A masonry block that is produced from a workpiece that is split in a block splitting assembly which uses any of a variety of projections to supplement or replace the action of the splitting blade in splitting and dressing the workpiece. The slide is used for locking the rail-mounted device on an attachment rail, wherein the slide has an attachment device for captive attachment of the slide to the rail-mounted device. The coupling member is operable to releaseably and interchangeably couple one of a selected blank member and a cold plate to the heat sink in response to a cooling requirement of the heat sink. The invention further relates to the inbred and hybrid genetic complements of plants of variety CV581972. For a failover involving an order-sensitive dataset or application, a mechanism is provided to detect order inconsistencies between a first set of data and a second set of data, in which the first set of data corresponds to a first connection established before the failover and the second set of data corresponds to a second connection established after the failover. Therefore, in another embodiment the front side has a light color border with a dark central area, and the dark central area will receive the graphic impression.
