Title: Storage type electric hot water heater - has flow restriction in inlet to prevent outlet temp. dropping excessively
IPC: F24H9/20
Filed: 1976-06-28
Abstract: The heater has a reservoir (1) within an outer insulated casing. Water enters the reservoir from a cold water inlet (2) through a ball valve (13). The reservoir has an electric immersion heater (6) which is controlled by a thermostat (10). The hot water outlet (4) is controlled by a hand operated valve (5) and as hot flows out cold water flows in to maintain the level in the reservoir. The cold water inlet has a calibrated orifice (18) which restricts the flow in to a rate such that the immersion heater can raise it to the outlet temp. as it flows through the heater. This ensures that the temperature of the water drawn off does not drop if water is run for a long time.

Title: Anti:icing equipment for aircraft control surfaces - has aerofoil in front of surface to accelerate airflow without affecting aerodynamics
IPC: B64D15/00
Filed: 1976-07-06
Abstract: The anti-icing equipment for aircraft aerodynamic sufaces, esp. horizontal control surfaces, is an aerofoil (4) running the full length of the surface (2), mounted parallel to it on struts (12) projecting forwards from it's leading edge (5). The aerofiol's chord (8) is 3-8% of the main surface chord and inclined to the plane (10) of the latter at between 30 and 60 deg. (9). More of the aerofoil is below the main surface centre-line than above it. The gap (11) between aerofoil nose and main surfacae leading edge (5) is 1-3% of the latter's chord. The aerofoil's shape causes airflow acceleration over the main surface leading edge, discouraging icing, without affecting aerodynamic characteristics.
