Title: Tomography without using X=rays - applying identical EM wave trains with one having gap from interrupter controlled by computer
Inventor: HECKMANN KARL PROF DR MED
IPC: A61B5/053
Filed: 1990-01-17
Abstract: The e.m. wave trains are applied directly sequentially at the same position to pass through the object or patient.  One wave train has a gap.  The density of the tissue is calculated from the resultant currents of the wave trains. Two wave trains can be switched-over through a computer and the resultant currents can be stored in two different memories after measurement in the measuring appts.  The gap in one train can extend over the whole surface of the object to be imaged.  In the region of the gap, only the other wave train is effective, i.e. it depends on the changing resistance of this section of tissue.

Title: Process for lining insides of pipelines - uses resin-impregnated hose with weak spot near end of branch pipe
Inventor: SCHMIDT MANFRED
IPC: F16L55/179
Filed: 1990-10-15
Abstract: The process for lining the insides of pipes consists in introducing a resin-impregnated hose, provided on the outside with a protective foil, in the collapsed state into the pipe line whereupon the hose is then inflated and the resin sets. When lining the inside of a branch pipe leading off from an alrady lined mains pipe the hose foil is provided with a circumferential weakened area, such as perforation, adjoining the end piece of the hose inserted in the branch pipe. The hose is then drawn into the branch pipe so that the weakened area lies flush with the inner lining of the main pipe. The hose is then charged with compressed air so that the resin emerges through the perforation of the hose and sealingly connects with the inner lining of the main pipe. USE - To provide inner lining for branch pipes from already lined main pipes.
