Abstract: SYSTEM AND METHOD FOR RASTER-SCAN DISPLAY              ABSTRACT OF THE DISCLOSURE    In system and method for smooth line raster-scan display, a frame buffer containing a high resolution map of information of an image for display is read so as to furnish plural line stored information for each single line of the raster display.  Display circuitry of the system receives the plural line stored infor-mation and varyingly weights same to furnish such single line Z-axis information (intensity control) for an X-Y display matrix, such as a CRT display terminal. Means are included in the system for display of the entire frame buffer content on a first fractional basis, e.g., a two thousand line resolution buffer to five hundred line raster.  Selection circuitry of the system provides for reading out only a fraction of the frame buffer content, e.g., one-fourth or the five hundred lines thereof, on five hundred raster lines, thus providing true resolution zoom capability.

Abstract: ABSTRACT OF THE DISCLOSURE     A force transducer angularly adjustable about an axis for pro-ducing and output signal proportional to the magnitude of an input force.  A signal output member, cantilevered from a base through a spring flexure, is provided with a spindle, the center of which lies in the axis, receives the input force.  The moment impressed on the flexure by the input force and the resulting displacement of the output signal member from a null or no-load position is a function of the magnitude of the input force and the angular adjustment of the transducer about the axis.  Such angular adjustments can be made in-situ without disturbing the spatial position of the spindle.

A spandex spinneret having the holes of the orifices of each group of the outer ring of groupfs more closely spaced than those of the inner ring of groups has eliminated the power differences between inner and outer threadlines.  The closer spacing within each group of the outer ring of groups also increases the spacing between groups, thereby reducing filament migration.

Abstract: Abstract of the Disclosure For operations in the prone sitting position, the novel kneeling attachment has a lower-leg platform from which a pair of posts project downwardly to rest against the floor to support the lower portion of the patient's body while his or her upper body is moved up or down relative to the buttocks by vertically moving the operating table. After thus adjusting the attitude of the patient's backbone, the lower-leg platform is locked, the posts are retracted, and the operating table can be moved to whatever height is most comfortable to the surgeon. The lower-leg platform of the kneeling attachment includes cushioning which is formed with two longitudinal channels that conform to the lower legs of a patient. A spacing between the lower-leg platform and the foot of the operating table leaves the kneecaps substantially unsupported, so that the patient's weight primarily rests on the tibial plateaus. The kneeling attachment may include a buttocks support which comprises a U-shaped yoke, the crosspiece of which carries a seat pad and the arms of which carry elongated, generally cylindrical cushions. Each of these cushions is formed with an off-center bore so that rotation of the cushions accommodates patients of differing hip sizes.

Abstract: ABSTRACT    A fender (10) which is essentially U-shaped in cross section and which consists of elastomer material in its energy-absorbing part, is manufactured in planar configuration and folded to U-sectional shape on mounting. To make folding possible and to provide both an equali-sation of tensile stresses and an increase of the transfer of forces between the web (12) and the legs (13) of the U-shaped cross section, longitudinal slots (17) are formed on the inside of the U-shaped cross section at the transition between the web and the legs. The mouth edges of the slot are bevelled and form mutually abutting supporting surfaces (18) for said transfer of forces. At the bottom of the slot (19), a longitudinal open channel (21) has been left to equalise the tensile stress occurring in the fender material on folding.

Abstract: Abstract A Method of Determining the Density of Substrata.    A method for determining the density of substrata by means of a radiation source K comprising a collimator (1) and of a detector comprising a collimator  (3),  by which method the direction of radiation may optionally be changed in relation to the direction of detection, and the change of the detected signal may be measured. According to the invention the direction of radiation and the direction of detection are situated in substantially the same plane. By deducting the signal of the desirable depth of measurement from a somewhat greater depth of measurement substantially only the signal originating from singly scattered radiation is obtained, and as a result it will be possible to measure the density at greater depth than previously. On the basis of a spectrum analysis of the spectrum originating from the measurement,  the variation of the density with the depth could be obtained.
