Title: Medical subcutaneous fluid injection unit - has valve system to maintain suction on skin inside chamber around injection zone
Inventor: WAGNER WOLFGANG DR MED
IPC: A61M5/42
Filed: 1977-09-05
Abstract: Apparatus for subcutaneously injecting a treatment fluid while maintaining a suction on the skin around the area in which the cannula is inserted, as in the main patent is portable and can be manually controlled. The vessel containing the treatment fluid can be removed when empty, and can be replaced without requiring adjustment for the rate of feed.

Title: Flat surface heat transfer element - having trapezium shaped channels with C=shaped profiles pushed into them, the resulting sheet being dip galvanised
Inventor: SCHOELL GUENTER PROF DR ING
IPC: F24S10/50
Filed: 1977-11-04
Abstract: Flat heat exchanger element has sheet with channels pressed into with rectangular or trapezium section. Into these section sheet profiles are inserted to create flow passages for the heat transfer medium. These are held in by pressing operation. The element is completed by a galvanising clipping operation so that all the crevices between the channels and the inserts become filled with Zn. This subsequently sets to give pressure tight and sealed channels. For use as water and air heat exchangers esp. in solar energy collectors. Conventional fabrication requires spot welding. The plate described avoids this and is thus cheaper to produce.

Title: Force measurement using amorphous iron alloy active element - with reversible magnetic characteristic variations under load and oscillator
Inventor: SCHEINHUETTE HANS-JUERGEN
IPC: G01L1/12
Filed: 1978-12-14
Abstract: A force measurement cell consisting of a force transducer and corresp. electronic signal generator operates on different principles from other devices yet with similarities to stretched fibre devices whose oscillation frequency varies with tension. It gives an easily measured or directly displayed electrical output. The electrical signal is derived from the variation in magnetic characteristics of a force transducer whose active element is a closed loop of amorphous ferrous alloy. The output is in the form of the frequency of one or more electrical oscillators (6) contg. such active elements (3). The amorphous ferrous alloy exhibits reversible changes in magnetic characteristics under mechanical load. Such transducers may be used to measure bending, compressive torsional and other loads acting simultaneously.
