Abstract: Cellulosic pulp is treated to obtain simultaneous pulp flow and consistency control, utilizing a pressure-tight vessel (10) having a pulp inlet (12), pulp outlet (13), treatment liquid inlet (26), liquid extraction outlet (17), and movable screen (18) adjacent the liquid outlet (17). Pulp is fed into the pulp inlet (12) at a particular flow rate, and treated pulp is withdrawn through the pulp outlet (13) at a particular flow rate. The flow rate of the pulp being withdrawn is set and controlled by controlling the flow rate of the pulp fed into the pulp inlet (12). Liquid is withdrawn through the liquid outlet (17) at a particular flow rate, and the consistency of the pulp being withdrawn through the pulp outlet (13) is set and controlled by controlling the flow rate of liquid from the liquid outlet (17). Treatment liquid is fed into the liquid inlet (26), the nature of the pulp treatment and the qualities of the pulp being controlled by controlling the temperature and chemical makeup of the pulp introduced into the liquid inlet (26). A plurality of vessels (10, 10 min , 10 sec ) may be provided with the pulp withdrawn from each vessel fed to the subsequent vessel, and the liquid withdrawn from each vessel fed to the preceding vessel.

Abstract: A variable point position determining arrangement includes a housing having a stationary portion secured to a fixed member as, for example working cylinder, and an extendable portion secured to a member movable in relation to the fixed member, as for example piston rod. An elastic element, such as a tension spring, is connected between the stationary portion and an extendable portion of the housing. Such elastic element is stretched or relaxed an amount proportionate to the travel of the movable member. The displacement transducer having an actuator rod and a projecting pin connected to the elastic element at approximately a middle point, follows movement of the elastic element and outputs a distance signal which is a function of the movement of the actuator rod and elastic element. The distance signal can be fed to a control circuit to derive the position value of the movable member therefrom.

Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control syytem (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal. is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.

Abstract: A process for the preparation of 2-hydroxy-4-methylthiobutyric acid. 2-Hydroxy-4-methylthiobutyronitrile is hydrolyzed with mineral acid to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid and substantially free of unreacted 2-hydroxy-4-methylthiobutyronitrile and 2-hydroxy-4-methylthiobutyramide. 2-Hydroxy-4-methylthiobutyric acid is recovered from the hydrolyzate by extraction. Extraction may be carried out without prior separation from the hydrolyzate solution of any substantial fraction of solids present therein, and 2-hydroxy-4-methylthiobutyric acid may be recovered from the extract by steam distillation. The extraction solvent has a boiling point of between about 60 DEG C and about 200 DEG C, and the distribution coefficients for 2-hydroxy-4-methylthiobutyric acid between extract and raffinate, and between extract specimen and wash water, favor transfer to and retention of the acid product in the organic phase.

Abstract: A cross-country ski binding for use with a ski boot having a front extension portion on its sole, with the front end portion providing a hooking area on its top surface, has a double-armed retaining lever whose arm which faces towards the rear of the binding forms a hook for engaging behind the hooking area on the extension portion of the boot. The second arm of the retaining lever can be secured in the closed position of the binding by a locking lever pivotally mounted at the front end of the binding. The locking lever is spring-loaded towards the position of locking the retaining lever in the closed condition of the binding. The binding also has a release button which is disposed pivotally coaxially with respect to the retaining lever and which is limitedly pivotable relative to the retaining lever, against the force of a retaining spring, thereby to displace the locking lever into a position for releasing the retaining lever. The retaining lever also has an abutment which is engaged by the first extension portion of the boot upon insertion thereof into the binding to pivot the retaining lever into the binding-closing position.

Abstract: This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or polyurethane, which involves first providing an aqueous solution (continuous phase liquid) containing an emulsifier which is a water soluble, alkylated polyvinyl pyrrolidone polymer which will form a stable oil-in-water emulsion under the process conditions described herein. A discontinuous (immiscible or organic) phase liquid containing a water-immiscible material which is the material to be encapsulated, plus a first shell wall component; is dispersed in the aqueous liquid to form an oil-in-water emulsion. The second shell wall component is added to the oil-in-water emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polycondensate shell wall about the material to be encapsulated. The capsules formed may be directly used as in the form of an aqueous suspension.
