Title: Multi-stage pump turbine for gas-charged liquids
Inventor: GAFFAL KARL
IPC: F03B3/10
Filed: 1983-03-12
Abstract: The gas emission processes occurring in the turbine operation of multiple-stage pump turbines for gas-charged liquids can lead to accumulations of larger quantities of gas inside the flow ducts of the pump turbine and hence to a fall in power output. If a relief device serving for axial thrust compensation is present the gas emissions occurring in the area of the relief device can lead to influencing of the axial thrust and thereby to problems in the axial thrust compensation. 
<??>In the pump turbine according to the invention the quantities of gas occurring in the expansion process are removed by way of openings, which are each arranged in the area between a rotor wheel and a guide wheel in the vicinity of the shaft of the pump turbine and are connected to the pump intake connection by way of ducts in the shaft and/or the hubs of the rotor wheels. The gas precipitated in the area of any relief device is either also removed to the pump intake connection or is carried off into the expansion chamber of the relief device and from there drawn off by way of one or more bores of the pump turbine.

Patent DE-3319489-A1 (DE)
Title: Axial piston machine
Inventor: GRIESE KLAUS DIPL ING
IPC: F01B3/00
Filed: 1983-05-28
Abstract: The swivel plate (19) of an axial piston machine is supported in brackets (24, 25) which are fixed on the cover (11) of the housing (10). The control surface and the admission and discharge ducts for the machine are located in this cover. The brackets (24, 25) are not connected to the housing (10), which is likewise fixed directly on the cover (11). This prevents drive mechanism forces being transmitted by way of the housing to the solid cover, the line of forces instead passing directly from the swivel plate (19) by way of the brackets (24, 25) to the cover (11). In this way, good isolation of the structure-borne noise is achieved, thereby significantly reducing noise. <IMAGE>

Patent DE-3335237-A1 (DE)
Inventor: BINDER ALFRED
IPC: B23B45/02
Filed: 1983-09-29
Abstract: A method and apparatus for controlling an electric motor, in particular a motor for driving hand tools, saws, and the like, the rotational speed of which is automatically reduced in no-load idling operation and increased when working under load to pre-determined speed values corresponding to desired working speeds. A current sensor picks up the current absorbed by the electric motor and causes the speed of the electric motor to be abruptly changed when a load condition has been detected. A timing relay maintains the electric motor at the higher working speed for a pre-determined period of time after termination of the operation under load. The threshold value of the sensitivity of the current sensor is raised simultaneously with the change-over to the higher working speed.

Title: Device for testing overload safety devices on lifting appliances
Inventor: BLAIMER ALBERT
IPC: B66C15/00
Filed: 1983-11-15
Abstract: A device for testing overload safety devices on lifting appliances which has a shearing pin, cutting the power flow in the load member in the event of the permissible limit load being exceeded, and a braking device having a rope wound around a rope drum is described and is to be improved in such a way that the load relief of the lifting appliance occurring when the shearing pin is sheared off is immediately detected by the braking device, and the lifting mechanism is gradually relieved of load. The novel device essentially consists of two components which can only move slightly away from one another. A rope wound onto a rope drum mounted rotatably but as a rule in a locked manner on one component, which rope lies in the power path, can unwind when the shearing pin is sheared off and thus permits the movement between the two components. The shearing pin is mounted in the component carrying the rope drum and in an arm of a shearing lever rotatably mounted on this component. The other arm of the shearing lever ensures that the other component is held in a position in which the rope drum is locked. <IMAGE>

Patent DE-3414929-A1 (DE)
Title: Radio monitoring system
Inventor: SILLIFANT MARC ROGER
IPC: H04B17/00
Filed: 1984-04-19
Abstract: In monitoring the radio spectrum for the possible presence of signals of unknown origin, it is not only necessary to detect signals of this type with accuracy even in the event of substantial power and signal amplitude fluctuations and a poor signal-to-noise ratio. It is moreover also necessary to identify their modulation type and signal structure quickly and reliably by means of automatic modulation analysis if the intention is to be able to demodulate and analyse them. For a radio monitoring system of this type, a modulation analyser (MA) is proposed which, along with a control and evaluation circuit (ST), has a signal detector (SD) for the modulation characteristics and a high-resolution spectrum analyser (SA) which is similarly controlled by the latter. The spectrum analyser periodically samples the frequency of the signal fed to it in the width of a speech channel and supplies the sampling values which are in each case associated with a frequency interval to a histogram generator which simultaneously retrieves from the generated signal regularity pattern the fundamental signal criteria which are required in order to identify the signal composition. <IMAGE>
