Abstract: ABSTRACT            A system for performing wellbore telemetry operations wherein a communication link between a subsurface location in a well and the location substantially at the surface is established and maintained through electromagnetic coupling between two in-sulated electric conductors.  The first conductor is electrically coupled to a transmitter, normally located at the subsurface location, and extends upwardly in the well.  The second conductor is electrically coupled to a receiver, normally at the surface location, and extends down into the well.  Normally, the two con-ductors will overlap along a substantial portion of the lengths thereof.  As the well is drilled deeper and the drill string is lengthened, the transmitter and the first conductor follow the progression of the wellbore into the earth, thereby reducing the overlap between the first and second conductors.  When the two conductors cease to overlap, the second conductor may be leng-thened to re-establish the overlap.

Abstract: ABSTRACT OF THE DISCLOSURE         Open-loop means are described for controlling the output speed of a D.C. motor connected to selectively move a carriage-mounted print head across the width of a paper document in either a forward or a reverse direction.  Solid state switch means initially couples a first voltage source to the D.C. motor to rapidly accelerate the print head in a first direction.  As soon as the print head reaches the desired velocity, the first voltage source is decoupled from the motor and a second highly regulated source is coupled to the D.C. motor to maintain movement of the print head at the desired constant velocity.  The switch means is adapted to reverse the polarity of the voltage at the input terminals of the D.C. motor to rapidly decelerate the print head, accelerate the print head in the opposite direction and subsequently maintain the desired constant velocity of the print head as it moves the reverse direction.  Logic means detects the direction of carriage movement and connects the first voltage source to the D.C. motor for a time interval suffi-cient to bring the D.C. motor to the desired final constant speed in as short an acceleration interval as is practical. The second voltage source maintains the constant speed until the print head reaches the end of the line.  As the print head moves to the end of a line, the logic means reverses the connection polarity to the motor and reapplies the first voltage for substantially the same time interval initially required for acceleration, so as to rapidly decelerate and halt print head motion, or alternatively applies the opposite polarity first voltage level for twice said time interval to bring the motor up to constant speed in the reverse direction.   1.     in as short a time interval as is practical.   Additional means apply the increased acceleration voltage in the carriage return direction for a proportionally shorter time interval after less than a full line is printed, to reduce carriage return travel time without damage that might otherwise be caused by excessive acceleration thereof.

Abstract: Abstract of the Disclosure Vector processing in a computer is achieved by means of a plurality of vector registers, a plurality of independent fully segmented functional units, and means for controlling the operation of the vector registers.  Operations are performed on data from vector register to functional unit and back to vector register with minimal delay, rather than memory to functional unit and return to memory with its attendant much greater start up delays.  Data may be bulk transferred between memory and some vector registers while other vector registers are involved in vector processing with one or more functional units.  In vector processing elements of one or more vector registers are successively transmitted as operands to a functional unit at a rate of one per clock period, and results are transmitted from a functional unit to a receiving vector register at the same rate. In a chaining mode of operation, the elements in a result vector register become available for immediate and simultaneous transmission as operands to another functional unit.  In this mode, more than one result can be obtained per clock period.

Further, two horizontal magnetic pole piece plates which are long horizontally and short vertically are so disposed as to sandwich side beams near the outlets of the side electron guns in order to weaken vertical deflection magnetic fields acting on the side beams and to intensify vertical deflection magnetic fields acting on the central beam.

Abstract: ABSTRACT OF DISCLOSURE     A titanium trichloride catalyst complex is produced by reducing titanium tetrachloride with an organo-metal compound and then activating the resulting reduced solids by treatment with a chlorinated hydrocarbon and titanium tetrachloride in the presence of a Lewis base complexing agent.  The employment of the chlorinated hydrocarbon and titanium tetrachloride in the presence of the Lewis base complexing agent unexpectedly produces a synergistic effect whereby activating conditions, e.g., temperature, time and TiCl4 concentration can be employed resulting in a titanium trichloride complex having superior alpha-olefin polymerization properties as compared to titanium trichloride catalyst complexes obtained by treatment under the same conditions in the absence of either titanium tetrachloride or chlorinated hydrocarbon.  Moreover, expectedly high yields of activated catalyst can be recovered without loss of activity.

Abstract: CHROMA LEVEL STABILIZER               Abstract Of The Disclosure A chroma level control circuit for a television receiver is responsive to the average of selected portions of color difference signals to reduce deviations from a viewer-selected chroma level. The preferred chromal level is selected by the viewer and the automatic control circuit responds to amplitude variations in selected portions of the color difference signals to stabilize chroma level about the preferred level. A gating circuit is responsive to the demodulated color difference signals and selective of portions thereof, i.e. the positive portion of the R-Y signal, so that only selected hues are used to automatically control the chroma level by adjustment of the receiver's chroma gain controlled amplifier.          The circuit is also responsive to low brightness levels in the scene to temporize chroma level control during low brightness scenes. In addition, the chroma level control circuit is frequency selective, i.e. long duration highly saturated scenes, such as a bright red background, will not be fully responded to as an undesired phenomenon requiring lowering of chroma level.
