Patent DE-2440215-A1 (DE)
Title: Liquefaction of low-boiling gases - by partial liquefaction with mixed liquid coolant and further cooling with expanded gas coolant
Inventor: POCRNJA ANTON DIPL ING
IPC: F25J1/02
Filed: 1974-08-22
Abstract: Low boiling gases are liquified and further cooled by coolant circulated in multiple cycles, in which (A) cooling and at least partial liquefaction takes place by heat exchange with a liquid multi-component mixt., followed by (B) complete liquefactin and further cooling in heat exchange with an expanded gaseous coolant. Used in the liquefaction of natural gas supplies, esp. in base load plants. Plant is simplified and energy requirements reduced in comparison with known processes using initial cooling by a propane cycle followed by several multi-component cycles. Vaporisation of the multi-component mixt. occurs not at a fixed but at a sliding temp., which by choice of vaporisation pressure and compsn. allows the temp. range of vaporisation to be matched to the cooling curve of the gas. Temp. difference in heat exchange and hence energy losses, are low.

Patent DE-2518103-A1 (DE)
Title: Hydraulic circuit for hydrodynamic transmission - can selectively divert output from heat exchanger over dynamic brake
Inventor: KUGLER ARTUR
IPC: B60T1/087
Filed: 1975-04-23
Abstract: The hydrodynamic transmission has an oil pump (5) which pumps the oil through a heat exchanger and from there to the torque converter. If the vehicle is braked, a special hydrodynamic brake (10) is supplied with oil from the circuit via a supply valve (11) and a brake control valve (12). For improved cooling the oil is taken from the output of the heat exchanger (8) so that the cool oil is driven under pressure through the brake. The heat exchanger thus caters for both circuits, with the torque converter demands dropping during braking. The heat exchanger is kept compact with a pressurised cooling circuit.

Patent DE-2529944-A1 (DE)
Title: Additional protection for automatic synchroniser circuits - is to guard against switching due to transient disturbances
Inventor: BORN ECKHARD DIPL PHYS
IPC: H02J3/40
Filed: 1975-07-02
Abstract: The circuit comprises additional logic elements connected to both the incoming and system voltage which form a channel generating a triangular waveform which is 180 deg. displaced from the existing channel. Both channels are fed directly and via a differentiator to separate level detectors which then combine to determine if a closing signal may be given. The voltages are the combination of the triangular voltages and their differentials. A disturbance at time may reach the threshold trigger value indicating that the voltage levels are correct for closing. However the other channel has a threshold value on zero, and, as the disturbance is in the same direction on both channels the close signal is vetoed and false operation avoided.

Patent DE-2549311-A1 (DE)
Title: Separator for isotope mixts. - using ionic charge interchange to preferentially charge one of the isotopes
IPC: B01D59/34
Filed: 1975-11-04
Abstract: Process uses a charge transfer reaction (A++B right arrow A+B+). The atomic ions A+ of one of the isotopes are formed preferentially by irradiation while the other isotope is not affected. The charged ions are then neutralised by atoms or molecules (B). Alternatively the atoms of one of the isotopes are activated by irradiation while the other remains qinescent. The activated one then reacts with ionic stream of atoms or molecules (B+). A and B are different elements or cpds. To select a suitable material for B, its first I.P. should be greater than the first I.P. of V. If the B+ system is used, its first I.P. should be less than the first I.P. of V. Used esp. for separating the isotopes of V to provide an enriched fuel for nuclear fuels. The process proceeds with the same probability as the excitation of the particles from their basic state. The transfer probability of the various excitation stages are differentiated by several orders of magnitude. Also ions are used instead of atoms, which permits acceleration, deflection, etc. Only a single resonance light source need be used.
