[Also in Division B1] Apparatus for determining values of electrostatic field strength on a storage tank receiving liquids of low conductivity arising from charges generated by the passage of the liquids comprises a delivery line connected to the storage tank, a bleed line connected to the delivery line, and an electrostatic field strength connected to the discharge of the bleed line, the dimensions of the bleed line and the supply line downstream thereof and the position of the instrument being such that the residence time of liquid in the bleed line from the bleed off point to the position of the instrument is identical with that of the liquid in the delivery line downstream of the bleed point. In Fig.1 a storage vessel (not shown) for a low conductivity liquid e.g. hydrocarbon oil is connected over line 1 and filter 2 to discharge over delivery line 3 into an insulated vessel 4 connected to an earthed electrometer 6 and through a bleed line 7 following the filter into an insulated vessel 8 connected to earthed electrometer 10. The residence time of the liquid in the bleed line is identical with that of the liquid in line 3 downstream of the bleed line, and it is shown that if the electrostatic properties in the bleed line are similar to those of the delivery line the electrostatic currents in the discharge and bleed lines due to the passage of the liquid and the charges on vessels 4, 8 measured by the electrometers are proportional (Figs. 3 to 7 not shown) so that the charge and electrostatic field on vessel 8 measured by electrometer 10 are proportional respectively to those on vessel 5. In Fig. 2 a storage tank 11 is connected by line 12, valve 13, and pump 14 through filter 15 and flow meter 16 to storage tank 17. A bleed following the filter 15 is taken over line 18 to simulation tank 19 whose outlet line 20 is returned to the suction side of the pump and the lines 18, 20 are proportioned to maintain simulation tank 19 just filled. The residence time of the fluid in the bleed line is identical with that in the delivery line. An electric field meter 21 incorporated in the simulation tank generates signals proportional to the electrostatic charge thereon and as shown to that on the receiving storage tank which operate a recorder and an alarm (not shown) responsive to the level of charge on the storage tank due to the passage of the liquid. The signals may also electrically operate valve 13 to control the rate of delivery to maintain the electrostatic discharge on the tank at a predetermined safety level. Constructional dimensions and experimental results are given, and the apparatus is adaptable for use in refilling aircraft or road tankers with petroleum products.

Title: Improvements in or relating to livestock feeds and process for the manufacture thereof
Inventor: CAVANAGH GEORGE C
IPC: A23K10/37
Filed: 1955-10-18
Abstract: 817,834. Animal feeds. INTERNATIONAL RESEARCH & DEVELOPMENT CORPORATION. Oct. 18, 1955, No. 29675/55. Class 5(2). Livestock feed is made from a vegetable material, e.g. cottonseed, corn, soya beans, castor beans, linseed, peanuts, and safflower seeds, by a process comprising comminuting the vegetable material, extracting oil therefrom, and coating the extracted material with soapstock. A conveyor 10 passes the vegetable material, preferably comminuted, through a cooker 12 and thence to flaking rolls 20 where it is comminuted further. The rolls are connected to an extraction column 23 to which the vegetable material is passed to undergo extraction by means of a volatile solvent, e.g. n-hexane, introduced at the lower end of the column from source 25. Before extraction, however, non- toxic alkaline reagents exemplified by soda ash, sodium bicarbonate or hydroxide, disodium or trisodium phosphate or the correspending calcium or potassium salts, or urea, are passed from a hopper 29 and added to the vegetable material at 28. The reagents are said to interact with colour bodies, waxes, gums, a very small part of the free fatty acids, and gossypol, contained in the vegetable material, converting them from oil-soluble to water-soluble substances. These substances, together with vegetable material from which oil has been extracted, are removed by a conveyer 32 to a drier 34. The miscella, i.e. mixture of oil and solvent, passes through a filter 38 to a tank 39 and thence to a device 41 which regulates the mixing of miscella with aqueous caustic soda solution supplied from a tank 54. Sufficient caustic soda is added to neutralize free fatty acids contained in the miscella. Mixed miscella and caustic soda are passed to a homogenizer 60 where soapstock (crude soap) is agglomerated. After further agglomeration in an economizer 69 by successive heating and cooling, the mixture, now in two phases, passes to a centrifuge 74 in which soapstock is separated from the oil and most of the solvent. The soapstock containing small quantities of solvent adhering thereto passes through conduit 76 to the drier 34 to be mixed there with the residual vegetable material in a proportion of at least 1 per cent. by weight of residue. The solvent facilitates distribution of a film of soap stock throughout the vegetable material. Solvent and moisture are subsequently evaporated in the drier and the resultant meal is then suitable for use as a livestock feed or it can be first made into pellets in an apparatus 77. Specification 816,792 [Group III] is referred to.
