Abstract: ABSTRACT OF THE DISCLOSURE    An improved prosthesis is provided herein for maintaining the intra-abdominal reduction of a sliding esophageal hernia.  The prosthesis comprises a generally C-shaped cushion which is positioned around the distal esophagus between the diaphragm and stomach.  The overall size of the prosthesis is large enough to prevent extension of the gastric fundus into the thoracic cavity through an enlarged esophageal hiatus.  The pros-thesis is of generally constant cross-sectional area along its entire length to prevent upward migration of the prosthesis through the enlarged esophageal hiatus and to maintain the accentuated curvature of the esophagus induced by emplacement of the prosthesis.  Tie means are pro-vided to maintain the prosthesis in operative position.  Radiopaque indicia are also preferably provided to facilitate radiographic determina-tion of the position of the prosthesis after emplacement thereof.

Abstract: ABSTRACT OF THE DISCLOSURE         An arrangement for adjusting an adaptive digital balance filter included in a subscriber unit connected to a telephone line contains a selection unit which can be connected to the subscriber unit either via the exchange or via a separately arranged switch.  When the selection unit is connected to the subscriber unit, the balance filter is disconnected from both branches of the subscriber unit. A test signal generator is included in the selector unit for sending a signal on the lines via both branches of the subscriber unit.  There is further included a  plurality of N digital filters where the transfer function of any of the filters closely coincides with the transfer function of the filter formed by the line impedance and the portion of the subscriber unit which is connected to the line and to the balance filter.  By means of a measuring unit there is formed a criterion for determining which one of the filters included in the selector unit most closely matches the above-mentioned filter, and the parameters of the selected filter are allowed to determine the parameters of the balance filter.

Abstract: ABSTRACT OF THE INVENTION           In situ measurement of the gas content of for-mation fluid using thermal expansion principles.  The formation fluid from a wellbore source is passed through an expansion type valve into a test chamber.  The temperature and pressure are measured upstream and downstream of the valve.  The difference in the temperature measurement is an indicator of gas content in the formation fluid.  Samples of the formation fluid can be taken on favorable indicators.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for providing improved rotation-al speed determination for a rotating shaft.  Two probes positioned adjacent a circular disk which rotates with the shaft scan markings on the disk and generate four out-of-phase signals in response to rotation of the shaft.  A switch, controlled by logic circuitry which detects intersections of the signals, develops a composite saw-tooth-shaped signal from the four signals. A counter counts the number of crossings of the composite signal with a refer-ence "zero" value to develop a determination of the number of discrete angular positions traversed by the shaft during a specified time interval.  A memory stores the value of the composite signal at the start of the time interval. Computation circuitry develops a rotational speed based on the counted number of positions, corrected by a factor derived from the difference between the stored value and the value of the composite signal at the end of the interval. Time control circuitry prevents the start or end of the time interval during switching and prevents switching during the start or end of the time interval.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus and method for pumping oil or other fluids from the earth is disclosed as using a submersible pump which is suspended in a hole drilled into the earth by means of a flexible cable.  Encased in a flexible sheath with the cable are a power cable for the pump and a flexible hose to carry the oil from the pump to the surface of the earth.  Control and signal wires may also be encased in the sheath for connec-tion to transducers mounted on the pump.  The pump may be easily inserted into or removed from the hole by using a reeling mechanism on the surface of the earth.  The pump itself may comprise a submersible motor connected to a rotary to linear motion transducer that causes a pump barrel to reciprocate.          The pump barrel moves over a stationary pump plunger, and there are ball check valves in both the barrel and plunger to control the entrance and exit of oil.

Each block comprises two oppositely situated, parallel, light-transmissive principal surfaces and two side surfaces which are also oppositely situated and which extend from one principal surface to the other.  On the side surfaces there are provided two electrodes which are connected to two conductors which are constructed as surface wiring.  The electrodes and/or the connection between the carrier and the conductors are preferably also formed to be flexible.  This construction offers the advantage that the various blocks cannot mechanically or electrically interact with one another.

Abstract: ABSTRACT OF THE DISCLOSURE:         A microbial diagnostic method based on the hybridization of nucleic acids on a solid carrier, and a reagent combination for carrying out the method.  The method which can be used to identify all the microbes or microbial groups from a single sample containing nucleic acids of the microbes or microbial groups to be diagnosed, after having first rendered said nucleic acids single-stranded, basically consists in adding to the sample two nucleic acid reagents for each microbe or microbial group to be diagnosed.  One of these nucleic acid reagents consists of a nucleic acid fragment from the same microbe or microbial group, which is attached to a solid carrier in a single stranded form.  The other reagent consists of a completely different nucleic acid fragment from the same microbe or microbial group, which is labelled with a given marker.  The nucleic acid fragment attached to the carrier is selected to hybridize to a complementary single-stranded nucleic acid from the sample to form a hybrid on the carrier.  This hybrid becomes labelled when the labelled nucleic acid fragment anneals to it.  Of course, the nucleic acid reagents are selected not to hybridize to each other.  The labelled hybrid attached to the carrier can be measured using established methods.
