Abstract: An apparatus and method for mounting a plurality of plates onto a carrier sheet includes a table mounted on a stationary base, each plate having a first and a second registration mark thereon. A first camera assembly is moveably attached to a support adjacent the table and is connected to a first video monitor for viewing the first registration marks. A second video camera is moveably attached to the support adjacent the table and is connected to a second video monitor for viewing the second registration marks. Linear actuators are connected to the first and the second camera assemblies and to the table for independently moving each camera assembly relative to the table. A motion controller is connected to the linear actuators for sending moving signals thereto, and generates at least two moving signals corresponding to the two registration marks for each plate.

Abstract: Disclosed herein are copolymers of tetrafluoroethylene and n-alkyl trifluorovinyl ether which further contain either curesite repeat units and/or iodine. Such curesite repeat units, upon exposure to free radicals, may crosslink the copolymers. The iodine is introduced by carrying out free radical polymerization in the presence of an organic iodide chain transfer agent. The polymers according to the invention are especially useful as elastomers and/or as molding resins for articles or parts that may be exposed to a basic environment. The preparation of such polymers by aqueous emulsion polymerization is also disclosed.

Abstract: Transform-limited ultrashort optical pulses are obtained by sending into a dispersion-shifted optical fibre pulses of such duration and intensity as to produce self-phase modulation. The pulses are also made to travel through a conventional fibre with suitable dispersion and are subjected to optical filtering, so as to compensate, for a particular peak power, the phase effect due to the chirp. Pulse peak power is selected so as to coincide with the vertex of the parabola plotting the square of the duration of the outgoing pulse versus the peak power of the incoming signal.

Abstract: Amorphous copolymer of fluoromonomer, such as tetrafluoroethylene, with vinyl ester, such as vinyl acetate, having a substantially uniform composition is made by aqueous dispersion polymerization by maintaining essentially constant the proportion of the fluoromonomer and vinyl ester copolymerizing with one another. In one embodiment, this proportion consistency is obtained by reducing the agitation rate of the aqueous polymerization medium during the copolymerization reaction at constant fluoromonomer feed pressure within the polymerization reactor.

Abstract: A secondary security garage door is provided that is attached to and operates behind a primary garage door. The security door is made up of multiple panels composed of an outside frame supporting a wire mesh material. The security door rides along a separate guide rail adjacent to the primary garage door guide rail When assembled and installed, these panels form a barrier that prevents unwanted intruders access to the garage, or the escape of pets. This also allows for the free flow of outside air into the garage, thereby solving the problem of overheated garages during the warmer seasons. The secondary security door is provided with an interlocking system. This system allows both doors to automatically be locked together and ride up and down the rails in tandem. This feature allows the door operator to lift the security door by closing the primary door, which will then engage the interlocking system, thus, allowing the doors to move together.

Abstract: Terephthalic acid is produced by oxidation of para xylene, purified in an aqueous phase and recovered by precipitating a purified product from the aqueous phase, the aqueous phase mother liquor is then cooled or evaporated to produce a further less pure precipitate and a second mother liquor and the less pure precipitate is returned to the reaction medium and/or the water of the second mother liquor is used to dissolve the crude solid and/or the second mother liquor is treated to recover water which is used to wash the precipitate recovered from the aqueous solution. The process produces better yields of terephthalic acid, reduces the use of water and reduces problems in the disposal of polluted waste water.
