Abstract: 1294330 Gas blast switches WESTING- HOUSE ELECTRIC CORP 3 Dec 1969 [30 Dec 1968] 59063/69 Heading H1N In a gas blast switch of the kind having a primary blast valve 88, 89 adjacent the contacts 77, 81 and moving therewith, and one or more secondary blast valves 49, (50) located downstream of the gas flow to cut off the flow after the contacts have separated, means is provided to latch the secondary valves in their open position. The primary blast valve is formed by the tip 88 of the movable contact 77 engaging a spring loaded seat 89. The movable contact 77 is coupled by a rod 75 and ladder assembly 74 to a piston and cylinder operating device as described in Specification 1,293,607. Also attached to the threaded rods 43 of ladder assembly 74 is a tripping member 79. A compression spring 105 between the secondary valve member 49 and member 79 urges the valve closed but, with the contact closed, it is held open by engagement with the stepped end of a pivoted latch 109. During an opening operation the assembly 74 with member 79 moves upwards compressing spring 105. When the contacts are fully opened parts 108, 109 engage to release the latch and the secondary valve is closed rapidly. During reclosure of the contacts the secondary valve remains closed; after the contacts engage, a rubber buffer 111 on member 79 pushes the valve open into the latched position. The space surrounding the contacts is filled with SF 6  at high pressure and this exhausts through the hollow contacts by way of valve 49, and a similar valve (50) associated with the fixed contact structure 83, into a low pressure chamber inside a hollow insulator which forms one arm of a U-shaped structure (Fig. 1, not shown) with a terminal in the other arm as described in Specification 1,293,369. In a modification (Fig. 9, not shown) the switch has two series connected contact sets with one secondary valve associated with each, the fixed contacts being blocked off.

Trimellitic anhydride is produced by distilling the reaction mass obtained by oxygen or air oxidation of pseudocumene in a carboxylic acid solvent using a heavy metal salt as catalyst, at a pressure of 200-800 mm. Hg abs. to remove the carboxylic acid solvent and dehydrate trimellitic acid to anhydride and rectifying the residue at a pressure below 20 mm. Hg abs. The oxidation step may be effected at 110-230‹ C. at 3-15 kg./cm.<SP>2</SP> in acetic acid using salts of Co, Mn and Ba. The distillation step may be carried out in the presence of a water-entraining  agent, e.g. benzene which may be added to the pseudocumene oxidation feed, and yields a distillate comprising carboxylic acid, water and water-entrainer, if used, which may be recycled directly to the oxidation step. The residue comprising principally trimellitic anhydride is rectified, preferably at 1-10 mm. Hg abs., to give a middle fraction of pure anhydride and leaving a residue from which the heavy metal catalyst can be recovered.
