Title: Heating injection or pressure casting mould - using vapour circuit separated from cooling circuit operation with liquid esp. water
Inventor: KIENLE HEINZ
IPC: B29C33/04
Filed: 1978-01-20
Abstract: A method of temp.-controlling, esp. heating up moulds, specifically pressure-casting or injection moulds, utilises a heating circuit in which the flowing medium is in the form of a gas or vapour, more specifically steam, ethyl alcohol or a vapour mixture of water and alcohol. The steam may be saturated or superheated. In a preferred embodiment, there is a heating circuit in which the gas or vapour flows and a separate cooling circuit through which a liquid coolant, eg. water, flows. By using a gas instead of a conventional liquid, such as oil, for providing the heat much higher flow rates and consequently a much higher supply of heat can be achieved. The method is eminently suitable for industrial use and is simple and economic to operate.

The addn. improves the repeatability of the interval between the positions of the leading edges of successive portions of the tubular film.
Patent DE-2919620-A1 (DE)
Title: Noise pulse counting in band limited transfer system - using automatically-varied measurement of sampling time to suppress multiple detections
Inventor: MARTIN DETLEF ING GRAD
IPC: G01R29/027
Filed: 1979-05-16
Abstract: An arrangement counting noise pulses in band-limited transfer systems employs a variable measurement inactive time to reduce multiple detections caused by noise pulse-induced damped oscillations. The measurement inactive time is automatically adjusted to its optimum value dependent on the channel characteristics, magnitude of the impulse being measured, and the adjusted measurement level. This is achieved without variation to the measured result time distribution. Two threshold switches in the noise impulse counter initiate the measurement inactive time when the damped oscillation voltage first exceeds both threshold voltages. The measurement inactive time is terminated when the lower threshold voltage is again exceeded by the damped oscillation voltage. The higher threshold voltage is variable to enable noise pulse selection sensitivity adjustment.

Patent DE-2921831-A1 (DE)
Title: Multichannel AF amplifier with class B output stages - to which power supply is switched off when there is no input signal
Inventor: MONDORF HELMUT
IPC: H03F1/30
Filed: 1979-05-29
Abstract: The circuit is applicable to high quality audio amplifiers. It switches off the final amplification stages of a three channel power amplifier. The stages each handle different parts of the auido frequency spectrum. The final stage is a class B amplifier fed from a quasi class A amplifier stage which remains energised continuously as it has a very low quiescent current drain. The power stage is switched automatically when there is no input signal to the equipment. The output of the signal source, for example a tape deck or radio tuner, is applied to a voltage divider and a tapping applies part of the signal to an amplifier driving a relay coil. The relay contacts are in the primary circuit of the power supply transformer for the final stage. With no signal the transformer is off and thus gives a considerable power saving. The power supply for the preamplifier and intermediate stages is taken from a separate transformer which remains energised. Automatic switch off on cessation of signal is time delayed to prevent undesirable interruptions.
