Title: Quasi-coherent synchronisation of two different frequencies - measuring sinusoidal signal frequency and comparing with reference frequency related to both input frequencies
Inventor: STELZEL FRITZ
IPC: G01S1/00
Filed: 1990-11-27
Abstract: The process measures a frequency (f1) of a sinusoidal signal and compares it with a rated reference frequency (fN). The latter corresponds to a mean frequency between those (f1, 2) of two input signals (sf1, 2), to obtain a shift frequency (fv) with a corresp. sign. A VCO (5) with a frequency, corresp. to the mean frequency, is brought into oscillation at a specified, related frequency. The first two frequencies (f1, 2), as a mirror-image of the reference frequency, are applied to a phase comparator (9) via controlled gate circuits (7, 8) after time intervals (T), inversely proportional to twice absolute shift frequency. The comparator output voltage is at times proportional to the difference between the first two frequencies. USE/ADVANTAGE - For navigation satellites, with precise distance measuring, and time signal transmission.

Patent DE-4114677-A1 (DE)
Inventor: BERGNER MARIO
IPC: A61N1/04
Filed: 1991-05-06
Abstract: This invention relates to a plaster arrangement for the electrical prevention of muscular distortion. It is the intention of the invention to provide electrotherapy more efficiently and in all more practically by stable galvanisation without an external power source. This intention is achieved by the invention in that a flat electrode of different metals is arranged on either side of the region to be treated. According to the invention, on the other side, the one away from the body, is arranged another metal electrode of which the metals may be the same as those of the two skin contact electrodes but must always be fitted with the opposite polarity in the sense of the electrochemical voltage series. The two compact bimetal electrodes produced are insulated at the edge against electrolytic short-circuiting and secured to the body with electrocardiograph electrode plasters obtainable from medical suppliers. Moreover, with a suitable choice of metals, two additional galvanic elements connected in series with the galvanic element already known from literature are produced from two different metals applied on the skin.

Patent DE-4139555-A1 (DE)
Inventor: KNEER ROLAND
IPC: A61J1/10
Filed: 1991-11-30
Abstract: The bottle-shaped container is made in a coextrusion blow molding process and has a dimensionally stable outer container and an easily deformable inner bag which consist of different thermoplastic materials that cannot be welded to each other. The preform has a diameter greater than that of the bottle neck so that, when the blow mold is closed, the blow mold halves squeeze off excess material not only on the bottom, but also in the shoulder and neck area. Unwelded seams of the outer container are thereby formed in the shoulder and neck area. In the bottom area the outer container is closed by a weld seam which has been formed by displacing material, the weld seam of the inner bag being fixed in said area. After negative pressure has been applied to the inner bag, holes are formed in the upper area of the outer container for the purpose of a permanent pressure compensation. All openings in the outer container are covered by the pump housing. The container operates reliably in the upside-down position.
