Abstract: Method for the production of a control system for a heating installation with a burner, and a control system arranged for using said method comprising the production of a central processing unit with a micro­computer and a memory for storing therein a control program to be processed by the microcomputer and containing instructions for receiving measurement signals originating from sensors and instructions for controlling actuators of the heating installation depending on the values of the measurement signals, the instructions containing parameters, in which after the production of the physical control system and the storing of the program in the memory, a group of values of variable parameters dependent on the use of the control system is stored from outside the control system in a rewritable section of the memory. Preferably a variable parameter is assigned to each group of variable parameters, said parameter having a value assigned exclusively to the group, and, after installation of the control system in a heating installation and after entering the variable parameter values into the memory, the program detects the type of this heating installation and compares a value corresponding to the detected type with the stored value of the parameter assigned exclusively to the group of variable parameters and gives an error signal if parity is not found.

Abstract: A method for determining the coordinates of stars for preparation of a star catalogue provides for recording the coordinates of the stars by means of an astrometric instrument rigidly installed at a desired angle to the longitudinal axis of a space apparatus rotating at a permanent speed about said axis which is oriented towards the sun, while the apparatus is passively stabilized by using sunlight pressure and the dissipation of energy in a viscous liquid. The measurement of star coordinates is repeated several times while recording the time moments of the measurements and then the results are processed for determination of the catalogue values of star coordinates.

Abstract: A print inspection method in which an area of printed material is optically scanned to obtain image data representing picture elements having variable intensity levels includes counting the number of picture elements at a particular intensity level in the area scanned to thereby generate a frequency distribution of the intensity level of the image data in the area scanned. The frequency distribution generated is compared to a stored reference frequency distribution of intensity levels of the image data. A statistical comparison with the reference data is utilized to determine whether or not the printed material is satisfactory.

Abstract: The invention relates to a plunger-type cylinder on whose cylinder jacket (30) a hydraulic signal pick-up nozzle (34) is arranged. The signal pick-up nozzle (34) is connected to the interior of the cylinder via a transverse bore (40). Located on the cylinder inside of the transverse bore (40) is an annular passage (42) which is defined at its opening-side and base-side flanks by guide and sealing rings (60, 62). The sealing ring (62) defining the base-side flank is designed as an open metal ring which is arranged in an annular cylinder recess (50) backing an elastomeric sealing ring (63). The plunger (16) has several control bores (28) which communicate with the base side of the inner space of the cylinder, pass through the plunger skirt (22) at a distance from the base-side plunger end (26) and trigger a control operation via the signal pick-up when crossing over the annular passage (42). <IMAGE>

Abstract: A water quality checker comprising a sensor member body (6) provided with a plurality of kinds of measuring sensors (7, 8, 9, 10) including at least a dissolved oxygen-measuring sensor (10) at one end portion thereof and a calibration container (5) for housing a standard solution (12) used for calibrating said measuring sensors is characterized by the fact that the dissolved oxygen-measuring sensor can be kept separated from said other measuring sensors intruding into the standard solution (12). The measuring sensors can be calibrated simultaneously due to the fact that the dissolved oxygen-measuring sensor (10) is exposed to air as a standard calibration gas. 
     Compared to conventional water quality checkers, the construction is considerably simplified by dispensing with a specific stirrer required so far for dissolving a sufficient amount of oxygen into the standard solution (12) during calibration of the dissolved oxygen-measuring sensor (10).

Abstract: A process for the production of needle-grade coke having a low coefficient of thermal expansion (CTE) value involves coking a petroleum feedstock in a coking drum at temperature below the threshold temperature where CTE values for the coke rapidly increase for a time sufficient to obtain a relatively low CTE coke. The petroleum feedstock can be decanted oil or heavy cycle oil. The threshold temperature can be from about 400°C to 600°C. A heated vapor stream is introduced into the drum to maintain the coke at a temperature sufficient for coking but below the threshold temperature.

In this disk, a collar (16) is inserted through the disk hub (10) and the friction plate (14) to be fixed to the disk hub (10) with a connecting bolt (17) piercing through the collar (16) and a nut (18) to mesh with the connecting bolt (16). A diametrally large stepped part (16a) is provided at the approximate center of the outer periphery of the collar (16) so as to form a gap between the disk hub (10) and the friction plate (14). One side surface (16b) of the diametrally large stepped part (16a) and the head (17a) of the connecting bolt (17) clamp the friction plate (14). The length of a shaft (16e) projecting from the other side surface (16d) of the diametrally large part (16a) is formed larger than the thickness of the disk hub (10). Such a structure as above can accommodate variation in thickness of the friction plate (14) due to thermal expansion and deformation of the braking surface of the friction plate (14) is prevented, causing no change in braking action.

Filed: 1991-03-07
Abstract: An apparatus for providing longitudinal, laterally spaced slits in a continuously moving sheet or web of corrugated paperboard (13) or the like includes a plurality of upper tool heads (12) each supporting a thin, circular rotary slitting blade (25). The blades (25) are coaxially mounted and driven by a common drive shaft (23) and each blade-carrying tool head (12) is independently positionable across the width of the paperboard sheet (13). Each slitting assembly includes a lower tool head or counterhead (28) carrying a roller assembly (32) which supports the underside (27) of the moving board (13) and provides a firm surface to support the board (13) against the upper rotary slitting blade (25). The roller assembly (32) includes a circumferential radially extending slot (44) in its outer surface through which an edge portion of the upper cutting blade (25) travels with the sheet firmly supported by the roller surfaces on each side of the slot (44). A blade lubricator (61) is attached to the upper head (12) and applies a thin film of lubricant to the blade edge (67) by direct engagement by a lubricating wick (65) while the blade (25) is rotating. The thin blade (25) is maintained in a sharpened condition by periodic engagement with a rotary sharpening tool (73) pivotally attached to the upper tool head (12) for periodic light sharpening contact with one face of the beveled blade cutting edge (67). Both the blade lubricator (61) and the blade sharpener (73) are retractable to inoperative positions to facilitate blade changing or blade reversal to provide extended blade life through periodic sharpening of the opposite blade edge bevel. The overlapping contact between the portion of the slitting blade (25) extending into the slot (44) in the lower supporting roller assembly (32) allows the lower tool head (28) and roller assembly (32) to be translated across the width of the sheet (13), as for repositioning, with a single positioning motor assembly (87) on the upper tool head (12).
