Abstract: Abstract Device for controlling the spacing of the plates on a bridging arrangement for expansion joints in bridges or the like An device for controlling the spacing of the plates on a bridging arrangement for expansion joints in bridges or the like, in which device one or more plates run parallel between edge beams defining the expansion joint and are mounted on cross-members bridging the expansion joint.  The plate is coupled to the two edge beams, or each plate is coupled to an edge beam and an adjacent plate or to two adjacent plates, by means of resilient members arranged to act in shear.  Each resilient member is secured by one end to an edge beam or a plate and by the other end to a connector that is resistant to bending.  Each connector connects the resilient members of an edge beam and a plate or of two plates to one another.  All the plates are connected to one another and to the edge beams by one or more continuous control chains comprising shear springs and connectors.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention is a method of color electro-photography in which toner images are superposed sequentially on a photosensitive material sheet to form a multi-color image by using a liquid developer.          According to this method, the photosensitive material sheet is made to pass by a conductive doctor member and then by an air blasting member in sequence immediately after development, so as to form the multi-color image.          By this method, the multi-color image can be formed in the condition that most of a excess developer is removed while a small quantity of carrier liquid containing no residual toner particles is made to exist as a uniform liquid layer on the surface of the photosensitive material sheet, and thus a clear image free from a fogging of the surface can be obtained.

Abstract: RAILWAY WHEEL DETECTOR                         Abstract A railway wheel detector which is mechanically actuated by the flange of a railway wheel which engages a contacting surface of the detector which may be provided by a rigid plate.  This surface is supported by blocks of compressible, resilient material, preferably a closed cell foam elastomeric material, which has more stiffness in a vertical direction than in a lateral direction (the direction along the railway track) so as to transmit forces for actuating the plunger of an electrical switch mechanism when the flange of the railway wheel contacts the contacting surface, but allows the contacting surface to move with the wheel to avoid wear, thereby providing reliable operation over a long life time.  The switch is preferably hermetically sealed and the blocks of compressible, resilient material are preferably covered by a boot having bellows walls so as to enable the wheel detector to be installed outdoors on the rail of a railway track and to withstand severe environmental conditions.  A pair of such switches, together with blocks of compressible, resilient material which support contacting surfaces in close proximity to each other and laterally spaced along the railway track, is assembled in an integral unit so as to detect not only the presence but also the travel direction of the railway wheels and the axles which connect them.
