Title: Rotary tool and holder for fastening it in the tool holder
Inventor: SATUROV GENNADIJ FILIPPOVIC
IPC: B23B27/12
Filed: 1983-08-12
Abstract: A rotary tool contains a disc-shaped cutting element (6) which is fastened in an overhung position on the spindle (2) of the tool, which spindle (2) is arranged in bearings (3, 4, 5) which absorb the radial loads and the axial load and are accommodated in a bore (14) of the housing (1), the outer surface (12) of which represents a rotary-body surface. According to the invention, the bore (14) of the housing (1) is made eccentrically with regard to its outer surface (12), the geometric axes (15, 13) of the bore (14) and the outer surface (12) lying in the same plane (20). In the tool housing (1), radial tapped holes (17, 18, 19) for fastening the tool housing (1) in a holder are provided on the side of the outer surface (12) at the locations where the radial bearings (3, 4) are arranged. In addition, a holder for fastening the rotary tool is proposed in which the housing (43) has a bore for accommodating the tool housing (45) and holes for fastening elements (49, 50) and is constructed in such a way that it partly encloses the tool housing (45). According to the invention, the holder housing has end sections (54, 55), which bear against the surface of the tool housing (45), and a central section (56) in between which is at a distance from this surface, the holder housing (43) forming an enclosing angle for the tool housing (45) of 90 DEG  to 180 DEG .

Abstract: In a centrifugal pump for liquids and comprising seals (8) on the pump impeller (6) and a cooling stream which is guided along these seals (8) and which passes via a filter (20), said filter (20) is provided with a flushable cylindrical screen (21). The flushing flow passes from a guiding device (10), which is disposed downstream in terms of the conveying direction, into the region of the pump impeller discharge, as a result of which a pressure drop of at most half the discharge head can occur. The invention merits particular consideration for coolant pumps in nuclear power stations. <IMAGE>
Patent DE-3331690-A1 (DE)
Inventor: MATTHES HANS GEORG DIPL ING
IPC: H02M5/45
Filed: 1983-09-02
Abstract: The invention relates to a parallel resonant-circuit converter having at least one intermediate-circuit inductance. In order to guarantee that the inverter will start even with different loads, the voltage produced when discharging a separately charged capacitor across the load is monitored. At some time after the maximum voltage across the load is reached, another separately charged capacitor is discharged via a thyristor of the inverter located in the biasing circuit of the intermediate-circuit inductance. Because of the blocked thyristor and of the capacitor charged to the voltage maximum, the biasing current is forced to flow via diagonal branches and including the load. In this manner, reliable starting of the inverter is possible even with loads having a different natural frequency.

Title: Valve
Inventor: TRACH GUENTER
IPC: F16K1/14
Filed: 1984-08-30
Abstract: The valve proposed has a closing member (7) which is arranged in a holding cage (9) and is movable essentially along one axis relative to an associated valve seat (6) in order to control the flow of a medium through an opening (2) having the valve seat (6). The closing member (7) is arranged with limited mobility in the holding cage (9), the sealing region of the closing member (7) which adopts the inner defined position having an axial clearance (x) from the end of the holding cage (9) which can advantageously be preset when the holding cage (9) and the closing member (7) are assembled. The greater the clearance (x), the smaller is the radial mobility of the closing member (7) and hence the permissible centre offset of valve components given a certain unchanged geometry of the holding cage (9). <IMAGE>

Title: Circuit arrangement for displaying subscriber line seizures by ancillary devices on the associated digital telephone station
Inventor: SCHOENROCK RAINER
IPC: H04M3/30
Filed: 1984-10-12
Abstract: The invention relates to a circuit arrangement for displaying subscriber line seizures by ancillary devices in digital telephone systems. The intended object is to identify on the associated telephone station whether the subscriber line has been seized by the ancillary device. This display is intended to be possible independently of any special contact which may be provided in the ancillary device. To achieve this, a loop monitor, which in each case inserts a loop indicator into one wire of the subscriber line to both the telephone system and the associated telephone station, is inserted upstream of the ancillary device. If only the telephone system indicator identifies loop current, a signal is transmitted by the ancillary device as an indication of seizure through the actuation of a contact of the telephone system which transmits a corresponding digital signal to the telephone station. The invention is used in all digital telephone systems with ancillary devices on the subscriber lines. <IMAGE>

Patent DE-3508663-A1 (DE)
Title: Motor vehicle with all-wheel drive
Inventor: KREISKORTE HEINZ DR ING
IPC: B60K17/35
Filed: 1985-03-12
Abstract: In all-wheel drive motor vehicles without centre differential straining occurs, inter alia when cornering. In this process the front wheels are driven by the rear wheels. Between tyres and road surface the circumferential forces caused by the straining must also be transmitted in addition to the drive, braking and cornering forces. As a result the adhesion limit is thereby reached sooner. By fitting override clutches, which only permit the transmission of power to the wheels but not in the opposite direction, the straining and the additional circumferential forces can be prevented. By selecting somewhat different transmission ratios to the front and rear wheels it is possible for the vehicle, in normal operation, to be driven by only one axle and for drive torques to also be transmitted to the second axle if a certain degree of slip is exceeded.

Title: Elastic packed bed filters for vehicles
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H3/06
Filed: 1985-04-18
Abstract: It is known to use air cleaning filters for vehicle cabins in a packed bed filter configuration for removing gaseous contaminants. For reasons of space and arrangement, it is often necessary to build up the packing masses in the filter in such a way that the air flows through the filter masses at an angle of for example up to 90 DEG , that is perpendicularly to the direction of flow. In order, with this arrangement, to avoid the formation of undesired open spaces in the filter package, according to the invention it is proposed that the packing masses (2) are furnished with elastically deformable elements (4, 5, 6) which are embedded at the edge surfaces and/or in the packing masses (2) (Figure 2). <IMAGE>
