Patent GB-2097490-A (GB)
Title: Ring seals
IPC: F16J15/44
Filed: 1981-04-24
Abstract: A ring seal is provided with a pressure balancing arrangement which offsets the loads normally applied to the ring and which tend to cause it to jam. The seal comprises a housing 15 within which the ring (21) operates, the ring dividing the interior volume of the housing into at least two chambers (24, 25, 26). The exterior pressures are fed to the chambers so that the higher pressure enters the inner chambers (25, 26) to tend to lift the ring off its co-operating surface, while the other chamber (24) is supplied with the lower pressure and provides a relatively low load which tends to force the ring into contact with the surface. The inner chambers (25, 26) differ in height to provide a desired side load. <IMAGE>

Patent GB-2146762-A (GB)
Title: Fire bottom grate
Inventor: KELLY KENNETH
IPC: F23H13/00
Filed: 1984-07-05
Abstract: The invention is a new design of bottom grate for solid fuel fires. Instead of the traditional flat surface the invention has a convex surface. The invention also includes a dome-shaped metal casting with slots or airways as in a bottom grate. It can be placed on a flat bottom grate to give a convex centre. The object of the invention is to reduce the amount of fuel in the interior or core of the fire without reducing the surface area of the fire. By this means, the heat radiated into the room is maintained or increased (due to increased air supply) but the heat generated in the interior of the fire, which is lost up the chimney by convection, is reduced by virtue of the fact that the amount of fuel in that part of the fire has been reduced. <IMAGE>
