摘要： A carriage having rotary cutter wheels is mounting for reciprocation on a frame adapted to be rigidly secured to a pipe casing which is desired to be split along a line parallel to its axis. A hydraulic motor is mounted to the frame at one end of the carriage. A rotary crank driven by the motor is coupled to an arm which is also coupled to drive the carriage in a reciprocating motion. An adjustable hydraulic valve controls the speed of the motor, and thus the speed of the cutter. An adjustable stabilizer is mounted to the frame to stabilize the cutter by bracing against the carrier pipe within the casing.

摘要： A game board apparatus for use by two teams of players is provided. The game board apparatus includes a grid of equal sized squares. Two of the squares represent starting points for each of the teams, respectively. Further, two adjacent clusters of squares form reserved areas for each of the two teams, respectively, which permits only the team that owns the reserved area to start a word within the reserved area. A bonus bridge dividing line is positioned between the two reserved areas. Bridging the two arrays emanating from the respective starting points and forming a word which crosses the bonus bridge dividing line yields additional bonus points.
摘要翻译：提供了两组玩家使用的游戏机装置。游戏板装置包括具有相等尺寸的正方形的网格。两个方块分别代表每个队的起点。此外，两个相邻的正方形组分别形成了两个队中的每一个的保留区域，这仅允许拥有保留区域的团队在保留区域内开始一个单词。两个保留区域之间定位一个奖励桥接分界线。连接从各个起始点发出的两个阵列，并形成一个穿越红利桥接分界线的单词，产生额外的奖励积分。

摘要： An electrofusion fitting for sealing a distribution line, or main, includes upper and lower arcuate sleeve members securely coupled together about the line by means of nut and bolt combinations. Extending radially from the upper sleeve member is a cylindrical flange with a threaded end portion through which a line tapping tool may be inserted for either inserting a seal in the line or for coupling a branch line to the distribution line. A pair of electrodes extending from the upper sleeve member form an electrofusion circuit with a heating conductor disposed intermediate the line and upper sleeve member for forming a fusion bond therebetween. A sealing gasket is disposed about the flange opening in the upper sleeve member to provide an immediate, temporary seal between the upper sleeve member and the line to permit rapid sealing of the line followed by permanent electrofusion sealing of the fitting on the line permitting the immediate tending to any necessary repair work to the line. The fitting is preferably comprised of polyethylene for secure bonding to a distribution line of like composition.
摘要翻译：用于密封分配线或主体的电熔接头包括通过螺母和螺栓组合将线连接在一起的上部和下部弓形套筒构件。从上套筒构件径向延伸的是具有螺纹端部的圆柱形凸缘，通过该圆柱形凸缘可以插入线攻丝工具以将密封件插入管线中或用于将分支管线连接到分配管线。从上套筒构件延伸的一对电极形成电熔电路，其中设置在线之间的加热导体和上套筒构件，用于在它们之间形成熔接。密封垫圈围绕上套筒构件中的凸缘开口设置以在上套筒构件和管线之间提供即时的临时密封，以允许快速密封管线，然后在管线上进行永久性电熔融密封，允许立即倾向于进行任何必要的维修工作。该配件优选地由聚乙烯组成，用于牢固地粘合到类似组合物的分配线。

摘要： A digital switching device of the stored program type operating under the control of a central control unit has a first stage which multiplexes digital signals from a plurality of line units and separates data signals from signalling information. The data signals are fed to an input time switching stage. The input time switching stage operates under the control of the central control unit to transmit signals from an input port in a particular time slot on a highway to an output time switching stage. The output time switching stage transmits the data signals to the first stage which combines them with signalling information and after demultiplexing transmits them to appropriate ports.
摘要翻译：在中央控制单元的控制下操作的存储节目类型的数字切换装置具有多路复用来自多个线路单元的数字信号并将数据信号与信令信息分离的第一级。数据信号被馈送到输入时间切换级。输入时间切换级在中央控制单元的控制下操作，以将高速公路上特定时隙中的输入端口的信号传输到输出时间切换级。输出时间切换级将数据信号发送到与信令信息组合的第一级，并且在解复用后将它们发送到适当的端口。
