Patent DE-3920590-A1 (DE)
Inventor: LAMY CHRISTOPHE DIPL ING
IPC: H04N9/00
Filed: 1989-06-23
Abstract: A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color sub-carrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color sub-carrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A sub-carrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence or absence of a color sub-carrier. A control unit initially causes the change-over switch ( 11) to be in the first position (a) and thereafter causes said change-over switch (11) to remain in the first position (a) if a color sub-carrier is present at the output (c) of the change-over switch (11), but causes the change-over switch (11) to be in the second position (b) if a color sub-carrier is not present. Once the change-over switch (11) is in the second position (b), the control unit (1) causes said change-over switch (11) to be switched back to said first position (a) from said second position (b) if a color sub-carrier is still not present.

Reduces errors caused by stray magnetic fields and increases torsion measurement accuracy.
Patent DE-3927681-A1 (DE)
Inventor: SCHMID BERNHARD
IPC: H04B3/04
Filed: 1989-08-22
Abstract: The method for intermediate amplification of digital signals with clock regeneration determines the phase difference between the reception timing signal and the local transmission timing signal and modifies the phase of the local transmission timing signal depending on the phase difference. It is particularly advantageous if the reception timing signal is used as the transmission timing signal as soon as the phase difference is essentially zero. It is possible as a result to minimise the start-up delay and also the packet spacing in that the number of bits which are to be temporarily stored can be kept down. Intermediate repeaters to carry out the method are indicated.

Title: Fault detector, using redundant signal emitter outputs - user to determines fault probabilities to eliminate stochastic faults
Inventor: KROGMANN UWE
IPC: G08B29/16
Filed: 1990-07-19
Abstract: A fault detector, for determining significant differences in the outputs from redundant signal emitters (10, 12), is fed with the output signal differences and provides a fault indication when the outputs correspond to a predetermined criterion which characterises a significant difference by a threshold value (T). The novelty is that, for obtaining a criterion for the presence of a significant difference which signals a fault, the detector (32) includes (a) a system (54, 64) for determining the probability, in a test interval, that the output difference is greater than the threshold value (T); and (b) a system (64, 68) for determining whether this probability exceeds a preset reference value (E), the fault indication being produced if this reference value is exceeded. The fig. shows a block diagram of the fault detector (32). USE/ADVANTAGE - The fault detector is useful in air transport, chemical process engineering, nuclear engineering and automation. It takes account of stochastic faults.

Title: Air heater unit - has axial ventilator by which quantities of air are blown through heating battery and mixed with cooler room air
Inventor: HILLE FRITZ DR ING
IPC: F24F13/08
Filed: 1990-12-05
Abstract: An air heater consists of an axial ventilator through which quantities of air are blown through a heater battery between parallel swivelling louvres. Flat bars are set on the face of the louvres in the form of a cross which split the air stream into four rectangular cross section separate currents. The flat bars (7) are bent at right angles at their ends to offset them a distance from the louvres. This prevents the warm air from discharging against the bars (7) and makes possible an uninterrupted secondary flow. USE/ADVANTAGE - The supply of cooler room air or secondary flow is increased in the warm air stream.

Patent DE-4103521-A1 (DE)
Inventor: CONEN DIETER
IPC: E05F1/10
Filed: 1991-02-06
Abstract: A stay for the bonnet (2) of a motor vehicle has two gas springs (6, 7), the first, (6), of which has a shorter travel than the second, (7), and its travel is such that it is fully extended when the bonnet (2) is in a first opening position. To take the bonnet (2) to a second position giving virtually free access to the engine compartment (1) it is necessary merely slightly to raise the bonnet (2) to overcome the static friction in the second gas spring (7) and the residual pressure in this gas spring is sufficient to open the bonnet (2) completely. This opening movement is not hampered by the first gas spring since on its cylinder (8) there is a movable casing tube (14) which provides the link between the first gas spring (6) and the hinge (13) on the bonnet (2).
