Patent CA-2225144-A1 (CA)
Inventor: PHINNEY ROBIN
IPC: C05G5/30
Filed: 1997-04-09
Abstract: An apparatus and method for uniform granulation is disclosed. The method involves the use of an initial feedstock having particle size of -150 mesh and 90 % or greater particle size of 200 mesh. The feedstock may be contacted in a pan granulator which includes a minor amount of nucleating material of about -35 mesh. Binder is introduced into the pan granulator to progressively layer the feedstock material onto the nucleating to form a final product having a size distribution -8 mesh to +4 mesh. The method is designed to be interruptible and is particularly useful for forming granules having a plurality of layers of differing material. The method has marked improvement over the prior art methods since a particularly fine granule can be formed in a relatively expedient process to result in a granule having high commercial value and high break strength. These factors are achievable in addition to 100 % product usage with no waste.

Patent CA-2233789-A1 (CA)
Inventor: MES IAN
IPC: G11C7/10
Filed: 1998-04-01
Abstract: An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage. The asynchronous control signals are generated within the chip and are optimized to the different latency stages. Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it.

Abstract: First and second (especially NTSC and DTV) component television signals that respectively occupy first and second immediately-adjacent channels are simultaneously transmitted. These first and second component television signals have respective first and second radiation patterns that are different from each other. A main antenna broadcasts a composite signal including the first and second component television signals according to a composite radiation pattern. At least one auxiliary antenna transmits a tapped component signal derived from only one (NTSC or DTV but not both) of the first and second component television signals. The auxiliary antenna defines a component radiation pattern that, when added to the composite radiation pattern defined by the main antenna, results in a combined radiation pattern in which the first component television signal has a radiation pattern that is different from the radiation pattern of the second component television signal. In this manner, the NTSC and DTV signals transmitted from the same location may be steered differently from each other. Further, two separate auxiliary antennas for respective NTSC and DTV component television signals may be provided, to provide enhanced steering.
