Title: High speed track magnetic rail joints - have spacers and clamps, elastomer fillings, and fish plate with slots allowing movement
Inventor: TSCHEMMERNEGG FERDINAND DR TEC
IPC: E01B25/30
Filed: 1979-01-02
Abstract: The joint construction is esp. for L-sectioned magnetic rails in high-speed tracks, comprising stator or magnet anchor rail, guide-rail and emergency running rail. Two or more intermediate rail pieces (11-15) are spaced out in gaps (8) formed by two magnetic rails (5, 9), dividing them into small gaps (10). Clamping profiles (18-22) are fixed inside these, at an interval, without screws protruding. Intervals and gaps are filled with elastomer material. An abutment fishplate again at an interval, covers the joint gap length inside the clamps, being displaceably connected to the intermediate pieces, clamps and one rail by screws (32, 33) sunk in slots, and firmly screwed to the other rail. The slot for first rail connected is long enough to allow for expansion. This reduces magnetic field interruption, and provides smooth, quiet travel over joints.
Patent DE-2900446-A1 (DE)
Inventor: LAESER BERNHARD
IPC: D01H1/00
Filed: 1979-01-08
Abstract: Pipe screw connections, especially in gas and water pipes, are usually sealed off by means of hemp wound on the external thread. Instead of having to draw individual tufts from a tress, as hitherto, a non-spun fleece strand is wound onto a tubular piece and a reel is thus formed. The winding takes place under low tension and with a high pitch, so that only crossings occur in adjacent turn layers. Such a reel (3) allows quicker working, especially when it is used together with a holder (H) provided with braking member (B), in order thereby to wind the hemp (1) onto the thread (G) of a pipe (R). For this, either the holder can be guided around the pipe in the direction of the arrow (K) or the pipe can be rotated while the holder remains stationary. <IMAGE>

Title: Radial seal for rotating propeller shaft in ship - has hydraulic cylinder controlling water leakage to provide variable lubrication
Inventor: KIRMA SAFA DIPL ING
IPC: F16J15/40
Filed: 1979-05-08
Abstract: The radial seat consists of a slide ring (1) held by a support ring (2). The two rings are split and the resulting radial cap is filled with a rubber seal (4). The slide ring rests on the outside of a socket (5) attached to the flange of the propeller's hub. The shaft (8) passes through the socket coaxially. The sides of the gap in the support ring are formed into flanges (9, 10). A bracket (11) engages these flanges and has a hydraulic cylinder (24). The hydraulic cylinder acts on the bracket and therefore on the flanges such that the gap between the support ring's sides and, therefore the gap between the sides of the slide ring, is changed thereby allowing a controlled amt. of water to leak into the region of the seal to provide lubrication. The amt. of leakage is ascertained via a current monitor and conveyed to the hydraulic aggregate via an electrical control.

Patent DE-2942950-A1 (DE)
Inventor: SCHMID HANS DIPL ING
IPC: G11B15/43
Filed: 1979-10-24
Abstract: The generation of tape tension, based on the capacity for elastic flow of elastomeric incompressible layers, in a tape transport apparatus employing at least one capstan in contact with supply and take-up reels of tape is accomplished by producing a higher compressive force at the point of contact between the take-up reel and the resiliently deformable peripheral portion of the capstan than at the point of contact between the supply reel and the capstan. The difference in compressive forces is brought about by an additional force which is produced by means of a drivable rotating body and is transmitted to the tape reel carriers by means of a cable which is guided over this rotating body.
