Publication number: 20240088696Abstract: Aspects of a charging system may involve altering the duty cycle of the shaped charge signal over a period of time to alter an average current supplied to an electrochemical device while maintain the maximum current of the charge signal. For example, the average current of the charge signal used to charge a battery may be adjusted by varying the duty cycle or peak current of the shaped charge signal, and may be based, in some instances, on the state of charge, temperature, and/or impedance of the battery. In some instances, control over the average or total current of the charge signal is constrained by the maximum current that the system can supply, such that altering the duty cycle of the charge signal provides control over an average current of the charge signal without needing to supply additional current sources.Type: ApplicationFiled: September 14, 2023Publication date: March 14, 2024Inventors: John Richard Howlett, III, Garrett P. Wheeler, Daniel A. Konopka, Ryan Wu

Patent number: 6852181Abstract: A method for cold forming a flattened, end-threaded rod into a U-bolt answers the need for high-strength steel rods that can be bent into flattened U-bolts by spring and suspension repair facilities or the like. By controlling the amount of work put into the end-threaded flattened rod during bending, it is possible to manufacture a flattened, end-threaded rod from a high-strength steel that can be successfully cold bent into a U-bolt. The amount or degree of flattening and the radius of the U-bolt are variables which applicant controls to successfully cold bend a high-strength steel flattened rod into a U-bolt. Therefore, the spring and suspension repair facility avoids the need to heat the flattened rods for warm forming and, instead, can maintain an inventory of end-threaded and flattened rods for cold forming into flattened U-bolt comply with OEM designs when modifying or repairing vehicles.Type: GrantFiled: October 22, 2002Date of Patent: February 8, 2005Assignee: Consolidated Metal Products, Inc.Inventor: Robert P.

Patent number: 5847013Abstract: Disclosed are methods of producing super absorbing polymeric networks of polyaspartates from crosslinked polysuccinimide. In one preferred method aspect, polysuccinimide is first reacted with an organic crosslinking agent, preferably an organic base containing at least two primary amine groups to form crosslinked polysuccinimide. The crosslinked polysuccinimide is then hydrolyzed to a polymeric network of polyaspartate which demonstrates super absorbing capability in water and in saline solution. Alternative method aspects are disclosed in which super absorbing polymeric networks of polyaspartates are produced in a single reaction vessel by sequentially crosslinking polysuccinimide with organic crosslinking agent in an aqueous reaction mixture and then hydrolyzing the reaction product to produce a polymeric network of polyaspartate.Type: GrantFiled: March 17, 1997Date of Patent: December 8, 1998Assignee: Donlar CorporationInventors: Robert J.

Patent number: 5618495Abstract: The invention relates to colorimetric titration method, a titrator and colorimeter device. The titrating apparatus comprises radiant energy means for producing radiant energy. The device includes means for modulating an amplitude of an intensity of the radiant energy at a modulation frequency. The radiant energy is partially absorbed by an adjacent solution within a sample beaker having a color indicator dissolved therein. Radiant energy focusing means focuses the modulated radiant energy transmitted through the sample and beaker on radiant energy detection means. The radiant energy detection means produces a transmitted signal wherein an intensity of the transmitted signal is directly proportional to the intensity of transmitted energy. Filtering means filters the transmitted signal, such that a center frequency of the filtering means matches the modulation frequency of the radiant energy means.Type: GrantFiled: April 5, 1995Date of Patent: April 8, 1997Inventors: Andrew S. Mount, Douglas Paul, Alfred P. Wheeler

Patent number: 5545336Abstract: The present method is capable of completely neutralizing the aldehydes in aldehydic waste waters within about 15 minutes and of producing a non-toxic waste water which then can be disposed of without fear of contamination of drain lines, etc. The method is carried out by contacting aldehyde-containing waste water with a sufficient amount of sodium pyrosulfite to completely neutralize the aldehydes in the waste water within about 15 minutes to non-toxic substances. The contacting is initiated without first adjusting the pH of the waste water and is maintained during the treatment period with agitation of the waste water being treated to assure full neutralization of all parts thereof. The sodium pyrosulfite and its reaction products are non-toxic. No hazard label is required for the sodium pyrosulfite, in contrast to certain conventional waste treating chemicals. The sodium pyrosulfite is a white crystalline powder easily stored, handled, weighed out and used without danger.Type: GrantFiled: October 3, 1995Date of Patent: August 13, 1996Inventors: Steven P.
