Title: Apparatus for, and method of, converting thermal energy directly to electrical energy
IPC: H02K44/08
Filed: 1964-04-14
Abstract: 1,031,943. Generators operating by electromagnetic interaction with fluids. NORTH AMERICAN AVIATION Inc. April 14, 1964 [April 17, 1963], No. 15432/64. Heading H2A. Thermal energy is converted into electrical energy by forming a vaporized fluid which is passed through means to increase its kinetic energy to form a driving stream and mixing with this driving stream a liquid to condense the vapour and provide a working fluid, comprising mainly liquid, which is passed into a magnetohydrodynamic generator to convert at least part of its kinetic energy into electrical energy. As shown, a liquid metal, preferably liquid sodium at 1215‹ F., is heated in heat source 22 by known means to produce a vapour at 1975‹ F. which is then expanded in nozzle 26 to produce a high velocity stream of vapour. A supply of liquid metal at 1215‹ F. is injected at the nozzle constriction 30, through regulator 29, and mixes with the vapour stream to provide at outlet 31 a high velocity (350 ft./sec.) liquid/vapour stream at a temperature of 1640‹ F. and vapour content less than 30% of the total volume. The working fluid exhausted from the generator is passed through a heat sink where the remaining vapour condenses so that liquid metal is pumped along pipes 37 to be recycled. The injected liquid may be atomized by mixing vapour through line 25 with the liquid in line 28 before injection into the nozzle. In a modification. Fig. 1A (not shown), the liquid in line 20 may be used as the coolant in the heat sink and is thus preheated. Examples of materials used comprise Li, Na, K, Rb and Hg, and the vapour may be superheated, saturated or wet. The characteristic curves of velocity, pressure, enthalpy and the like are given. It is also contemplated to employ additional condensing means between the nozzle output and the generator input.

Abstract: 351,679. Testing wearing qualities of cloth &c. DEELEY, R. M., 43, The Grove, Isleworth, Middlesex. May 21, 1930, No. 15619. [Class 106 (ii).] Comprises a method of testing the wearing qualities of materials such as cloth which consists in passing the surface of the material against another surface and observing the change in the friction between the two surfaces due to wear. Portions of the cloth to be tested are carried on lower and upper carriers 1, 2 each comprising a horizontal disc on one surface of which projections 1a are formed constituting virtually an interrupted annular ridge. A piece of cloth c is stretched over each projection and secured by a coned clamping ring 1b. The lower carrier 1 is rested on a horizontal dished holder from which a driving peg 3a projects into a hole in the carrier. The upper carrier 2 rests on the lower 1 with the cloth surfaces resting one on the other. A central projection 3b engages a central hole in the carrier 2 which has two posts 2c adapted to be loaded with slotted weights. Mounted in a fixed bearing 5 is a spindle 6 provided with a cross bar 6a the ends of which are in the paths of the posts 20 which rotate the spindles against the influence of a coiled spring 7. The upper end of the spindle has a helical groove engaging a pin on a recording pointer 9 to rock it about a fulcrum 9b across the surface of a clockdriven drum 10. The disc is rotated through bevel gear from a pulley 22 and the spindle 6 rotated through friction, the spring being wound up until the friction is balanced when the spindle 6 is stationary and the line on the drum remains at the same level. The length of time this level is maintained is a measure of the wear.

Title: Improvements relating to extruded catalysts
IPC: C10G45/34
Filed: 1960-05-04
Abstract: In a method of making extruded catalysts composed of catalytic material supported on a carrier, the dried extrudates are subjected to attrition to remove from 0,2 to less than 1% by weight of total catalyst, of the extrudate exterior.  The method is particularly described with reference to supported nickel catalysts on sepiolite, alumina, a clay mineral or Kieselguhr. The carrier may be impregnated with a solution of nickel formate, acetate or nitrate, which salts are subsequently converted to metallic nickel by decomposition and if necessary reduction with hydrogen.  Preferably this catalyst contains 1-50% of nickel.  The efficiency of the catalyst is demonstrated by hydrogenating gasoline fractions in the presence thereof.
