  • Patent number: 8936145
    Abstract: The invention relates to a material conveyor system (1) for a road paver and feeder. The material conveyor system (1) comprises a material hopper (2), which comprises a first and a second hopper half (3, 4), a main conveyor device (5), which defines a main conveyor flow and which runs between the first and the second hopper halves (3, 4), and conveying screws (6, 7), which define a transverse conveyor flow and which are arranged in the hopper halves (3, 4). The material conveyor system (1) is characterized in that the conveying screws (6, 7) can be operated independently of the main conveyor device. The independent operation of the conveying screws (6, 7) and the main conveyor device (5) makes it possible to achieve improved homogenization of the mixing temperature of the paving material.

  • Patent number: 8851269
    Abstract: The present invention relates to a method of conveying and selectively discharging food products by providing a feeding system. The feeding system (14) comprises an inlet end (20), an outlet end (22), a receptacle (24) below the outlet end, a determination unit at the outlet end (22) and a feeder (18) for conveying the food products from the inlet end to the outlet end. When no food product is present at the outlet or in the receptacle (24), the food products are conveyed at a first average velocity. When a food product is present at the outlet end (22) and no food product is present in the receptacle (24), the food products are conveyed at a second average velocity. The second average velocity is lower than the first average velocity. When the food product is leaving the outlet end or is received within the receptacle (24), the feeder (18) is stopped until the individual food product has left the receptacle.

  • Patent number: 5871619
    Abstract: A discharge system for a destructive distillation apparatus wherein the discharge solids act as plug to avoid the unwanted flow of product gas or ambient air therethrough while effectively discharging finely divided, disperse solids material from a continuously operating distillation apparatus. The use of a positive displacement two-stage auger having close clearance between the auger and auger cylinder wall, combined with an open section within the auger cylinder where a sealing material plug forms, results in improved sealing of the inventive system from unwanted transfer of gases. The hot, disperse, and finely divided solids exiting a distillation apparatus, such as carbon black formed from the distillation of automobile tire chips, is effective in the formation of a seal plug.

  • Patent number: 5714043
    Abstract: A combination liquid seal and spiral auger conveyor feeding system which provides both a liquid seal, effective under normal operating conditions, with a sealed spiral auger conveyor, which is effective to seal against the surge flow of distillation gases back through the feeding system. This is attained while providing for a reliable, continuous flow of solid bulk material such as rubber tire chips to a reactor or distillation unit. A bulk feeding system having a partially submerged inclined spiral auger conveyor is provided, communicating at its base with a liquid reservoir so as to form a liquid seal within the combined apparatus. Solid bulk material is introduced to the upper end of the liquid reservoir above the liquid level where it descends by the action of gravity into the liquid and sinks to the bottom of the reservoir to by picked up by the partially submerged rotating auger conveyor and elevated thereby.
