Title: Process for the concentration of fibrous materials
IPC: C03B37/10
Filed: 1981-02-02
Abstract: Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by subjecting an aqueous suspension of the mixture to centrifugal force in a hydrocylone to obtain an overflow enriched in fibre and an underflow of reduced fibre content, the aqueous suspension which is admitted to the hydrocylone being the fibre-enriched fraction which results from a preliminary classification in which an aqueous suspension of lowerfibre: non-fibre ratio is submitted to flow under conditions which bring about settling out under ordinary gravitational force of material reduced in fibre content and formation of a fibre-enriched fraction above it.In the process, the underflow flow from the hydrocyclone is incorporated in the aqueous suspension which is submitted to the preliminary classification.The process, which keeps to a minimum the amount of valuable fibre lost, is specially applicable to the concentration of fibres in the fibrous products (mineral wool) formed by disintegrating silicate and like mineral melts, which commonly contain relatively high proportion of granular material ('shot').

IPC: B01D11/02
Filed: 1982-04-20
Abstract: A multi-phase separation process which is particularly 
useful in connection with the cleaning of cuttings resulting 
from conventional oil drilling techniques.  
     A mixture of carrier liquid (sea water), a contaminant li­
quid (oil) and solids cuttings is passed over the screen of a 
screen bowl centrifuge while simultaneously washing the mix­
ture with further sea water whereby a finer portion of the solids 
particles is washed through the screen taking with it the con­
taminant liquid oil which has been washed off the solids by the 
sea water and which adheres to the finer solids particles, 
thereby leaving the remaining, larger solids particles substan­
tially free of oil of the "available" type which adheres to solids 
particles by surface tension forces only and can therefore be 
detached from such particles solely by immersion or washing 
in the carrier liquid.  
     Separation of the finer solids particles from the sea water 
carrier liquid is achieved in a secondary centrifuge.

Abstract: Es wird ein Verfahren zur Bestimmung der Aktivität des 
Kohlenstoffes in Ofenatmosphären o.dgl. beschrieben, bei 
dem das Partialdruckverhältnis des Sauerstoffes im Ofengas 
gegenüber einem Vergleichsgas mit Hilfe der von sauerstof­
fionenleitenden Feststoffzellen abgegebenen elektrischen 
Spannung festgestellt wird. Dabei wird als Vergleichsgas das 
Ofengas vorgesehen, das bei Ofentemperatur mit Kohlen­
stoff ins Boudouard-Gleichgewicht gebracht wird. Es wird 
außerdem dafür gesorgt, daß der Gasaustausch in der 
Vergleichsanordnung mit einer Zeitkonstanten von 1/10 der 
des Ofens stattfindet. Es wird dann der Vorteil erreicht, daß 
sich die Aktivität des Kohlenstoffes nach einer Formel 
berechnen oder eichen läßt, in der zwar die von den 
Feststoffzellen abgegebene elektrische Spannung und auch 
die absolute Temperatur enthalten ist, jedoch nicht der 
CO-Gehalt und auch nicht der Druck. Das neue Verfahren 
kann daher ohne Berücksichtigung des CO-Gehaltes in der 
Ofenatmosphäre arbeiten und vermeidet damit die Nachteile 
der bekannten Meßverfahren.

ceeds the tractor (1) steering angle, activates the hydraulic 
circuit connecting the two pistons (13; 14) to prevent said 
angle from increasing.

Abstract: A contactless proximity switch and mounting arrangement for determining the position of a movable member within a cylinder which has two end covers secured on the cylinder by means of a plurality of tie rods, includes a switch housing which secures to one of the tie rods. A contact opening formed in the switch housing has disposed therein, a switch having a pair of contacts and a permanent magnet disposed in a fixed manner.

Patent EP-0226148-A3 (EP)
IPC: H01L29/78
Filed: 1986-12-05
Abstract: A current limited insulated gate transistor 
(IGT) is disclosed wherein the individual cells are 
rectangular and each has four discrete, mutually spaced 
emitter regions to provide a reduced gate periphery. 
Each cell lacks emitter portions at the cell corners to 
reduce current crowding in the corner areas. The size 
of each cell is kept small to decrease the forward 
voltage drop of the IGT at its operating current level 
and the spacing between individual cells of the IGT is 
minimized in order to further reduce the maximum IGT 
current. These features enable the cell to survive a 
short-circuit load condition by preventing the maximum 
current from reaching the latch-up level.

applications where it is desirable to eliminate the use 
of rectifying means to lower the effective voltage 
across the filament.
