Abstract: STABILIZATION PROCESS FOR BIOLOGICAL CELLS      AND STABILIZED COMPOSITIONS THEREOF            ABSTRACT OF THE DISCLOSURE         Biological cell compositions are stabilized to preserve aldehyde functionality by formation of acetal, particularly cyclic acetal, primarily in order to prevent cell-to-cell crosslinking.  The stabilized biological cells are particularly useful as human blood particle analogs in reference reagents employed in electronic hematology testing instrumentation.       A process for preparing the acetal stabilized biological cells employs reaction of polyaldehyde-treated biological cells with alcohol, preferably including 1,2 dialcohol, under acidic conditions; thereafter, the resulting product     solution is adjusted to basic condition, stabilizing the acetal formation on the biological cells.

Abstract: A MILL RECIRCULATION SYSTEM ABSTRACT OF THE DISCLOSURE       A mill recirculation system (10, 40) that is operative for purposes of effecting the pulverization and firing of solid fuels, while yet possessing all of the desirable features of a direct fired system. The subject system (10, 40) includes pulverizer means (14, 48), classifier means (12, 44) and burner means (16, 68) as well as a preestablished fluid flow path by which the pulverizer means (14, 48) and the classifier means (12, 44) are interconnected in fluid flow relation with the burner means (16, 68). In accord with the mode of operation of the subject mill recirculation system (10, 40) a stream of solid fuel is made to flow along the fluid flow path such that the solid fuel is pulverized in the pulverizer means (14, 48), classified according to particle size in the classifier means (12, 44) and fired in the burner means (16, 68). Further, a stream of a suitable gaseous medium is made to flow along the flow path such that the gaseous medium is operative to cause the solid fuel to be conveyed therewith through the pulverizer means (14, 48) while being dried thereby and to be conveyed therewith from the pulverizer means (14, 48) to the classifier means (12, 44). At the classifier means (12, 44) a separation is had of the stream of the gaseous medium such that a portion of the gaseous medium is recirculated along with the oversize solid fuel particles back to the pulverizer means (14, 48) while the remainder of the gaseous medium is operative to convey the solid fuel particles that are of the desired size from the classifier means (12, 44) to the burner means (16, 68) for burning, i.e., firing, in the latter.

Abstract: ABSTRACT OF THE DISCLOSURE         Control circuit for use with an image pickup tube permits highlights of an image to be scanned appropriately by a scanning electron beam by increasing the beam current fed to the cathode of the image pickup tube and prevents unwanted oscillations typically found when such beam currents are increased.  The control circuit first determines whether the output from the image pickup tube exceeds a predetermined level and produces a control signal to be added to the normal beam current and also uses this control signal to control a vertical deflection circuit to shift the scanning electron beam upwardly toward a region on the photoelectric transducer of the image pickup tube that has already been scanned, thereby providing negative feedback and preventing unacceptable oscillations in the output signal.

Abstract: Abstract of the Disclosure The inventive CRT is similar in structure to prior art CRT's except for the color-selection structure, which, as in the prior CRT's, produces a plurality of lenses for passing and focusing portions of electron beams to associated color groups of the target.  In the inventive CRT, the color-selection structure comprises at least one lenticular member having therein an array of windows associated with only one color group, each window having a half-width, r, and a conductive mesh having interstitial dimensions small compared to the phosphor elements in the color groups.  The lenticular member is longitudinally spaced a distance, s, from the conductive mesh so that the ratio of the longitudinal spacing, s, to the half-width, r, of the window is much less than unity (s/r << 1), whereby the lenticular member and the conductive mesh provide a strong lens action.

Abstract: Abstract of the Disclosure A closed loop register control system used in association with a printing press and comprising a television camera in combination with a strobe light and a solid state imaging device which enables continuous scanning of the sheet web.  The apparatus of this invention also comprises a printing press console having associated therewith a digitizing tablet and a television monitor.  The location of the area that is to be examined is defined by the pressman.  The area to be examined may be selected by laying a proof sheet down on the digitizing tablet and recording the coordinates of the area of interest.          This controls the camera and strobe light with the pressman selecting one part of the image as important and causing the register mechanism to maintain register in that selected area.          Electronics then make comparisons between the detected image and a desired reference image to cause correction on a per color basis at the printing press stations.

In a preferred embodiment, the film forming structure comprises a stacked laminate of initially imperforate planar sheets having continuous patterns of apertures therein and at least one initially perforate selectively apertured planar sheet located beneath the uppermost continuously apertured sheet.  The laminate forming structure is preferably tubular in shape so as to facilitate contin-uous plastic web processing against its outermost surface.  Film to be debossed and selectively aper-tured is brought in contacting relation with the laminate structure and subjected to a fluid pressure differential on said forming structure while at a temperature above its softening temperature.  The fluid pressure causes the heated plastic film to be debossed in those areas where said initially perforate selectively apertured lamina contacts the film and debossed and apertured in those areas where said initially perforate selectively apertured lamina does not contact the film.  The debossed and selectively apertured film is thereafter cooled below its softening temperature before removal from the forming structure.

Abstract: Apparatus and Method for Providing a Transparent Interface Across a Satellite Communications Link Abstract A mechanism is disclosed for a time division multiple access communications network, to enable the synchronizing of traffic messages between a transmitting and a receiving node.  A transmit clock mechanism at the transmitting node includes a slip counter for accumulating a slip count value during consecutive intervals of transmission.  The slip count value is transmitted along with the traffic messages over the communications link to the receiving node.  A slip count detector is located at the receiving node, for receiving the slip count value and adjusting the receive clock at the receiving node in response to the slip count value.  In this manner, a timing slip adjustment which has been made at the transmitting node will have a corresponding timing slip adjustment imposed at the receiving node so as to maintain the proper synchronization between the sending and receiving stations during a time division multiple access communications session.
