Title: Weight sensor power supply for moving material - has trapezoidal waveform processing circuitry and provides signals proportional to weight and speed of flow of material
IPC: G01D5/14
Filed: 1978-11-22
Abstract: The weight sensor circuit has a square wave generator which supplies a sawtooth generator whose output is limited. A power circuit is used to drive the weight sensors. The sawtooth generator also drives a threshold circuit whose valve is compared with a reference voltage. The threshold circuit output controls analogue gating circuits. The power circuit is also connected via an impedance matching circuit and gate to a memory whose output is proportional to the speed of the conveyor. A comparator connected to the memory output controls the square wave generator. The sensor output is connected via an impedance matching circuit and gate to a memory to provide a dc output signal proportional to speed and weight of material flow. The arrangement avoids complex transformation and rectification of an AC signal.

Title: Time-dependent measuring instrument with max. and min. indication - has recording indicators whose movements in opposite direction are hampered by releasable friction
IPC: G01D13/24
Filed: 1980-01-03
Abstract: The time dependent measuring instrument is required not only to indicate the instantaneous value of a magnitude but also to record the highest and the lowest values attained during a preset time interval. Thus, it may record, or store, magnitudes such as temp., pressure, humidity, mains voltage, liq. level, or speed, as well as to indicate them on a scale as required. The instrument has a main indicator moving along a scale in dependence on changes in the measured magnitude, and at least one recording indicator (4, 5) rotatable about the same axis as the main indicator in relation to the scale, its movement being dependent on that of the main indicator. The movement of each recording indicator in the opposite direction is blocked by a device generating frictional forces. This device is releasable so that each recording indicator may move under a resetting force.

Title: Temp. stabilisation system for radiation detector assembly - has cooler for removing heat from pipe enclosing detector assembly whenever pipe temp. exceeds predetermined level
Inventor: RICHTER ALBERT PAUL JR
IPC: G05D23/24
Filed: 1980-02-08
Abstract: The system stabilisation system comprises a heat pipe enclosing the radiation detector assembly and is positioned in a dewar flask. A thermo-electric cooler is joined to one end of the heat pipe. The heat exhaust of the thermo-electric cooler is communicated to a heat dissipation device in the form of a fin assembly. A thermistor senses the temperature at the heat pipe. When the thermistor indicates a temperature in excess of that corresponding to a reference signal, a control signal is produced by a control device to cause a power source to operate the thermo-electric cooler to remove heat from the heat pipe to the fin assembly. The vacuum within the dewar flask effectively limits the environmental heat passing to the heat pipe to radiant heat.
