Title: Reducing residual moisture in solid-liq. sepn. - from flue gas desulphurisation, by adding weakly acid soln. to centrifuged solids
Inventor: HOELTER HEINZ
IPC: B01D53/26
Filed: 1977-11-03
Abstract: The final moisture content during a solid/liquid sepn. from wet flue gas desulphurisation plant is reduced in several stages.

Title: Wind driven power generator - has rotor within casing profiled to increase air velocity to utilise low wind speeds
Inventor: GREULICH KLAUS DIPL ING
IPC: F03D1/04
Filed: 1979-07-25
Abstract: The generator has a casing which can be rotated about a vertical axis to bring it into the wind. Within the casing there is a rotor (2) which carries aerodynamically profiled axial flow blades (1). The inner surface of the casing is profiled so that the cross section of flow reduces from the inlet (5) to the leading edge (4) of the blades (4). The air velocity is thus increased and the generator operates satisfactorily at very low inlet wind velocities. The pitch of the blades can be varied. The rotor and casing are profiled (7,8) so that this variation does not produce a gap round the blades.

Patent DE-2942583-A1 (DE)
IPC: B65G47/82
Filed: 1979-10-22
Abstract: Below the table surface (11) of, for example, a bank counter is a housing (12) in which a trolley (16) can be moved into positions C, D and E. The trolley (16) serves to receive a pneumatic post canister (15) which is guided to or away from it by the canister channel (14). In order to eject the pneumatic post canister (15) in position D, a helical spring (4) is used, which is linear in the unstressed state and is wound in a housing (1) on a motor-driven rotor with a shaft (17). The free end of the helical spring projects into the housing (12) and, when the rotor is turned, ejects the pneumatic post canister through the aperture in the table surface. The use of a helical spring (4) as an ejector means is simpler than pneumatic working cylinders. <IMAGE>

Title: Windscreen wiper system for rectangular window - has two overlapping wiper pivoted at diagonally-opposite corners
Inventor: SENNEBOGEN ERICH
IPC: B66C13/52

The wipers are synchronised so as to avoid one another. Each wiper is driven by its own electromotor. The two electromotors are controlled by a shared control unit. The advantage lies in the simple manner in which the greater part of the window is cleaned and esp. the important upper and lower edges of the window.
Patent DE-3024721-A1 (DE)
Title: Multiple output DC power supply - has one regulated voltage output and other outputs voltage limited by passive components
Inventor: STOLZ GERHARD
IPC: H02M3/335
Filed: 1980-06-30
Abstract: The application is to d.c. power supplies with at least two output voltages regulated by controlling the input to the d.c. converter. One output voltage is closely regulated, the other output is thus partly regulated, and is protected against overvoltage, e.g. due to loss of load, by a static element. The regulator (4) measures the controlled output voltage (Ua1) and adjusts the transistor chopper (2) on the d.c. input to the converter transformer (3) to an appropriate mark to space ratio. As the second output voltage (Ua2) is connected to a winding on the same transformer it is loosely regulated in accordance with the load (9) on the controlled section. To guard against overvoltages the second section (Ua2) is fitted with a Zener diode (10) and oppositely poled diode (11). If the Zener is conducting due to h.v. the spill current tends to flow in the load (9) of the controlled circuit. If this load is insufficient the voltage rises and the regulator (4) acts to correct the condition.
