Title: Motor vehicle fuel consumption gauge - measures volumetric flow for successive equal distances and indicates it for distance covered last
Inventor: KIRCHER ULRICH DIPL ING
IPC: G01F9/00
Filed: 1977-09-13
Abstract: The fuel gauge uses a sum of pulses to represent the quantity of fuel consumed. The pulse sum proportional to the quantity of fuel consumed is started for every distance whose beginning and end is announced by a switching pulse from a distance meter. The mathematical product of the measured distance in metres and the pulse sount per cubic centimetre flow gives 1000, so that the pulse mum per measured distance represents consumption in litres per 100Km to one decimal place and shows the reading digitally.
Patent DE-2747988-A1 (DE)
Title: Motor vehicle transmission differential - has friction contact gears ensuring some torque transmission to non-slipping wheel
Inventor: GUEVARA REYNALDO S
IPC: F16H48/20
Filed: 1977-10-26
Abstract: The motor vehicle differential power transmission provides locking for traction if one wheel is on firm ground and other one is slipping. Several compensation gear wheels rotate in engagement between the axle shaft bevel gears. All these gears are spiral tothed with the teeth in sliding contact, so that high friction losses are generated. This ensures that free rotation of the driving wheels on the axle shafts is limited if the driving wheels are on slippery ground so that traction is improved. This contrasts conventional differential drive which has low friction between the gears.

Patent DE-2822979-A1 (DE)
Title: Wet settling jig yield control system for coal - scans height of datum layer denser than layer to be separated
Inventor: HEINTGES SIEGFRIED DIPL ING
IPC: B03B11/00
Filed: 1978-05-26
Abstract: The wet settling plant employs a throughput control system which, while using conventional float systems allows efficient separation of layers having only slightly different densities. The coal datum layer height with a density of material higher than the density of the material to be separated is scanned. The method makes use of the phenomenon that in the mixture of coal and mine waste, a layer forms which shows large differences of density. A float-operated discharge system reacts therefore after short travels and indicates the exact position of the layer in question. As the composition of the coal to be separated remains steady over a period of time, the scanning of the above layer allows the rate of discharge for layers above and underneath to be controlled.

Title: Drive selector for four wheel drive vehicle - has interlocks to prevent incorrect selection of locked differential operation
Inventor: MATTHAEUS MANFRED DIPL ING
IPC: B60W30/18
Filed: 1980-03-20
Abstract: The drive selector is for use on vehicles which have to traverse rough country as well as roads. To prevent selection of locked differential drive, operative on all axles, at a dangerously high speed electrical interlocks are provided which block execution of the selection instruction unless the road speed is sufficiently low and four wheel drive has already been selected. Low road speed is recognised through the gear ratio selected, and electrical switches in the interlock circuit only those in low forward or reverse gear. A further safety feature incorporated is an idle/drive selector which puts the main gearbox out of mesh in the idle position. This feature is typically interconnected with an auxiliary power take off or auxiliary equipment drives. It may also be interlocked with an auxiliary engine start switch outside the driving cab. Operation of all these circuits is locked out when the drive is selected.
