Abstract: A massage device includes a drive motor, a drive wheel operatively coupled to the drive motor to rotate upon energization of the drive motor, the drive wheel having an eccentric post situated thereon, a movable bracket that includes one or more massaging elements rotatably mounted on the bracket, a rotational movement-to-linear movement translation coupler operatively coupled to the drive wheel and to the movable bracket, and an exterior sleeve defining a handle for a user to hold the massage device. When the drive motor is energized, the drive motor causes the drive wheel to rotate, the rotating drive wheel causing the movable frame and the one or more massaging elements to move with a linear, reciprocating motion.

Abstract: A coaxial surge protector includes a housing in which is situated a transmission line in the form of a two-sided printed circuit board. The surge protector includes input and output signal connectors mounted on a housing and connected to the transmission line, and a gas discharge tube electrically coupled between the transmission line and circuit ground. A thermally activated shunt assembly is thermally coupled to the gas discharge tube and senses when the gas discharge tube is in an overheating condition. Upon such condition, the shunt assembly provides an electrically conductive shunt in parallel with the gas discharge tube to divert current flowing through the gas discharge tube to flow through the shunt assembly to ground in order to minimize further overheating of the gas discharge tube.

Abstract: An arrangement for supporting an optical fiber and related optical components in a raised position above a surface of a printed circuit board on which electrical components are mounted includes a support which defines an endless, oval raceway for receiving one or more optical fibers, legs mounted on the support and secured to the printed circuit board for supporting the raceway defining support above the surface of the printed circuit board a predetermined distance so that the support does not interfere with the electrical components mounted on the printed circuit board, and one or more ramps joined to the raceway and extending from the raceway substantially to the surface of the printed circuit board. The ramps provide support for the optical fibers over portions of the fibers where they are coupled to an opto-electronic transmitter or receiver mounted on the printed circuit board.

Abstract: A molded plastic cosmetic contact lens made in a repetitive manner comprising a cosmetic pattern of clustered networks of interconnected thin colored lines radiating from and about the periphery of the pupil portion in a direction inclined towards and in contact with the periphery of the iris portion and residing within the iris portion. The lens can be made by molding in a manner that the cosmetic pattern becomes part of the body of the lens.

Abstract: A process for the manufacture of a molded contact lens containing a transparent central visual region circumscribed by a colored iris portion which comprisesa. coating a colored liquid which is either curable or thermoplastic in a mold for making a contact lens onto a surface thereof where the iris portion of the lens is formed to produce a colored film thereon which film contains a surface exposed to the interior of the mold and a surface in contact with the mold,b. charging the mold with the resin used to form the body of the lens while maintaining the colored film in the iris portion and configuring the resin about the colored film whereby the surface of the film becomes integral with the body of the lens and the surface of the film becomes part of the outer surface of the lens when the molded lens is removed from the mold.

Abstract: An improved mold apparatus and spin casting method adapted for use in the molding of precisely configured articles, e.g., a contact lens, from a liquid polymerizable reaction mixture containing at least one volatile component is disclosed. Loss of this volatile component from the reaction mixture is prevented by providing a separate reservoir filled with a liquid volatile substance which volatilizes and fills the space above the liquid polymerization mixture.

Abstract: A cutting device and method for the precision trimming of a symmetrical portion of the peripheral edge of a centrifugally cast lens secured within a cavity of a female mold without the need for extensive and complex prior alignment of the cutting tool with the lens.

Abstract: An apparatus and method for feeding molds to a device for centrifugally casting a plurality of axially symmetrical or asymmetrical articles such as lenses, disc valves, and the like on a continuous basis.

Abstract: A centrifugal casting device and method employing a rotatable polymerization column adapted to accommodate a plurality of vertically aligned molds and being associated with an arrangement of advancing means and mold feeding means which are synchronized to intermittently and automatically advance a mold containing a polymerizable or curable composition in the mold cavity over the polymerization column and then automatically force feeding said mold into the polymerization column.

Abstract: A device for the centrifugal casting of articles in a rotatable polymerization column which includes retaining means disposed in the lower end of the column for communicating with a mold therein whereby the rotational speed of said mold and other vertically arranged molds above it are made substantially synchronous with the rotational speed of the column.

Abstract: A device and method for spin casting articles, such as lenses, employing a rotatable polymerization column in conjunction with a plurality of molds such that the column is adapted to accommodate a plurality of gravity fed molds in a loose mating engagement that insures rotation of the molds to be synchronized to the speed of rotation of the column to produce quality spun cast articles.

Abstract: A device and method for spin casting articles such as lenses employing a polymerization tube in conjunction with a plurality of molds such that the tube is adapted to accommodate the plurality of molds in an interference fitting and sliding relationship so that rotation of the polymerization tube will cause the molds to rotate at the same speed while maintaining the concentricity of the molds to the spinning axis of the tube to produce quality spun cast articles.

Abstract: Plastic contact lenses are formed in a casting process in which the required amount of lens-forming material is charged into a mold half, the mating lens half is inserted but only far enough to contact at least the surface of the lens-forming material. Next the inserted part is allowed to dwell or is slowly withdrawn for a sufficient distance to cause the liquid lens-forming material to move to the center of the two molding surfaces and to approximate a column between the two molding surfaces. The moveable mold portion is then quickly inserted into the mold pushing the lens-forming material uniformly outwardly and displacing any air between the two molding surfaces to form a contact lens devoid of air bubbles and entrained air.

Abstract: An improved gas feed means adapted to accommodate and secure the lower end of a polymerization column for synchronous rotation therewith and adapted to supply a controlled amount of a gaseous medium, such as nitrogen, into and through the rotating polymerization column so as to purge any undesirable gas within the polymerization column that could adversely affect the quality of the objects being centrifugally casted.
