Abstract: A bucket elevator adjustable guide system for efficiently transferring and dispensing particulate material from a bucket elevator includes a head housing connected to the bucket elevator, an adjustable guide member disposed therein, an extendable and retractable adjustment member connected to the guide member, a remotely controllable drive unit coupled to the adjustment member, and a remote control. The head housing receives buckets of particulate material to be dispensed from the bucket elevator. The guide member extends in a curved arc over the buckets to engage and guide discharged particulate material into a discharge chute. Remote controls enable the drive unit to be manually or automatically controlled to cause the adjustment member to extend or retract to adjust the position and configuration of the guide member and affect the transfer and dispensing of the particulate material without physically accessing the adjustment member.

Abstract: A charging device for bulk material comprises a rotor having a substantially vertical axis of rotation a first drive for rotating the rotor and a chute supported by the rotor so as to be rotated with the latter. The chute can be rotated about its longitudinal axis. Its concavely curved sliding surface has a width that is diminishing from the top end to the bottom end of the chute, so that it is possible to vary the location where bulk material sliding down the chute channel leaves the latter by rotating the chute about its longitudinal axis.

Abstract: A snow removing machine has an auger for plowing and collecting snow, a rotatable blower for throwing snow collected by the auger, and a shooter for guiding the snow thrown by the blower so that the snow reaches a selected point. The blower has a central shaft part and blades extending radially outwardly from the shaft part. Each of the blades has one pair of laterally spaced guide walls projecting from a distal end portion thereof in a direction of rotation of the blower. The pair of guide walls for each of the blades extend divergently from each other towards a distal end of the blade.

Abstract: For handling elongate and flat workpieces flowing in a manufacturing line, two arrangements are disclosed, one being an arrangement including a workpiece posture changing device which changes the posture of each workpiece at the time when the workpiece is transmitted from a first conveyer to a second conveyer, and the other being an arrangement for bundling the workpiece flowing in the manufacturing line.

Abstract: An endless belt conveyor including an independently supported first support pulley vertically and laterally displaced from a second support pulley. An endless belt including bulk material carrying compartments entrained around the first and second support pulleys and which is engaged by the full width of said support pulleys. The endless belt includes a radius of curvature near the top of the vertical run of a predetermined size such that the bulk material carried in the endless belt is not expel due to centrifugal force. A portion of the endless belt entrained over the first support pulley has a radius of curvature of a predetermined size such that the material carried in the endless belt is expelled due to centrifugal force.

Abstract: An apparatus for mounting on the back of a dump truck or the like to distribute material discharged from said truck to a variably selected position is disclosed wherein a chute assembly is connectable to the tailgate of the dump truck and provides a range of movement of the apparatus in a vertical direction through pivotal movement about a horizontal axis and a range of movement of the apparatus in a horizontal direction through a swing ring. The apparatus incorporates an endless conveyor having a downwardly deflected portion to receive material from the chute assembly and convey the material to a discharge opening for projection to a selected location. A constraining member restricts the material to the central portion of the conveyor to minimize the spreading of the material being discharged from the conveyor.

Abstract: For the continuous melting of silicon granulate for a band drawing method, a melt reservoir in communication with the melt crucible based on the principle of communicating vessels, is provided in the form of a thermally insulated, annular crucible in whose center axis a rotary plate to be centrifugally accelerated is arranged, the speed thereof being continuously varied. Two pipe parts connected to one another at an angle between approximately 45.degree. to about 90.degree. are secured on the rotary plate, the one, vertical pipe part thereof serving as admission in the rotational axis and the other pipe part thereof forming the acceleration path for the granulate particles in the direction toward the annular melt crucible. On the basis of this arrangement, a uniform delivery and melting of the granulate particles in the melt surface is achieved and, thus, a continuous silicon band drawing with uniform layer thickness is enabled. The arrangement is used in the manufacture of silicon bands for solar cells.

Abstract: A reclaiming wheel which has a pair of annular members mounted on an axle. A flexible belt is fitted between the peripheries of the annular members around part of their circumference. Scoops are attached to one or both of the annular members, projecting both axially and radially. As the wheel is rotated about the axle the scoops direct material to be reclaimed through openings in the annular member to which they are attached into the interior of the wheel. The material is held against the belt by centrifugal force and moves with the belt and wheel until it reaches the point at which the belt separates from the wheel. The material is then thrown from the wheel onto a conveyor.
