion by equipment such as the miniature centrifugal fast analyzer. The test performed in this manner and known as "reversed passive hemagglutination by minature centrifugal fast analysis" (RPHA/MCFA) is highly specific and eliminates the need for subsequent confirmational studies. Preliminary studies confirm a sensitivity comparable to other third generation tests.

Abstract: A loose-leaf binder is disclosed having a pair of separable cover members with rib portions and a centrally disposed fastening sleeve assembly disposed for insertion through a central aperture in the rib. An outer sleeve of said fastening sleeve assembly is tapered at one of its extremities to coact with ball locks carried by an inner sleeve member which is slidably disposed for limited longitudinal movement within said outer sleeve, and which is hollow at one of its extremities to receive the locking pin. The operating extremity of the inner sleeve member is provided with a transverse aperture which passes diametrically therethrough to receive an operating member in the form of a ring which is sized so that it will not interfere with closing of the cover no matter what the rotative position of the ring when disposed in the inoperative position which is flat, parallel to and in contact with the rib of the closed binder.

Abstract: A game device for chance play is disclosed which comprises:a base;a body rotatably mounted on said base and being formed with a plurality of holes of a first size and another hole of a second size;a plurality of members sized to receive in said plurality holes but not fitting into said another hole; andanother member sized to be received in both said plurality of holes and said another hole.The game device is played by inserting all the members in the plurality of holes but not the differently sized hole, and then spinning the body. When the body stops spinning, one player selects a member and tries to insert it into the differently sized hole. The game continues until one player selects the one member that fits.
