Title: Process for making open pored sintered glass having a large open pore volume, which is particularly suitable as a filter for liquids and gases at high flow rates
IPC: B01D39/20
Filed: 1987-10-17
Abstract: Open-pored sintered glass is produced by conventional processes but, at pore volumes of more than 60%, the resulting tensile bending strengths are too low for an application as a filter medium. A further disadvantage for filtration is the wide distribution of the pore size and the structuring of the internal surface of the pores. The novel process is intended to provide open-pored sintered glass with large open pore volume, high tensile bending strengths and good flow rates. 
<??>In this process, starting granules of finely granulated glass powder, coarsely grained salt powder and binder are first prepared. 5 to 20% by weight of fine-grained glass powder is then added to these starting granules and this mass is subjected to shaping. The shaped product as formed is heated to the sinter temperature of the glass and sintered, and the salt is then washed out of the sintered glass. 
<??>Production of open-pored sintered glass for filters.

Title: Pipelined data-processing apparatus
IPC: G06F11/00
Filed: 1989-11-22
Abstract: A pipelined data processing system comprises a 
series of pipeline stages through which instructions 
pass sequentially. If an error associated with a 
particular instruction (e.g. an illegal instruction) is 
detected, a Mayday signal is produced. This does not 
become active immediately. Instead it is passed down the 
pipeline along with the instruction that caused it, and 
becomes active only if that instruction attempts to 
terminate at the end of the pipeline. When the Mayday 
becomes active, it causes an interrupt to a diagnostic 
processor. If, on the other hand, the instruction that 
caused the Mayday is aborted, or does not attempt to 
terminate, then the Mayday is discarded and does not 
become active. This prevents unnecessary diagnostic 
actions.
