Abstract: ABSTRACT OF THE INVENTION     A process for brazing a sleeve within a tube which is resistant to longitudinal expansion is disclosed herein. In the first step of the process, a thermally induced radial expansion is induced in the tube in a first longitudinal section of the tube which does not include the ring of brazing alloy which circumscribes the sleeve.  In the second step of the process, a brazing heat is applied across the longitudinal section of the tube which does include this ring of brazing material. The residual tensile stress created by the thermally induced radial expansion in the tube avoids the creation of gaps in the braze joint between the sleeve and the inner walls of the tube. This process is particularly useful in creating high-quality braze joints in sleeving operations in nuclear steam generators, where the heat exchange tubes which need to be sleeved may be partially or completely prevented from expanding in the longitudinal direction due to sludge deposits in the generator.

Abstract: COMPUTER SYSTEM FAULT RECOVERY  BASED ON HISTORICAL ANALYSIS     Abstract A method of identifying faulty units in a computer-controlled system. The system units generate error reports in response to the detection of error conditions.  When an error report is received, an initial list is generated containing probable fault weights for each of the system units based on the type of the error report.  The probable fault weights are prespecified based on a logical analysis of the fault modes and error propagation paths in the system.  A history list of fault weights is first aged and then combined with the initial list to generate a resultant list.  The resultant list becomes the new history list.  The resultant list is then masked by the initial list to form a selection list from which a most probable fault unit is selected.

Abstract: ABSTRACT A marine riser safety valve is disclosed which, when placed in series with a deep water marine riser string, prevents collapse of riser pipe when in-advertent gas influx replaces the drilling fluid column.  A cylindrical body is provided having a depression formed therein with at least one diaphragm port from the central bore of the body through the wall of the depression.  A valve port is provided axially from the depression.  A cylindrical member including a cylindrical diaphragm and a valve sleeve are joined end-to-end.  The cylindrical member is disposed about the exterior of the body with the elastomeric diaphragm covering the depression and the valve sleeve covering the valve port.  When a dif-ferential pressure develops across the wall of the diaphragm of a predetermined threshold, the diaphragm constricts into the body depression and moves the valve sleeve axially, opening the valve port to permit sea water influx.  An outer skirt is provided to prevent outward ballooning of the diaphragm when bore pres-sure is greater than the surrounding sea water pres-sure.

Abstract: ABSTRACT OF THE DISCLOSURE     Sand molds stored in a prepour storage system are retrieved and conveyed to a pouring station with a total mold cavity capacity equal to the amount of molten metal to be poured.  Despite the fact that the mold cavities vary in size they are delivered to the pouring station in a sequence that accommodates delivery of the molds having variable metal capacity to one of a plurality of cooling conveyor lines so that each cooling line conveys molds which require variable lengths of time to cool before such molds can be conveyed into a punchout where the cope flask is stripped and the sand mass and castings are pushed up from the drag flask and onto a shakeout which conveys sand to a reclaim system and castings to a processing area where the castings are shot blasted, gates and risers  are removed, the castings are inspected, flame washed, welded (as needed), ground, chipped, heat treated and then blast cleaned a second time before final grinding, chipping, gauging, final inspection, assembly and storage. The mold flasks are cleaned, new mold cavities formed therein and are reassembled and then stored in the prepour storage system where their location is recorded by a computer for selective retrieval for the next heat to be poured.

Abstract: An insole comprises a lower layer 4, composed of a mixture of elastic material and cork, one or more intermediate layers 3, composed of a foam material, such as foam rubber, and an upper leather layer 2 which possesses a border 20 which protrudes outside the intermediate layer or layers 3. The elastic material of the lower layer 4 is polyurethane. The width of the border 20 of the upper leather layer 2 is quite small and the thickness of the border 20 is at least 1.5 mm. The border 20 is surrounded on three sides by the polyurethane-cork mixture 4. This results in an insole which enables the border of the leather layer to be anchored more reliably on the underlying material such that the insole tolerates a very large number of flexions without the leather layer or the border becoming loose. <IMAGE>
