    Abstract: A main ramp member, having a first end and a top surface, is provided with two base members telescopingly mounted for transverse movement at either side thereof and means for mounting the first end to a trailer for rotation of the main ramp member between a loading position and a transporting position. Each of two receiving ramp members has a first end pivotally mounted proximate to the first end of the main ramp member to a corresponding base member below the plane of the top surface thereof. When the main ramp member is in its loading position, each receiving ramp member is elevated above the base member by a foot member which contacts the ground. When the main ramp member is in its transporting position, each base member supports the receiving ramp member mounted thereto below the plane of the top surface of the main ramp member. Bars are provided which cooperate with the receiving ramp members to form two wheel receptacles in which the rear wheels of wheel mounted machinery are disposed and thereby restrained against rotation when the main ramp member is in its transporting position.

    Abstract: A plasma-deposited coating of a heat-treatable titanium carbide tool steel composition is formed upon the surface of a ferrous metal core, the coating being thereafter transplanted onto a conforming surface of an aluminum substrate by pressure casting aluminum against said core to effect bonding of said aluminum to said coating. Because the coating is cooled rapidly on the core during plasma deposition from above the austenitizing temperature of the steel, a hardened coating is provided having a microstructure containing an austenitic decomposition product selected from the group consisting of martensite, bainite and mixtures thereof. After pressure casting, the core is disengaged from the aluminum surface by differentially cooling the core relative to the casting so as to release the core, thus enabling the core to be removed from the casting, the coating being transferred to the aluminum substrate. The hardened structure is maintained in the coating even after it is transplanted onto the confirming aluminum surface. Preferably, the titanium carbide grains are rounded to assure a low friction surface.

    Abstract: A method is provided for improving the corrosion resistance of material substrates. The method is particularly applicable to the protection of metal substrates, such as ferrous metal articles, among other metals, and, in particular, to the protection of low alloy steel gas turbine engine components for aircraft in which the surface is provided with an adherent protective layer of a sacrificial coating rich in magnesium and also containing silicon, oxygen and optionally iron. The coating is characterized by the presence of magnesium silicide as a major active constituent.

    Abstract: The invention contemplates a vane-twist measuring or gaging instrument in which the overall twist of the vane is assumed to be indicated by the angular relation between a reference alignment, taken on one buttress surface, and a measured-offset alignment, taken on the corresponding surface of the other buttress for the same vane. Basically, a reference plane is established for the reference surface of the first abutment, as by using two fixed and precisely positioned spaced point-contact elements, and a gage carried by the instrument near the other buttress senses the inclination of the other buttress (with respect to the reference plane) when the other buttress is applied against a single, or third, fixed point of support on the instrument. In one form, the third support point is established by an elongated bar, with provision for central pivotal support, so that its angular orientation about the pivot may reflect contact with, and therefore slope of, the other vane buttress; in another form, the third support point is a fixed abutment near one end of the other buttress, and a probe responds to a given location near the other end of the buttress when the vane is applied to the three fixed support contacts.

    Abstract: In the production of impact and oxidation resistant nickel-base metal coatings on heat resistant superalloys by pack aluminizing in which nickel aluminide is formed to provide the protective coating, markedly improved ductile coatings are produced of high impact resistance by controlling the amount of aluminum in the pack which also contains about 5 to 40 percent by weight of chromium, the amount of aluminum not exceeding 3 percent by weight of the pack.
