Abstract: 1473839 Rotary hearth furnace DAVID ETCHELLS (FURNACES) Ltd 19 Sept 1974 [31 Aug 1973] 41000/73 Heading F4B A rotary heath furnace has a domed roof portion 1 suspended from a bridge structure 2 above a flat surfaced rotatable hearth 3, so that the roof portion lower edges 15 and 15<SP>1</SP> are spaced from the upper surface 13 to form circumferential gaps 16 and 16<SP>1</SP> which allow access to the furnace chamber at the level of the hearth upper surface. The height of the gaps 16 and 16<SP>1</SP> is variable by raising or lowering the bridge structure 2 by means of piston and cylinder assemblies 12. The hearth is rotated by a pinion 6 driven by a motor 7 via an hydraulic transmission 8, and the furnace is heated by flame burners 18.  The roof portion of the furnace has a steel outer shell 19 lined with cast refractory material and may be divided into detachable sectorshaped portions held together by nut and bolt assemblies 21 and 22 (Fig. 3) to facilitate maintenance. Adjacent sector faces of the upper lining are relieved by channels 53 to accommodate thermal expansion and refractory bricks 55 are placed in these channels with an outer layer of insulating felt 56. Articles are loaded on the hearth through the power operated access door 38, and bar-like components can be heated by allowing one end of the component to project into the furnace and the other end to extend from the furnace through the gap 16. The rotary hearth may be provided with a step 14 to reduce the escape of heat at the inner hearth periphery. The invention is applicable to bell-shaped hearth furnaces, Fig. 4 (not shown), and the bridge structure may be mounted on wheels (123) so that the roof portion can be moved to a position clear of the hearth.

A dispensing head for connecting two conduits to the outlet of a container (not shown), such as a beer cask, is provided with a first passage, formed between a body 11 and an inner spring- loaded tubular probe 26, for supplying gas from a connection 20, through a slotted nipple non- return valve 16 to one of two valved passageways (not shown) in said container outlet, and a second passage 27, formed by the probe bore, for discharging beer or other liquid from the other of said passageways, past a ball non- return valve 40 to an outlet connection 36, said probe and body member having a sealing ring 48 and seat 25 respectively, defining valve means which automatically close the first passage when the head is disengaged from the container outlet. During attachment of the head to the container outlet, which may be as described in Specification 958,111, the probe end abuts the inner of the outlet valves and is forced upwards relative to the body to unseat the ring 48 and open the first passage. Cap 30 limits the probe upward movement such that, on continued downwards movement of the head, both inner and outer valves in the container outlet are forced open by the probe. The head is then twisted to lock lugs 13 in corresponding slots of the outlet. On detachment of the head from the container, spring 49 urges the probe downwards to seal ring 48 on to its seat to close the first passage.
