Abstract

1484257 Record-making press DECCA Ltd 7 Nov 1974 [22 Nov 1973] 54212/73 Heading B5A A record-making press has a narrow hydraulic pressure chamber 4 to which hot and cold liquid is alternately fed to force a flexible thermally conductive diaphragm 1 and a matrix 2 outwardly whereby the matrix contours are impressed on a sheet of thermoplastics material located between the matrix and a cushion 3. Passages 18, 19 are provided for the hot and cold liquid respectively which flows through an aperture 16, an annular sintered bronze collar 11, an annular chamber 10 containing a turbulence producing structure 21 and an annular chamber 4 housing a turbulence producing structure 20. Such structures may comprise a mesh, and are located on opposite sides of a plate 6 flexibly connected to a flange 7 by a rubber ring 6a. A low thermal capacity cellular structure 17 with walls 17a is positioned on one side of a portion 15 of a plate 12.
