Title: Radio data signal receiver esp. for car
Inventor: LIMAN HELMUT
IPC: H04H20/26
Filed: 1991-02-01
Abstract: A changeover switch (8) connected to the input of a digital memory (9) is so controllable that during the receipt of the adjusted frequency the digital audio signals are fed into the memory, and then for further processing (10), and during the receipt of the other frequency output, signals from the memory are fed into the memory again, and on for further processing (10). Between the unaltered audio signal and the delayed audio signal a fade-out takes place. For Fourier analysis, a digital signal processor and for storage of the audio signal sections print-read memories are provided. A digital filter in the digital signal processor scans the spectrum of the audio signal by alteration of the filter coefficients according to the energy-richest components.     One of the delay devices (11, 12) is provided with a tapping device, which is connected to switches, via which audio signal sections reach a print-read memory. The switches are controlled by a micro-computer (4).

Patent DE-4209180-A1 (DE)
Title: Heavy metal recovery - by adding organic degrading reduction agent to contaminated watery waste, for redn. into free metal for physical sepn.
IPC: B09C1/02
Filed: 1992-03-20
Abstract: To recover heavy metals from watery media, the metal is reduced to free metal by organic degrading reaction agents. The metal is then sepd. from the liq. by physical means. The redn. agent is pref. a cpd. of the reductones such as ascorbic acid as a salt or derivative. Before adding the redn. agent, the watery soln. is set to a pH value of 10 +/-1, and neutralised after the metal has been removed. For the recovery of silver from waste, the silver metal formed is filtered out. For the extraction of mercury and other heavy metals from contaminated sludge or soil, water is added to form a viscous suspension, and the metals are removed by flotation. USE/ADVANTAGE - The method is for industrial waste and sludge, heavily contaminated with heavy metals. As the undesired heavy metals are generally in cationic form, they can be converted relatively easily into an electrically neutral metal state. In an example, a used fixing bath is mixed together with ascorbic acid as a redn. agent in a 10 m3 capacity mixer, in a ratio of 1:1, and set to a pH value of 10.5. After 24 hrs, the silver content of approx. 3200 mg/litre has dropped to a residual content of 5-10 mg/litre. With a ratio of 1:5, under the same conditions, the residual content of the same level is present after 1 hr of reaction time. The pptd. silver sludge is rinsed, filtered and dried. The filtrate, with a clear surplus of reaction agent is further processed. After 24 hrs. the required threshold of 1 mg AG per litre is not breached for indirect introduction. The filtrate is then neutralised and led away.

IPC: H05K1/05
Filed: 1992-07-31
Abstract: The add-on control device has a housing (16) open on one side which is attached to the housing block (10) of a hydraulic unit. In the housing (16) of the control device there is an electronic circuit, especially a final power stage, on a conductive film (26). The conductive film (26) is designed and constructed in such a way that direct contact with the connecting pins (22) of the magnetic valves (12) (consumers) and, at the same time, direct contact with the plug component (31) is possible. The conductive film (27) thereby acts as both the substrate for the circuit or circuit components (28) and a connection between the consumers (22) and the circuit or between the circuit and the plug component. The direct connection between the consumers (12) and the plug component (31) to the conductive film (26) eliminates the need for costly additional plug connections.
