Abstract: This invention is related to the measurement of flow rates and component fractions of individual phases of a composite fluid. More particularly, the invention is directed toward apparatus and methods for determining the volumetric flow rate or mass flow of one or more phases of a fluid by measuring the activity of one or more specific radioactive isotopes affected by a specific phase of the flowing fluid stream. Phase isotopes are deposited upon one or more inserts, and the inserts are positioned within the multiphase fluid flow. Each phase isotope is soluble in only one phase of the multi-phase flow. The rate at which each phase isotope is washed from an insert by each specific fluid phase is then measured by detecting the rate of decrease of preferably photon activity from an insert. Phase flow parameters, including volumetric flow rate and mass flow rate, are then determined for each fluid phase from the measured rate at witch the corresponding phase isotope is washed from an insert.

Abstract: An adjunct processor for a wireless telephone system utilizes object-oriented software for providing a common air-interface protocol for each cell site's base station, so that, regardless of the specific cellular system, it may be coupled to the central, adjunct node-processor of the invention, so that multifarious-operating cellular systems may be linked by the central personal computer adjunct node-processor into one holistic system comprised of many different cellular operating systems and of many node-processors. A network of many adjunct node-processors allows hand-off between adjunct processors, so that if one adjunct processor fails or is down, another adjunct processor in the network may take over its functions. Each adjunct processor also has an alarm-management system, which may take over the alarm-management operation of a down adjunct processor.

Abstract: The invention provides an apparatus for optimizing performance of a fluid pump having a supply port and a pressurized output port, comprising: a pressurized supply of a first fluid; a variable regulator coupled to the supply having a variable pressure output; and a second pump driven by the variable pressure output for impelling a second fluid into the supply port of the fluid pump.

Abstract: This invention is related to the measurement of flow rates and component fractions of individual phases of a composite fluid. More particularly, the invention is directed toward apparatus and methods for determining the volumetric flow rate or mass flow of one or more phases of a fluid by measuring the activity, as a function of time, of one or more specific radioactive isotopes affected by a specific phase of the flowing fluid stream. Radioactive phase isotope material is deposited upon one or more inserts, and each deposition of phase isotope material is coated with a corresponding phase coating. Each phase isotope and corresponding phase coating is soluble in only one phase of the multi-phase flow. The inserts are then inserted into the multi-phase flow, and the time required for each flow phase to wash the corresponding phase coating from the insert is measured by the release of the corresponding phase isotope into the flow stream.

Abstract: A plunger mechanism is disclosed comprising: a plunger slidable in a generally cylindrical body between an extended position and a retracted position. A bush receives the body for relative rotation about the axis. The body and the bush are formed with co-operating means allowing the body to slide axially when the body is in one rotational position relative to the bush and to be locked axially when the body is in another rotational position relative to the bush. A stop member is slidable in the body and biassed in one direction. The stop member is formed with a lug projecting through a slot in the body and into a slot in the bush. The plunger is provided with means for engaging the stop member to slide it in the body against the bias. The slots in the body and in the bush each have a narrow section in which the lug locates when the stop member is in a first position in the direction in which it is biassed.

Abstract: An apparatus for washing and recovering a contaminant from an object. A washing agent flows over the object, and the washing agent and contaminant are received in a basin. A slurry of the washing agent and contaminant are circulated through at least one separator and one filter to produce a cleaned slurry flow. The cleaned slurry flow is recirculated into the basin. A first pump which is used to flow the washing agent over the object has a supply port and a pressurized output port. A pressurized fluid supply is coupled to a variable regulator with a variable pressure output. A second pump driven by the variable pressure output impels the washing agent into the supply port of the first pump.

Abstract: A method of producing an RNA fingerprint of a poly(A).sup.+ RNA preparation. At least one oligonucleotide primer and a supply of nucleotides of which one is a terminator nucleotide, are added to the poly(A).sup.+ RNA preparation or a single-stranded cDNA preparation derived from it. cDNA products are synthesized from the RNA, or DNA products from the cDNA and the products are separated to produce an RNA fingerprint.

Abstract: Novel enzyme mutants are disclosed which are derived from a precursor enzyme by replacing or modifying at least one catalytic functional group of an amino acid residue in a precursor enzyme. Such mutant enzymes have a catalytic preference for substrates which provide the replaced or modified catalytic group or its equivalent such that the substrate together with the enzyme mutant assists in its own catalysis.

Abstract: A safety system associated with an engine of a marine vessel wherein the safety system includes a blower, a control unit, and a plurality of sensors. An intake pressure detection device is coupled to the intake manifold of the engine for the detection of pressure at the intake manifold. A sensor is coupled to the engine to monitor oil pressure and, along with the intake pressure detection device, transmits a signal to the control unit, with the signals each having a characteristic corresponding to the respective engine pressure. Detection of an engine pressure associated with engine idling or low cruise operation causes the control unit to activate the blower. The safety system includes interactive heat sensors and vapor sensors to monitor the atmosphere in an engine compartment. Detection of a volatile environment activates the blower and triggers both an audio and a visual warning.
