摘要： Before effecting a cut-out operation to remove a section 24 of a pipeline such as a gas main, the pipe 10 is pre-loaded by clamping clamp assemblies 12, 14 around the pipe 10 and locating yokes 16, 18 against the assemblies. Struts 20, 22 engage the yokes and include hydraulic cylinders 32 which can be pressurized by a pump 30. Nuts (38) can be tightened onto the cylinders 32 to maintain the pre-load when the hydraulic pressure is removed. The force applied equals the otherwise unbalanced gas load "A" or "B" provided by the gas pressure in the pipe 10 acting on the stop plugs. Each clamp assembly comprises thrust members tightened against the pipe 10 by chains. The forces applied pre-loads the yokes equal to the forces provided by the gas pressure in the pipe 10 acting on the stop plugs. The thrust members are located on fabric straps which are adjusted to make the members equispaced and then tensioned to lock them in place before the chains are tensioned.

摘要： Cutting apparatus is provided for cutting a hole or `window` in the wall of a pipe for example prior to joining a branch pipe to a host pipe. The apparatus comprises a chassis frame 14 carrying a cutter unit 42 supporting a cutter tool 62. The chassis is attached to and movable around the pipe 12 by means of `roller` chains 24. The cutter unit is movable with respect to the chassis frame by means of the associated slider block 38 which is slidable along longitudinally extending chassis frame which is slidable along longitudinally extending chassis frame members 16. Thus, the cutter tool 62 can be moved relative to the workpiece in one sense by movement of the chassis frame 14 and in another sense by movement of the cutter tool relative to the chassis frame. A combination of such movements enable the hole or `window` to be cut.
摘要翻译：切割装置用于在例如在将支管连接到主管之前在管壁中切割孔或“窗”。该装置包括承载支撑切割器工具62的切割器单元42的底盘框架14.底盘通过“滚子”链条24附接到管12上并可通过其移动。切割器单元可相对于底盘框架移动相关联的滑动块38的装置，其可沿着纵向延伸的底架框架滑动，所述底座框架可沿着纵向延伸的底架框架构件16滑动。因此，刀具工具62可以通过底架框架14的运动而在一个意义上相对于工件移动，在另一个意义上，通过刀具相对于底盘框架的移动。这种移动的组合使得能够切割孔或“窗口”。

摘要： A method of sealing a joint in a gas main comprising boring a hole in the wall of the main at a point spaced from the joint, inserting into the main through the hole so formed a sealant spraying means, moving the spraying means to the site of the joint, pumping a settable anaerobic type sealant to the spraying means, causing the spraying means to spray the sealant onto the inner wall of the main to form a layer covering the joint, removing the spraying means through the hole and allowing the sealant to set.

摘要： A trencher comprises a ground running, powered vehicle which travels in a forward direction carrying a trenching wheel driven by power to rotate in a vertical plane containing the forward direction so that cutting tips on the wheel's periphery excavate spoil from the ground leaving a trench therebehind. A plough just behind the front end of the trenching wheel pushes the spoil aside from the trench. The plough comprises two blades in V-shaped disposition, each blade being at a respective opposite side of the trenching wheel with leading ends of the plough blades being nearer sides of the wheel then their trailing ends. The plough blades, which are vibrated by vibrators driven by hydraulic motors, are mounted by elastically deformable anti-vibration mountings on respective supporting plates alongside the plough blades. The plough blades and these plates are raisable and lowerable hydraulically, and can be held braced in any desired V-shape by hydraulic struts.

摘要： The invention relates to a method of treating an aqueous liquor, such as effluent liquor formed during coal gasification. The method comprises subjecting the liquor to dephenolation and ammonia stripping treatment to remove phenolic compounds and "free" ammonia from the liquor and then subjecting the resulting liquor, which still contains ammonium compounds and thus "fixed" ammonia, to reverse osmosis treatment to produce a permeate which is substantially free from impurities, including "fixed" ammonia.

摘要： An acoustic matching member for a sonic transducer is disclosed which comprises a solid material, for example, a glass, in which a plurality of voids have been formed. A method is also included of forming an acoustic matching member for a transducer which includes the steps of forming the member from a material in which a plurality of voids have been introduced whereby the velocity of sound in the material with voids is substantially less than that of the material without voids in the direction of sound propagation of the member.

摘要： A liner 30 of polyethylene housing an SDR of 33 or less is pulled through a die 36 and through the pipe 10 and allowed to revert to the internal diameter of the pipe. The force of pulling is half the yield strength of the liner or less. The die has an entry; a throat and an exit, the entry decreasing in diameter towards the throat and the exit increasing in diameter away from the throat. The liner has a maximum diameter before the die, a minimum diameter in the die and intermediate diameter after the die. The liner bending inwards before first contacting the die at the entry, then continuously bending through its minimum diameter as it passes the throat and then undergoing die swell resulting in said intermediate diameter. The throat is defined by the merger in a continuous curve of a radius joining the entry and a radius joining the exit.

摘要： The invention relates to a method of operating an adsorption system using only two adsorption beds, for control of output quality of a gas containing a hydrocarbon. In the method before complete changeover of one bed A from adsorption to regeneration and of the other bed B from adsorption to regeneration, the adsorption feed gas flow is split into two streams of equal flow rate in the embodiment described, flowing in parallel through the beds and recombining the gas from the adsorbing bed A and the regenerating bed.
