Date Oct. 28, 1982.A control system is coupled to control a system for spatially transforming images by separate transformation of each dimension of the image. The control system includes a control panel having a three-axis joystick and a set of keys providing function selection and assignment of the joystick to a particular control function, a panel processor coupled to receive and interpret control panel data and a high level controller. The high level controller responds to the operator control information from the panel processor to establish selected image transformation information at selected knot points and communicates to a transformation portion of the transformation system data controlling the transformation of each image field with data for fields between knot points being developed from a cubic spline interpolation between knot points.

Abstract: This invention relates to the gasification of coal. An oxygen jet having a pointed flame is engendered in situ, so as to strike the coal with a sheath of steam. The resultant fuel gas is drawn off while flowing in counterflow with the jet of oxygen and is brought to the surface through the same bore which had served the purpose of supplying oxygen. The invention is particularly applicable to the underground gasification of coal in situ.

Abstract: A process for the continuous foaming of plastics, especially polyurethane, of the type in which the foaming space is delimited by flexible material bands which are fed together with the bun of foamed material being formed. As flexible material for these bands a composite web is used which comprises a support paper band and a thin impermeable band of plastics, preferably polyethylene having a thickness from 5 to 40 microns. The two bands of which the flexible is composed have a reduced adhesion to one another. The paper band is then detached from the bun of foamed material by disengaging it from the band of plastics which is left permanently adherent to the foamed material or is detached from this latter in an operation subsequent to the detachment of the paper band. In this way, losses of material are avoided, and the paper of the paper bands can be recovered.

Abstract: The present invention relates to a method for producing alkalimetal selenite and alkalimetal selenate from metallic selenium through selenous acid. The selenium is dissolved in nitric acid to form selenous acid, which is reacted with an alkalimetal base, to form alkalimetal selenite. The formed selenite is then spray dried. Alternatively, the formed selenite is oxidized at elevated temperature in a basic environment at pH 10-12, with hydrogen peroxide as the oxidant, to form selenate, which is then spray dried.The invention also relates to products produced by the method. The products are intended to be incorporated in animal-fodder or foodstuffs (selenite), or in fertilizers (selenate), to be thus administered to human beings and animals as trace substances.

Abstract: High efficiency apparatus for coding digital video data in which the number of bits per picture element in the video data such as a digital video signal or the like is compressed. The video data of a television picture plane is divided into a number of three-dimensional blocks, i.e., spatial blocks. The picture element data in the block can be coded by the reduced number of bits by the bit compression by performing the coding process adapted to the narrowed dynamic range on the basis of the correlation among the picture elements in each block. The transmission data of the number of bits reduced as compared with the number of bits of the original data can be formed. By coding only the necessary frame by discriminating the movement of the image in the block, the redundancy in the direction of time can be removed.
