Title: Improvements to sanding disks
Inventor: VAN OSENBRUGGEN ANTHONY ALFRED
IPC: B24D13/16
Filed: 1997-06-17
Granted: 2003-01-21
Abstract: Accessories for an angle grinder include a disposable rotary sanding disk having quite large shaped ventilating/viewing apertures, for use with a resilient backing plate also having shaped ventilating apertures. The apertures of one or both parts are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the sanding disk more resilience so that a greater area comes in contact with the work and the disk wears more evenly over its abrasive surface.

Abstract: When an external reset signal EXRST is asserted received by a reset unit (6), it is synchronised with an internal clock to produce an internal reset signal INRST, which is applied to a CPU (4) and other modules in the circuit to reset them. While the internal reset signal INRST is being applied to the CPU, the rate of a refresh signal being generated by a DRAM controller (7) for refreshing data in DRAM (3) is incresaed.  Then, when the external reset signal EXRST is disabled, a delayed reset signal DLYRST is generated and applied to the DRAM controller (7) so that it is reset. The CPU, being already reset, can then quickly reconfigure the DRAM controller and re-enable it to resume refreshing the DRAM (4), thus maintaining the data in the DRAM.
