    • A system and method for determining approval of a multi-currency transaction between a customer and a merchant over a network. The system includes a customer computer which is connected to a communication network, a merchant computer which is connected to the communication network, and a server connected to both the customer computer via the communication network and to the merchant computer via the communication network. The customer computer includes a first set of data which contains an amount the customer is willing to pay the merchant for a product in a first currency. The merchant computer includes a second set of data which contains a product price at which the merchant agrees to sell the product in a second currency. The server receives the first set of data and the second set of data. The server then converts the amount in the first currency into a converted amount in the second currency. The server approves the transaction if the converted amount in the second currency is within a risk range of the product price in the second currency in accordance with current exchange rates. Once the transaction is approved, the approving entity may settle the transaction at its discretion thereby bearing the risk associated with currency exchange. The parties, however, incur no risk. The customer will pay be amount in the first currency and the merchant will receive the price in the second currency. These are values known and agreed to by the parties at the time of the transaction.
    • 一种用于确定通过网络的客户和商家之间的多货币交易的批准的系统和方法。 该系统包括连接到通信网络的客户计算机,连接到通信网络的商家计算机,以及经由通信网络与客户计算机连接的服务器,以及经由通信网络与商用计算机连接的客户计算机。 客户计算机包括第一组数据,其包含客户愿意以第一货币为商品支付商品的金额。 商业计算机包括第二组数据,其包含商品同意以第二种货币销售商品的商品价格。 服务器接收第一组数据和第二组数据。 然后,服务器将第一货币中的金额转换为第二种货币的兑换金额。 如果第二种货币的转换金额符合当前汇率的第二种货币的产品价格的风险范围,服务器将批准该交易。 一旦交易获得批准,批准实体可以自行解决交易,从而承担与货币兑换相关的风险。 但是,各方不承担任何风险。 客户将支付第一货币的金额,商家将收到第二种货币的价格。 这些是当事人在交易时已知和同意的价值。

    • A process is disclosed for the production of low viscosity, high viscosity index liquid lubricant in high yield by the thermally-induced cleavage or pyrolysis of higher molecular weight oligomers of 1-alkenes. Further, it has been discovered that the reduced viscosity lubricants produced by pyrolysis of higher viscosity 1-alkene oligomers retain the superior characteristics of high viscosity index and low pour point of the starting material.The process comprises contacting C.sub.6 -C.sub.20 1-alkene feedstock with reduced valence state chromium oxide catalyst on porous silica support under oligomerizing conditions in an oligomerization zone whereby viscosity, high VI liquid hydrocarbon lubricant is produced having branch ratio less than 0.19 and pour point below --15.degree. C.; passing said high viscosity liquid lubricant through a pyrolysis zone under pyrolyzing conditions; separating reduced viscosity liquid hydrocarbon lubricant having high VI and low pour point.
    • 公开了通过1-烯烃的较高分子量低聚物的热诱导裂解或热解生产低粘度,高粘度指数液体润滑剂的方法,该产品以高产率生产。 此外,已经发现通过高粘度1-烯烃低聚物的热解生产的降粘性润滑剂保持了起始材料的高粘度指数和低倾点的优异特性。 该方法包括在低聚区域的低聚条件下使C6-C20 1-烯烃原料与多价二氧化硅载体上的还原价态氧化铬催化剂接触,由此产生具有分支比小于0.19并且倾点低于的粘度,高VI液态烃润滑剂, 15℃。 在热解条件下将所述高粘度液体润滑剂通过热解区; 分离具有高VI和低倾点的还原粘度液体烃润滑剂。
