Patent DE-3244080-A1 (DE)
Title: Fan-type rotor
Inventor: STENZEL KARL
IPC: B63H1/14
Filed: 1982-11-29
Abstract: A boat or ship drive which compared with conventional similar types of drive is distinguished by far higher efficiency. As apparent from the drawing, the characteristic of the type of construction ensures that large undesirable turbulence is avoided during rotation of the fan-type rotor but the thrust forces become fully effective in the axial direction. A banked-up flow on the inner arches 1a and 2a as well as a low pressure produced by a fast flow on the outer arches 1b and 2b give rise to the thrust forces. <IMAGE>

Patent DE-3307100-A1 (DE)
Title: Method and device for processing workpieces
IPC: B23Q7/03
Filed: 1983-03-01
Abstract: Workpieces are processed at at least two tools arranged in a conveying section behind one another in the conveying direction. To this end, the workpiece is conveyed to the individual tools at a preset conveying speed. When so required, the workpiece is transferred between the individual tools. For transferring purposes, the workpiece is first conveyed into a starting position. The speed with which the workpiece is conveyed into the starting position is greater than the preset conveying speed with which the workpiece is conveyed between the individual tools. From the starting position, the workpiece is conveyed away so that further processing operations can be carried out, before the next workpiece assumes the starting position. The associated device makes provision for arrangement of a rapid conveying section upstream of the starting position, whose conveying speed is greater than that of the conveying section in the region of the tools. The conveying speed of the rapid conveying section is matched with the conveying speed of the conveying section on the one hand and a conveying speed maintained during transfer on the other hand.

Title: Balloon dilation apparatus with a cutting tool on a primarily single-lumen multi-purpose catheter
Inventor: SCHUBERT WERNER DR MED
IPC: A61F2/958
Filed: 1984-01-26
Abstract: The double-lumen balloon-tipped catheter according to Grüntzig is at present regarded as being the most effective, and is frequently also used for the important, percutaneous, transluminal angioplasty, preferably on moderately arteriosclerotically constricted coronary arteries. In contrast, according to patent claims 1-18 an improvement consists in the use of a primarily single-lumen multi-purpose catheter which also has a balloon or balloons; the otherwise standard balloon is expediently divided in three parts and also has a cutting tool on the top of the single balloon and is set lengthwise like the latter, and at the same time is arranged via slits which are also set lengthwise on the catheter which has relatively thick walls and is incompressible. The single lumen of this multi-purpose catheter was already proposed in P 3326648.4, Dr. Schubert. The front nozzle can also be closed with likewise long accessory instruments, such as cannulas. The present multi-purpose catheter can also become the guiding catheter by introduction of a pre-shaped spiral which is connected to a torsion-proof retaining wire at the proximal end also for pushing on. The frontal nozzle body may also comprise a plurality of nozzles, so that further guide tracks for various functions can at the same time be used in the multi-purpose catheter. A special catheter having a balloon and a cutting tool for the elimination of urethral structures is presented.

Patent DE-3412065-A1 (DE)
Title: Loading bridge
Inventor: ADLER HEINZ
IPC: B65G69/28
Filed: 1984-03-31
Abstract: The invention relates to a loading bridge, the superstructure (3) of which is pivotably articulated at one end to a stationary ramp (1) and has at its other free end a telescopic projection (9) which is pushed under the bridge superstructure (3) when the loading bridge is in the rest position and is telescoped in the operating position, it being possible to place the loading bridge in this position onto a platform to be loaded and/or unloaded, with one or more supports (25), so that the bridge superstructure (3) can be placed, in the rest position of the loading bridge, on one or more abutments (28). Known loading bridges have the disadvantage that they must be fully raised for extension and retraction of the projection. The object of the invention is to devise a loading bridge of the above type in which it is no longer necessary, before moving the loading bridge out of the rest position into the operating position or out of the operating position into the rest position, to raise the bridge superstructure into the fully extended position and only then to extend or retract the projection, but in which the projection can be extended or retracted directly from virtually any position. The object is achieved by arranging the support or supports (25) on the projection (9) in a pendulous fashion. <IMAGE>
