Patent LV-14768-B (LV)
Title: Mosfet driver
Inventor: STEIKS INGARS
IPC: H03K17/687
Filed: 2013-09-27
Abstract: The invention refers to electrical engineering and can be applied in power electronics. Its objective is to increase the efficiency of a MOSFET driver. MOSFET driver contains control block (1), capacitor (2), two fully controllable switches (3 and 5) with one resistor (6) and two DC voltage sources (7 and 8). The distinctive properties of the proposed topology are defined by the capacitor (2) connected between the control block (1) and fully controllable switch (5). The one end of the resistor (6) is connected between the capacitor (2) and fully controllable switch (5), but the other end of the resistor (6) is connected to the negative terminal of DC voltage source (7) and the negative terminal of fully controllable switch (5). In the first cycle a pulse is formed for fully controllable switch (3), therefore enabling to turn on fully controllable transistor switch (4) by applying the positive voltage between the gate and the source of fully controllable transistor switch (4). After the first pulse, another pulse is formed for fully controllable switch (5), therefore enabling to turn off fully controllable transistor switch (4) by applying the negative voltage between the gate and the source of fully controllable transistor switch (4). The connection of the capacitor (2) and the resistor (6) enables to establish a short time of the second cycle pulse and therefore decreasing the time when fully controllable switch (5) is turned on. After the second cycle the operational cycle of the driver is repeated.

Title: Ortho-lithiation process for the synthesis of 2-substituted 1-(tetrazol-5-yl) benzenes
Inventor: SHUMAN RICHARD F
IPC: A61P43/00
Filed: 1997-09-05
Abstract: A process utilizes the tetrazole functional group to direct lithiation at the ortho position of a phenyltetrazole and generate a nucleophilic aryllithium species which then undergoes reaction with an electrophile to generate a 2-substituted 1-(tetrazol-5-yl)benzene. The process is useful in the production of intermediates in the synthesis of angiotensin II antagonists. This novel process is a more cost effective and versatile route for the large-scale preparation of these key intermediates.

Title: Heart valve prosthesis
Inventor: KASJANOVS VLADIMIRS
IPC: A61F2/24
Filed: 1998-10-27
Abstract: Invention relates to medical devices and particularly to an artificial heart valve. The valve contains a circular support, three uprights and three leaves. The leaves are made of reinforced polymer threads. The support and uprights are also made of polymer threads. A central contact point of all three leaves is situated lower than tops of uprights. The reinforcement threads are placed on a surface of the leaves and they are arranged along geodesic lines. The entire prosthesis is coated by a low module polymer. Such structure provides a strength of the prosthesis and a long-term working as well as a lower risk of forming blood clogs on the surface of the valve.

Title: Extinguishing chamber for current interrupters
Inventor: GLOBIG M
IPC: H01H33/72
Filed: 1979-09-12
Abstract: A load disconnection switch incorporating a quench chamber is described which features a tube-like housing, a telescope-like arrangement of a quench tube and a switch rod guided for relative axial movement within the tube-like housing and releasably connected together by a coupling system the release of which is dependent on relative movement between the quench tube and the housing. The coupling system comprises at least one blocking device which is displaceably arranged in a respective radial guide in the wall of the quench tube and which engages in a recess provided in the switch rod. A control wall restricts the radial movement of the blocking device until, after a specified degree of relative movement between the tube-like housing and the coupled arrangement of quench tube and switch rod the restraint provided by the control wall is lifted and the ensuing relative movement of the quench tube and switch rod results in the current carrying path through the switch rod being interrupted at a spark contact and the heat generated at the spark contact causes the omission of quench gas from an associated quench rod which promptly extinguishes the arc. The spark contact is conveniently guided in an opening in the wall of the quench tube and a diametrically opposed pressure pad located at the other side of the switch rod ensures contact between the switch rod and the spark contact.
