    摘要: In a gate, a stile (20) and rail (21) abut side face to end face and are held together by a bolt passing at right angles through the end face to pull against a plate (25) located in a slot (26). Straps (34,41), see FIGS. 11 and 13, are used to reinforce the hanging and shutting stiles (20,20A) and to carry hanging and latching parts. A latching mechanism, see FIGS. 13 to 16, includes a latching bar (43) that is pivotally connected to the shutting stile (20) towards its middle by a flange (44). A leaf spring (45) urges the bar (43) into a latching position at which, when the gate is shut, the bar (43) is caught behind upper and lower retainers (46) mounted on a shutting gatepost (48). By pulling on a handle (50), the bar (43) can be rocked free of the retainers (46) to permit the gate to be opened. Connector plates ( 31) having sharp tongs are used, see FIGS. 9 and 10, with bolts to connect reinforcing struts (30) to the upper and lower rails (21,21A). Upper and lower hinge brackets for mounting on a hanging gatepost are also provided, see FIGS. 17 to 23.

    摘要: Fasteners such as bolts or nuts are locked by a ring and associated keys. The ring typically has a series of holes with the fasteners passing through these holes in the ring. The ring has an outer surface with studs extending upward therefrom. Typically one key for each fastener is placed adjacent to the ring after the fasteners are tightened against the ring in each hole of the ring. The key has a head opening which fits over a head of the fastener and keeps the fastener from rotating. The key also has a bore which fits upon the stud, with the stud preventing key rotation, and the key in turn preventing fastener rotation. A retainer such as a lock nut on a threaded stud or a snap ring in a grooved stud hold the key to the ring and keep the ring in position locking the fasteners.

    摘要: A ring network system (1) has at least one node M which acts as a master or sender node to transmit an outgoing signal (O.S.1) having a relative address determined according to the relative location of the addressee node in the system. As the outgoing signal passes through each node in turn, it is changed and a node recognizes that it is the addressee node if the relative address has a predetermined common addressee value. The addressee node generates a return signal (R.S.1) with a node identifier which is transmitted in the opposite direction to the outgoing signal and the sender node ensures that this is received for a valid poll. The master node (M) may automatically configure itself by retrieving the identifier of all nodes in response to outgoing signals. This allows nodes to be easily added or deleted. Each node on the return path adds data which it has captured together with its identifier so that data may be captured from all nodes between the sender node and the addressee nodes. A node (M) may transmit outgoing signals alternately in opposite directions in a manner whereby the addressee nodes are selected so that each communication link (3-8) is omitted in sequence and fault diagnosis takes place.

    摘要翻译: 环网系统(1)具有至少一个节点M,其作为主节点或发送节点发送具有根据收件人节点在系统中的相对位置确定的相对地址的输出信号(O.S.1)。 随着输出信号依次通过每个节点,如果相对地址具有预定的公共收件人值,则其被改变,并且节点识别它是收件人节点。 收件人节点生成具有与输出信号相反方向发送的节点标识符的返回信号(R.S.1),并且发送方节点确保为有效的轮询接收到该信号。 主节点(M)可以通过响应于输出信号检索所有节点的标识符来自动配置自身。 这样可以轻松地添加或删除节点。 返回路径上的每个节点将其捕获的数据与其标识符一起添加,以便可以从发送方节点和收件人节点之间的所有节点捕获数据。 节点(M)可以以相反方向交替地发送输出信号,从而按照收件人节点进行选择,使得顺序地省略每个通信链路(3-8),并进行故障诊断。
