摘要:
An assembly (10) secures to a structure (80) a panel or two juxtaposed panels (11, 12) each having a joining flange (15) in association with an edge thereof defining a longitudinal axis of the panel. The joining flanges are fastened by at least one securing element (16) that may include or have associated therewith a respective retaining member (30). For each securing element (16), a respective support element (20) is fixedly mounted to the structure and configured for slidably supporting the panels in a direction parallel to the longitudinal axis. Each support element (20) supports opposing side walls (22, 23) forming a channel (24) dimensioned for free sliding therein of the respective securing element (16) or associated retaining member, and each panel is supported by the at least one securing element without applying lateral pressure to the side walls (22, 23) of the respective support element (20).

摘要:
A sprinkler comprising a housing fitted with an inlet port connectable to a water supply line and extending into an inlet chamber, a hollow stem member with an inlet end thereof being in flow communication with said inlet chamber and an outlet end thereof being in flow communication with an irrigation head, a diaphragm seal sealingly fixed at peripheral boundaries thereof to the housing and sealingly articulated to the stem member and supporting it at an essentially upright position. The diaphragm is deformable between a first position in which the irrigation head is retracted within the housing and a second position in which the irrigation head projects from the housing. The sprinkler comprising at least one guard portion adapted to prevent insects and undesirable material from entering the sprinkler housing during said second position.

The present invention relates to a drip chamber for an intravenous infusion set. The invention also relates to a method of making drip chambers, and further, to an intravenous infusion set including a drip chamber. The invention is provided with a drip chamber comprising a housing defining a chamber to be located in a vertical position and including an inlet at the top and an outlet at the bottom; a first hydrophilic filter covering the outlet effective, when wet, to permit the flow therethrough of a liquid and to block the flow therethrough of air; and a second hydrophilic filter covering the inlet also effective, when wet, to permit the flow therethrough of a liquid and to block the flow therethrough of air.
