Title: method for introduction of stent in the trunk of the left coronal artery in the branch area of lateral vessel from the basilar artery
Inventor: SOKOLOV YURII MYKOLAIOVYCH
Filed: 2001-04-13
Abstract: The invention relates to medicine, namely to vascular surgery. The method for introduction of stent in the trunk of the left coronal artery in the branch area of lateral vessel from the basilar artery foresees introduction of introducer, introduction of conductive catheter by using a coronal guide, conducting through an conductive catheter to the mouth of artery of the beforehand prepared system “stent on a balloon” and conducting of it through the arterial lumen in the area of involvement to the place of implantation, positioning of stent, inflating of balloon with stent, blowing away of balloon after ending of implantation and removal of balloon from a coronal stream in an conductive catheter. Length of stent is selected and it is position so that the proximal segment of stent is disposed in the distance 0,9-1,2 diameters of mouth from the mouth of the left coronal artery, and distal segment of stent – in the distance from the mouth of lateral artery, which exceeds 2,5 diameters of lateral artery mouth. After removal of balloon from a coronal stream a coronal guide is introduce through the stent branches, located in the area of branch of lateral artery, other balloon catheter of adequate size is introduced in the mouth of lateral artery and balloon catheter is inflated.

Title: Initial perpetua mobilia of output power
Inventor: NIKOLIC LUKA
IPC: H02K53/00
Filed: 2005-10-03
Abstract: Initial perpetua mobilia of output power has a novelty in, that electric exchanges, consists from an electric motor (2) and a generator (4) as main parts, it generates energy that partially goes toward useful output power, and partially comes back to supply an electric motor (2). Conversion of mechanical energy into electrical one is carried over the circular transmitters (3) on the electric motor (2) and the generator (4). Transmitter on the electric motor (2) is of larger size. Transmitters (3) are made of light and solid material. At the initial part, the electric exchange is supplied by an external source of energy (1). When the operation of the electric exchange is stabilized and transmission of the part of energy from the generator (4) up to the electric motor (2). Time interval between the supply of electric motor (2) from the external source of energy (1) and the generator (4) is less then needed to stop the operation of electric motor (2), and stronger to produce short circuit. Working axle in electric motor (2) is made of material that maintains magnetization longer, for easier overcoming the short interval without electric supply. The same is procedure even at using one smaller and two stronger transformer stations.

IPC: C02F1/54
Filed: 2021-12-10
Abstract: La presente invención describe la designación de dos zonas de tratamiento diferentes en un gran cuerpo de agua. La primera zona es una zona de sedimentación. Esta zona se utiliza principalmente para proporcionar tratamiento y sedimentación de microorganismos y/o contaminantes para inactivar y/o retirarlas del cuerpo de agua. En esta zona se puede usar un método de desinfección basado en un índice CT y aplicar una cantidad eficaz de una composición floculante. La segunda zona es una zona de disipación. Esta zona es donde se pretende que se produzcan actividades de agua recreativas de contacto directo principal. En la zona de disipación se establece un flujo de agua que, junto con las corrientes naturales producidas por vientos y/o diferencias de temperatura de agua, generan un patrón de disipación de agua del volumen de agua dentro de la zona de disipación en la zona de sedimentación. Además, la desinfección continua del volumen de agua en la zona de disipación se proporciona preferentemente manteniendo un residuo de cloro permanente.

Abstract: 5516. Hardingham, G. G. M. March 2. Tramcars.-Variable - speed and reversing gear for tramcars such as that described in Specification No. 8150, A.D. 1894, in which each train is brought into action by tightening a corresponding brake strap, is controlled by pneumatic or electric means so as to dispense with a mechanical connection between the gearing and the controlling device. The Figures show the pneumatic arrangement. In Fig. 1, the shaft 0 of the motors M on which the gearing is mounted is coupled by chain gear to the shaft T on an air-compressing pump A which is in connection with a reservoir B. The brake levers of the high-speed, low-speed, and reversing trains are each coupled to the piston of a corresponding cylinder H', L', R', which, together with the air reservoir B, are connected by flexible pipes to the control valve D. This is placed in a convenient position for the driver, and allows any one of the brakes to be set on and kept on as long as desired. The construction of this valve is shown in Figs. 4, 4<a>, and 6. The valve casing is cylindrical, and composed of two parts a, b into which the pipes C, E, H, L, and R for the air supply, exhaust, high-speed gear, low-speed gear, and reversing-gear respectively are screwed. The valve d is mounted on a spindle f, the handle f<1> of which may be locked in any one of a series of positions by a spring catch f<3> adapted to engage in recesses in a quadrant plate ; it is divided by a central disc into two compartments d<1>, d<2>, of which d' is in communication by the ports d<1x> and a<8> and passages a<4>, c with the air-supply pipe C, while the other d' communicates by ports d<2x> <x> and b<8> and a passage b<4> with the exhaust pipe E. The pipes H, L, and R open into separate compartments of the casing, each provided with ports a<6>, b<6>, &c. facing corresponding ports in the sections d<1>, d' of the valve ; the ports are arranged so that one cylinder is always opened to the exhaust before the air supply is turned on to another. In the electric method of control, the air cylinders are replaced by solenoids connected to a switch in the place of the valve.

Abstract: 9968. Kerridge, J. H. April 21. Lighting gas by electricity. In order to keep the igniting - wire F from being heated except at the instant of ignition, one or preferably two bye-pass burners G', supplied from a common valve M, are employed, the igniting - wire F being located in one of the bye-pass burners G'. The main valve L and the bye-pass valve M are respectively pivoted to levers Q, R, which are themselves pivoted at Q<1>, R<1> to a central rod N. A third lever S, provided with a notched extension S<2>, is pivoted at S' to the lever R. When the current is sent through the electromagnet O and the igniting- wire F, one end of the lever R (which serves as an armature), and the attached lever S are lifted, whereupon the notch S<3> engages with a projection Q<3> on the lever Q, the other end of the pivoted armature lever R opens the bye-pass valve M, and the pilot jet is lit from the igniting-wire F. If the circuit through the electromagnet 0 be now broken, the armature lever R drops, and by means of the notch S<3> carries with it the corresponding end of the lever Q, and opens the main valve L, the movement of the lever R closing the bye-pass valve M after the ignition of the main burner. Extinguishing gas by electricity. The extinction of the light is effected by energizing the magnet P, which, attracting the free end of the armature lever S, releases the notch S<3> from the projection Q<3>. The weighted end Q<2> then operates the lever Q and closes the main valve L.
