Title: Supersonic aircraft
Inventor: SHAW RONALD ANDREW
IPC: B64C1/38
Filed: 1956-03-01
Abstract: 849,212. Cooling aircraft structure ; boundary layer control. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Feb. 21, 1957 [March 1, 1956], No. 6529/56. Class 4. The surface of a very high speed aircraft is cooled by a liquid, e.g. a fuel, which flows rearwardly thereover and enters the intake of one or more gas turbine or ram jet engines where it is burnt to provide thrust. In the aircraft of Fig. 1, the leading edges of the delta wing 1 are formed by a strip 3 of liquid-pervious material, e.g. perforated or slotted sheet or sintered metal sheet, the strip forming part of the wall of a duct 4 supplied with fuel through a pipe 6, Fig. 3. Further liquid-pervious strips 7, 8 may be provided above and below the wing to emit additional fuel. As the fuel flows rearwardly it is evaporated in the boundary layer and enters the intakes of gas turbine engines 13 disposed along the wing trailing edges. The intakes extend above and below the wing to an extent greater than the thickness of the boundary layer so that practically all the fuel emitted on the surface is utilised in the engines. The fuselage 2 may be similarly cooled by liquid-pervious sections 14, 15. Figs. 5, 6 (not shown) show aircraft with swept back or swept forward wings, the engines being situated at the wing tips or wing roots where the boundary layer tends to converge so that the fuel emitted on the wing surface enters the engine intakes. A further engine may be mounted on the end of the fuselage to receive the liquid emitted thereon. Thermocouples in the surface of the wing may control the liquid emission. It is stated that fuel evaporating in the aircraft boundary layer, will, by its cooling effect, promote luminar flow.

Title: Improvements in hardness measuring apparatus
IPC: G01N3/42
Filed: 1952-03-13
Abstract: 701,954. Hardness testing : pneumatic gauges. SOC. D'APPLICATIONS ET DE CONSTRUCTTONS POUR MATERIEL AUTOMOBILE. S.A.C.M.A. March 13, 1952 [March 17, 1951], No. 6575/52. Class 106 (2) In an apparatus for measuring the hardness of a piece by means of a ball or cone &c. driven into the piece by the action of a diaphragm subiected to the pressure of a gaseous fluid, hardness is determined by measuring, by means of a pneumatic device, the displacement of the diaphragm under the effect of a given pressure, and is characterized in that the same source of gaseous fluid at constant pressure supplies the fluid acting upon the diaphragm and feeds the pneumatic measurement device. A supply of compressed air is maintained at constant pressure in a pipe 74, Fig. 2, by a head of water H. After passing through a calibrated nozzle 82, the air is fed by a pipe 36 to a chamber 16 beneath a diaphragm 19, Fig. 1. which incorporates a ball 20, supporting a rod 21 embodying a conical diamond 22 which is applied to the surface of the workpiece 9. Two air leakages are provided in the chamber 16 ; a small calibrated leakage 33, Fig. 2, and a larger aperture 38, Fig. 1, which, when closed by manually depressing a lever 40, causes pressure to build up beneath the diaphragm 19 and force the conical point 22 into the workpiece. The pressure in the chamber 16 is indicated by a hydrostatic gauge 79. Pneumatic gauging of the depth of the impression is performed by a device 29 incorporating a plunger 28 spring-urged to maintain contact with a plunger 27 which follows the movement of the ball 20. This movement adjusts the effective leakage aperture to atmosphere between the conical end 54 of the plunger 28 and its seating 55. Compressed air is supplied to the gauge via a calibrated nozzle 71 and the pressure in the chamber 58-which is related to the size of the leakage aperture and therefore to the depth of the impression in the workpiece -is indicated by a hydrostatic gauge 72. Means are described for adjusting the position of the gauge for zeroizing, and for adjusting the height of the workpiece support 8.

Title: Improvements in cigarette mouthpiece feed
IPC: A61F13/20
Filed: 1959-02-27
Abstract: 912,503. Making cigarette mouthpieces. AMERICAN MACHINE & FOUNDRY CO. Feb. 27, 1959 [April 22, 1958], No. 6967/59. Class 130. Multiple length, e.g. sextuple length, mouthpiece rods are fed on to a fluted drum 44, Figs. 1 and 2, on which they are carried first past a device 72, e.g. an air nozzle, which moves them laterally against a stop 64, and then past a knife 78 which subdivides them, the subdivided portions being delivered on successive rotations of the drum on to a chain conveyer 84, the empty flutes being then recharged. In Figs. 1 and 2 the rods are delivered down a shoot 28 from which they are picked up in succession by three rows of teeth 38 on a wheel 94. The number of flutes 46 on the drum 44 is one more or less than a multiple of three (twenty-three as shown) and the sextuple length rods are delivered by the wheel 94 into every third flute on the drum 44 so that after three revolutions of drum 44 all flutes contain mouthpiece material and as flutes become empty they are refilled by a sextuple length rod. The knife 78 cuts a double length stub off the end of each rod, which stubs are delivered on to conveyer 84, and on the next revolution of the drum the remaining quadruple length portions of the rods are moved by the nozzle 72 against stop 64 so that they are positioned for bisection by knife 78. The lefthand bisected portions are then delivered on to conveyer 84 and in the next revolution the remaining portions are moved to the left by nozzle 72 so that they are finally discharged on to conveyer 84. The stop 64 comprises a member 62 rotated by pins 66 on drum 94 and provided with stop faces synchronized with the flutes 46, two of the faces having recesses 70 which permit the final subdivided section in each flute to be blown such a distance to the left that it is completely clear of the knife 78. In a modification. Fig. 3, the sextuple length rods are fed to a fluted wheel 118 on which they are subdivided into three double-length stubs by a pair of knifes 120, the subdivided rods being transferred into every third flute of drum 144 on which they are drawn sideways by a suction box 132, Fig. 5, against a stop 134 and delivered singly on to conveyer 140. In Fig. 6 the multiple length rods are fed through a shoot 146 into successive flutes of drum 152 under the control of a cam-actuated gate 148 which closes after all the flutes are filled and remains closed for the next two revolutions. The rods are blown by an air nozzle against a stop 222 and cut by a single knife 188 as in Fig. 1. The stop 222 is moved backwards slightly by a cam 232 to permit the last stub length of each rod to clear knife 188. When the empty flutes reach shoot 146 on the third revolution the gate 148 is reopened by a cam 168, acting through lever 164, to permit re-filling of the flutes.

Filed: 1950-03-21
Abstract: 670,912. Cathode-ray oscillograph circuits. DU MONT LABORATORIES, Inc., A. B. March 21, 1950 [June 9, 1949], No. 7040/60. Class 37. A two-gun C.R.O. is provided with variable potential tapping means in association with a push-pull sweep voltage or deflection amplifier whereby the standing or D.C. bias voltage on one or both sweep-plate pairs may be adjusted So that the two spots corresponding to each gun are coincident, i.e. one is superimposed upon the other. In Fig. 1 the anode load of valve 21 comprises a pair of parallel connected resistors 24, 25 and similarly the anode load of valve 22 comprises a pair of parallel connected resistors 27, 28. In operation the deflecting plates 13 associated with gun 11 are fed with anti-phase voltages and with D.C. beam biasing voltages from tappings 31, 32 on resistors 24, 27, respectively. The tappings 31, 32 are ganged to move together so that as tap 31 moves towards the anode of valve 21 the tap 32 moves away from the anode of valve 22, thus by operating the gang control the D.C. standing voltage impressed across plates 13 is readily adjusted. The whole arrangement is duplicated in the case of plates 14 associated with gun 12 by likewise provision and connection of taps 33, 34 on resistors 25, 28 so that there is independent control of each spot, whereby both may be brought into coincidence. In a modification, Fig. 2 (not shown), a single resistance with two tappings, one fixed and one variable, is used as part of the anode load for each valve in place of the parallel combination shown in Fig. 1. The " home position of one spot is fixed by the fixed tappings and the variable tappings provide for position adjustment of the other spot to secure the same " home" position for both spots.
