摘要:
A fastener device for releasably securing an object within an opening formed in a structure comprises a first fastening member and a second fastening member each having a pair of legs which are oriented at an angle relative to one another. A coupling element is movable along one of the legs of at least one of the first and second fastening members. One leg of each fastening member is inserted into a hole formed in the structure surrounding the opening allowing the other leg to pivot, preferably in a trochoidal motion, until the pivoting legs align with one another at which time the coupling element may be moved into engagement with the two pivoting legs to releasably connect the fastening members together in position to secure the object relative to the opening.

摘要:
A composite beta, mainly beta"-alumina article is described which comprises a first layer of beta-alumina, a second layer of mainly beta"-alumina adhering securely to the first layer, and the first layer consisting of 1 to 15 percent thickness of the total thickness of the article. A method is also described for producing such composite articles.
摘要:
A method of producing lithiated beta-alumina articles includes electrophoretically codepositing such material onto a mandrel from two powders, drying the deposited material, and sintering the dried material. Such articles are useful as containers for sodium and as solid electrolytes in sodium-sulfur and sodium halogen batteries.
摘要:
A method of preparing a suspension of additive-free beta-alumina particles includes vibromilling water free beta-alumina particles of a diameter larger than 2 microns in an organic fluid having a dielectric constant at 25.degree.C of from 12 to 24 with beta-alumina grinding media. The resulting suspension is useful for forming beta-alumina articles by electrophoretic deposition.

摘要:
A sintered .beta.-alumina cylindrical tube of uniform shape is produced by placing the unsintered tube within a sagger, passing the sagger on friction-reducing balls through a horizontal firing tube and rotating the tube-containing sagger through the firing tube.
摘要:
A battery casing and a sealed sodium-sulfur battery are disclosed wherein the battery casing includes separate seals of low temperature melting glass joining a portion of an inner casing of a solid sodium ion-conductive material to the interior surface of a ceramic ring, and joining two opposed outer metallic casings to the ceramic ring. A sealed sodium-sulfur battery has the above type of casing with a sodium anode in one casing and a cathode of sulfur in conductive material in the other casing.
