Abstract: In contrast to existing light addressed light valves for projection displays which use a homogene­ous CdS or Se photoconductive layer as the control element for a liquid crystal cell, a silicon photo-diode array is disclosed which makes an effective control element capable of applying a spatially varying AC voltage across a liquid crystal light valve. Writing may be done with a mini­ature CRT in an optical or electron excitation mode. It is shown that for a video mode the ratio of diode capacitance to liquid crystal cell capacitance with the diode, and the frequency of the applied square wave voltage, define the buildup or decay time of the liquid crystal cell voltage. thus, the frequency of the applied AC voltage can be used to control sensitivity and transient response and there is no lag. The dynamic range of the cell voltage is shown to depend on the ratio of diode capacitance to liquid crystal cell capacitance. The display can be used in a storage mode by erasing with an AC voltage and writing with a constant voltage. The silicon photodiode array is compatible with a CCD frame store using direct minority carrier injection for writing. This light addressed version thus represents a desirable milestone in achieving an all solid-state projection display.

Abstract: A side dam consisting of elements is arranged laterally of the casting nozzle and the casting mold. The side dam with the elements travels over two pulleys. Each element consists of a carrier and an easily exchangeable block which is connected to the carrier. Each carrier is supported at one end on a guide rail and a pulley by way of a foot and is swivel mounted at the other end to the foot of the neighboring element by way of a connection rod. By these measures optimum conditions are provided so that the side dam travels at a constant speed, despite the application of relatively long elements. Defect blocks can be exchanged during operation. The side dam's plane of motion is parallel to the mold wall's planes of motion and the side dam can herewith be adjusted at any desired depth between the casting mold walls, whereby the width of the cast product is determined.

Abstract: The present invention utilizes back lighting optics to produce converging white light over an area larger than an area of the edge of the convex object being profiled by the present invention. Opposite the back lighting optics are located a shadow image detector which detects the shadow image of the edge of the convex object, which is located between the back lighting optics and the shadow image detector. The detector generates a plurality of pixel outputs from each of a plurality of vertical locations for the shadow image of the edge. A rotating stage provides relative movement between the convex object and the detector/optics arrangement. The output of the detector which is a high resolution camera is fed into a data processing system which determines a sub-pixel distance measurement for each of the plurality of vertical locations and arranges the sub-pixel distance measurements into rows and columns to construct a surface profile of the convex object.
