Title: Motorway traffic disturbance measurement - is derived from speed and density values obtained at spaced measuring stations and compared with reference values
Inventor: BOETTGER ROLF DR ING
IPC: G08G1/01
Filed: 1979-03-26
Abstract: Disturbances or bottle necks to traffic flow on motorways are measured at measuring stations spaced a large distance apart. The measurements obtained are traffic density and speed to permit calculations to be made. A section of motorway with two lanes in each direction has two access points (AS1) each with an entry (EF) and exit (AF). Each lane in each direction has two detectors (D) arranged one behind the other with detectors in the entries (DE) and exits (DA). This arrangement allows the density of traffic to be determined on the motorway and at the entry (Z1E) and exit (Z1A) points. The value obtained is compared against the value at a second station in order to determine the presence of a bottle neck. If this exists a suitable warning can be issued to vehicle drivers.

Title: Frequency and pulse converter - changes weak slow rise time into sharp output pulses by using magnetostrictive centre in coil to drive electrostrictive outer parts
Inventor: ANGERMAIER HUGO
IPC: H01L41/00
Filed: 1979-03-30
Abstract: The converter changes electrical oscillations or pulses into electrical signals of different waveform using a magnetostrictive centre plate (1) with electrostrictive outer parts (2, 3). The outer parts each consist of electrostrictive ceramic plates with silver electrodes (4-7) on each face and are located above and below the centre plate. One or two coils are wound round the resulting sandwich. Insulating layers may be located on the top and bottom surfaces of the centre plate. The converter's performance is largely independent of the magnitude of the input signal's current. The output signal is electrically isolated from the input signal. The magnetostrictive part also acts as drive for the electrostrictive parts. A pulse applied to one coil results in a voltage across the electrodes of the outer parts having the shape of a decaying exponential function. Weak input pulses with rounded edges result in a sharp output signal.

Title: Electric conductivity monitor for highly purified water - has electronic switch connecting display and/or actuator to source only, when electrodes are dipped in water
Inventor: ALHAEUSER ERICH
IPC: G01N27/07
Filed: 1979-06-15
Abstract: The water of high purity, whose electric conductivity is monitored, is supplied from a generator, or reservoir. The monitoring is carried out by a display and/or actuating device which is controllable by the electric current between two spaced electrodes, located in the flow path of monitored water. The display and/or actuating device is connected to an electric power source by a switching device only when the two electrodes are dipped in the water. The switching device is preferably actuated mechanically by the tapped water and may be in the form of a water pressure actuated switch. This pressure may be generated by a dam or a throttle in the water flow path, while a differential pressure switch may be used. A mercury switch, or a float switch may be also used in the system. The monitoring system finds typical application in the pharmaceutical industry.

Each photothyristor or phototransistor and its l.e.d. are accommodated inside a housing (G1,G2) which excludes light. The arrangement prevents back coupling with e.g. driving transistors, and clean trigger pulses are obtained.

Title: Dry desorbate, esp. solvent recovery from activated charcoal - by passing circulating gaseous inert desorbent through adsorptive drier before condensation
Inventor: WINTER KARL DIPL PHYS
IPC: C01B31/08
