Title: Hothouse with thermally insulated roof - has layer with sandwich construc-tion utilising artificial wool between plastics sheets
IPC: A01G9/14
Filed: 1973-06-15
Abstract: The hothouse is typically for horticultural applications for expedition of plant growth. The construction comprises a flat roofed building with V-section portal frames. Beneath the main roof is an insulating layer of double cantilever construction, consisting of a sandwich between two light, waterproof plastics sheets, with a filling of glass or mineral fibres, supported by chipboard. This construction maintains a heat transfer coefft. (k) of over 0.6 Kcal/M2/hr/deg. so that an inner building temp. of +15 deg. may be retained when only -8 deg. outside. The long sidewalls of the main building are transparent to admit sunlight.

Title: Television suppression circuit suppresses colour-carrier components - in luminance channel using differential amplifier receiving luminance and vestigial colour-carrier signals
IPC: H04N9/78
Filed: 1975-03-06
Abstract: The selective suppression circuit, for coders in television receivers, suppresses colour-carrier components that appear in the luminance channel. The suppression circuit acts as an amplitude-dependent filter and has a differential amplifier. The luminance signal and the colour-carrier vestigial signal are applied to the two inputs of the differential amplifier. The vestigial signal is obtained by filtering. The luminance signal free of colour components appears at the amplifier output to the limited output of the filter to the where it is added to the limited output of the filter to the limited vestigial signal.
