摘要： A present invention license reallocation system and method facilitates flexible and effective licensing distribution. The license reallocation system and method enables convenient movement of licensed information between hardware devices while ensuring appropriate compliance with license terms. An expired license indication is generated on license expiration. The expired license indication indicates that prior license keys associated with proprietary information are expired. Upon receipt of a valid expired license indication and expired license keys new license key(s) is issued presumably for a different hardware. A license serial number (LSN) that is both globally unique and mutable is utilized to generate license keys. In one embodiment, the license serial number includes system serial number (SSN) and an extension serial number (ESN). The global uniqueness of the SSN ensures that the tuple (SSN, ESN) is globally unique and the mutable but non-repeating nature of the ESN ensures that the tuple is allowed to change without repeating its value.
摘要翻译：本发明的许可证重新分配系统和方法有助于灵活和有效的许可分发。许可证重新分配系统和方法可以方便地在硬件设备之间移动许可信息，同时确保符合许可条款。在许可证到期时生成了过期的许可证指示。过期的许可证指示表明与专有信息相关联的先前许可证密钥已过期。在收到有效的过期许可证指示和过期的许可证密钥后，可能会为不同的硬件颁发新的许可证密钥。全局唯一和可变的许可证序列号（LSN）用于生成许可证密钥。在一个实施例中，许可证序列号包括系统序列号（SSN）和扩展序列号（ESN）。 SSN的全局唯一性确保了元组（SSN，ESN）是全局唯一的，并且ESN的可变但不重复的性质确保允许元组更改而不重复其值。

摘要： The invention relates to an electrode configuration of electrolysers using oxygen storage material to prevent oxidation of anodic active catalyst layer where oxygen storage material will be preferentially oxidised prior to anodic active catalyst. The inventions also relates to the use of hydrogen storage material with cathodic active catalyst to supply hydrogen to react with oxygen supplied from anodes when a reduction load is connected between the anode and cathode. One configuration utilises of individual layers containing oxygen and hydrogen storage materials, active catalyst layers, perforated current collectors, monopolar plates and a porous separator. A reduction load is used during operation of the electrolyser to convert metal oxides into pure metal by consuming oxygen from the electrolyser cell during stand by mode, shut down mode and intermittent operation, which will increase the durability of electrodes.
摘要翻译：本发明涉及使用储氧材料以防止阳极活性催化剂层氧化的电解槽的电极结构，其中储氧材料将在阳极活性催化剂之前被优先氧化。本发明还涉及当负极连接在阳极和阴极之间时，使用具有阴极活性催化剂的储氢材料供应氢气以与从阳极供应的氧气反应。一种结构利用包含氧和储氢材料，活性催化剂层，穿孔集电器，单极板和多孔分离器的各层。在电解槽操作期间，通过在待机模式，关闭模式和间歇操作期间从电解池中消耗氧而将金属氧化物转化为纯金属，因此在电解槽操作期间使用还原负载，这将增加电极的耐久性。

摘要： Class C fly ash may be activated with strong alkali to yield a novel, dense, quick-setting cement having unexpected properties. The setting time of the cement decreased as the pH of the activating solution increased. The microstructure and phase assemblage of the novel cement depended on the pH. Ettringite was absent beyond pH 14.30 (2.0N); a hexagonal plate-like crystalline form (stratlingite (gehlenite hydrate, C.sub.2 ASH.sub.8) and other compounds) became more abundant at higher pH. At higher pH the microstructure was characterized by high amounts of the plate-like crystalline phase and a dense matrix, due to higher reactivity of the glassy phase in fly ash. The novel cement will have uses in a number of areas, including fixation of hazardous wastes such as radioactive wastes, applications where rapid setting is desired, and formation of concrete in hot environments where ordinary Portland cements may tend to crack due to their heat of hydration.
摘要翻译： C级粉煤灰可以用强碱活化，产生具有意想不到的特性的新颖，致密，速凝的水泥。随着活化溶液的pH增加，水泥凝固时间减少。新型水泥的微结构和相组合取决于pH值。超过pH 14.30（2.0N），不含钙矾石; 在较高的pH值下，六边形板状结晶形式（str + E，uml a + EE堇青石（鹅卵石水合物，C2ASH8）等化合物）变得更加丰富。在较高的pH下，由于粉煤灰中玻璃相的反应性较高，微结构的特征在于大量的板状结晶相和致密基质。新型水泥将在许多领域使用，包括固定危险废物如放射性废物，需要快速凝固的应用，以及在热水环境中形成混凝土，普通硅酸盐水泥由于其水合热而易于开裂。
