Abstract: A tuned mass damper (TMD) system in combination with a floating offshore wind turbine (FOWT) platform includes a barge type FOWT platform having a hull configured to have a wind turbine tower mounted thereon. A TMD system is mounted in the hull and has a first TMD configured to operate at a first frequency, and a second TMD configured to operate at a second frequency different than the first frequency.

Abstract: A video monitor includes a kinescope driver amplifier AC coupled to a kinescope via a capacitor which is also associated with a video signal clamp. A control signal related to the magnitude of video signals coupled to the kinescope modifies the kinescope bias so as to increase kinescope current conduction and image brightness, to counteract the tendency of a displayed image to exhibit reduced brightness as the amplitude of the video signal increases.

Abstract: A solid mixture of aldehydo-, keto-, carboxy-, carboxy-and-aldehydo-, and keto-and-carboxy-substituted benzene and toluene especially as obtained as residue from the manufacture of benzene di- and tricarboxylic acid is continuously subjected to pyrolysis at a temperature above 700.degree. C. with the production of a gaseous product and no substantial production of a solid carbonaceous char by adding such mixture as a suspension of comminuted solid in liquid water, but without an externally added catalyst, to a bed of inert, moving solids whose movement is stimulated by a gas flowing through said bed to fluidize, expand or make ebullient said bed of particles. Said gaseous product comprises hydrogen, carbon oxides, methane, benzene and toluene enriched in hydrogen and carbon dioxide content by the reaction of carbon and steam from the suspending liquid water thus substantially consuming the carbonaceous char which would otherwise be produced as a solid product.

Abstract: In the location of an earth fault on a sheath of an underground cable, pulses of direct current are applied to the sheath at one location on the cable. A search is made at spaced locations along the cable route for the magnetic field due to a fault current to earth flowing in the sheath which is produced by the applied d.c. pulses using a portable magnetometer, with a visual indicator, and, at each of said spaced locations, the visual indications on the magnetometer are compared with the periods of application of the pulses to the sheath until they correspond. Comparison of the visual indications with the periods of application of the pulses is facilitated by transmitting signals indicative of the periods of current application and using, with the portable magnetometer, a portable receiver arranged to receive the transmitted signals so that the visual indications can be compared with the received signals.

Abstract: Commercially attractive amounts of benzene and toluene can be obtained from a solid mixture of aldehydo-, carboxy-, keto- and carboxy-, carboxy- and aldehydo-substituted benzene and toluene including such mixtures also containing cobalt and manganese salts of organic acids and inorganic and organic bromides obtained from the manufacture of benzene di- and tricarboxylic acids by non-catalytic pyrolysis of such mixture or gases and vapors therefrom at a temperature of at least 700.degree. C. Such non-catalytic pyrolysis is more technically attractive than catalytic pyrolysis conducted at a temperature of from 300.degree. C. to 500.degree. C. which has a short activity life.

Abstract: Short, less than one second, residence time non-catalytic hydropyrolysis is conducted by rapid heating at more than 600.degree. C. per second of a solid mixture of aldehydo-, carboxy-, keto- and carboxy-, and aldehydo- and carboxy- substituted benzene and toluene and such solid also containing cobalt and/or manganese salts of organic acids and organic and/or inorganic bromides obtained from the manufacture of benzene di- and tricarboxylic acids up to a temperature of at least 700.degree. C. Such short residence hydropyrolysis produces attractive amounts of readily recoverable benzene and toluene as well as lower alkanes and alkenes and a solid carbonaceous char which can be burned to provide heat for the hydropyrolysis. The short residence hydropyrolysis is not subject to short activity and frequent periods of off-stream time as are the catalytic pyrolysis conducted at lower temperatures of from 300.degree. up to 500.degree. C.

Abstract: Solid residues obtained from the manufacture of benzene di- or tricarboxylic acid by the oxidation of di- or trimethyl substituted benzene with air in the presence of catalysis from a source of bromine in combination with one or both of cobalt and manganese when incinerated can produce bromine-containing particulates whose discharge into the atmosphere may be undesirable. The discharge of such bromine-containing particles into the atmosphere can be avoided by subjecting said solid residue in comminuted form or such form suspended in 30 to 50 weight percent water to continuous pyrolysis in the presence of an inert particulate solid in a zone heated to a temperature of at least 700.degree. C., contacting the gaseous product or a portion thereof after removal of benzene and toluene therefrom with a carbonate, hydroxide or oxide of one or both of calcium and magnesium and then incinerating the gaseous product or said portion thereof.

Abstract: A process for the isomerization of 1,5 and 1,6-dimethylnaphthalenes to a product including 2,6-dimethylnaphthalene which comprises passing a feed stream containing the 1,5 and 1,6 isomers over a catalyst at isomerization reaction conditions which catalyst consists essentially of from about 35 to about 45 weight per cent of the hydrogen form of mordenite dispersed in an alumina matrix.

Abstract: Fire resistant modified polyurethane foams are prepared from polyols and the monomeric products formed by the pre-reaction of polyarylpolyisocyanates and halogenated phthalic anhydrides at a temperature of about 210.degree. to 300.degree.C. wherein the weight ratio of the polyarylpolyisocyanate to be halogenated phthalic anhydride is from above 2:1 to 10:1 and wherein the amount of the imide incorporated into the polyarylpolyisocyanate varies from about 25 to about 75 percent.
