Patent number: 4610574Abstract: An apparatus is provided for introducing a mixture of dry catalyst and a hydrocarbon liquid into a polymerization reactor vessel. The apparatus comprises a enclosed mixing tank with rotating mixing blades and a rotatable shot valve spaced below the mixing tank. The shot valve can be rotated from a first position in communication with an opening in the lower portion of the mixing tank to a second position in communication with a hydrocarbon feed conduit that provides hydrocarbon liquid to the polymerization reactor vessel. A bypass conduit is provided for introducing hydrocarbon liquid from the hydrocarbon feed conduit into the mixing tank wherein the interior of the mixing tank is maintained at the same pressure as the hydrocarbon feed conduit.Type: GrantFiled: January 17, 1985Date of Patent: September 9, 1986Assignee: Amoco CorporationInventor: Edwin F.

Patent number: 4206415Abstract: An audio signal amplitude detector for applying stereo audio signals above a predetermined amplitude to at least one pair of speakers. The audio signal for each channel is amplified and compared with two reference voltages. When the amplified audio signal is below a lower one of the reference voltages, the signal is blocked to the connected speaker amplifier. As the amplitude of the audio signal increases between the first and second reference voltages, an increasing portion of the audio signal is applied to the connected speaker amplifier until a maximum signal is applied when the amplitude is above the second reference voltage.Type: GrantFiled: July 31, 1978Date of Patent: June 3, 1980Assignee: Eprad IncorporatedInventors: Angelo Boudouris, Edwin F.
