Filed: 1926-12-28
Abstract: 293,327. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Dec. 28, 1926. Vacuum tubes.-In gas-discharge rectifiers for single or multi-phase alternating current and comprising an oxide or other incandescent cathode and two or more anodes, back ignitions are prevented by one or more conductive screens between the cathode and an anode or between the anodes, the screens being arranged and shaped so that positive ions produced by the electron flow cannot reach one or more anodes. The filling is of rare gases purified by introducting magnesium &c. into the bulb, the pressure being from 1 decimeter to less than 1 mm. and being such that the distance of the screens from the anode is large relatively to the mean free electron path. The screens may be insulated or provided with a lead for the application of potentials. Small potential differences between the screens and the anodes may be produced by choosing suitable materials, e.g. molybdenum anodes are negative with respect to aluminium screens. A screen between two anodes may be arranged beneath the incandescent cathode and connected to one cathode lead. In a modification, Fig. 2, the cathode 7 is between the anodes 3, 4 and screens 8, 9 are arranged as shown to surround the cathode and divide off the discharge spaces, leads 10, 11 to the screens being provided. In a further modification, Fig. 3, the anodes 12, 13 are surrounded by helical grids 14, 15 which are welded to rod-shaped supports 16, 17 and may be conductively connected either inside or outside the rectifier through a high resistance to the anodes so that the latter will be located in a. space substantially without any field. The incandescent cathode 18 is arranged between the helical grids, and the supporting wires for the anodes are surrounded by small glass tubes 19, 20 to prevent the discharge from extending over the supporting wires. According to the Provisional Specification, the invention may be applied to rectifiers having a single anode.

Title: Process for the recovery of polycarbonates from solutions thereof
IPC: C08G64/40
Filed: 1964-08-13
Abstract: Volatiles are removed from substantially anhydrous polycarbonate solutions by introducing the solutions into a conduit having a heated zone, propelling the solution components through the zone exclusively by an internally sustained pressure provided by the feed pressure and the pressure generated by volatilization of the solvent, allowing the volatilized material to escape from the zone via an open terminal position and recovering solvent-lean polycarbonate from the terminal position. The conduit may be of serpentine form or it may be constructed in a vertical manner whereby gravity assists in propelling the solution through the zone.  Examples describe the removal of all or only part of the solvent from a solution of bisphenol A polycarbonate in methylene chloride or the removal of most of the methylene chloride from a solution of bisphenol A polycarbonate in a mixture of methylene chloride and mono-chlorobenzene.
