Inventor: KAADEN HANS-HEINRICH
IPC: B29C45/32
Filed: 1988-04-05
Abstract: Dans une presse de moulage par injection comportant un plateau porte-outil bissecteur, un moule d'injection est fixé des deux côtés sur ledit plateau de telle manière que la pression de serrage s'exerce directement à travers les moules sur les plaques terminales du système de serrage. A cet effet, le demi-moule est configuré comme une plaque en forme de cassette (1) qui peut être introduite dans une perforation du plateau porte-moule et positionnée sur des pièces de centrage (3). La force de serrage est transmise par des pièces de pression (6) disposées sur la surface de la plaque en forme de cassette, qui est tournée vers le système de guidage de la matière en fusion (5). Les pièces de pression des deux parties du plateau porte-moule sont disposées directement en regard l'une de l'autre, leurs faces frontales se touchant. Le système de guidage de la matière en fusion et, éventuellement, des éjecteurs individuels sont agencés dans l'espace creux entre la plaque en forme de cassette et les pièces de pression.

Abstract: Die vorliegende Erfindung betrifft eine Waage, die weitgehend 
unempfindlich ist auf Schief­
stellung und das Vorhandensein von zusätzlichen Beschleunigungen 
des Fundamentes. Sie weist zwei Kraftmesser (2,3) 
mit je einer Parallelführung (26) auf, wobei die beiden Parallelführungen 
(26) untereinander parallel sind und ihre Frei­
heitsgrade bei horizontaler Waage mit der Richtung der Schwere­
beschleunigung übereinstimmen. Der Kraftmesser (2) er­
mittelt das Gewicht des Wägegutes (M), und der Kraftmesser (3) das­
jenige (R) einer Referenzmasse (8, 22, 24). Die Waage 
weist ferner einen Rechner (4) auf, der aus den Signalen der beiden 
Kraftmesser (2, 3) die Masse des Wägegutes unabhän­
gig von der Schiefstellung und der aktuellen Gesamtbeschleunigung 
richtig ermittelt. Das Eichverfahren, das nur beim 
Hersteller der Waage durchgeführt werden muss, besteht darin, dass 
der Kraftmesser (3) bei zwei verschiedenen Neigun­
gen der Waage die Gewichtsanzeige (R₁, R₂) der Referenzmasse (8, 22, 
24), der Kraftmesser (2) die Gewichtsanzeige (N₁, 
N₂) der leeren Waagplatte (18) und die Vollastanzeige (M₁, M₂) bei 
bekannter Eichmasse (s) ermittelt. Nach entsprechen­
der Verarbeitung werden die genannten Werte - und die daraus 
gebildeten Parameter (s, S₁, P, Q, R₁, N₁) im Festwertspei­
cher (30) des Rechners (4) gespeichert. Die aktuelle Massenermittlung 
geschieht dann mit Hilfe der aktuellen Gewichtswer­
te (M, R) und der gespeicherten Grössen. 
 
  
     Abstract 
     A balance, which is virtually insensitive to angular deviation and 
to the presence of additional accelerations of the 
base, has two dynamometers (2, 3) each having a parallel guide (26). 
The parallel guides are mutually parallel and their de­
gree of freedom coincides with the direction of gravitational acceler­
ation when the balanced is horizontal. The dynamome­
ter (2) messures the weight (M) of the object to be weighed, and the 
dynamometer (3) measures that of a reference mass (8, 
22, 24). The balance also has a computer (4) which, from the signals 
emitted by the two dynamometers (2, 3), accurately de­
termines the mass of the object to be weighedindependently of the 
angular deviation of the instantaneous total accelera­
tion. During calibration, which can be carried out only by the manufacturer, 
the dynamometer (3) determines the weight 
(R₁, R₂) of the reference mass (8, 22, 24) at two different inclinations of 
the balance, and the dynamometer (2) determines 
the weight (N₁, N₂) of the empty balance pan (18) and the total weight 
(M₁, M₂) using a known standard mass. After ap­
propriate processing, the above-mentioned values and the parameters (s, 
S₁, P, Q, R₁, N₁) derived therefrom are stored in 
the read-only memory (30) of the computer (4). The true mass is then 
determined from the instantaneous values of the 
weights (M, R) and the stored quantites.

Abstract: In an injector-pump unit for diesel engines, in which an injection- pump element having a pump plunger (1) driven by a camshaft and having an element bushing (11) is combined with an injection nozzle (8) to form a unit which is to be assigned to in each case one engine cylinder, the pump plunger (1) is surrounded by a control sleeve (12), which can be adjusted in the direction of the axis of the pump plunger (1) in order to alter the beginning of injection as a function of operating parameters of the engine, the pump plunger (1) being rotatable relative to the control sleeve (12) in order to adjust the delivery quantity. The control sleeve (12) is connected to a dividing sleeve (17), which surrounds said control sleeve and is guided by its inner side on the element bushing (11) in axially displaceable fashion on both sides of the control sleeve (12). At its end facing away from the injection nozzle (8),  the dividing sleeve (17) has a hook-like extension (21) which sweeps a surface (23) lying transverse to the axis, sloping relative to a normal plane lying perpendicular to the axis and displaceable parallel to this normal plane in the direction of its slope, the adjusting force bringing about the axial adjusting movement of the control sleeve (12) acting on the sloping surface (23) and displacing the latter in the direction of its slope. As a result, a transmission for the stroke motion of the control sleeve (12) is achieved, on the one hand, control thus being sensitive and precise, and the pump plunger (1) and the control sleeve (12) are relieved of load, on the other hand, wear thereby being reduced since the guidance of the control sleeve (12) on the pump plunger (1) is to a large extent relieved of load.

Abstract: On peut introduire des hydrures de perfluorocarbone, seuls ou en combinaison avec d'autres composés de perfluorocarbone, dans un espace animal non vasculaire comme agent de contraste par l'imagerie par résonance magnétique, la scanographie ou la radiographie classique. Dans l'image que produisent ces systèmes de visualisation, le fluorocarbone que l'on a introduit dans l'espace contraste avec les autres tissus du corps. La phase gazeuse de l'hydrure de perfluorocarbone, qui se vaporise à la température du corps, se traduit à l'écran par des zones représentant des volumes vides relativement grands. De plus, la dose nécessaire de fluorocarbone gazeux est moins forte que celle requise pour le fluorocarbone liquide. Les hydrures de perfluorocarbone offrent une plus faible radiodensité dans la radiographie ainsi qu'une densité hydrogène plus faible dans l'imagerie par résonance magnétique. On décrit des applications dans lesquelles ces hydrures de perfluorocarbone peuvent servir de diluants par les bromures de perfluorocarbone, là où les composés bromés concentrés peuvent falsifier l'image produite.
