摘要： A connector for fluidly connecting a collector pipe and a feeder pipe is disclosed, with a retaining member defining a curved base defining a pair of platforms at opposite ends thereof and facing towards each other upon the connector being mounted on the collector pipe. The base is resiliently deformable such that in a non-deformed state, a radius of curvature of the base is smaller than an outer radius of the collector pipe and a distance between the platforms is smaller than a diameter of the collector pipe. The platforms is displaceable away from each other to vary the distance between them to mount the connector and to exert a clamping force on the collector pipe. The connector has a connecting member engaging the feeder pipe. A piping network is also disclosed.

摘要： A multi-setting connector for connecting at least one secondary branch line to a main line of a sap collection system or network comprises a clip member, a sap conveying member and a pair of straps. The clip member by way of the straps is adapted to be firmly mounted around the main line with the sap conveying member extending through the clip member and into the main conduit and having tubular fittings for connection to the branch lines such that the branch lines are fluidly connected to the main line. The straps are detachable from the clip member with the clip member and the straps being adapted to be selectively connected together such as to adjust an effective length of the straps, typically depending on the outside diameter of the main line. More particularly, the clip member and the straps include co-operating male and female engagement members configured for mounting the straps at various relative positions with respect to the clip member. The clip member is also provided with elongated sockets on its outside surface adapted for detachably receiving a cable or a wire such that the connector may be suspended from such cable when it is desired to maintain the sap collection network, or at least part thereof, at an elevation from the ground.
摘要翻译：用于将至少一个次级分支管线连接到液体收集系统或网络的主线的多设置连接器包括夹子构件，液体输送构件和一对带子。通过带子的夹子构件适于被牢固地安装在主线周围，其中液体输送构件延伸穿过夹子构件并进入主导管并且具有用于连接到分支管线的管状配件，使得分支管线是流体连接到主线。带子可以通过夹子构件与夹子构件分离，并且带子适于选择性地连接在一起，以便通常取决于主线的外径来调整带子的有效长度。更具体地，夹子构件和带子包括配合用于将带子相对于夹子构件安装在各种相对位置的配合的公和母接合构件。夹子构件在其外表面上还设置有细长插座，适于可拆卸地接收电缆或电线，使得当希望将液体收集网络或其至少一部分保持在从地面的高度。

摘要： A high pressure filter support for liquids having low or high viscosity. The support is easily cleanable and quickly dismountable. The support comprises an annular passage defined between an outer larger tubular wall and an inner smaller tubular wall, top and bottom flat plates including quick release fastening means for sealingly joining the top plate to the outer and inner tubular walls to obtain the annular passage sealingly closed. Inlet means into said annular passage are provided. The inner wall inside the annular passage has on its surface a plurality of circumferential grooves. Each of the grooves has at least one orifice through the inner wall. The orifices are of a size commensurate with the viscosity of the material to be displaced through the orifices. An outlet means is sealingly mounted on the surface of the inner wall away from the annular passage to receive the orifices. A system for making maple syrup comprising an evaporator, a filter as defined above is also disclosed. A process for the filtration of maple syrup is also disclosed. It comprises evaporating sap to obtain a syrup, feeding under pressure the syrup, by passing under pressure the syrup between a pair of concentric tubular walls as defined above, the syrup passing from said concentric tubular walls to a filter along said grooves to said orifices, and collecting from said orifices said syrup so filtered.
