Abstract: A grow system is disclosed herein. The grow system can include a grow device that can include a light system including a plurality of light sources, a light position controller, and a processor. The processor can receive information relating to a plant to be grown by the grow system and can, based on that information, identify an operation program that specifies lighting and positioning of the illumination system. Using the operation program, the processor can generate one or several control signals to control the operation of the light system and the light position system.

Abstract: A reflective liquid crystal light valve projection system employs a polarizing beam splitter (16) to reflect light from a high intensity arc lamp (10) to a liquid crystal light valve (34) that is controlled by an image generator (36). Light reflected from the liquid crystal light valve is transmitted through the polarizing beam splitter (16) to a projection lens (38) and projected on a screen. Ghost images of the arc lamp source and diminished contrast are caused by light reflected from surfaces of the lens elements back to the liquid crystal light valve and then retroreflected back through the lens. The ghost images and diminished contrast are eliminated by interposing a broad band quarter wave plate between the lens and the polarizing beam splitter.

Abstract: In apparatus for charging and discharging substrates, substrates are disposed in a magazine or substance store and into the pre-chamber of a high-vacuum-processing-chamber which is made as a vacuum chamber, the magazine being pushed into a housing, which at its lower side provides an opening. The housing can be deposited with the magazine onto the upper part of the wall of the lower box, an air lock plate held below an opening in the upper part of the wall taking the magazine and lowering it into a lower position by means of a pair of lifting cylinders. After this the air lock plate with the magazine and the pair of lifting cylinders are movable laterally on a conveying-slide-carriage, until the air lock plate is positioned below the passage of opening in the bottom part of the vacuum chamber. Eventually the air lock plate can be moved so far up in a vertical direction, until the magazine is disposed in the pre-chamber and until the air lock plate, which is a little bigger, closes the opening of passage.
