Publication number: 20180099892Abstract: Process for removing peripheral portions such as bead regions of a glass sheet including a step of pushing the glass sheet in the peripheral portion using a pushing mechanism such as a pushing bar, and corresponding apparatus. As a result of the use of the pushing mechanism, the engagement completion time for suction cups, if used, are reduced significantly. A process without using suction cups is enabled with enhanced yield. The increased process stability and enlarged process window are particularly advantageous for processing glass sheets having high flexibility.Type: ApplicationFiled: December 13, 2017Publication date: April 12, 2018Inventors: Nicholas Dominic Cavallaro, III, Keith Mitchell Hill, Harry Joseph Reidy, Liming Wang, Zheming Zheng, Naiyue Zhou

Publication number: 20180065431Abstract: A method for hitching a rolled wagon or cargo system to a standard vehicle hitch allowing for the quick connection and securing to the transport vehicle. Used exclusively for a wagon or cargo load capable of raising the load itself before having the load lowered on the hitch receiver assembly. Conversely the hitch allows for the quick disconnect and unhitching from the transport vehicle by simply having the load lift itself off of the hitch to be disconnected.Type: ApplicationFiled: September 5, 2016Publication date: March 8, 2018Inventor: Darren Keith Mitchell

Publication number: 20180050712Abstract: An electric mechanical wagon to assist in transportation and hauling various items is disclosed. A removable wagon with a superstructure that can be easily attached to a standard vehicle receiving hitch insert for transportation by said vehicle. The wagon's ease of attachment to the vehicle allows for quick mounting and un-mounting of the wagon to be relocated to a desired location. The mounting and un-mounting of the wagon is facilitated by an electro-mechanical lift system within the wagon itself. This lifting system allows the wagon to raise high enough to be mounted to a receiver plate attached to the vehicle hitch receiver. When mounted the wagon wheels retract and stow into the wagon body allowing enough clearance for transport of the wagon.Type: ApplicationFiled: August 18, 2016Publication date: February 22, 2018Inventor: Darren Keith Mitchell
