Patent LT-7007-B (LT)
Title: Five degrees of freedom piezoelectric drive
Inventor: MAŽEIKA DALIUS
IPC: H02N2/00
Filed: 2022-12-08
Abstract: The invention discloses a high-precision piezoelectric drive which generates independent rotary motion of the spherical rotor about three axes and sliding motion in the plane, and improves the dynamic characteristics and control of the drive. The drive consists of two piezoelectric rings (2, 8) fixed on elastic supports (5, 10) mounted on elastic rings (4, 7), and connected by an elastic cone (6). Three spherical contacts (3, 9) are installed on both piezoelectric rings and are used to rotate the rotor (1) or move the system on a flat hard surface. An asymmetric electric signal is used for excitation. The dynamic characteristics are increased when the resonant frequency of the support coincides with the resonant frequency of the bending vibrations of the ring. The location of the supports corresponds to the vibration nodes of the piezoelectric ring. Control of the rotational and sliding movement of the piezoelectric drive is improved by the use of a cone-shaped stator that allows reducing of the transmission of vibrations from the upper ring to the lower and vice versa.

Abstract: A beverage cask or container 1 has a bung hole outlet housing 2 within which is located a body 4 carrying a liquid extractor tube 9 and a valve means 17,18,19 which cooperates with a top fitting (not shown) to open passageways for introduction of gas A and extraction of liquid B. The body 4 and valve means is retained by a top plate 15 of which the marginal edge portions 16 have been deformed to form a "clench" around the flared top 3 of the housing 2. The clenched top plate forms the sole means of retaining the valve and body assembly in position. The dimensions of the clenched plate 15 are such that the top fitting (not shown) may be directly coupled therewith and the plate further forms an integral constructional part of the valve means being a seating surface for seal 17. The arragement provides security as it is necessary to cut-away the plate 15 to gain access to the container but nevertheless the plate can be fitted and removed easily using appropriate equipment. The need for providing threading on the outlet 2 to secure body 5 is avoided.

IPC: B04C11/00
Filed: 1985-04-24
Abstract: The invention relates to a method of controlling an apex flow in a hydrocyclone unit (9), and a control system for carrying out the method. The hydrocyclone unit (9) comprises a plurality of hydrocyclone separators (10) in parallel, and further comprises an inject chamber (21, 22, 23), base chamber and apex-fraction chamber common to all separators, an inlet (1) to the inject chamber (21) and an outlet (2, 3) for the base chamber (22) and apex chamber (23) respectively. The apex flow is controlled by automatically and substantially continuously detecting at a location in or adjacent the apex outlet (1) a flow parameter of the apex fraction, and comparing this sensed flow parameter value with a set-point value, and changing the setting of a valve (15) incorporated in a conduit (14) connected to the apex outlet (2) when the sensed value deviates from the set-point value, so that the flow parameter value of the apex fraction moves towards the set-point value.

Abstract: 1,135,974. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 14 Nov., 1967 [23 Dec., 1966], No. 51830/67. Heading G6C. In a molten sodium cooled fast reactor, the core and heat exchangers are mounted within a pressure vessel. In order to interrupt the flow of coolant through one or more of the exchangers without interrupting the circulation through the remainder, an inert gas is injected into the upper volume of the selected exchangers. The gas forms a coolant free surface within the exchanger and acts against the pump pressure to prevent the coolant inflow to the exchanger. The core 8 is cooled by sodium circulated by pump 42 through the exchanger 24. The sodium enters 24 through the inlets 28 and flows downwards to the outlets 30 and to arrest coolant flow, argon gas is injected into the bell casing 46 through the pipe 48. A free sodium surface is established in 26, Fig. 3, and coolant entry through the inlets 28 ceases. Convection cooling occurs when the pumps are not operating.

Abstract: The invention refers to a navigation device for the execution of necessary navigation course determinations. Using the device, one can quickly correct the faults attributable to the determination of a course through the use of a magnetic compass. Such faults are declension, deviation as well as possibly even drift. According to the invention the navigation device includes a frame plate (1), and a deviation disc (2) which may be turned and stored on the frame plate (1) at a bearing pivot. The deviation disc (2) is equipped with a compass scale (4) which with the help of the deviation disc turning in relation to the frame plate (1) can determine the degree, and with a bearing point (A) surround the closed deviation curve (6). The frame plate (1) or a plate connected to this is on a corresponding manner, equipped with a reading line (7) for deviation. Further belonging to the navigation device and at a distance from the bearing point (A) there is a declination scale (5), which can be indicated by using this as well as the necessary pivot point (D)of the navigation device. The compass course can be read on the deviation plate's (2) compass scale (4) the reading point location (E) is obtained by one through the storage point (A) proceeding normally (8) to one through the deviation point (C) and the pivot point (D) walking line (21). In practice this line is attained (21) and is the norm (8) i.e. through the use of the coordinate system which the longitude and latitude on a map form.<IMAGE>
