Abstract: An array of plate-like elements is retained by endless filaments looped on the elements to form migrating hinges between individual elements and other elements adjoining same. Grooves are formed in the surfaces of each plate, the grooves being in two groups, with the members of each group being mutually parallel, and the grooves of each surface being in overlying registration. The filaments lie within the grooves in a selected pattern, with filaments forming anchor points at plate sides at which the filament wraps around the side of the plate to enter a groove from the other group of grooves on the opposite side of the plate, and hinge points at plate sides where the filament passes from one plate to an abutting plate, proceeding from one surface to the opposite surface in doing so. Manipulation of the resulting array allows two such plates to rotate mutually about an axis defined by hinge points lying on their abutting sides.

Abstract: Low temperature fired dielectric ceramic compositions are prepared by firing, at temperatures between about 1000.degree. C. and about 1150.degree. C., a base ceramic preparation comprising barium titanate, strontium titanate, barium zirconate, titanium dioxide and manganese dioxide mixed with a glass frit comprising zinc oxide, silicon dioxide, boron oxide, lead oxide, bismuth tioxide, and cadmium oxide. The resulting dielectric ceramic composition is useful to form multilayer ceramic capacitors.

Abstract: A device for anchoring and directing medical tubing comprising a plate of flexible resilient material having an internal curved passageway(s), open at both ends, with a cross sectional area at least in segments thereof no greater than the cross sectional area of the tubes to be anchored. Each passageway communicates with a face of the plate by means of a slit or cut extending from the passageway wall to the surface of the plate along the entire length of the passageway. The plate may also be provided with slots remote from each other and from the passageway and extending completely through the plate, and with an elastic belt adapted to affix the plate to a patient by passing through one such slot, over the slit surface of the plate, through the other slot and around a member of the patient's body.
