Abstract: The track is divided into successive sections starting from a start point and for each of these sections and for each line of rails the wavelengths and/or amplitudes of the longitudinal undulations of the tread of the rail are measured and the transverse profile of the rail head is measured. A reference profile is then compared with the measured transverse profile and the transverse cross-section of metal to be removed in order to correct the transverse profile of the rail is determined, then the longitudinal cross-section of metal to be removed in order to correct the longitudinal profile of the rail is determined as a function of the amplitudes of the longitudinal undulations of the rail. The total cross-section of metal to be removed is determined and as a function of a working speed, of the metal removing characteristics of the tools and, as a function of this total cross-section of metal to be removed, the minimum number of tool passes necessary is determined.

Abstract: A method and apparatus for sorting articles with small density differences utilizing a flotation stream. A separator is provided in which a flotation stream continuously flows through a trough and is used to effect the separation of a mixture of articles having small density differences into several groups. Each density group of the mixture of articles to be separated is introduced at the head of the flotation stream at a selected depth. In one embodiment, the flotation stream may be comprised of a fluidized bed which is created by forcing a gas upwardly through a fluidization medium such as sand. In another embodiment of the invention, the flotation stream may be formed from a liquid. Once the mixture of articles is introduced at the selected depth into the flotation stream near the head of the stream, since the density of the flotation stream is greater than the density of the articles, the articles of lesser density begin to ascend toward the top of the flotation stream while at the same time the articles are carried downstream by virtue of the velocity of the flotation stream. Articles having a greater density will be carried further downstream whereas articles having less density will ascend to the top of the stream at a point further upstream, thereby effecting a spacial separation of the articles based on their differing densities.

Abstract: An electrolytic cell for the labeling of proteins, peptides and other organic molecules employs a cathodic half cell and an anodic half cell, where a porous working electrode is located in one half cell and a counter electrode is located in the other of the half cell, the two half cells being divided by a separator. A reference electrode located in the half cell containing the working electrode, and placed outside the current path between the working electrode and the counter electrode confers precise control of the working electrode potential, which allows the maximum rate of labeling to be achieved while minimizing oxidative damage to the protein, peptide or organic molecules. Saturation of the working electrode with non-radioactive label coupled with a ratio of working electrode surface area to volume of half cell containing the working electrode between 0.001 to 10 cm<-><1> minimizes the problem of loss of activity of radiolabel due to adsorption on the working electrode. <IMAGE>

Abstract: A data cache and method provides for the handling of errors during data copy-back from a data cache write buffer to external memory in a processing system including a processor. When data requested by the processor at an addressed storage location of the data cache is data which is valid, modified, and other than the data requested by the processor, the data is first transferred to the data cache write buffer and then written back to external memory after the requested data is fetched from a memory bus. If an error occurs during the write back of the data from the write buffer to external memory, the data is transferred from the write buffer to the storage location of the data cache originally addressed by the processor before the memory bus is released.
