Title: Improvement in art of refining edible oils, fats and analogous products
IPC: C11B3/00
Filed: 1936-06-22
Abstract: Fats, oils, and waxes are refined and stabilized by treatment with an organic peroxide in presence of a precipitant of mucilaginous matter at a temperature below that required to decompose the peroxide when heated alone, an excess of peroxide being used so that the purified oil contains a substantial amount thereof.  Blowing with superheated ization.  The peroxide is preferably a peroxide of one or more of the natural ingredients of the corresponding crude oil, e.g. of the acids in the "foots." The precipitant may be dilute sulphuric, nitric, or phosphoric acid, a neutral solid such as aluminium sulphate, an adsorbent such as fuller's earth, but when free fatty acid is also to be removed is preferably an alkali metal hydroxide or carbonate or a weak acid salt forming a soap insoluble in the oil; suitable precipitants are sodium hydroxide, carbonate, borate, and phosphate, maybe with added bicarbonate, boric acid, or phosphoric acid to reduce the pH value.  Specified substances treated are wax, lard, butter, tallow, and castor, linseed, palm, olive, cottonseed, coconut, corn, and soya bean oils.  In an example, 1000 lb. of corn oil is agitated for 1 hr. at 50--55 DEG  C. with 5--10 lb. of peroxides made from corn oil foots, and then for 1--2 hr. with a 16--40 DEG  B<\>ae. solution of 4,25 lb. of caustic soda; after settling, the foots and mucilaginous matter are removed by decanting or filtering.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J31/52
Filed: 1936-06-23
Abstract: 472,860. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. June 23, 1936, No. 17419. Convention date, July 6, 1935. [Class 39 (i)] In producing optical images from television signals, a charge-storing grid 16 with a surface of insulating material is uniformly flooded with electrons and also bombarded and scanned by an electron beam from a gun 2 to build up charges on the insulating surface corresponding to picture signals and so to control the electron flow through the grid to form a picture on an adjacent luminescent screen 21. The flooding electrons are emitted by two indirectly heated cathodes 26 surrounded by spiral grid, lowvoltage anodes 34 and arranged on opposite sides of the beam from the gun 2. The cathodes 26 are spaced by a cross-bar 31 supported on the envelope 1 at 32. The grid 16 is a fine-mesh nickel screen smoked with fumes from burning magnesium to coat it with magnesium oxide and is spaced from the screen 21 by glass beads 24. The screen 21 is an incandescent screen of thin refractory sheet or knitted fabric of refractory wire of À00025 inch diameter. Electrons from the cathodes 26 have low velocities and build up a negative charge on the grid 16. High-velocity electrons from the gun 2 release secondary electrons from the grid 16 and form local positive charges allowing electrons from the gun 2 to pass to the screen. The beam from the gun 2 is focused by a coil 12, deflected by plates 7, 10 and modulated by picture signals on a grid 4 so that these positive charges correspond to the picture and leak away in slightly less than one scanning cycle, an intense flow of electrons from the cathodes 26 to the screen 21 resulting. The charges built up on the grid 16 depend on its bias, and negative charges corresponding to the picture may form on the back of the grid. The beam from the gun 2 may be unmodulated and the picture signals may be applied to the grid 16.

[Class 3 (i).] A stock or like control board or indicator comprises a plurality of endless spring-tensioned display bands 5 each running over independent rollers 6, 7. Each band is perforated along one edge 8 to engage teeth on the roller 6, and carries a pointer 9 which rides along a scale 12, and pushes slidable indicators 15, 16 to maximum and minimum positions. The band 5 is coloured differently on different sides of the pointer 9. Fixed to each roller 6 is a pinion 22A which is normally locked by a detent 32 to prevent movement of the band 5, but which can be released by pressing inward a plunger 26 which carries the detent 32. The pinion 22A is in mesh with pinions 23A, 23 mounted on a plate 25 hinging about the roller spindle 24, and is made interchangeable to adapt the band to stocks of different value. On pressing in the plunger 26 against a spring 40, an adjustable eccentric 26A bears on the plate 25 and brings the pinion 23 into engagement with a pinion 28 on a shaft 27. A spring-pressed pawl 30 normally locks the pinion 28, but releases the pinion when its plunger 26 is pushed in. The shaft 27 serves as a prime-mover for operating a totalling mechanism, composed, for instance; of perforated graduated tapes 38, which display at a glass panel amounts in pounds sterling. Rods 17 slid longitudinally by ramps 31 on the plungers 26 bear each two symbols of different colour, one or the other of which is displayed at an aperture 19 to indicate whether or not a movement of a band 5 has taken place. The whole of the rods 17 are returned to normal position at the start of each control period by a vertical bar 20 pivoted on links 21 actuated by a pusher 22.
