| - 3 - (2) Details. (a) Top tank to be deeper, narrower and rectangular in plan view. (b) Bottom tank to be a pressing with steel pieces to take the holding down studs spot welded into the pressing (this is standard practice on a number of radiators) (c) Inlet and outlet pipes to be cast and fixed into the top and bottom tanks as shown on Rm{William Robotham - Chief Engineer}327. Inlet pipe to be combined with filler and Rotherham filler as per sample which we will supply to be sweated into casting outlet pipe to have Rotherham drain cock (as per sample) screwed into it. (See Rm{William Robotham - Chief Engineer}327). (d) Baffle to be fitted in top tank above inlet pipe extending width of tank, Camel valve as per Rm{William Robotham - Chief Engineer} 327 to be fitted, or alternatively simple spring loaded ball valve - this to be dispensed with later if practicable. (e) Calorstat to be moved to front of top tank as per Rm{William Robotham - Chief Engineer} 327 and tunnel tube dispensed with. (f) Shutters to be mounted off shell at top and yoke at bottom, the support bracket being bolted to the shell at the base. (g) Matrix to be reduced in height and width and starting handle tunnel and cut away in side plates to be dispensed with. (h) Lamps to be supported off stiffened shell side plates, but shell not to be connected to wing stays. Rm{William Robotham - Chief Engineer}/Std.
