Abstract: An improved prosthesis (20) 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 (17) between the diaphragm (13) and stomach (45). 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 prosthesis 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 (17) induced by emplacement of the prosthesis. Tie means (27) are provided to maintain the prosthesis (20) in operative position.

Abstract: Disclosed is a method and apparatus for measuring and controlling volumetric flow rate of gases, and especially for delivering gases at a selected and measured volumetric flow rate. The apparatus includes a measurement chamber (14) of fixed volume in a flow line (11), a controllable inlet valve (15) upstream from the chamber, and flow regulator means (12, 13) for establishing constant flow output downstream from the chamber. Also provided are measuring and control equipment including a pressure sensor (16) in the chamber, means (17) for controlling operation of the inlet valve, timing means, and means for calculating volumetric flow rate. The method involves closing the inlet valve at a chosen time for a selected interval, to interrupt flow into the measurement chamber, while maintaining constancy of flow out of the chamber. During at least part of the interval in which the inlet valve is closed, the pressure decrease is measured, and the rate of pressure decrease is calculated by dividing the measured pressure drop by the time measured by the timing means. The thus calculated rate of fall of pressure is directly related to the volumetric flow rate, which is thus determined. If the nature of the gas and the flow conditions are such that the supercompressibility of the gas should be taken into account, rate of pressure fall is determined at two time intervals. If the two rates are the same, no correction is needed. If they differ, a supercompressibility correction factor is applied to the calculation of rate of pressure fall.

Abstract: In spaced relationship from an infeed track or path for an imbricated product formation there is arranged an outfeed track or path. Between the infeed and outfeed tracks there is provided a group of movable track elements which are spaced in overlying or superimposed relationship from one another in their direction of movement. This group of track elements is guided and moved transversely with respect to the infeed and outfeed tracks or paths. Conveyor means serve to transfer the printed products from the infeed track in each case by means of one of the track elements to the outfeed track. In this way it is possible, without releasing the printed products out of the imbricated product formation and without altering the movement of the imbricated product formation or interrupting such movement, to render accessible each of the printed products for performing further processing operations thereat during the throughpass thereof at the relevant track element.
