Patent number: 9751088Abstract: The rotational speed of the drum of an ore mill may be controlled variably over time. By rotating the drum during a first time interval at high speed, especially hard or dense particles are broken up by tumbling. At the same time, the discharge characteristics of the mill are adversely affected. In a subsequent second time interval, the drum is rotated at a slower speed, and the material is discharged more effectively, whereas the tumbling movement inside the mill is not achieved. The combination of said different modes of operation within short time periods in continuous operation may improve both the comminution as a result of a tumbling motion of the material and also the discharge of the ground material. By regulating the rotational speed with different target values within short time windows, different requirements for the movement behavior of the material to be ground and for the discharge characteristics of the ground material can be simultaneously optimized.Type: GrantFiled: March 8, 2011Date of Patent: September 5, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Harald Held, Michael Metzger, Florian Steinke

Patent number: 9701040Abstract: An apparatus and method for distressing material, such as a board. The apparatus may include a cutter head supporting a blade, a guide member, and a flattening device. The flattening device and the guide member are positioned proximate the cutter head and on opposite sides thereof. In response to the cutter head and the surface of the material being brought into cutting contact and moved relative to each other, a resulting portion of the surface of the material is distressed. The flattening device maintains the proper vertical position of the cutter head and blade relative to the material and a material support as the material is being brought into cutting contact with the cutter head. The guide member levels warped material boards thereby bringing the board into proper elevation and engagement with the blade for cutting or scraping a top surface of the board. The material may be wood.Type: GrantFiled: February 10, 2014Date of Patent: July 11, 2017Assignee: AFI Licensing LLCInventors: Matthew S Myers, Brian W Beakler

Patent number: 9688091Abstract: A ring binder has housing including a central portion and lateral sides. Hinge plates are held between the lateral sides of the housing. Each of multiple rings includes at least one ring member mounted for movement with the hinge plates between closed and open positions. An actuator is mounted for pivotal movement relative to the housing and engageable with the hinge plates for opening rings. In one embodiment, the housing defines a stop engaged by the actuator upon arrival of the actuator at a terminal position when the actuator has opened the rings. The engagement between the surface of the actuator and the stop limits pivoting movement of the actuator relative to the housing in the opening direction beyond the terminal position. In another embodiment, the actuator is constructed for quicker response of the binder to movement of the actuator to open the rings.Type: GrantFiled: July 26, 2010Date of Patent: June 27, 2017Assignee: World Wide Stationery Mfg.
