    摘要： A process is provided that produces polyolefins. The process comprises mixing a first stream, which comprises at least one catalyst deactivating agent, with a second stream, which comprises at least one polyolefin, at least one catalyst, at least one diluent, and at least one monomer, to produce a third stream, which comprises at least one polyolefin, at least one deactivated catalyst, at least one diluent, and at least one monomer. By utilizing the deactivating agent, polymerization can be slowed, or substantially stopped, when downstream equipment is being repaired or process control problems are being corrected. Later, polymerization can be restarted without the use of scavengers to remove poisons from the slurry polymerization reactor, and polyolefin production can be resumed.

    摘要： A method and apparatus are provided for producing a product comprising a nitride compound, such as for example silicon nitride. A reactor is provided which has a chamber defined therein which is divided into a combustion zone and a reaction zone. A combustible mixture is injected into the combustion zone in a direction generally toward the reaction zone, and is accordingly combusted in the combustion zone. At least one reactant is injected at the boundary between the zones into the reactor chamber in a direction generally parallel to the longitudinal axis of the chamber so as to react to form raw product comprising the nitride compound. According to another aspect, a raw product powder as produced by the reactor comprises silicon nitride as the nitride compound and further comprises elemental silicon.

    摘要： In a static inverter for providing a low-frequency output (e.g. 60 Hz) from a d.c. supply, the passage of low-frequency currents through the inverter transformer is avoided by producing a train of high-frequency pulses (e.g. 40 kHz) which represent, for example by their pulse widths, the successive instantaneous amplitudes of the required low-frequency voltage. These pulses cause a train of corresponding pulses to be produced at the secondary of the transformer, and this train is filtered to produce a unidirectional voltage having the desired instantaneous amplitudes. This voltage is fed to a transistor switching bridge which changes the unidirectional voltage into an alternating voltage having the required low frequency. A circuit is preferably provided to allow regeneration of power from the load back into the d.c. supply.
