Filed: 1972-05-19
Abstract: 1380020 Lifting installations COMMISSARIAT A L'ENERGIE ATOMIQUE 18 May 1973 [19 May 1972] 23729/73 Heading F4R A lighting installation comprises a dustproof housing 2, a light source 10 and at least one heat exchanger, 14, 16 through which fluid is passed to cool the gas filling the housing. The exchangers 14, 16 may be located between the housing and a reflector 24, cooling the gas, which may be air, by convection. Alternatively, in the case of powerful sources, e.g. in excess of 3 kw, forced air circulation may be achieved using a fan 50. The source 10 may be a xenon arc tube. The exchangers may be watercarrying parallel tubes surrounded by cooling fins. Filtered air may enter the housing at 32 to give a superatmospheric pressure within the housing, vents being included in the end plates at 34. The light exit 4 may have an infra red glass filter 36 and a panel of toughened glass 38.

Title: Nitric acid neutralisation - using a thermal siphon and a pressure pump
IPC: C01C1/18
Filed: 1972-06-12
Abstract: Appts for neutralising nitric acid with ammonia using a thermal siphon and a pump comprises reaction reservoir contg. an aqs. medium and having one exit for vapour and one for the pdt. an inner cylindrical chamber projecting above the level of the reacting liquid and having an entry point below the level of the middle of the reaction region and an exit point above the middle of the reaction region. The apparatus has a device for bringing ammonia into the reservoir close to this entry point, so that it is moving in the direction of the entry point, and a device for introducing nitric acid into the main chamber at a distance far enough away from the central entry point to avoid immediate contact between the incoming nitric acid and the incoming ammonia. The HNO3 entering the second reaction zone has a concn 15% so that most of the acid is a neutralised in the second reator. The appts also contains a device for accelerating the circulation within the chamber due to the heat of reaction and the difference of density produced.
