Patent DE-2819760-A1 (DE)
Inventor: LAESSER CLAUDE
IPC: G04C10/04
Filed: 1978-05-03
Abstract: An electronic timepiece indicates a change in one of the working parameters of the timepiece, such as the battery nearing its end of life, by changing a rest position of a user viewable indicating member. The timepiece includes a stepping motor driven by drive pulses produced from a timebase. The indicating member is rotated a certain amount by each step of the stepping motor and has two rest positions. The first indicates no change in the working parameter and the second indicates a change in the working parameter. The indicating member normally stops in the first rest position. A circuit responsive to a change in the working parameter causes an additional drive pulse to be applied to the motor, changing the normal stopping of the indicating member to the second rest position to indicate the changed working parameter.

Patent DE-2834300-A1 (DE)
Title: Air circulation baking oven - with heat exchanger for flue gases and primary air
Inventor: SCHWENK LUDWIG
IPC: A21B3/00
Filed: 1978-08-04
Abstract: A first heat exchanger is heated by the flame of a burner and a second heat exchanger is traversed by the flue gas and is used to preheat the primary air for the burner. This eliminates the frequent disagreement between supply and demand of heat which occurs with the conventional heat recovery from the flue gases by water heating. Two fans circulate hot air through the baking space and around a combustion chamber on top of the oven. Primary air for the burner, supplied by a blower, passes around the second heat exchanger; additional air bypasses the heat exchanger through a duct to keep the burner head cool.
Patent DE-2836280-A1 (DE)
Title: Photoelectric inspection of textile material - by transverse light-scanning non-parallel to the weft direction
Inventor: SICK ERWIN
IPC: D06H3/08
Filed: 1978-08-18
Abstract: A photo-electric inspection device for woven or knitted material in which a spot of light scans the fabric at an angle to the weft, or course, direction of 10-30 degrees and light-sensitive receivers above and below the fabric monitor the reflected and transmitted radiation. A series of rollers or guide surfaces set parallel to the scanning direction eliminate creases and distortion in the fabric, and raises it slightly out of the plane of the undisturbed running fabric to give a taut, flat surface for the scanning beam. Relatively minor faults can be detected by this method which would be swamped by the variations due solely to the structure of the material if the scanning direction were parallel to the weft, or to the courses of knitted fabric.

Title: Opto-electronic relay for telephone exchange - has HV breakdown to accommodate large amplitude ringing signal voltages
Inventor: EMDE KURT LOTHAR DIPL ING
IPC: H03K17/795
Filed: 1979-03-20
Abstract: The optoelectronic relay has a light emitting diode irradiating a phototransistor coupled between the bases of two complementary push-pull transistors. Resistors connect the bases of the transistors to their respective collectors. Alternatively, the phototransistor may be connected between the emitters of two complementary transistors via a third transistor. In this case the bases of the two transistors are coupled by a resistor. Resistors also connect the bases to the respective collectors as before. The circuit may have various degrees of complexity. The advantage lies in the high voltage breakdown (e.g. several 100V) and can therefore handle the large ringing voltage amplitudes experienced in a telephone exchange.
Patent DE-2911916-A1 (DE)
