Title: Multi-panel distribution board with a bus bar system
Inventor: BRAUN BODO
IPC: H02B1/20
Filed: 1991-02-12
Abstract: Abstract An electrical distribution board incorporates a plurality of assembled panels and bus bars that extend across these panels.          The supporting elements for the distribution board (side walls 1, 2, 10, 11) incorporate a locally set back or restricted profile (profile notches 3, 4, 12, 13), thereby forming a bus-bar space that is accessible along its whole length.  Bus-bar carriers (40) are formed to be comb-like and have notches for the full profile of the bus bars (43).  The arrangement makes it possible to lay the bus bars in the bus-bar space without using the push-through method of installation that was formerly used and which began at one end of the  distribution board.  The new arrangement is equally well suited for low-voltage distribution boards with bus-bar spaces at the top or at the back.

Filed: 1991-04-18
Abstract: METHOD OF OPERATING AN UNSATURATED GAS PLANT                            ABSTRACT      A method is disclosed for operating a refinery gas plant such as the unsaturated gas plant (USGP) of a catalytic hydrocarbon conversion process that results in a reduction of the corrosive effect of acid gases on the gas plant vessels and equipment.  The method comprises contacting acidic hydrocarbon feedstreams to an unsaturated gas plant separator zone with lean acid gas absorbing absorbent in an absorbtion zone comprising at least one liquid absorber bed and one vapor absorber bed.  The liquid and vapor absorber beds are located upstream of the separator zone. The feedstreams to the gas plant comprise unstabilized, or wild, liquid gasoline and liquid and vapor output streams from the liquid-vapor separator for inter stage wet gas compressor of the conversion process main fractionator.  Accordingly, these feed streams are deacidified before separation in the USGP deethanizer-absorber, sponge absorber, and debutanizer. This also eliminates the need for deacidification of the gas plant product stream.

Title: Apparatus and method for controlling the air/fuel ratio of an internal combustion engine
Inventor: EARLESON WALTER E
IPC: F02D41/14
Filed: 1990-02-20
Abstract: Abstract of the Invention Apparatus And Method For Controlling The Air/Fuel Ratio Of An Internal Combustion Engine In the subject invention an electronic control unit 12 is used to control the air/fuel ratio in an engine combustion chamber (46) in response to sensed engine parameters.  More particularly, a magneto interface (106) produces an ignition signal which is delivered to a spark plug (110).  The spark plug (110) is disposed essentially in the center of a combustion chamber, and it ignites an air/fuel mixture in the chamber in response to the ignition signal.  A sensor (126) such as an ion probe, for example, is further disposed in the combustion chamber (46) longitudinally from the spark plug.  The sensor (126 produces an ionization signal in response to a flame front propagating past the sensor (126).  A buffer circuit (112) receives the ignition and ionization signals and produces a combustion signal in response to a time difference between the reception of these signals.  The electronic control unit 12 receives the combustion signal and calculates a combustion signal air/fuel ratio in response to the combustion signal. Both the combustion signal and the combustion signal air/fuel ratio are responsive to changes in the quality of the fuel in the combustion chamber. Subsequently, the control unit 12 calculates a volumetric air/fuel ratio.  The volumetric air/fuel ratio is indicative of the volume of air and fuel in the combustion chamber (46), and it does not account for fluctuations in fuel quality.  Finally, a wastegate (56) is controlled in response to the volumetric and combustion signal air/fuel ratios.

Title: Procedure in order to detect the gas potential in sedimentary basins and the oil potential obtained from this
Inventor: KETTEL DIRK
IPC: G01V9/00
Filed: 1991-07-02
Abstract: Dr. Dirk Kettel Summary Procedure in order to detect the gas potential in sedimentary basins and the oil potential obtained from this Gaseous hydrocarbons, thermocatalytically generated by gas- or oil-prone sourcerocks in subsiding sedimentary basins or penetrating the seal of gas or oil accumulations at the subsurface, reach the surface in geologically short times in low concentrations. The transported hydrocarbon gases transmit information to the surface concerning hydrocarbon potential, organic facies and maturity of the generating sourcerock or concerning the gas characteristics of an accumulation. These facts are used by the method presented here in order to determine the prospectivity of the subsurface by means of near-surface measurements. The gaseous traces are analyzed according to their molecular and isotopic composition, and from there the status of gas and oil generation is derived by consideration of compositional shifts due to migration. The shifts in isotopic composition of methane during migration are quantified. Relationships of the original gas parameters reconstructed in this way to the geological status and potential of their source - which means to the prospectivity of the basin - are established. Herewith, the hydrocarbon potential available to the filling of a discrete structure, or regionally to a sedimentary basin, and its lateral variations could be assessed before drilling. Under special conditions, hydrocarbon accumulations in the subsurface could directly be detected, as well as lateral variations in the effectivity of seals. This is the reason why application of the method presented here can effectively reduce risk in exploration for ail and gas.

Abstract: 2053897 9015451 PCTABScor01 A microstrip capacitively-compensated directional coupler (100) with improved directivity and decreased coupling length. The directional coupler (100) of the invention includes a primary transmission line (102), having a first port (126) and a second port (128) and a secondary transmission line (104) electromagnetically coupled to the first line. The secondary transmission line has a third port (130) and a fourth port (132). The invention also calls for a first reactive coupling network (138) disposed between the first port (126)  and the third port (130), and a second reactive coupling network (140), disposed between the second port (128) and the fourth port (132). Those reactive couplings improve the directivity of the coupler (100) and foreshorten its coupling length. The invention also calls for a phase-shifting line (210) for shifting the phase of the coupled signal. The phase-shifting line (210) further foreshortens the required coupling length for the coupler.
