Title: Removing sludge from collected combustion fume washing - using inclined enclosed worm feeding with stoppages to permit drainage
Inventor: FUELLEMANN JOERG
IPC: B01D21/24
Filed: 1989-12-01
Abstract: Sludge-bearing washing water from combustion fumes cleansing plant, e.g. in power stations or refuse incinerators, is collected in a tank and constantly stirred to cause agglomeration of small particles. Sludge is removed from the tank floor by the lower end of a screw conveyor (31) rising in an enclosing tubular housing (27), and driven by an upper end motor (15). Conveyor feed is only intermittent, providing intervals between the movements during which water can drop back towards the tank (11). From the top of the screw, made esp. of stainless steel strip, the part dried sludge lumps (13) drop into a collector. To avoid the screw being blocked, the turns are only attached to the core at every tenth layer, providing internal flexiblity. Pref. the lower end of the conveyor casing is somewhat belled to aid entry. USE/ADVANTAGE - Esp. for relatively small capacity plant. The relatively dry sludge is easily disposed of.

IPC: G06F9/06
Filed: 1990-08-25
Abstract: An apparatus and method for loading BIOS stored on a direct access storage device (62,66) into a personal computer system (10). The personal computer system (10) comprises a system processor (26), a system planar (24), a random access main memory, a read only memory (36), and at least one direct access storage device (62,66). The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and the direct access storage device (62,66) to read in a master boot record into the system (10) from the direct access storage device (62,66). The master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system (10) configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment (120) of the master boot record. The executable code segment (120) confirms that the system configuration has not changed and loads in the remaining BIOS portion from the direct access storage device (62,66) into random access memory (32). The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory (32). BIOS executing in random access memory (32) then boots up the operating system to begin operation of the personal computer system (10).
