Abstract: A multi-purpose drilling rig has a movable pipe support cradle which moves horizontally to transfer drill pipe from a storage area to the well being drilled, and vice versa. The cradle travels along a roof platform supported by load-bearing hydraulic lifting rams. Raising or lowering the lifting rams raises or lowers the roof platform, along with the drill pipe suspended from the cradle. Structural towers stabilize the lifting rams against buckling and lateral loads. Supplementary lifting capacity is provided cradle-mounted roof rams having pistons which may extend downward from the cradle, with the drill pipe suspended from a yoke interconnecting the roof ram pistons. For offshore drilling, a control system senses fluctuations in rig elevation due to wave action, and automatically adjusts extends or retracts the rams as required to maintain constant load on the drill bit. Also disclosed is a method of drilling which utilizes vertical and lateral movement of the cradle and top drive.

Abstract: An analytical test device is described for the immunochromatographic determination of the presence of one or more analytes in fluid samples. The device is configured such that the sample is allowed to enter the detection zone simultaneously from many different directions, eliminating stagnation of the flow of the sample. By selection of the porous substrate, the device also allows for the separation of red blood cells from plasma, providing a rapid test for one or more analytes in a sample of whole blood. The device of the present invention may measure more than one analyte simultaneously from a single sample, either by having multiple immunochromatographic pathways fed by a single sample, or multiple analytes detected in the same pathway by way of multiple capture antibodies.

Abstract: A method is described for determining recirculation of blood in a vascular access of a patient undergoing dialysis treatment using a dialysis machine with an arterial line for withdrawing blood from the patient's body, a dialysis filter, and a venous line for returning blood to the patient's body. The method induces a disturbance in the blood flowing in the venous line. The disturbance is of a magnitude capable of bringing the system into a transient state and determining blood recirculation in the vascular access during the transient state as a function of the magnitude of the disturbance induced in the arterial line. In particular, the disturbance relates to the variation of the hemoglobin concentration in the blood flowing in the venous line. The variation is caused by controlling a change in the ultrafiltration flow in the dialysis filter.

Abstract: Outer loop/weighted open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. A first communication station (110) transmits a communication to a second communication station including target adjustment information generated at the first station on the basis of measured error rates of communications from the second station to the first station. The second station receives the communication and measures its received power level. Based on in part the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the second station to the first station is based on in part weighting the path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted from the first station.

The first and second stages are performed one after the other in the same oven by proceeding, after the end of the first stage, with the steps of switching the gaseous effluent outlet from the oven to interrupt a connection with a first extractor device and to establish a connection with a second extractor device, of adjusting the pressure inside the oven to the value required for the second stage, and of adjusting the heating temperature of the oven starting from the temperature reached at the end of the first stage. It is also possible to switch temperature measurement from at least one first sensor to at least one second sensor different from the first. During the second stage, any alkali metal such as sodium contained in sublimed form in the gaseous effluent coming from the oven can be neutralized, e.g. by injecting CO<SUB>2 </SUB>into an effluent exhaust pipe.
