Title: Polymeric bifocal lens production process
Inventor: CUTHBERTSON MATTHEW J
IPC: B29C35/02
Filed: 1992-11-26
Abstract: A polymeric bifocal lens production process including the steps of selecting a single vision lens or lens blank with a convex surface, and a bifocal mould with a smaller radius of curvature; roughening the convex surface of the lens or lens blank; assembling the mould and lens or lens blank with catalysed monomer between the mould and the lens or lens blank; holding the lens or lens blank and the mould in position relative to one another so that the lens or lens blank contacts the mould; curing the monomer; removing the mould and post-curing to relieve stress in the bifocal lens and to allow the cured monomer to shrink in a controlled manner thereby causing a power decrease in the bifocal segment, whereby the cured monomer cast on to the lens or lens blank is of higher refractive index than the lens or lens blank.

Filed: 1993-11-10
Abstract: The disclosure involves a bucket arch, used on dragline buckets, which has a pair of side sections and an arch center section disposed therebetween.  At least one lug is attached to the arch center section and exerts a force on the center section along a force axis.  In the improvement, the center section is angled with respect to the side sections and has an axis generally coincident with the force axis.

IPC: G06V30/146
Filed: 1992-08-27
Abstract: A transaction document reader reads image data on a transaction document. The image data includes marking areas employed by a user to record marks and includes characters. A sensor (52) senses, one row at a time, rows of image data as the document is transported across the sensor. Each row includes a number of pixel areas.  The pixel areas of the rows being aligned in columns. The sensor generates output signals representative of the pixel areas. The output signals are transformed into bit signals (72) representative of each pixel area. The bit signals are stored in image memory (62) which is organized into rows and columns of bit signals corresponding to the rows and columns of the pixel areas of the image data. The marking areas are located in image memory. The marks are identified in the marking areas while additional rows of bit signals are being stored and while other marking areas are being located by probing the bit signals in image memory. A specific area within image memory representative of a single character is also located. A neural network is utilized to recognize the character within specific area.
