Abstract: Title: "Procedure for Aligning Sheets ABSTRACT          The invention refers to a procedure for aligning sheets as they are continuously conveyed via a feed table to a first uniformly rotating cylinder of a sheet processing machine. In a first feed stage, the sheets conveyed via the feed table in an imbricated arrangement are carried to an alignment area. Here, in a second feed stage, they are subject, in the imbricated position, to lateral alignment as well as preliminary front edge alignment without interrupting the movement in the conveying direction. Finally, in a third feed stage, the conveying speed of the sheets is accelerated from the stream speed to the peripheral speed of the cylinder and fed to the first uniformly rotating cylinder,  while being finally aligned at the front markers. The three-stage sheet feed system enables precise sheet feed without interrupting sheet transport at a printing speed which is higher than usual speeds at present.  The alignment method and equipment are simple and inexpensively priced.

Abstract: ABSTRACT OF THE DISCLOSURE         A support matrix for catalytically acting bonds, for example, for use in catalysts for the catalytic cracking of nitric oxides, is constructed from a metallic support, an inter-mediate layer of enamel adhesively applied to said support and a porous ceramic covering layer applied to the intermediate enamel layer.  The support matrix is produced by immersing the metallic support in an enamel slip followed by burning at 800 to 900°C.          The enameled metalic support is then immersed in a ceramic slip and said support is burned in a second burning step to the ceramic covering layer, which is the actual supporting layer for the catalytically active bonds.

Abstract: Abstract of the Disclosure Padding for a radiographic film packet may be formed of a foamed ethylene vinyl acetate and supplied as a portion of the film packet or as a pad for attachment to an existing film packet. The pad extends along an edge surface on the film packet to relieve discomfort and to facilitate positioning of the pad and film packet within the patient's mouth for accurate exposure to X-rays. The side of the packet opposite the pad is allowed to remain unpadded for the following reasons; to avoid increasing the overall packet dimensions, to facilitate relatively free access to the film contents of the packet, and to enable the film packet to fit into film holders that are currently used for film placement. The padded film packet is especially useful in periapical films where it is especially desirable to expose root areas and adjacent tissues.

This variability testing of and adaptation to the optimum parameter value for each head media combination and by grouping tracks in contiguous data bands, the parameters may be optimized for tracks near the inner diameter, the outer diameter and in the middle band.  The variable delta-V can also be used as an additional data recovery tool wherein re-reading with a lower value enhances recovery of missing bit errors and re-reading with an increased value can assist recovery from an extra bit error.

Abstract: "GROUND WORKING SWEEP"          ABSTRACT OF THE DISCLOSURE       A ground working sweep comprises a flange for supporting the sweep body and provides two cutting edges lying in a horizontal plane extending rearwardly and outwardly from a central point at the front of the sweep. The point lies forwardly and below the flange and the point and edges lie in a horizontal plane.  In comparison with the conventional sweep, a pair of wings are added at the rear ends of the cutting edges so as to provide an additional cutting edge having a sharp change of direction relative to the outward direction of the first cutting edge.  The outermost point of the cutting edge lies on an edge extending rearwardly from the cutting edge.  The change in direction in the cutting edge acts to cut weeds running back along the cutting edge and the wings reduce the tendency of wear to decrease the working width of the sweep.

Abstract: Abstract of the Disclosure A digital television receiver, having a line-locked clock, includes a partly digital, partly analog phase locked loop.  This phase locked loop regenerates two quadrature phase related subcarrier signals that are used to synchronously demodulate the chrominance signal components of the composite video signals into two color information signals.  The phase locked loop includes an analog voltage controlled oscillator which generates a signal that is independent of any frequency instability in the line locked clock signal.  An analog-to-digital converter digitizes this signal to provide one of the subcarrier signals.  This subcarrier signal is applied to a read-only memory to generate the second subcarrier signal. The two color information signals are obtained by multiplying the chrominance signals by the first and second subcarrier signals.  A phase comparator determines the phase of the vector sum of the two color information signals and compares this against a desired phase value to generate a phase difference signal.  The phase difference signal is filtered and applied to a digital-to-analog converter which provides the frequency control signal for the analog voltage controlled oscillator.  In a second embodiment of the invention, a tracking filter is inserted at the output port of the analog-to-digital converter to allow the quantization resolution of the analog-to-digital to be reduced without affecting the performance of the phase locked loop.

Abstract: Fluorocarbon esters where Rf is a C3 to 21 perfluoroalkyl; R is H or CH3; m is 0 to 10, n is 0, when m is 1 to 10 and n is 1 to 10 when m is 0; p is 0 to 10. The esters can be easily homo- or copolymerised with suitable comonomers. The esters and polymers are used for treating porous or fibrous materials to make them oil repellent. The OH side chain makes the polymers soluble in many organic solvents and this eses application and increases the number of uses. The polymers may be crosslinked through the active OH group to give oil- and water-repellent polymers.

Abstract: In a method of pressing flour or other vegetable material into briquettes or pellets and of the kind, in which the pressing equipment is supplied with steam from a steam source producing steam in a saturated state, the new feature consists in that the steam prior to being supplied to the pressing equipment is heated to form dry or superheated steam by using an electrical steam drier or superheater of the kind having between its inlet (1) and outlet (2) a heating chamber (3) provided with electrical heating elements (4, 5), through which heating chamber (3) the steam is conducted. In this manner, it is avoided that the pressing equipment is blocked or choked by "gooey" or sticky pressing material. The steam may be heated by means of an electrical steam drier and/or superheater with an inlet (1), a heating chamber (3) for saturated or wet steam and an outlet (2) for dried or superheated steam, in which the heating chamber (3) is elongated with the inlet (1) and the outlet (2) placed at the same end (7), from which a partition wall (8) extends to a location at a distance from the opposite end (10) of the heating chamber (3), whereas both the partition wall (8) and the electrical heating elements (4, 5) are secured to a removable cover (9), on its outside (in a housing 6) carrying the requisite electrical connecting means for the heating elements (4, 5). This makes it possible to clean and/or inspect the apparatus with a minimum of effort, as both the partition wall (8) and the heating element (4, 5) can be removed simultaneously by removing the removable cover (9). With the vertical orientation of the heating chamber (3) shown it is additionally achieved that the mechanical loading on the partition wall (8) and the heating elements (4, 5) is as little as possible, and that any water will collect below in the heating chamber (3), from where it is drained automatically through a steam trap (13). <IMAGE>
