The Solar Guard officer referred to the lead-lined jet sled that removed the reactant piles from all ships that were to be laid up for longer than three days. "And you'd better get over to your dorm right away," Strong continued. "You have to get ready for parade and full Corps dismissal." Tom grinned. "Yes, sir!"
The other substances employed provide further examples of this ease of production. Ethyl-dichlor-arsine was produced in homogeneously lead-lined vessels, identical with those used for diphosgene. Dichlor-methyl-ether presented difficulties which were solved by applying the German method of using tiled vessels.
The sailors of the "Belle Poule" protested that the catafalque was too frail, and the height too great. They dared not, they said, attempt to get the lead-lined coffin up to the place assigned for it, still less try to get it down again. It was consequently deposited, for fear of accident, on a low platform between the wheels.
He turned to the chart screen and began plotting rapidly. Down on the control deck, Strong was listening to Tom. " ... and Astro said we'd need the special equipment at the space shipyards to clean out the radiation, sir. If we took passengers aboard and it suddenly shot up well, we only have the three lead-lined suits to protect us." "Very well, Corbett," replied Strong.
The first step in any process for reclaiming rubber is the grinding of the waste, for which purpose several machines have been designed specially, an early patent for disintegrating rubber scrap by "subjecting it to the abrading action of grindstones" having failed to meet with favor. The most usual chemical treatment is a bath in a solution of sulphuric acid in lead-lined tanks.
It appeared that the practice in different factories had included the use of sulphuric acid varying from a 2½ per cent. solution to the full commercial strength of the acid, but one of the defendant companies based their case upon their use of acid of the strength of 28° to 30° Baumé, whereas the patent they were charged with infringing specified a strength of 66°. Their tanks were lead-lined and provided on the interior with steam pipes running down the sides and along the bottom, the sections at the bottom being perforated and the steam admitted at a pressure of 75 to 80 pounds.
