Patent DE-3531681-A1 (DE)
Inventor: HOFMANN OTTO DR ING
IPC: G01C11/02
Filed: 1985-09-05
Abstract: The process as described serves to determine the trajectory of a missile by means of observation stations which are quasi-stationary or move above the surface of the earth. For this purpose, multiline, opto-electronic or opto-mechanical scanning cameras are used. The passages of the lines of the missile image are recorded as a function of time and of the image co-ordinates. Co-linearity equation pairs are established which contain the known orientation parameters of the observation station, as well as the possibly approximate data for the trajectory of the missile, and from these, the image co-ordinates are calculated. On the basis of the latter and the measured image co-ordinates, error equations are prepared. A compensation method and an iterative process enable the most probable values to be obtained for the missile trajectory parameters sought.

Title: Process for the further processing of raw sludge taken off from a biological waste water (effluent) purification plant
Inventor: BOEHNKE BOTHO PROF DR ING
IPC: C02F3/28
Filed: 1985-09-27
Abstract: Process for the further processing of raw sludge taken off from a biological waste water purification plant to give, on the one hand, digestion gas and, on the other hand, a landfillable and/or utilisable product in a biological sludge treatment plant having a first anaerobic treatment stage operated as an acidification stage and a second anaerobic treatment stage operated as a methanation stage. The acidification and methanation are carried out in structurally separate plant sections each having downstream, covered and insulated settling tanks for external biomass retention. The return sludge circulations are separate and the cultivation and enrichment of support-immobilised biomasses is carried out in independent reactors. The raw sludge to be introduced into the acidification stage is adjusted by thickening and/or decanting to a dry matter content of 5 to 12%, preferably about 9%. In the acidification stage and in the methanation stage, biomass return is carried out. Because of the very different residence times in the acidification reactor and methanation reactor, different biocoenoses can be cultured and optimal environmental conditions can be employed. A plant for carrying out the process is depicted below (Fig. 1). An extension of the plant by additional internal biomass circulation is likewise depicted below. <IMAGE>

Title: Mat for the controlled release of substances, and method for making it
Inventor: BRATITCH EDUARD
IPC: B65D81/28
Filed: 1985-10-04
Abstract: Method for the qualitative and quantitative control of the release, either by heating or without heating, of a scent, deodorant, insecticide, insect repellent, mothproofing agent, disinfectant, pesticide and other substances which are imbibed in an inert mat, is described, and also the application of this method in making suitable mats (1) for use in practice. Such a mat (1) is wholly or partially coated either on the upper surface or on the lower surface or on both surfaces, in particular on the upper surface, with a thin metal foil (2) or another non-porous, impermeable, compact material, and is coated on the lower surface with a thin ply (3) of heat-insulating material or on the upper and lower surfaces with a metal foil etc. or a heat-insulating material. By incision and removal of a part of the surface of these additional coatings, the desired release rate of the active material, with which the mat (1) is imbibed, can be achieved. The preference for one or other method depends on the volatility of the active substance, on the temperature of the implement, etc. The mats (1) can be heated in small electrical appliances, or the release of the active substance can take place without heating and with the use of natural or artificial methods. <IMAGE>

Title: Filter for precipitating solid particles of gaseous or liquid media
Inventor: HERDING WALTER
IPC: B01D46/00
Filed: 1985-12-16
Abstract: The known filters which work according to the deep-bed filtration principle have the drawback that their filter resistance increases the longer they are used. On the basis of a filter operating according to the principle of surface filtration, constant efficiency is ensured by the foreign particles being deposited on a low-friction, non-hygroscopic, temperature-stable surface (5) not penetrating the interior of the filter element (3). Whenever fouling has reached an appropriate level, the filter element can be cleaned in a simple manner by the blow-back method. <IMAGE>

Title: Circuit arrangement for demodulating RF signals
Inventor: ZUCKER FRIEDHELM
IPC: H03D3/24
Filed: 1986-02-20
Abstract: In two circuit arrangements for demodulating RF signals which are supplied to one input of a mixer M, the output of the mixer M is connected to the input of a narrow-band band-pass filter B. In one circuit arrangement, the output of the band-pass filter B is connected to the phase detector PD of a PLL circuit, the voltage-controlled oscillator VCO of which is connected to the other input of the mixer M. The demodulated output signal can be picked up at the output of the low-pass filter TP of the PLL circuit. In the other circuit arrangement, the output of the band-pass filter B is connected to the input of a demodulator D, the output of which is connected to the input of a voltage-controlled oscillator VCO. The output of the voltage-controlled oscillator VCO is connected to the other input of the mixer M. Because the frequency f2 at the output of the mixer M is controlled to a constant value by the voltage-controlled oscillator VCO in both circuits, a band-pass filter with a very narrow bandwidth can be used. The narrower the bandwidth of the band-pass filter, the better will be the signal/noise ratio. <IMAGE>

Title: Method for improving the economic efficiency of operating pressure booster facilities and the like
Inventor: BOHN HEINZ DIPL PHYS
IPC: F04D15/02
Filed: 1987-06-19
Abstract: The invention concerns a method for improving the economic efficiency of operating pressure booster facilities and the like with a preset pressure setpoint, in which the pumps are driven by electric motors with speed controllers such as frequency converters or similar devices. Its purpose is not only to save energy in operating the pump, but also to achieve a simplification compared to facilities without speed controllers (but with minimum pressure fluctuations) by enabling smaller buffer tanks that require less space to be used. The invention proposes that for this purpose, for delivery rates or liquid withdrawal from pressure booster facilities in the range of the desired withdrawal or above, the pump be operated in a steady state in the range of maximum pump efficiency at rated speed, while for delivery rates or liquid withdrawal from pressure booster facilities below the desired withdrawal, the pumps be operated in a non-steady state, alternating between operation in the range of maximum pump efficiency at rated speed and operation at minimum speed and minimum energy consumption (Fig.). <IMAGE>
