Abstract: The polymerization of certain alpha-olefins in a gas phase involves the problem of agglomeration of the product into particles disadvantageous from the viewpoint of its handling.      In the present invention this problem has been solved by means of a new type of process for the homo- or copolymerization of alpha-olefins. In the process the catalyst system is pretreated by contacting and reacting a transition-metal compound which is solid or on a solid carrier with an organoaluminum compound, and possibly an electron donor, in a liquid medium, and by drying the thus formed reaction product to produce a solid catalyst system. The thus pretreated solid and active catalyst system is then fed together with an alpha-olefin in the gaseous state into a gas-phase reactor, and polymerization is carried out by contacting them with each other. By feeding a dry and active catalyst system into the gas-phase reactor, it is possible to avoid the agglomeration of the product which occurs in conventional processes in which an organoaluminum compound and possibly an electron donor are fed in a liquid medium into the reactor.

Abstract: Autofocus apparatus for use in an optical system utilizing a recording medium formed from a birefringent medium and a radiation-sensitive medium. The autofocus apparatus automatically focuses radiation through the birefringent medium and substantially at the interface between the birefringent medium and the radiation-sensitive medium and includes a source of linearly polarized radiation, a quarter-wave plate to convert the linearly polarized radiation to circularly polarized radiation, and an actuator controlled lens for focusing the radiation onto the recording medium, whereby radiation reflected from the first surface of the birefringent medium and the interface between the birefringent medium and the radiation-sensitive medium passes back through the lens and quarter-wave plate and is deflected by a beamsplitter to a polarization detector.  The polarization detector isolates polarization components which arise from reflection at the interface and the isolated polarization components impinge upon a detector.  The detector provides a focus-error signal which is applied, in turn, to the actuator to maintain focus.

Title: Direct smelting process
Inventor: SATO RYODA
IPC: C22B34/34
Filed: 1990-01-23
Granted: 1996-03-05
Abstract: The present invention relates to a process for directly smelting ores, metal oxides or the like with a thermal plasma.         The direct smelting process of the invention can be practiced easily by simple equipment regardless of the form of the material to be smelted without using any plasma forming gas.         The present process is characterized in that a polyphase current voltage is applied to a multiplicity of graphite electrodes to cause arc discharge in air and produce a strongly reducing nontransferred plasma arc due to the resulting oxidation decomposition of the graphite electrodes.  The plasma arc is jetted out from the tips of the electrodes directly against the material to be smelted.

Title: Dielectric resonator support system for a waveguide
Inventor: LEVINSON DAVID S
IPC: H01P1/208
Filed: 1990-12-31
Granted: 1995-01-31
Abstract: A system for supporting a dielectric resonator in a circular waveguide. A dielectric resonator is held in its optimum position using support posts or rods. The support rods are made from a suitable dielectric material, and slip fitted in holes provided at 90° intervals around the periphery of the dielectric resonator. The support rods are affixed to the waveguide, by gluing or being screwed in place. The support rods are slip fitted such that they are allowed to expand, due to temperature, without causing stress on the dielectric resonator, thus the dielectric resonator is held in position without being affixed to its supporting structure. This is an inexpensive and simple solution to a complex problem. The support system is self-centering and free from all stress. The support system utilizes a minimum amount of supporting material which permits realization of the best unloaded Q.
