Title: method of tracking current dislocation of running wheels of rolling stock in rail transport
Inventor: YERMAKOV OLEKSANDR MYKOLAIOVYCH
IPC: B61L25/00
Filed: 2006-05-26
Abstract: The invention relates to the devices of identification of the rolling stock in rail transport. A method of tracking current dislocation of running wheels of rolling stock in rail transport provides for use of an oriented one-line sequence of identifiers of available controlled running wheels on the elements of range and identifier of available controlled running wheel by sensors of range. The range is divided into the elements in such a way that the presence and one-line sequence of positioning the controlled running wheels on each element change only by their entry to this element from the elements adjacent to it. On each inter-element boundary a sensor is installed in such a way that in the area of its action there only one controlled running wheel can be. An interrogator of sensors at any moment determines one of following set of states of its operating zone: “there is no running wheel” in the absence of running wheel in the zone of action of this sensor, “there is a running wheel in one known part from two parts of sensor action zone located in known sequence along the rail” at presence of running wheel in the zone of action of the sensor. In the case of increase of the time of fixation of entries of controlled running wheels into the zones of action of sensors and withdrawals of controlled running wheels from the zones of action of sensors respectively the one-line sequences of identifiers of controlled running wheels of equivalent components of range and information about location of controlled running wheels in the zones of action of corresponding sensors of range are changed. Technical result: possibility of identification of the rolling stock at unforeseen change of quantity and sequence of railroad cars in the train or at movement of the train in the opposite direction without use of a reading device of carriage markers.

Title: Cyclone separator
Inventor: HANSEN MORTEN KAARE
IPC: B04C5/181
Filed: 2006-12-28
Abstract: Described is a cyclone separator comprising a cyclone housing (1), a discharge duct (5) and a central tube (3) for diverting gases, said central tube (3) extends axially into the cyclone housing (1) and being composed by a number of segments (3a) which are suspended on a supporting element (15) provided in the area between the cyclone housing (1) and the discharge duct (5). The cyclone separator is peculiar in that it comprises a number of carrying means (17) which are evenly distributed and fixed to the inner side of the cyclone housing (1) and/or the discharge duct (5), and in that the supporting element (15) comprises an annular disc which is loosely fitted on top of the carrying means (17) and having an outer diameter which is smaller than the inner diameter of the cyclone housing (1) and/or the discharge duct (5) so that a clearance (18) is provided between the annular disc (15) and the cyclone housing (1) and/or the discharge duct (5). Hereby is obtained a significant reduction in the heat transmission from the supporting element to the cyclone housing and/or the discharge duct so that the radial temperature gradient in the supporting element is reduced with an approximately uniform temperature over the radial cross section of the element. Hence the thermal stresses in the supporting element will be substantially reduced. This is mainly ascribable to the reduction in the contact area between the supporting element and the cyclone housing and/or the discharge duct.
