Abstract: 1. Process for metering small quantities of liquid without leaving a residue by means of a micro-piston pump having a capillary cylinder in which a piston, which fits in gastight manner therein, is mounted so as to be movable between a top dead centre and a bottom dead centre, the cylinder at its end located opposite the base of the piston opening into a twoway valve which connects the space in the cylinder alternately to an inlet and to an outlet (which connects the cylinder to the atmosphere during the first stage of the intake operation), characterised in that the piston and the valve are moved in such a way that, during the intake operation, first a defined quantity of air and then a defined quantity of liquid is transported into the cylinder, the quantity of air being such that, as the piston moves downwards to bottom dead centre, all the liquid is expelled through the outlet line.

Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.

Abstract: A metal frame arrangement (20, 21), for use as or in door frames, window frames (22), window casements (23) or the like, comprises a frame made of concave metal profile. The frame (20, 21) comprises two pairs of mutually opposite frame portions which are angled at right angles relative to the adjacent neighbouring frame portion. The frame (20, 21) is made into a coherent piece in a longitudinal continuous and sectionally angled contour, by means of local cavities (31, 35) in the metal profile and longitudinal deformation of locally uncovered portions (32, 36, 37) of the metal profile, the deformation by means of the material of the metal profile forming angle reinforcing and angle bracing means (32', 38) just by the apex of the angle between two neighbouring frame portions. A process for the production of the metal frame (20, 21) comprises that cavities (31, 35) in a side portion or side portions of the profile are removed, after which a section of web portion (20c) or one web portion (21f) of the profile uncovered by the cavity (31, 35) is finished to form an angle bracing and angle reinforcing means (32', 38) for establishing frame portions angled at right angles relative to each other. The angle bracing is effected simultaneously with the undertaking of the angle bending of the frame plate.

Granted: 2001-01-16
Abstract: A process for production of large calibre plastic tube, in which a hollow thermoplastic profile of rectangular cross-section is extruded and is coiled on a drum helically with contiguous turns with adequate deformability, and in which during the coiling operation the turns are welded together at the contact surfaces by a butt-welded seam under axial pressure and heat. The hollow plastic profile is moulded in an extrusion tool to form a multi-cell profile having outer profile walls and cell-forming webs and at the same time and/or thereafter, by internal cooling of the outer profile walls and the cell-forming webs, is sized and given a design strength which is stable up to a predetermined critical pressure. The calibrated mufti-cell profile is again heated at the contact surfaces to the welding temperature of the thermoplastic material. The butt-welded seam between the turns is welded with an axial pressure below the critical pressure of the design strength. Extrusion tools for performing the process are also described.

Abstract: In  a  tightly  coupled  multiprocessor  system,  I/O interrupts  are  distributed  to  respective  processors  in accordance  with   load  conditions   of  the  processors. Interrupt  arbitration  circuits  provided  in  respective processors receive an interrupt request from an I/O device, effect interrupt arbitration using a parameter indicating the load condition of each processor as a first interrupt priority PPR.  If the arbitration fails to determine a sole processor,  additional  arbitration  finally  selects  a  sole processor on the basis of the second interrupt priority RRPR which is variable circularly.
