A material transfer vehicle for transporting asphalt from a delivery truck to a paving machine includes a frame and a vehicle drive system. The vehicle also includes a turret that is rotatably mounted on the frame and a surge bin that is mounted on the turret. The surge bin has a front side and a rear side with a discharge opening therein. A truck-unloading conveyor is mounted on the frame. The truck-unloading conveyor has an inlet end, and an outlet end which is adjacent to the front side of th...

An asphalt spreader mounted on its own ground supporting wheels including driven wheels which are power operated by means of a chain driven from a hydraulic motor operated by a pump driven by an engine mounted on the asphalt spreader. The asphalt spreader includes a heavy steel structure frame having a platform at the rear on which the operator stands and having a large movable asphalt bed separated from the operator's platform by a large vertical wall. The bed is selectively operable to be rais...

A paver (1) with a chassis (2) at the front in the paving direction, with a hopper (11) for receiving material to be paved and, at the rear, with a floating screed (5), two centrally arranged longitudinal conveyor devices (9,10) guided through a shaft (8) being provided between the hopper (11) and a distributor auger (7) located in front of the screed (5) in the paving direction, the hopper (11) being open relative to the longitudinal conveyor devices (9,10) and an additional conveyor device (33...

A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.

A paver machine for applying paving material to narrow paths is disclosed. The machine includes a storage hopper and frame elevated above a roadbed by at least three wheeled unit members. A free-floating screed assembly located beneath the hopper and pivotally attached to the frame applies a paving material matte to the roadbed as the paver machine is moved along by a front end loader or the like.

Curing agents for aqueous epoxy resin dispersions obtained by reaction of an adduct (A) of at least one polyepoxide (A.sub.1) and at least one polyalkylene polyether polyol (A.sub.2), it being possible for the adduct (A) to be modified with a secondary amine (A.sub.3) if appropriate, with I. a reaction product of an amine (B) and an epoxide (C) or II. an amine (B) and subsequent reaction with an epoxide (C), the amount of amine (B) being chosen such that the H atoms on the nitrogen are present i...

A developer for electrostatography containing a positive charge controlling agent comprising fumed silica particles treated with a silane coupling agent or titanate coupling agent and controlled to an appropriate degree of hydrophobicity has a stable and sharp distribution in amount of positive triboelectric charges under a variety of conditions including higher temperature-higher humidity or lower temperature-lower humidity conditions. This developer is useful particularly in an electrophotogra...

An attachment for a skid steer loader for use in performing road widening and shouldering jobs in small areas such as bike paths, driveways and cul de sacs. The attachment includes a compact frame adapted to support a hopper, a conveyor system, a spreader system, a spreader system angular adjustment, a hydraulic system, at least one wheel, at least one contact roller, and a universal mounting plate. The hydraulic system receives its power from the hydraulic system of, for example, a skid steer.

An apparatus for treating a pavement surface with a plurality of layers in a single pass, including: a chassis having a forward end and a rear end; a plurality of rolling means spaced longitudinally along the chassis for supporting the chassis so it can roll along a particular direction of advance; a powerplant for moving the chassis along the direction of advance; a first storage tank mounted on the chassis for containing bituminous sealant; a second storage tank mounted on the chassis for cont...
