Inventor: BEER GARY L
IPC: C02F11/13
Filed: 1988-06-09
Abstract: Oily sludges containing volatile hydrocarbons are mixed with diatomaceous earth or perlite in a system which includes an indirect dryer (24) for vaporizing liquids have a boiling point of less than about 700°F. Dried solids are discharged from the dryer (24) and conveyed to an oxidation unit comprising a rotary kiln (40) or lift pipe combustor (42). Dried hydrocarbon free solids are recirculated for mixing with the oily sludge and condensable vapors are condensed and separated for further use or disposal. A system including the indirect dryer (24), condenser (54), oxidation unit, separators (56) for the condensate and separators (50) for gaseous products can be modified to receive hydrocarbon contaminated soils and other earth-like materials having particle sizes ranging from as low as 10 microns up to about 1.0 inches.

Abstract: A triaxial contact assembly for terminating a screened twisted pair of wires comprises three contact members (12,14,16) and a ferrule (18). The inner contact (12) is of conventional construction but the intermediate contact member (14) consists of an intermediate contact (20) to which are secured the inner insulator (34) and a spacer member (40). The outer insulator (54) is fixed to the outer contact (52). The number of separate componenets required to be assembled by the operator is thus reduced and assembly made quicker and easier.

Abstract: An output voltage, which is induced by a solid electrolyte in response to the concentration of oxygen included in exhaust gas from an engine, is compared with a reference voltage, the value of which is different in accordance with an air-fuel ratio reference set in advance for an air-fuel ratio control of the engine, whereby an air-fuel ratio of fuel mixture supplied to the engine is determined on the basis of a signal obtained by simply amplifying a deviation resulted from the comparison by a large amplification factor. Accordingly, the changing range of the signal with respect to air-fuel ratio is expanded remarkably so that the measurement accuracy of an air-fuel ratio sensor is much improved.

Abstract: A pressure diffuser (10) for paper pulp includes a vertical pressurizable liquid-tight vessel (11) having a pulp inlet (12) at the bottom and a pulp outlet (13) at the top. One or more ring shaped screen elements (15), providing first and second concentric screen surfaces (16), are vertically mounted within the vessel. A number of radially extending header arms (18) mount the screen elements for movement in the vessel and in fluid communication with it. A first linear actuator (37) effects reciprocation of the arms. A cylinder (35), open at both ends, is affixed to the arms and extends both above and below them, and a piston (39) is disposed within the cylinder, below the arms. A second linear actuator (40) is operatively connected to the piston to effect reciprocation of the piston in the cylinder. A guiding conduit (46) surrounds the open end of the cylinder above the arms and guides reciprocation of the cylinder and transports liquid from the arms to an effluent outlet. A perforated jacket (57) surrounding the guiding conduit, nozzles (61) at the vessel wall, and the like introduce liquid into the vessel for treatment of the pulp. The ring shaped screen element is connected to the arms in a manner to allow the best liquid communication between them. In this way pulp can be effectively treated in a pressurized vessel while the screens for treating the pulp are periodically backflushed without causing a surge within the vessel.

Abstract: The fuel rod (2) comprises a cladding tube (6), the outside diameter (da) of which is preferably da = 9.36 mm or da = 10.53 mm. The inside diameter (di) is preferably di = 8.22 mm or di = 9.30 mm. In the cladding tube (6), a number of cylindrical pellets (8) is accommodated, the diameter (D) of which is preferably D = 8.05 mm or 9.11 mm. The centre-to-centre spacing (p) from fuel rod (2) to fuel rod (2) is predetermined in the fuel assembly and is p = 12.7 mm or p = 14.3 mm, respectively. These values, which are conventional apart from the outside diameter (da), ensure that the ratio P/da is within the range from 1.35 to 1.37 whereas the wall thickness ((da-di)/2) is reduced compared with conventional fuel assemblies. This measure ensures that the thermohydraulics and the neutron economy are improved without additional pellet diameters (D) deviating from the previous standard having to be manufactured.

Abstract: An instruction decoder for a pipelined data processing unit simultaneously decodes two source specifiers and one destination specifier. All three of the specifiers can be register specifiers in which the specified operand is the content of a specified register. Any one of the specifiers can be a complex specifier designating an index register, a base register, and a displacement. Any one of the source specifiers can specify short literal data. Data for locating the two source operands and the destination operand are transmitted over parallel buses to an execution unit, so that most instructions are executed at a rate of one instruction per clock cycle. The complex specifier can have a variable length determined by its data type as well as its addressing mode. In particular, the complex specifier may specify a long length of extended immediate data that is received through the instruction buffer over a number of clock cycles.

Abstract: An aromatic hydrocarbon is chloroethylated to a 1-­chloro-1-arylethane with minimal co-formation of diaryl­alkane by-product by reacting it with hydrogen chloride and acetaldehyde at a temperature in the range of -10°C to -35°C in the presence of at least about 1.4 mols of hydro­gen sulfate per mol of the aromatic hydrocarbon and in the absence of more than about 15% by weight of water, based on the weight of the hydrogen sulfate. The process is of particular advantage in the chloroethylation of the less reactive aromatic hydrocarbons, such as isobutylbenzene and other monoalkylaromatic hydrocarbons, which have previously yielded an undesirable amount of diarylalkane when chloroethylated with acetaldehyde.

Abstract: A display monitor for monitoring data flowing on the avionics data buses of an aircraft is disclosed. The monitor includes an interface card (53) for interfacing a programmed personal computer (PC) (51) to avionics buses (31, 33, 35, 37, 39) and a set of discrete input/output lines (63). The interface card (53) includes a series of ARINC receiver/transmitters (65, 67, 69, 71), a programmed central processing unit (CPU) (55), a primary memory (e.g., a RAM) (59) and a dual port input/output (I/O) memory (61). The ARINC transmitter/receivers (65, 67, 69, 71) provide communication paths to the avionics data buses (31, 33, 35, 37, 39) and the dual port I/O memory (61) provides a communication path to the PC data bus (75). The interface card CPU (55) continuously scans the ARINC receiver/transmitters (65, 67, 69, 71) looking for avionics data and, at greater intervals, the discrete input lines (63) and the dual port I/O memory (61) looking for commands. ARINC data is initially "dumped" into the card primary memory (59) and later transferred to the dual port shared memory (61) from whence it is transferred to a work buffer in the PC. As it occurs, new data is written over old data. The high/low state of the discrete lines are used to control the setting of flags in the dual port shared memory (61). The PC (51) continuously scans the dual port shared memory (61) and the PC keyboard (52). In response to either discrete flags or PC keyboard commands, the PC shifts data in the work buffer to more permanent storage and/or prints selected data stored in the work buffer. The PC keyboard is also used to create commands that switch the monitor from a strictly monitoring mode of operation to an autotest/monitoring mode of operation. When in the autotest/monitoring mode of operation, key push buses are decoupled from avionics equipment and the PC is used to create commands similar to those produced by the decoupled key push sources. The data resulting from the commands is handled in the same way similar data is handled in the strictly monitoring mode of operation.
