Patent DE-3806363-A1 (DE)
Title: Pick arrangement
Inventor: HAUSCHOPP ALOIS
IPC: E21C27/44
Filed: 1988-02-27
Abstract: The pick arrangement according to the invention has a plate-like pick 5 which can be pushed against the cutting direction SR into a mounting pocket 11 open towards the working face 2 and in the cutting direction SR. The back 9 of the pick 5 bears over a large area against the pocket bottom 15 and a nose-like projection 16. The width of the projection 16 is adapted to the thickness of the pick 5. The torque resulting during the engagement of the pick 5 in the working face 2 is absorbed by a robust shank end 10 which engages in the mounting pocket 11 in a positive-locking manner. A clamping sleeve 21 performs the function of securing the pick 5 in position. The transversely running clamping sleeve 21 extends tangentially to the pick 5 in the top parting line between the pick 5 and the holding body 4 or projection 16. The front 8 of the pick 5 projects beyond the front 14 of the holding body 4. The extension 18 thus formed can serve to drive the pick 5 out of the holding body 4. <IMAGE>

Title: Support body for a catalytic reactor for exhaust gas purification
Inventor: BAYER JUERGEN DIPL ING
IPC: B01D53/86
Filed: 1988-12-30
Abstract: The corrugated strips used previously for the coils of support bodies must be produced in a relatively complex manner in order to avoid adjacent layers slipping into each other. The radial permeability within the catalyst is restricted. It is proposed to allow the ridges stamped out from the strip plane of corrugated sheet metal strips to project out on both sides of the strip plane. By means of suitable measures a simple method can be created for coiling two such corrugated strips having a different ridge height and distribution to give an effective support body whose surfaces to be coated are large and which is inherently radially permeable. Use for exhaust gas catalysts of internal combustion engines. <IMAGE>

Title: Method for testing the performance of small DC motors with permanent magnets in series production
Inventor: SCHEMEL ADOLF
IPC: G01R31/34
Filed: 1989-04-01
Abstract: In this test, the motor, after connection of the test voltage, is decelerated to an intended loading torque and is checked for maintenance of the set point values, the measured values being used as bases for the calculation by microprocessor assistance. To provide loading, the motor is coupled to a fan with a known loading torque, the maximum and minimum rotational speed being predetermined. Using the current/torque characteristic, the torque of the motor is calculated with fan loading, the calculated current being compared with the maximum current and from this the rotational speed of the motor being calculated.
