Abstract: ABSTRACT          A method of reducing DC components in a digital information signal comprised of a plurality of 8-bit data words by converting each of the 8-bit data words to a 10-bit data word, comprises the steps of grouping the 10-bit data words by weight in accordance with the run length of data of each of the, 10-bit data words, with the 10-bit data words only including five or six logic level "1" bits; assigning each of the 8-bit data words to   one of the 10-bit data words in accordance with the frequency of occurrence of the 8-bit data words so that 8-bit data words having a high frequency of occurrence are assigned to 10-bit data words having a short run length; classifying the grouped 10-bit data words into a first group consisting of 10-bit data words having five logic level "1" bits, a second group consisting of 10-bit data words having six logic level "1" bits, and a third group consisting of 10-bit data words having four logic level "1" bits, with the third group being formed by inverting the 10-bit words in the second group; and further assigning the 8-bit words alternately to the 10-bit words in the second and third groups when such 8-bit words correspond to previously-assigned 10-bit words having six logic level "1" bits and assigning the remaining 8-bit words to the 10-bit words in the first group.

Abstract: ABSTRACT OF THE DISCLOSURE           A torque converter is disclosed, wherein a high rotational speed input engine can drive an output shaft at a relatively low speed but with a much greater torque.  A vertical power shaft extends above and below a roof, radially extending and horizontally disposed power arms are secured to the shaft above the roof and are supported at their outer ends by the wheels riding on the roof.  Each tire wheel is driven by an input engine mounted on the power arm.  These arms can have, for instance, a length of 50' each.  The portion of the power shaft extending below the roof is connected to a load through a suitable transmission.  The engines mounted on the power arms rotate at a high speed, while the power shaft rotates at a very low speed, for instance at about 25 r.p.m.

Abstract: PLANETARY 'SZ' TWIST ACCUMULATORS            Abstract of the Disclosure An accumulator for twisting or stranding cable having planet gears revolving around a sun gear.  Each planet gear carries an accumulator roll in a position spaced from the planet gear axis so that during rotation of the gears each accumulator roll travels alternately towards and away from the axis of the sun gear.  The accumulator rolls move in synchronism and thus the accumulator capacity which is dictated by the distance between accumulator rolls, changes between maximum and minimum capacities dependent upon the accumulator roll movement.  With two accumulators in series and operating with the accumulator rolls of one accumulator out of phase with the other by 180°, an 'SZ' twist is provided.                             - i -

Abstract: Abstract The present invention is concerned with a process by means of which the fraction of grain flour that remains after separation of the main part of the starch in the grain flour, and possibly of the gluten-type protein, which remaining fraction contains 15 to 40 per cent by weight of the dry substance of the grain flour, depending on the species of grain, is divided into two products of food quality, one of these products comprising a 20 to 35 percent-by-weight fraction of the dry substance, consisting mainly of the albumm-globulin-type proteins soluble in water of the grain, and the other one, a syrupy product, consisting mainly of sugars obtained as products of hydro-lysis of small-particle starch of grain. By means of the process, grain flour can be fractioned into three, in the case of certain flour species, four, industrially usable products, which are ordinary grain starch, gluten in the case of certain grains species, syrup obtained from small-particle starch, and soluble proteins, so that no waste or waste waters are produced at all. According to the in-vention the homogenous slurry obtained after separation of ordinary grain starch and gluten from the grain flour by known methods and containing 15 to 40 per cent by weight of the dry substance of the grain flour, is heated at a temperature of at least 120°C, treated at a temperature of at the most 90°C simultaneously by means of alpha-amylase and beta-glucanase, the produced precipitate, containing at least 40 per cent by weight of protein, as calculated from the dry substance of the precipitate, is separated from the sludge, washed, and dried, the remaining clear fraction is sugared by means of amyloglucosidase or fun-galamylase at a temperature of at the most 55°C until the dextrose equivalent (De) of the sludge is at least 20, and the syrup obtained is, if necessary, concentrated by eva-porating water.

Abstract: ABSTRACT OF THE DISCLOSURE         A video image compensator for inspection apparatus is presented for utilization in a system of the type in which an image of a workpiece is digi-tized and compared against stored data representing a workpiece of known acceptable quality.  The inven-tion compensates for instability, drift, and distor-tion inherently present in vidicons by providing a test pattern for periodic viewing by the vidicon, and providing therefrom data from which scale factors and image shift data can be generated.  Subsequent live images of workpieces can then be scaled and shifted prior to correlation with the stored refer-ence to compensate for instability, drift, and dis-tortion of the vidicon.  A mirror is used to alter-nately direct the field of view of the vidicon to either the test pattern or the workpiece target. In one embodiment, the mirror is made selectively transparent to allow the workpiece to be viewed, while in an alternate embodiment, the mirror is phy-sically deflected from the vidicon's field of view.
