Patent DE-19724703-C1 (DE)
Inventor: DANIELEWSKI DIETMAR
IPC: H01R12/04

Granted: 1999-02-18
Abstract: The invention relates to a contact pin (1) enabling electrical printed circuit boards (31) to be fastened to holes (30) without soldering. The inventive pin comprises a shank section, a press-in section connected thereto and an insert section arranged on the end of the press-in section opposite to the shank section. The press-in section stands out above the contours of the shank and insert sections and has two elastically deformable contact brackets (7, 8) which can move towards each other. Each contact bracket (7, 8) has a respective wedge section (12, 13). The wedge section (12, 13) are directed towards each other in such a way that they slide on top of each other during assembly in holes (30) for printed circuit boards. The contact forces of the contact brackets (7, 8) are improved as a result of the self-regulating wedge effect, enabling advantageous gas-tight contact strips (32, 33) to be formed on two opposite-lying curvatures (28) on the edges of the contact brackets. By changing the wedge angle, the contact forces can be adapted to certain edge conditions and defined press-in and press-out forces can be produced.

Title: Process for preheating and/or drying glass-forming charge material for glass melting furnaces comprises feeding furnace waste gases through axis-parallel gas paths on opposite-lying sides of a treatment chamber
Inventor: PIEPER HELMUT
IPC: C03B3/02
Filed: 1998-07-02
Granted: 2000-04-20
Abstract: The furnace waste gases are fed through axis-parallel gas paths (14, 14a, 14b, 15) arranged on opposite-lying sides of the treatment chamber (1). The paths extend over a partial height of the tiered arrangement (8, 22).

The partial streams are united after releasing heat to the charge material on the opposite-lying side of the treatment chamber (1) to form a total stream. Process for preheating and/or drying glass-forming charge material for glass melting furnaces comprises transporting the charge material through a tiered arrangement using a vibrating movement from a conveyor path (9, 24) closed on the lower side or having an opening (11) for the charge material and surrounding an axis (A-A), and heating in a treatment chamber (1) by the waste gases from the glass melting furnace directly from above or indirectly from below by heating at least one of the conveyor paths to temperatures between 200o C and scarcely below the temperature at which the charge material has a tendency to glue together. An Independent claim is also included for an apparatus for preheating and/or drying glass-forming charge material for glass melting furnaces.

Abstract: Es wird ein motorisch angetriebener Schlegelmäher mit Fahrantrieb beschrieben, bei welchem ein Antriebskeilriemen über eine Keilriemenscheibe geführt ist, deren Keilriemenscheiben-Hälften unabhängig voneinander drehbar sind. Die eine Keilscheiben-Hälfte ist drehfest mit einem rechten Antriebsrad und die andere Keilscheiben-Hälfte ist drehfest mit dem anderen Antriebsrad verbunden, so daß sich die Keilscheiben-Hälften und somit die Antriebsräder unabhängig voneinander bei ausgeschaltetem Fahrantrieb frei drehen können. Vorzugsweise werden auf diese Weise die Hinterräder angetrieben. Es ist jedoch auch vorgesehen, zusätzlich die Vorderräder über den gleichen Antriebskeilriemen anzutreiben. Bei eingeschaltetem Fahrantrieb und straff gespanntem Antriebskeilriemen werden die beiden Keilscheiben-Hälften zusammen angetrieben und treiben dabei die beiden Antriebsräder mit gleicher Drehzahl an. Über eine weitere Antriebsriemen-Anordnung wird vom Motor eine Messerwelle gegensinnig zu der hinteren Radantriebswelle angetrieben, deren Achse parallel zu den Radachsen liegt. Der Antrieb der Messerwelle erfolgt über einen Riemenantrieb direkt, während zwischen Motor und Antriebskeilriemen ein Schneckengetriebe geschaltet ist.
