Title: Head closure apparatus for heat exchanger
Inventor: LAWRANCE HAROLD R
IPC: F28F9/06
Filed: 1989-01-24
Granted: 1991-03-26
Abstract: HEAD CLOSURE APPARATUS FOR HEAT EXCHANGER     Abstract of the Disclosure The invention discloses a novel head closure apparatus for shell and tube-type heat exchangers.  The disclosed appara-tus is substantially resistant to thermal stress cracking in that it has an internal closure chamber configured to withstand and dissipate thermal stresses caused by rapidly changing ther-mal gradients.  The apparatus also provides for full access to the entire interior volume of the head closure and to the entire area of the head closure inner tubesheet surface in order to facilitate maintenance and repairs.         The invention also discloses a compact and efficient retaining key apparatus for constraining the end-cover of a cylindrically-shaped head closure member against internal work-ing pressures.  The apparatus enables substantial reductions in the masses of the retaining keys, the head closure member, and the end-cover, which results in the head closure apparatus be-ing simpler and more economical to manufacture and maintain.     Background of the Invention 1.   Field of the Invention.     The invention relates to pressure vessels or heat exchangers, and more particularly to a head closure apparatus for use with shell and tube-type heat exchangers.         In particular, the invention relates to an easily main-tainable heat exchanger head closure apparatus suitable for cycli-cal modes of operation over rapidly changing thermal gradients, in that the apparatus is highly resistant to thermal stress crack-ing which has become a problem in heat exchangers presently being used in the electrical power generation industry, among others.

Abstract: ABSTRACT OF THE DISCLOSURE            There is disclosed an apparatus for displaying the constantly changing current location of a vehicle on a two-dimensional coordinate system while detecting the distance travelled by the vehicle and its direction of travel.  The current location is displayed on a map on a display screen on the basis of computed data.  The apparatus extracts a linear travel segment from the current location of the vehicle by storing data of the current location, extracts a linear road segment from adjoining roads on the map, which corresponds to the linear travel segment extracted from the current location, matches the extracted travel segment and linear road segment depending on their positional relationship, and puts the current location onto the road for which matching has occurred.
