The above 4-ol-1,7-dione can also be prepared by either of the following processes which are claimed:-by hydrolysing the corresponding 4-acylate with alkali; and by subjecting to acid hydrolysis a 4b-methyl-1,2,3,4,4a,4b,5,6,7,8,10,10a - dodecahydrophenanthrene - 4 - ol - 1 - one having in the 7-position a bivalent substituent or two univalent substituents convertible to keto by acid hydrolysis or a 4b - methyl - 1,2,3,4,4a,4b,5,6,10,10a - decahydrophenanthrene - 4 - ol - 1 - one having in the 7-position a univalent group convertible to keto by acid hydrolysis.  This process may be modified in that the reactant is prepared by a process described in Specification 763,210. Examples of bivalent substituents are cyclic ketal groups such as the ethylenedioxy, ethylene dithioketal and ethylene henithioketal groups, examples of two univalent groups are the non-cyclic ketals such as dimethyl ketal, and examples of a univalent group are enol ether groups such as the ethyl enol ether group in which case the reactant is a 1,2,3,4,4a, 4b,5,6,10,10a - decahydrophenanthrene compound.  Suitable reagents for the acid hydrolysis are hydrochloric and sulphuric acids and substances which give rise to acids such as p - toluene - sulphonyl chloride. The 4 - acylates of the above 4-ol-1,7-dione may be prepared by either of the following processes which are claimed:-by acylating the 4-ol-1,7-dione; and by oxidizing a 4b-methyl-1,2,3,4,4a,4b,5,6, 7,9,10,10a - dodecahydrophenanthrene - 1,4 - diol-7-one-4-acylate (which may be obtained by hydrolysing the corresponding 1,4,7-triacylate with methanolic potassium carbonate) with chromium trioxide.  The 1,4,7-triacylate for use in the above process may be prepared by a method claimed in Specification 763,209 in which case the resulting 4-acylate derivative of the above 4 - ol - 1,7 - dione may be stereoisomerized by treatment with a mild base such as sodium bicarbonate, pyridine, and alkaline alumina.  The preferred acylate, reactants and product in all the processes referred to above are the acetates.  A number of detailed examples are given. Specifications 736,307, 763,198, and 763,208 also are referred to.

Abstract: 534,066. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Dec. 22, 1939, No. 32811. Convention date, Jan. 9. [Class 40 (v)] A two-wire, coaxial, or hollow-pipe transmission line, for radiating or receiving short waves, is terminated by a " horn ", which has a flare-angle of predetermined value for waves of a given frequency, and is fitted with an exciting or absorbing " antenna ", so related to the flare-angle, and so positioned relatively to the throat and apex of the horn that waves of the predetermined frequency and up to a certain higher order of frequency are propagated whilst waves other than those desired are substantially attentuated. Figs. 1, 2 and 3 illustrate typical shapes of horns, and show different ways of disposing and coupling the antenna 14 and feed-line 10, 12 to them. The horns are suitable for equi-signal navigational work, or for " blind-landing " beams, owing to the absence of undesirable secondary lobes of radiation; and also for " guided " waves of the H01 and H10 type, where the electric and magnetic fields respectively lie parallel to the Y axis, Fig. 4. For a given flareangle # 0 , Fig. 4, a selected value of the cutoff length P 0  will permit waves of the H01 type to form and travel freely through the horn, but will attenuate or filter-out waves of higher order, e.g. of the H03, H05 &c. type. Optimum values for the constants of the horn, and the distance of the antenna 14 from its apex are specified for handling waves of a desired type and frequency with maximum attenuation of other waves.

Abstract: 1,048,475. Field effect transistors. RADIO CORPORATION OF AMERICA. Aug. 20, 1963 [Sept. 7, 1962], No. 32977/63. Heading H1K. A field effect transistor consists of a semiconductor substrate with a low-resistivity surface inversion layer of opposite conductivity type provided with two electrodes and a control electrode disposed on an insulating layer overlying the surface layer between the two electrades. A typical arrangement (Fig. 3) is made from a monocrystalline 500 ohm. cm. P-type silicon wafer 23a by chemically etching its surface, depositing thereon heavily donordoped silica by decomposition of a doped oxysilane, and selectively removing it by etching using photoresist techniques to expose certain portions. The wafer is next heated in dry oxygen for an hour to form thin pure silica layers 25a on the exposed portions with N-type inversion layers 27a beneath them and to form beneath the doped silica N-type regions 31a, 33a &c. making ohmic connection to the ends of the inversion layers. Apertures are etched in the doped oxide layers by conventional photoresist techniques, and aluminium vapour deposited over the entire surface and subsequently selectively removed to leave source and drain contacts 35a, 37a on the N regions and gate contacts 45 overlying the pure silica layers 25a. The gate contacts may be confined to the original apertures in the doped layer as shown or may extend slightly beyond them. The resulting devices are suitable for series connection. In an alternative arrangement (Fig. 8, not shown) every third gate electrode is omitted and the remaining ones connected together in pairs to provide a plurality of devices each with two source electrodes and a central drain electrode. The thickness and hence resistance of the inversion layers is determined by the duration and temperature of the heating step but the channel resistance may be further modified by baking the wafer in a dry inert atmosphere immediately before the electrodes are deposited. Characteristics of devices subjected to such treatments are given to illustrate their effect. An alternative device with a disc-shaped drain and concentric annular gate and source electrodes is also described (Fig. 1, not shown).
