Granted: 2008-06-17
Abstract: A switching transformer applies an alternating high voltage across an internal electrode and an external electrode which face each other with a glass tube as a dielectric body between them. The anode side of a diode is connected to the external electrode which is not a voltage supply side electrode, while the cathode side is grounded. When a relay connected to both the terminals of the diode is turned on, substantially equal amounts of positive ions and negative ions are generated, and a bacteria removal/disinfection effect can be obtained by emitting these positive ions and negative ions into the air. When the relay is turned off, a relatively small amount of positive ions and a relatively large amount of negative ions are generated, and a relaxation effect given by negative ions can be obtained by emitting these positive ions and negative ions into the air.

Granted: 2010-11-30
Abstract: La présente invention a trait à en ensemble de caloduc (10/110) sous vide et chargé d'un contenu de substance active, comportant, de manière générale, un évaporateur (12/112) apte à l'évaporation du fluide caloporteur et un condenseur (16/116). Le condenseur (16/116) comprend un réservoir (30/130), situé à une élévation supérieure à l'évaporateur (12/112), pour y recueillir le fluide caloporteur liquide. Un canal de retour de liquide discret et imperméable (36/136, 20/120) permet l'écoulement par gravité de la substance active liquide depuis le réservoir (30/130) vers l'évaporateur (12/112). Le canal de retour de liquide se prolonge à travers l'évaporateur (12/112) et se termine à proximité de l'extrémité avant fermée de celui-ci, et est équipé d'un tuyau de ventilation (38/138) qui dévie la vapeur montante vers le haut du condenseur (16/116). Un élément modificateur d'écoulement (24/124) est disposé au sein de l'évaporateur (12/112), entraînant un écoulement en vortex de fluide caloporteur dans l'évaporateur, grâce à quoi l'élément modificateur d'écoulement (24/124) assure que le liquide non évaporé entraîné avec la substance active évaporée est propulsé contre les surfaces internes (23/123) de l'évaporateur (12/112) par la force centrifuge pour réaliser une couverture liquide des surfaces internes, retardant ainsi l'apparition une ébullition pelliculaire.

Title: Flying valve and well production method
Inventor: SHULYATIKOV VLADIMIR IGOREVICH
IPC: E21B43/00
Filed: 2003-04-29
Granted: 2011-08-09
Abstract: This invention relates to oil and gas production and can be used for lifting liquid from a well by gas energy.     A flying valve comprises a tubular body, a detachable element as a body of rotation and stoppers of its entry into said tubular body, with said detachable element or said tubular body or both of them being made of lubricant-resistant elastic material.   Said detachable element of the flying valve can be of spherical, tear-shaped or ellipsoid form and additionally can gave three or more flat stabilizers uniformly distributed at the periphery.   Drain ports can be made in the body wall and located on a part of its height at a level not coinciding with said stoppers, or said body wall can be made as a sylphone at the same level. On the external surface of said body there can be annular grooves with our without ring straps being placed in said annular grooves.   Straps with longitudinal grooves can be placed on the external surface of said body along the entire perimeter, or said longitudinal grooves can be made directly on the external surface of said body. On the internal surface of said body circular inserts can be placed.   Rotating contacts can be placed on external edges of said stabilizers of said detachable element. Plains of said stabilizers can be also inclined to an axis of said detachable element and their external edges can be provided with scrappers.   A method of well operation comprises a periodical run of said flying valve under a liquid level in a well up to a lower shock absorber followed by its lifting together with a liquid column being above said flying object. Said body of said flying valve and said detachable element run separately with the run of said detachable element of said flying valve following by the run of its body or vice versa.     In the first case the following relationship is to be kept:  P se/S ds < P b/S bs where P se is the weight of the detachable element, S ds is the area of diametral section of the detachable element, P b is the weight of the body and S bs is the sectional area of the body of the flying valve.     In the second case the character between the right and left sides of the inequation changes into opposite:     P se/S ds > P b/S bs If said detachable element is provided with stabilizers, then it's trip operation is carried out with said stabilizers being positioned downward.

Granted: 2014-08-19
Abstract: The present invention pertains to the field of simulating the movement of a virtual articulated object in a virtual environment. An interaction distance between a given articulated element and other articulated elements of the object is calculated; the interaction distance is extracted, a first point belonging to the given articulated element and a second point, belonging to one of the other articulated elements; a single extraction vector is defined based on the first and a second points; the given articulated element is distanced from the other articulated elements of the articulated object, according to the single extraction vector to avoid a collision between the articulated element and the other elements. The steps of calculating an interaction distance, extracting the first and second points, of defining the extraction vector and distancing the given articulated element are repeated for each of the articulated elements of the articulated object to avoid a collision between each articulated element and the rest of the articulated object.
