Abstract: A ball joint apparatus for a pressurized fluid line includes a bellows and a pair of opposed tube portions to accommodate limited flexure between the tube portions. The apparatus also includes an annular ball element positioned over one of the tube portions and an annular housing member mounted on the other tube portion and overlapping the ball member. As initially formed, the overlapping end of the housing member is open and of a diameter exceeding the maximum diameter of the ball member to permit ease of assembly. After the component parts are in position and welded as desired, the apparatus is placed in a hydraulic press and the open end of the housing member is necked down by a swaging process to establish bearing contact with the ball member. Alternative arrangements of the apparatus are provided for use with stainless steel tubing and with titanium tubing.

Abstract: A sheet of flat paper or poster stock has information printed on one side in the form of separate and independent areas of discrete information units, and a large-scale poster-like pattern occupying substantially the entire available area of the opposite side surface of the sheet. A plurality of straight crease lines are marked on one surface of the sheet, arranged to define a coordinate grid-like pattern surrounding the various discrete information units, such that the sheet may be folded conveniently along the crease lines to form a fold-out booklet having a plurality of leaves with units of information printed on each leaf, similar in nature to the pages of a book.

Abstract: A collapsible box-like container of the type constructed to fold flat for storage and shipping, is provided with a reverse integral hinge portion which is positioned to lie in abutting parallel relation with a second integral hinge on the opposite side of a third integral hinge portion when the container is folded flat; the reverse hinge and the second hinge may be displaced simultaneously in nested relationship to define an exterior angle at the reverse hinge which is substantially congruent with the interior angle formed at said second hinge. This construction permits the effective width of the flattened container to be reduced for shipment by folding into a right angle shape so that it conforms to the exterior configuration of another object such as a book or a separate, rigid box, for example.
