Filed: 1941-08-26
Abstract: 553,257. Treating grain. DEHN, F. B. (Mining Process & Patent Co.). Aug. 26, 1941, No. 10878. [Class 58] [Also in Group II] In the cleaning and husking of cereal grain by steps including wetting the grain, applying heat thereto and removing the outer skins by attrition without damaging or removing the innermost skin and wetting the grain kernels, during the attrition step the grain is mechanically moved along through liquid and the removed skins and contaminant matter floating on or near the surface of the liquid are removed by overflow. In the apparatus shown in Fig. 1, adapted for continuous operation, grain is fed to a tank 4, in which it is heated with water to form a free flowing mass which passes to an adjustable inclined mill 5. A frothing agent may be added in the tank. Alternatively, the grain may be heated in the tank and mixed with water in the mill. The grain is moved along the mill by spiral flights 5b to a discharge outlet at the upper end above the water level, the floating skins &c. being removed through an overflow at the lower end. From the mill 5 the grain passes, if necessary with additional water, through one or more flotation cells 6, thence over a screen 7 to a dryer 8, preferably of the rotary kiln type, for removing chaff and surface moisture. Heated air or other gas, supplied by a pipe 8a is removed by a blower 9 to a cyclone 10 for removing chaff &c. and may be supplied to the heating jacket of the tank 4. The mill 5 may be provided with a heating jacket 5a. In the modified mill shown in Fig. 2, the skins &c. and the grain are discharged through outlets 5d, 5e respectively, adjustable diaphragm openings being preferably provided at the feed inlet and the outlets.

Title: Improvements in adjustable liquid electric resistances
IPC: H01C10/02
Filed: 1924-05-05
Abstract: 227,339. Haighton, C. A. A. May 5, 1924. Liquid resistances.-An adjustable liquid resistance comprises a tiltable reservoir provided with electrodes and containing a resistance liquid and a non-electrolytic body so arranged that it is capable of movement with respect to the reservoir when the latter is tilted. In the form shown in Fig. 3 the reservoir a is made of insulating material such as glass and the non-electrolytic body d is mercury. On rotating the resistance of the liquid between the electrodes b, c, which may be platinum wires, is graduallv reduced until the electrodes are short-circuited. In one modification the elongated portion of the reservoir is straight and in another the electrode c is placed in a pocket on the same side of the axis of the reservoir as the enlargement d<1> so that the electrodes can never be short-circuited. The reservoir may also be cylindrical or spherical in shape as shown in Fig. 5 in which the non-electrolytic body takes the form of a metal conductor d pivoted at g and weighted so that it remains stationary when the reservoir is tilted. This may be effected by a float fixed above the conductor or by attaching a small case i containing mercury h as shown in the Figure. The resistance liquid may be distilled water completely filling the reservoir excepting a small bubble f of air which, if desired, can be before the tube is sealed. In a modification, one of the electrodes may be dispensed with, the second lead being taken directly to the conductor d. The weighted metallic conductor may also be pivoted at some distance from the centre of the reservoir. In this case the latter is provided with a conducting lining which acts as an electrode. Another form of reservoir shown in Figs. 8 and 9 has an enlargement d midway between the electrodes and is capable of rotation about an axis g substantially parallel with its own. On rotation, the mercury leaves the enlargement d and reduces the resistance between the electrodes. In the modification shown in Fig. 10, the reservoir is in the form of a curved tuba pivoted at g and containing a conducting body d which is preferably round and smooth and is connected to one of the electrodes by means of a flexible wire and remains vertically below the pivot g when the reservoir is tilted.

Title: Process for the manufacture of articles in silica glass
IPC: C03B5/02
Filed: 1924-05-05
Abstract: 224,164. Quartz et Silice. Nov. 2, 1923, [Convention clate]. Forming silica - glass articles.-A process of manufacturing articles of fused silica, or of glass having a high silica content, consists in melting the silica in a crucible of refractorv and conducting material by the induction of high-frequency electric current, expelling the plastic silica from the crucible either by pressure or by drawing, and then shaping the mass by pressure or by other suitable mechanical treatment. The charge a of sand, rock crystal or other suitable material is placed in a crucible b, made of graphite, which is closed at its upper end by a tightly fitted cover c with an inlet tube d. The bottom of the crucible is closed by a removable plug e of graphite. The furnace comprises a tube f, of copper or aluminium, wound on a cylinder g of insulating material. Water is circulated through the tube, and the space around the crucible is packed with a heat-insulator h, such as lampblack. High-frequency electric currents, produced by known means such as a highfrequency alternator, spark or arc generator, or thermionic valves, is passed through the tube f, and the crucible is raised to a high temperature by induction. When the material is fused, the plug e is removed and the plastic silica is expelled by means of gas under pressure admitted through the tube d. If the silica is to be made into rod, the plug e is replaced by a graphite draw-plate, and the silica. is extruded by the gas pressure, an external drawing device being also used if necessary. In making tubing, a tube is used to form a core for the extrusion aperture and for permitting the introduction of blowing air into the interior of the silica mass. The melting can be carried out in vacuo or in an atmosphere of a suitable gas introduced into the crucible through the tube d.
