Abstract: ABSTRACT OF THE DISCLOSURE         A  method  of  forming  and  installing anti-vibration bars into a tube bundle of a steam genera-tor is disclosed.  The tube bundle comprises rows of tubes, each tube carrying a high temperature coolant. Each of the resultant anti-vibration bars has a tubular configuration and is disposed between adjacent rows of the tube bundle for stabilizing the tubes against vibration caused by fluids recirculating at high velocities through the steam generator.  The method of this invention com-prises the steps of inserting at least one anti-vibration bar between adjacent rows of the tube bundle and applying a pressurized fluid in the anti-vibration bar, thus ex-panding the anti-vibration bar to contact the tubes of the adjacent rows and to make a series of indentations there-in.  Typically, the pressure of the fluid is increased incrementally up to a maximum level set such that the con-figuration of the steam generator tubes is not deformed. The resultant anti-vibration bar is a hollow member and has first and second series of indentations disposed on opposing sides thereof and spaced from each other a uni-form distance corresponding to the spacing between adja-cent tubes of a row.  The indentations are configured sim-ilarly to the shape of the tubes to provide intimate contact there between and to support the tubes against vibration.

Abstract: ABSTRACT OF DISCLOSURE          The invention is directed to a process for the pro-duction of cationic binders for pigment pastes for water-dilutable paints, particularly for cathodic electrodeposition based on low molecular oxazolidine group carrying modified epoxy compounds, and to the pastes obtained.  The process is characterized in that preferably aliphatic di- or polyepoxy compounds are reacted with primary mono- and/or diamines and optionally monocarboxy compounds and that oxazolidine groups are introduced into the molecule by reaction with carbonyl compounds.  The products show extremely high pigment loading capacity and an excellent performance in cathodically deposi-table electrodeposition paints.  The products permit formation of low solvent paint systems.

Abstract: SYSTEM FOR OPTIMIZING THE TIMING OF   DIESEL OR SPARK IGNITION ENGINES             ABSTRACT OF THE DISCLOSURE        An adaptive electronic control system in which a machine control parameter is oscillated (dithered) back and forth on either side of a given setting of such machine control parameter, with the period of the dithering being in synchronism with the natural cycle of the machine, whereby the changes in the control system's error signal due to normal speed changes of the machine itself are minimized or eliminated. When applied to a spark ignition of a gasoline engine or the injection timing on a diesel engine, the timing is advanced and retarded in synchronism with the rotation of the engine's shaft such that each phase of the dither cycle includes an equal number of complete engine cycles. The effect on engine speed occasioned by the dithering of the machine control parameter is then computed and an error signal is produced which is used to further adjust the parameter control setting in a direction to optimize performance of the machine. The system may be implemented by using a properly programmed microprocessor or, alternatively, can be implemented with discrete digital logic components.

Abstract: On a measuring table (1), a bridge (2) extends over a printed sheet (5) to be measured. A measuring carriage (3) carrying a three color-simultaneous measuring head is arranged on the bridge (2) for linear movement in a back-and-forth manner along a desired path on the printed sheet. For control of the movement of the measuring head during measuring runs and for the evaluation of the measured data, a computer (7) with an integrated image display terminal and a processor system (6) controlled by the computer, is provided with the necessary interfaces. The analysis of a color measuring strip (MS) located along the desired path on the printed sheet is effected in two phases. In a first, so-called recognition run the measuring strip is scanned stepwise with high resolution in all three color channels, for the purpose of an analysis of its configuration. By means of flat locations in the density variations, effective positions (e.g., the centers) in the measuring fields are determined as possible measuring positions for subsequent measuring runs. During the measuring runs the measuring strip is measured only at the measuring positions determined during the recognition and the measured data obtained in this manner are transmitted for processing and/or display to the computer (7). By the division of the measurements into a recognition and a measuring run, coupled with the determination of measuring positions by means of flat locations in the density variations, a practically completely automatic evaluation of the color measuring strips independently of their configuration and without the need of prior knowledge of the strips by the apparatus, is rendered possible.

Abstract: A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity offluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface of said web using the dynamic and gravitational head of the fluid as a primary driving force. Each of the macroscopic cross-section capillary networks originates as an aperture in the first surface of the web and has a continuously interconnected sidewall extending in the direction of the second surface of said web. The continuously interconnected sidewall terminates to form at least one aperture in the second surface of said web, whereby the bulk of the dynamically deposited fluid is transmitted from the first surface to the second surface of said web by the macroscopic cross-section capillary networks. The first surface of the web in which the macroscopic cross-section capillary networks originate further includes a multiplicity of fluid-handling capillary networks which are substantially smaller in cross-section than the macroscopic cross-section fluid-handling capillary networks. The smaller fluid-handling capillary networks exhibit a degree of capillary suction sufficient to transmit static fluid contained on the surface of objectswhich contact the first surface of said web generally in the direction of the second surface of said web by capillary attraction. In a preferred embodiment the smaller fluid handling capillary networks are oppositely oriented from the macroscopic cross-section capillary networks to provide improved visual and tactile impression as well as to enhance the volume of dynamically deposited fluid which flows into the macroscopic cross-section capillary networks.
