    • Nanometer-sized non-superconducting particulates in superconductive REBCO films, where RE is a rare earth metal, for flux pinning enhancement and a method of forming are disclosed. A target with a second phase material sector portion and a superconductive material portion is used in a pulse laser deposition process to form films on substrates according to the present invention. The films consist of 10-20 nm-sized precipitates. In a 0.5 μm thick film, a transport critical current density (Jc)>3 MA/cm2 at 77K in self-field was measured. In one embodiment, magnetization Jc at 77 K and 65K showed significant improvements in a composite YBCO films with fine precipitates produced according to the present invention as compared to non-doped (standard) YBCO films (>10 times increase at 9 T, 65 K).

    • Scheduling circuitry, for use for example in an ATM network unit to schedule cell transmissions, includes a master calendar (1) for holding entries corresponding respectively to events (cell transmissions) that are to occur within a preselected master-calendar scheduling range (SR), and a slave calendar (12) for holding entries corresponding respectively to events that are to occur beyond that scheduling range. When an event is to be scheduled, calendar control circuitry (24) makes an entry corresponding thereto in the slave calendar (12) if the interval between a current time and a desired scheduling time for the event exceeds said scheduling range. The entry in the slave calendar includes timing information representing the desired scheduling time. The calendar control circuitry monitors the entries in the slave calendar (12) and causes an entry therein whose corresponding event becomes within the scheduling range to be transferred to the master calendar (1). Such scheduling circuitry can deal effectively with events that are to be scheduled at widely disparate intervals (very short and very long) without requiring the calendars to be large and without complicated processing of the calendar entries.
    • 用于例如在ATM网络单元中调度小区传输的调度电路包括主日历(1),用于保存分别对应于在预先选择的主日历调度范围(SR)内发生的事件(小区传输)的条目, ,以及从日历(12),用于保存分别对应于超出该调度范围的事件的条目。 如果要安排事件,则如果事件的当前时间和期望调度时间之间的间隔超过所述调度范围,则日历控制电路(24)在从日历(12)中进行与其对应的条目。 从日历中的条目包括表示所需调度时间的定时信息。 日历控制电路监视从属日历(12)中的条目,并使其中对应事件变成调度范围内的条目传送到主日历(1)。这样的调度电路可以有效地处理将要发生的事件 安排在不同的时间间隔(非常短和非常长),而不需要日历大,并且没有日历条目的复杂处理。

    • A method is disclosed for removing impurities from an elastomer intended for medical or pharmaceutical use, which includes a step of performing a first solvent extraction process on the elastomer by contacting the elastomer with a first extracting solvent in a non-supercritical state to substantially remove impurities from the elastomer, thereby leaving a residue of said first extracting solvent in the elastomer. The elastomer is there after subjected to a second solvent extraction process, by contacting the elastomer with a second extracting solvent, which is a supercritical fluid or a mixture of super critical fluids, in order to remove substantially reduce the concentration of the residue of the first extracting solvent remaining in the elastomer after the first solvent extraction process.
