Abstract: The invention relates to a flow control device which comprises at least two control disks which are arranged coaxially with respect to one another, lie tightly against one another and can rotate relative to one another about their common axis, the control disks having a through-bore arranged eccentrically and leading through in the axial direction, and, on the side faces lying against one another, in each case a recess which, starting from the through-bore, extends along an arc of a circle about the axis of the control disks, so that if there is relative rotation, only parts of the opposite recesses overlap.

Abstract: A metering pump is disclosed which has a simple structure and in which conventional injectors can be used as pump elements. Injectors having different piston diameters can be inserted in a clamping means, and due to the arrangement of the elements of the metering pump on a base plate, a simple structure results.

Abstract: The invention provides a metering pump having pistons (13, 13′) which lie opposite one another, are guided in cylinders (11, 11′) and are connected to one another by a slide (14) which is moved in a reciprocating manner by a drive motor (201), a switching device (3) being arranged between the pistons (13, 13′) in a valve block (2), which switching device alternately connects the opposite cylinder spaces to a suction opening (4) and a delivery opening (5).

Abstract: In a window or door construction, comprising a frame, a casement/leaf attached moveably to the frame and mounting modules between the frame and casement/leaf, to control the casement/leaf an encircling control element is provided which can be driven by a motor and a handle module, is in engagement, in the various positions of the casement/leaf relative to the frame, with at least one mounting module and controls the sequence of movement of the mounting modules in such a manner that a clear sequence of the casement/leaf movements is ensured by the sequential succession of the control movements of the control element and of a slide, which is driven by the motor and can be connected to the control element.

Abstract: Manufacture of double or plural pane insulating packages by placing panes together with a spacer, thereby leaving an interspace at the periphery into which cement is injected. Two nozzles are used to inject cement into the interspace, starting from a common starting region and working in opposite directions around the periphery to a common terminal point. Conveyors and control systems are provided to mechanize the process.
