Abstract: 1377148 Electrostatic spraying apparatus AIR INDUSTRIE 15 June 1942 [2 Aug 1971] 28149/72 Heading B2F  A method of electrostatic spraying of an object with a liquid coating product from a spray nozzle outlet includes, to reduce fouling of the nozzle with rebounding particles of the coating product, charging an auxiliary liquid to a high voltage and ejecting the liquid simultaneously with the liquid coating product towards the object from regions situated about the outlet of the spray nozzle. The auxiliary liquid is compatible with the liquid coating product, e.g. water in the case of enamel and solvent in the case of paint, and may be sprayed in a liquid-only form, or as a liquidgas mixture. In the apparatus shown in Fig. 1, the auxiliary liquid is supplied through an inlet 13 having a venturi, Fig. 3 (not shown). An air-liquid mixture leaving the venturi passes into a mixing chamber 10, and enters into a second mixing chamber 11 through tangential conduits in a vortical motion. The mixture is then ejected through hollow needles 9 having bevelled ends and spaced around the periphery of the nozzle, and the needles are charged with the same polarity as the nozzle. Alternatively, the auxiliary liquid may be charged and sprayed from a device separate from the nozzle (not shown). Parts 1 and 2 of the nozzle are metallic and form the charging electrode for the liquid coating product.

Filed: 1960-08-22
Abstract: 898,203. Boundary layer control on helicopter blades. HILLER AIRCRAFT CORPORATION. Aug. 22, 1960 [Aug. 24, 1959], No. 28934/60. Class 4. A helicopter rotor blade, adjustably mounted for pitch change, has boundary layer control means including operating means therefor comprising a first member fixed on the blade, and a second member movable on the blade under the control of restraining means operative in response to conditions of flight independent of the angle of attack of the blade, relative movement between the first and second members operating the boundary layer control means. Fig. 2 shows a rotor blade tip, a hollow spar 3 receiving compressed air through the hollow rotor shaft from a compressor or gas turbine engine, and communicating through valves (not shown) with ducts 9 leading to a trailing edge slot 10. The valves are controlled by a rod 12 secured to an arm 13 on which are a small aerofoil 14 and a mass balance 15. The aerofoil 14 keeps the arm 13 aligned with the relative wind direction W, and when the angle of attack of the retreating blade increases, rotation of the blade relatively to rod 12 opens the valve so that an air jet 10a is discharged from slot 10, to increase the lift of the blade and delay the onset of stall by energising the boundary layer. In an alternative, the rod 13 has two masses, one at each end so that the rod remains parallel to the tip path plane by gyroscopic effect as the rotor rotates. In either embodiment, power consumption is minimized by discharging compressed air only when needed. The compressor may be driven from the gearbox of an engine driving the rotor shaft.
