Title: Flow resistance measurement of porous plates - by applying suction cowl surrounded by another suction cowl
Inventor: NEUHAUS WULFDIETER ING GRAD
IPC: G01N15/08
Filed: 1978-11-06
Abstract: The resistance to flow of porous plates which are used for the aeration in storage and drying operations of pneumatic transport, mixing and bunkering and which may be made of sintered metal, ceramics or porous polyethylene is determined by applying a cowl with a seal. A vacuum is applied to this cowl, and the flow rate and pressure are measured while a second cowl surrounding the first is also kept at a negative pressure. A porous polyethylene plate is tested by applying an inner cowl and an outer cowl to it. A blower draws air through the plate at a rate of 400 m3 per m2 and h. A flow meter indicates the flow rate and a vacuum gauge shows the negative pressure which, in the case of polyethylene, will lie between -50 and -1000 mm w.g. This device is simple and can be manufactured at low cost. It is easy to handle and furnished reliable results.

Patent DE-2854352-A1 (DE)
Title: Pulse generator with rotary tuner - uses tachometer, voltage to frequency converter and counter to convert setting into control signal for tunable oscillator
Inventor: STIEPER BRUNO
IPC: H03J1/22
Filed: 1978-12-15
Abstract: The pulse generator has a tachometer (1) acting as a d.c. voltage source coupled to the input of a voltage to frequency converter (2). A comparator (3) compares the tachometer's output with a reference and produces a signal that determines whether a counter (4) counts up or down. The counter counts the output of the converter and controls the tuning of an oscillator. The converter's characteristics exhibit an over-proportional rise in pulse frequency with d.c. input voltage. The tachometer is coupled to a rotary tuning knob so that the latter's position is translated by the generator into a control signal for the tunable oscillator. The control knob does not need returning to its original position again after tuning has been set.
