Apparatus is provided for removing a ferrule (71) from a pressurised pipe (70). The apparatus comprises: a housing (3) having a formation (18) at one end. The formation (18) is adapted to engage, in use, with a complementary formation (83) on a pipe sealing device (80). An internal member (2) is mounted on the housing (3) and has a first portion (9) located within the housing (3) and a second portion (5) external of the housing (3). The first portion comprises a ferrule engagement portion (9) and the second portion (5) comprising an operating tool engagement formation (6). The internal member (2) is movable relative to the housing (3) between a disengaged position in which a terminal end (8) of the first portion is located within the housing (3) and an engaged position in which the ferrule engagement portion (9) engages with a ferrule (71) on a pipe (70), in use.

Disclosed is a separator device 10 for removing suspended particles from heating and/or cooling system fluid. The separator device 10 comprises an inlet 16 and outlet 18 for fluid flow, a method of generating a swirl of fluid on entry to the housing 12, a magnetic element and mesh filter 46 positioned between the inlet 16 and outlet 18 and a sediment collection region 76 for the retainment of separated debris. The mesh filter 46 is in the form of a basket, having an open end facing the bottom of the separator device 10, just above the inlet 16, and the sediment collection region 76 is below the inlet.

A separator 10 for removing particles from suspension in a fluid, comprising: an inlet 26a and an outlet 26b for fluid; a mesh 32 between the inlet and the outlet; a turbine 33 comprising one or more vanes 40 to allow a flow of fluid through the separator to rotate the turbine; and one or more brushes 42 or scrapers fixed to the turbine for removing particles from the mesh.

Disclosed is a separator device 10 for removing suspended particles from heating and/or cooling system fluid. The separator device 10 comprises a hydrocyclone separator 38, an inlet 24 to the hydrocyclone separator 38, a sediment collection region 78 disposed below an aperture 46 in the hydrocyclone separator 38, a blocking wall 54 across a central part of the top of the hydrocyclone separator 38 to define an outflow annulus, a mesh basket 44, and an outlet 24 from the separator device 10 for returning fluid back to the central heating and/or cooling system circuit. Suspended particles are primarily removed from the fluid by a vortex that establishes in the hydrocyclone separator 38, and remaining particles are captured and retained in the mesh basket 44 disposed above the hydrocyclone separator 38.

A device for automatically controlling the rate of flow of water out of a radiator in a central heating system is provided. The device includes a temperature sensor disposed within a conduit for detecting temperature of the water flowing out of the radiator and a valve connected to the temperature sensor and disposed within the conduit. The valve is movable to a closed position as the detected water temperature increases to a set point temperature, and to an open position as the detected water temperature decreases below the set point temperature.

A device for protecting, controlling, and monitoring electrical medium range switchgear or other electrical devices comprising use of a Rogowski coil embedded in the bottle of a switchgear and surrounding the Mains flow of current carrying voltage, a capacitive or similar voltage-like divider, also surrounding the Mains and extending around the bottle, and providing analog signals from those devices to an integrated circuit for conversion to digital signals after possible adjustment by look up tables stored on the integrated circuit, and then transmitting as output the digital signals to a data accumulator where the same are optionally time stamped and compared to one another, to a standard or to themselves at a different time.
