Title: Multiple effect falling film evaporator - having flash cooling of forward fed liquor to acoid surface fouling
Inventor: BEHRENDT DIETER DIPL ING
IPC: B01D1/26
Filed: 1975-09-13
Abstract: Process for operating multiple falling film evaporator, particularly where there are high temp. difference between effects, using centrifugal separator to separate vapour from one section to heat the next, has the following characteristic: the separator belonging to the second effect is also fed with the stream of superheated liquid leaving the first effect. The expansion vapour and that coming from the second effect is then led directly to a condenser or to a third effect. The liquid from the second effect is either taken as product or flashed into the separator from the third effect. The principle can be extended to the number of effects required. For forward feed applications of falling film evaporators. Liquor distribution is an important feature of falling film evaporators whre there is a significant temp. and pressure difference between stages, flash evaporation occurs in the feed from one stage to the next. This gives distribution of the liquor over the tube bundle and also fouling of the lit-transfer surface. The system described overcomes this problem by flashing the feed in the separator before recycling the feed with some liquor from the effect. Cuts down time and reduces space requirements. The role of separator and flash vessel is combined.

Title: Power supply with pulse modulated control circuit - has voltage rectified via self inductor during switching phase of transistor
Inventor: ROSENTHAL HANS-DIETRICH
IPC: H02M3/335
Filed: 1976-05-07
Abstract: The mains connected supply system has a switching transistor and a control and regulating circuit which has a pulse width modulating stage which reacts to the ratio between the desired and actual value. It also contains an overload protection circuit which limits the switching transistor when a predetermined energy storage current is reached. This achievement is a voltage supply for a t.v. receiver. A voltage is rectified (27) via the self-induction of the power supply during the transmission phase of the switching transistor (6). This is used to generate the supply voltage for the remote control circuit (6). The circuit contains a resistance matrix in the pulse width modulation stage which produces a negative current to reduce the voltage of the remote control circuit.

Title: Computer aided radar tracking of several targets - using both position and velocity information on each target to provide almost fully automatic following
Inventor: MEYER RICHARD RUDOLF
IPC: G01S13/66
Filed: 1976-05-26
Abstract: A tracking method using an on-line computer facility to track one or several radar-detected targets is presented. Both position and velocity information is held by the computer for each target, and either one or several tracking stations can be used. In the case of one tracking station, a component of each target velocity can be stored, greatly reducing the search time required to find that same target on the next aerial traverse. Where two tracking stations are available each target velocity can be computed and stored, using a computer link between the stations, and the search can be further reduced. Almost no hand aiding or manual intervention is required with this system.
