    Abstract: A window actuator for a casement window has an actuator housing having a generally channel shaped receptacle portion defined by a rear wall, a front wall generally parallel to the front wall, and two end walls spaced to form therebetween a hollow interior with an open top surrounded by an outwardly extending peripheral flange and a base plate extending from the rear wall beyond the open top for mounting on a window frame. A worm housing is connected to and extends outwardly from the front wall of the housing and holds, by a plastics locking member threaded into the worm housing, a worm which is rotated by a manually actuable crank to drive a rotatable wheel mounted within the hollow interior. The wheel has an outwardly extending portion connected by an arcuate pivotal link to an actuator arm pivoted at its inner end on the base plate and arranged so that in the extended position of the arm, the link goes overcenter against a stop on the housing. The wheel is mounted on a mounting pin by an integral plastics bearing member including an annular sleeve portion projecting through the opening and having an inner surface surrounding the pin and an outer surface engaging the opening in the wheel, a planar plate portion lying between and in contact with one side surface of the wheel and one of the front and rear walls and a locating portion for engaging the wheel to prevent relative rotation between the wheel and the bearing member.

    Abstract translation: 用于平开窗的窗执行器具有致动器壳体，该致动器壳体具有由后壁，大体上平行于前壁限定的大致通道形状的接收部分，以及两个端壁间隔开并形成中空的内部，其中敞开的顶部包围 通过向外延伸的周边凸缘和从后壁延伸超过开口顶部的底板，以安装在窗框上。 蜗杆壳体连接到壳体的前壁并从壳体的前壁向外延伸，并且通过螺纹连接到蜗杆壳体中的塑料锁定构件保持一个蜗杆，该蜗杆由可手动致动的曲柄旋转，以驱动安装在中空内部的可旋转轮 。 车轮具有向外延伸的部分，该部分通过弧形枢转连杆连接到致动器臂，该致动臂在其内端枢转在基板上并且布置成使得在臂的延伸位置中，连杆相对于壳体上的止挡件过度偏心。 车轮通过一体的塑料轴承构件安装在安装销上，所述整体塑料轴承构件包括突出穿过开口的环形套筒部分，并且具有围绕销的内表面和与车轮中的开口接合的外表面， 与车轮的一个侧表面和前壁和后壁之一接触，以及用于接合车轮的定位部分，以防止车轮和轴承构件之间的相对旋转。

    Abstract: A memory device is placed in a mode that redefines the command set used to control the memory device. This may occur either in anticipation of the memory system falling out of calibration, or after it has already fallen out of calibration. The redefined command set is designed such that it may be reliably received by the memory device at the specified rate even if the memory system has fallen out of calibration. The redefined command set is then used to issue command(s) to recalibrate one or more communication links such that they can exchange data, commands, and/or addresses at a specified rate. After recalibration, the memory device is returned to responding to the original command set.

    Abstract translation: 存储器件被放置在重新定义用于控制存储器件的命令集的模式中。 这可能发生在预期的存储器系统脱离校准，或者在它已经脱离校准之后。 重新定义的命令集被设计成即使存储器系统已经脱离校准，也可以以指定的速率被存储器件可靠地接收。 然后，重新定义的命令集用于发出命令以重新校准一个或多个通信链路，使得它们可以以指定的速率交换数据，命令和/或地址。 重新校准后，内存设备将返回以响应原始命令集。
