Abstract: DOCUMENT AUTOMATION PAGINATION                      Abstract The specification discloses a method for automatically paginating a data stream in a word processing system.  A vertical tracking register is incremented by a value representing the displacement of the vertical print position when a line end code is encountered.  The page overflow latch is then interrogated to determine whether a page overflow condition has occurred.  If a page overflow condition has occurred, the next character in the data stream following a line end code is interrogated to determine whether the character is a graphic character.  If the character is a graphic character, a page end code is copied into the output buffer ahead of the graphic character, the page overflow latch is reset and the tracking register is initialized.  The tracking register value is then interrogated to determine whether it exceeds the last typing line.  If the last typing line value has been exceeded, the page overflow latch is set.  The page overflow latch is subsequently interrogated to determine whether a page overflow condition exists.  If not, the input character is copied from the input buffer to the output buffer.

Abstract: TITLE                METHOD OF CONTROLLING A SOLAR                   SYSTEM COLLECTOR LOOP     INVENTOR                      Thomas Onno ABSTRACT OF THE DISCLOSURE        In a solar system collector loop, having a solar collector with an absorber plate, a heat storage unit and a pump for circulating a fluid between the collector and the storage unit, the stagnation temperature TQ of the collector absorber plate, the temperature TC of the collector absorber plate, and the storage temperature TS in the storage unit are measured.  The stagnation temperature is measured by a heat flux transducer based on a small sample of the absorbed plate which is thermally isolated from the collector but in the same enclos-ure.  This transducer generates temperatures near the stagnation condi-tion for the instantaneous operating point.  In the method of control, the pump is turned on when the temperature difference between the absorber plate TC or TQ and the storage TS, is greater than a predeter-mined value Ton.  The pump is turned off when the temperature differ-ence between the stagnation temperature TQ and collector absorber plate TC is smaller than a predetermined value Toff.  The temperature signals TQ, TC and TS may also be used to control obvious abnormalities in the system as well as fast radiation changes such as those caused by small clouds.

Abstract: ROTARY PRESSURE SEAL STRUCTURE AND METHOD FOR REDUCING THERMAL         STRESSES THEREIN ABSTRACT OF THE DISCLOSURE       A rotary member for restricting the flow of high temperature gas from a first cavity, intermediate rotating and stationary members of a gas turbine engine, and a second cavity, includes a central disc bore segment having an inner circumference and an outer circumferential seal segment. A closed cavity is formed by a portion of the rotating member and a portion of the rotating seal disc, with the inner circumference of the central disc bore segment positioned in a predetermined spaced relation with respect to the rotating member, forming a gap there-between. The closed cavity contains at least one aperture adjacent the outer circumferential seal segment. A portion of the high temperature gas flows through the aperture into the closed cavity, then exits the closed cavity through the gap formed between the inner circumference of the central disc bore segment and the rotating member. The gap in effect presents a constriction which causes a concomitant increase in the velocity of the gas through the gap. The high temperature gas, flowing at a relating high velocity across the inner circumference of the central disc bore segment reduces the temperature differential between the inner circumference and the outer circumferential seal segment thereby reducing thermal stresses in the rotary seal.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for screwing together pipes provided for the casing of a borehole.  The apparatus comprises a screwing-clamp device and a counter device which engage respective ones of two pipes to be screwed together.  The screwing-clamp device and counter device are carried on a common support structure by  means of a mounting arrangement which includes compensation elements for enabling relative displacement of the two devices during screwing together of two pipes.  Such relative displacement is required both due to the axial movement of the pipes during this process and due to eccentricities unavoidably present in the overall set up.  The compensation elements used to compensate for axial movement of the pipes take the form of hydraulic operating cylinders.  Preferably these cylinders are used to adjust the height of a support plate carrying the screwing-clamp device.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for applying newsprint ink and dampening fluid to a lithographic printing plate, the apparatus comprising an ink metering roller in rolling pressure indented relation with a transfer roller having an oleophillic surface and a dampening fluid transfer roller having a hydrophillic surface each of the transfer rollers being driven by a reversible variable speed motor.  The transfer rollers are in pressure indented relationship with a form roller which transfers a thin film of ink and dampening fluid to the printing plate.          An excess of ink is supplied to the nip between the metering roller and the transfer roller to produce the thin film of ink which may be further conditioned by an ink storage roller prior to entry of the film of ink into the ink transfer nip between the transfer roller and the form roller.  By controlling the relative speeds between the form roller and the transfer roller, slippage occurs which meters a thin film of ink onto the form roller for transfer and application to the printing plate.
