Patent number: 9119374Abstract: There is provided an absorbent composition for water-based liquids, wherein dusting normally associated with handling of powdered absorbent materials is significantly reduced. The composition can be an animal litter, such as cat litter. The composition is formed by mixing a filler with a de-dusting agent and spraying an aqueous slurry of a deodorizing agent onto the mixture. The mixture is then added to a water absorbing material such as clay to uniformly mix the deodorizing agent with the water absorbing material.Type: GrantFiled: February 6, 2012Date of Patent: September 1, 2015Assignee: Church & Dwight Co., Inc.Inventors: Dragomir M. Bracilovic, Lauren Ciemnolonski, Mike Kelly, Frederick Lawson, Joseph A. Paluzzi, Zbigniew Senk

Patent number: 9010273Abstract: The present invention is directed towards an absorbent composition and its method of production and use. More specifically, the present invention relates to an absorbent composition comprising a liquid absorbing material, at least one alkaline earth metal peroxide, and an acidic material. The acid maintains a high hydrogen peroxide release profile under acidic conditions, such that the composition is found surprisingly effective in mitigating fecal odor.Type: GrantFiled: October 1, 2010Date of Patent: April 21, 2015Assignee: Church & Dwight Co., Inc.Inventors: Steven T. Adamy, Lauren Ciemnolonski, Frederick Lawson

Patent number: 8273676Abstract: An animal litter such as a clay material is treated to reduce the bulk density thereof by contacting the clay material with an aqueous electrolyte solution and then heating at an elevated temperature. Substantial reductions in bulk density have been achieved without reducing the absorption capacity of the clay granule.Type: GrantFiled: April 17, 2008Date of Patent: September 25, 2012Assignee: Church & Dwight Co., Inc.Inventors: Robert Falcone, Steven T. Adamy, D. Mark Bracilovic, Frederick Lawson

Patent number: 8156896Abstract: The present invention is directed towards a clump recognition animal litter that enables a user to visually identify and dispose of all used litter portions from unused litter, regardless of clump size and clump location within the litter. The clump recognition animal litter comprises a clumping component and a color-indicating material. The litter clumps and displays a color in response to wetness.Type: GrantFiled: November 20, 2007Date of Patent: April 17, 2012Assignee: Church & Dwight Co., Inc.Inventors: Robert C. Wadams, Steven T. Adamy, Frederick Lawson, Patricia Pulido, Kenneth E. Kellar

Patent number: 8149014Abstract: An I/O driver has v/i characteristic control for maintaining a substantially flat output impedance response using a transmission gate configuration at an I/O output pad. The configuration includes a linear resistive element electrically connected at an I/O pad for limiting a processed data I/O signal, an active impedance element for receiving and processing the data signal, which comprises data represented by a series of voltage state transitions, and pull-up and pull-down array calibration words, for generating and outputting a processed I/O output signal to the resistive element to output a substantially flat v/i response at switching of the data signal.Type: GrantFiled: October 27, 2008Date of Patent: April 3, 2012Assignee: International Business Machines CorporationInventors: David Jia Chen, William Frederick Lawson, David William Mann

Publication number: 20090153216Abstract: An IO driver circuit incorporates an output stage control circuit that selectively configures an output stage for the IO driver circuit to operate as a thevenin termination whenever the IO driver circuit is receiving a signal from an input/output node to which the IO driver circuit is coupled. The output stage may include a plurality of branches, with each branch having a pull-up device and a pull-down device, and the output stage control circuit selectively activates the pull-up devices in a first subset of branches in the output stage while concurrently activating the pull-down devices in a second subset of branches, as well as while leaving the pull-up devices in the second subset of branches and the pull-down devices in the first subset of branches deactivated.Type: ApplicationFiled: December 12, 2007Publication date: June 18, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David Jia Chen, William Frederick Lawson

Publication number: 20090085635Abstract: A design for a high speed differential voltage level shifter circuit arrangement utilizes both PFETs and NFETs controlled by inputs to determine the state of the outputs, which minimizes or eliminates contention on internal nodes when switching from one state to another. As a result, the design minimizes the adverse affects of mismatched NFET and PFET device strengths, and facilitates usage at high frequencies and for level shifting to a range of output voltage levels. The design is also adaptable for use in level shifting to higher or lower output voltages.Type: ApplicationFiled: September 28, 2007Publication date: April 2, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David Jia Chen, William Frederick Lawson
