Plug for high-pressure processing machines with a bag, comprising a duct for the passage of a pressure-transmitting fluid to the bag, another duct for filling and emptying of a product to be pressurized and a valve. The plug is further provided with a rod for opening and closing the valve. Said rod is located in the duct for the product and has its own inner duct joined to a cleaning agent chamber for the passage of the cleaning agent through the product duct. The invention also relates to a machine incorporating said plug and a method for the processing of pumpable substances. Hygienic design and very high pressure sealing requirements are met by the invention.

An assembly 10 includes a coupling member 12 having a first annular, radial connection flange 22 and a blanking cap 14 comprising a disc-like member 30 which defines a second, corresponding annular, radial connection flange 34. The connecting flanges are clamped together by a clamp (16) with a seal member 18 in-between. The blanking cap comprises a pair of safety lugs 62 attached to the disc-like member which each extend about an outer circumferential periphery of the first connection flange 22. Each safety lug has an abutment 68 for engagement with the first connection flange to limit axial movement of the disc-like member away from the coupling member. The lugs 62 prevent the blanking cap from flying off in the event the clamp is released whilst the interior of the coupling member is pressurised. The lugs 62 may each have a stop member 66 which defines the abutment and which may take the form of an elongate curved member extending circumferentially about an axis of the connection flanges. The clamp may be tri-clamp.

A closure assembly for a fluid port having a fluid flow channel defined along an axis, the channel ending in a port opening. The assembly includes: a closure cap extending in a first plane arranged to seat across, and close the port opening, in use, in a closed state, a guide arm extending from the cap in a second plane substantially perpendicular to the first plane; a lifting guide to accommodate and retain the guide arm for movement of the guide arm in the second plane as the cap moves axially away from the opening; and a pivot mechanism between the guide arm and the lifting guide about which the cap is able to pivot relative to the lifting guide to an open position.

A propane tank seat accessory device provides an upper seating surface to support a user seated thereon on a portable propane tank with a cylindrical body and a protective cage surrounding a valve at the top end thereof. The device has a seat with a lower supporting surface for being supported on an upper edge of the protective cage and which defines the upper seating surface thereon. A sleeve extends downwardly from the lower supporting surface having an exterior diameter receivable within the protective cage of the propane tank in which a bottom end of the sleeve can be engaged upon the top end of the tank body. The sleeve has a valve opening therein for communication of the valve structure therethrough.
