Title: Non-invasive continuous blood pressure measurement - applying pressure on outside of human body to relieve artery and compute blood pressure
IPC: A61B5/352
Filed: 1991-02-21
Abstract: The fundamental oscillation of the pressure signal is filtered out and the systolic blood pressure with max. pressure signal with positive fundamental oscillation. The diastolic blood pressure with min. pressure signal with negative fundamental oscillation are determined. The fundamental and associated harmonic waves of the pressure signal are filtered out. The filtered out fundamental waves and harmonics are added to a replica of the pressure signal, and the simulation of the pressure signal is used for computing the blood pressure. The first four harmonics of the pressure signal are filtered out. A R spike detector is provided which, from an ECG, determines the pulse frequency as a frequency of the harmonic. A storage for the pressure signal and a storage control are provided which is controlled by the R spike detector. A coefficient generator is provided for calculating frequencies of harmonics from the frequency of the fundamental oscillations. Adjustable band passes are provided which are adjusted to the frequencies of the harmonics and in certain cases to the fundamental wave to which respectively the pressure signal is supplied and a summator (29) is connected to its outputs. High and low passes (26,27) precede the band passes. ADVANTAGE - Improved so that effective suppression of movement artefacts and facilitates practically continuous blood pressure measurement.

Filed: 1992-01-17
Abstract: In a process for automatically binding bales produced in a bale press with at least one plastic strap which is conveyed, after the bales have been pressed, in the form of a loop through the pressing channel to a clamping device, a free end of the strap is connected to the tightened strap of the endless loop surrounding the bale to complete the binding of the finished bales and, after the binding has been separated, the other end can be prepared to form a new endless loop for the next bale to be pressed. Binding is made easy if, after passing through the pressing channel, the entire loop (16) is deviated and both sections (16a, 16b) of the loop (16) are firmly clamped. The section towards the bale overlaps the end of the endless loop (14) binding the bale (13) and is welded to it.

Title: High capacity refrigeration appts. for deep-freezing, air-conditioning or building heating - uses air as working medium compressed nearly isothermally and comprises continuously working rotating machines for delivering large vol. flows, e.g. with screws for compressing refrigerant vapour
Inventor: RADEBOLD HELMUT
IPC: F04C29/00
Filed: 1992-06-01
Abstract: Two such machines (1,2) are respectively mounted on a common shaft (4) as a refrigeration set, with air as a thermodynamic working medium. The first machine working as a screw compressor compresses the suction air. The heat produced during compression is given to the air to be compressed. Water is separated by a separator and drawn off partly by heating and partly by vaporisation. The isothermally compressed air after the separation of the water part, after passing through a recuperative heat exchanger (5), and with further cooling by air, enters the second screw machine. The air is expanded there at a very low temp. The separated water following the removal of the compression heat is led into an external heat exchanger in the circuit. The water is used for transporting heat and for the lubrication of the machines. USE/ADVANTAGE - Air conditioning or heating of buildings. Air at relatively low pressures can be used. Oil is no longer needed as lubricant. Wide temp. range.
