Title: Low-temp. domestic baking oven - for gas firing with separate flue shaft and closed-loop hot air circulation
Inventor: WELCKER FRIEDRICH
IPC: F24C3/12
Filed: 1973-10-11
Abstract: The automatic temp. control range of a gas-fired domestic baking oven can be reduced to low temps. for defrosting and warming food by mixing the heating gas of the burner with room air by a blower. The gas/air mixt. which is controlled as a function of the baking oven temp. setting passes through a shaft subdivided from the baking oven. A separate radial-flow fan circulates through the baking oven the air which has been heated by contact with the hot shaft walls. This eliminates direct contact between the heating gases and food. The blower for room air can be omitted when the draught of the burner gases is adequate.

Title: Colour TV signal digital transmission system - colour difference signals are transmitted with reduced bandwidth
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N11/04
Filed: 1974-07-23
Abstract: When edges appear in the luminance signal, the colour difference edge steepness is increased during decoding. Colour difference signals are scanned during coding at a frequency lower than that theoretically required for scanning colour difference signals with the usual bandwidth. During decoding the mean value of each two consecutive scanned value is determined, and when an abrupt change occurs in the luminance signal, the last scanning or mean value is repeated and instead of the value following this abrupt change, the next-but-one scanning or mean value is inserted into the signal. The data flow necessary for the transmission of difference signals is reduced by about a half while maintaining the subjective impression of sharpness.

Patent DE-2516980-A1 (DE)
Title: Photo electric yarn break detector - which produces alarm with time delay when light beam is not interrupted over adjustable period
Inventor: JACOBI ERNST
IPC: D01H13/16
Filed: 1975-04-17
Abstract: A photoelectric detector of broken yarn or sliver in flyer or ring spinning machines of the textile industry directs a beam of light of smaller dia. than the yarn in the path of motion of each yarn between feed cylinders and flyers. The absence of a yarn produces a signal which is applied to a delay circuit to close an alarm circuit if the signal is maintained through a certain time interval. This has a more reliable action than conventional detectors, which sense the downfall of a broken yarn, crossing their path. False alarms by foreign bodies interrupting the beam of light are made ineffective. It pinpoints immediately the station where the yarn has broken.

Title: Liq. hydrogen rock melting equipment - has detonating gas flames of liq. hydrogen and oxygen directed at melting head against drilled and melted stone
Inventor: FOPPE WERNER
IPC: E21B7/14
Filed: 1975-12-02
Abstract: The excessive melted stone positioned in a ring gap produced by the melting drilling equipment is pressed in the surrounding stone. During continuous progress of the melting drilling the drilled hole is covered by a alyer of a solidified and in previous melted stone. The melting drilling equipment which receives its melting energy from liq hydrogen and oxygen discharges the energy necessary for melting the stone by one or more detonating gas flames in part of the melting head. By discharging the detonating gas flames directly against the melted stone a working temp of 3000 deg.C is achieved. This temp cannot be reached by an indirect melting method because the corrosion of the fire resistant material of the melting head would be too great.
