Title: Improvements in or relating to the stabilisation of fat-soluble vitamin-containing marine oils
IPC: C11B5/00
Filed: 1945-03-27
Abstract: Fat-soluble vitamin-containing marine oils (which have not been treated or refined in such a manner as to remove all of the antioxidant constituents or constituents capable of having antioxidant properties imparted to them) are stabilized against oxidation by treatment with a small amount of ammonia without the addition of an antioxidant.  The process may be carried out by heating the oil under reflux in the presence of a solvent, for example, acetone, hexane, heptane, octane, ethylene dichloride, trichlorethylene, carbon tetrachloride cyclohexane, methyl cyclohexane or benzene.  The ammonia may be used in aqueous solution or anhydrous, in the amount equivalent to 1-10 per cent., calculated as concentrated aqueous ammonia.

Title: Improvements relating to the measurement of fluid flow
Inventor: SCANES PERCY
IPC: G01F1/80
Filed: 1955-03-17
Abstract: 815,645. Rotary meters. KENT Ltd., G. March 16, 1956 [March 17. 1955], No. 7808/55. Class 110 (2). A rotary meter, Fig. 1, for measuring the mass flow of a fluid comprises a rotor 2 having blades 3 disposed parallel to the direction of flow and a driving rotor 4 therefor having adjustable blades 5, the drive between the rotors being transmitted by a pivoted-link mechanism 6, 7, 8 which incorporates weights 10 and permits relative rotation between the rotors. The link mechanism is disposed between the shaft 15 of the rotor 4 and the hub 9 of the rotor 2 and imparts a torque T2 to the latter in opposition to a torque T1 imparted thereto by the fluid. The arrangement is such that when the torques are unbalanced the rotors are rotated relative to one another to adjust the blades 5 through gear means 13 whereby rotation of the spindle 15 remains proportional to the mass flow of the fluid in the conduit 1. The spindle 15 drives a counting mechanism 16 through gearing 14. In a modification, Fig. 3 (not shown), the blades 5 are fixed and a stator member having adjustable guide blades is disposed between the rotors 2, 4. In a second modification, Fig. 4, the blades 5 of the rotor 4 are again fixed and a modified weight mechanism, see also Fig. 5 (not shown), is used to control a diversion of the fluid flow through an opening 28 in the rotor 4 to thereby vary its speed of rotation. The flow is accordingly controlled by piston and cylinder means responsive to the pressure differential across the rotor 4. A passage 35 interconnecting one side of the piston with the upstream side of the rotor is controlled by a flap valve 38 which is under the joint control of the weight mechanism and the rotor 2. The rotor 2 may be driven by an electric motor having a rheostat control responsive to the torque variations.

IPC: C10G73/06
Filed: 1951-04-05
Abstract: Hydrocarbon oil is dewaxed by mixing the oil with a solvent which dissolves the oil at the dewaxing temperature, chilling to crystallize waxes, filtering to obtain a primary wax filter cake, separating a soft wax fraction therefrom by repulping the wax cake in the solvent at a temperature 10-40 DEG F. above the dewaxing temperature, but not at a temperature greater than 25 DEG F., and combining the separated fraction with the dewaxed oil.  Solvents referred to are petroleum naphtha, gasoline, a mixture of light hydrocarbons, methylene chloride and a mixture of an aliphatic ketone, such as acetone, methyl ethyl ketone or methyl isobutyl ketone and an aromatic hydrocarbon such as benzol or a mixture of benzol and toluol.  The filtrate containing the soft wax fractions is preferably recycled to the primary dewaxing operation, or may be mixed directly with the dewaxed oil; alternatively part is recycled and part mixed with the dewaxed oil.

[Class 118 (ii)] A vehicle warning system comprising an audible warning device equipped with a diaphragm and in association therewith an electromagnetic wave transmitter is characterised by the feature that the physical phenomena which produce vibrations of the said diaphragm or the vibrations themselves are utilized to modulate the high-frequency current of the electromagnetic wave transmitter. In the embodiment of Fig. 1 the ignition coil 2 supplies high-frequency currents to the sparking- plugs 6 and also to an aerial transformer 8. The radiated frequency is modulated by a vibrating contact 10 operated by the vibration of the diaphragm of the vehicle's audible warning device. The contact 10 may be integral with the interrupter of an electromagnetic horn and arranged to open when the interrupter contacts close. The modulating contact 10 may be shunted across the aerial transformer 8, Fig. 2 (not shown). In a further embodiment, Fig. 4 (not shown), an oscillatory circuit is connected across the interrupter contacts themselves, operation of the vehicle horn producing an oscillatory current which is fed to an antenna. In a further embodiment, Fig. 3 (not shown), the audible warning device is arranged to interrupt the primary ignition circuit, in addition to the normal interrupter, thus modulating at audio-frequency the hightension current in the ignition secondary circuit, which is coupled to an aerial.
