Patent GB-563076-A (GB)
Title: Radio beacon
IPC: G01S1/02
Filed: 1940-08-21
Abstract: 563,076. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 21, 1940, No. 13290. Convention date, Oct. 11, 1939. [Classes 40 (iii) and 40(v)]. In radio beacons producing overlapping radiation patterns having distinguishing characteristics, e.g. using directive antennµ radiating interlocking signals, distortion due to reflection from nearby objects is reduced by varying the carrier frequency within predetermined limits (wobbling), The frequency variation may amount to 1 per cent and may be produced by modulating a fixed carrier frequency by a variable frequency auxiliary oscillation so as to produce two side-bands, each of which varies between fixed limits determined by the auxiliary oscillator. The two side-bands may be transmitted from the two directive antennµ respectively, each being given a distinguishing modulation at the transmitter or at the receiver. This distinguishing modulation may be effected by the use of band rejection filters arranged in the feeding paths of the separate antennµ, the number or character of the filters in each path being different, so that the two radiations are distinguished. In Fig. 1, a generator 10 of varying frequency is connected to directive antennµ 13, 14 through modulating condensers 15, 16 which are driven by a motor 17 and produce different signal characteristics in the two beams. In Fig. 2, a generator 20 of varying frequency is connected to antenna 23 through a rejector filter circuit 25 which suppresses the energy radiated at one particular band of frequencies, the generator being connected to antenna 24 through two filter circuits 26, 27 which suppress the energy radiated by 24 at two frequencies different from that of 25. This gives different signal characteristics to the two beams, Fig. 4 (not shown). Signals of the A-N type may be produced in this way. The band filter may consist of a transmission line 30, Fig. 3, coupled to a transmission line 31 tuned to the frequency it is desired to suppress. In Fig. 6, oscillations of frequency f from generator 60 are modulated at 61 by oscillations of varying frequency F1 # F2 from oscillator 62, thereby producing side bands of frequencies (f + F1 # F2) and f - F1 # F2) which are fed to antennae 64, 65 respectively. The carrier frequency may be suppressed by band filters 68, 69, and characteristic modulation impressed on the beams by filters 601 ... 606 as described in connection with Fig. 2. The frequency F1 # F2 may vary from 500 to 500,000, or even from 0 to 500,000. In a further system, Fig. 7 (not shown), in which the two side-band frequencies are widely separated, the carrier may also be modulated by speech or other audio frequencies, this energy being radiated from both antennµ and sorted out at the receiver by tuned circuits. Receivers for the various systems are described but are of little general interest.

Title: Method of manufacturing polyolefin composition foamed bodies
IPC: C08J9/10
Filed: 1965-03-31
Abstract: Foamed bodies of polyolefines are made by homogenizing a mixture of a polyolefin, with optionally up to its own weight of another plastic and/or a rubber, an organic peroxide and a blowing agent, heating under pressure so as to cross-link the polyolefin and decompose the blowing agent, cooling under pressure to a temperature below the softening point of the polymer, the pressure always being sufficient to prevent any expansion occurring, and finally reheating without pressure to cause foaming and expansion.  Specified polyolefines are polyethylene, ethylene/propylene copolymer, ethylene/butene copolymer and ethylene/styrene copolymer.  Specified rubbers and/or plastics are natural rubber, EPR, butyl rubber, polyisobutylene, SBR, polybutene, polybutadiene, ABS resins, polystyrene, chlorinated or chlorosulphonated polyethylene, polypropylene, ethylene/vinyl acetate copolymer and ethylene/ethyl acrylate copolymer. Specified organic peroxides are dicumyl peroxide, 2,5 - dimethyl - 2,5-di(tertiary butylperoxy) hexane, di-tertiary butyl perterephthalate and tertiary butyl hydroperoxide.  Organic compounds which decompose to give nitrogen may be used as blowing agents, alone or together with NaHCO3 or organic low-boiling liquids.

Title: Process for purifying phenolic acid oils
IPC: C07C37/86
Filed: 1960-04-20
Abstract: Catalysts for use in purifying alkaline solutions of acid oil, consisting substantially of phenolic compounds and carboxylic acids containing mercaptans (see Group IV(b)) comprise phthalocyanine sulphonates or carboxylates supported on a carrier.  Metal phthalocyanine sulphonates and carboxylates are preferred, e.g. those of iron and copper and in particular cobalt and vanadium phthalocyanine sulphonates.  Carriers specified include various charcoals, coke, silica, alumina and silica-alumina composites.  The latter usually being activated by acid on heat-treatment.  The catalysts are prepared by treating particles of the solid carrier with solutions of the phthalocyanines.ALSO:In a process of purifying an acid oil consisting substantially of phenolic compounds and carboxylic acids and containing mercaptans as contaminants, an alkaline solution of said acid oil containing mercaptans is subjected to an oxidizing treatment with a gas containing free oxygen in the presence of a phthalocyanine sulphonate or carboxylate catalyst at a temperature of from atmospheric to 205 DEG C. whereby the mercaptans are converted to disulphides and thereafter the resulting disulphides are separated as an upper layer or extracted by a normally liquid hydrocarbon fraction from said alkaline solution and the phenolic compounds are recovered from the purified alkaline solution. Preferred catalysts are commercial cobalt phthalocyanine disulphonate containing the monosulphonate and vanadium phthalocyanine sulphonate. Other metal phthalocyanine sulphonates and carboxylates specified include those of iron and copper.  Such compounds may be prepared by reacting the corresponding phthalocyanine with fuming sulphuric acid. Carboxylated catalysts may be prepared by the action of trichloracetic acid or of phosgene and aluminium chloride or the corresponding phthalocyanines, the acid chloride formed in the latter reaction being converted to the acid by hydrolysis.  As alkaline solvents are specified aqueous solutions of sodium, potassium, lithium, rubidium, caesium and ammonium hydroxides.  The catalyst may be in solution in the aqueous alkali or associated with solid carriers representative of those mentioned being charcoals, coke, silica and alumina which may be activated by treatment with acid or heat. The examples relate to the treatment of alkaline solutions of acid oils obtained from cracked gasoline, kerosene and coke oils. Apparatus for carrying out the process is described with reference to a flow sheet (not shown).
