Filed: 1992-03-27
Abstract: The specification discloses apparatus and process for grinding particulate solid material in presence of no more than 10% by weight of water and involving means for introducing particulate solid material into a grinding chamber 4 having a perforated base 8 through which gas is introduced to provide an upward flow of gas passing through the particulate solid material and an impeller 42 rotating in the grinding chamber 4 to agitate the particulate solid material. The base 8 has a central imperforate area 10 which causes the gas to pass preferentially through the region near the walls of the grinding chamber 4. In addition, a horizontal baffle plate 17 having a central opening 18 is positioned in chamber 4 at a height above the perforated base 8 which is not greater than one half (say 33%) of the transverse width (diameter) of the chamber 4. The plate 17 is provided to prevent the bed of material from extending upwards to an undesirable degree near the walls of the grinding chamber 4. The grinding apparatus may be used in surface treating an inorganic material. In Figure 2, impeller 42 is rotated from below; gas is admitted through a conduit 48, and baffle 17 communicates with a frustro-conical chamber 26. The impeller 42 of Figure 1 is driven from above.

Title: A memory management system for preserving cache coherency
Inventor: HAMMOND GARY N
IPC: G06F12/12
Filed: 1992-08-07
Abstract: A memory management system for a computer preserves cache coherency between a segment descriptor cache and a data cache through an inclusion bit mechanism. In one embodiment, an inclusion bit 814 is set for a segment descriptor in the data cache 810 to associate It with a corresponding descriptor in the descriptor cache 820. Whenever a descriptor in the data cache with an inclusion bit set is altered, the entire descriptor cache is flushed. Furthermore, in the same embodiment, a valid bit 816 is set for a descriptor in the data cache which corresponds to one fetched from a descriptor table 800 to indicate their association. Whenever a descriptor in the descriptor table is modified, which has a valid bit set in the data cache, the valid bit is reset. And if the same descriptor with its valid bit reset has an inclusion bit set, then the entire descriptor cache is flushed. As such, the cache coherency among the descriptor cache, the data cache and the descriptor table is preserved. <IMAGE>

Title: Multiple reference video processing
Inventor: SOWERBY BRIAN MARK
IPC: G11B27/00
Filed: 1992-08-21
Abstract: For synchronising the operation of first and second video devices (eg. vcr) referenced by respective timecodes and operable at different video rates in response to first and second timing references where the first video rate is a m/n times the second video rate, a predetermined phase relationship is established between the first timecodes from the first video means and second reference signals for the second video means and then target timecodes for synchronising the second video device are derived from the first timecodes and the second reference signals. In a first embodiment second timing reference signals are generated with a fixed, repeatable phase relationship with respect to the first timecodes by resetting the timing of the second timing reference signals in response to a first timecode which, when divided by m, gives a predetermined remainder. In a second embodiment a phase relationship between internally generated first and second reference signals is determined and then the first video device is synchronised with the first reference signals. <IMAGE>

Title: Improvements relating to resin curing systems
Inventor: BATES DARREN
IPC: C08J3/24
Filed: 1995-07-08
Abstract: To control when a phenolic resin system will cure, the acid catalyst is chemically blocked so that at ambient conditions, although the catalyst is mixed in the resin matrix, it will not cure. Cure can be initiated by the application of heat which "unblocks" the catalyst to enable it to commence the cure. The invention has particular application to the placement of tubular liners impregnated with the resin in pipes or passageways where the liner is inflated into the pipe or passageway before curing of the resin and then curing can be effected at the installers convenience, which is of considerable advantage.
