Abstract: A multiple color display system employing a high speed display panel adapted for positioning on a conventional photographic projector for displaying large video images. The high speed display panel is coupled to an interface unit for converting conventional NTSC signals into analog signals for driving a controller employing a modulation or duty cycle circuit coupled between the high speed display panel and a memory which is drive by the interface unit. The controller also employs a scan modulator for formatting the NTSC signal so that it may be displayed on a 640 by 480 matrix array employed by the high speed display device.

Abstract: A multiple color display system employing a display device having a plurality of pixel elements each having a set of three subpixel components and a interfacing unit to couple a television signal to the active matrix panel. The interfacing includes a color enhancing unit for defining composite pixel groupings in the active matrix panel and for causing each grouping to produce in excess of 185 thousand different color shading levels.

Abstract: Compounds of the general formula ##STR1## in which R.sup.1 and R.sup.2 each independently represents an alkyl group, Z represents a nitrogen atom or a group CH unsubstituted or substituted by a substituent X, m is 0 or an integer from 1 to 4, the or each Y represents a halogen atom, n is 0 or an integer from 1 to 5, and the or each X represents a halogen atom or a group selected from alkyl, haloalkyl, cyanoalkyl, alkenyl, alkynyl, alkoxy, alkenyloxy, alkynyloxy, alkylthio, alkenylthio, alkynylthio, cyano, nitro, alkylsulphonyl, alkylsulphinyl, and sulphonamido, have been found to have herbicidal activity.

Abstract: The display system includes a liquid crystal display panel unit having three different color components for each pixel of the resulting display. Each one of the individual color components of a pixel of the liquid crystal display panel unit is activated selectively by a corresponding one of a set of video processing units. Each video processing unit is responsive to a video signal from a conventional computer processor for causing the reproduction of a component of a colored image. Each video processing unit includes a translating arrangement for converting a component part of the computer generated video signal into a binary digital signal indicative of a single one of the color components for mixing with other color components to reproduce faithfully the computer generated color image.

Abstract: A hand-operated shower head is designed for mounting to the inner wall of a bathtub, with a squeeze pump for drawing water from the bathtub and forcing it up through a length of flexible tubing through a decorative shower head at the top. The device is useful for the amusement of a child while taking a bath.

Abstract: Apparatus and method for use with a flow packing machine for detecting and identifying the presence of metallic contaminants in bulk material loaded into a container is disclosed. The apparatus according to the invention includes a filler conduit for conducting the bulk material from the flow packing machine into the container. A metal detector senses the presence of metallic contaminants in the material being loaded into the container through the filter conduit and provides a detection signal indicative thereof. A spray gun or other marking device is supplied with an indelible fluid. The spray gun marks the exterior surface of the container in response to the detection signal.
