Publication number: 20240157532Abstract: Illustrative embodiments of impact tools with impact mechanisms rigidly coupled to electric motors are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism, an electric motor, and a control circuit. The impact mechanism may comprise a hammer and an anvil, the hammer being configured to rotate about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor may comprise a rotor that is rigidly coupled to the impact mechanism, the electric motor being configured to drive rotation of the hammer about the first axis. The control circuit may be configured to supply a current to the electric motor and to prevent the current from exceeding a threshold in response to the hammer impacting the anvil.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Inventors: Timothy R. Cooper, John J. Linehan, Edward Charles Eardley

Publication number: 20210395906Abstract: There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.Type: ApplicationFiled: August 24, 2021Publication date: December 23, 2021Inventors: Karl Maurer, John J. Cooper, JR.

Patent number: 11185838Abstract: There is disclosed an electrode array architecture employing continuous and discontinuous circumferential electrodes. There is further disclosed a process for the neutralization of acid generated at anode(s) by base generated at cathode(s) circumferentially located to each other so as to confine a region of pH change. The cathodes can be displayed as concentric rings (continuous) or as counter electrodes in a cross pattern (discontinuous). In this way reagents, such as acid, generated in a center electrode are countered (neutralized) by reagents, such as base, generated at the corners or at the outer ring.Type: GrantFiled: November 30, 2019Date of Patent: November 30, 2021Assignee: CustomArray, Inc.Inventors: Karl Maurer, John J Cooper, Jr., H Sho Fuji, Joseph Leonetti

Patent number: 5837047Abstract: This invention relates to heat cured binder systems comprising as separate Parts: Part I comprising (a) a soluble source of silica, (b) an alcohol, and preferably (c) a surfactant; and Part II comprising an alkali aluminate. The binder systems are mixed with a refractory to form a refractory mix. The resulting refractory mix is shaped and heated at an elevated temperature to form a cured refractory shape, particularly a preform. Heat is applied by warm air, baking in an oven, microwave, or preferably by hot-box equipment.Type: GrantFiled: December 11, 1996Date of Patent: November 17, 1998Assignee: Ashland Inc.Inventors: Helena Twardowska, John J.
