Title: Improvements in or relating to the production of fatty acids by oxidation of hydrocarbons
IPC: C07C51/225
Filed: 1930-12-18
Abstract: Fatty acids are obtained from products of the destructive oxidation of paraffin hydrocarbons of at least 8 carbon atoms, or of mixtures containing a preponderating quantity of such hydrocarbons, by saponifying the oxidation products and, preferably after removal of the unsaponifiable matter forming a supernatant layer on the resulting soap solution, subjecting the soap, either in the form of the solution or after drying and comminution, to extraction with liquefied paraffin hydrocarbon materials containing at least 10 carbon atoms in the molecule, preferably at a temperature between 50 and 110 DEG  C.  The hydrocarbon materials used for the extraction may be similar to the starting material subjected to oxidation, and may consist of liquefied paraffin waxes, paraffin oil, middle oils or similar fractions from the destructive hydrogenation of oils or tars. According to examples, (1) hard paraffin wax is oxidized at 70 DEG C. and 5 atmospheres pressure with nitrogen oxides, the product saponified at 200 DEG  C. with an aqueous soda solution, and the upper layer formed withdrawn.  The soap solution is extracted three times with paraffin wax at 100 DEG  C., and the supernatant layer of wax containing unsaponifiable constituents in solution removed and returned to the oxidation vessel; (2) paraffin wax is oxidized with nitrogen oxides at 60 DEG  C. and at 4 atmospheres pressure, saponified as at (1) above, and the soap solution allowed to flow down an extraction tower with paraffin wax of the kind used as initial material heated to 90 DEG  C. flowing in countercurrent, soap solution mainly freed from unsaponifiable constituents being drawn off at bottom of the tower; and (3) a distillate obtained by the destructive hydrogenation of American Mid-continent oil is oxidized with nitric acid.  The product is saponified with caustic soda solution, the upper layer separated, and the soap twice stirred with some of the original distillate to extract unsaponifiable constituents.  Specification 333,904, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in or relating to very short wave aerials
Inventor: GOODALL EDWIN GEORGE ALEXANDER
IPC: H01Q13/04
Filed: 1956-12-20
Abstract: 808,941. Aerials. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Aug. 16, 1957 [Dec. 20, 1956], No. 38824/56. Class 40 (7). An aerial giving an approximately hemispherical radiation diagram comprises a circular waveguide 1 having a mouth 2 and a T-sectioned dielectric member 3. The dielectric member has a tapered impedance matching section 31 about two wavelengths long extending into the guide to which the head end is joined by a cylindrical piece 32 roughly half a wavelength long which fills the guide mouth. The radiating head section has a conical depression with a wall 34 having an apex angle of about 120 degrees and a peripheral face 35 of a length of half the wavelength. The rear wall 36 of the head is parallel to the wall 34 so that the head is of constant thickness. It is intended that the aerial should be mounted with the guide 1 vertical and that for containing the waveguide mouth it should be fed with circularly polarized waves. The resulting radiation is circularly polarized in the direction of the axis of the guide and almost entirely vertically polarized in the plane containing the waveguide mouth. Dimensions are given for an aerial working on a wavelength of 3.2 centimetres.
Patent GB-389351-A (GB)
Abstract: 389,351. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. July 18, 1932, No. 20290. Convention date, July 16, 1931. [Class 40 (v).] Relates to a wireless navigation system of the kind in which synchronously-operated change-over switches kl, k2 control the input from an open aerial a and a frame aerial b in such a manner that the rectified output moves an indicating needle z to show whether an aviator is flying to the right or left of his correct course. According to the invention, the orientation of the frame-aerial is fixed relatively to the aircraft, and means are provided to allow for wind-drift, so that the aviator can " home on to the transmitter and maintain a zero reading on the indicator, even though he is actually heading into the wind. As the plane of the frame aerial is fixed, it can be stream-lined. The " course " adjustment is made either by inserting suitableresistances at the points x, x<1> in the connection between the detector d and indicator z ; or, as shown in Fig. 5, by introducing a directcurrent component from a potentiometer F between the driving-alternator C for the switch K and a polarized relay M. This varies the relative periods T1, T2 during which each of the aerials a, b is in circuit, so that at the indicator the datum line is raised from t to ig and the needle is kept at zero even though the plane of the frame aerial is inclined to the transmitter.
