Выявляют диапазон температур проявления флюидов в кварце из песчаников, учитывают температуры фундамента. Если обнаруживают наличие более высоких значений температур в вышележащих осадочных породах, чем в породах фундамента, делают вывод о воздействии горячих флюидов. Если детектируют в кальците наличие высокомолекулярного органического соединения – нефти, делают вывод о привносе нефти флюидами из пород фундамента в купольные структуры осадочного чехла. Технический результат: снижение трудоемкости и повышение достоверности определения миграции залежей углеводородов в купольных структурах. 14 ил.

Abstract: An injection-molding apparatus has a nozzle extending along an axis and formed with an axially forwardly opening outlet, an annular port fixed immediately axially behind or upstream of the outlet, and a central axially forwardly opening port axially fixed behind the annular outlet. Respective plastifiers for feeding respective plastified synthetic resins, normally thermoplastics, are connected to the respective ports. An axially displaceable valve body in the nozzle is displaceable from a fully forward position blocking both of the ports, through a partially back position blocking only the central port, to a fully back position clear of both of the ports. Thus in the fully forward position no resin can enter the nozzle, in the partially back position resin can enter the nozzle only from the annular port, and in the fully back position resins can enter the nozzle through both of the ports.

Abstract: An apparatus adapted to be mounted on a surface grinding machine is provided for testing abrasive grains in single-grit scratch tests. To permit specimen preparation and scratching to be carried out on a single machine without changeover and without reclamping the specimen, and to maintain the infeed in the scratching operation constant by giving the specimen a contour corresponding to the cross-feed error, a belt grinder and a scratching device comprising a support disk, mounted by means of a main flange and a counterflange, and a scratching disk mounted on the main flange and carrying a single grain secured to its periphery along with a force-measuring system disposed thereunder, are designed as a structural unit adapted to be mounted on the spindle of the surface grinding machine, with a belt tensioning arm mounted to the headstock. The requisite natural frequency of the force-measuring system is obtained by locating a grain holder, a piezoelectric quartz crystal and a necked-down titanium bolt with rapid-acting tightening means on the rotating scratching disk beneath the abrasive grain.

Title: Hydraulische Servolenkung für Fahrzeuge

Filed: 1981-06-25
Granted: 1988-08-18
Abstract: Die hydraulische Servolenkung für Fahrzeuge besitzt eine zusätzliche, hydraulisch beaufschlagte Arbeitsvorrichtung. Die eigentliche (hydrostatische) Lenkung enthält ein Steuerventil (6) mit einem in Neutralstellung des Steuerventiles offenen Steuerkanal (16). Durch diesen Steuerkanal fließt bei Neutralstellung des zu der Arbeitsvorrichtung gehörenden Schaltventiles (10) ein Pilotstrom, der zur Anregelung des Arbeitsdruckes der Lenkeinrichtung dient. Bei verstelltem Schaltventil (10) fließt über den Steuerkanal (16) der Rücklaufstrom von dem Arbeitsmotor (11) der Arbeitsvorrichtung. Sobald bei einer Lenkbewegung das Steuerventil (6) verstellt wird, wird der Steuerkanal (16) in zunehmendem Maße abgesperrt. Dadurch wird einerseits der Arbeitsdruck angeregelt und andererseits der Rücklauf von dem Arbeitsmotor (11) gedrosselt und schließlich ganz abgesperrt. Der Arbeitsmotor (11) wird somit blockiert, wenn das Steuerventil (6) voll verstellt ist, weil die Lenkung den gesamten Ölstrom benötigt. Die Lenkung wird also im Bedarfsfall vorrangig mit Druckmittel versorgt, wobei sich der Arbeitsmotor (11) nicht unkontrolliert bewegen kann. Ein Auftreten von Kavitation im Arbeitskreis wird durch die Absperrung des Rücklaufstromes von der Arbeitsvorrichtung durch das Steuerventil (6) des Servolenkkreises (1) verhindert.
