Abstract: METHOD OF COMPREHENSIVE DISTORTION CORRECTION FOR         A COMPUTER  IMAGE GENERATION SYSTEM             ABSTRACT A method for computer image generation producing simulated visual scenes for applications such as flight training, employing a comprehensive distortion corection to generate the image takes place in three sequential stages:  Controller, Geometry Processor, and Display Processor.  The Display Processor generates video to produce the desired scene on the raster of the display device.  This scene is either projected onto a screen or viewed through collimating optices.  If the scene is projected through a wide-angle lens and/or is projected onto a curved screen, the combination of optical and geometric distortion presents a highly distorted scene to the viewer.  The comprehensive distortion correction method produces a precisely predistorted scene on the projector raster so it appears valid to the viewer. Mapping between projector space and viewer space is highly nonlinear.  However, a small region of the display (span) is selected sufficiently small so that the projector/viewer transformation may be considered linear.  The Geometry Processor defines face edges in viewer space and maps edge vertices into projector space.  In the Display Processor detection of spans intersected by a given face is done in viewer space using the mapped span corners and edge coefficients defined by the Geometry Processor.  Edge to span corner distances are determined in viewer space. These distances are used in projector space to determine a separate edge definition for each span.  This produces a piecewise linear approximation to the curves which exact mapping would provide.  The edges are continuous at span boundaries and have slope discontinuities so small as to be imperceptable.  The resulting scene appears fully valid to the viewer, with all distortions corrected.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for handling empty two-piece capsules includes a vertically reciprocating feeder which extracts capsules from a hopper and forms randomly ordered linear arrays.  A horizontal row of capsules are fed by the feeder to key-shaped slots in a block below the feeder.  A blade reciprocally positioned adjacent the wider portion of the key-shaped slots moves into the slot at about the middle of the capsule to turn the capsules so as to be partly positioned within the narrower portion of the key-shaped slot.  Each capsule is then ejected by projectable pins into a channel where the capsules are pneumatically accelerated into a pair of mated receiving rings which separate the two halves of the capsule.

Abstract: ABSTRACT OF THE INVENTION         Apparatus for cleaning the central opening or bore of a vehicle wheel and an adjacent annular radial surface includes a power driven shaft mounted for rotation about and axial movement along a fixed vertical axis. A cleaning head includes a horizontal plate axially slidable upon and rotatively fixed to the upper end of the shaft.  A horizontal cleaning disc is mounted upon the plate by a pair of parallel links, one of which is pivotally coupled to the upper end of the shaft to cause the disc to shift horizontally relative to the plate upon vertical movement of the disc relative to the plate and shaft.  Upon upward movement of the disc into engagement with a downwardly facing radial surface of a wheel centered over the shaft in a horizontal position, further upward movement of the shaft will shift the disc horizontally until a vertical cleaning surface on the disc engages the bore of the wheel.  Rotation of the cleaning head will clean the wheel surfaces of the wheel engaged by the disc and vertical surface.         The linkage arrangement enables the head to self adjust to wheels of different dimensions and cross-sectional configuration which may be fed in random sequence into the apparatus.

Abstract: A method and apparatus are described for adjusting clock pulses of time-equidistant digital line scanning values of a moving-image signal present in a composite color video signal to a clock used in a digital transmission link by means of a moving-image coder. In the transmitting part (10) of the moving-image coder, self-identifying stuffing characters are inserted into the string of image scanning values if clock deviations are found. The identification may be carried out by means of an additional bit or, alternatively, by a special code word when this is first removed from the supply of image scanning values. In the receiving part (30) of the moving-image coder, the stuffing character is recognized and removed and the original character string is restored.

Abstract: A small stream of the absorbent material is exposed to the gas stream whose concentration of the given component one wishes to determine. In the resulting absorption process, heat is liberated, and the absorbent stream thereby takes on an excess temperature in relation to the surrounding gas stream. This excess temperature is a measure of the concentration of the absorbed component. The temperature of the absorbent stream is adjusted prior to the contact with the gas stream, so that the entire quantity of heat that is liberated in the absorption process is put out to the surrounding gas stream by convection. The method achieves an accurate, continuous determination of concentration, not sensitive to variations in temperature and pressure or to changes in the gas speed past the measuring site and in the size of the absorbent stream. Furthermore, the method is not sensitive to the presence of dust in the gas mixture. The method can be used to determine the concentration of gaseous, absorbable components such as H2O, SO2, HCl, H2S, NH3, CO and CO2.

Abstract: A method for detoxifying a storage site for hazardous waste material, at which site the hazardous waste material is distributed at random, without contaminating the surrounding atmosphere, comprises the following steps: a casing delimiting an enclosed space is brought to a first station at the waste site; a zone A of stirred particulate waste is formed below the casing X; the zone A is heated to convert volatile toxic compounds to toxic vapours which flow upwards into the casing X together with free toxic gases; a toxic flow is led off from the casing X; toxic components are removed from the toxic flow and the air obtained is circulated back to the zone A; the type of toxic components remaining in zone A is determined; an oxidizing agent is introduced into zone A in order to render toxic metal salts essentially insoluble in water and tending to convert the remaining toxic organic components in zone A to volatile toxic waste; a dewatering agent is introduced into zone A to make the contents therein essentially impermeable to water; and the method is repeated at a second adjacent station. <IMAGE>

Abstract: The intention is to develop a method for producing cuts from an elastic paper, preferably a crêpe paper, by means of which it is possible for cuts to be made from two superposed paper webs (14) in common rotary slitting rollers (17) in a cost-effective manner and avoiding web-tensioning problems. 
<??>For this purpose, it is envisaged firstly to take all the paper webs (14) off a common parent roll (12), to form the individual paper webs by longitudinal cutting of the parent-roll web (12), and then to bring the said webs together and to cut them in an alternate manner from the two sides of the superposed paper webs (14) in the rotary slitting rollers (17). 
<??>As a result of the alternate cutting in the rotary slitting rollers (17), web-tensioning problems are avoided in the individual paper webs (14). The use of a parent roll (12) is, in terms of manufacture, advantageous compared with the use of corresponding single rolls.
