In an electric discharge tube such as a vidicon or image orthicon - television pick-up tube in which a scanning beam of electrons is focused at the target 4 by a solenoid 11, a magnetic or magnetizable member or disc 7, e.g. of mild steel, is provided near the target to maintain the beam in focus over the target and to overcome the edge effects of the coil 11. A mesh electrode, serving as an ion trap or field mesh, may be arranged in contact with, and on either side of, the disc 7. Where in the vidicon shown, the target 4 comprises a solid layer of antimony trisulphide on a spongy layer of the same substance, the solid layer may be deposited by driving antimony trisulphide, which is deposited on the disc 7 and associated mesh during the deposition of the first spongy layer, on to the anode 5 and from there on to the target. These steps are accomplished by shifting an eddy current heating coil. Specification 984,673 is referred to.

Title: Improvements in the production of nicotine-free tobacco
IPC: A24B15/24
Filed: 1931-04-14
Abstract: A denicotined tobacco is obtained by leaching out the tobacco leaves with water or other liquid which does not interfere with fermentation, allowing the liquor to ferment under the action of air, and returning the liquor, preferably after concentration, to the tobacco.  The basic products, such as amino bases, formed during fermentation are neutralized continuously or at intervals by means of acids, such as lactic or tartaric acid, or acid-forming substances such as carbohydrates.  The fermentation takes place in shallow vessels and may be assisted by the addition of bacterial cultures.

A fire alarm system comprises a pair of normally open detector switches 50, 51, e.g. of the gas evolving type, connected in series with an alarm indicator 20 between a supply line 12 and earth, each switch being shunted by a " caution ' indicator 31, 32, or 36, 37. The alarm indicator has a low impedance compared with the caution indicators so that closure of both switches lights alarm lamps 20, and closure of only one actuates only the caution indicator associated with the other. The switches may be arranged to operate at different temperatures so that a " caution " indication is first given and, after a further rise in temperature, the alarm 20 is operated. The alarm 20 may be supplemented by a relay 26 operating an acoustic alarm. Actuation of one of the cautions may be caused by a fault condition by actuation of test switches 41, 42, 43 to disconnect either detector and replace it by a short circuit. A manual test switch 64 is also provided which actuates relay 62 to close contacts 65, 66 completing a test heating circuit.
