Patent DE-3539038-A1 (DE)
Title: Oxygen probe
Inventor: KOERTVELYESSY LASZLO DIPL PHYS
IPC: G01N27/406
Filed: 1985-11-04
Abstract: Hitherto it had not been known that temporary drifing of the Nernst voltage gives rise to errors in conventional oxygen probes. These errors can be avoided in a surprisingly simple manner; the zirconium oxide tube and the gas electrode must be heat-insulated with respect to the external protective tube.

Patent DE-3606374-A1 (DE)
Title: Mixing device
Inventor: BONNET DIETHARD
IPC: B01F5/00
Filed: 1986-02-27
Abstract: The mixing effect of known mixing devices for mixing liquid and/or pulverulent materials is that the mixing element imparts a turbulent flow to the materials. However, such a flow cannot be established in the case of extremely highly viscous materials. In order to blend such highly viscous materials, according to the invention a disc pair is provided, comprising a stationary disc and a rotating milling disc, which blends the materials via thorough milling. <IMAGE>

Patent DE-3628981-A1 (DE)
Title: Printed circuit board
Inventor: STOLLFUSS HANS-WERNER
IPC: H05K1/14
Filed: 1986-08-26
Abstract: The printed circuit board (30) carries components (41) and structural units (42) of an electrical circuit in such a manner that functional groups (20, 21) are formed which are associated in terms of circuitry. The components (41) and structural units (42) as well as the associated conductor tracks of each functional group are accommodated on a specific printed circuit board region (31, 32) of the printed circuit board (30). The printed circuit board regions are separated by intended-fracture lines (lines of perforations) (34). In consequence, printed circuit board regions which require repair can be separated from one another simply by breaking them off. The intended-fracture lines (34) preferably consist of a row of holes (36) which are incorporated in the printed circuit board (30). <IMAGE>

Title: Piston engines with methods for improving the reaction in engine combustion chambers and secondary reaction areas
Inventor: LEISTRITZ HANS KARL DR
IPC: F02B1/04
Filed: 1987-06-02
Abstract: This application is an additional application to P 3700182.5, which bears the title: Reciprocating-piston engine with methods for improving the reaction in engine combustion chambers and secondary reaction areas. The additional application is concerned with the need to reduce the increasing resistances to flow within the exhaust pipe which result from the increasing pressure and the increasing exhaust outlet temperature in the case of relatively high engine speeds and loading because the space geometry of the pipe remains the same. For this heat dissipation, the application describes measures which bring about cooling by the relative wind, an obvious measure in motor vehicles, by means of special internal design features of the exhaust pipe.
Patent DE-3720298-A1 (DE)
Title: Metal layer arrangement for thin-film hybrid circuits
Inventor: KROKOSZINSKI HANS-JOACHIM DIPL
IPC: H01L23/498
Filed: 1987-06-19
Abstract: The proposed metal layer arrangement is used to form electrodes and/or conductor tracks, and consists of at least one aluminium layer (3, 7, 13, 17) and a thin copper layer (4, 6, 14, 16). The aluminium layer is thicker by a factor of approximately 20 than the layer thickness of the copper layer. When the metal layer arrangement is covered by an insulating layer such as, e.g., a dielectric layer (5) of a thin-film capacitor or a crossover oxide layer (15) of a thin-film conductor track crossing, the copper layer (4, 6, 14, 16) is either to be applied between the aluminium layer (3, 7, 13, 17) and the insulating layer (5, 15) or is to be enclosed between two partial layers (3a, 3b, 7a, 7b, 13a, 13b, 17a, 17b) of the respective aluminium layer. The copper layer (4, 6, 14, 16) diffuses into the aluminium layer (3, 7, 13, 17) upon annealing of the entire circuit, without destroying the insulating layer (5, 15) in the process. This prevents the growth of hillocks and reduces the electromigration at the same time. <IMAGE>

The spray nozzle (7) on the end of the pipe can have a washer brush (6) screwed into place. USE/ADVANTAGE - Simple, effective vehicle wash unit is independent of a central water and electricity supply.
Patent DE-3726305-A1 (DE)
Title: Tool-clamping device
Inventor: STUCKI FREDY
IPC: B23B31/26
Filed: 1987-08-07
Abstract: When the tool (20) was expelled, a locking pin (58) was displaced by a piston rod (30) until it came to bear on the upper margin of a spherical bush (59) and then the latter was displaced together with the locking pin (58) by an amount of travel "b". A collet (28) of the gripping system was released by a control edge (59) for opening. The retraction of the novel tool takes place in the reverse sequence. After the piston rod (30) is retracted, a return spring (60) returns the collet (28) and the tie rod (48) with spherical bush (49) into the locking position and a locking spring (61) returns the locking pin (58) into the locking position. After a piston rod (31) is retracted, the clamping force of disc springs (53) again acts on the separating point between tool and spindle, whereby the tool change is complete. With the tool-clamping device, larger clamping forces and/or greater amounts of travel than are possible with known systems can be achieved. A more rigid connection between tool and work spindle results. More material per unit of time can thereby be removed from the workpiece to be machined. Shorter machining times can be realised. <IMAGE>

Inventor: DISTELDORF JOSEF DR
IPC: C08G18/79
Filed: 1987-11-21
Abstract: The object of the invention was to develop a highly selective process for the preparation of uretdiones of (cyclo)aliphatic diisocyanates which does not rely on the use of catalysts which are difficult to prepare and involve a cancer risk. 
<??>This is achieved by reacting (cyclo)aliphatic diisocyanates having 6 to 15 carbon atoms or mixtures thereof in the presence of 4-dialkylamino-substituted pyridines until a degree of dimerisation of 10 to 80 % is reached and subjecting the reaction mixture to a vacuum thin-film evaporation, in which the uretdione is formed as the distillation residue. 
<??>The process is suitable in particular for the preparation of the uretdione of isophorone diisocyanate, which in turn is used in polyurethane paints.

Inventor: BUCK WALTER DR
IPC: H04B7/08
Filed: 1987-12-21
Abstract: The amplitude of frequency-modulated high-frequency signals is reduced during reversal of the signals. This results in suppression or substantial reduction of interfering crackling noises due to phase angle rotation or a phase jump which are heard for example during VHF radio broadcasts. The process is particularly advantageous in connection with diversity antenna systems, in which phase jumps frequently occur. The invention also concerns circuit arrangements for carrying out the process.
