Title: Fuel injection system for IC engine - has electromagnetic control elements feeding fuel from common chamber to individual nozzle
Inventor: SCHAFFITZ WOLFGANG DR ING
IPC: F02M61/16
Filed: 1979-02-24
Abstract: The fuel injection system has the entire quantity of fuel injected through the nozzles conveyed by a continuously-operating, fuel metering pump into a pressure chamber shared by all engine cylinders. From this pressure chamber the fuel is conveyed via electromagnetic control elements to the individual injection nozzles associated one with each cylinder. The phase and duration of the injection is controlled by electromagnetic pulses synchronised to the engine's shaft. The fuel pump is driven by the engine at a constant speed ratio. The quantity of fuel conveyed per unit time is proportional to the engine speed and to a variable dependent on the pump's setting.

Title: Fluid mass throughput measurement independent of flow structure - determining pressure drop across auxiliary flow intersection point
Inventor: TETEREVJATNIKOV LEV NIKOLAEVIT
IPC: G01F1/78
Filed: 1979-03-30
Abstract: A mAterial mass throughput measuring method is applicable to fluid flows and involves measurement of a pressure drop between two points using a subsidiary material flow. The relationship between the throughput and pressure drop is independent of the flow structure, exhibits a mass characteristic, and is linear over a wide range of variations. The pressure drop in the flow being measured is determined between points both sides of the point at which the measurement flow is intersected by an auxiliary flow of speed, v, in a channel of cross-sectional dimensions, h&b. The main flow cross-sectional dimensions and speed are H, B and V, where V corresponds to max. throughput. The relationship between these variables defining the auxiliary flow is v > H/h b >= B.

Title: Varying centrifugal filter drum acceleration - forms filter layer and breaks down layer for cleaning component pieces
Inventor: HOFFMANN ERNST H DIPL ING
IPC: B01D33/00
Filed: 1980-09-05
Abstract: In the horizontal drum of a centrifugal filter using a filter layer of separate pieces, the initial formation of the layer and its reformation after washing are effected by controlled rotary spinning rates. When the pieces, which may be granular solids or thin fabric portions, are inserted, the drum is gradually accelerated to a radial acceleration of 0.8-1.1 g producing a uniform layer for subsequent filtering at faster rates. After filtering this acceleration is reduced to 0.2-0.9 g, the filter layer breaks up and is washed by added fluid, after which the drum is speeded up to the initial layer-forming rate. For fabric filter pieces the washing fluid depth should not exceed 30% of drum dia. The appts. is also claimed. Cleaning is more effective than known spraying of drum exterior or extn. of filter layer for cleaning in separate vessel.
Patent DE-3036239-A1 (DE)
Title: Synchronising circuit for short-wave radio links - eliminates echo interference due to multipath propagation by employing synchronisation in two steps
Inventor: BURGER ERICH ING GRAD
IPC: H04B1/713
Filed: 1980-09-25
Abstract: The synchronising circuit has interference due to multipath propagation reduced by selecting the frequency changeover period to be smaller than the time between echos. The receiver is thereby synchronised in coarse terms from the incoming modulated data signal by evaluating a signal track relating to carrier-wave for track phasing in conjunction with a comparison of each carrier-related signal track with an associated reference signal generated at the receiver. Fine synchronisation is accomplished using control signals derived from the passages through zero of the demodulated data signal.

Information additional to that concerning the dispersion factors by use of the central component of the ultraviolet light and concerns the sample tissue density. The diagnosis is then based upon the relationship between the dispersion factors and the density parameter dependant on the type of tissue The density signal is that of the detector at zero degrees angular position. The ratio is formed of the amplified zero degree detector signal and a reference signal obtained from the ultra violet source light amplified according to a calibration procedure.
Patent DE-3037803-A1 (DE)
Title: Automatic selection of special services - connecting telephone subscriber to electronic exchange by information previously stored by subscriber by special key selection
Inventor: BACKHAUS MARTIN DIPL ING
IPC: H04Q3/545
Filed: 1980-10-07
Abstract: The objective of the modified branch exchange circuitry is to make special facility connection frequency used easier to access by the subscriber. Examples are the storage of frequently called numbers, the selection of particular call rerouting, or the setting up of regularly used conference circuits. The exchange principally contains a control unit, an evaluator and coordinator with read-write memory. With these are the necessary peripheral logic circuits. Lifting the receiver transmits to the exchange a start and extension number signal. If an extension number is then keyed in from the telephone unit action in the exchange is normal. If, however, two special keys are pressed in succession, for instance, and one of four 'others,' the processor at the exchange opens a route to the memory. An instruction can then be entered in a place referenced by the extension number. For future use then only the combination of special keys need be pressed to obtain the entered service.
