Abstract: Provided is a monitoring device (1) for gaseous fuel. The device comprises a body (2) formed with a reservoir (45) covered with an observation window (68), an inflow passage (86) extending from an inlet port (3) into the reservoir, and an outflow passage (58) extending from an outflow port (4) to the reservoir. The inlet port is for connection to a gaseous fuel source and the out let port is for connection to gas conveying means (214) for supplying gaseous fuel from the network or container (s) to one or more gas appliances. The reservoir is partially filled with a mixture of a liquid which remains in liquid state between at least from ?5° to 50° Celsius and a surfactant capable of breaking down oily substance. The liquid mixture is filled to a level above the inner end of the inflow passage. One or more baffle members (61) are provided in the reservoir at a position above the liquid mixture and the baffle member extends across the outflow passage.

Abstract: A beverage can cap member is configured so that its exterior surface extending radially inwardly from the rim or rim forming portion is substantially flat or continuous, or has a slight curve from a position adjacent from the rim or rim forming portion. The cap member may have a countersink which is filled with a filler material including a curable adhesive, an insert of a natural or synthetic material or the like. The filler material increases the structural strength of the cap member to an extent that it can be made of a relatively thinner material and still complies with the minimum peaking pressure of the industrial standard.

Abstract: A beverage can cap member (16, 100) is configured so that its exterior surface (28) extending radially inwardly from the rim (18) or rim forming portion (140) is substantially flat or continuous, or has a slight curve from a position adjacent from the rim (18) or rim forming portion (140). The cap member (16, 100) may have a countersink (160) which is filled with a filler material including a curable adhesive, an insert (180) of a natural or synthetic material or the like. The filler material increases the structural strength of the cap member (16, 100) to an extent that it can be made of a relatively thinner material and still complies with the minimum peaking pressure of the industrial standard.
