Abstract: This invention relates to the field of electrical technology, and relates particularly to a method for the continuous transformation of electrical energy with its subsequent transmission from an initial source (transformer) to a consuming device, and also to an apparatus for the implementation of this method of transformation and the supplying of power to electrical devices through a transmission line which does not form a closed circuit, ie consists of a single conducting wire.      This invention therefore provides a method and associated apparatus for supplying power to an electrical device(s), including generation and subsequent transmission thereof to a receiving device via a transmission line, the method being characterised by the transformation of the electrical energy which is generated into the energy of oscillation of a field of free electrical charges such as the displacement current or longitudinal wave of an electrical field, the density of which charges varies in time, and the transmission of the energy via a transmission line which does not form a closed circuit comprising a single-wire transmission line and, where necessary, its transformation into the electromagnetic energy of conduction currents.

Abstract: A railway vehicle truck bolster friction shoe pocket includes a sloped rear wall and longintudinally spaced sidewalls depending from the rear wall to form a friction shoe pocket having open top and bottom ends for receiving a variable rate type of friction shoe. During rotation and translation of the bolster with respect to the truck sideframe, the outboard friction shoe pocket sidewall is repeatedly impacted by the outer and upper corner of the friction shoe. The impacting causes protuberances to form in the outboard sidewall, but only on the upper portion of the wall. The same sidewall is provided with a relieved section across the entire sidewall upper portion in order to eliminate the impact contact area between the upper portion of the friction shoe and the upper portion of the outboard sidewall. Eliminating the contact area eliminates the formation of protuberances and extends the life of the bolster.

Abstract: A method for on-line handwritten data verification based on the comparison of the dynamics of sample (31 or 32) and reference data (21 or 22) by implementation of correlation function analysis. Reference dynamic data concerning scriber (11) movement during data formation is recorded and converted to digital form (13). Prior to evaluation to-be-verified data, both the reference and to-be-verified data dynamic digital signals are pre-processed to eliminate time distortions. A "sliding window" mechanism is used to establish the mapping between phase coincident regions of the reference and of the to-be-verified signals.    Then multi-dimensional cross-correlation function analysis is applied to the pair of indivisible stationary signals. The resulting measures of similarity an then compared with thresholds that have beta selected to determine acceptance or rejection of the to-be-verified signals. The method and the apparatus can be applied to data authentication in a wide variety of applications like security for physical mess, for credit card authentication, electronic voting, and the like.

Abstract: A method and apparatus for assembling a spool valve into a valve bore of a body by providing compressed gas to the valve bore at a pressure below the pressure of compressed gas supplied to a passage within a carrier body containing a spool valve substantially concentrically aligned with the valve bore to advance the spool valve from the passage into the valve bore. The compressed gas in the passage provides a force acting generally uniformly on the spool valve substantially concentrically aligning the spool valve within the passage. The compressed gas supplied to the valve bore also acts substantially uniformly on the spool valve tending to substantially concentrically align the spool valve within the valve bore when the spool valve is advanced therein.  While the gas in the passage and the valve bore align the spool valve, the higher pressure of the gas in the passage advances the spool valve into the valve bore.
