Patent EP-0057239-A1 (EP)
Title: Monolithisch integrierte Gegentakt-Treiberschaltung
Inventor: MIERSCH EKKEHARD DR
IPC: H03K17/16
Filed: 1981-01-30
Abstract: Zur Verringerung der Störspannung, die beim Schalten einer Gegentakt-Treiberstufe in den niedrigen Ausgangspegel auf der Masseleitung (ML) aufgrund von deren Induktivität (L1) entsteht, ist zwischen den Emitter des bei niedrigem Ausgangspegel leitenden Ausgangstransistors (T3) und der Masseleitung (ML) ein weiterer Transistor (T4) angeordnet. Seine Basis ist an den einen Pol einer Referenz-Gleichspannungsquelle (URo) angeschlossen. Deren zweiter Pol ist mit der Masse-Ebene (ME) einer Schaltkarte verbunden, auf der das die Gegentakt-Treiberschaltung enthaltende Halbleiterchip über ein Substrat befestigt ist. Die Referenz-Gleichspannungsquelle (URo) hält das Basispotential des weiteren Transistors (T4) fest. Ihre Spannung ist so gewählt, daß nach dem Leitendwerden des Ausgangstransistors (T3) auch der weitere Transistor (T4) voll leitet. Wenn beim Leitendwerden des Ausgangstransistors (T3) sich infolge des Stromanstiegs eine Störspannung an der Induktivität (L1) der Masseleitung (ML) ausbildet, wird dadurch das Emitterpotential des weiteren Transistors (T4) angehoben. Da sein Basispotential durch die Referenz-Gleichspannungsquelle (UR) festgehalten wird, wird dieser Transistor weniger gut leitend. Damit kann der ihn und den Ausgangstransistor (T3) durchfließende Strom nicht so rasch ansteigen, wie das ohne den weiteren Transistor (T4) der Fall wäre. Der verlangsamte Stromanstieg bedingt aber eine verringerte Störspannung.

Abstract: In accordance with the invention, a firewood cleaving apparatus comprises a number of cleaving irons situated in four different consecutive planes, so that a block of wood, which is forced down against the cleaving irons with the aid of a ram, will be stepwise split into twelve billets. The irons in the first two planes split the block in four pieces along radial lines. The iron in the third plane is annular and yields eight pieces; while the irons in the fourth plane are radial but cleave ony the radially outer pieces that were separated from the radially inner pieces by the annular cleaving iron.

Abstract: In a positive drive power transmission system composed of a toothed belt and two or more pulleys, operating noise resulting from the impact of the belt and the pulleys is dramatically reduced by having surface discontinuities on the belt and/or on the pulleys on those surfaces where the belt and the pulleys engage in impact contact when in operation. The surface discontinuities may be formed by recessed or raised portions of the belt or pulleys, may be straight or curved, and may be substantially parallel to the tensile member or at an angle thereto. Several methods of manufacturing belts with such surface discontinuities are disclosed.

Abstract: A fuel oil atomizer (10) comprises a burner tube (12) through which fuel oil is supplied under selected pressure and a coaxial surrounding steam tube (34) providing an annular space (48) therebetween, the flow of steam being under greater pressure than the oil pressure. A burner head (22) is joined to the burner oil tube (12) through an orifice (20) of selected diameter. The burner head (22) has a long axial bore (24) of constant selected diameter, which leads to the burner tip, which has a plurality of tip ports (30). There are a number of transverse ports (44) between the annular steam path (48) and the central bore (24), so that the steam can flow under pressure into the central bore (24) of the burner head (22) to mix thoroughly with the pressurized oil flowing from the orifice (20). Two factors are important in the construction of the burner head (22), namely that the central bore (24) must be of constant diameter from the point where the steam and oil mix, outwardly toward the burner tip ports (30). Secondly, the total cross-sectional area of the tip ports (30) must be less than the cross-sectional area of the central bore (24).

Abstract: A sheet feeding assembly for a printing press including a feed table having a set of front stops and which is inclined downwardly so that a sheet travels toward the front edge of the table where it is temporarily retained in registered position. A port connected to a source of compressed air extends through the table at a position spaced from the front edge of the table. A rear feed plate is seated on the table upstream of the port and a front feed plate is seated on the table downstream of the port, the plates being substantially coplanar with their respective front and rear edges in proximity and uniformly spaced with respect to one another. The front edge portion of the rear feed plate is undercut to form an overhang which defines a transversely extending air conducting cavity which overlaps the port so that an air blast is directed at an angle upwardly and forwardly of the table to lubricate the passing sheet and to urge the sheet in the direction of the front stop. The rear plate is adjustably shiftable to vary the spacing between the plates thereby to vary the rate of discharge of the air. A manually adjustable cam elevates the front edge of the rear plate to a variably upraised position thereby to vary the angle of discharge of the air against the sheet.
