Patent DE-2363482-A1 (DE)
Title: Testing liquid transporting inclined conduits for leaks - is by closing ends and observing level relative to temperature and time
Inventor: BEUTH PAUL DIPL ING
IPC: G01M3/28
Filed: 1973-12-20
Abstract: In the process for testing inclined conduit pipes, used for transporting liquids, in respect of leaks, the pipe is first closed off at both ends by gate valves. The temperature is measured at various points along its length by resistance thermometers. Near to the upper end of the conduit pipe, two impulse ducts are connected, with lead to a pressure difference transmitter (Pd). The latter and the thermometers are connected to a mini-computer which formulates automatically the difference between the registered volume of liquid in the conduit and the theroretical volume depending on temperature. An alarm connected to the multi-computer is released if the difference exceeds zero or a given amount.

Title: Noise suppression cct. for radio LF signals - has dynamic limiter and regulator with feedback to op. amp. at limiter input
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H03G3/34
Filed: 1974-02-27
Abstract: The noise suppression circuit, for LF signals in radio receivers, has a dynamic limiter in the path of the signal which limits the amplitude of signal components with sudden spikes. The limited signal is coupled back to the non-inverting input of an operational amplifier at the limiter's input. A regulating stage is connected after the limiter and reduces signals that fall within its regulating range by amounts proportional to the amplitude of the operational amplifier's output, i.e. the lower the output, the greater the reduction. Several limiters with different time constants may be connected together in a chain.

Title: Anti-dazzle rear view mirror - with liquid crystal layer in mirror sandwich coupled to light detector
Inventor: POKOWITZ WOLF-DIETER ING GRAD
IPC: G02F1/13
Filed: 1974-04-03
Abstract: The light falling on the rear view mirror is monitored by a photosensitive circuit coupled to an impulse generator. The amplitude of the signal generator is dependant on the intensity of the incident light. The mirror is covered by a second glass layer with a liquid crystal layer between them. The inside faces of the glass plates are coated with a transparent, electrically conducting layer with the layers connected to the outputs of the impulse generator. The transparency of the rear view mirror is then set to change gradually with increasing incident light. The system is thus more versatile than the mechanically dipping systems.

Title: Illuminated push-button for communications equipment - has light emitting diode as signalling light
Inventor: BURGER GEORG
IPC: H01H13/83
Filed: 1974-08-08
Abstract: The light emitting diode (3) is mounted on the push-button front edge, protruding obliquely forwards. The 1.e.d. (3) is mounted in a recess (4) partly covered by a marking plate (5) also with a recess (6, 7). The push-button surface (5) is slightly inclined backwards. This arrangement exploits the given daylight or the artificial lighting of the room containing the apparatus to enhance the total brightness without increasing the undesirable generation of heat. Confusing reflection effects are also avoided. The signal lamps can be safely brought directly to the button surface since 1.e.d.'s are insensitive to direct thrusts. Variations in light intensity can thereby avoided.

Title: Differentiation of hepato- and cardio-specific lactate dehydrogenase - in serum by selectively inhibiting the hepatospecific enzyme with heavey metal salts
Inventor: SCHMIDT KARLHEINZ DR MED DR RE
IPC: C12Q1/32
Filed: 1975-03-26
Abstract: In differentiating the hepato- and cardio-specific lactate dehydrogenase in blood serum, a heavy metal salt soln. (e.g. AgNO3 soln.) is added to the blood serum and the non-inhibited (i.e. cardiospecific) LDH is subsequently determined using a conventional procedure. Organ-specific diagnosis of diseases associated with an increase in blood LDH activity. Differentiation of cardiac and hepatic disorders is of clinical importance. The procedure permits the two LDH isoenzymes to be differentiated using conventional automatic analysers. The only step required in addition to conventional determinations of LDH is the addition of the heavy metal salt.
