摘要： 878,191. Jet-propulsion nozzles. VICKERS AIRCRAFT HOLDINGS Ltd., and RICHARDS, E. J. Oct. 14, 1959 [Aug. 18, 1958], No. 26462/58. Class 110 (3). In a gas-turbine jet-propulsion engine, the jet nozzle outlet has a large width to depth ratio, and the nozzle is combined with an air-induction casing arranged to surround the nozzle and of such a length as to cause ambient air to be drawn in and entrained with the gas discharge. The propulsion nozzle 10 is of circular section at its upstream end 101 and of rectangular section at its outlet 102. The nozzle is enclosed within a nacelle 11, the upper and lower walls of which terminate at 111, while the side walls thereof terminate level with the nozzle outlet 102. The air induction casing associated with the nozzle is shown in its retracted or inoperative position in Fig. 1 in full lines and in its projected or effective position in chain-dotted lines, and comprises upper and lower fairing members 15 and side plates 14 connected together to form an open-ended casing which is disposed around the nozzle 10. The upper and lower members 15 are of aerofoil or tapered cross-section and when in the projected position afford, together with upper and lower edges of the nozzle 10, openings C through which air is drawn to be entrained with the discharging gases thereby producing a noise suppression effect. The side plates 14 of the induction casing are disposed in the spaces between the side walls 112 of the nacelle and the side walls of the nozzle and are supported by means of rollers 13 which are movable in channel-section members 12 secured one to each of the side walls 112. A cable 17 is secured to the rollers 13 and threaded around pulleys 16, the movable element 181 of a fluid-pressure pressure ram 18 being connected to the cable, so that movement of the ram in the direction B causes the induction casing to be moved from the retracted to the projected position. The jet nozzle may be of elliptical instead of rectangular section; also a series of nozzles may be disposed side-by-side, a single induction casing being associated with the nozzles.

摘要： 774,396. Jet propelled helicopter rotors. RICHARDS, E. J. April 1, 1955 [April 23, 1954], No. 11789/54. Class 4. [Also in Groups XXVI and XXVII] A helicopter rotor blade is provided at or adjacent the trailing edge of the tip portion of the blade with an elongated narrow nozzle of fixed configuration in the form of a generally linear slot or other closed figure and means for emitting a propulsive jet from that nozzle. A rotor blade is formed with a spanwise duct 10 formed with chord wise branches 11 which terminate in nozzles 12 collectively arranged to emit a long narrow propulsive jet generated by the combustion of air from the duct 10 and fuel supplied to pipes 14 which inter-connect the nozzles. The nozzle outlets may be deflected downwardly to provide a lift component and the outlet edges of the nozzles may be corrugated to reduce noise. It is stated in the Provisional Specification that rods placed across the outlet of the nozzle assist in reducing noise. In other embodiments the nozzles have the form of circular or elliptical annular outlets from combustion chambers mounted at the tips of the rotor blades.

摘要： 631,785. Aircraft wings. VICKERS-ARMSTRONGS, Ltd., and RICHARDS, E. J. Nov. 25, 1947, No. 31222. [Class 4] In order to delay the formation of compressibility shock waves to the same extent over the whole span of a wing, the angle of sweep back of the quarter chord line is made greater over the inboard region than at the wing tip. The leading edge may be formed with two or more straight portions A1, A2, Fig. 1, having different angles of sweep back or by a smooth continuous curve C, Fig. 3. The trailing edge B may be straight as shown in Fig. 1, or similar to the leading edge, Figs. 2 and 4 (not shown).

摘要： 610,621. Aerofoils; boundary layer control. GOLDSTEIN, S., and RICHARDS, E. J. April 11, 1946, No. 11196. [Class 4] An aerofoil of small or moderate thickness/ chord ratio, and of which the leading edge is sharp or of small radius, is provided with a sharp-edged spanwise suction slot at or very close to the leading edge for applying suction to the boundary layer, Figs. 1 and 1a show an aerofoil with a thickness/chord ratio of 8.6 per cent with a sharp leading edge, the extreme tip of which is truncated by a forwardly facing suction slot S, the width of which is 0.4 per cent of the chord. The slot is connected to a suction pump P through a duct D. A thin symmetrical aerofoil suitable for flight at supersonic speeds is shown in Fig. 5, the thickness/chord ratio being 5.4 per cent, and the width of the suction slot S 1 is 0.26 per cent of the chord. Specification 578,763 is referred to.

摘要： 578,185. Automatic control, systems for electric motors. RICHARDS, W. J., and STEVENS, G. W. H. Aug. 24,1934, No. 24407. [Class 38 (iv)] Speec.-Electric contacts intermittently interrupting the circuit of an electric motor and opened and closed under the control of a spring and a centrifugal mass are additionally controlled by the load torque. Fig. 1 shows the motor shaft 4 carrying the mass 1 on a leaf spring 2 and connected through a torsion spring 9 with the load shaft 10. The shaft 10 carries a cam 7 which is adapted to move one of the contact members 5, 6 and may provide any desired torque-speed characteristic or obtain constant speed at all loads. Fig. 3 shows a mass 11 operating upon contacts 20, 23, pivoted at 12 on a disc on the motor shaft, and controlled by a spring 15 with adjustable anchorage 17 on the disc. The torque loading, is obtained by a prismatic pin 29 engaging the mass at a desired point near the pivot and carried by a crank 30 connected to the load shaft.

摘要： 28,112. Evans, A. J., Jones, T. H., and Richards, J. R. Dec. 19. Copper sulphides.-Copper sulphide is obtained from ores containing atacamite or basic sulphate or compound sulphates of copper, or mixtures of these, with or without other sulphates, by leaching the pulverized ores with a weak hydrochloric or sulphuric acid solution, preferably containing from 2 to 3 per cent. of acid, or a mixture of both, and precipitating copper sulphide from the solution obtained by means of sulphuretted hydrogen. After removing the precipitate, the solution is used for leaching fresh batches of ore, and the precipitate may be converted into the subsulphide of copper by melting. When the ore contains soluble copper salts, such as chlorides or sulphates, it is leached with water, and the copper sulphide is precipitated therefrom by sulphuretted hydrogen, the acid solution remaining being used for leaching fresh batches of ores.

摘要： 890,106. Exhaust silencers. HALL ENGINEERING Ltd., and RICHARDS, E. J. Aug. 29, 1960 [July 17, 1959], No. 24586/59. Class 7(2). A silencer for the exhaust of jet engines comprises a curved rectangular section diverging expansion duct c, Fig. 1, in which the jet is expanded and turned upwards. The tube c at its entry end has an approximately square cross-section which becomes wider and of smaller depth so that at the cross-section 11- 11 it is a wide slot which discharges through a perforated member d into a diffusion outlet c. The inlet end of duct c is provided with an adapter a carried by pivoted, counterweighted arms f so that it can be adjusted to the height of the jet engine. The adapter a is provided with a baffle b Fig. 8 through which air is drawn to enter the jet stream, the parts a, b, being covered with sound absorbing material. Water jets may also be sprayed on to the stream in the conduit c which is pivotally supported on a platform p by a pillar n and struts q. In a modification, Fig. 15, the tube c is carried on a wheeled platform p, which can be raised off its wheels by jacks t, and the height and inclination of the conduit can be varied by adjustable struts x, y.

[Class 38 (i)] [Also in Group XXXIX] In a sealed can for housing electrical apparatus (see Group XXXIX), terminals 13, on a tray 6 carrying components, are carried by an insulating bush 14 extending through a hole in the tray 6, and a cupshaped washer 15 of insulating material caps the projecting end of the said bush, the whole being secured by opening the end of the split terminal shank to form a fork 16. Terminals 20 for making external connections are sealed through the container by metal to glass seals.
