Abstract:
An improved jack for using leverage and the momentum of the vehicle or trailer to be lifted to raise the vehicle or trailer. The jack has a cradle to engage the axle of the vehicle or trailer to be lifted. The cradle is adapted to prevent the vehicle or trailer from slipping off the jack. The cradle is connected to a telescoping member which is inserted into a post that is connected to a based plate. The base plate is configured to allow the post and telescoping member to pivot to a vertical position as the vehicle or trailer is driver over the jack.

Abstract:
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 the 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.
Abstract:
An apparatus for lubricating an operating component of a system in which the operating component is exposed to a range of conditions, such as a range of temperatures which require adjustment of at least one physical property of the lubricant, is described. In one embodiment, the apparatus is useful for lubricating more than one operating component, each operating under a different operating condition. The apparatus utilizes a first lubricant and a second lubricant which are at least partially miscible, under a condition of at least partial miscibility, usually an elevated temperature. Under the condition of at least partial miscibility, the lubricants combine to provide a third lubricant. The third lubricant is dispensed to the operating component in response to a change in at least one operating condition which requires the properties of the third lubricant for efficient lubrication.
