Abstract: To maintain a loop closure of a telephone connection in a telephone system, an electronic choke (Dr) is connected between a first wire (a) and a second wire (b) of a pair of speech wires. The choke (Dr) exhibits, configured symmetrically, a DC sink containing a first transistor (T1, T1') and a DC source containing a second complementary transistor (T2, T2'). The first wire (a) is connected via a series circuit of the collector-emitter path (K1, E1) of the first transistor, a first comparatively low-impedance current setting resistor (Sr1) and a first constant-voltage unit (T3, R5, R6) to a first terminal (-) of an internal supply voltage (UB1). The second wire (B) is correspondingly connected to a second terminal (+) of the internal supply voltage (UB1). Furthermore, the base (B1) and the collector (K1) of the first transistor are connected via a first comparatively high-impedance voltage divider, a centre tap (1) of the first voltage divider (R10, R11) being connected via a first comparatively very high-impedance resistor (R1) to the first terminal (-) (symmetrically thereto, the second transistor being connected to the second terminal (+)). The first centre tap (1) is connected via a first capacitor (C1) (gyrator principle) and, in parallel therewith, via a series circuit of a third resistor (R3) and a forward-polarised diode (D1) to the ...

Patent DE-3642901-A1 (DE)
Title: Special screw thread for dental implant
Inventor: MOSER WALTER DIPL ING
IPC: A61C8/00
Filed: 1986-12-16
Abstract: The invention describes a special screw thread for endosteal dental implants which permits more favourable guiding of the chewing forces which arise into the jaw bone than conventional screw threads. This is achieved by a screw thread flank geometry which varies over the length of the implant. The danger of loosening of the implant which starts in the cervical region by formation of bone pockets can be reduced thereby. The effective screw thread flank area which increases greatly in the apical direction also avoids excessive strain in the spongy region.

Patent DE-3712685-A1 (DE)
Title: Separator
Inventor: SCHMIDT PAUL DR ING
IPC: B04C7/00
Filed: 1987-04-14
Abstract: Separator for solid and liquid particles from gases, constructed as a series connection of a radial and an axial cyclone. A maximum separator performance is achieved by using a guide apparatus in the separation surface of the radial cyclone, by utilising the swirl in a connected agglomeration pipe and by sucking off and returning a portion of the gas from the separation chamber of the axial cyclone into that of the radial cyclone. The opening of the connection line in the cyclone axis makes a second blower unnecessary. A collar with a guide apparatus prevents short-circuit flows between the agglomeration pipe exterior and the guide apparatus in the separating zone.

Title: Process and apparatus for dry toxic gas separation, such as SO3, SO2, HCl, HF and NOx, by means of an alkaline porous support material
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/68
Filed: 1987-10-01
Abstract: In the process described for dry gas purification, a porous support material impregnated with alkaline materials is added over the course of a reaction section to the gas stream and separated off again in a downstream filter device. In this case the sodium hydroxide solution and also the alkaline support material reacts with the acidic gas components. To separate off nitrogen oxides, an oxidant is additionally added to the support material. The added chemicals are mixed with the support material via an intensive mixer and are fed again to the flue gas stream via a mixing nozzle. A small part-stream of solids is taken from the process to which hydraulic binders and water are added in a mixer unit in order to produce, from the support laden with readily soluble salts, a leaching-resistant landfill product or a material for underground lagging work.

Patent DE-3817797-A1 (DE)
Title: Electrical rocker switch
Inventor: HAACK PETER
IPC: B60R16/00
Filed: 1988-05-26
Abstract: An electrical rocker switch is proposed which is provided with an illumination source and a light influencing element for illuminating translucent regions which are provided in the operating toggle which influences a switching element and can pivot about an axis. Such an electrical toggle switch is subject to the technical problem of using the illumination source to illuminate particularly uniformly the translucent regions which display a functional symbol on the operating surface of the operating toggle. This is achieved in that at least one operating attachment, which influences the switching element, and the shaft are provided integrally on the light influencing element, the operating toggle being assigned to the light influencing element in such a manner that any pivoting movement of the operating toggle is also transmitted to the light influencing element.
Patent DE-3823261-A1 (DE)
Title: Sealing ring which can be subjected to pressure from one side and serves to seal off two parts displaceable relative to one another
Inventor: BRAEUNIG LUDWIG SEBASTIAN
IPC: F16J15/3236
Filed: 1988-07-08
Abstract: In the case of a sealing ring (1; 39) which can be subjected to pressure on one side and serves to seal off two parts (3, 5) which can be moved relative to one another, preferably axially, the foot portion (17) of the sealing ring within an annular groove (15) in one of the parts to be sealed off consists of a guide lip (19) and of a sealing lip (21). The guide lip (19) faces the pneumatically pressurised side of the sealing ring (1; 39) and has knobs (27), grooves and similar geometrical elements opposite the side wall (23) of the annular groove, these elements ensuring a good pressure connection between the gap between the parts (3, 5) to be sealed off and the space (33) between the lips. In the case of a pressure build-up in the region of the pressurisable side of the gap between the parts to be sealed off, there is an immediate, essentially simultaneous pressure build-up in the space (33), giving rise to both an increased radial contact pressure of the sealing edge (11) or sealing edges (41, 43) of the sealing ring (1; 39) and to desirable lateral sealing contact of the sealing lip (21) against the facing side wall (35) of the annular groove (15). The pressure reduction is ensured by the knob and groove configuration of the guide lip with immediate release of air from the space (33). <IMAGE>

Patent DE-3843902-A1 (DE)
Title: Method for operating a high-voltage power circuit breaker (power switch), and a locking device for carrying out the method
Inventor: KARRENBAUER HERBERT DR DR ING
IPC: H01H3/30
Filed: 1988-12-24
Abstract: Spring drives for high-voltage power circuit breakers are known, in the case of which the latch is operated directly by a magnetic release. This has the disadvantage of long disconnection times (switching-off times). Hydraulic and pneumatic drives, in contrast, have the disadvantage that a high level of complexity (high cost) is required for energy generation and monitoring. Short disconnection times with a low level of complexity for energy generation and its monitoring are enabled according to the invention in that a spring-force energy store is locked by means of a locking device and is unlocked again for disconnection, said locking device being operated by a hydraulic drive. The invention furthermore provides various refinements of locking devices with hydraulic drives. <IMAGE>
