Abstract: A continuous process for converting benzene or a derivative thereof to phenol or a derivative thereof comprises continuously activating .alpha.-sites on a zeolite catalyst by contacting the catalyst with a free oxidant activator, thereby producing an activated zeolite hydroxylation catalyst, and separately and continuously contacting benzene or a derivative thereof with the activated zeolite catalyst, thereby producing phenol or a derivative thereof.

Abstract: A mounting plate includes a plurality of support cylinders mounted orthogonally to the mounting plate, wherein each support cylinder is arranged to receive a baseball at its upper end. Each cylinder is of a tubular construction to accommodate the baseball sphere and each cylinder including a coil spring mounted therewithin, with each coil spring including a plurality of spring rods fixedly mounted to adjacent coils of the spring. One of the spring rods is arranged for receiving a hook member, a lower distal end of the hook member secured to a suction cup. The suction cup is initially adhered to the mounting plate within the lower distal end of the cylinder, and each suction cup of each support cylinder arranged for randomly releasing the spring to project the spring upwardly to project the associated baseball from the support cylinder with an axial of an individual attempting to strike.

Abstract: This invention relates to the treatment of carbon-containing materials. In one aspect this invention relates to the treatment of carbon-containing materials, such as coal, coke and hydrocarbons to produce oxides of carbon therefrom. In still another aspect, this invention relates to a process for the production of high purity synthesis gas, a mixture of hydrogen and carbon monoxide, from carbon-containing materials. More specifically, this invention relates to inorganic metal-oxygen containing materials useful as the oxidant, oxygen carrier and supplier, and heat transfer agent for the endothermic oxidative gasification of carbon-containing materials.

Abstract: Carbon-containing materials are gasified to produce high purity carbon monoxide in a three zone unified system (oxidizer, reducer and gasifier) using a metal oxide as the oxygen and heat source for the gasification with carbon monoxide. Carbon monoxide contacts the metal oxide prior to the gasification to release the oxygen and convert the carbon monoxide to carbon dioxide as the gasification medium.

Abstract: The acquisition means includes a voltage controlled oscillator, comparison means for comparing an input signal to a signal from the voltage controlled oscillator, filtering means and a summing network connected in a phase-locked loop and providing an output signal at an output thereof at the input of said summing network, a signal multiplying network connected to receive the input signal and a signal from the VCO of the phase-locked loop and providing an output signal approximately 90 degrees out of phase with the output signal of the phase locked loop and two all pass networks connecting the output signals from the multiplying network and the phase locked loop to two inputs of a multiplier which has an output connected to the summing network, the all pass networks being designed to shift the phases of the signals so that they are in phase when applied to the multiplier.

Abstract: An S-band radio frequency subsystem including two transmitters, two receivers and two antennas and capable of connecting either transmitter or receiver to either antenna while permitting simultaneous operation of a transmitter and a receiver. Circulator switches provide selection of a specific transmitter and receiver for connection to either a high gain or low gain antenna. Transmitter output filters, receiver input filters, and diplexers are combined to prevent radiation or coupling of unwanted transmitter and receiver signals and to provide isolation, permitting simultaneous operation of the transmitter and receiver. The filter elements are designed of constant diameter coaxial elements to meet demanding rejection, loss, power-handling and environmental characteristics.
