Abstract: ABSTRACT     A conduit conducting a dirty gas is connected by one line to an interface device connected by another line to a pressure measuring device having a cavity and a diaphragm defining one wall of the cavity.  The interface device has a pair of chambers in fluid com-munication at their upper ends.  The bottom end of one chamber is in fluid communication, via the one line, with the conduit conducting the dirty gas.  The bottom of the second chamber is in fluid communication, via the other line, with the cavity in the measuring device.  The second chamber, the cavity and the line connecting them are filled with a liquid which keeps dirt in the dirty gas from entering the cavity but transmits the pressure of the dirty gas to the diaphragm in the cavity.

One horizontal edge and two vertical edges of each are welded to the frame side portions adjacent the rear lateral portion.  Rear legs with integral back-support portions are welded to the other horizontal and vertical edges, so that they are spaced apart from each other farther than are the front legs.  The rear legs may be two separate members or there may be a single continuous member including both legs and joined at the top.  A seat (preferably non-rigid, resilient) bridges and is secured to the frame-side portions and urges them toward a truly parallel relation-ship, and a similar back bridges and is secured to the back-support portions and, if they diverge, urges them toward a truly parallel relationship.

Abstract: BUFFERED RECORDING                ABSTRACT            A forward/backward compatible apparatus and record member achieves multiple density by multiple track widths as well as multiple lineal densities.  In a rotating head recorder a single head has a wide write gap followed by a plurality of narrow read gaps.  In recording, narrower tracks--i.e., higher densities, the record medium is moved less than the width of the write gap for recording narrower tracks. The narrower tracks have the same width as the trailing read gaps.  During readback, all read gaps are simultaneously operative.  Signals from one of the read gaps are processed immediately, while signals from the remaining read gaps are buffered until a dead time occurs, such signals are then processed.  The same principles are applicable to magnetic card and magnetic disk recorders.  A record member of the disclosure employs a table of contents area always recorded at the lower density--i.e., widest track.  The table of contents contains indicia indicating the track density as well as the lineal density of the other recording areas.  The buffering also is employed to overlap seeks in a disk file for greater data accessibility.
