Patent DE-2142134-A1 (DE)
Title: Fractionation plant - for natural fatty-acids and their esters based on cooling by evaporation of solvent
Inventor: LAU JUERGEN
IPC: C07C51/48
Filed: 1971-08-23
Abstract: The substances to be fractionated are dissolved esp in hexane and separation of the various components takes place as a result of the cooling produced by evaporation of the solvent, at least partially, in vacuum applied to the main fractionation vessel, or mutli-floor column, via a regulator valve, the solvent being recovered from other gases by fractional condensation. The resultant mixture in its cooled state is passed first through a filter to separate out the solidified components, the residual filtrate being collected and fed back to the fractionation vessel by a pump as required. Significantly faster and cheaper in terms of power requirements than direct cooling methods reduced risk of fermentation etc.

Title: Pivotable jet especially for rocket propulsion - has outer casing of super hard material with inner casing of heat resisting material
Inventor: BIEMOLD WILHELM
IPC: F02K9/84

Patent DE-2364449-A1 (DE)
Title: Conversion of pulse train frequency into digital numerical values - involves derivation of signals from pulses of frequency train
Inventor: SEELIG ANTON
IPC: G01R23/02
Filed: 1973-12-24
Abstract: A synchronising stage is controlled by the pulses of the frequency train and by a timing generator producing a timed pattern. The synchronising stage forms from the pulses signals which simultaneously reach a shift register and a logic circuit. When signals of a particular timed sequence appear at the shift register and logic circuit, they enter the shift register and further signals are produced at the logic circuit output. These signals modulate a forward-reverse counter in the forward direction. The signals sent through the shift register are conveyed to another logic circuit and the signals appearing at the output of this circuit modulate the counter in the reverse direction.

Patent DE-2427419-A1 (DE)
Title: Protection for power transistor with HF output - to prevent damage due to sudden load mismatching involves second regulating loop
Inventor: KLEISCHE WILHELM
IPC: H02H7/20
Filed: 1974-06-05
Abstract: The application is to high frequency circuits, typically transmitters, where a load mismatch, for example due to failure in an aerial lead, can cuase an excessive overload which may destroy the active output elements. A second regulating loop (10, 11, 12, 3) is added to the circuit which gives rapid amplification of the mismatch error and applies this to a blocking element (3) in the main circuit input. This blocking signal is produced in a short time rated integrating circuit. During the integrating time a further signal is passed to the control elements (9, 8) of the main loop to give the effect of a large error and thus to turn off the output stage.

Title: Trailer air brake with electric control - using non delay electric connection between unit and trailer
Inventor: WEDEMEYER ERNST AUGUST DIPL IN
IPC: B60T13/66
Filed: 1974-07-11
Abstract: The towing unit is fitted with a simple, membrane operated pressure switch in its pneumatic brake line. This is operated by braking pressure pulses. The switch is connected electrically to a servo on the trailer, which operates a simple solenoid valve to connect the trailer brakes to a pressure reservoir. The system ensures a rapid application of the trailer brakes, with no delay due to pressure lag in the connecting pipes between unit and trailer. The pressure switch can be replaced by a switch operated by the brake pedal, which ensures tha the trailer brakes are applied slightly before the unit brakes, to prevent the trailer from slewing.

Patent DE-2510766-A1 (DE)
Inventor: KORTLANG WOLFGANG
IPC: H03K23/66
Filed: 1975-03-12
Abstract: For automatic digital division of a frequency, particularly for telemetry of tachometer transmissions, with a division ratio which is expressed by a number of the form a + n x 10<-m>, e.g. 26.475 = 26 + 475 . 10<-3>, the frequency is input to a frequency divider (Fl), which can be switched between a:1 and (a + 1):1, and during 10<m> output periods the frequency divider is switched by the output frequency n times to (a + 1):1 and (10<m> - n) times to a:1. An advantage is that the frequency divider (Fl) is switched using:     . decade counters [Zm, Z(m - 1), Z(m - 2)] . decoders or comparators [Vm, Vm0, V(m - 1), V(m - 1)0, V(m - 2), V(m . 2)0], which can be adjusted to the desired switching interval, and are connected in series after the decade counters   . digital logic elements (A1, A2)   . at least one low-inertia changeover switch (U). Telemetry can thus be carried out in a digital rather than analog way, and the efficiency and security from interference are considerably improved. <IMAGE>
