Abstract: Provided is a body of a hand-held metal detector which includes an elongated body with a first and second end; and a first connecting structure moulded directly onto the elongated body at the first end through an injection moulding process. The connecting structure includes an engaging portion configured to engage at least one attachment of the hand-held metal detector, such that the at least one attachment is supported by the elongated body through the connecting structure moulded directly onto the elongated body.

Abstract: A soft closing liquid valve of the pilot control type including an inlet chamber, an outlet chamber, a third pilot chamber, a first conduit for liquid communication between the inlet chamber and the third chamber and a second conduit for fluid communication between the third chamber and the outlet chamber whereby the liquid flow rate through the first conduit is reduced by the conduit including a tortuous path means so that the flow rate into the third chamber is substantially reduced and when the second conduit is closed causes the third chamber to fill at a slower rate than in conventional pilot controlled valves, the resultant slow rate of change of pressure causing a slow closure of the flow path between the inlet and outlet chambers by a diaphragm thus minimizing water hammer.
