Patent ES-461924-A1 (ES)
Title: Analog-to-digital converter circuit employing iterative subtraction
IPC: H03M1/38
Filed: 1977-08-27
Abstract: An analog-to-digital conversion circuit having a number of series-connected stages, each stage determining the difference between a signal current input and a reference current input, and at positive values of said difference transferring a current proportional to said difference to the succeeding stage. In each successive stage, the reference current is subtracted from the signal current until the residual current is smaller than the reference current. The number of successive stages in which this subtraction takes place can be detected to indicate the level of the input current. Each stage includes a common point for receiving the difference between the signal current and the reference current, a current path from said common point to its output for transferring a current proportional to the difference if positive, a current path from said common point to a current sink if said difference is negative said current paths being unidirectional and biased such that only one is forward biased at one point in time. Each stage also detects the polarity of said difference to obtain a digital measure of the value of the signal current.

Title: Marine production riser system and method of installing same
IPC: E21B43/01
Filed: 1979-07-09
Abstract: A free-standing, marine production riser and a method of installing same for use in deep-water areas to conduct fluids between the marine bottom and the surface. The riser system is comprised of a lower rigid section and an upper flexible section. The lower rigid section has a casing extending from a preset base on the marine bottom to a point just below the zone of turbulence which exists near the surface of the water. A variable-buoyant buoy having a curved upper surface and a central passage therethrough is mounted on the upper end of the casing to support the casing in a substantially vertical position when the casing is in position on the preset base. A remotely actuated connector assembly is provided on the lower end of the casing for connecting the casing to the preset base. A plurality of conduits are run through the passage in the buoy and through guide means in the casing and are remotely connected to mating conduits on the base. Each of a plurality of flexible flowlines is connected to a respective conduit at a point within the passage in the buoy. Each of the flexible flowlines is of sufficient length to extend over the upper curved surface of the buoy which provides a natural bending radius for the flexible flowlines and then downward through a catenary loop before extending upward to the surface. The flowline length also will be sufficient to maintain a catenary loop in the flowline at all times during normal operating conditions. All of the upper ends of the flexible flowlines are connected to a single flange which, in turn, is adapted to be quickly connected to and disconnected from a floating facility at the surface. In turn, each flexible flowline can be individually installed and/or removed.

Title: Method and device for controlling the cuff pressure in measuring the blood pressure in a finger by means of a photo-electric plethysmograph.
IPC: A61B5/02
Filed: 1982-10-28
Abstract: Arrangement for controlling the cuff pressure in the indirect, non-invasive, continuous measurement of blood pressure in a finger by using a photo-electric plethysmograph in a fluid-filled pressure cuff, an electronic control circuit and an electric pressure valve, the cuff pressure being controlled by the plethysmographic signal in closed-loop operation by means of a servo-reference level, so that the arterial volume is maintained at a pre-adjusted value. For initial adjustment, the cuff pressure or the servo-reference level as initial adjustment quantity is automatically changed continuously in the control range by means of a control waveform supplied to the electronic control circuit, that thereby the peak-through amplitude of the pulsatile plethysmographic signal or cuff pressure signal is detected time and again, and compared with the preceding peak-through amplitude. The biggest value thereof in the control range and the associated value of the cuff pressure at servo-reference level are stored, which value of cuff pressure or servo-reference at the end of the initial adjustment is used as set value for the measurement of the blood pressure.
