Abstract: A layered tubing for conveying a non-toxic fluid comprises an inner layer having an inner surface adapted for exposure to the fluid, the inner layer consisting essentially of a polyester comprising units of the formula C10H8O4, and an outer layer comprising a thermoplastic polymer, the outer layer being bonded either directly or indirectly to the inner layer. Such a tubing is useful for conveying non-toxic fluids such as water, syrups and beverages. The polyester can also be used in the form of a film for packaging solids suitable for human consumption, such as food and medicaments.

Abstract: A dental device for weight control is disclosed which comprises a body having an upper side and a lower side, a protrusion extending from the lower side for extending into an oral cavity to reduce a volume of the oral cavity, a front edge positioned between the upper side and the lower side contoured to fit against teeth, and a back edge positioned between the upper side and the lower side, the back edge for bearing against a roof of a mouth.

Abstract: A dental device for preventing a sleep disorder is disclosed which comprises a body having a lower teeth engaging surface, a central portion having a tongue engaging surface for holding a tongue down, and a pair of front ball clasps and a pair of back ball clasps for retaining the body to a lower jaw of an individual.

Abstract: A camphor container assembly is disclosed which comprises a card having a front side, a container positioned on the front side of the card with the container having an opening and an interior portion, a quantity of camphor positioned within the interior portion of the container, and an insertion device for inserting the container into a nasal cavity.

Abstract: An articulator for positioning a pair of dental casts relative to each other is disclosed which comprises a pair of members adapted to being connected to each other for pivotal movement relative to each other, each member comprising a central portion having a hooked end and a forked end with the forked end having an outer tine, an inner tine and a pin connected between the tines, and a ball connected to the central portion by a spline.

Abstract: A track section for pivotally interconnecting sections of toy vehicle track comprising at least two pivotally attached segments, each segment having a top surface, a bottom surface, and spaced apart ends. The track section further comprises cooperating rails that form a substantially continuous path for guiding the movement of a toy vehicle when one segment is positioned at an angle relative to another of the at least two segments. The rails partially define a pair of spaced apart parallel channels along with a median on the top surfaces of the segments. The track section includes a coupling device comprising a prong protruding from one end of one of the segments along a central longitudinal axis, and a socket formed in one end of the other segment along a central longitudinal. The other ends of the segments include a connecting device comprising a cooperating flange and recess for pivotally connecting the segments wherein the flange of each segment is received within the recess of the other segment.
