Patent DE-2416112-A1 (DE)
Title: Flow control flap for jet thrust rotor blade - is mounted inside thrust duct for effective and compact design
Inventor: GOERGL GEORG
IPC: B64C27/18
Filed: 1974-04-03
Abstract: The rotor blades are propelled by thrust jets inside the rotor blades and expelling gases out of the tips of the blades. The cross section of the jets is widened on one side to hold the pivot bearings for the thrust control flap. This enables the flap to be mounted in the ducts without impeding flow, and without intruding into the rotor blade space. The operating linkage for the flap is mounted along the insdie of the wider edge of the blade for a smooth, unobtrusive mounting. The rotor is particularly for use on a helicopter.

Title: Spring clip for retaining shafts or bolts - is formed from strip and fits in circumferential groove spaced from shaft end
Inventor: BURK GERHARD
IPC: F16B21/16
Filed: 1974-04-06
Abstract: The shaft or bolt to be secured is provided with a circumferential groove a short distance from its end face. The retaining clip, which is made from one piece of strip metal, is provided with a keyhole slot.

Title: Level indicator for filling materials - has air pressure in pneumatic line changed by amount of lateral or base pressure
Inventor: LESK ADOLF
IPC: G01F23/22
Filed: 1974-04-10
Abstract: The pressure change is made recognisable as an electrical signal by means of a pressure gauge or a suitable converter. The pressures varying as a result of the filling height can be used for the continuous measurement of the filling height. The pressure of the filling material can close wholly or partly by means of a diaphragm the air outlet from the pneumatic line. In the case of suitable filling materials, the resistance presented by the filling material to the issuing air can be used to measure the filling level. A fixed or variable air resistance can be incorporated to adjust the consumption of air.

Title: Liquid cooled power transmission cable - high voltage system may be three phase or DC operation
Inventor: FISCHER WILFRIED DIPL PHYS DR
IPC: H01B7/42
Filed: 1974-04-13
Abstract: The cable comprises a tube carrying the coolant fluid, typically water or oil. A conductor may be placed in the bore of the tube and/or around the outside. The most economic arrangement of cable parameters and pumping station distance is given by relating a function of the cable hydraulic diameter, length, and transmitted power to a function of the operating voltage which has a coefficient dependent on a number of parameters including losses, coolant friction and specific heat, permitted temperature rise, and pressure drop. For water cooled cable in a three phase system this coefficient is chosen to lie between 1.7 x 10-7 and 8.4 x 10-7, and for oil cooling between 2.3 x 10-7 and 11.8 x 10-7.

Title: Communal aerial with multiple branching facilities - has equal attenuation at input of each branch by correct branch relationship
Inventor: BEYER KLAUS
IPC: H01P5/12
Filed: 1974-04-20
Abstract: The communal receiving aerial with multiple branching facilities is intended for distributing high frequency television signals to different receivers. The transmissionis directional and the branch junctions are in a row. Each branch has an input and an output and second branching facility. The attenuation between the input and output of each branch is low. The attenuation between the input and the second branch is relatively high compared to the transmit attenuation. The attenuation between the input of the communal aerial and the branch inputs is more or less the same in all. This is achieved by calculating the required relationship between the input at each branch and the combined effect of all the preceding branches.

Title: Vehicle brake antiseizing electropneumatic actuator - has additional volume chamber for increasing system pressure until released by further signal
Inventor: ECKART ALFRED
IPC: B60T8/50
Filed: 1974-05-25
Abstract: The pressurised medium actuated relay valve is used especially for electropneumatic actuation of motor vehicle brakes. The valve ensures that actuating pressure is not reduced when the system is to be held under constant pressure. The brake is released only to an extent specified by the signal for stopping pressure reduction. The inlet and outlet valves are controlled by a piston and the actuating pressure is controlled by solenoid actuated inlet and outlet valves. The control chamber is connected to an additional volume for increasing the pressure in the control chamber, after pressure holding signal, to a level which depends on the controlled pressure reduction in the additional volume.

Title: Photodetector circuit with differential amplifier - generate output proportional to incident light intensity despite high current drift of amplifier
Inventor: STAHL HARALD
IPC: H03F3/08
Filed: 1975-01-23
Abstract: The photodetector generates an electric output signal proportional to incident light intensity using a differential amplifier (3) with high current drift. The photosensitive element (4) is connected between the amplifier inverting and non-inverting inputs. The output of the amplifier is connected via a feedback resistor (1) to the inverting input.

Title: High protein prod for fodder - made from lucerne by compression-expansion disintegration and ultra-filtration of liq phase
Inventor: KOHLHEB ROBERT DIPL ING
IPC: A23J1/00
Filed: 1975-02-01
Abstract: High-protein prods. are manufactured from vegetable matter (lucerne) which has been cut up by feeding it by a worm conveyor to a disintegrator which operates on the compression-expansion principle. The pulp is separated in a filter centrifuge into a solid and a liq. phase. The liq. phase is separated by ultrafiltration; the concd. high-protein liq. is preheated and dried in a vacuum dryer. This process achieves a maximum recovery of the cellular fluid which contains most of the proteins. The albuminous extract is concentrated with little detriment to its contents by reducing the residence times. The process is a profitable and practical method of concentrating proteins for animal fodder. The power consumption is low.
