Patent DE-2715584-A1 (DE)
Title: Impeller of wind driven turbine - has blade linkage to vary pitch in response to forces due to changing wind speeds
Inventor: WORTMANN FRANZ XAVER PROF DR I
IPC: F03D13/20
Filed: 1977-04-07
Abstract: The impeller of a wind driven turbine has a shaft (1) to which a bracket (2) is keyed. The bracket provides a fixing for the blade linkage. An arm (3) is hinged to the bracket (2) and carries lugs to which the root (4) of the impeller blade is pinned. A link (6) pinned to the root is hinged to a lever (7) which is pivoted in a socket (8) on the shaft bracket (2). The linkage is such that oscillations in the tangential forces on the blade produce a rotation about its own axis. Variations in wind velocity are thus used directly to adjust the pitch of the blade to keep the power output constant without expensive and heavy machinery.

Title: Foot operated mixer tap for wash basin - has rocking pedal operating spool performing cut=off and proportioning functions
Inventor: CAMPEDELLI OTELLO
IPC: F16K11/065
Filed: 1978-01-20
Abstract: The wash basin has foot operation for water feed and mixing. A pedal is connected to a spool valve (8) connected to the cold and hot water pipes and to the water tap.

Patent DE-2814812-A1 (DE)
Inventor: KELLER MORITZ
IPC: H02J9/06
Filed: 1978-04-06
Abstract: An input voltage (Ue) supplies via a diode (7) and one series resistor (17, 9) each both the load (3) and a Ni-Cd cell (10) for maintaining operation in the event of power failure. A capacitor (36) which is charged in the pulse pauses supplies the pulse energy. The Ni-Cd cell (10) stabilises the supply voltage for the circuit (1). One switching device (24, 20) each, which is dependent on the voltage potential at one terminal (11) of the Ni-Cd cell (10), is present in in each case one supply lead (18, 19) to the load (3) or to a supply terminal (13) on the circuit (1). These serve the purpose of maintaining operation of the clock timer in the event of failure of the Ni-Cd cell (10), and are permanently open when the Ni-Cd cell (10) is short circuited, while they are otherwise conductive either permanently or only for the duration of the pulses. A stabilising diode (15) and a puffer capacitor (16) are connected in parallel to the supply terminals (13, 14). Transistors (20, 24) or a diode serve as the switching device. The transistors in the supply lead to the load (3) can be controlled by the pulse of the circuit (1). <IMAGE>

IPC: F42C15/188
Filed: 1978-06-12
Abstract: The hand grenade fuse with a detonator safety system has a swivelling firing pin and delay system. The detonator is moved on arming, by spring force from its safety position into the armed position. The safety element is a mechanical locking arrangement (10) connected with the firing pin (8). This locking system holds the detonator in the safe position. When the firing pin is swivelled, the fuse is armed. The holder (17) of the locking system causes swivelling of the firing pin in two stages. The firing pin is still safe at the end of the first stage but the lock of the detonator is already released.

Title: Activated sludge basin circulation device - using impeller and raking plough independent of oxygen intake
Inventor: DINNENDAHL MICHAEL ING GRAD
IPC: B01F7/16
Filed: 1979-01-05
Abstract: A travelling mechanism to maintain a circulation of a sewage-activated sludge mixt. in aeration basins of biological sewage treatment plant has >=1 impellers which are suspended from a revolving bridge. A raking plough moves along the basin floor and pushes the activated sludge into the circulation caused by the impeller. Circulation is thus clearly sepd. from the aeration function and the latter can be designed independent of the circulation requirements. Power is saved because the circulation is only local and does not involve the whole basin.

Title: Ultrasonic echo sounder scan for TV display - reads echoes from RAM store at variable rate to reproduce sector geometry
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N5/30
Filed: 1979-03-31
Abstract: A pulsed ultrasonic echo sounder scans over a sector. The train of echoes following each transmitted pulse is converted to digital form and stored in columns in a RAM store. The store is read out in lines to form a video signal for display on a conventional TV receiver. The read out speed of each line is changed progressively to reproduce the original sector scan shape. Further correction of the picture geometry is made by modulating the read out speed during a line. The correcting modulation is controlled by a code word derived from the scanner position and stored in the RAM at the start of each column.

Title: Fluid sterilising equipment - has UV lamp cooled by air passed over fluid tube
Inventor: BEARDA PIETER
IPC: A61L2/10
Filed: 1979-06-05
Abstract: The equipment sterilises fluids by means of UV. The source of the UV is a low-pressure, high-current mercury-vapour lamp with a 'U'-shaped discharge tube. A current of air (12, 13) is passed through the lamp (4) for cooling, and is so directed that the air heated by the tube is passed over the electrode boss (6) and to the outside of the fluid pipe (2). The air cooled by this pipe is returned to the lamp at a lower than the operating temp. of the projection (8) on the curve of the U-shaped tube to which it is delivered first. The temp. of this portion is regulated by a heater (9).

Title: Fixed marking suppression in Doppler laser radar system - distinguishes target from background by variation of laser beam cone geometry
Inventor: BORN GUNTHARD DIPL PHYS DR
IPC: G01S17/50
Filed: 1979-07-31
Abstract: The system is intended for safe differentiation between signals received from a moving or stationary target and its background. The targets are discerned from the fixed marking background by a time variation of the laser beam cone geometry, the beam diameter at the target to be made greater than the dia. of the respective target. For this purpose, an optical zoom system is used at the laser output, in order to modulate the opening cross section periodically over the entire magnitude of the opening angle (alpha). The doppler laser radar (10) modulates the output laser beam in such manner that its stray cones (11,12) in the direction of the moving target (13), so as to vary the intensity of the impinged surface element according to the magnitude of the openingangle. Since the target cross section remains fixed, the target reflected signal also varies in the same manner and in the time rhythm of the modulation.
