Title: Method and apparatus for removing gaseous and readily vaporizable materials from liquids
IPC: B01D19/00
Filed: 1947-06-03
Abstract: Gases are removed from liquids in an apparatus comprising a chamber having an inner 39, and an outer 31 shell, a baffle 37 therebetween, openings 44 whereby the liquid enters the inner shell out of contact with a stripping medium, an ejector 38 whereby the liquid is entrained in the stripping medium entering through a nozzle 29 for further stripping, a sump 51, vanes 49 whereby part of the liquid is removed from stripping medium draining means 58, and a gas outlet 56. In operation, liquid enters through pipe 43 and passes over plate 41. On dropping therefrom it is broken up as a mist and hurled against shell 31 whereon it forms a film and passes down to and along the baffle 37 whilst being scoured by the stripping medium.  It passes through opening 47 to a skirt 46, drops therefrom and is atomized as a spray.  The process is an alternation of spray and film-formation until the openings 44 are reached, whence the liquid falls down through the inner shell until again atomized by incoming gas which carries it upwardly to the vanes where part of the liquid drains into the sump 51 whilst the remainder is recycled.  The chamber is kept under pressure, and both liquid and stripping medium are heated.  The treated liquid is removed from the sump and cooled by heat-exchange with liquid to be treated.  In the example an edible oil is deodorized but amongst the applications of the apparatus are de-aeration of liquids, deodorization of milk, animal oils and vegetable oils, removal of absorbed gases from liquid absorbents and undesired fatty <PICT:0648310/III/1> acids from fats.  The stripping medium may be steam, nitrogen or other inert gas.
Patent GB-617911-A (GB)
Title: Improvements relating to apparatus for controlling the distribution of fuel in aircraft
IPC: B64D37/08
Filed: 1946-05-16
Abstract: 617,911. Automatic control systems. SMITH, S. J. May 16, 1946, No. 14778. [Class 38 (iv)] A system for controlling the volume of liquid in each of two tanks, particularly the distribution of fuel in the tanks of an aircraft, comprises a condenser, whose capacity is proportional to the volume of liquid in the tank, situated inside each tank, and means responsive to the ratio of these capacities for controlling means for varying the volume of liquid in the tanks in such a way as to maintain the ratio of these volumes at a desired value. As shown, the tanks A and B have condensers 1a, 1b respectively, both of these, together with reference condensers 5a, 5b, being energized from a common A.C. supply 8. The measuring system employed is the same for each tank and is described in Specification 560,872, [Group XXXVI]. The condenser currents are passed through the primary windings of transformers 3a, 6a and 3b, 6b, the secondaries of which feed rectifiers 4a, 7a and 4b, 7b, the output being applied to ratiometer instruments 2a, 2b, which are calibrated to indicate the volume of fuel in each tank. The secondary windings of the transformers are connected to the grids 9a, 9b of a twin diode amplifying valve 10, the anodes of which feed the grids of push-pull connected rectifying valves 14a, 14b, feeding the two opposing field windings 15 of a control motor 16. If the capacities of the tank condensers are -not in the correct ratio, the field balance is disturbed and the control motor, the armature of which is continuously energized, rotates and operates a slide 19 on a potential divider 20 which governs the relative speeds of a pair of motors 21a, 21b. These motors drive pumps 24a, 24b, withdrawing fuel from the tanks A, B, respectively and restore the desired volume ratio. The arrangement is made self-balancing by connecting the control motor to a slider 22 on a further potential divider which alters the screen grid potential of valves 14a, 14b, in such a sense as to offset the changes due to the valve 10. An over-riding manual control acting on the valve circuits may be provided.

May 21, 1935, No. 14815. [Classes 122 (ii) and 122 (iii)] [See also Group I] In apparatus in which pneumatic pulsations are employed, the pulsations are produced and controlled by a pulsator comprising a pendulum mounted on movable bearings which co-operate with pulsation producing means in such manner as to produce the pulsations by converting a constant pressure or suction into regular pulsations of pressure and suction and to impart an operative movement to the pendulum. As shown, the pendulum 1, 2 is supported from a ported and channelled block 4 which controls the pulsations applied to the system by reciprocating on a base plate 7. The block 4 has channels 4a, 4b communicating each with a chamber 5a, 5b closed by a diaphragm 6a, 6b attached to the block 4, pulsations in the chambers 5a, 5b operating the diaphragms and reciprocating the block 4. The body 8 of the device has a channel 8c connected to a nipple 12 which communicates with vacuum, the chambers 5a, 5b being alternately related to vacuum by a slide valve 9 which is reciprocated by an extension 2a, 10 of the pendulum and has a port 9c which is in communication with the suction channel 8c to which it alternatively relates channels 4a, 4b. The channel not connected to vacuum is related to atmosphere through an open-topped passage 9a, 9b preferably covered with gauze. The block 4 has a passage 4c which alternatively connects nipples 11, 13 communicating with the system to which the pulsations are to be applied with the suction channel 8c, the nipple not connected to vacuum being related to the atmosphere through a passage 4e. The extent of the reciprocation of block 4 may be set by limiting the extent of the movement of diaphragms 6a, 6b. The block 4 may alternatively have an arcuate movement. A modified form of pendulum may be employed having a lower portion which is pivotally suspended from the upper portion in an axis lying in a direction at right angles to that of the axis on which the pendulum is suspended from block 4.

Abstract: 903,350. Coated sheet material. LOWE PAPER CO. Oct. 24, 1958 [Oct. 25, 1957], No. 14889/62. Divided out of 902,664. Addition to 870,224. Class 140. Sheet material comprising coated polyolefinic material, other than polyethylene, is prepared by conveying a film of the material continuously first through an activating zone in which the film is subjected to a surface-activation treatment and then through a coating zone in which a hydrophilic coating is applied to the activated surface. The expression " polyolefinic material " is defined as homopolymers of aliphatic monoethylenic unsaturated hydrocarbons and copolymers of two or more such unsaturated hydrocarbons, such as one or more lower alkene monomers, either straight or branched chain, e.g. polypropylene, polyalphabutylene, polyisopropyl propylene and polyisopropyl butene. The surface activation treatments include heat treatment with an open flame, exposure to ozone, chlorine, certain acids and/or electron bombardment. The hydrophilic coating may comprise starch, carboxymethyl cellulose, " Methocel " (Registered Trade Mark), proteins, e.g. gelatine, soybean protein, or casein, polyvinyl alcohol or acetate. Molten polyolefinic material may be extruded to form a film which may be continuously surface-activated and coated. The film as passed through the zones may be united with a backing of another material, e.g. paper, boxboard, kraft paper, cloth or " Cellophane " (Registered Trade Mark). The backing material may be continuously extrusion-coated with the polyolefinic material prior to the activation and coating. The extrusion coating may be performed by feeding the backing material into a nip formed between a drum and a roller, into which nip the polyolefinic material is extruded. The hydrophilic coating may also contain pigments, clay, fillers, and butadiene-styrene. The coating may be subsequently subjected to a brushing or buffing operation.
