A method and system for controlling drilling mud density in drilling operations. The mud required at the wellhead is combined with a base fluid of a different density to produce diluted mud in the riser. By combining the appropriate quantities of drilling mud with base fluid, riser mud density at or near the density of seawater may be achieved, thereby permitting greater control over the pressure in the wellbore and various risers. Blowout preventers may also be used in combination with the process to control these pressures. Concentric risers are disclosed, wherein an annulus defined within one riser is utilized to carry the different density base fluid to the injection point for injection into the drilling mud, while an annulus defined within another riser is utilized to carry the combination fluid and cuttings back to the drilling rig. Cuttings are separated in the usual manner at the surface. The diluted mud is passed through a centrifuge system to separate drilling mud from the different density base fluid. The centrifuge system may also be utilized to separate the recovered drilling fluid into a substantially barite portion and a substantially drilling fluid portion, wherein the two portions are stored locally at the rig and recirculated during drilling operations.

A novel apparatus for and method of delay alignment between amplitude and phase/frequency modulation paths in a digital polar transmitter. The invention provides a fully digital delay alignment mechanism where better than nanosecond alignment is achieved by accounting for processing delays in the digital circuit modules of the transmitter and by the use of programmable delay elements spread across several clock domains. Tapped delay lines compensate for propagation and settling delays in analog elements such as the DCO, dividers, quad switch, buffers, level shifters and digital pre-power amplifier (DPA). A signal correlative mechanism is provided whereby data from the amplitude and phase/frequency modulation paths to be matched is first interpolated and then cross-correlated to achieve accuracy better than the clock domain of comparison. Within the ADPLL portion of the transmitter, precise alignment of reference and direct point injection points in the ADPLL is provded using multiple clock domains, tapped delay lines and clock adjustment circuits.

A hollow light-recycling backlight has a “semi-specular” component providing a balance of specularly and diffusely reflected light improving the uniformity of the light output. The component may be arranged on the reflectors (1021), (1014) or inside the cavity (1016). This balance is achieved by designing the component's “transport ratio” defined by (F−B)/(F+B), (F and B are the amounts of incident light scattered forwards and backwards respectively by the component in the plane of the cavity) to lie in a certain range. Furthermore, the product of the front and back reflector “hemispherical” reflectivities should also lie in a given range. Alternatively, the “cavity transport value”, a measure of how well the cavity can spread injected light from the injection point to distant points in the cavity should lie in a further range and the “hemispherical” reflectivity of the back reflector should be >0.7.

An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration. Location of the distributor at a standpipe junction will also typically allow the placement of the distributor at a lower location in the process which eliminates the need to add vessel height for supplying pressure drop for the particle discharge point. The distributor arrangement also fits compactly into most common standpipe junctions. Thus, the arrangement of this invention solves the problem of inserting an extended array of feed injection points into a fluidized particle contacting process without providing a large amount of clearance or additional vessel height.

A method for measuring a stability margin at a node of a polyphase power grid injects suppressed-carrier stimulus into a node of the power grid by low-level amplitude modulation of the output voltage of a pre-exiting generator connected to the node. Response signals are obtained and product demodulated on a per-phase basis and summed in three-phase groups. Demodulated and summed responses contain signals that represent the suppressed-carrier impedance upstream and downstream of the stimulus injection point, and are processed to determine the stability margin at the node.
