Abstract: A method for detonation of a plug device in a fluid environment is described, which is in contact with a body, such as an ignition pellet, and it is characterized in that a number of pressure increases are exerted against the plug device, whereby each pressure increase causes a movement of a piston (10) which is radially arranged in a casing (12), which causes the casing (12) to move a fixed distance inward in the plug device with each pressure increase, up until the displacement of the casing (12) causes the piston to be displaced into a cavity (38), and the fluid environment enters the plug device via an inlet. Also described is a plug device which is in contact with a body, such as an ignition pellet, where the plug device is arranged to detonate after a number of pressure increases that are exerted against the plug device.

Abstract: A strip of membrane material is laminated to a wider strip of netting and then the longitudinal edges of the strip of netting are seamed together into a sleeve for receiving aggregate to form an elongated tubular drainage element. The laminated peripheral portion of the resultant sleeve is used as the top of the drainage element to preclude fine material from entering the drainage element. Where a membrane is used to form the sleeve, holes or slits are placed in the peripheral portion of the sleeve that is to form the bottom of the drainage element. The seaming of the overlapped longitudinal edges of the membrane is effected using glue and a nozzle that blows air under pressure onto the seam to force the edges and glue to bond together.

Abstract: The test procedure for determining groove conformance employs a replicating compound to obtain a self-supporting mass with a negative image of the grooves of a club face. A thin test specimen strip is sliced from the mass and then scanned to form an electronic trace of the profile of the ribs. A negative image of the profile of the ribs is then obtained as a replica of the profile of the grooves and the grooves measured to determine conformance to USGA Rules. A protective covering may be placed on the self-supporting mass to insure the integrity of the ribs during slicing.
