Title: Methods and apparatus for testing hollow articles
IPC: G01M3/32
Filed: 1928-11-24
Abstract: 301,422. Dague, B. S. Nov. 29, 1927, [Convention date]. Testing strength of hollow-ware and the like by fluid pressure.-Hollow articles are tested for weaknesses and flaws by partly filling the vessel with liquid and causing a fluid under pressure to impinge on the liquid so as to cause a sudden shock to the interior walls of the article. The invention is described as applied to the testing of condenser tubes in situ. At each end of the tube 2 closure members are inserted. The closure to admit air comprises a nozzle 17 screwed into the bore 10 of a block 9, from which bore passages 13, 11 lead to cocks 18, 15. A similar fitting comprising a block 23 with nozzle 24 and a cock 25 serves to admit liquid, a predetermined quantity of which is placed in a tube 26 secured above the cock 25. In use the nozzles of the closure members are inserted into the ends of the condenser tube and the fittings tapped home with a hammer. Water or other liquid is placed in the tube 26 and the cock 25 opened. The valve 26 is then closed and the valve 15 opened and closed quickly, admitting air from the reservoir 6 of an air-compressor. The water hammer produced causes very high momentary pressures inside the tube.

Abstract: 605,387. Variable-pitch propellers. GENERAL MOTORS CORPORATION. Dec. 21, 1945, No. 34663. Convention date, Jan. 15. [Class 114] In a variable-pitch propeller construction two sheet metal ring members 72, 74, Fig. 1, form a rotating sealed reservoir 54 which, together with a pump 56 and a control valve assembly 58, comprises a regulator 40 secured on to the hub 16 and controlling pressure to the torque units 26 in the blades 20. In operation the pump 56, Fig. 12, delivers fluid to the governor valve 178 via the valve 58 controlling pressure in the line 176. The governor valve allows fluid to pass either to decrease pitch line 102 or to increase pitch line 106, through respective filters 182 and 184. There is a feed-back connection from the increase pitch port 242 to the control valve 58 which maintains pressure sufficient for increased demand. To select the speed at which the governor mechanism effects constant speed control of the propeller, the pilot moves the fulcrum roller 262 along the lever 258 to change the ratio of centrifugal force to spring force acting on the governor valve 178. The pressure-regulating valve, the governor valve and the fluid filter units are all hydraulically connected to fluid circuit ports, and detailed constructions of each unit and its connections are given in the Specification.

Title: Process for the manufacture of pure carbon in a very finely divided state
IPC: C01B31/00
Filed: 1932-09-26
Abstract: Carbon in a very finely divided condition is obtained from carbonaceous material which is soluble or peptizable in an alkaline medium by carbonizing it in this medium in a neutral or reducing atmosphere.  In an example, a material rich in humic substances, such as brown coal, is ground, sieved and mixed with water, to which is added sufficient caustic soda to dissolve the humus completely, mineral matter being allowed to settle out or being removed by centrifuging.  The humic matter in then precipitated by the addition of acids or calcium salts, but preferably by the addition of gelatinous alumina, the precipitated mass being separated.  A mixture of sodium carbonate and caustic soda is added and the mass dried and powdered, after which it is heated in a neutral or reducing gas, such as illuminating gas, at 500-700 DEG  C.  Sufficient water is added to dissolve the sodium carbonate formed, the carbon is separated, washed first with water and then with dilute hydrochloric acid, dried and ground.  The solution of sodium carbonate contains the alumina, which can be separated for re-use by a current of carbon dioxide. Specification 342,653 is referred to.
