Abstract: Hydraulic binder reducing formulation, agent or additive for cementitious compositions, cementitious compositions containing same, and method of preparing the same. The binder reducing formulation comprises carbon nanotubes, preferably functionalized carbon nanotubes, most preferably carboxylic acid functionalized multi-wall carbon nanotubes. The binder reducing formulation may also comprise one or more of silane, glycerol, nanosilica and a surfactant. The cementitious compositions including the binder reducing formulation achieve strength values equal to or greater than strength values achieved with similar or identical cementitious compositions but devoid of the binder reducing composition.

Abstract: The present application describes a gooseneck coupler assembly that may include a gooseneck trailer pivot, an extension arm, and a pivot retention mechanism having a ball socket. The ball socket may engage with a hitch ball located on a towing vehicle. The gooseneck trailer pivot may be mounted on a towed vehicle or trailer and be capable of pivoting about a vertical axis relative to the trailer. During engagement, the ball socket and the extension arm may provide tilt capability but thereby prevent any rotational movement relative to the hitch ball. However, the gooseneck coupler assembly may still be able to tilt fore-and-aft or side-to-side relative to the hitch ball. Therefore, the only pivotal movement relative to a vertical axis would be permitted at the gooseneck trailer pivot.

Abstract: Apparatus for a bike rack for securing at least one bicycle are described herein. The bike rack is attachable to a vehicle receiver hitch. The bike rack includes a hub assembly, hitch insert assembly, and support wing assembly. The tub assembly includes a pair of hubs each having an arm. The hitch insert assembly includes a first end and a second end. The first end is located within the hub assembly and the second end is engageable with the receiver hitch. The hubs are rotatably adjustable about the first end of the hitch insert assembly. The support wing assembly includes a first wing engageable with the arm of the first hub and a second wing engageable with the arm of the second hub. The bike rack also includes an integral locking member and a pair of independently moveable cradles on each wing. Each cradle includes a bike support member.
