Title: Improvements in the treatment of liquids
IPC: B01D15/00
Filed: 1923-05-26
Abstract: The Specification as open to inspection under Sect. 91 (3) (a) comprises a process for the purification of a gas consisting in subjecting it to the action of a plurality of active carbons possessing different physical and physico-chemical properties and so chosen that they supplement one another in their action.  The different types of carbon may be employed in admixture with one another or consecutively.  An example is given describing the removal of hydrogen sulphide and benzol from illuminating gas by the use of a mixture of two kinds of active carbon.  The benzol can afterwards be recovered by treatment with superheated steam or by heat, and sulphur resulting from the oxidation of hydrogen sulphide by the oxygen in the charcoal may be recovered by means of superheated steam or removed by oxidation.  This subject-matter does not appear in the Specification as accepted.ALSO:Liquids to be purified are subjected to the action of a plurality of active carbons each more active than ordinary bone char and possessing different physical and physico-chemical properties so that they complement one another in their action. The different types of carbon, six of which are distinguished in the Specification, may be employed in admixture with one another or consecutively.  The invention is illustrated by reference to the purification of glycerine, oils and fats.  Glycerine is treated with a mixture of a carbon having good filtering properties, e.g. that sold under the name "Norit" and one possessing good decolorizing properties e.g. the carbon known as "Carboraffin" or that known as "Suchar."  The carbons employed may be treated with substances that are capable of enhancing their effect or of preventing undesired subsidiary reactions.  For example, oils and fats containing fatty acids may be treated with a mixture of active carbons, one of which has been impregnated with lime.  Specification 163,505 is referred to.

Patent GB-686607-A (GB)
Title: Improvements in or relating to electrical temperature regulating apparatus
IPC: G05D23/24
Filed: 1950-06-09
Abstract: 686,607. Automatic temperature control systems. GARRETT CORPORATION. June 9, 1950 [July 22, 1949], No. 14435/50. Class 38 (iv). In a system controlling the temperature of a chamber, the supply of a temperature changing medium to the chamber is controlled in accordance with electrical signals dependent on chamber temperature and the temperature of the medium prior to entry to the chamber, the latter signal being derived through a gridcontrolled electronic valve. In Figs. 1 and 4, to maintain constant the temperature in an aircraft cabin 10, a resistance 21, variable with temperature in the cabin, is included in an A.C. bridge circuit 25, the output of which, when unbalanced on temperature deviation, controls, through an amplifier 36 and an A.C. operated double-triode 35, a pair of relays 56 to energize the appropriate one of two field windings 38 of a reversible D.C. motor 16, which thereupon drives a proportioning valve 15 in the appropriate direction to correct the temperature deviation by adjusting the mixture in a duct 11 of hot and cold air supplied to the cabin through ducts 12 and 13, respectively. Cabin temperature is maintained at a value determined by the setting of an adjustable resistance 26. Automatic control may be rendered inoperative and motor 16 run in either direction by manual operation of a selector switch 46. Auxiliary contacts 60 of relays 56 control the connection of a negative bias source 62 for double-triode 35 to produce intermittent operation of motor 16, the period of each operation being dependent on the time constant of a resistance 69 and condenser 71 and the interval between operations being dependent on the time constant of the entire biasing circuit. With this arrangement the period of operation increases and the interval between operations decreases with increase in output from bridge circuit 25, i.e. with increase of temperature deviation. The voltage of bias source 62 may be adjusted to give continuous operation of motor 16 upon large temperature deviations. The extent of unbalance of bridge 25, i.e. the magnitude of temperature deviation, necessary to produce operation of motor 16, is adjustable by varying a second bias source 72 for double-triode 35. To anticipate the effect of changes of ambient temperature and changes of temperature in duct 11, temperature-variable resistances 23, 22, respectively, in series with fixed resistances 102, 92 across A.C. sources, form potential dividers, the outputs of which are rectified at 115, 105 and applied through differentiating circuits 97, 96 to the grid circuits of triodes 120, 110 forming part of an A.C. bridge circuit, the output of which is added to the output of bridge circuit 25 and serves to correct for the effect of changes of ambient and duct temperatures on cabin temperature, variable resistances 118, 108 being adjusted to give a suitable time constant.
