Title: Metering device for liq. - uses hydraulic fluid expanding bellows pump under control of stroke generator, and ejecting measured quantity of liq.
Inventor: STEINORT HANS
IPC: F04B43/113
Filed: 1979-05-14
Abstract: The metering device is intended for proportioning chemicals into large washing machine. It has a compressor pump of given volume controlled by a stroke generator defining a given number of strokes. The pump comprises a bellows arrangement acted on by a spring (4) at one end and resting against a fixed surface at the other one. A hydraulic fluid is pumped into the bellows via a standpipe lying along the axis of the bellows. The hydraulic fluid enters the bellows through holes at the top of the pipe and expands the bellows against the action of the spring. The liquid being metered occupies the space around the bellows inside an outer casing (1) and is forced out of the casing when the bellows expands due to an increase in the pressure of the hydraulic fluid. The stroke generator, with one or several coding program switches, defines the number of strokes of the bellows and accordingly controls a valve (3) that admits the hydraulic fluid to the bellows.

The inner is then soldered (16) to the wire, the wire cut to length and the plug fitted. This method facilitates production of connectors with standard length and capacitance, despite large variations of cable capacitance per unit length.
Patent DE-2937986-A1 (DE)
Title: Speech level control for FM transmitter - has limiting clipper which prevents clipping of frequencies below one KHz by use of constant gain amplifier
Inventor: FOSSLER HEINRICH
IPC: H04B1/62
Filed: 1979-09-20
Abstract: A speech modulated FM transmitter has 6dB oer octave pre-emphasis over the range 300 to 3000Hz (1), followed by a clipper which limits peak frequency deviation to 4kHz. Severe distortion results from soeaking too loudly, particularly if clipping occurs on frequencies below 1000Hz. because the third harmonic is then in the audio pass band. Distortion is reduced by inserting a gain-controlled amplifier between the microphone and the pre-emphasis circuit. With increasing speech level, the gain remains constant until frequency components at 1000Hz reach the clipping level. Further increase in speech level reduces the gain progressively. This ensures that frequencies below 1000Hz are not cliooed (11).
