Abstract: An educational device to measure the strength and deflection of a sample truss comprises a mounting base having opposing posts, an adjustable sliding force plate, a load clip, a pulling means, a force measuring means, and a deflection measuring means. The truss has a longitudinal side and an opposing side with a load point, and a first end and an opposing second end.

Abstract: The present invention realizes a structure that can ensure silence during position adjustment of a steering wheel 8 by a feed screw mechanism 16, and that can achieve an improvement in the protection of a driver at the time of a collision accident. A nut 17 being a driven member is mounted such that it can be detached from an inner column 3a constituting a steering column 1a, based on a shock load applied at the time of a secondary collision. Therefore, at the time of a secondary collision, a threaded rod 18 constituting the feed screw mechanism 16, does not have resistance with respect to displacement of the inner column 3a in the forward direction, and hence an improvement in the protection of the driver can be achieved. Moreover, since an integrated member can be used for the threaded rod 18, silence during the position adjustment can be ensured.

Abstract: The present invention relates to a method and apparatus for the production of titanium alloys and titanium-aluminium inter-metallic compounds and alloys. Starting from a precursor material including titanium subchloride (titanium trichloride or titanium dichloride), the precursor material is reduced by aluminium to produce titanium-aluminium intermetallic complexes or alloys and aluminium chloride which is driven away from the reaction zone so as to favour the forward reaction and the production of the titanium-aluminium compounds. Starting from a precursor material of titanium subchloride avoids the problems associated with starting from titanium metal (which is expensive to produce) or titanium tetrachloride (a reaction very difficult to control), and results in the production of powdered forms of titanium-aluminium compounds with controllable composition.

Abstract: A portable hand-held screw driving tool is provided for use with collated strips of screws. The front portion of the tool is movable to a great extent, to thereby allow the tool to drive screws almost directly at the corner of two walls.

A screw is indexed to its drive position, and a drive bit is abutted against the screw head during this first stage. The nose piece is pressed further into the tool, which also causes a “feed tube” to move rearward “into” the remainder of the tool, in a “second stage” of movement, which rotates the screw as it is emplaced into the wall.
