tiel et limité, puis le serrage, des extrémités des branches de la 
monture, au moins une fente longitudinale (5) étant réalisée 
dans l'épaisseur de ladite monture, entre les drageoirs, en 
prenant naissance au miveau de la fente transversale (3) et

IPC: F02B75/02
Filed: 1984-06-07
Abstract: Die Erfindung betrifft ein Arbeitsverfahren für einen Vier­
taktverbrennungsmotor mit einem mit der Kurbelwelle in übli­
cher Weise verbundenen Kolben und einem beweglichen Hilfs­
kolben hierzu, dessen Betrieb die bekannten vier Takte Expan­
sion, Ausstoßen, Ansaugen und Kompression umfaßt. Bei be­
kannten Motoren dieser Art, die mit Hilfskolben betrieben wer­
den, wird von Kolben und Hilfskolben der Kompressionsraum 
eingeschlossen und ggfls. über die obere Totpunktlage des 
Kolbens in konstanter Größe mit abwärts geführt, wobei in 
oberer Totpunktlage bereits die Zündung erfolgen kann. Hier­
durch wird ein günstigerer Drehwinkel an der Kurbelwelle und 
damit ein besseres Drehmoment erreicht. Solche Motoren er­
zeugen jedoch stark umweltbelastende Abgase und arbeiten 
mit einem schlechten Wirkungsgrad, so daß trotz der vorge­
schlagenen Maßnahmen Drehmoment und Leistung sowie 
Verbrauch und Schadstoffausstoß in den Abgasen ungünstige 
Werte aufweisen. Dies kann bei Zugrundelegung des be­
schriebenen bekannten Viertaktarbeitsverfahrens verbessert 
werden dadurch, daß am Ende der Ausstoßphase und späte­
stens im oberen Totpunkt des Hauptkolbens der Kompres­
sionsraum vom Hilfskolben wenigstens angenähert zu Null ge­
macht und während der nachfolgenden Ansaugphase bis spä­
testens zum unteren Totpunkt des Hauptkolbens maximiert 
wird, wobei bei nachfolgender Kompressionsphase im oberen 
Totpunkt des Hauptkolbens dieser mit dem Hilfskolben einen 
Kompressionsraum einschließt, der während des nachfolgen­
den Abwärtshubes bis zu einem gewünschten Drehwinkel der 
Kurbelwelle rasch bis auf eine gewünschte Größe verkleinert 
wird, bevor die Zündung erfolgt.

Abstract: A system whereby the topography of a surface may be 
measured and recorded comprising a laser (L) producing a 
narrow beam (LO) striking the surface at point (O), a 
television camera (T) capable of detecting the angular 
bearing of the laser illuminated spot at point (O) in terms of 
three-dimensional co-ordinates (x,y, z), and a computer 
programmed to correlate signals from the television camera 
as the laser beam is scanned across the surface, thus to 
produce a reading of the three-dimensional shape of the 
surface. Such a system can be used, for example, for 
monitoring the surface topography of a stockpile of bulk
