Patent EP-0065364-A1 (EP)
Inventor: LAKE IVAN JAMES SAMUEL
IPC: C07C5/27
Filed: 1982-04-26
Abstract: A hydrocarbon conversion process comprises contacting a feed of an alkylbenzene or a mixture of alkylbenzenes under isomerisation conditions in the vapour liquid phase with a catalyst comprising zeolite NU-4. The feed is preferably a xylene or a mixture of xylenes, optionally containing up to 25% by weight ethylbenzene. Compared with a conventional amorphous silica-alumina catalyst for xylenes isomerisation, the zeolite NU-4 catalyst produces more para-xylene, destroys a much higher proportion of ethylbenzene (where present) and destroys less of the xylenes.

Abstract: A device for measuring density and moisture of a material includes a hollow roller (14) rotatably mounted on a shaft (16) for rolling movement on the surface of the material. A radioactive source and density and moisture detectors are supported below the shaft (16) and adjacent to the inner surface of the roller (14) at substantially a fixed distance from the surface of the material being measured as the roller (14) is rolled. The detectors are coupled to a conventional counter and microprocessor circuitry which provide an output reading related to the density or moisture content of the material. The shaft (16) may be mounted for tilting movement so that the roller (14) may pitch in conformity to contours in the material surface.

Abstract: Apparatus for generating and detecting magnetic field components oscillating at a radio frequency in a direction transverse to a static magnetic field in a nuclear-magnetic-resonance (NMR) system. The apparatus has a plurality of conductive elements spaced from one another and from the axis along which the static magnetic field is directed. The relative amplitudes of alternating currents in the conductive elements are controlled to generate a spatially uniform field. A preferred embodiment uses a standing wave in a coil assembly to control relative current amplitudes, which takes advantage of the current-phase characteristics of such waves. Detection of RF magnetic fields results from an EMF generated in the coil assembly in response to the time-varying magnetic field; the high Q of the coil assembly enhances detection properties.

Abstract: In order to protect converter equipment which includes GTO switching-off thyristors and having d-c inputs and a protective inductance connected in series therewith against short circuit currents, a short circuit path for d-c current flowing from a d-c supply source on the one hand, and on the other hand, an energy storage device, is inserted into the d-c circuit, closed via an auxiliary thyristor, of the converter equipment in such a manner that through the change of the state of storage of the energy storage device, a countervoltage is impressed on the d-c terminals, which leads to the forcible commutation of the switching-off thyristors. The energy storage device advantageously comprises an auxiliary winding of a limiting choke serving as a protective inductance. The fault current, which increases steeply in the event of a short circuit via the protective inductance and the auxiliary thyristor, causes, due to the magnetic coupling, the generation of a counter voltage in the supplemental winding required for forcible commutation of the switching-off thyristors. For monitoring the current and for generating the auxiliary thyristor firing energy, a monitor likewise fed inductively by means of the protective inductance may be provided.
