Title: Optical filter for character recognition - with pattern based on weighted intensities of Fourier transformations to improve resolution
Inventor: FRANKE KURT
IPC: G06V10/88
Filed: 1976-09-25
Abstract: An optical filter, for use in a character recognition system using Fourier transforms of the images of the objects, is based on the selection of two groups of possible patterns. The distribution of the transparent and opaque sections of the filter is determined by being transparent at points where the ratio of the sums of the weighted intensities of the Fourier transforms of the first group to the sum of the weighted intensities of the transforms of the second group is greater than unity. The result is to improve the resolution between possible patterns with similar transforms, and to simplify the equipment overall.

Title: Thermostat with reset arm - holding contact arm in open circuit position for resetting by hand
Inventor: UCHIYA TOMOYOSHI
IPC: H01H71/16
Filed: 1977-04-30
Abstract: When appts. to be protected undergoes an abnormal temp. rise, the bimetallic strip moves upward until its arc is reversed, forcing up the dent (1') and therefore the contact arm (1) too. Consequently, the contact (2) is raised away from the clamp serving as the mating contact while at the same time, the inverted U-shaped free end (6') of the reset arm (6) is forced, by virtue of the arm's own elasticity, into the space now left open under the contact arm (1). Thus, even after the bimetallic element has returned to the original position, the contact arm (1) is kept from descending by the reset arm (6) and hence the contact (2) remains in the off position. When resetting the operator pulls out the free end (6') of the reset arm (6) from the space below the contact arm (1) with tweezers or the like.
