Abstract: A foldable pram chassis in which two lateral X-shaped frames are connected articularly with two horizontal carriage body and seat fixing struts, a U-shaped plate articulated to the lateral X-shaped frames and a rectangular slide frame, cross-struts of which are foldable so that the chassis may be collpased, the rectangular slide frame pivots in the U-shaped plate and lying over the carriage body and seat fixing struts.

Abstract: A track rail anchorage comprises a base member having projection flanges projecting from the two ends thereof, either of which may be placed so as to locate over the flange of a rail to be located in position. The base is provided with asymmetrical mounting means so that when one projection flange in location with the rail flange is exchanged for the other, the position of the new projection flange relative to the rail will be displaced towards or away from the rail, thus catering for possible displacements of parts of the rail due to distortion defects. Additional adjustment of the anchorage position may be achieved by employing a variable, eccentric, mounting in the base to receive a mounting bolt fixed in the ground.
