Abstract: Abstract of the Disclosure In a method wherein two or more separate zones in a single wellbore are subjected to a consolidation treatment to prevent the production of solid particles from those zones into the wellbore, a tracer material is incorporated into each zone which is subjected to the consolidating treatment, the tracer material being unique to that particular zone.  There-after, fluid produced from the well is analyzed to determine if any and, if so, which zone or zones are still leaking solid particles into the well. Subsequent consolidation retreatment of the well is then limited to the zone or zones indicated to be leaking solid particles rather than being applied to all zones in the well again.

Abstract: TITLE OPTICAL COUPLERS FOR FIBER OPTIC       COMMUNICATION LINKS                          INVENTORS                    Brian S. Kawasaki Derwyn C. Johnson ABSTRACT OF THE DISCLOSURE         An optical coupler for a multi-mode optical fiber transmission line consisting of a first length of optical fiber and a second length of optical fiber posi-tioned along a common axis such that one end of the second fiber is spaced a predetermined distance ? from one end of the first fiber.  This allows a portion of the optical energy leaving the end of first fiber to enter the second fiber.  The coupler further includes a reflective surface facing the first fiber to reflect the remaining portion of the optical energy out of the coupler.  The percentage of the energy reflected out of the coupler is determined by the distance ? and may be varied by moving the second fiber with respect to the first.  The material between the ends of the fibers has a refractive index substantially identical to the refractive index of the fiber cores to provide for greater efficiency.  A second reflective sur-face means facing the end of the second fiber may be uti-lized to reflect and focus optical energy entering the coupler, into the end of the second fiber.  The reflective surfaces may be planar, parabolic, spherical, ellipsoidal or any other appropriate shape.

Abstract: J. F. O'Neill 22 RESISTIVE BATTERY FEED FOR LINE CIRCUITS          Abstract of the Disclosure A line circuit, interconnecting a subscriber telephone line and a port circuit, includes shunt battery feed resistors of equal impedance together with resistors in series with the subscriber line and a further resistor connected to a point intermediate one battery feed resistor and the adjacent series line resistor.  Each series line resistor has an impedance value equal to half the impedance value of the further resistor and forms a pad configuration that provides longitudinal balance and bilateral impedance matching. Stability declines, created  . by the bidirectional gain of an active hybrid used to overcome the insertion loss of the pad, are offset by stability improvements created through a reduced sensitivity to impedance variations in the subscriber line. Numerous other advantages result from the use of this pad configuration such as a reduction in size, weight and cost.                             - i -

Abstract: TITLE:     PHOTOGRAPHIC TYPE COMPOSING MACHINE AND METHOD  INVENTOR:  LOUIS M. MOYROUD                      ABSTRACT OF THE DISCLOSURE        The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums.  The characters are located in arrays such as concentric rows on a disc.  A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage.  Character spacing is determined by motion of the lens carriage and/or the lamp carriage.  Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage.  Composition of lines or columns of characters taken from a relatively large number of different arrays, such as would be the case in type composition using Chinese ideographs, is speeded considerably by controlling the order in which the characters are projected so that the lens carriage need not reverse its direction of motion during composition of a line.  A simple mechanism is used to change lenses for size changes by the selective use of stops at the ends of the travel path of the lens carriage.  Two discs or drums can be used alternatingly to increase the number of characters available.  A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like.  This avoids the necessity of providing a separate headlining machine. Another simple attachment is provided for inserting Pi characters. This attachment makes use of the lamp carriage and drive mechanism in selecting the Pi characters for projection.  A method which is especially useful in economically producing large matrix discs is described.  An economical "floppy" or flexible  film disc also is described.  A system and method are described for electronically detecting base-line and spacing errors in the characters on the character matrix, storing the errors, and correcting the errors electronically during projection of the characters onto the photographic film.

Preferably the frequency of the scramble signal generator is selected to fall within the band of frequencies of the TV channel between the video carrier and the audio carrier.  The TV channel is transmitted to receivers encoded with the scramble signal carrier providing false and misleading information, preventing the receiver from reconstituting a coherent picture or sound while this scramble signal is present.  The transmitted signal is decoded, (i.e. scramble signal removed), restoring regular reception by filtering with a sharply tuned high-Q notch filter attached to the drop line going to a TV receiver.  By careful selection of the band width and attenuation of the filter and pre-emphasis of the channel band, degradation of the video information is prevented.

Abstract: NON-DESTRUCTIVE INTERROGATION CONTROL CIRCUIT FOR               A VARIABLE THRESHOLD FET MEMORY                    ABSTRACT OF THE DISCLOSURE   An illustrative embodiment of the invention provides a substantially non-destructive interrogation of a memory cell circuit comprising a P-channel variable threshold insulated gate field effect memory transistor device.  The memory cell circuit provides a fixed current for interrogation of the memory cell transistor such that the disturb voltage (the voltage im-pressed across the insulator of the memory transistor during interrogation) is minimized and is a function of the current and the gain of the memory cell device and not the threshold voltage of the memory device.  The disturb voltage is readily calculable and is maintained constant for all interrogations; thus, enabling one to calculate the maximum number of interrogations of the memory cell before the disturb voltage destroys the memory threshold of the memory cell.  Rewriting of the data in the memory cell is performed before the memory threshold is destroyed.          In addition, a sense latch circuit is provided for sensing the memory data of the memory cell without applying an additional disturb potential to the device.
