Patent number: 12220870Abstract: A light polymerizable composition for use in the additive manufacturing of medical devices may include a first photo-initiator and a second photo-initiator. The first photo-initiator activates to initiate curing of the composition when exposed to light of a first wavelength in an additive manufacturing device and the second photo-initiator limits the transmission of the light of the first wavelength that activates the first photo-initiator in the additive manufacturing device. The second photo-initiator is activated to further cure the composition when exposed to a light of a second wavelength different from the first wavelength by activating the second photo-initiator to produce free radicals at a higher rate when exposed to the light of the second wavelength than when exposed to the light of the first wavelength.Type: GrantFiled: November 27, 2023Date of Patent: February 11, 2025Inventors: H. David Dean, Al Siblani, Eric J. Mott, John P. Fisher, Martha O. Wang, Antonios G. Mikos

Patent number: 5396939Abstract: A machine for making staves includes a first section and a second section with each section including components for cutting one side of a blank in a manner inclined to the blank's lengthwise axis. Conveyors on each section are equipped with lugs for propelling the blanks with each lug having a foot to support a lug engaged end of the blank against laterally applied loads imparted by wheel members. Additionally supporting each of the conveyed blanks on each section is a fence on each section with the lug foot and the fence serving to maintain the blank in a skewed position to present a displaced side edge to a cutter head. The fence on the second section additionally supports the blank against lateral loads applied in an opposite direction by wheels biasing the blank into fence and lug engagement to skew in an opposition direction. A cutter head on the second section of the machine completes shaping of the blank by cutting a second side edge inclined to the stave's lengthwise axis.Type: GrantFiled: September 21, 1993Date of Patent: March 14, 1995Inventors: John J.

Patent number: 4324561Abstract: A process and apparatus for pelletizing tree bark and other botanical material for use as an industrial fuel. A dryer burning fines from the final product is used to heat bark or other botanical material which is typically a waste product from lumbering or agricultural production. Once dried, the material is finely ground, preheated and forced through a pelletizing mill to create a pelletized product having a diameter of approximately 0.635 cm. The pellets are then cooled and leave the process. Several pelletizing mills are disclosed which are situated to trap the dried material against at least one die such that there will be a continuous, positive feed of material into the die. The resulting product may be substituted for coal as a heating source.Type: GrantFiled: July 24, 1980Date of Patent: April 13, 1982Assignee: NIPAC, Ltd.Inventors: John J. Dean, Lloyd M. Helzig
