Patent DE-4210705-A1 (DE)
Title: Frequency=voltage converter for vibration-type level detector - has integrator with asymmetric charging time constants for forward and backward integration
Inventor: RAFFALT FELIX DIPL ING
IPC: G01D5/243
Filed: 1992-04-01
Abstract: The converter converts a pref. rectangular oscillator signal, whose frequency decreases with increasing level, from the detector into a level dependent output signal. An integrator (24) controlled by an internally generated signal (D) with the period of the converter input signal (A) produces the level dependent signal (H). The integrator has asymmetric charging time constants for up and down integration. Its output signal follows the input signal more rapidly as the frequency reduces than as the frequency increases. ADVANTAGE - The level detector arrangement has a frequency-to-voltage converter with reduced noise sensitivity.

Title: Low frequency noise elimination from signal - e.g. PWR neutron flux signal, using adaptive filter
Inventor: DREYER HANS-JUERGEN DIPL ING
IPC: H03H21/00
Filed: 1992-04-06
Abstract: Noise-suppressing processing of a signal (x(t)) including low frequency noise is carried out by using first (Ro) and second (Ru) regulating circuits to form the upper (yo(t)) and lower (yu(t)) envelope limits of the signal (x(t)) from the two envelope limits. Also claimed are (i) use of the process for noise-suppressing processing of a signal which, in the unfiltered state, can lead to attainment or exceeding of signal limits not attained by the noise-free signal; and (ii) an adaptive filter for carrying out the process. The adaptive filter pref. comprises two parallel-connected regulators (Ro, Ru) which produce the upper and lower envelope limits of the noisy signal and which are connected to a summation circuit (MW) for producing a mean signal. USE/ADVANTAGE - Useful for processing neutron flux signals obtd. from neutron flux density measuring sensors on or in nuclear reactor (PWR) pressure vessels and which are used to determine the short term corrected thermal reactor power (claimed). The process is applicable to noise frequency bands which cannot be treated by conventional high pass, low pass or bandpass filtering, produces practically no dynamic loss, is independent of the noise amplitude and frequency, and can be carried out with various systems, e.g. analogue operational amplifier technology or digital technology.

Patent DE-4224446-A1 (DE)
Inventor: AYDNIK HEINZ
IPC: A61G7/00
Filed: 1992-07-24
Abstract: Conventional devices for washing patients usually comprise a water-impermeable plastic sheet (3) which can be inserted in a hospital bed (1) and whose edges are drawn upwards on all sides to form a trough and reinforced against bending-over. Washing water can be fed in or led away via a feed line (5) and an outflow (7). The plastic material normally used is PVC which, however, is difficult to sterilize because of its low temperature resistance and its low chemical stability caused by the plasticisers and moreover forms a good culture medium for pathogenic organisms, e.g. bacteria, due to its relatively high surface porosity. As a solution to this problem the invention proposes to prepare the plastic parts of the device for washing patients from a polyorganosiloxane compound or a highly crosslinked fluorinated plastic. In addition, antiseptic filters (9), preferably UV emitters, may be built into the feed line (5) and/or the outflow (7) in order to reduce the risk of infection.
