An article transfer device includes: a guide movement mechanism for moving a first guide portion and a second guide portion independently along a first direction; and an interlocking mechanism for interlocking movement of the first guide portion and the second guide portion along the first direction with movement of an article supporting portion such that the article supporting portion is located midway between the first guide portion and the second guide portion in the first direction.

A machine and a method for transporting a liner into a grinding mill body wherein the machine includes a housing for insertion through an opening of the grinding mill body. The housing has a first end, a second end and a conduit in communication with the first end and the second end, and a conveying device for conveying the liner along the conduit between the first and second ends.

An apparatus including a first conveyor device including a first conveyor belt; a second conveyor device including a second conveyor belt; a movement device; and a mold device including a mold; wherein the first conveyor device is connected to the second conveyor device so that when the movement device moves the first conveyor device, the second conveyor device also moves with respect to the mold device; wherein the first conveyor belt moves independent of the second conveyor belt; and wherein the first conveyor belt and the second conveyor belt move independent from the movement device. The apparatus may further include a first and second dispensing devices configured to dispense first and second materials, first and second gate devices to control height, and a computer processor to control the various components and the resulting ratio of first material to second material in a processed slab.

Described is a checkout station with an adjustable height conveyor belt, and a motorized height adjustor that is used to level and adjust the height of the conveyor belt. The motorized height adjustor includes an adjustable height leg and a motor drive. The motor drive uses a motor to rotate a foot sleeve of the adjustable height leg. Rotating the foot sleeve adjusts the height of the adjustable height leg. Adjusting the height of the adjustable height leg adjusts the height of the conveyor belt of the checkout station. The motorized height adjustor can be coupled to sensors to automatically adjust the height of the conveyor belt.

A device for the transport of ceramic slabs (L), comprising: a pair of inner belts (2,3) and a pair of outer belts (4,5), parallel to the transport direction (x) and coplanar to a transport plane; wherein each belt is associated to respective supports (210,220,310,320,410,420,510,520); at least the front supports (210,310,410,510) are slidably associated to a front bar (6), arranged perpendicular to a transport direction (X) and parallel to the transport plane; a motor means, predisposed to activate the front bar (6) in rotation, so as to displace the front supports (210,310,410,510) along the front bar (6), in a perpendicular direction to the transport direction (X) and parallel to the transport plane.

A conveyor device includes at least three lift columns, a lower conveyor body, and an upper conveyor body. The upper conveyor body is adjustable in its height relative to the lower conveyor body. The lift columns project at least partially above the upper conveyor body without lengthwise supports acting in the transport direction.

An assembly includes first and second shafts and first and second sprockets. The first shaft has a first and second ends and a first longitudinal axis of rotation. The first sprocket is attached to the first shaft proximate the first end of the first shaft. The first sprocket rotates with the first shaft. The second shaft is spaced from the first shaft by a distance, the second shaft having a first end spaced from the first end of the first shaft by the distance, a second end spaced from the second end of the first shaft by the distance, and a second longitudinal axis of rotation substantially parallel to the first longitudinal axis of rotation. The second sprocket is attached to the second shaft proximate the second end of the second shaft. The second sprocket rotates with the second shaft. The distance is adjustable.

An adjustable auger assembly for a trencher including an auger housing and a position attachment assembly. The auger housing having a central auger tube having a first end and a discharge end opposite the first end. An auger shaft is positioned within the auger tube and is rotatable relative to the central auger tube. At least one material inlet is positioned one of at the first end and between the first end and the discharge end. The position attachment assembly has a first component member coupled to the trencher, and a second component member coupled to the auger housing. The first component member is movably positionable relative to the second component member, to, in turn, adjust the position of the auger housing relative to the trencher.

An apparatus including a first conveyor device including a first conveyor belt; a second conveyor device including a second conveyor belt; a movement device; and a mold device including a mold; wherein the first conveyor device is connected to the second conveyor device so that when the movement device moves the first conveyor device, the second conveyor device also moves with respect to the mold device; wherein the first conveyor belt moves independent of the second conveyor belt; and wherein the first conveyor belt and the second conveyor belt move independent from the movement device. The apparatus may further include a first and second dispensing devices configured to dispense first and second materials, first and second gate devices to control height, and a computer processor to control the various components and the resulting ratio of first material to second material in a processed slab.

A support assembly for a telescopic conveyor may be provided. The assembly may include at least two spaced apart bearings and a reservoir of hydraulic fluid, the bearings being coupled to the reservoir to impart force to and receive force from the hydraulic fluid. The reservoir may be configured to transmit force received from any one of the bearings to at least one other of the bearings by the hydraulic fluid. The assembly can distribute uneven loads amongst the bearings thereby maintaining contact between the bearings and the conveyor, and reducing wear on the bearings and associated components.
