Abstract: 329,145. Appareils et Evaporateurs Kestner- April 3, 1929, [Convention date]. Addition to 279,037. Calcium nitrate.-In a modification of the process of the parent Specification, calcium nitrate is prepared by the action of nitric acid on calcium carbonate in the presence of a solution of calcium nitrate. Bv this means, the heat evolved is dissipated in a larger mass, thereby avoiding a large rise in temperature and a corresponding loss of nitrogen oxides. The solution may be mixed, prior to the reaction, either with the nitric acid or with the carbonate of lime. The apparatus used in the parent Specification may be modified so that a mixture of nitric acid and cooled calcium nitrate solution passes over pieces of carbonate of lime; or for treatment of sediment of carbonate of lime, such as proceeding from caustification or from the production of ammonium sulphate by the gypsum process, the apparatus illustrated in Fig. 2 may be employed. The sediment is fed into tank 15, and there mixed with calcium nitrate solution from tank 11. The suspension is pumped through a cooler 14, nitric acid added thereto at 16, and passed into a cyclone separator 6, when the froth is broken up. Carbon dioxide is drawn off by the pump 9, and calcium nitrate solution collects in 11. Specification 289,370 is referred - to.

[Class 110 (iii)] [Also in Group XXIX] A hydraulic speed governor for a gas turbine, employs the engine fuel as the controlling fluid and comprises a centrifugal impeller driven by the engine, a pressure-responsive device exposed to the pressure difference across the impeller, a manually-adjustable datum-changing device for varying the bias on the diaphragm, and a valve controlled by the diaphragm for regulating the flow of fuel supplied to the engine. In an embodiment, an engine-driven centrifugal impeller 23 is connected across a diaphragm 22, an aperture 126 in the diaphragm permitting the flow of fluid from the tip to the eye of the impeller. The diaphragm is biassed by a spring 26, the rate of which can be varied by a manually-actuated lever 29, and the diaphragm controls a valve 139 constituting a leak-off valve in the fuel line 21 leading to the engine whose speed is being controlled. Fuel is pumped by an engine-driven gear pump 11 past the tip of the impeller to one side of the diaphragm and to the line 21, and the fuel that leaks off past the valve 139 flows back to the inlet of the pump 11. In a modification, the valve 139 is replaced by a piston valve controlling the flow of fuel under pressure from pump 11 to a double-acting servo-piston which controls the leak-off valve from the line 21. The piston valve is counterbalanced by applying pressure fluid to that end of it opposite to the one connected to the diaphragm. In a modification of this last arrangement, the leak-off from the line 21 is replaced by a throttle valve in that line, and a separate leak-off with a diaphragm-actuated relief valve is provided between the outlet and inlet of the pump 11. According to the Provisional Specification, oil may be the motive fluid of the system.

Abstract: 611,941. Boundary layer control. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., LLOYD, J., and MURRAY, C. V. May 13, 1946, No. 14459. [Class 4] In order to reduce the tendency for tip stalling, particularly in tailless aircraft with swept-back wings and powered by an internal combustion turbine unit, the turbine intake is arranged along a streamlined passage provided with shutter means normally forming part of the passage wall but movable to a position partially blocking the passage, so as to cause a depression or reduction of pressure therein, the region of the depression being in communication with an opening in the upper surface of the wing, near the tip thereof, whereby air will be drawn in from that portion of the wing surface, partly by the depression and partly by the suction of the power unit, when the shutter is so moved from its normal position. In the form illustrated, an aircraft is powered by two turbine units 12, one in each wing, the intake 16 of each being provided with shutter flaps 18, 19 connected by a link 20, and operable by the pilot's main control member 36 and the throttle lever 37 through a hydraulic servomotor 21. The shutters move to the positions 18a, 19a, Fig. 5, when either of the controls 36, 37 is moved to the fully back position, and to the positions 18b, 19b when both controls are moved back simultaneously. The regions 23, 24 of the intake near the shutters are placed in communication with openings in the upper tip surfaces of the respective wings by ducts 25, 28, in order that should one of the turbine units fail the other will serve to remove the boundary layer from the upper surfaces of both wing tips. The supply of liquid to the jack 21 is controlled by piston valves 39 operated by the control levers 36, 37. In addition to reducing the tendency to tip stalling, the arrangement ensures that the turbines receive sufficient input of air.
