Abstract: Filter for fibrous material is disc type and has hollow shaft down which passages run. A series of segmental discs are located along the shaft with each segment having a passage which connects with the passage down the shaft. A distributor valve permits alternating press. and suction to be applied to various passages as the shaft rotates. - This distributor valve establishes a suction zone around a certain sector, this being divided into parts. The first serves to draw off the so-called dirty filtrate while the second draws off the clean filtrate. Suction in the clean zone commences somewhere between the lowest posn. of the radius and 60 degrees round from this esp. in a zone 10-50 degrees round from the lowest posn. Suction for the dirty filtrate commences at least 45 degrees before the lowest posn. - Used to filter fibrous slurries esp. wood pulp slurries inppapermaking. The filter operates significantly quicker and more precisely than previous disc filters.

Abstract: By forming current jump or surge signals and voltage jump or surge signals, in accordance with the changes as a function of time of the line current and line voltage in relation to the steady-state course of the current and voltage and comparison of such jump or surge signals with a threshold value, dependent upon the other jump or surge signal, or an appropriate threshold value function, there can be derived trip boundaries in the surge signal plane. Exceeding such trip boundaries in a direction from the inside towards the outside can be utilized as a fault criterion for producing a trip signal. With suitable trip boundaries, at least inclined in sections towards the coordinate axes owing to the aforementioned dependency of the comparison threshold values, which trip boundaries also may be curved, and arranged in spaced relationship from the coordinate-null point in the four quadrants of the surge signal-coordinate system there is realized a rapid fault detection which is comparatively foolproof against faulty tripping and by determining the quadrants where there occurs the initial exceeding of the threshold value, there likewise can be realized an equally rapid and positive fault-direction detection.

Abstract: Contamination between successive aqueous samples in a continuous-flow analytical system is eliminated by the careful and precise application of a thin, uniform film of immiscible fluid upon the outer surface of an aspirating probe of a metering system. The immiscible fluid is selected to preferentially wet the inner and outer probe surfaces and the inner wall surfaces of the conduits of such system, to the substantial exclusion of the aqueous samples. The immiscible fluid is aspirated, along with an air segment, between aspirations of successive samples, each aspirated air and sample segments are encapsulated by such immiscible fluid while passed through such system. A selective valve is utilized to isolate and transfer each fluid sample from the probe to such system.

Abstract: A fluid engaged and spring returned fan clutch for connection with a live rotative source of power including an annular mounting flange for connection with the source of power. The mounting flange terminates in a hub. Also included is an annular friction flange connected to the hub. A first outer shell section is rotatively mounted on the hub and connected to a second outer shell section with fan blades connected thereto. A circular face plate is connected to the second outer shell. A circular piston is axially and slideably mounted on and within the second outer shell section and axially of the face plate thereby forming a cylinder void between the piston and the face plate. A circular resilient bladder member is secured at its peripheral edge portion between the second outer shell section and the face plate with the bladder adjacent the piston and opposed to the face plate. The piston has a ring of friction material connected thereto. A series of spaced springs are mounted between the first outer shell section and the piston for urging the ring of friction material from the friction flange. Fluid pressure is introduced by means of a rotary air union into the cylinder void between the face plate and the bladder to cause the friction material ring to engage the friction flange to thereby rotate the first and second outer shell sections and the fan blades carried thereby against the action of the springs.

Abstract: The thermodynamic energy conversion plant converts air energy into heat or mechanical force, and works on the basis of a reversible, thermodynamic cycle without a chemical carburettor. With it, it is possible to mechanically compress a work medium and not allow it to expand. This means that it works in accordance with a constant pressure principle, without allowing heat to reach the work medium. The plant approaches the concept of a perpetual mobile, having reversibility without fluid-dynamic exchange, work without gas expansion and mechanical energy produced by heat corresp. always to a quantity of heat lost as the product of work.
