Patent DE-3214423-A1 (DE)
Title: Knotting device which knots wool-yarn pieces into a hand-knotted carpet warp
Inventor: NANN ERNST
IPC: D04G3/04
Filed: 1982-04-20
Abstract: The knotting tools executing the knotting operation can be seen numbered on the knotting machine shown in the picture. As seen in more detail, the mode of operation of the developed device is that the individual wool-yarn pieces to be knotted in, the respective yarn is taken off from the wool-yarn holder (23) by means of the threading-in segment (18) of the eyelet (19), inserted into the yarn channel (14) and brought into the loop form by the fork-shaped feeder (15). The loop gripper (4) on the knotting ring (3) grasps the loop, draws it past round the warp yarn applied to the yarn holder (7) and opens the loop at the separating pin (8). The stitching needle (9) bearing behind it and movable on all sides widens the loop when it is inserted and keeps it open by means of the needle stop (13), so that the knot (28) can enter from below on the sliding rod (32), the sinker (29) being opened by the stop pin (33). The knot helper (25) transports the yarn ends into the knotting sinker (29) which closes during the downward movement, thereby clamps the yarn ends and thus pulls the knot taut. When the knotting ring (3) frees the orifice (35) provided, the warp yarn returns to its old position, so that a subsequent warp yarn is taken off out of the groove (42) on the yarn slide plate (34) by the take-off needle (38) and passes through the orifice (35) into the knotting ring (3) for the next knotting operation. <IMAGE>

Patent DE-3328293-A1 (DE)
Title: Adjustable radial piston machine
Inventor: DWORAK WILHELM
IPC: F04B1/06
Filed: 1983-08-05
Abstract: The radial piston machine has a fixed guide journal (12) bearing a rotor (22). In the approximately radially extending bores (25) of the rotor, pistons (26) are fitted whose ends slide along the inside of a cam ring (43) which can be displaced axially with regard to the guide journal (12). The internal perimeter of said cam ring is of circular shape near one end face, but has widenings (44, 45) extending towards the other face which are situated diametrically opposite to one another and, in cross-section, are approximately elliptical in shape. When the pistons move from the circular region to the elliptical region, they execute strokes and convey pressure medium through an orifice (39) arranged in a slide (37). A differential pressure force results there, by means of which the slide, interacting with a regulating spring, adjusts the cam ring in such a way that constant throughput is achieved. The radial piston pump described is particularly suitable for low and medium pressures. <IMAGE>

Title: Multi-layer repair sealant for flat roofs
Inventor: HEYEN JOHANNES
IPC: E04D11/02
Filed: 1983-08-20
Abstract: The object of the invention is to produce on site a sheet of equal quality to that produced in the factory. The multi-layer repair sealant for flat roofs is suitable since the bitumen polymer combination contains neither solvent nor emulsions and the final strength thus results by cooling. It is furthermore suitable since the multi-layer structure - bitumen/polymer, mat with or without woven fabric, bitumen/polymer, particulate covering - results in high extensibility, on account of the bitumen/polymer layer, and no fracturing as well as high tear strength, on account of the mat insert with or without woven fabric. Since the bitumen/plastic combination is spread or sprayed on, the sheet adapts perfectly to the substrate.

Title: Displaceable hydraulic cushion as a drawing cushion for a multiple-die press with a sliding table
Inventor: GRIESINGER KARL
IPC: B21D24/02
Filed: 1984-02-15
Abstract: The invention relates to a drawing cushion for multiple-die presses with a sliding table. Since it is not always known beforehand with a drawing press which working stage will be used as the drawing stage, the customary practice hitherto has been to provide all the stages with a drawing cushion. In order to avoid this disadvantage, the invention now proposes that only one drawing cushion be provided and that this be arranged in a manner which allows it to be displaced between the individual working stages.
