Title: Method and device for automatically aligning a target or a measuring instrument
Inventor: GAECHTER BERNHARD F DR
IPC: G01C15/00
Filed: 1984-08-30
Abstract: For the automatic alignment of a target point with a measuring instrument, for example with a geodetic instrument, the target point is irradiated with an optical transmitter (30) from the measuring instrument (10). At the target point (20) several receiver surfaces (1-6) are arranged parallel to the axis to be aligned, and distributed at equal angles around this axis. The target point is rotated until the signal difference from two adjacent receivers (1, 2) becomes minimal. A reverse alignment from the target point to the measuring instrument is also possible. <IMAGE>
Patent DE-3433046-A1 (DE)
Inventor: BLECKMANN GERHARD
IPC: B41F27/12
Filed: 1984-09-08
Abstract: To close the gaps (6) which result between the end or edge sections (7) of the gravure printing plates (2) when the latter are clamped on form cylinders (1) of rotary gravure presses, the gap (6) is covered with a cover element (8) in which at least that surface region which lies on the end or edge sections (7) of the gravure printing plate (2) and covers the gap (6) is deformable under pressure and can therefore be matched up with the surface contour in the gap region, the cover element is pressed onto the surface of the gravure printing plate, the resulting gap cavity is filled with a curable filling compound and, when curing of the filling compound is complete, the cover element is removed. It is particularly advantageous to use cover elements which are in the form of hollow bodies and which are filled with a pressure-generating and pressure-transmitting medium, and the pressure exerted on the deformable surface of the cover element which lies on the gravure printing plate, and hence also the surface contour of the closed gap, can be controlled via the internal pressure in the cavity of the cover element.

Title: Method of investigating the contact behaviour of heavy-duty contacts
Inventor: BLEIBTREU ALEXANDER
IPC: G01R31/04
Filed: 1984-09-11
Abstract: A method of investigating the contact behaviour of heavy-duty contacts of a current path loaded with continuous alternating current. The alternating current flowing in the current path is at the same time superimposed with a direct current which is formed from half-waves of the same frequency and the effective value of which is a fraction of the effective value of the alternating current. Then the voltage drops at in each case two measuring points lying as close as possible to the actual contact point and at two further measuring points lying anywhere in the current path outside the contact point are measured by means of measuring electronics. The measuring electronics eliminate any interfering alternating quantities by means of corresponding filters and, from the measured voltage drops, uses only the likewise filter-smoothed effective value of the direct current for determining the contact resistance and the power loss created in the contact resistance.

Title: Drive circuit for a light-emitting diode
Inventor: RUEGENBERG GERVIN
IPC: H04B10/508
Filed: 1985-01-24
Abstract: In order to achieve light pulses whose edges are as steep as possible, by means of a light-emitting diode, a parallel circuit is inserted into the supply circuit of the diode, which parallel circuit consists of a first capacitor, a resistor and a second capacitor which is connected in series with the diode, the parallel circuit diode being in the opposite polarity to the light-emitting diode, and a bleed resistor being connected between the parallel circuit diode and the second capacitor. The second capacitor is charged for the duration of a current pulse which energises the light-emitting diode and, at the end of the pulse, supplies an additional depletion current which quickly blanks the light-emitting diode and can be measured irrespective of the switching-on current surge which is caused by the first capacitor at the start of the pulse. <IMAGE>

Title: Anti-freeze flap for car door locks
Inventor: THUERER HARRI
IPC: E05B17/00
Filed: 1985-03-18
Abstract: To prevent car door locks from icing up in wintertime, deicing sprays or plastic plugs etc. have preferably been used hitherto, but these, when needed, have often been left in the locked vehicle and therefore been out of reach. The novel anti-freeze flap eliminates these and other deficiencies, in that the slotted flap provided with adhesive is bonded to the door lock at the beginning of Winter and the other upper flap seals off the door lock simply by being pressed down. When the upper flap, which is connected by means of a hinge neck to the lower flap bonded to the lock, is lifted off, the door-lock slot is exposed, so that the lock can be opened by means of the key. The anti-freeze flap remains fastened to the door lock throughout the Winter and easily prevents car door locks from freezing up when they are stationary or in an icy relative wind. It is impossible for moisture, rain and washing-system water, etc. to penetrate into the cylinder of a car door lock and freeze up by the effect of cold.

Title: Joint fitting for seats with adjustable backrest, in particular for motor vehicle seats
Inventor: WALK HANSJOERG ING GRAD
IPC: B60N2/225
Filed: 1985-11-16
Abstract: The joint fitting for seats with an adjustable backrest comprises a fixed joint component which is assigned to the seat and a pivotable joint component which is assigned to the backrest. These joint components are connected to one another by means of a pivot axis, an adjusting and fixing device which determines the position of the two joint components with respect to one another and is constructed as a so-called gear system being provided. The drive of this fixing device is effected via the pivot axis, the self-locking of the gear system being increased by an elastic brake ring arranged in the axial direction between the pivot axis and a joint component. In order, on the one hand, to apply a brake torque to the pivot axis in the descending direction of the backrest and, on the other hand, to obtain a free-wheeling effect in the opposite direction, the brake ring is constructed as a compression spring which is connected at one end fixed in terms of rotation to a joint component and at the other end to the pivot axis via a toothing which has, on the one hand, a blocking and, on the other hand, a releasing effect.

Title: Apparatus for polishing the blade projection of knives
Inventor: HAUSCHILD WILHELM
IPC: B24B19/00
Filed: 1986-05-17
Abstract: The invention is directed at an apparatus for automatically polishing the blade projection of knives (60) with a blade foot projecting relatively unaided, said apparatus having a polishing disc (42) which acts, on both sides, with its circumferential face, on the blade projection region of the knife blade, in the meantime held in a clamping device (58), and, during this process, performs an oscillating feed movement. In this arrangement, a plurality of pairs of polishing discs (42) which can be advanced towards one another are arranged in successive work stations passed through by the same clamping device (58), of which at least individual polishing discs are able to assume an axial position inclined with respect to a longitudinal mid-plane of the blade (62) normal to the plane of the blade. An improved polishing effect in this critical region is thus achieved, with which ghost lines can be made to disappear. <IMAGE>
Patent DE-3616797-A1 (DE)
Title: Steam turbine system
Inventor: JUNIOR ALFRED DIPL ING
IPC: F01K7/40
Filed: 1986-05-17
Abstract: Steam turbine system having a multistage steam turbine whose exhaust steam side is connected to a condenser whose condensate is fed by means of a pump via a series of heat exchangers to a steam boiler for the purpose of feeding the turbine. The heat exchangers are connected via bleeding (tapping, extraction) pipes to bleeding (tapping, extraction) points of the steam turbine. In each case, a bleeding point with a higher pressure is connected to a heat exchanger with a higher temperature, and an adjacent bleeding point with a lower pressure is connected to a heat exchanger with a lower temperature. Arranged at a bleeding point of higher pressure is the drive side, and at a bleeding point of lower pressure the suction side of a steam-jet compressor whose compression side is connected to an auxiliary heat exchanger which is connected downstream of the heat exchanger which is connected to the bleeding point to which the suction (intake) side of the steam-jet compressor is connected. The effect of the steam-jet compressors is to raise steam subflows of low enthalpy states to a respectively higher enthalpy state and to put them to use to prewarm condensate at this level. The corresponding bleeding subflows, which are no longer required, remain in the steam turbine and generate additional power. Consequently, there is an improvement in the thermal efficiency of the thermodynamic process and thus of the steam turbine system. <IMAGE>

Title: Method for carrying out reductive pyrometallurgical processes with pellets of oxide ores, concentrates or intermediates and also metallic intermediates by means of strongly reducing gases or oxygen-containing gases for the production and refining of a molten metal
Inventor: BOCK ULRICH
IPC: F27D99/00
Filed: 1986-08-30
Abstract: In a furnace chamber of cylindrical shape, a strongly reducing flame is blown via a pulsed burner centrally on to the surface of the charge or bath. This flame from the combustion of pure oxygen with natural gas, propane or light oil can have a reduction potential of PO2 = 10<-12> atmospheres. This flame impinging on to the surface of the charge or bath is deflected, sweeps across the surface and induces a stirring effect in the melt. The mass flow, obtained by convection, between the surface of the charge and bath and the reduction flame leads to a reduction of the metal oxides in the melt. The gases rising on the side walls of the cylindrical furnace chamber and still containing CO and H2 are finally burned by air which tangentially enters the upper part of the cylindrical furnace chamber at high velocity. A major part of the heat thus released serves for heating the reduction flame which is relatively cold in the case of greatly sub-stoichiometric operation. This allows intensive reduction work coupled with a considerable lowering of the energy consumption.
