Patent DE-3540877-A1 (DE)
Title: Method for testing radial shaft seal rings
Inventor: UPPER GERD DR ING
IPC: G01M13/00
Filed: 1985-11-18
Abstract: A method for testing radial shaft seal rings, in which testing of the seal tightness is carried out to determine the integrity of the sealing edge and testing of the radial force is carried out in the shape of a measurement of the pressure to be exerted on the seal in order to lift the sealing edge, in such a way that for the purpose of testing the seal tightness the shaft seal ring is subjected on one side to air pressure and the leakage is measured, and for the purpose of testing the radial force the air pressure acting on one side on the shaft seal ring is increased to a value at which the sealing edge is raised from the shaft surface over the entire circumference, is distinguished according to the invention in that testing of the radial force is performed before testing of the seal tightness. This permits the shaft seal ring to be tested with greater reliability and with less outlay on time.

Title: Safety device for a relay
Inventor: SEEGER GUNTER A DIPL ING
IPC: H01H50/54
Filed: 1985-11-27
Abstract: The safety device for a relay monitors the fracture of contact springs, restoring springs and armature springs in that a loop current is passed through each spring, which loop current flows through at least a part of the length of the spring. If a fracture occurs in the region of the length of the spring through which the loop current flows, then the loop current is interrupted and a corresponding warning alarm is produced.

Patent DE-3546000-A1 (DE)
Title: Process and apparatus for the production of shaped articles (mouldings)
Inventor: SPALTHOFF ULRICH DIPL ING
IPC: B22C9/12
Filed: 1985-12-24
Abstract: The apparatus has a moulding box (40) containing a sand/binder mixture which can be hardened by means of a gaseous hardener. The moulding box (40) is connected via a gas line (38) to a vaporiser (36) in which the liquid hardener is vaporised. The vaporised gaseous hardener is mixed with a carrier gas/air stream and is passed through the gas line (38) to the moulding box (40). The amount of gaseous hardener required for hardening the sand/binder mixture results from metering the amount of liquid hardener, fed to the vaporiser (26), to correspond to the said amount of gaseous hardener. For this purpose, a nozzle valve (28) is located in the liquid line (24) leading from a pressure vessel (10) for liquid hardener to the vaporiser (26). The nozzle valve (26) has a valve (30) triggered by the pulses of a pulse generator (32), as well as a nozzle (34). <IMAGE>

Patent DE-3617652-A1 (DE)
Inventor: STEINECKE MANFRED DIPL ING
IPC: B29C48/06
Filed: 1986-05-26
Abstract: Extrusion head for sheathing a strand-form product, in particular a cable, comprises a central hollow mandrel having a central bore through which the product to be sheathed passes. An intermediate mandrel surrounds the central mandrel with an annular material flow channel between forward portions of the mandrels for applying a first layer of sheathing. The intermediate mandrel has at its forward end a parti-spherical enlargement by means of which it is mounted in a socket at the forward end of a tubular guide piece with a ball and socket type joint permitting angular movement of the intermediate and central mandrels relative to the guide piece which is received in a casing mounted on a support. A second annular material flow channel is provided between the casing and the intermediate mandrel for applying a second layer of sheathing. Material is supplied to the respective annular flow channels by extruders provided at opposite sides of the extrusion head through supply tubes connected with ball-type joints to preclude lodging of sheathing material.

Title: Automatic adjustment method for components of optical waveguides
Inventor: BERGER ANTON
IPC: G02B6/42
Filed: 1986-09-16
Abstract: The invention relates to a method for adjusting an optical waveguide fibre with respect to an electrooptical transducer element. According to the invention, radiation intensities with respect to a triple sensor in each case are in each case measured in one coordinate direction and values for the first and the second derivation of the radiation-intensity curve are calculated therefrom. Furthermore, in an imprecise search area defined by positive values of the second derivation, in each case a subsequent triple sensor is approached to a predetermined constant distance, the direction being determined by the sign of the first derivation, and in a precise search area defined by negative values of the second derivation either in each case a subsequent triple sensor is approached with the Newtonian method of approximation using the first derivation or in each case a double sensor is approached with progressive halving of the distances with determination of the direction as in the imprecise search area.

Patent DE-3637518-A1 (DE)
Title: Process for separating off acidic constituents downstream of fossil fuel plants
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/50
Filed: 1986-11-04
Abstract: It is known that in combustion boilers which bear acidic constituents in the flue gas, these are bound by blowing in lime substances. However, the degree of binding is far below 30% and thus in no way corresponds to the values demanded. In order to eliminate this disadvantage and to separate off the acidic constituents, in particular SO2, eg. at 90@, from the crude gas stream, according to the invention it is proposed that the loaded dust-containing crude gas stream from a coal boiler is predominantly separated from the ash via a cyclone (1) and an additive, preferably hydrated lime, is fed downstream of the cyclone station to a contacting section (8) which opens out into a chemisorption filter (3), the used lime from the filter (3) being collected in a silo (5) and fed again to the cyclone station, and the cyclone station being designed in such a way that the vortex chamber of the cyclone (1) contacts the as yet unreacted fine dust, eg. hydrated lime, with the crude gas, and thus forced multiple contacting with circulated used lime for SO2 binding is imposed upon the contact section (2) and the chemisorption filter (3). <IMAGE>

Patent DE-3642727-A1 (DE)
Title: Underwater motor-driven pump
Inventor: DUE JENSEN NIELS
IPC: H02K11/33
Filed: 1986-12-13
Abstract: The invention concerns an underwater motor-driven pump, consisting of an electric motor driving a pump coupled to it. The rotary speed and/or the torque of the pump can be varied by means of a solid-state frequency converter. By the use of large-scale integrated circuits and appropriate provisions for dissipating the heat losses of the frequency converter, the latter can be greatly miniaturised and located in a watertight, pressure-resistant enclosure. This enclosure forms a structural unit mechanically with the pump-motor set in such a way that the water pumped or to be pumped forms a heat sink for the heat losses to be dissipated.

Title: Solenoid for a solenoid valve
Inventor: HAFNER ERICH
IPC: H01F7/16
Filed: 1988-05-05
Abstract: The invention relates to a solenoid for a solenoid valve for gaseous or liquid media, having a coil core (11) fixed to the frame and a movable armature (13) which is acted upon by a return spring (14), the opposing pole faces (24) of which can be brought into contact, counter to the return force of the return spring (14), when the solenoid coil (10) is excited. Provided in the coil core (11) is a return passage (12) that emerges at the pole face (24) of the coil core (11). When the solenoid coil (10) is not excited, this return passage is connected to the clearance space between the pole faces in a manner which allows flow, and, when the solenoid coil (10) is excited, can be closed by a valve arrangement (23, 26). This valve arrangement consists of a valve seat (26) and a valve element (23), one of these parts being of flexible design and the spacing between them being smaller in this state than the spacing between the pole faces. According to the invention, the valve seat (26) and the valve element (23) are designed as rigid components. The valve element (23) is supported against a valve spring (19) and its freedom of motion is limited in the direction of pressure of the valve spring (19) by a stop (20) which determines the distance between its valve-sealing surface and the valve seat (26) in the unexcited state of the solenoid coil (10). <IMAGE>
