Patent SE-7805001-L (SE)
IPC: B02C15/04
Filed: 1978-05-02
Abstract: A process, as well as a device for carrying out same, for grading-separating wet milling of rocks and the like in a mill having a vertical rotational shaft, a milling chamber widening downwards and outwards from a central outlet and one or more milling rollers interacting with the milling chamber, the replenishment of the pulp being done through constant feed. The pulp volume is regulated by displacing the upper edge of the outlet vertically, whereby control of the milling time is achieved so that particles can be kept a longer or shorter time in the milling chamber depending on the milling resistance and structure of the material fed in, thereby effecting a control according to particle type for continued milling of particles which are not completely milled, for example mineral-containing particles, and for discharging from the milling chamber completely milled particles and mineral grains. In the device, the milling chamber is separable from the central outlet at a selected height by means of a regulating member, for example a vertically adjustable shield. The device is provided with at least one wave dampener controlling and active in the surface layer of the pulp. The dampener is preferably a screen or water curtain.

Abstract: The invention is a procedure for continual composting of compostable material in a container in which material is made to pass through the container from the top down from an upper level in such and a medium containing oxygen gas, which is necessary for microbiological breakdown, flows through in a counter stream to the material. The invention is unique in that the departing gas is drawn from a zone below the upper level in the container with a pipe, nozzle or the like that extends into the zone, whereby a negative pressure is established in the pipe/pipes or nozzle/nozzles so that the medium containing oxygen gas is also brought to flow in the same direction as the material in the container from the upper level in such to the zone in question.<IMAGE>

Abstract: An antiskid control system for the individual regulation of fluid brake pressure at the respective wheels of a vehicle. The control system is modified so that a steering wheel experiencing high wheel/road adhesion is co-controlled during a cycle of wheel skid control at the steering wheel experiencing a low wheel/road adhesion value, such co-control being delayed at the onset of brake release at the low adhesion wheel, while the high adhesion wheel brake pressure is maintained constant to improve stopping distance.

Abstract: A wave motor for propulsion of a floating device, especially a watercraft, comprises a downwards extending supporting structure connected to the craft. An essentially horizontally disposed, plate-like tilting element, at a forwrad portion thereof as viewed in the cruising direction, is pivotally connected to the lower end of the supporting structure. This arrangement results in a tilting movement as a result of relative movement between the tilting element and the surrounding water when the craft is floating on the water and is raised and lowered due to wave action, the tilting movement being limited by upper and lower stops arranged on the supporting structure. The supporting structure is arranged to effect an essentially vertical, relative movement in relation to the craft, and is maintained in an intermediate position and returned to this position when it has been moved away from the intermediate position by influence of wave forces.

Abstract: The invention relates to a device for insuring the tight seal of a closed space filled with a gas at high pressure through one wall of which an outlet rod is positioned, said outlet rod being subject to reciprocating rectilinear movement. Between the walls of the closed space and the outlet rod, two dynamic seals and a rolling diaphragm are successively positioned. Between these two seals, the outlet rod has a shoulder such that in combination with two non-return valves, it acts as a pump which sucks the gas from the chamber formed by the intermediate seal and the rolling diaphragm and delivers this gas to the closed space, thereby maintaining a relatively low pressure on the rolling diaphragm despite leakage of the seals and valves. This invention is particularly applicable to Stirling engines.

Abstract: Alpha gypsum hemihydrate is obtained by calcining calcium sulfate dihydrate, generated with flue-gas desulfurization of power plants or by chemical process, e.g. in the production of phosphoric acid. The calcining process comprises producing initially a dispersion from calcium sulfate dihydrate and diluted, sulfuric acid solution and heating same at a predetermined rate to about 373 K with industrial, dust-free waste heat, whereupon the solid components are separated from the aqueous sulfuric acid and are dried. An alpha gypsum hemihydrate practically free from anhydrite II is obtained from a solution of sulfuric salts in the diluted sulfuric acid. An addition of magnesium oxide yields a hemihydrate with a high degree of fineness and avoids blooming effects.

Abstract: The process is for measuring an object with two side surfaces which is illuminated by at least one radiation source. The radiations reflected on the object are picked up by two detectors fitted over it. The detectors produce electrical signals proportional to the picked-up radiations, which are fed to an electronic evaluation unit. The measurement object (10), through individual sweeps, (A) is investigated along a stretch comprising a sweep area, using a bunch of radiations moving at an adjusted speed. Each of the detectors (22') with their vision fields (22A) cover each side surface (10b,10c) and the whole of the upper surface (10a) of the object, and produce a signal sequence. The evaluation unit provides as an indication of the measurement sweep one end point and the signal sequence's first passage from values below a set threshold value to those above it.
