Abstract
1,175,532. Electricafly heated pressure head for aircraft. AVIMO Ltd. 17 May, 1967 [6 July, 1966] No. 30357/66. Heading H5H. A pressure head comprises an outer housing 2 and an inner core 1 of a metal of high thermal conductivity e.g. copper, and an electric heating element 10, 11 embedded in a sodium silicate composition between the core 1 and housing 2. The sodium silicate composition is moulded on the cover and many include some silicone rubber and/or a suitable filler such as one or more of the following: marble flour; sand; silica flour; mica flour; slate powder; zircon powder; or chopped glass strands. The heating element preferably comprises ceramic coated wire. Two heating elements 10 and 11 are provided for alternative use at different voltages. The pressure head is mounted a mast 8 of aerofoil cross-section heated by one or two heaters 9.
