Title: Biomass solid fuel
Inventor: HAYASHI SHIGEYA
IPC: C10L5/08
Filed: 2015-10-07
Abstract: The present invention relates to biomass solid fuels.

Title: Method of controlling centrifugal separator and centrifugal separator
Inventor: KÖNIGSSON STAFFAN
IPC: B04B13/00
Filed: 2019-12-09
Abstract: Herein a centrifugal separator (1) and a method (100) of controlling a centrifugal separator are disclosed. The centrifugal separator (1) comprises a rotor (11) delimiting therein a separation space (6), an inlet (8) for liquid feed mixture, a first outlet (10) for heavy phase, a second outlet (9) for light phase, and at least one channel (16, 16’) extending towards a central portion of the rotor (11). The method (100) comprises steps of: - separating liquid feed mixture into at least the heavy phase and the light phase in the separation space (6), and - determining at the first outlet (10) that a pressure build-up period has passed, and thereafter - determining that an abrupt pressure change takes place at the first outlet (10), and - controlling the centrifugal separator (1) in response to the abrupt pressure change. By controlling the centrifugal separator in response to the abrupt pressure change at the outlet, e.g. to open the heavy phase outlet, the separator prevents escape of the mixture prior to separating or blockage of the outlet from the build up of separated heavy phase after separating has commenced.

Title: Low-torque water shutoff-type line stopping valve using stepwise pressure point support
Inventor: KIM JAE HYUN
IPC: F16K3/314
Filed: 2019-08-20
Abstract: The present invention relates to a low-torque water shutoff-type line stopping valve using stepwise pressure point support, and method for enabling construction without shutting off water when a pipe is replaced or repaired. It is known that foreign material is inevitably generated on the inner wall inside a pipe as time passes, and the foreign material is unavoidably generated during an operation such as pipeline repair due to external impact applied to the pipe which can cause water stopping performance degradation. However, the disc, according to the present invention, is supported while removing the foreign material formed on the inner surface of the pipe, so as to improve support power and airtightness since, when the disc comes in contact with the inner side of the pipe so as to block a flow path, first two points come in contact with and are supported by the inner surface of the pipe, and then the two points supported by pressure sweep the inner surface of the pipe outward, thereby finally achieving surface contact with and support by same, and protrudes to support the pipe in the center after making surface contact and being supported, thereby enabling airtightness to be more improved. The rubber member in the disc of the present invention comprises a perforated area closing part inserted into the hole of the pipe so as to perform a closing function, and an inner area blocking part configured to extend in the downward direction of the closing part and to have a narrower width than the closing part so as to cut off the inside of the pipe; wherein the inner area blocking part is formed to bend along the inner shape of the pipe, and includes a sweeping groove part configured to be concave in a V-shape and formed on an entirety of an inner pipe-engaging surface that is oriented perpendicular to a longitudinal axis of the pipe and along one side of the inner pipe-engaging surface that is oriented parallel to the longitudinal axis of the pipe; The disc of the present invention also comprises an auxiliary groove part (24a) and a sweeping groove part (12a). The present invention reduces the power required for water stopping to be lower than that of a conventional disc so as to be capable of stopping water by using lower torque; and improves water stopping performance.

Title: Sewing-machine needle and process for manufacturing it
Inventor: TAKEI YOSHITSUGU
IPC: B21G1/04
Filed: 1992-06-26
Abstract: Sewing-machine needle 62, including a cylindrical shaft 12, a blade 14, 16, and a sharp needle point 60, formed at a more remote end of the said blade, on which a long and continuous concave-shape groove 28 is provided in such a manner as to be extended from the said shaft 12 as far as a portion of the said blade 14, 16, close to the said needle point 60, a needle hole 30 being formed along the said long groove 28 and the said blade being formed with a clearance 40 above the hole, which is manufactured without producing any burr on a blade, subjecting the entire blade to die-pressing. An unfinished needle 10 is subjected to double stamping, the result being the formation of blade sections 14, 16. The unfinished needle is then formed with an elongate portion in order subsequently to form a clearance 40 above the hole, in front of a needle hole 30. Die-pressing allows both the lateral surfaces of a long groove 28 to be spaced from one another by a predetermined angle and the clearance 40 above the hole and the hole portion 30 to be formed. The sewing-machine needle 62 thus formed has sufficient stiffness and a larger space between the blade and the sewing line, resulting in a sewing operation carried out with stability and with greater speed. The present invention is applicable to the sewing-machine- needle industry. <IMAGE>

Abstract: FIELD: conversion equipment. SUBSTANCE: transformer may find use in high-frequency voltage converters for stabilization of output voltage. In compliance with invention choke without air gap and transformer are structurally integrated in one electromagnetic element. Its magnetic core is composed of three toroidal strip legs of magnetic material with narrow major hysteresis loop simultaneously embraced by turns of primary winding. Each leg has different number of turns in agreement with expression W≥ 2W; W≥ 2W, where Wis number of turns embracing k=1, 2, 3 legs of windings of separation of legs by reverse magnetization current connected in series aiding and to reactive resistance. Stabilization of voltage is performed by average value of output voltage which is picked off from output winding embracing first leg. Accuracy of stabilization is determined by horizontally of sections of major hysteresis loop.
