Title: Method for improving noise suppression in synchronous amplifiers or modulation amplifiers
Inventor: HELLER THEODOR DR
IPC: G01R29/26
Filed: 1983-12-15
Abstract: In order to improve the sensitivity threshold in the measurement of low signal voltages, in synchronous amplifiers or modulation amplifiers (or similarly used lock-in amplifiers) defined by the (narrowband) noise voltage lying within the effective bandwidth of the amplifier, the frequency and phase of the signal modulation and thus the frequency and phase of the reference voltage (as in German Patent Specification 2049844) of the noise voltage are re-adjusted in such a way that a 90 DEG  shift occurs in relation to the noise voltage phase. With the signal initially faded out, the instantaneous frequency (or phase) of the noise voltage is measured and monitored and, at the time when this frequency equals the mid-band frequency (or the differential quotient of the phase equals 0), the signal is faded in and the signal rise (i.e. the differential quotient of the signal voltage immediately following fade-in) is determined as a measure of the signal voltage.

Patent DE-3433208-A1 (DE)
Title: Hot water washing attachment for windscreens of motor vehicles of all kinds with front or underfloor engine
Inventor: GUTH RAINER
IPC: B60S1/48
Filed: 1984-09-10
Abstract: It is to be considered a problem that the windscreens of motor vehicles are affected by various weather conditions. For example summer weather often causes a high degree of soiling due to insects, especially on long journeys, in conjunction with residues of exhaust gases of motor vehicles travelling in front. A sudden necessary cleaning of the windscreen using the washing system which uses cold water does not provide immediate thorough cleaning; with hot water this process is carried out with substantially greater speed and thoroughness and ensures that the driver has good visibility more quickly and, as a result can, if required, considerably reduce the risk of an accident. The device is completely uncomplicated and its operation can be understood by virtually anyone. The owner of the motor vehicle can install it himself since no special technical abilities are required. For a low purchasing price, every motorist can make an additional contribution to traffic safety. Personally, I have had a prototype installed in my car for over a year and I am very satisfied with the performance of the device.

Patent DE-3434461-A1 (DE)
Title: Opto-electronic tool breakage monitoring
Inventor: BERGEN KARL-HEINZ DIPL ING
IPC: B23Q17/24
Filed: 1984-09-20
Abstract: Light barriers are usually used for tool breakage monitoring since a direct access to the tools is generally not possible. It is extremely difficult to accommodate these light barriers in the constricted area around the tools, and to adjust them, so that false indications during operation cannot be excluded. In addition, such known light barriers are expensive. To eliminate such false indications, an inexpensive small-volume device which is easy to assemble and to adjust is proposed, which consists of a reflected-light sensor which must be arranged in the vicinity of the tool to be monitored and supplies its signals to evaluating electronics via electrical lines or optical fibres. <IMAGE>
