Patent EP-0250372-A1 (EP)
Inventor: POMAR ELIODORO
IPC: F02B53/00
Filed: 1987-05-29
Abstract: The present invention relates to a rotating endothermic engine, with means for varying the com­pression ratio even during the operation, comprising a containing cylinder forming variable volume chambers, defined by the cylinder inner wall and piston side walls, the cross-section of which has substantially the shape of a circle sector. 
     During the operation, the pistons are rotated with an uneven circular motion, by means of a mechanism including a crank, having an eccentric axis with respect to that of the containing cylinder, and small coupling rods coupling the arms of the crank and the end portions of small shafts passing through the pistons. 
     The compression ratio is changed by means of a further mechanism able of changing the eccentri­city value of the crank axis with respect to the cylinder axis.   
     Preferably each engine comprises two plu­ralities of chambers, each of which is provided with a rotating motion inside a respective cylinder. 
     The construction of the assembly affords the possibility of obtaining a perfect balancing, both static and dynamic, of the masses driven in each cylinder, the fitting of a same mechanism to very different operation conditions, and a very high specific power with respect to that which may be obtained from the presently commercially available engines.

Abstract: Die Erfindung bezieht sich auf ein Verfahren zur Wicklungswiderstandsmessung einer stromrichtergespeisten Wechsel- oder Drehstrommaschine (8) während des Betriebes mittels eines Meßgleichstromes (i-U) und einer Schaltungsanordnung zur Durchführung des Verfahrens. Erfindungsgemäß wird zur Erzeugung von Meßgleichströmen (i-U, i-V, i-W) in den Phasenströmen (iU, iV, iW) der Zündzeitpunkt wenigstens eines aufkommutierenden Ventils (T6) des Stromrichters (6) um einen vorbestimmten veränderbaren Verstellwinkel (Δα) verzögert, wodurch die Stromführungszeit dieses aufkommutierenden Ventils (T6) verkürzt und die Stromführungszeit eines mit dem verzögert aufkommutierenden Ventil (T6) abkommutierenden Ventils (T4) verlängert werden, werden aus dem gemessenen Maschinenstrom (iU) der erzeugte Meßgleichstrom (i-U) und aus einer gemessenen Klemmenspannung (uU'V') der Wechsel- oder Drehstrommaschine (8) die erzeugte verkettete Meßgleichspannung (u-UV) herausgefiltert und wird aus der verketteten Meßgleichspannung (u-UV) und dem Meßgleichstrom (i-U) mittels einer Quotientenbildung der Wicklungswiderstand (R) ermittelt. Somit kann man bei einer stromrichtergespeisten Drehstrommaschine (8) während des Betriebes einen Wicklungswiderstand (R) messen, ohne dabei eine nichtlineare Widerstandsschaltung in einem Verbindungsleiter (U) zu verwenden.

Abstract: The present invention relates to a heat exchanger tube (1) having a wall thickness of less than 0.5 mm, preferably 0.3 mm, and to a heat exchanger produced therefrom. Such heat exchanger tubes (1) are technically feasible, require less material and improve the exchange of heat by comparison with tubes of greater wall thickness. However, problems arise in fastening such tubes in tube bottoms (6) which generally comes about due to widening. In order to confront this problem, the heat exchanger tubes (1) according to the invention, which have thicker walls, are either provided with two additional welded-on ends (3), which have thicker walls and are attached by means of circular welds (5), or are reinforced with insert sleeves (33). The end regions have a length of, for example, 5 cm and can easily be mounted in tube bottoms (6) using conventional methods. <IMAGE>

Abstract: The device has a working tube (1) which can be pressed forward in the direction of the through-bore and an extracting unit (3) which is mounted in this working tube (1) and has a selective-cut extracting tool (7) which can be pushed axially backwards and forwards in the working tube (1) and can be moved radially relative to the axis of the latter. When the extracting tool (7) is not extended radially, the entire extracting unit (3) has a substantially smaller cross-section than the inner cross-section of the working tube (1). A conveying trough (19) arranged at the base of the working tube (1) and having a receiving opening of shovel-like design provided at its front end is used for the simple and inexpensive removal of the earth loosened by the extracting tool (7). The conveying trough (19) is first of all pressed forward into the working tube by means of a drive mechanism (21, 22, 23, 24) in order to receive loosened earth and is then pulled out of the working tube (1) to the rear, emptied and moved into the working tube (1) again.

Abstract: In catalytic heating panels for the combustion of a burnable gas with oxygen or air and with separate supply for the burnable gas and the oxygen, there is the problem that the combustion, both in the combustion of hydrocarbons and in the combustion of hydrogen, is incomplete and small burnable-gas residues remain in the waste gas. To ensure complete combustion of the burnable gas, it is envisaged that the burnable gas flows, separately from the oxygen, through a diffusion layer (12) in a catalytically active layer (10) arranged on the opposite side of the diffusion layer and that the catalytic activity of the catalytically active layer is greater on the side facing away from the diffusion layer (12) than on the side facing towards the diffusion layer. <IMAGE>
