Patent number: 6092668Abstract: A litter screening and separating machine including a storage compartment, a loader at one end of the storage compartment for picking up encrusted litter material from the floor of a chicken house, a conveyor including a pair of chains for moving the encrusted litter from the loader to the storage compartment. A baffle plate adjacent to and beneath the conveyor chain prevents contamination of the conveyor chain. Vibrator rollers adjacent the pair of chains for engagement with tabs on spaced links of each chain for vibrating the loading flights. Trap doors beneath the upper run of the conveyor may be opened to permit some of the material collected to fall back to the floor of the poultry house.

Patent number: 6092190Abstract: A method of reprogramming memory storing program instruction code for controlling operation of a microprocessor in which new data can be written to the memory by the microprocessor only in a write cycle and stored data can be read from the memory by the microprocessor only in a read cycle, the memory preventing the read cycle and said write cycle occurring at the same time is disclosed. The memory has first and second sectors for storing code, the first sector storing boot code for controlling operation of the microprocessor. The disclosed method includes the steps of erasing code stored in said second sector, writing new code including the boot code to the second sector, erasing the first sector, writing new boot code in the first sector preceded by an instruction to jump to said second sector and then rendering the jump instruction ineffective so that the next boot of the microprocessor will cause the microprocessor to be controlled by the new boot code in the first sector.Type: GrantFiled: January 30, 1997Date of Patent: July 18, 2000Assignee: Neopost LimitedInventor: Daniel John Lee

Patent number: 6068760Abstract: Catalyst particles are separated from the wax in a Fischer-Tropsch reactor by feeding a portion of the reactor slurry to a dynamic settler which does not require any pump. As the slurry flows down a pipe in the center of the settler, the slurry flows into the surrounding annular region at the bottom of the settler. The heavier catalyst particles settle down and are removed as the slurry at the bottom of the settler is recycled back to the reactor. The wax rises up in the annular section and this clarified wax is removed by a wax outlet pipe. In an embodiment with an expanded diameter section above the Fischer-Tropsch reactor an additional dynamic settler can be placed inside this section. The Fischer-Tropsch catalyst can be regenerated by purging the catalyst with an inert gas for a period of time and by treating the catalyst with naphtha.Type: GrantFiled: August 7, 1998Date of Patent: May 30, 2000Assignee: Rentech, Inc.Inventors: Charles B. Benham, Dennis L. Yakobson, Mark S. Bohn

Patent number: 6065883Abstract: A method and apparatus is disclosed for controlling energization of a take-up motor driving a take-up spool of used ink ribbon in thermal printing apparatus. Prior to a printing cycle, the take-up motor is energized to rotate the take-up spool until ternsion in the ink ribbon caused rotation of an ink ribbon supply spool. The take-up spool is then rotated a predetermined amount and resultant rotation of the supply spool is determined by sensing means. A function dependent upon the rotation of the supply spool is determined and used during subsequent operation of the apparatus to control energization of the take-up motor such as to wind the used riobbon onto the take-up spool with a desired amount of tension in the used ribbon.Type: GrantFiled: September 2, 1998Date of Patent: May 23, 2000Assignee: Neopost LimitedInventors: William James Herring, Daniel John Lee
