Abstract: A method of producing a high solids slurry of an acid-resistat precipitated calcium carbonate for shipping purposes is disclosed. A low solids of about 18 wt.% to 20 wt.% solids slurry is treated with a chemical additive, such as sodium aluminate, in order to impart acid resistance to the calcium carbonate, and is dewatered to form an intermediate solids slurry of about 44 wt%. This intermediate solids slurry is then diluted with a fraction of the low solids slurry which was treated with the chemical additive, in order to bring the intermediate slurry to a final high solids slurry of about 35 wt.%. Acid is added to the final product slurry in order to reduce the pH of the final slurry to within a buffering range of about 7.0 to 6.5. The final product slurry of about 35 wt.% comprises an acid-resistant calcium carbonate composition with a pH of about 7.0 which can be shipped for ultimate use when making paper under neutral pH conditions. The final product slurry has a Brookfield viscosity ranging from 200 to 500 centipoise at 100 rpm.

Abstract: L'invention concerne un broyeur qui comporte un conteneur rotatif (40) dans lequel sont amenés des matériaux particulaires. Le conteneur tourne à une vitesse supérieure à la vitesse critique pour former une couche qui est maintenue sous une pression élevée contre la surface intérieure du conteneur. Des disques de cisaillement (58) fixés à l'intérieur du conteneur induisent le cisaillement de la couche pour favoriser la fracture particulaire, par cisaillement et abrasion dans la couche sous pression. Les matériaux finement broyés se déplacent dans le sens axial vers l'extrémité de décharge du conteneur (64). Selon un mode de réalisation de l'invention, le conteneur tourne à une vitesse suffisante pour former une série de zones solidifiées (70) alternant avec des zones brassées (72) près des disques de cisaillement non rotatifs (58). Ces zones solidifiées agissent comme des disques solides tournant avec le conteneur.

Abstract: An object of this invention is to provide a hydraulic excavator equipped with a blade (3), which upon performing digging work by its working equipment (4), allows the working equipment (4) to be heightened in performance to such an extent as permitting full exhibition of mechanical ability with which the working equipment (4) is inherently provided as to the cutting depth. 
     Described specifically, owing to such an interference-preventing function of a controller (40) that, when a pivoted angle of the first boom (5) takes a value in a predetermined pivoted angle range before a critical angle upon conducting civil engineering works by the working equipment (4) with a truck frame (1) being directed forward, a control signal is outputted to increase a restriction of a solenoid-operated proportional pressure-reducing valve (17) as a first boom (5) approaches closer to a hazardous zone, the first boom (5) is surely prevented from being lowered excessively and interfering with the blade (3). When further digging work is required to dig deeper after digging is effected close to a maximum cutting depth Hd1 by the working equipment (4), a revolving superstructure 2 is caused to revolve over approximately 180° and a change-over switch (37) is pressed. This makes it possible to cancel the interference-preventing function, thereby permitting continuation of subsequent digging work to a maximum cutting depth Hd2.

Title: Hydraulische einrichtung
Inventor: FISCHER HELMUT
IPC: F15B11/16

Abstract: Bei einer hydraulischen Einrichtung zur Versorgung von hydraulischen Verbrauchern mit Druckmittel sind zwischen einer Verstellpumpe (1) und den Verbrauchern Ventile (7, 8) zur Steuerung der den Verbrauchern zuzuführenden Druckmittelmenge vorgesehen. Die Eingänge der Ventile (7, 8) sind miteinander verbunden. Der Druck am Ausgang den Ventile ist derart geregelt, dass die Druckdifferenz an den Ventilen jeweils gleich ist. Ein Pumpenregler (16) sorgt dafür, dass der Pumpendruck um einen festen Wert grösser als der höchste Lastdruck der jeweils angesteuerten Verbraucher ist. Zwischen dem Ausgang der Verstellpumpe und den Eingängen der Ventile befinden sich den Druckmittelfluss drosselnde hydraulische Komponenten (17, 21). Änderungen des über diese Komponenten (17, 21) fliessenden Druckmittelstroms verändern den an ihnen abfallenden Druck. Die Höhe des Differenzdrucks an den Ventilen ändert sich hierzu gegenläufig. Dabei bleibt der Differenzdruck an den Ventilen (7, 8) jeweils gleich, nur seine Höhe ändert sich. Dies führt bei Änderungen des Druckmittelstroms, insbesondere beim Zuschalten von Verbrauchern, zu einer Änderung der Verstellgeschwindigkeit der anderen angesteuerten Verbraucher. Um den Einfluss der durchflussabhängigen Änderungen der Druckdifferenz an den Ventilen zu beseitigen, ist der am Eingang der Ventile anstehende Druck dem Pumpenregler als Regelgrösse zugeführt. Derartige hydraulische Einrichtungen werden im Mobilbereich, z.B. bei Baggern, eingesetzt.
