Title: Improvements in and relating to starting devices for electric discharge lamps
IPC: H05B41/06
Filed: 1942-10-12
Abstract: 567,177. Control systems for discharge lamps. BRITISH THOMSONHOUSTON CO., Ltd. Oct. 12, 1942, No. 14277. Convention date, Oct. 11, 1941. [Class 38 (iv)] A discharge lamp with thermionic electrodes 13, 14 has a starting device 10 in series with the electrode heating circuit and in shunt with the electrodes and comprising two thermally movable members, such as bimetallic strips, one, 29, of which is quickly heated by a resistance 36 when the lamp circuit is closed to cause it to contact with the other 44 and establish an electrode heating current. This current heats the member 44 causing it to break the contact and produce the starting impulse. Should the lamp start, the apparatus is effectively short-circuited by the discharge, but otherwise the cooling of the member 44 recloses the heating circuit, which quickly opens again to produce another starting impulse. The apparatus is enclosed so that the heat accumulates and eventually prevents further attempts to start. Both members 29, 44 are arranged to move in the same direction with increase of temperature so that the apparatus is independent of ambient temperature conditions, in that the electrode heating time will vary with the temperature to which lamp and switch are exposed so that a suitable electrode temperature is reached at the time of the first starting impulse. A similar change of heating time occurs with a variation in supply voltage. The member 44 preferably has a carbon contact element 43 arranged to pass into an aperture in a supporting plate 28 which limits the movement of the member 29. A fixed contact may co-operate the member 29 to switch a second heater into series with the heater 36 after a short movement of the member.

Patent GB-143891-A (GB)
Title: An improved process for the manufacture of acetaldehyde from acetylene
IPC: C07B61/00
Filed: 1920-05-27
Abstract: In the manufacture of acetaldehyde by passing acetylene into acid solutions containing mercury salts, the catalyst is continuously regenerated in the reaction liquid by electrolytic oxidation, the arrangement being such that excess of metallic mercury is always present at the anode.  The reaction liquid may contain large quantities (over 10 per cent) of mercury salt, the rapid reduction of such concentrated solutions to mercury being offset by the anodic oxidation of the reduced mercury.  Examples are given in which (1) the liquid contains at the commencement both dissolved mercury salt and a mercury anode; (2) the liquid at the start contains only mercury salt, the reduced mercury collecting and being oxidized at a platinum anode; (3) the liquid at the start contains only a mercury anode, the current of acetylene not being passed until sufficient mercury salt has been formed by the electrolysis.  Sulphuric acid is employed as reaction liquid in the above-mentioned examples, but other inorganic or organic acids may be used.  The cathode may be of mercury, lead, platinum, &c., and may be enclosed in a diaphragm chamber or not.
