Abstract: The invention provides a process for coating a substrate including electrodepositing an electrodepositable composition on the substrate, heating the coated substrate to cure the coating thereon, applying over the cured electrodeposited coating one or more pigment-containing coating compositions and/or one or more pigment-free coating compositions to form a top coat thereover, and heating the coated substrate to cure the top coat. The elecrodepositable composition is formed from an ungelled cationic salt group-containing resin where the salt groups are formed from pendant and/or terminal amino groups, and an at least partially blocked aliphatic polyisocyanate curing agent. Also provided is a photodegradation resistant multi-layer composite coating of a primer layer formed from the electrodepositable composition and a top coat thereover, where the composite coating exhibits substantially no interlayer delamination upon concentrated solar spectral irradiance exposure equivalent to two years outdoor weathering.

Abstract: A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.

Abstract: A converter dolly replaces the rear wheels of a truck trailer to provide the trailer with a steering ability about its rear wheels. The converter dolly is modified to include a hydraulic actuating system, including a piston, cylinder, and pump assembly, which act upon the tongue of the converter dolly to pivot the converter dolly about a king pin. The actuation of the hydraulic system is performed by the driver of the tractor towing the trailer through a control system mounted in the tractor cab.

Abstract: A quick implement attachment mechanism (2) utilizes a single coupling unit having two receiving sides (18) interconnected by a longitudinal beam (20). Each receiving side of the mechanism will engage a pair of vertically aligned pins (12 and 14) mounted on each side of an implement (6). The bottom portion of each receiving side has a bottom U-shaped member (28) which engages the lower pin at the same time a top U-shaped member (26) proximate the upper portion of each receiving side engages the upper pin. A fold-up and fold-down dog 32 positively locks the upper pin within the upper U-shaped member, maintaining both the upper and lower pins within the U-shaped members of the quick attachment mechanism.

Abstract: In accordance with the present invention, metal pigments are provided which are normally reactive with water or moisture to release hydrogen gas ("gassing") and which have been stabilized against such gassing by having their surfaces treated with an adduct of a maleinized fatty acid and/or a maleinized alpha-olefin and a polyol. Waterborne film-forming compositions which comprise an aqueous diluent medium, a film-forming polymer, and metal pigment stabilized against gassing by treatment with an adduct of a maleinized fatty acid or a maleinized alpha-olefin and a polyol are also provided.

Abstract: A waterborne coating composition having improved smoothness is provided which contains a polymeric film-forming resin in aqueous medium and from about 0.1 percent to about 10 percent by weight based on total weight of resin solids of at least one material having the following structure: ##STR1## where n is an integer that is at least 1, R.sup.1 is hydrogen or lower alkyl having 1 to 10 carbon atoms, R.sup.2 is a divalent organic radical, and R.sup.3 is an alkyl, aryl, or alkylaryl group having 1 to 20 carbon atoms.

Abstract: A method of forming a multilayer coating on a substrate utilizes a pigmented aqueous based coating composition. The aqueous based coating composition contains a polymeric film-forming resin and as an additive from about 1 to about 40 percent by weight based on the resin solids of the composition of an oligomeric ester having an acid value of from about 100 to about 500 of the structure: ##STR1## where X is the residue of a polyol containing from 1 to 50 carbon atoms per hydroxyl group after reaction with an acid or an anhydride, R is an organic moiety from the acid or anhydride and A has an average value of about 2 or greater. The coating compositions are particularly advantageous as metallic pigmented coating compositions for automotive basecoat applications because they exhibit excellent resistance to mottling, have good flop and have reduced sensitivity to fluctuations in relative humidity.

Abstract: N-acyl aminomethylene phosphonates are provided having a group defined by the following general formula: ##STR1## wherein R.sub.1 is hydrogen, an aliphatic radical having 1 to 25 carbon atoms, or an aromatic radical having 6 to 25 carbon atoms; R.sub.2 is hydrogen, an aliphatic radical having 1 to 25 carbon atoms, or an aromatic radical having 6 to 25 carbon atoms; and R.sub.3 is a group remaining after reaction of a hydroxyl group-containing or epoxy group-containing polymer with an acidic hydrogen of a ##STR2## group. Also provided are waterborne coating compositions containing metallic pigments which are normally reactive with water or moisture to release hydrogen gas, stabilized against gassing by incorporation of these N-acyl aminomethylene phosphonates into the waterborne coating compositions.

Abstract: A method and system is provided for moving passengers in and out of an amusement ride of the type having a passenger cabin capable of movement in multiple degrees of freedom within an enclosure. The cabin includes ingress doors on one side of the cabin and egress doors on the other side to admit and discharge passengers from seats within the cabin. Another set of ingress and egress doors are provided on opposite sides of the enclosure in respective alignment with the ingress and egress doors of the cabin when the cabin is at rest in a loading position. A plurality of ingress and egress platforms, located outside the operating envelope of the cabin when the cabin is in motion, are adapted to be moved to a deployed position when the cabin is in the loading position to connect the ingress and egress doors of the enclosure with the ingress and egress doors of the cabin. In this way, movement of passengers in and out of the cabin, which is spaced from the enclosure, is provided in a rapid and orderly fashion.
