An exercise assembly structured to direct the foot-ankle-leg, knee, etc. and associated portions of a person's body through a plurality of different paths of movement, wherein each path of movement comprises an at least partially different configuration such that exercise resulting from the various movements will be concentrated on predetermined portions of the body being exercised. The platform is suspended by a support assembly interconnected to a base and is preferably, but not exclusively, directed through the aforementioned paths of movement manually by the user. A sensor assembly including a processor may determine and store selected movements of the platform for graphical or other visual display to the user and for programmed duplication of the sensed paths movement when desired. A weight assembly including at least one but preferably a plurality of different weights are interconnected to the platform and extend outwardly therefrom to provide additional resistive forces to the user's foot, ankle, and leg as they are exercised.

A pressure vessel and method for producing a pressure vessel is disclosed. The pressure vessel comprises a liner shell fabricated from composite material applied to a soluble mandrel having a body shaped to pattern an interior of the pressure vessel, the liner shell having an opening, a boss having an aperture therethrough, the boss sealingly bonded to the liner shell with the aperture adjacent the opening, and an outer shell fabricated from plies of composite material filament impregnated with matrix material wound over the liner shell and the boss, but not over the aperture.

There is provided a prefabricated window / door structure with interconnecting 45 degree joints where a horizontal bar has its both ends cut at an angle of 45 degrees and includes: a first connection space formed in the direction of the length of the horizontal bar so that the inner space of the horizontal bar is open to the outside, and a screw fastening part with a screw fastening groove protruding in the first connection space; a vertical bar has its both ends cut at an angle of 45 degrees to form a joint of 45 degrees when each of the ends of the vertical bar faces each of the ends of the horizontal bar and includes: a second connection space formed in the direction of the length of the vertical bar so that the inner space of the vertical bar is open to the outside, and a screw hole formed on a side wall in the second connection space, to be aligned with the screw fastening groove; and a support block includes: a first support part to be inserted into the first connection space of the horizontal bar and a second support part to be inserted into the second connection space of the vertical bar. The first support part includes a fastening part receiving channel formed to receive the screw fastening part when the first support part is inserted into the first connection space.Accordingly, since the horizontal bar and the vertical bar are simply attached to and / or detached from each other, it is easy to install and repair the window / door. Further, since the thickness of the horizontal bar and the vertical bar is able to be minimized, the window / door is light in weight. In addition, the joint of the horizontal bar and the vertical bar is more strongly reinforced by the reinforcing piece(s).

Gusset plates are incorporated for reinforcement at the junctions of the wide flanged, cross and longitudinal beams of a rig mat frame. The junctions thus have a square tubing configuration.

A rail joint assembly joining the ends of two rails together includes a pair of joint bars. Each joint bar having one side configured to the rail web side. Mechanical fasteners mount the joint bars to the web sides. Pairs of load bearing keys are embedded in web counter bores at predetermined depths into the webs and embedded in adjacent joint bar counter bores at predetermined depths into the joint bars. The pairs of keys in the webs and the joint bars transfer railway loads through the joint and substantially strengthen the rail joint assembly.

Embodiments of the present invention provide high durability joints between ceramic articles, particularly between beta-silicon carbide (β-SiC) articles, and methods of making and using the same. In one embodiment, a joint between first and second articles each comprising a ceramic polymorph comprises a matrix comprising the ceramic polymorph and extending between the first and second articles; a plurality of inclusions comprising the ceramic polymorph and being distributed throughout the matrix; and a sealing layer comprising the ceramic polymorph and being respectively disposed on the first and second articles and the matrix.

In a method of producing a stabilizer for a motor vehicle, a stabilizer bearing portion of a stabilizer is chemically pre-treated by applying an adhesive. The stabilizer and two vulcanized elastomer-metal bearing half-shells are then placed in a joining apparatus for subsequent bonding of the bearing half-shells with the stabilizer bearing portion.

A plate for the use in a heat exchanger cassette, where the plate comprises a corrugated pattern having a plurality of ridges (9) and valleys (10), and where the plate comprises a sealing gasket groove (3) encircling a heat transfer surface (8) that will be part of a contact-free fluid channel when two cassettes comprising at least one plate each are positioned adjacent each other, wherein the sealing gasket groove (3) comprises a base surface with a first, flat section (12) and a second, bent section (13), and where the bent section is angled with the angle α. The advantage of the inventive plate is that an airtight heat exchanger cassette can be obtained in an easy and cost-effective way.

A microelectronic package can include a substrate having a first surface and a plurality of substrate contacts at the first surface and a microelectronic element having a front surface and contacts arranged within a contact-bearing region of the front surface. The contacts of the microelectronic element can face the substrate contacts and can be joined thereto. An underfill can be disposed between the substrate first surface and the contact-bearing region of the front surface of the microelectronic element. The underfill can reinforce the joints between the contacts and the substrate contacts. A joining material can bond the substrate first surface with the front surface of the microelectronic element. The joining material can have a Young's modulus less than 75% of a Young's modulus of the underfill.

Systems are disclosed to restrain movement of engine components in the event of a collision. A system may comprise an upper intake manifold; a cam cover; a shear catch located between the upper intake manifold and the cam cover; an upper component of the shear catch is arranged on the upper intake manifold; a lower component of the shear catch is arranged on the cam cover; and the upper component and the lower component are arranged opposite each other such that they engage when the upper intake manifold is subjected to shear forces. Variations to the size, arrangement, and shape of a shear catch are disclosed herein.
