Title: Container filling machine valve system - has alternate switching of monitor air for fill check and sensor cleaning blowout air
Inventor: TRUSSELLE WILLIAM HENRY
IPC: B67C3/28
Filed: 1973-11-26
Abstract: The pneumatic control system is for container filling machines fitted with heads held in set relation to the container during valve controlled filling operations. The fill valve is opened via a valve operated supply line for compressed air, and the container level is scanned by a sensor tube connected to a pressure monitor line so that, when the fill level is reached, the monitor responds to back pressure by closing the fill valve via this supply line valve. A switching valve in the air supply line and in the monitor line admits pressure alternately to the pressure monitor line and to a blow-out line, used to clear the sensor tube. The valves forming the switching valve unit together with a valve in the blow-out line are held by springs in a first setting to admit monitoring air to the sensor tube until reversed by an additional valve, when the fill valve closes and so switches to the second setting to feed the blow-out air to the sensor tube. One of the switching valves has a relatively stronger opposing spring so that one valve in this unit is always switched over before the valve mounted in front has cleared the way for the blow-out air into the sensor tube.

Patent DE-2436367-A1 (DE)
Title: Generator with decadal frequency setting - has an electronically tuned oscillator and an analogue phase meter
Inventor: HARZER PETER DIPL ING
IPC: H03L7/185
Filed: 1974-07-27
Abstract: The phase meter supplies the oscillator control voltage. A standard pulse voltage and a pulse voltage derived by frequency division from the oscillator output are applied to it. A pulse weighting device is inserted between the oscillator and the first frequency division stage. Control pulses are applied to it in order to set the oscillator frequency, so that for each received control pulse it either suppresses from or adds an additional pulse to the pulses delivered from the oscillator to the frequency divider. Pulses which are not harmonics of a standard frequency, can also be applied to the pulse weighting device through a pulse store from which they are read out, or through an anticoincidence circuit. Interference voltage, which then appears at the phase meter output (control voltage fluctuation) is thus suppressed.
