Patent CA-2028272-C (CA)
Inventor: HESELIUS LARS
IPC: E04C2/292
Filed: 1989-12-14
Granted: 2001-02-06
Abstract: The invention relates to a longitudinal laminate board (1) of mineral wool to be used as a core of a sandwich element having surface layers preferably of thin sheet metal on each side. The laminate board consists of adjacently disposed rods (2) whose fibre plane form an essentially right angle to the plane of the laminate board. The rods are jointed within the laminate board, but the joints (3) are prepared so as to eliminate their weaken-ing influence on the board. This has been achieved by matching the shape of the jointed end surfaces and connecting them. The end surfaces may be glued, compressed, form a finger joint, etc. in order to increase the strength of the joint. The invention also relates to a method for manufacturing the sandwich element. Having been cut from a mineral wool board, the rods are rotated (IIIa) 90°  and assembled (Va) with end surfaces facing each other into rods, are cut to a length equalling the one of the laminate board and are assembled into a laminate board onto which the surface layers are applied during lateral compression.

Patent CA-2059143-C (CA)
Inventor: MIYAO TAKESHI
IPC: G06F11/16
Filed: 1992-01-10
Granted: 2000-05-16
Abstract: A computer system has a plurality of processing units connected via one or more system buses. Each processing unit has three or more processors on a common support board and are controlled by a common clock unit. The three processors perform the same operation and a fault in a processor is detected by comparison of the operations of the three processors. If one processor fails, the operation can continue in the other two processors of the processing unit at least temporarily, before replacement of the entire processing unit. Furthermore, the processing unit may have a plurality of clocks within the clock unit, with a switching arrangement so that the processors normally receive clock pulses from a main clock, but receive pulses from an auxiliary clock if the main clock fails. Switching between the main and auxiliary clock involves a comparison of the pulse duration from the clocks. Additionally, a plurality of cache memories may be connected in common to the processors so that failure of one cache memory permits the processing unit to continue to operate using the other cache memory. Coherence of the contents of the cache memories may be achieved by direct comparison, and a comparison method can also be used to invalidate data in an internal cache memory of a processor which differs from that in the external cache memory.    Coherence of protocols may also ensure that data in caches of the different processor units are always correct.
