Filed: 1946-05-13
Abstract: 620,492. Gas turbine plant. GRIFFITH, A. A. May 13, 1946, No. 14414. [Class 110(iii)] Air is taken in by a supercharging compressor 7 passes through an interstage cooler 12 to a main compressor 1 and is delivered through a heat-exchanger 2 to a combustion chamber 3. The products of combustion are used in a high-pressure turbine 4 driving the main compressor 1 and a low-pressure turbine 5 providing useful power. The exhaust goes through the heat-exchanger 2 and is further expanded in an exhaust turbine 8 which drives the supercharging compressor. When the heat-exchanger 2 has a high efficiency, the power supplied to the turbine 8 is varied by by-passing the heat-exchanger and/or, burning further fuel in the chamber 9. When the heat-exchanger has a low-exchanger has a low-efficiency, the turbine 8 is brought to idling condition by a by-pass to atmosphere at 13. Specification 529,786 is referred to.

Title: Improvements in or relating to hydrogenation catalysts
IPC: C11C3/12
Filed: 1931-05-20
Abstract: The hydrogenation of unsaturated organic compounds in the liquid state is effected with catalysts consisting of a mixture of chromium oxide and copper oxide or a mixture of chromium oxide and zinc oxide prepared in a compact form by the oxidation of an alloy of the two metals.  The oxidation may be effected by anodic oxidation in an aqueous or other electrolyte or by the action of an oxidizing acid, such as nitric acid, followed by conversion to oxide.  The catalyst may be treated with hydrogen under conditions such that substantial or complete reduction of one but not more than one of the components takes place.  The hydrogenation is preferably effected in a continuous manner and the process may be applied to the hydrogenation of ethylenic, acetylenic or benzenoid linkages and to the hydrogenation of aldehydic or ketonic carbon-oxygen groups. According to examples, (1) an unsaturated oil of the glyceride type, e.g. cotton or whale oil, is hydrogenated at 150 DEG  C. and under a pressure of 200 atmospheres using a chromium oxide-copper oxide catalyst obtained by anodic oxidation of a copper-chromium alloy. (2) Benzene is hydrogenated under the conditions stated in the above example.  (3) Acetone is converted into iso-propyl alcohol at 150 DEG C. and under a pressure of 150 atmospheres using the catalyst specified above.

Title: Improved luminous electric discharge tubes
IPC: H01J61/09
Filed: 1926-06-18
Abstract: 277,739. Demoulin, J. June 18, 1926. Vacuum tubes.-Luminous electric discharge tubes filled with rare gas are provided at one or at each end with a plurality of substantially identical electrodes connected in parallel, each electrode comprising a spirally wound plate of metal of high melting point such as tungsten or molybdenum. At each end the discharge occurs at one electrode at a time and passes rapidly from one electrode to another; slight differences in the resistance of the electrodes due to lack of atomical homogeneousness of the metal cause the discharge to occur at the most conductive electrode first, the discharge then heating the electrode and increasing its resistance and passing to another electrode until the original electrode cools and again takes the discharge. Heating of the electrodes and absorption of the gas filling are thus minimized. At one or each end of the tube, electrodes 1, 2, Fig. 3, spirally wound to reduce their volume and to allow them to expand on heating without straining their glass supporting cups 4, are mounted in branches c. d of the luminous tube a and connected in parallel by leads 5. The electrodes are freed from occluded gases prior to mounting in the luminous tube by passing a discharge between them in a separate tube 7, Fig. 4, filled with nitrogen, the current being supplied and regulated by a transformer 8 and an adjustable inductance 9 with a movable core. Repeated fillings of nitrogen are introduced through a tube 10 and withdrawn through a tube 12 leading to a vacuum pump until spectrum analysis of the nitrogen shows that the electrodes no longer liberate gases. Potassium is placed at 11 to absorb gases such as ammonia and nitrogen peroxide formed by action between the nitrogen and gases liberated from the electrodes. After mounting the electrodes in the branches c, d and sealing these to the tube a, the tube is purified. by filling with nitrogen and producing a discharge. Oxygen and hydrogen are absorbed by an auxiliary electrode comprising a plate of palladium heated by the, current and mounted in a part subsequently sealed off from the tube. 'The tube is evacuated, nitrogen is eliminated by a glowing tungsten filament, and neon or helium, purified by a glowing tungsten filament in the supply pipe, are then introduced. The branches c, d may be cleaned in nitric acid before fusing to the tube a, traces of the acid subsequently decomposing to supply some nitrogen.
