Filed: 1941-01-31
Abstract: 546,184. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 31, 1941, No. 1285. Convention date, Feb. 1, 1940. [Class 40 (v)] A multiple-course beacon for laying equisignal courses comprises two sets of aerials each providing a multiple-lobe polar diagram which is in turn formed by two dumb-bell shaped diagrams. The radiators B, B1, Fig. 1, each producing a dumb-bell polar diagram, are energized at different powers and produce a resultant diagram as shown in Fig. 2. Each radiator B, B1 may comprise a spaced pair of dipoles or a pair of horizontal' loop aerials as described in Specification 538,036. A set similar to BB<SP>1</SP> and placed at right angles thereto gives a similar diagram displaced through 90 degrees with the result that equi-signal courses 1 ... 4 are set up as shown in Fig. 3. Figs. 14 and 15 show in elevation and plan respectively the lay-out of the aerials. One set comprising a pair 11, 12 and a pair 17, 18 are energized from a transmitter 21 through a modulator 19 and through lines of different length which result in radiation of opposite phase from the pair 17, 18 relative to the pair 11, 12. The power radiated by the respective pairs is adjusted by loop sections 28. The set 13 ... 16 is similarly energized, a different modulation characteristic being applied at 20. The inner ring of aerials 12, 14, 15, 17 may be combined as a single aerial at the centre of the system (Fig. 16, not shown). If the spacing of the outer aerials from the centre one is half a wave-length, and the current ratio is as 10 to 6 the resultant polar diagram is that shown in Fig. 17.

Title: Production of chromic acetylacetonate
Inventor: BULLOFF JACK JOHN
IPC: C07F11/00
Filed: 1958-01-20
Abstract: Chromic acetylacetonate is prepared by reacting a solution of a water soluble chromic salt with acetylacetone in an aqueous alkali medium stabilised with an alkali metal carboxymethyl-dextranate against hydrous chromic oxide precipitation.  The product may be extracted by means of a solvent, e.g. chloroform or ether, and this evaporated to give crystalline chromic acetylacetonate.  The product may be used for depositing chromium and its compounds from the vapour state (see Group II).ALSO:Chromium metal, oxides, carbides or nitrides may be deposited from the vapour state using chromic acetylacetonate as a source of chromium.  Specifically, vapours of this compound directed on to a hot ceramic under vacuum conditions give a black deposit which on heating in air turns into green chromic oxide, while when the acetylacetonate is volatilised in air, green Cr2O3 is collected on a cold metal plate.
