  • Publication number: 20210123459
    Abstract: A hydraulic valve includes an on/off seat-type main valve with two ports having a displaceable poppet for opening and closing the main flow channel; an on/off seat-type pilot valve with three ports, with a magnetomotive force producing coil, a magnetic circuit, and an anchor movable with the magnetomotive force produced by the coil; and a frame with required channels and spaces for the poppet and for the anchor. Closing the inlet channel displaces the poppet and opens the main flow channel. Opening the inlet channel forces the poppet to close the main channel. The anchor includes a frame with a first sealing element for closing the low-pressure outlet channel of the pilot valve and with a second sealing element for securing the closing of the high-pressure inlet channel of the pilot valve. The sealing surface of the second sealing element is movable in relation to the frame of the anchor.

  • Publication number: 20190376885
    Abstract: A force sensing probe (100) for sensing snap-in and/or pull-off force of a liquid droplet (111) brought into and/or separated from contact with a hydrophobic sample surface (151), respectively, comprises: a sensing tip (101); a sensor element (102) connected to the sensing tip, capable of sensing sub-micronewton forces acting on the sensing tip in a measurement direction; and a droplet holding plate (104) having a first main surface (105) and a hydrophilic second main surface (106) connected via a peripheral edge surface (107), and being attached via the first main surface to the sensing tip (101) perpendicularly relative to the measurement direction for receiving and holding a liquid droplet (111) as attached to the second main surface; the droplet holding plate comprising an electrically conductive surface layer (115), the first and the second main surfaces and the peripheral edge surface being defined by the surface layer.

  • Patent number: 10329505
    Abstract: The present invention relates to a method for manufacturing a biofuel from a vegetable-based biomaterial by performing the manufacture in an integrated manner, in such a way that the biomaterial is made finer and dried with the aid of heat brought from a heat-releasing process, when the drying is finally performed after the finer making stage, optionally in such a way that drying is started already in connection with finer making. The invention also relates to a biofuel manufactured in this manner and the use of the fuel in question.

  • Patent number: 10240259
    Abstract: A method of manufacturing a cellulose-based shaped article. The method comprises subjecting a solution of lignocellulosic material, dissolved in a distillable ionic liquid, to a spinning method, wherein the ionic liquid is a diazabicyclononene (DBN)-based ionic liquid. DBN-based ionic liquids have good dissolution power, high thermal and chemical stability, lack runaway reactions and exhibit low energy consumption, due to low spinning temperatures. The shaped cellulose articles can be used as textile fibers, high-end non-woven fibers, technical fibers, films for packaging, and barriers films in batteries, as membranes and as carbon-fiber precursors.

  • Publication number: 20190060969
    Abstract: The present invention relates to a method and tools for manufacturing of seamless tubular shapes, especially tubes and canisters. In the method of the invention the tubular shape is extracted from the flash (1) continuously produced during the plunging of a consumable rod (2) against a rigid anvil (3). The tools of the invention include a consumable rod (2); a non-consumable or consumable rigid anvil (3); first means for rotating the consumable rod (2) and the non-consumable or consumable rigid anvil (3) relatively with respect of each other; second means for plunging the consumable rod (2) and the non-consumable or consumable rigid anvil (3) relatively against each other; open die condition configuration for continuous production of flash (1) during said plunging.

  • Patent number: 10000614
    Abstract: The present invention concerns a method of preparing a film of nanofibrillated cellulose (NFC) on at least one surface of a support material, wherein the film is applied and spread directly onto a surface of the plastic support material in the form of a suspension of nanofibrillated cellulose, whereby the nanofibrillated cellulose forms a film. Further, the invention concerns a structure containing or consisting of a film of nanofibrillated cellulose prepared using said method.
