Title: Boundary layer control for aircraft
IPC: B64C21/06
Filed: 1946-02-05
Abstract: 607,457. Boundary layer control. GOODYEAR AIRCRAFT CORPORATION. Feb. 5, 1946, No. 3590. Convention date, Feb. 10, 1945. [Class 4] [Also in Group XXVI] An aircraft is provided with a jet engine with a nozzle terminating at the rear of the fuselage, a casing spaced from and surrounding the jet tube for substantially its full length forming a suction pump operated by the exhaust gases being connected to slots in the wings for promoting boundary layer suction. The aircraft illustrated is provided with an internal-combustion engine 12 driving a propeller in addition to the gas turbine 13, the exhaust of which discharges through the jet tube 14. The turbine and tube are enclosed in a casing 25 provided with a forward extension 26 into which is led the exhaust pipe 16 of the engine 12. Boundary layer air is drawn through slots 20 in the surfaces of the wings, ailerons and flaps into conduits 21 connected with the casing 25, the necessary suction being provided by the exhaust from the turbine and/or the engine 12, under the control of valves 28, 29. The turbine and jet tube are cooled by the air flowing between the casings 14 and 25. The starter motor 27 may be used in the event of failure of the turbine to promote sufficient suction to remove the boundary layer. The ailerons or flaps 8, Fig. 4, are hinged to the lower surfaces of the wings 7, the gaps in the upper surfaces being bridged by strips 11 which preserve the aerofoil profile. Ducts 22 communicate with the slots 20 in the ailerons or flaps, and by flexible connections 23 with the main conduits 21. Valves 17 may be provided to control the suction at the lower wing slots.

Title: Improvements relating to high frequency measuring apparatus
IPC: G01R21/00
Filed: 1947-02-07
Abstract: 635,235. Power meters. MILLING, M. C. CROWLEY-, and METROPOLITAN VICKERS ELECTRICAL CO., Ltd. Feb. 7, 1947, No. 3736. [Class 37] A device for measuring H.F. power consists of a low-frequency A.C. bridge circuit ABCD, wherein three arms are resistances and the fourth AC is a thermistor type resistance T. The output voltage is amplified and applied to a mixer M, the output of which is rectified and heats the thermistor. The mixer is so biassed by the source supplying the bridge that its output with zero input brings the thermistor to the condition in which the bridge is balanced. When H.F. power also is fed to the thermistor via terminals R.F., the temperature of the thermistor rises and the resulting unbalance voltage reduces the output of the mixer so that the temperature of the thermistor only changes slightly and the bridge is only slightly unbalanced. The change in current from the rectifier as shown on the meter G indicates the change in the heating of the thermistor due to the applied H.F., and by suitable calibration, the meter G can provide a direct indication of the applied H.F. power.

Patent GB-607582-A (GB)
Title: Improvements in the production of crease-resisting mercerised linen textile materials
IPC: D06M15/423
Filed: 1946-02-08
Abstract: A mercerized linen material is impregnated with a urea-formaldehyde resin and the resin is insolubilized within the fibres so as to improve the crease-resisting properties of the material, and the impregnated and baked material is then subjected to treatment with a scouring liquid to remove some of the resin and thereby to increase the strength and durability of the material.  The scouring treatment may be effected with a hot dilute alkaline solution, or a cold dilute mineral acid, such as hydrochloric acid, or a warm dilute solution of an organic acid such as formic, acetic, or oxalic acid.  Several scouring treatments may be given, e.g. an alkaline scouring may be followed by an acid scouring.  The fabric is preferably treated so that after curing, it contains 10-15 per cent of resin, calculated on the dry weight of unfilled cloth, and that after the scouring treatment it contains 6-8 per cent of resin.  Sodium carbonate of 0.2-5 per cent strength or caustic soda of 0.1-2 per cent strength may be used at or below boiling temperature.  In an example, linen fabric which has been treated with caustic soda of mercerizing strength and allowed to shrink in the width, is dried and then impregnated with an aqueous solution of a urea-formaldehyde condensation product containing a small proportion of tartaric acid. The fabric is squeezed, dried and then baked so as to cure the resin. The fabric, which is relatively stiff, harsh and brittle, is then scoured for 2 hours at 55 DEG  C. in 1 per cent caustic soda solution.  It is finally washed and dried.  The treated fabric is still crease-resistant, but is stronger, more durable and softer than the unscoured resin-treated material.  In another example, the resin-treated and baked mercerized linen fabric is scoured with a dilute solution of acetic acid and sodium acetate at a pH value of 4.5 for 3 hours at 60 DEG  C.  Specification 437,361 is referred to.

Title: Valve arrangement for beer fitting with a check valve inserted between the plunging tap and the pressure equalising conduit
IPC: B67D1/16
Filed: 1927-02-14
Abstract: 281,135. Rogers, F. H., (Roskothen Patent Bierarmaturen Ges.). Feb. 14, 1927. Direct gas and air apparatus, non-automatic. -In beer engines, the check valve inserted between the plunging tap and the pressureequalizing conduit is combined with a pressure equalizing valve. The diaphragm 7 is pressed by a spring 8 bearing against the valve body 1 on a seat 9 with a central aperture 10 which is out of alignment with the apertures 11 in disc 16 which serves as a seat for the check valve 6 with a central aperture 13. When pressure gas is admitted through the channel 14 from the carbon dioxide conduit 5, the gas raises the diaphragm 7, and passing the check valve, forces the beer back from the curved tube 4. If the barrel pressure is higher than the pressure in the pressure gas conduit 5, the valve 7 remains closed as the barrel pressure can only act on a small proportion of its area. In a modification (Fig. 3, not shown) the barrel pressure is conveyed by conduits in the valve casing above the diaphragm 7 thereby assisting the spring in keeping the valve closed.

Abstract: 104,750. Snell, F. W. March 22, 1916. Spray carburettors; vaporizers, external.-In a vaporizing process, the fuel and hot air from a spray carburettor are drawn by engine suction through an atomizer consisting of a succession of chambers and finely perforated diaphragms heated by a medium from the engine, and into a vaporizer heated by the exhaust gases, the vaporizer being supplied with air when required. In the arrangement shown in Figs. 5 and 7, the atomizer a consists of a thin-walled copper tube arranged vertically between the spray carburettor c and the vaporizer b. The walls of the tube a may be corrugated transversely or longitudinally or otherwise shaped to increase their surface and are enclosed by an annular jacket e of badly-conducting material. Hot water from the engine passes by a pipe f to the jacket e, and by a pipe f<1> to the carburettor c. The atomizer is divided into chambers by a series of metal tubes d and interposed perforated diaphragms g. The vaporizer b is formed integral with the main exhaust chamber h and with an air-heating chamber n, from which air passes by a pipe and a flap valve m to the carburettor. A perforated air-admission plate i forms one side of the air chamber n, and the top wall of the chamber n is fitted with an air valve o adapted to admit air from the chamber directly into the vaporizer. The casting b is provided with branches h<4> connecting the exhaust chamber h with exhaust passages from the engine, and with branches h<5> leading to the induction passage of the engine. The vaporizer is secured to the engine by bolts p passing through tubular portions h<6>, h<8>. In a modification, the atomizer is heated by exhaust gases passing from the exhaust chamber through a valve controlled from the car. In another form, in which the exhaust chamber is on the side of the cylinders opposite to the induction passages, an exhaust passage is formed in the vaporizer casting and has an inlet at one end and an outlet to the silencer at the other. The engine may be started on petrol and afterwards run on paraffin, the paraffin and petrol tanks being fitted with supply pipes communicating by means of a three-way valve with a single supply pipe leading to the carburettor.
