Abstract: The present invention relates to a method of coating a lens, such as a segmented multifocal lens. The method includes, providing a lens support (1), which is in the form of a ring, that includes a central axis (11), an outer wall (14), an inner wall (17) that is positioned between the central axis and the outer wall, an upper beveled surface (20) that converges downward toward the central axis, and a lower surface (29). The method further includes positioning a lens (3) such that an outer edge (74) of a forward surface (65) thereof abuts a portion of the upper beveled surface of the lens support. At least one coating composition is applied over the rear surface (68) of the lens, so as to form a coated lens (3?) having at least one coating layer (89) over the rear surface thereof.

Abstract: A method of forming a photochromic segmented multifocal lens is described. The method involves, forming a segmented multifocal lens blank by molding, in which the segmented multifocal lens blank has a front surface and a rear surface. The front surface of the segmented multifocal lens blank includes a segmented optical power addition portion. The method further includes, grinding the rear surface of the segmented multifocal lens blank, thereby forming a segmented multifocal finished lens having a front surface and a rear surface. The front surface of the segmented multifocal finished lens includes the segmented optical power addition portion. The method additionally includes, forming a photochromic coating layer over at least a portion of the rear surface of the segmented multifocal finished lens. The photochromic coating layer includes at least one photochromic compound.

Abstract: The present invention is directed to coatings that provide improved retort and tropical decay resistance for use on metal food containers. The coatings generally comprise a carbamated polyol formed by the reaction between a polyol, an alkylene oxide and an alkyl carbamate. A crosslinker reactive with the carbamate functionality is used to react with the carbamate moiety. Methods for improving retort resistance and resistance to tropical decay are also disclosed, as are substrates coated with the present compositions.

Abstract: The controller is a logical network which, when interfaced with a mechanical system or an electromechanical system, will cause the output variable of the system to closely follow any command signal received. It comprises shift registers, memory banks, accumulators, arithmetic units and preferably no software. Universal Controller keeps the error between the output of the model and the output of the control system small, regardless of the transfer function of the controlled system by adjusting a number of gains in its internal feedback loop in accordance with that error. It therefore can be applied to an arbitrary electromechanical system without prior knowledge of its transfer function.

Abstract: The Controller is a logical network which, when interfaced with a mechanical system or an electromechanical system, will cause the output variable of the system to closely follow any command signal received. It comprises shift registers, memory banks, accumulators, arithmetic units and preferably no software. The device works in two stages. In the first stage it identifies the unit-impulse response of the system piece-by-piece while using the accumulated information to control the system at the same time. In the second stage it continually readjusts the stored information at each clock pulse by comparing the observed output signal and the command signal, while generating the required control variable based on the updated information. Its operation incorporates a learning process which emulates a simple form of human intelligence.
