Title: Vehicle rear mirror arrangement - has set of auxiliary mirrors with final receiving mirror almost in direct line of vision
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: B60R1/10
Filed: 1974-01-08
Abstract: Outside rear mirrors, whether mounted on the door or on the wing have the disadvantage that the driver when intending to change lanes on a motorway has to turn his head towards the mirror hereby neglecting temporarily his observation of the road ahead. The first step in a possible improvement of this disadvantage is a second mirror inside the car within a straight line of vision of the driver reflecting the image transmitted from the outside mirror. This image however will have the wrong handing. By inserting a further mirror the handing is reversed giving a correct image.

Title: Crude oil electrodehydrator control - by automatic adjustment of oil/water flow ratio within electrode current limits
Inventor: PAWLOW NIKOLAI IWANOWITSCH
IPC: C10G33/08
Filed: 1975-05-21
Abstract: Crude petroleum can be treated in electrodehydrators for desalination and dehydration. An automatic control is effected by changing the crude oil-to-industrial water ratio which is measured by separate flow meters. The pulse control includes two amplitude selectors at the output of a differentiator, and two pulse counters on the amplitude selector outputs to feed a programmed time relay. The pulse counters also feed positive and negative correction pulse shapers to keep the control within limits which ensure that there is no flashover between the electrodes. The control system ensures stable operation at any fluctuations of the oil/water ratio. The optimum sequence is determined automatically for various grades of crude oil and the desalination/dehydration process is maintained at a better efficiency.
