Patent DE-4229662-A1 (DE)
Inventor: WINKLER HERMANN DR
IPC: C02F11/12
Filed: 1992-09-04
Abstract: A process is disclosed for removing mercury from effluents of flue gas purification plants. The crude effluents from the flue gas scrubbers, which carry solid materials, are treated with an excess of oxidizer in order to quantitatively convert mercury into its soluble bivalent form. Only then the remaining solid materials are separated and washed (10; 14). The dissolved mercury is bound by a ion exchange resin and separated (24). The large amounts of flue gas purification slurries are thus rid of practically all mercury, whereas the proportion to be dumped of mercury-contaminated special waste is kept small.

Title: Generating correction function eliminating phase and amplitude errors in compressed signal - producing Fourier transform reference functions of ideal and optimal filters to provide correction function in time range of inverse Fourier transform
Inventor: MOREIRA ALBERTO
IPC: G01S7/40
Filed: 1992-11-30
Abstract: To generate a reference function (hi(t)) an error-free, frequency modulated signal (So(t)), a signal (Sf(T)) containing phase and amplitude errors, a reference signal (ho(t)) corresponding to a conjugated, complex, time inverted function of the error-free signal and a reference signal (Hf(t)) corresponding to a similar function of the input signal, are each Fourier transformed. These signals are all multiplied together in twos. The reciprocal of the signal (Ff) from the first multiplication is multiplied with the output signal (Fo) from the second multiplication. The result is multiplied by the Fourier transformed signal (Hf). This is inverse transformed to give a reference function (hi(t)). A second reference function (hf(t)) is generated according to optimal filter theory. The reference functions are Fourier transformed in an FFT device (6.2, 6.5). The reciprocal (1/Hf) of one transform signal is multiplied with the other. The result is inverse transformed in an IFFT device (6.7) to generate a correction function (hkorr(t)). ADVANTAGE - Expands ideal filter concept to eliminate phase and amplitude errors in compressed signals.

Title: Electric motor having a pulse transmitter
Inventor: TRAEGER FRIEDRICH
IPC: H02K29/10
Filed: 1993-08-20
Abstract: Electric motors, in particular DC motors which have no commutators and are used as stepping motors, require a pulse transmitter in order to detect the rotation speed and/or the rotation position of the rotor, which pulse transmitter has a probe head (sampling head) for scanning scanning marks on an element which rotates with the rotor.

Title: Freeze-dried polysaccharide bio-matrix useful as pharmaceutical or cosmetic carrier - comprises mixt. of natural and modified material e.g. pectin, alginate, agar, cellulose ether deriv. etc.
Inventor: SUWELACK WOLFGANG
IPC: A61K8/64
Filed: 1993-08-18
Abstract: Claimed is a freeze-dried biomatrix comprising 10 to 80 wt.% of natural polysaccharides and 20 to 90 wt.% modified polysaccharides. Pref., the natural polysaccharides are e.g. pectins, alginates and agar. The modified polysaccharides comprise cellulose ether derivs. and additionally spun fibres such as polyester, polyamide, polyvinyl alcohol, wool, cotton, silk and viscose. USE/ADVANTAGE - The matrix is suitable as carrier for pharmaceutical and cosmetic effective agents (0.1-20 wt.%, pref. encapsulated in liposomes), for the application of effective agents and as wound lining. Compared to collagen sponges of the prior art which are either unstable in water or which contain cross-linking agents of animal origin, the new biomatrix has the features of collagen sponges but lacks preservatives, wetting agents and perfumes. The use of only a few substances for the production of the biomatrix reduces the interaction between them during freeze drying and simplifies quality control. An improved dosage accuracy of effective agents, e.g. vitamin A-derivs., was found. Freeze drying results in a sponge like biomatrix that can easily be rehydrated and which forms a gel when moisturised. The biomatrix not contg. and spun fibres can be massaged into the skin so as to disappear completely. When the biomatrix contains spun fibres these have to be removed after, e.g. cosmetic, treatment.

Patent DE-4406286-A1 (DE)
IPC: A61B5/22
Filed: 1994-02-26
Abstract: The invention relates to a system and a process for determining the individual anaerobic threshold of a living organism. The individual anaerobic threshold is determined using a system for the dynamic determination of the respiratory, metabolic and/or ventilatory variables during a process or influence promoting lactate production. The system comprises a computer (18), with a display unit and a computational unit, and, connected via an analyser (22) to the computer, a device such as a mask (20) for determining the respiratory minute volume as well as the O2 and CO2 content of the respiratory minute volume of the inhaled and exhaled air, respectively. In the computational unit, a variable x is calculated, as a function of the work (P) performed per unit time, from the measurement variables (i), (ii) and (iii), according to an algorithm (iv). A curve is adjusted to, or plotted from, the values x = f(P). The point on the curve x = f(P) at which the derivative dx(P) / dP is equal to zero or exhibits maximum discontinuity defines the load value (PIAT) corresponding to the individual anaerobic threshold. The individual anaerobic threshold of the living organism can therefore be determined without continuous lactate determination on a blood sample.
