Title: Safety device for hydrocarbon tanks - using a separating floor which together with the main floor forms a gas tight closure
Inventor: RUPF-BOLZ OTTO DIPL ING
IPC: B65D90/507
Filed: 1974-11-11
Abstract: The safety device for liquid tanks especially large tanks containing hydrocarbons or other liquids endangering the environment, indicates a leakage. On the tank floor and in the border area between the floor and the tank wall a separating floor (3) is fitted which provides a gas tight closure of the floor cross section close to the floor which together with the main floor (1) forms a gas filled space (6) free from the liquid contained in the tank. The measurable or adjustable gas pressure nearly corresponds to the hydrostatic pressure of the container liquid with means which balance any difference in hydrostatic pressure arising when the separating floor is not in a horizontal position.

Title: Closed cycle trochoidal gas engine - has external combustion and can burn a wide variety of fuel with economy
Inventor: FINKELDEY KARL-HEINZ
IPC: F02G1/04
Filed: 1974-12-30
Abstract: The working cycle comprises compression of the working gas, which is incombustible, in a reciprocating compressor (2), followed by delivery to a heater (3). Here, heat is generated by combustion of any gaseous fuel, externally to the working gas circuit; the heated working gas is then led to a trochoidal piston engine (1) which it enters through one of two inlet ports on the same side of the casing. Here it expands and acts on the piston, some of which energy is used to drive the compressor, the remainder being available as an output. The gas then exhausts on the opposite side of the engine casing and passes to a cooler (4), and thence to the compressor inlet.

Title: Computer assisted sample management - is used in clinical laboratory and identifies, assigns and records samples by automatic process
Inventor: SCHMIDT BERND DR
IPC: G01N35/00
Filed: 1975-09-25
Abstract: A method of dealing with samples is used in a clinical laboratory, typically associated with a hospital. The samples are identified, assigned to test equipment, and the results recorded by computer, rather than by record cards associated with the samples, is presented. Each sample when it arrives at the laboratory, has with it a descriptive card, identifying the patient, type of sample, and so on. The information on this is fed to a computer, which records the information, assigns the sample to test equipment and prints out the type of test required. The sample vessel itself then has only a number carried with it, reducing the complexity of handling. A more even laboratory loading is also possibly by this method than by the traditional one.
