Abstract: 473,166. Television. TOULON, P. M. G. Nov. 6, 1936, No. 30330. Convention date, Nov. 6, 1935. [Class 39 (i)] Electron - discharge scanning - apparatus for a transmitter comprises at least two grids 4, 5 and 6, 7, interposed between a lightsensitive cathode 1 on which the image to be scanned is projected and an anode 3. Batteries 8, 12 are connected to the ends of the grids, which are made of resistance wire or mesh, so as normally to produce uniform and opposite potential gradients along the grids, with the effect that there is only one point on the cathode from which electrons can proceed to the anode. By applying a scanning frequency potential wave to the grids, the said point shifts along the cathode, thus giving a scanning action. The scanning voltage may be applied via a coil 21 by any suitable means such as the oscillator circuit shown, comprising a valve T, the grid of which receives periodic synchronizing impulses. In the arrangement shown, images on a film F are projected on to the cathode, the movement of the film providing one component of scanning. The discharge device may, however, be modified to give both components by providing two mutually perpendicular grids, functioning in the manner described, two relaxation oscillators being provided to superimpose voltages at line frequency and frame frequency respectively on the grids.

IPC: C08G8/28
Filed: 1927-11-15
Abstract: 288,228. Runstharzfabrik Dr. F. Pollak Ges. April 6, 1927, [Convention date]. Phenol-aldehyde condensation products. - In the production of condensation products in the form of a pulverous precipitate from phenols and aldehydes, the condensation is carried out in the presence of dispersively acting substances, such as gum arabic, saponin, tragacanth, dextrine, gelatine, casein or other protective colloids, preferably in dilute solution. The condensation product first forms as small drops, suspended in the liquid, and assumes a pulverulent character on continued heating. This suspension may be poured into water or into solutions of salts or acids, or cooled when a pulverulent product is precipitated. Condensing agents, preferably of a basic character, may be employed, and the condensation is preferably effected in the presence of neutral salts. In a typical example, metacresol mixture and, formaldehyde (30 per cent by weight) are mixed with gumarabic dissolved in water, heated, and twice normal caustic soda solution is added. The finely divided oily condensate is boiled until it assumes a fine pulverulent form. By the addition of cold water or dilute acid, a sand-like powder is precipitated which is filtered off. Other examples are given, in one of which a precipitate insoluble in alcohol or alkalies is formed by continued boiling. Other aldehydes such as acetaldehyde, furfural, acrolein &c. may be used.

Abstract: 200,756. Mills, G. L., and Mills, S. E. Nov. 13, 1922. Sprinklers, automatic; water supply to distributing systems.-Automatic control apparatus of the type adapted to supply steam to a pump for increasing the pressure in a sprinkler installation in the event of such pressure falling below a predetermined level comprises a casing 1 connected with the main steam supply pipe 2 and provided with an inner cylinder 3, in which slides a combined piston and beat valve 5, the stem 7 of which also carries a piston 10 of greater diameter than the piston 5. Normally, the valve 5 is held against its seat by a spring 12 and by the pressure of steam in the chamber 11, which is connected through a passage 14, a valve 16, a chamber 22, and a branch pipe to the main steam pipe 2. If the pressure in the sprinkler installation falls, a diaphragm 19 connected thereto by a pipe 21 recedes under the action of a spring 25, thus closing the valve 16 and opening a valve 17, the steam in the chamber 11 thus escaping through a chamber 23 and an exhaust pipe 23a. The steam pressure then opens the valve 5, and steam passes through ports 4<a> into a space 9, thence through ports 4, 6 to the interior of the valve 5, and finally through a pipe 26 to the steam pump. When the pressure in the installation is restored, the diaphragm 19 closes the valve 17 and opens the valve 16, thus causing the valve 5 to close and shut off the steam supply to the pump. The control apparatus may be designed to operate periodically every fiew hours by means of an automatic tank and ball valve device adapted to reduce the pressure in the installation main at any required interval.
