Abstract: A concrete rail tie has an elongated tie body made of a first concrete material. The elongated tie body has an elongated top surface having a shaped profile. A preformed rail seat crown made of a second concrete material is embedded in the elongated tie body and disposed at a rail seat location of the elongated tie body. The preformed rail seat crown has top side flush with and shaped to match the shaped profile of the elongated top surface of the elongated tie body. And the second concrete material has a greater compressive strength and a greater flexural strength than the first concrete material.

Abstract: A method and system for creating metal beams utilizes laser welding to fusion weld top and bottom flanges to a metal web in a continuous fashion wherein the flanges and web are fed from coils. The system and method allow custom I-beams or T-beams to be more easily manufactured, as well as allowing the beams to be more economically manufactured with a smaller factory footprint and with a reduced amount of equipment. The system may include a coil feed subsystem, a conveyor, a first laser welder, and a second laser welder. The first and second laser welders weld the metal flange to the metal web along first and second sides, respectively, of the junction of the flange and web as these materials move. The first and second laser welders may be positioned longitudinally along the conveyor such that they simultaneously weld a common longitudinal position along the junction.

Abstract: A rail track insert assembly for use in road-level railway crossings having a pair of rails secured to a rail bed, each of the rails having a gauge side and a field side, a rail base and an intermediate web and being adapted for limited vertical movement upon intermittent loading of the rail upon passage of a load on the rail, the assembly comprising a longitudinally extending flexible gauge side rail insert member having a top surface in the plane of the rail head and a bottom surface registering with the base of the rail, a rail-engaging side surface sealingly and fixedly registering with the web on the gauge side in order to move with the limited movement of the rail, and an opposite side surface including a planar surface inclined downwardly and outwardly away from the adjacent rail at a minor angle, a longitudinally extending center gauge panel comprising a rigid slab having a top planar road surface lying in the general plane of the top surfaces of the rails, a bottom surface engaging with the tie bed,

Abstract: Rail track insert assembly for use between rails and adjacent road surfaces in a road level rail bed comprising resiliently flexible elongate members engaging, respectively, with the rail and the adjacent road surface and defining a generally vertical slip plane at their interface, to accommodate vertical movement of the rail in response to the passage of rail car wheels, while sealing against intrusion of surface water and detritus. An elongated channel defined in the under surface of each of the insert members accommodates rail clips securing the rail to the underlying track bed.

Abstract: In order to render harmless the aerosol laden smoke stream which results from the operation of medical lasers in or on mammalian bodies, the stream is moved in a closed circuit maintained at negative pressure. The circuit includes a container of sterilizing fluid to retain and destroy the larger aerosol particles and downstream of that container a chamber having an oxygen enriched atmosphere which is heated to a temperature sufficient to incinerate the remaining aerosol particles which are too small to filter. The thus purified stream is then cooled and released to ambient.

Abstract: An insert for use in a level railway crossing includes an elongated high molecular weight body defined by a generally trapezoidal head with one planar vertical side edge, a shoulder extending outwardly and downwardly from the other side edge of the head for bearing against the bottom of one side of the head of a rail, a bottom portion for extending downwardly into engagement with the top surface of the base of the rail at the junction between such top surface and the vertical web of the rail, and circular cross section seals in longitudinally extending rectangular grooves in the one side edge of the head and in the inclined top surface of the shoulder for sealing with an adjacent plank and with the rail. The insert restricts the entry of the water and other foreign matter into the area of the bottom of the rails.

Abstract: The puzzle has a single plane base on which are mounted movable puzzle pieces. The pieces are restrained in a fixed series of grooves and can be arranged in a desired pattern. The pieces are scrambled in a random arrangement to be then moved back to the desired pattern.

Abstract: The invention concerns assays, such a immunoassays or two-site immunometric assays, performed using a labelled reagent and another reagent bound to magnetically attractable particles which are suspendable but insoluble in a liquid assay medium. After the labelled reagent has become partitioned between the liquid phase and the particles, in proportions which depend on the concentration of an analyte in a sample, the liquid phase is removed. Then the particles are re-suspended in another liquid medium, and the concentration of label observed. The method is particularly suitable for fluorescent and chemiluminescent' label systems, and can conveniently be performed in microtiter plates in which the wells are optically screened from one another, the observations being made from above or below the wells.

Abstract: A method of performing an assay for an analyte comprises providing a chromatographic medium, preferably in sheet form, forming a reaction mixture containing a labelled reagent present partly in a form which is mobile on the medium and partly in a form which is immobile, the proportions of the two forms being related to the analyte concentration, applying the mixture to a spot on the chromatographic medium, optionally applying a solvent to cause the mobile form of the labelled reagent to migrate from the spot, and measuring the label intensity remaining at the spot. The method provides a convenient way of performing immunoassays, 2-site immunometric assays, and agglutination assays.
