    摘要： A kayak sail system includes a sail including a first extending arm, a second extending arm, and a sail sheet supported between the first extending arm and the second extending arm. A deployment body for the sail includes a base plate supporting a first deployment arm and a second deployment arm. The first deployment arm is coupled to the first extending arm of the sail. The second deployment arm is coupled to the second extending arm of the sail. A support arm is spaced apart from the base plate. A first support post and a second support post extend from the support arm. A first extension spring extends from the first deployment arm and a second extension spring extends from the second deployment arm. The first extension spring is removably coupled to the first support post. The second extension spring is removably coupled to the second support post.

    摘要： Wax-flux compositions for use in low-temperature soldering processes comprise (A) a major amount of a wax and (B) an effective amount to cause fluxing, at or below the soldering temperature of the piece to be soldered, of a wax-soluble product obtained by first reacting an aliphatic hydrocarbon-substituted succinic acid or derivative thereof which is capable of forming carboximide bonds with an alkylene polyamine to form a carboximide and then reacting said carboximide with an alkylaryl sulfonic acid. A process for soldering electrical components to a printed circuit board comprises (A) applying a molten wax-flux composition as described above to the metal pattern side of the board, (B) allowing the wax-flux composition to solidify, (C) trimming the components leads, and (D) soldering the components to the printed circuit board.

    摘要： The present invention has solved the collision problems in a CSMA network protocol and at the same time optimized performance of the network. This is accomplished by giving control of the size of the reserved portion and the size of the reservation portion of the communication frame to stations in the network. Further, the reserved portion is allotted to isochronous data packets each of whose length is variable. Also, only those packets that have a reservation are in the frame, and they are placed in the frame in order in accordance with there position of the permission or reservation list. The network timing is controlled by one of the stations acting as a conductor for the network. This conductor station receives the reservation requests from the other stations and builds a beat packet. The beat packet is transmitted from the conductor station to all stations of the network, and provides the timing or beat of the network that all stations are synchronized with. In addition, the beat packet contains the permission list (reservation list) identifying the stations that will transmit, and when they will transmit during the frame. The network interrupt handler and the conductor at the conductor station build this beat packet.

    摘要翻译： 本发明解决了CSMA网络协议中的冲突问题，同时优化了网络的性能。 这通过将通信帧的保留部分的大小和通信帧的预留部分的大小控制到网络中的站点来实现。 此外，保留部分被分配给每个长度可变的同步数据分组。 此外，只有具有预约的那些分组在帧中，并且它们根据许可或预约列表的位置按顺序被放置在帧中。 网络定时由作为网络的导体的一个站控制。 该导体站接收来自其他站的预留请求并构建节拍包。 节拍包从导体站发送到网络的所有站点，并提供所有站点同步的网络的定时或节拍。 此外，节拍包包含识别将要发送的电台的许可列表（预约列表），以及何时将在帧期间发送。 网络中断处理程序和导体站处的导体构建这个节拍包。
