Abstract: ABSTRACT OF THE DISCLOSURE   A drilling device includes a frame with a stationary and a movable upright and a transverse beam which connects said uprights with each other along which a drilling unit moves transversely to the advance direction of the workpiece and is set to provide boreholes in accordance to the center of a standard workpiece of nominal height.  The workpiece is transported by a roller table and clamped by the movable upright to define a clamping path.  Connected to the movable upright is a lever assembly which transmits the horizontal movement of this upright to a vertical bar.  The displacement of the vertical bar rotates a horizontal rod which is linked via a crank arm/lever assembly to a transmission bar moved in horizontal direction upon rotation of the rod. The transmission bar is connected to a correction unit which in response to the determination of the clamping path acts on the drilling unit to adjust the latter in dependence on the actual height of the workpiece.

Abstract: A METHOD OF MAKING A COMPATIBLE PITCH FROM COAL TAR, AND/OR PETROLEUM TAR, AND PITCHES THEREOF.                       ABSTRACT    A method of making a compatible pitch by refluxing for several hours in the presence of a Lewis acid catalyst, a feed consisting at least one member selected from coal tar distillate fractions, and petroleum tar distillate fractions having at least 50% of the carbon atoms in aromatic rings, each fraction having a boiling point of at least 330°C, while blowing air into said feed to produce a compatible pitch.  The pitch has (Q.I.) content of less than 4%, a sulphur content less than 2%, a carbon to hydrogen ratio of at least 1.65:1.  Surprisingly enough in general these pitches are compatible with one another and the new pitch obtained solely from a petroleum distillate in accordance with the invention may be blended with a new pitch obtained solely from a coal tar distil-late also obtained according to the invention, or with a pitch derived from distillates of coal tar and petroleum.          These new pitches have also other unusual characteristics.

Abstract: Abstract of the Disclosure The disclosure relates to an apparatus and method for forming a scanning electron beam for use in a flat screen cathode ray tube device.  An analog addressing method enables scanning of one axis of the screen of the CRT device. During scanning, all portions of a sheet of electrons emitted by a line cathode are deflected at any given time and blocked by an analog horizontal-positioning deflection grid except for one narrow portion disposed along the length of the line cathode.  At the one portion, a narrow beam of electrons is formed.  The grid contains an address plate and a load plate.  The load plate creates a voltage gradient causing each location along its horizontal axis to be at a distinct voltage.  Horizontal scanning is accomplished by applying a varying central voltage to the address plate.  This varying voltage will be matched by an equal voltage at a single predetermined location along the horizontal axis of the load plate adjacent to which electrons can pass undeflected in the form of a beam.  At all other locations along the horizontal axis, unequal voltages on the plates deflect electrons in the sheet passing between them and cause the electrons to be blocked.  Vertical scanning is accomplished by varying the voltage difference between two parallel vertical deflection plates between which the scanned electron beam passes.  The disclosure also relates to the use of electromagnetic rather than electrostatic deflections in producing a scanning electron beam from a line cathode.  In addition, the disclosure relates to multiple beams for scanning and producing of color images.

Abstract: ABSTRACT OF THE DISCLOSURE           A  semiconductor  laser  has  a  semiconductor substrate with a feature on its surface.  The feature, either a projection or a groove, forms a mesa or a mesa groove having relatively sharp edges.  Active layers and cladding  layers  are  deposited  on  this  semiconductor substrate.  The cladding layer deposited directly on the semiconductor substrate has at least one slope opposite the mesa or mesa groove, on which slope no active layer is formed during epitaxial  growth.   The active layer immediately above the cladding layer is prevented from depositing on the slope of the cladding layer so that no etching  process  for  removing  sections  of  the  active layer  is  necessary.    This  allows  deposition  of  the active layers and cladding layers on the semiconductor substrate  in  an  uninterrupted  sequence of  single epitaxial growth steps.

Abstract: ABSTRACT OF THE DISCLOSURE         A decision feedback equalizer has an adaptive filter responsive to a demodulated data sequence and a residual intersymbol interference (ISI) signal for estimating ISI which occurs during pulse transmission of a period of T seconds and producing an estimated ISI signal.  A subtractor subtracts the estimated ISI signal from a received signal which involves an ISI signal to produce a residual signal.  A circuit is provided for extracting the residual ISI signal from the residual signal and a delayed residual signal which is produced by delaying the residual signal.  A demodulator produces the demodulated data sequence from the residual signal and applies the data sequence to the filter.  A pattern detector detects a particular consecutive pattern out of the demodulated data sequence.  The residual ISI signal is applied to the filter in response to an output of the pattern detector.  The invention dispenses with the need for an automatic gain control circuit, thereby permitting scaling down the hardware.
