Filed: 1971-04-19
Abstract: 1298643 Turbomachine blade shrouding GENERAL MOTORS CORP 19 April 1971 [6 May 1970] 22063/71 Heading FIT In a gas turbine engine the stationary shroud surrounding the tips of turbine rotor blades comprises a ring 23 supporting via flanges 43,44 a laminated porous sheet 34, the pores 75 of which communicate with a preponderant number of the cells of a honeycomb facing 32 secured to the sheet. The latter is formed from three slightly spaced layers 38,39,40 the pores 75 of which are out of alignment so that cooling air supplied to the chamber defined between layer 40 and a ring 42 follows a tortuous path in flowing through sheet 34 to honeycomb 32. The forward end of the chamber is defined by a laminated flange 64 also having cooling passages. Sheet 34 and associated ring 42 and honeycomb 32 are formed as 90 arcuate segments the adjacent ends of which are skewed at 36, Fig.7 (not shown). To prevent leakage of cooling air channel section blocks (76) Figs.8, 9 (not shown) are welded between layer 40 and ring 42 at the ends of each segment. Support ring 23 is made in two 180 halves and is itself supported by a mounting ring 20 bolted to the turbine casing. Circumferential movement of ring 23 is prevented by dowels 26 engaging slots 27 in the ring. The cooling air is supplied from the engine compressor via passages (56, 57, 59, 60) Figs. 1, 2, 5 (not shown) in the respective rings, baffles (63) being secured over the passages (60) in ring 42 to prevent direct impingement of the coolant on layer 40.

Title: Improvements in and relating to gaseous electric discharge devices
IPC: H01J17/06
Filed: 1930-07-22
Abstract: 362,346. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Foulke, T. E. ; 30, Evelyn Place, Nutley, New Jersey, U.S.A.) July 22, 1930, No. 22124. Convention date, July 27, 1929. [Class 39 (i).] Electrodes for gaseous dis. charge devices are made by coat. ing the electrodes with an alkaline compound, driving off occluded gases by heating in vacuo, decomposing the compound to form the alkaline oxide, and reducing the surface of the oxide to meta by a high voltage, gas discharge with the electrodes at a high temperature. To form a device operating at 80-100 volts D.C. or A.C., iron or nickel electrodes 4, 5 are cleaned and are heated in vacuo or hydrogen to facilitate subsequent removal of occluded gases. One or each electrode is coated with carbonate of potassium, caesium, barium, strontium, or of other alkali or alkalineearth metal by painting or spraying using a binder of alcohol or water or preferably a carbonaceous binder such as collodion. The electrodes are sealed in the glass or silica envelope 1 which is baked at 450‹ C. and exhausted. The electrodes are then heated to 1000‹ C. by high-frequency induction to remove occluded gases, carbonize the binder, and form alkaline oxide. Neon mixed with À5 per cent of argon is introduced at 5 mm. pressure and, with the electrodes again heated to 1000‹ C., a discharge is produced using a source of 300-500 volts D.C. or A.C. to reduce the surface of the oxide to metal. The gas is removed and the final atmosphere of neon, helium, argon, or mercury vapour or mixtures is introduced : a mixture of neon, or neon and helium, with À1-5 per cent of argon, at 15-25 mm. is specified. The electrodes are uniformly activated by a high-frequency discharge raising them to red heat and are aged by a smaller A.C. discharge. To confine the glow to the outer surfaces of the electrodes, they are coated only on their outer surfaces, or are spaced by a bead 6 at a distance less than the mean free path of the ions of the gas.

A dry electrolytic capacitor comprises an anode of a film-forming metal such as tantalum and a cathode of a non-film forming substance such as graphite, silver or silicon, the electrodes being separated by a solid sulphate which is maintained in close contact with both electrodes. Preferably tin sulphate is employed, though it is stated that bismuth and antimony sulphates may also be used. In the embodiment shown a tantalum disc 5 which may be anodized prior to assembly in sulphuric acid is separated from graphite discs 1, 2 by means of pressed tinsulphate discs 3, 4. To increase the capacitance the tantalum disc may be etched electrolytically in an acid fluoride salt. The assembly is held together by a rivet 6 which is insulated from the tantalum by a plastic sleeve 8. The rivet 6 supports a negative terminal 7 electrically connected to the graphite discs. A positive terminal 9 is provided by a solderable metal element pressed to a tab extending from the tantalum disc 5. The assembly may be sealed by dipping in a silicone varnish or by encasing in an epoxy-resin casting. In a modification the negative electrode may be in the form of a silicon cup which also serves as the cell container. A reversible capacitor may be constructed having two film-forming electrodes.
