Patent EP-0402019-A2 (EP)
Inventor: JONES EDWARD M JR
IPC: B01J8/22
Filed: 1990-05-25
Abstract: A method and apparatus is provided for removing catalyst (109) from a distillation column reactor (100) and replacing the catalyst with fresh or regenerated catalyst. More specifically a small particulate catalyst is supported by wire mesh or screen or filter medium on trays (101,103) in a conventional distillation column and substantially submerged by the liquid on the trays. The vapor rising through the liquid tends to keep the catalyst in suspension in the liquid. A draw-off (111) is provided for each tray having catalyst supported thereon whereby liquid containing the suspended or slurried catalyst can be removed to a separator (200) during operation. The catalyst is separated, as in a settling tank separator, from the liquid recycled to the tray until all the catalyst has been removed. The separated catalyst is removed for either regeneration or discarding. Fresh catalyst can then be added to the separator where it is slurried into the liquid again being recirculated from the tray. The trays can all be connected to the same separator/slurry mixer by the appropriate piping and manifolds.

Abstract: An amplification procedure is performed on a first sample in which one or more of the four normal ribonucleoside triphosphates(rNTPs) or deoxyribonucleoside triphosphates (dNTPs) is replaced with an exo-sample nucleotide that is not present in nucleic acid to be amplified. After amplification, any contaminating amplified product that may be remaining is subjected to a physical, chemical, enzymatic, or biological treatment which renders nucleic acid containing the exo-sample nucleotide substantially unamplifiable. The treatment may be done as a separate step or it may be done in the presence of a second sample containing nucleic acid sequences to be amplified. The amplified nucleic acid sequences derived from the first sample which contaminate the second sample are not further substantially amplified during amplification of nucleic acid sequences of the second sample.

Abstract: A logic controlled gate is inserted in the arbitration logic of a computer system that supports multiple masters on a data bus. In such a system with arbitration for data bus ownership, the gate is so controlled that competitors for the data bus cannot force the main processor (CPU) from the data bus until certain system conditions are met. In particular, a pattern of CPU "hits" to memory cache is recognized as an opportunity for the CPU to relinquish the data bus.

Abstract: A method used in a computer system for managing attribute data for subobjects of a class of data objects. When a data object is created, a set of default attributes are stored in internal memory in association with the data object for all instances of subobjects of the data object. A set of attributes for overriding the default attributes are stored in internal memory for each instance of a subobject. When a query or system response is required which requires knowledge of the attributes for an instance of a subobject, these final attributes are formed by fetching the default attributes associated with the data object and by overwriting the default attributes with the overriding attributes, if any, associated with the instance of the subobject. In a preferred embodiment, the invention is used in a computer windowing system in which windows are associated with data objects called widgets or gadgets and subobjects of the data objects are associated with items which are displayed within an associated window.

Abstract: An apparatus for measuring the distance of a target includes a circuit arrangement of a transmitting circuit, a first receiving circuit, a second receiving circuit, a charging/discharging circuit, a switching gate, an analog-to-digital converter, a microprocessor, and a monitor. A modulated pulse signal is emitted by the transmitting circuit, and will be received by the first receiving circuit which makes the charging/discharging circuit start being charged. When the modulated pulse signal is reflected from a reflective object, it will be received by the second receiving circuit and the second receiving circuit will send a stop signal to terminate the charge to the capacitor of the charging/discharging circuit. By calculating the time period of the charging time under the control of switching gate, analog-to-digital converter, microprocessor, the distance of a target object is measured. Further, the modulated pulse signal received by second receiving circuit will be received by the microprocessor so as to determine whether the infrared ray received is the originally emitted modulated signal by transmitting circuit.

Abstract: A method for a phase-locked loop, which circuit includes, in a preferred embodiment, a resistor to unbalance phase detector outputs to an operational amplifier to cause the voltage output of the operational amplifier to sweep and thus cause the frequency output of a voltage controlled oscillator to sweep. Simple circuity detects correct lock and terminates sweeping; or, if lock is not achieved, causes the output of the operational amplifier to remain at a low level until the operational amplifier is reset and then permits resweep. Very little auxiliary circuitry is required.

The chopper 20 includes an inductor 22 and a switching element 21 which is connected in series with the inductor 22 across the rectifier 10 and is driven to periodically turn on and off so as to store into the inductor 22 an energy from the rectified DC voltage when the switching element 21 is turned on and to release the energy from the inductor through a blocking diode 23 to a charge-pump circuit 50 when the switching element 21 is turned off. The charge-pump circuit 50 receives the energy released from the inductor 22 as well as from the rectifier 10 to accumulate a first voltage and provides a divided voltage of the first voltage to charge a smoothing capacitor 60 by the divided voltage so as to develop thereat the step-down output DC voltage for driving a load. The converter further includes a switch 61 which is turned on during at least a portion of an ON-period of the switching element 21 in order to connect the smoothing capacitor 60 to the charge-pump circuit 50 for charging the smoothing capacitor 60 by the divided voltage. The switch 61 is turned off during an OFF-period of the switching element 21 in order to disconnect the smoothing capacitor 60 from the chopper 20.
