Abstract: A novel thermopolymer material adapted for use in thermal stereolithography. More particularly, a thermopolymer material comprising a mixture of: a low shrinkage polymer resin; a low viscosity material such as paraffin wax; at least one microcrystalline wax; a toughening polymer; a plasticizer. Alternative embodiments further include components to improve the materials ability to transfer heat and to improve strength. The subject material, together with the described process greatly reduce part building distortions while retaining desirable toughness, strength and jetting properties.

Abstract: The placing of an artificial intraocular lens device (IOL) in the anterior chamber of the eye (in front of the iris) for treating myopia. The intraocular lens device includes a meniscus style lens which has a plano anterior surface and a concave posterior surface. The edges of the lens are rounded off and the peripheral portion of the lens is considerably thicker than the central portion of the lens. The lens is a minus (negative) refracting lens. The lens is suspended in the anterior chamber by three or four carrying angles or haptics having solid footplates at their ends for anchoring the device in the anatomic angle of the eye. The solid footplates are sized to prevent tissue overgrowth and resulting synechia after placement, additionally facilitating subsequent removal of the lens device from the anterior chamber if necessary. A ridges lens glide is also provided to facilitate insertion of the lens device into the anterior chamber during implantation.

Abstract: An underwater light assembly for internal illumination of swimming pools and the like which operates on batteries and does not require any externally-provided current. A partitioned compartment is detachably engaged within and against a transparent dome. The compartment houses weights to keep the assembly submerged in a pool of water. The compartment also houses the batteries and a power assembly for providing current to a lamp socket. The lamp socket is suspended within the compartment. A detachable seal is provided to seal the compartment within and against the transparent dome. A metal contact plate is provided on the detachable seal such that, when the seal is inserted and seals the compartment within and against the transparent dome, an electrical connection is completed and the power assembly supplies current to the lamp socket.

Abstract: An insert for tubeless tires to maintain vehicle control and prevent tire collapse in the event of puncture or other loss of air pressure. The insert has a toroidal center core of solid material, a foam casing of compressible but resilient foam material annularly surrounding the cylindrical core, and a thin outer flexible shell annularly surrounding the casing.
