Abstract: Способ может быть использован для осушки и очистки сжатого газа в компрессорных установках. Газ сжимают в компрессоре. Проводят предварительную осушку и очистку газа в водомаслоотделителе с последующей осушкой его в одном из двух попеременно работающих адсорберов. Окончательную осушку осуществляют в концевом фильтре. При этом в процессе осушки газа в одном из адсорберов осуществляют регенерацию второго адсорбера. Переключение адсорберов с режима осушки на режим регенерации и обратно производят с использованием быстродействующих клапанов. При переключении адсорберов предварительно отключают насыщенный адсорбер от магистрали нагнетания газа, затем в течение 4-6 с производят сброс давления только из водомаслоотделителя, после чего сообщают прошедший регенерацию адсорбер с магистралью нагнетания. Насыщенный адсорбер подключают к магистрали регенерации с последующей его разгрузкой. Это сокращает время холостой работы компрессорной установки при переключении адсорберов, что повышает экономичность способа. 1 ил.

Title: Cellular signal enhancer
Inventor: MCNEILL DONALD JOSEPH
IPC: H04B7/155
Filed: 2003-02-26
Granted: 2010-03-04
Abstract: A low-cost user portable signal enhancer unit for extending service coverage of wireless communications to a user in a desired area of limited coverage. The enhancement supports an increase of signal power levels to allow wireless communication usage in a location, such as a small office or home office environment where the original cellular signals are weak or unreliable. A base station signal is enhanced by a bi-directional amplifier device (BDA), which receives a base station signal, amplifies the signal power and retransmits the amplified signal in a first signal path to a user in close proximity. The bi-directional amplifier also receives a user signal, amplifies the signal power and retransmits the amplified signal to the base station in a second separate signal path. Dual polarized antennas can receive and transmit the respective signals at opposite polarizations to increase isolation of the signals.

Title: Methods and apparatus for positioning measurements in multi-antenna transmission systems
Inventor: SIOMINA IANA
IPC: H04W64/00
Filed: 2011-03-10
Granted: 2015-06-11
Abstract: This document discloses solutions for using a mix of reference signal types in a wireless communications network, e.g., a first type and a second type, in making positioning-related measurements. In one example, a UE uses a "mix" of CRS and PRS. As an example case, a UE receives PRS and, possibly, CRS from one or more cells, while it receives only CRS from one or more other cells. In this case, the UE determines, e.g., received signal timing values for CRS as received from some cells, on a per-cell basis, and for PRS as received from other cells, on a per- cell basis. The UE can measure and report on per-signal/per-cell basis and can perform calculations involving a mix of timing measurements made for both CRS and PRS. In a further aspect, reference signal transmissions are controlled or coordinated on a per-port basis in cells that use multiple antenna ports for transmitting within each such cell.

Title: Method for cleaning wound stator stack of electrical machine
IPC: H02K15/02
Filed: 2000-12-15
Granted: 2001-07-27
Abstract: FIELD: electrical engineering and machine tool manufacture. SUBSTANCE: method used for cleaning outer surfaces of round cylindrical parts such as stators of electrical machines from impregnating materials involves removal of impregnating material laps and film from stator outer surface and from its inner surfaces by means of scratchy-finishing machine with revolving scratching brushes. Novelty is that prior to cleaning outer surface of stator stack its butt ends are covered with shielding caps; width of stack of brushes used for the purpose amounts to 0.1-0.35 of stator stack length; outer surface of stator stack is cleaned while the latter and stack of brushes are revolving unidirectionally with independent longitudinal displacement of brush stack along outer surface of stator stack, longitudinal displacement being started with delay relative to initiation of rotary motion of stator and brush stacks and stopped in advance of termination of rotary motion of stator and brush stacks for time Δt which is minimum 0.7V/B, where V is longitudinal displacement speed of brushes, m/min; B is width of brush stack, m; stator inner surfaces are cleaned before or after cleaning its outer surface. Proposed method provides for maximal difference in relative opposing displacement speed of stator stack surface section and that of working ends of brushes rubbing against it as well as for optimal choice of relative lengths of brush and stator stacks and treatment conditions. EFFECT: improved uniformity and quality of cleaning over entire stator surface, reduced brush wear and metal input. 5 cl, 6 dwg

Abstract: FIELD: instrumentation. SUBSTANCE: process of control over planeness of free surface of liquid near inclined plate is improved by way of use of thermal capillary convection induced by laser beam. While measuring edge angles of wetting portion of laser inducing convection and reflected from free surface of liquid is projected on screen positioned in cross-section of caustic of reflected beam. Corresponding interference picture is viewed on screen. Wetting of inclined plates used in measurement leads to static deformation of free surface of liquid between them having form of cylindrical meniscus. Form of response depends on value and sign of static curvature thanks to property of additivity of dynamic curvature of thermal capillary recess and static curvature of free surface of liquid. In case of unidimensional static curvature of free surface of liquid between plates thermal capillary response from laser beam incident between them has shape of ellipse. EFFECT: elimination of subjectivity factor and automation of high-precision measurements. 4 dwg
