Abstract: 1470549 Aerating liquids L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 24 June 1974 [25 June 1973] 27997/ 74 Heading B1C A method of treating a liquid (e.g. effluent) with oxygenating gas in a sealed container comprises regulating the quantities of fresh oxygenating gas and recycled oxygenating gas as a function of three parameters, namely the pressure of the atmosphere within the container; the proportion of oxygenating gas in the container atmosphere; and the quantity of oxygen in the liquid. The parameters may be sampled in succession. As shown the liquid in a tank 1 is treated with oxygenating gas O 3  made up partly of recycled gas O 2  and partly of fresh gas O 1  admitted through a valve 7 operated by a controller 10. The pressure P above the liquid is first sensed; if above a pre-determined value the valve 7 is closed and only recycled gas is supplied. If lower, measurement of the oxygenating gas in the container atmosphere, O a , takes place; if this is above a predetermined value only recycled gas continues to be supplied. If below, measurement of the oxygen O e  in the liquid takes place. If this is above a predetermined value which constitutes the upper limits of a coating range, only recycled gas continues to be supplied. If below this value and within the working range, the valve 7 is opened to supply also fresh gas. If below the lower limit of the working range, the supply of recycled gas is also increased as by starting up additional compressors 14, 16. In another embodiment (see Fig. 2, not shown) additional compressors are not provided but the oxygen level of the recycled gas is raised by increasing the predetermined value O a . The working range for O e  may be 2.5-6 ppm and P may be 30 cms of liquid in the tank.

Title: Improvements relating to electrical remote control and signalling systems
IPC: H02J13/00
Filed: 1926-06-08
Abstract: 280,485. Siemens Bros. & Co., Ltd., and Humphries, H. E. June 8, 1926. Drawings to Specification. Selective distant control systems; tell-tale apparatus.-Relates to a system for controlling and supervising apparatus located at a plurality of remote stations connected across common control and supervisory line wires. The system described is identical with that described in Specification 280,254 but the claims relate to means for effecting the selection of an apparatus unit at a substation and maintaining the selection in order that the condition of the unit may be regulated at will. For example, apparatus may be selected which effects the reversion of the voltage of a circuit to the control point and whilst such voltage continues to be reverted, the apparatus may be regulated to alter the voltage. Operation of a key to effect the desired selection, initiates the transmission of two trains of impulses characteristic of the substation and apparatus respectively. This operation automatically connects the line wires to the circuit, the condition of which is to be reverted, and the appropriate meter. Operation of a regulating key then initiates the transmission of a further impulse train which is characteristic of the nature of the regulation to be effected e.g. " raise " or " lower." After a pause, a further train of impulses, which continues only so long as the regulating key is operated, is transmitted to cause the regulation. Specification 230,291, [Class 40 (iv), Telephones &c.], also is referred to.
