Abstract: Molten metal is poured into a casting space bounded by the cylindrical surfaces of two counter-rotating rolls (1,1') and two lateral retaining walls (3), and a thin solidified prod. is extracted from this space. A measured thrust is exerted on the retaining walls (3) parallel to the roll axes, in order to press them against the roll faces (11). The drag on each retaining wall in the direction of the casting motion is measured. The measured values of thrust and drag are used to derive a quantity which is indicative of the friction conditions in the contact zone between the retaining walls and cylinder faces. This quantity is compared with a predetermined value, and the comparison result is used for control of casting parameters. <IMAGE>

Abstract: A circuit for providing a phase con-trolled clock output (22) includes a ring os-cillator (34) having a delay line (38) for pro-viding an internal clock signal whose period varies with on-chip variations due to tempera-ture, voltage, and process. The circuit also in-cludes a clock phase select circuit (16) having a counter (24) and divider (26) for determin-ing the number of delays in one external clock period and an input for a phase select value. A delay line (18) having delay elements simi-lar to those of the ring oscillator (34) provides multiple delayed clock signals from the ref-erence clock signal. A multiplexor (32) hav-ing odd and even sides is used to select the desired clock signal in a glitchless manner. The phase controlled clock signal output (22) is controlled by the phase select signal and is compensated for on-chip variations due to temperature, voltage, and process.

Abstract: The production of excessive water in oil and gas wells and other subterranean formations is reduced by introducing a hydrocarbon fluid containing dispersed superabsorbing particles formed using invert emulsion polymerization techniques wherein the superabsorbing particles are formed from hydratable polymers which are cross-linked so that they are insoluble in water. By introducing these superabsorbing particles into fluid passages of the formation, the water producing zones can be selectively blocked off by allowing the superabsorbing particles to swell with the absorption of water within the aqueous fluid containing fluid passages, while the superabsorbing particles remain small and unswollen in the hydrocarbon conducting fluid passages. Thus, the ability of fluids to flow through the aqueous fluid containing fluid passages is selectively reduced resulting in the reduced production of aqueous fluids while maintaining production of hydrocarbons.

Abstract: A system for enhancing navigation or surveillance in low visibility conditions is realized by employing one or more ultraviolet radiation sources, a receiver which is capable of producing output signals from which a two dimensional image of the received radiation can be constructed, and a display device for displaying such image. In one preferred embodiment the ultraviolet radiation source is co-positioned with a critical marker such as a runway beacon or hazard beacon. The ultraviolet radiation emanates from the source, preferably modulated to form a repetitive, characteristic signal, propagates through the low visibility atmosphere, and received by the ultraviolet imaging receiver. In another preferred embodiment, an ultraviolet radiation source is placed at or near the ultraviolet imaging receiver, that is, onboard the same vehicle or at the same fixed location. One-or more reflectors are co-positioned with the critical markers. The reflector reflects or redirect an ultraviolet radiation signal, received from the source, back through the low visibility atmosphere to the ultraviolet imaging receiver whereby an image of the received radiation is presented to an operator by a display device. In another preferred embodiment, the reflector may be replaced with a transponder. The present invention permits a pilot, vehicle operator, air traffic controller, or other operator to perform navigation or surveillance tasks in low visibility conditions in similar manner to that employed under clear weather conditions.

Abstract: A system for coding of digital video images such as bi-directionally predicted video object planes (B-VOPs) (420), in particular, where the B-VOP and/or a reference image .(400,440) used to code the B-VOP is interlaced coded. For a B-VOP macroblock (420) which is co-sited with a field predicted macroblock of a future anchor picture (440), direct mode prediction is made by calculating four field motion vectors (MV f,toP, MV f,bot, MV b,top, MV b,bot) , then generating the prediction macroblock. The four field motion vectors and their reference fields are determined from (1) an offset term (MV D) of the current macroblock' s coding vector, (2) the two future anchor picture field motion vectors (MV top, MV bot), (3) the reference field (405,410) used by the two field motion vectors of the co-sited future anchor macroblock, and (4) the temporal spacing (TR b,top, TR b,bot, TR D,top. TR D,bot), in field periods, between the current B-VOP fields and the anchor fields. Additionally, a coding mode decision process for the current MB selects a forward, backward, or average field coding mode according to a minimum sum of absolute differences (SAD) error which is obtained over the top (430) and bottom (425) fields of the current MB (420).
