Title: Level indicator for windscreen washer reservoir - with electric switch to operate warning light when washer switched on
Inventor: PASCHKE HANNS-DIETER DIPL ING
IPC: B60S1/50
Filed: 1974-10-03
Abstract: The washer fluid reservoir of the windscreen/headlamp washers is fitted with a float which operates a microswitch when the level drops below a set amount. The switch is connected into a control circuit containing a signal lamp and a second switch operated by the washer pump control. If the level reaches the minimum then operation of the washer pump causes the indicator lamp to come on showing the driver that he has only a set amount of fluid left. The light only operates for as long as the washer is switched on and hence does not drain the battery when the vehicle is left unattended. A similar circuit can be used with a contact opening switch in which the indicator light is used to show that there is sufficient level in the reservoir.

Title: Hydraulic tensioner for large tie rods - uses metal sealing rings to apply very high hydraulic pressure
Inventor: SCHENK HORST
IPC: F16J15/3236
Filed: 1974-11-26
Abstract: The tie-rod (14) exerts a compressive load on the frame (12) of the press in order to prevent gaps occurring between the press cross-members and uprights. When heavy loads are exerted by the press a ring (19) with an annular groove (25) is placed under the nut (15) which is forced upwards by hydraulic pressure acting on the annular piston (20). The annular piston has a U-shaped groove with thin side walls on its under surface. A ring with a tapered cross section is forced by the hydraulic pressure between the side walls of the piston (20). The side walls are thus pressed against the walls of the annular groove (25) and provide an effective seal.

Patent DE-2528990-A1 (DE)
Title: Sepn. of oil-in-water emulsions - using ultrafiltration with membrane not permeable by oil with physical or chemical pretreatment
Inventor: PREEN WOLFGANG VON DR ING
IPC: B01D17/04
Filed: 1975-06-28
Abstract: Oil in water emulsions are sepd. using ultrafiltration with a membrane which is permeable to water but not to oil. This involves known physical or chemical processes or a combination of both for reducing the oil content prior to entering the ultrafilter. In order to operate the process continuously, a proportion of the oil enriched emulsion recycled from the ultrafilter is returned to the preseparation phase to remove the oil. Together with treated fresh feed, the recycled emulsion from which the bulk of the oil has been removed is fed back to the ultrafiltration feed tank. The preseparation process is held at such a pressure that the temp. can be well above the normal boiling pt. of the mixture. For use in preparing pure water from a water oil emulsion. The problem is that ultrafiltration is slow if an excessive amount of oil is present. Generally speaking separation becomes impossible once the oil content reaches 50%. The system described allows the bulk of the oil to be removed by other means e.g. centrifuging, only leaving the final frame to be removed by the ultrafiltration. This prolongs filter life and allows a virtually-continuous process to be developed.

Title: Self-steering mechanism guiding maize harvester along row - has pre-sensor to detect when plant is missing from row
Inventor: GRAEBER EWALD DR ING
IPC: G05D1/02
Filed: 1975-08-19
Abstract: Steering is controlled by the main sensor (3) which turns about a vertical axis (16) as permitted by its contact with the plants. If the machine steers towards the row the sensor shifts and makes one contact (15), and if away from the row the other contact (14). The corrective turn of the steering wheel this engenders is accompanied by a lengthening or shortening of the sensor's rod (18), which has the effect of releasing the contact that caused the correction. A pre-sensor (2) prevents the main sensor giving false indications when the plan is missing from the row. Then the spring-loaded (9) pre-sensor swings across and, at a certain point, operates switches (11, 12) which over-ride the main sensor and cause the machine to steer straight ahead until the row is found again.
