Publication number: 20240174575Abstract: A device and a process for forming a monolithic substantially closed-porosity ceramic fluidic device having a tortuous fluid passage extending through the device, the tortuous fluid passage having a smooth interior surface, a material of the ceramic body having a continuous and uniform distribution of grains at least between opposed major surfaces of the ceramic body. The process includes positioning a positive fluid passage mold within a volume of binder-coated ceramic powder, pressing the volume of ceramic powder with the mold inside to form a pressed body, heating the pressed body to remove the mold, and sintering the pressed body. A relationship between a first stability characteristic of the volume of ceramic powder and a second stability characteristic of the mold prevents discontinuities in the pressed body after pressing and/or during heating.Type: ApplicationFiled: March 21, 2022Publication date: May 30, 2024Inventors: George Edward Berkey, Alexander Lee Cuno, James Scott Sutherland

Publication number: 20240157600Abstract: A module and process for forming a ceramic fluidic module (300) that includes a unified closed-porosity ceramic body (200) and a tortuous fluid passage (P) that extends through the body (200). The body (200) has a first mean density within a first layer (222) that is greater than a second mean density within a second layer (226). The first and second layers (222, 226) are axially serially arranged between opposed major surfaces (228, 229) of the body (200). The fluid passage (P) adjoins the first layer (222) of the body (200). The process includes pressing a first volume of ceramic powder (120) to form a pre-pressed body (150). A passage mold (130) is then positioned on the pre-pressed body (150). The pre-pressed body (150) and the passage mold (130) are then covered with a second volume of ceramic powder (125). The body (150), the mold (130), and the second volume of ceramic powder (125) are then pressed to form a pressed body (160).Type: ApplicationFiled: March 29, 2022Publication date: May 16, 2024Inventors: Alexander Lee Cuno, Thierry Luc Alain Dannoux, James Scott Sutherland

Patent number: 8699011Abstract: A method of absorption spectroscopy to determine a rapidly variable gas parameter. The method includes transmitting light from a synchronization light source to a synchronization detector. The transmitted light is periodically interrupted by a moving mechanical part between the synchronization light source and synchronization detector. The output from the synchronization detector is used to generate a repeating time signal having variable phase delay. This signal is used to control the timing of laser spectroscopy wavelength scans. Multiple spectroscopic scans may be repeated at multiple selected time signal phase delay and the results averaged for each phase. Apparatus for implementing the above methods are also disclosed.Type: GrantFiled: May 10, 2011Date of Patent: April 15, 2014Assignee: Zolo Technologies, Inc.Inventors: Henrik Hofvander, Bernard P Masterson, Andrew D Sappey, James Howell, David Owenby, Lee Sutherland, Michael J Estes

Patent number: 7310833Abstract: A lift is provided to facilitate access to swimming pools and spas. The lift includes a base and a mast extending therefrom. An arm pivotally connects to the mast. A seat assembly connects to the arm. An overhead support is positioned above the seat assembly. A first actuator moves the arm about the mast, thereby moving the seat assembly between raised and lowered positions, to bring the seat assembly out of and into a pool. A second actuator rotates the seat assembly relative to the base to position the seat assembly over the pool or deck. In use, the lift attaches to a pool deck, adjacent the pool, and a user accesses the seat assembly from the deck. The second actuator rotates about the base to position the user over the water. The first actuator lowers the seat assembly, and the user exits the seat assembly into the water.Type: GrantFiled: June 29, 2005Date of Patent: December 25, 2007Assignee: Spectrum Products, LLCInventors: John P.
