Patent DE-4313835-C1 (DE)
Title: Building-vibration damper for basic and higher frequencies
Inventor: HIRSCH GERHARD
IPC: E04H12/28
Filed: 1993-04-29
Granted: 1994-07-21
Abstract: The main weight oscillates on the building (1), and a lighter one (5) is suspended from it. Second coil springs of wire rope (6.2) are mounted between the two weights. The double pendulum mechanism is so tuned that at the basic frequency of the building the weights oscillate in phase, while at the higher frequency they vibrate in anti-phase.Third wire-rope coil springs can be mounted between the lighter weight and the building. Both weights are rings and the lighter one is axially and radially set inside to heavier one.
Patent DE-4423763-C1 (DE)
Inventor: RECK THOMAS DR ING
IPC: G01R19/02
Filed: 1994-06-28
Granted: 1996-02-01
Abstract: A digital process is disclosed for determining the effective value of a periodic electric measurement signal. The measurement signal is scanned during a scanning interval whose duration differs from the periodic duration of the measurement signal, and the scanned values are digitised squared, summed up and averaged. The root of the thus obtained mean value is then extracted. In order to calculate the effective value as quickly as possible and with high accuracy, N scanning values that correspond to a period of the measurement signal (U) are squared and summed, up to and including the (N-1)th scanning value. The N scanning values are obtained by M odd scans during a scanning interval that corresponds to two periods of the electric measurement signal (U). A correction value (KG) is added thereto that corresponds to the square of a subsum formed by one quarter of the (N-1)th scanning value and by three quarters of the Nth scanning value, in which N = (M-1)/2. An average is finally calculated of N+1 scanning values.

Granted: 1995-09-27
Abstract: FIELD: engine engineering. SUBSTANCE: engine has stator 1 with side covers 2 and 3, combustion chambers, cylindric space, and rotor 7 mounted coaxially. Separating plates 5 are received in grooves 4 made in the stator for permitting reciprocation. The rotor is in contact with separating plates 5 and side covers 2 and 3 and provided with alternating gas distributing and two working projections. The tops of the projections has the same radii drawing from the geometric center of rotor 7. Separating plates 5 define working chambers. The angle step of the projections is equal to twice angle step of separating plates 5. The volumes of gas distributing projections and working projections of rotor 7 are significant with respect to the volume of each working chamber. Each projection of rotor 7 almost fully displaces the gas from each working chamber without the contact between the tops of the projections and cylindric surface of the space of stator 1. Inlet and outlet ports are arranged on both sides of the tops of each gas distributing projection. Each cross-piece between the ports coinciding with the tops are confined by the angle which is equal to the central angle between separating plates 5. The working chambers are pressure-tight independently of the magnitude of the space between the tops of the projections of rotor 7 and cylindric surface of the space of stator 1. The cam mechanism (cams 20, rollers 19, and plungers 18) for driving separating plates 5 and bearings of shaft 6 are arranged in two oil baths 32 interconnected through spaces 34 provided in separating plates 5. EFFECT: improved design. 2 cl, 8 dwg

Abstract: FIELD: plastic material molding. SUBSTANCE: method of injection molding with use of a molding machine, having mold, comprises steps of plasticization and batching of the material, step of injection and step of pressure holding the material. After the injection step over a time period of performing the step of the pressure holding of the material a duct, having increased volume and passing from the molding machine housing up to a molding hole of a refining cavity of the mold, is being closed in its intermediate portion for interrupting its connection with an inner cavity of the machine housing. The step of the pressure holding of the material is being performed with use of at least a valve for subjecting to an inner pressure, a front part of the injected material, had been separated due to the closing of the molding duct and compacted in a constant-volume closed space, restricted by the valve and including the refining cavity of the mold. At performing this step the next step of plasticization ad batching is being begun. Before the end of the step of the inner pressure holding, upon each molding cycle a quantity of the material in the constant- volume closed space is being controlled by discharging an excess part of the material from a system, including the molding machine.

Abstract: FIELD: cryogenic engineering. SUBSTANCE: water vapor is separated from mixture to be pumped by their condensation on the condensing surface. Flow of the mixture is controlled upstream of the adsorption zone to provide full condensation of component to be condensed. The adsorption zone are tightly separated from the condensation zone before regeneration of the cryogenic pump. The zones are interconnected after the secondary cooling of the cryogenic pump. Temperature of non- condensed component of the mixture to be pumped upstream of entering the adsorption zone is used for controlling flow of the mixture. The tank for coolant and cooled chamber filled with adsorbent are positioned inside the housing provided with vacuum duct. A part of the vacuum duct is constructed as labyrinth passage and received in the tank for coolant. A movable valving-controlling member of the valve is mounted at the outlet of the chamber inside the space of the vacuum duct. One of the ends of the pipe line is arranged in the zone of the vacuum duct bottom. The other end of the pipe line is brought out of the housing through the valve.

Abstract: Изобретение относится к гидротехнике, а именно к водозаборным сооружениям. Поток воды, поступающий в подводящий канал 1, начинает взаимодействовать с системой наносозадерживающих элементов, выполненных из последовательно установленных в нем пластин 4, совместно устновленных с пластинами 8 и 9, объединенных в независимые элементы. За счет крепления пластин 4, 8 и 9 к горизонтальным осям 6, установленным в подшипниках, они под воздействием набегающего потока отклоняются и тем самым устанавливаются в рабочее положение. Стабилизаторами их положения являются противовесы, прикрепленные рычагами со стороны отводящего канала 2 к горизонтальным осям 6. За счет наличия трех групп пластин 4, 8 и 9, имеющих различную длину, поток в поверхностных и средних горизонтах начинает активно тормозиться, при этом существенно переформируется вертикальная эпюра скоростей таким образом, что максимальные скорости присутствуют в придонном слое потока. Поток, обтекая пластны 4, 8 и 9, проходит сквозь вертикальные прорези, где теряет свою скорость, в результате чего происходит осаждение взвешенных наносов из верхних слоев водотока в донный горизонт. Повышению интенсивности этого процесса способствуют различная компоновка и геометрические размеры пластин 4, 8 и 9. Наносы транспортируются в придонном слое водотока и затем посредством наносонаправляющего донного порога 7 отводятся в сбросной канал. 6 з.п. ф-лы, 4 ил.
