Title: Vehicle fuel flow meter - produces digital output by counting passage of small turbine blades past pick-off head
Inventor: AUGUST PAUL DIPL ING DR
IPC: G01F1/075
Filed: 1974-08-21
Abstract: Small flow meter is compact and is, to a large extent, independent of vlotage and temperature variations. It consists basically of a small turbine wheel arrangement mounted in a flat cylindrical casing, with an inlet (2) and outlet (3) running into and out of the curved surfaces so that the fuel impinges briefly on the blades of the wheel. At the tip of each blade is mounted a small magnetic element (17) which actually touches a series of probes (21) mounted in the chassis so that a deflection of the blade occurs. A pickoff coil (19) is wound round each probe and the pulse detected by this each time a blade passes a probe is passed to a common circuit consisting typically of an integrator arrangement incorporating a linear amplifier (IC). An accurate readout can thus be obtained.

Title: Transfer sheet or tape for direct electrostatic recording - with low conversion energy and static rupture voltage
Inventor: ANTON RAINER DIPL PHYS
IPC: B41M5/20
Filed: 1975-03-29
Abstract: Transfer agent, esp. sheet or tape, is used in a direct electrostatic recording process, esp. as in DT 2561016, in which a number of ruptures is released between the electrode(s) and an earthed grid electrode in the colour carrier, developed as dielectric with low dielectric strength, by passing below electrode(s) by pressing the dielectric briefly across these electrodes with a voltage amounting to a multiple of the static dielectric strength, the duration and energy being regulated so that colour transport to the recording carrier is ensured below the recording electrode. The structure and constants of the transfer agent and the wiring of the recording electrode are selected so that the amt. of converting energy for the particle mobility needed in the transfer agent for local particle transport to the recording carrier is kept as small as possible, whilst at the same time the average static rupture voltage is small in relation to the operating voltage available at the recording electrode. The amt. of converting energy at a single 0.1 mm dia. electrode is 0.9 mVs.
