Patent DE-3140686-A1 (DE)
Title: Hydraulic dredger
Inventor: HIROSAWA KATSU
IPC: E02F3/42
Filed: 1981-10-13
Abstract: A hydraulic dredger comprises an articulated boom (11) with first and second arms (12, 13) which are connected to one another at the ends in articulated fashion and comprises a grab arm (14) which is coupled to a free end of the second arm (13). A loading bucket (38) is pivotably mounted on the free end of the grab arm (14). An articulated linkage (17) which comprises a lever (18) and hydraulic cylinders (19, 20) is mounted on a fully rotatable turret (10) and serves for pivoting the supporting arm (12) relative to the turret. One part (46) of the grab arm (14) can rotate about its longitudinal axis relative to the second arm (13). As a result, the loading bucket (38) can be adjusted into various positions, allowing the dredger to work either as a shovel dredger or as a front loader. <IMAGE>
Patent DE-3143349-A1 (DE)
Title: Method for determining slope in very noisy measurement signals
Inventor: MAYER EBERHARD DIPL ING DR
IPC: G01D1/00
Filed: 1981-10-31
Abstract: The detection of the change in a measurement signal for process control purposes is quite frequently impeded by superimposed interference, particularly noise peaks. Interposition of filters or increasing the sampling interval for gradient determination greatly delays the signal. In addition, noise peaks cause errors at the starting point and end point in the determination of a difference. The present invention has the aim of avoiding these disadvantages by only taking into consideration only a fraction of each change so that as a result, an exponential settling process is produced as response to a step change. A circuit arrangement suitable for this purpose primarily allows the evaluation with a time-independently exponentially decaying weighting when two process variables are logically combined so that the result becomes independent of the process speed. Attenuation factor and decay constant can be adjusted in this method.

Title: Centrifugal mill
Inventor: ROSENKE UDO
IPC: B02C13/08
Filed: 1982-02-02
Abstract: In a centrifugal mill (1) with a revolving centrifuge wheel (4), rotating in a housing (2) within a grinding ring (3), having impact tool leaves (6) arranged on the peripheral side, and also with a suction pipe (10) for the comminuted ground material connected at the end to the housing, a partition (11) is arranged between the centrifuge wheel and the housing end wall (9) on the suction side, and is limited in the radial direction, with the formation of an annular gap (14).

Title: Digital pulse-controlled inverter control set
Inventor: BUESCH GUNNAR DIPL ING
IPC: H02M1/084
Filed: 1982-05-06
Abstract: For a device for carrying out optimum voltage control of three-phase pulse-controlled inverters, to which a constant DC voltage is supplied, especially by an intermediate circuit, it is intended to specify the processing of pulse-controlled inverter voltage control variables which are present in the form of a digitally coded time-variable three-phase voltage system, using an optimum pulse pattern, in which device a large memory requirement is avoided. This is achieved in that intermediate variables (UE, UF) are produced from the voltage control variables (UA, UB, UC) with the aid of comparators (1, 2, 3) of a controller (4) and of a selector switch (5, 6), by means of which intermediate variables information is obtained from a switching cam memory (9) which contains only values of a 30 DEG  reference interval. This information is supplied to a state memory (13) to which information on the present 30 DEG interval is also supplied simultaneously from the controller (4). <IMAGE>

Title: Pressure cooker with safety device
Inventor: BEHNISCH ROLAND
IPC: A47J27/092
Filed: 1982-06-22
Abstract: The invention relates to a pressure cooker having a lid (12) which is held by a bayonet closure and whose radially projecting lid handle (16) is flush with the radially projecting pan handle (15) when the lid is secured and is prevented from being opened by means of a safety device until the interior of the pan has been vented.

Patent DE-3227394-A1 (DE)
Title: Safety locking device
Inventor: ESSER HANS
IPC: E05B65/08
Filed: 1982-07-22
Abstract: The safety locking device for vending machines is equipped with a pressure-cylinder lock. To achieve greater safety against the unauthorised opening of vending machines, a double-walled locking pocket and a locking tab penetrating into this between the two walls together with the pressure-cylinder lock are provided. The locking pocket is arranged on the fixed part of the vending-machine housing and the locking tab on the movable part of the latter. The locking tab penetrates into the orifice formed as a result of the double-walled nature of the locking pocket. The orifice is laterally closed, that is to say cannot be burst open by means of a lever effect. The locking tab contains the pressure-cylinder lock in a receiving casing, in such a way that the fastening is located on the rear side or inside and consequently is not accessible in the melted state. The locking bolt projects on the rear side from the locking tab and, during the closing of the pressure-cylinder lock, penetrates into a bore provided on the rear side of the locking pocket.

Title: Apparatus for obtaining drinking water
Inventor: KUECKENS ALEXANDER
IPC: E03B3/28
Filed: 1983-06-01
Abstract: In order to obtain drinking water in large quantities, the invention provides a floating carrier, such as a pontoon, ship, raft or the like, on which heat-exchanger surfaces are in direct contact with the outer atmosphere and are connected, by a heat-transfer-medium circuit to heat exchangers which are arranged on the floating carrier beneath the water surface in order to give off the heat, received from the outer atmosphere, to the water. The arrangement is designed such that, on the heat exchanger surfaces in contact with the atmosphere, the air humidity is condensed, collected and channelled into tanks of the floating carrier. In order to operate the arrangement there are operated, on the floating carrier, wind energy generators which supply the drive for the circuit-circulating device and a heat pump which serves further to reduce the heat transfer fluid guided in the circuit.
