  • Patent number: 6762859
    Abstract: To generate engraving data (6), especially for an engraving cylinder, based on a vectorized printer's copy (1) and a screen stipulation (2), depending on the geometry of the elements contained in the printer's copy, within predefined variation range for the engraving data (6) at least one working screen (4) is chosen which deviates from the screen stipulation (2). In the printer's copy (1) first at least one line element is chosen. Afterwards within the variation range a working screen is determined which is matched to the periodicity of the determined line element with respect to density and/or angle. Then in the printer's copy (1) font elements are chosen and they are matched to the working screen using font hinting data. If necessary also the screen geometries which belong to the different process colors are stretched or flattened in the line direction and/or in the advance direction in order to be aligned to the chosen line element.

  • Patent number: 6462307
    Abstract: In a process for producing a stipulated intensity distribution of a working laser beam on an object surface, at least one first and one second component beam with a stipulated first and second intensity distribution are formed and the power of each component beam is changed in a controlled manner with switching times down to submicroseconds. The component beams at a third intensity distribution superimposed as the working beam are pointed at or into the object in order to achieve a different action as a result of a varied third intensity distribution of the working beam. In contrast to conventional processes the first intensity distribution Ib=a×fb(x, y, t) differs from the following one In=a×fn(x, y, t) by the value of the function fu(x, y, t) and no longer only by an altered linear value a. The process as claimed in the invention can be preferably used in the production of screen cells on an engraved cylinder.

  • Patent number: 5148778
    Abstract: A combustion chamber assembly for a two-stroke internal combustion engine has, in the upper dead point position of the piston, a space defined between the piston bottom and the cylinder head which is of the shape of a frustum of a right-circular cone or the shape of a right-circular cylinder. Surfaces of the piston bottom and the cylinder head extend tangentially to the wall of the space at 180.degree. offset from one another and are juxtaposed with surfaces of the cylinder head and piston bottom, respectively, defining narrow gaps squeezing fluid flow into this space tangentially form opposite directions to induce a vortex in the space in a single sense. The fuel injector opens axially into this space for autogenous ignition or self-firing or a spark plug extends axially into this space for external ignition.

  • Patent number: 5139846
    Abstract: The sealing strip has a main part (1') with a first sealing lip (6) for making sealing contact with a pane (7) or a filling element. The pane (7) is placed against the sealing lip (6) during assembly and rests on the top (10) of a lip (9'). A recess (13') is provided in a bridge (4') in the body of the sealing strip. The foot or base (16') is a second part (2'), which carries a second sealing lip (15') in contact with the other side of the pan (7'), fits into the recess. When the foot (16') is inserted into the recess (13'), the two sealing lips (6'15') are elastically deformed and pressed against the pane (7'). The inserted foot has a groove (19, 22) at one end in which a rib (14') engages. The foot (16') and hence the part ( 2') are thus firmly anchored in the main part (1').

  • Patent number: 5074089
    Abstract: The sealing device serves for tightly sealing the gap (6) between adjacent elements (1) of the inclined facade or roof against the access of water, by forming several sealing planes (A--A, B--B, C--C, D--D). To this effect a network of sealing pieces is created. These pieces each consist of a lower portion (21) and an upper one (22). The lower portion (21) also acts as a support for the elements and comprises a bearing surface (214) each between two sealing lips (212, 213). The upper portion (22) consists of a metal rail (22) and of a sealing stip (222) which overlaps the rail laterally and rest on the elements. That sealing strip which extends in the slope or direction of the fall comprises two substantially vertical webs (228). These webs form a drainage channel for water that may have penetrated, together with substantially parallel lateral sealing lips (224) which also seal the faces of the elements.

  • Patent number: 4437942
    Abstract: A wrap-on printing plate with first and second clamping bars along opposite sides thereof for installation on a printing cylinder is produced by providing a layer defining a printing plate body, forming from marginal portions of that layer, along opposite sides thereof, first and second foundations for the first and second clamping bars, respectively. These clamping bars are provided on such first and second foundations by interatomic bonding between the first and second foundations and the first and second clamping bars, respectively. To this end, the layer may, for instance, be electroplated on existing clamping bars in a special form, or, as presently preferred, material from which the first and second clamping bars are formed may be electroplated on the first and second foundations formed in marginal portions of the mentioned layer.

  • Patent number: 4309167
    Abstract: The cable is introduced into a sealing tube containing elastic sealing elements before entering the vulcanization chamber which is separated from the extruder. The elements have closed chambers which can be individually pressurized by, in each case, one line, while pressure regulation takes place by means of pressure reducing valves. Gaps can be provided between the individual chambers and they are filled by the heat transfer medium which brings about the crosslinking of the layer extruded onto cable and which passes out of the intake opening of vulcanization chamber. A leakage flow forms along the entire sealing tube and this passes through the openings of sealing elements and completely fills the annular clearance between the boundary of the opening and the cable, so that any contact between the cable and the sealing elements is at least substantially prevented. The gaps can be filled with a sealing liquid, which then forms the leakage flow instead of or together with the heat transfer medium.

  • Patent number: 4265225
    Abstract: Two identical header tube members are fitted to opposite ends of an absorbing member with a plurality of internal channels for circulation of a heat transport fluid to form a collector element. Each header has a header tube which is spaced from a header base plate by a tube saddle. The perimeter of the element includes a flange for joining it together with other, identical elements. Any number of such elements may be joined together to form a continuous, watertight sheet. Where the header tubes of adjoining elements connect, their spacing from the base plate leaves a passageway under them between adjacent tube saddles. Water can run off the surface through the passageway in the direction of slope of the surface upon which the sheet of elements is installed.

  • Patent number: 4195850
    Abstract: In order to form a tighter seal, especially at corner butt joints, between polygonal construction plate elements which are pressed together at their edges with an intervening gasket strip, the strip is provided at its critical sealing section with a second material of greater elasticity than the first, main gasket material. A third material which plastically deforms under pressure is partially embedded in the second material. The pressure of the second material when compressed forces the third material to flow into low seal pressure spaces and gaps of the seal to form a bonded seal with a seal pressure which is distributed by the deformation of the third material. Various configurations of the gasket cross-section and of corner segments are described.
