Title: Stitch-controlled sliding-tongue (compound) needle for knitting machines
Inventor: LINDNER HEINZ
IPC: D04B35/06
Filed: 1981-06-16
Abstract: The invention concerns a stitch-controlled sliding-tongue (compound) needle comprising a sinker-shaped tongue which is guided in a groove of the needle shank and has two cams rising above the needle shank for the opening and closing of the needle hook by the stitch and which is assigned in its front end position an abutment on the needle shank. In order that the needle life may be extended, the abutment between the tongue and the needle shank is to be made self-cleaning. This object is achieved when the abutment is immediately adjacent to a relatively large clear space. This clear space can be an upwardly directed recess in the tongue above the abutment. Similarly, there can be provided within the tongue a recess which communicates with the abutment via a channel. The same effect is produced by abutment feet upwardly directed on the guidance continuation and which cooperate with abutments within or above the needle shank. The guidance edge in the tongue is longer than the stroke difference between needle and tongue. <IMAGE>

Title: Cartridge for a pile of individual sheets
Inventor: MOSER KURT
IPC: B65D83/08
Filed: 1981-11-27
Abstract: A cartridge for a pile of individual sheets, in particular copying paper coated on one side for photocopiers, is described whose cardboard container, which can be torn open on one side, is provided on one inside with a glued-on sheet of the sheet pile. This bottom sheet of the sheet pile is glued with the coated side to the side wall of the container so that the friction conditions between the individual sheets of the pile remain the same from sheet to sheet and do not change even when the final sheets of the pile are removed automatically. The advantage of undisturbed sheet removal is therefore achieved as well as the advantage that the individual sheets can be contacted by the removal devices on their non-coated rear side.

Title: Converter arrangement for phase-coupled carrier frequency transmission systems
Inventor: WISCHMANN ULRICH DIPL ING
IPC: H04J1/04
Filed: 1982-03-11
Abstract: A converter arrangement for carrier frequency transmission systems is proposed in which phase coupling of all carrier frequencies arriving for distribution is achieved with comparatively simple means. The converter arrangement comprises a plurality of double converters (10), each with an input converter (11) and an output converter (12). The input converters convert the respective input channel to an intermediate frequency which is identical for all converters and the output converters convert the intermediate frequency channel in each case to a selectable output channel. All output channels are associated with a predefined frequency raster. An essential feature of the invention is that a single reference frequency generator (51) is assigned to all the double converters of the converter arrangement. Each of the input converters contains a PLL oscillator circuit in which a phase comparison is carried out between a first comparison frequency (fV1) derived from the intermediate frequency (fZ) and a reference frequency (fR) derived from the reference frequency (fB) of the reference frequency generator. A PLL oscillator circuit is also associated with the output converter, in which circuit the phase comparison is carried out between the second comparison frequency (fV2) derived by division from the oscillator frequency (fO2) and the reference frequency (fR). <IMAGE>

Abstract: The invention relates to a ceramic tubular capacitor whose extruded body (1), which has a circular ring-shaped cross-section, has two mutually perpendicular central webs (2) which split the central cavity into four quarter-circular spaces (4a, 4b). In order to be able easily to provide an extruded body (1), which can be produced easily, with the metal layers (8, 9) of the two plates, using which a relatively high capacitance per unit volume can be achieved, a cavity (3b, 3a), which surrounds the adjacent central space (4b, 4a), originates from each central space (4a, 4b). The cavities (3a, 3b) are constructed in the shape of quarter-arcs. The metal layers (8, 9) of the plates cover the surface of the central spaces (4a, 4b) and continue in the cavities (3b, 3a). Connecting wires (6) are firmly soldered at their fork-shaped split ends (7) to the metal layers (8, 9) in the central spaces (4a, 4b), the fork-shaped ends (7) of the connecting wires (6) being twisted through 90 angular degrees with respect to one another in the axial projection direction. <IMAGE>

Title: Device for the automatic coupling and decoupling of oil return lines
Inventor: KOLPAK FRIEDHELM DIPL ING
IPC: B21B31/00
Filed: 1982-10-30
Abstract: The invention relates to a device for the automatic coupling and decoupling of oil return lines to oil-lubricated roll bearings of horizontal rolls mounted in chocks, especially in flat rolling mills. To reduce the roll changing time and avoid oil residues running out when the return lines are detached during the roll change, the present invention proposes to flange an oil sump pan (9) to each chock (4) of the bottom roll (2), into which the oil return line (6) of the upper and lower roll bearings open. The oil sump pan (9) is releasably connected to the main return line, with the interposition of a valve which closes automatically during roll removal. If two valves (18, 29) are used, both the sump pan (9) and the return line (12) can be sealed in a leak-tight manner when the rolls (1 and 2) are removed, with the result that it is both impossible for oil to escape and for dirt to penetrate into the return line (12). <IMAGE>

Title: Piston pump, in particular self-aligning piston pump
Inventor: RIEDLINGER HEINZ
IPC: F04B39/12
Filed: 1983-09-15
Abstract: A piston pump, in particular a self-aligning piston pump (1) has a pump part (2) which communicates with a drive casing (3); in this instance, the pump part (2) comprises a pump cylinder (5) and a pump head (4). In such a pump (1), provision is made that the pump part (2) is attached to the drive casing (3) in such a way that a gap area (19) is left free and the interior (20) of the drive casing (3) remains open to the outside. Consequently, the casing interior (20) communicates with the surroundings of the pump (1), so that air exchange and, as a result, cooling of the pump part is possible. The heat-sensitive parts located in the drive casing (3), in particular the bearings located there and the lubrication thereof, can be protected against excessive heating. A particular design feature is that the height of spacers (24) which are disposed between the pump part (2) and the drive casing (3) can easily be adapted to different piston strokes and different piston radii (r; R). <IMAGE>
