Publication number: 20240097065Abstract: A method of fabricating a single-crystal silicon photovoltaic cell includes providing a single-crystal silicon wafer and a structural support member. The single-crystal silicon wafer has a first major surface and a second major surface. Each major surface extends along a major surface plane. The single-crystal silicon wafer has a thickness greater than 100 micrometers and a dimension greater than 50 mm. The method further includes mounting the structural support member to the first major surface or to the second major surface. The method further includes reducing thickness of the single-crystal silicon wafer to a thickness less than or equal to 100 micrometers while the single-crystal silicon wafer is mounted to the structural support member. The method further includes providing the first major surface with a diffusion and a metalization grid and providing the second major surface with a back surface contact.Type: ApplicationFiled: September 20, 2022Publication date: March 21, 2024Applicant: Semivation, LLCInventors: David Vaclav Horak, Peter H Mitchell, Mark Charles Hakey, William R.

Patent number: 8393192Abstract: A tooling assembly for scoring a can end is provided. First and second opposing tool members cooperate to create a depression in the can end, and to form a scoreline within the depression. A conversion press for converting a can end shell into a can end, and a method for scoring a can end are also provided. The method includes engaging a first side of the can end with a score knife, supporting at least a portion of a second side of the can end with a score anvil, depressing the can end into a cavity of the score anvil to form the depression, and forming the scoreline within the depression. The depression and scoreline are formed substantially simultaneous within the same tool station of the conversion press. A sealant, which is applied to the scoreline, forms a pool within the depression, thereby completely covering the scoreline.Type: GrantFiled: January 20, 2012Date of Patent: March 12, 2013Assignee: Stolle Machinery Company, LLCInventors: Craig A. McEldowney, Mark R. Mitchell

Patent number: 7472575Abstract: A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.Type: GrantFiled: July 13, 2007Date of Patent: January 6, 2009Assignee: Stolle Machinery Company, LLCInventors: Gregory H. Butcher, Kenneth F. Fultz, Mark R. Mitchell, David A. Stradling, Greg S. Williams
