As shown in Fig. 2, the press is mounted on wheels 5 and comprises an inflatable bag 6 upon which the sheets 1a, 1b are supported and an electrically heated upper platen 7. A rod 8, slidable in a fixed sleeve 9, carries the platen 7 and is hinged at 10 to a control lever 11 pivotable about a point 12. An abutment member comprising one or more blocks 15 is carried by a rod 14 slidable in sleeves 13, 13a so as to be insertable between the platen 7 and a frame component 16 when the platen is in its lowered position. In operation, the edges 3a, 3b of the sheets 1a, 1b are placed on the bag 6 and the platen 7 is lowered by the lever 11 into contact with the edge 3a. The block(s) 15 is/are inserted between the platen 7 and the component 16 and electrical contacts are closed to energize a solenoid so that compressed air passes into the bag 6 and, if the pressure of the compressed air corresponds to a setting given to a manometer, current is supplied to the platen 7 to heat seal the sheets. The platen 7 is heated for a predetermined length of time and its temperature is thermostatically controlled. If the maximum permissible temperature set on the thermostat is exceeded, the current supply to the platen is interrupted and a visual warning device and/or an audible warning device are/is energized. After the platen has been heated for the predetermined period, it is cooled until the temperature reaches a desired value further visible and/or warning device(s) are/is energized and the block(s) 15 is/are removed and the platen 7 is raised. After each heat application period, the sheets are cooled by a jet of cold air directed on to the platen before release of the sheets. The press is moved to the next portion of the edges and the cycle is repeated. An electrical circuit for the operation of the press is described, Fig. 4 (not shown).

Abstract: 1350703 Recovery of Hg and/or Ag values from effluents E B BURDON ENGS Ltd 30 June 1971 [6 May 1971] 30723/71 Headings C1A and C1C [Also in Division C7] Hg and/or Ag values are recovered from an aqueous industrial effluent by treating the effluent with a reducing agent capable of converting the metal value from the ionic or complex ionic form in which it is present in the effluent to an insoluble form and adding an organic flocculating agent, so that the insoluble form of the metal is precipitated with the organic flocculating agent, the precipitate being then separated from the attendant mother liquor. Inorganic nucleating agents may be added, e.g. ferrous or aluminium sulphates or calcium or barium salts, to aid precipitation. The reducing agent may be Na 2 S 2 O 4  or hydrazine. Silver in a photographic effluent containing AgNO 3  is first treated with Na 2 S 2 O 4  and Fe 2 (SO 4 ) 3  containing HCl and then with NaOH to a pH of 8À5 and a flocculating agent added. Mercury effluent may be treated in two stages (i) firstly by adding NaOH to bring the pH to 10-11, then adding HCl to a pH of 4-5 and finally adding a polyacrylamide flocculating agent whereby the Hg 2 Cl 2  is precipitated, (ii) by adding to the resulting filtrate first Na 2 S 2 O 4  then Al 2 (SO 4 ) 3  and polyacrylamide and finally adjusting the pH to 3-5 before separating the precipitate by filtration.
