Filed: 1951-02-02
Abstract: 706,984. Aircraft wings and stabilising surfaces. BOULTON PAUL AIRCRAFT, Ltd. Jan. 30, 1952 [Feb. 2, 1951], No. 2704/51. Class 4 In an aircraft wing or the like, or part thereof, adapted-to be pivotally attached to the aircraft to permit variation of the angle of sweep, the wing or the like is of such a shape near the axis of rotation as to form a solid or solids of revolution about said axis. The wing or stabilizing surface 1 is pivoted at 4 to the fuselage 5, the root portions 8 and 9 being formed as solids of revolution 2 and 3 about the point 4, the respective sections of the solids being determined by the sectional profiles 6, 7 of the wing. at the lines of intersection with the fuselage when the wing is respectively in its fully forward swept and fully rearward swept positions. By this means a uniform clearance and simplified sealing between the root portions of the wing and the openings in the fuselage is ensured.

Title: Improvements in or relating to Apparatus for Providing a Reading Dependent on the Density of a Gas or Vapour
Inventor: JANSSEN SYLVAIN JEAN
IPC: G01N9/20
Filed: 1967-01-18
Abstract: 1,173,091. Measuring the density of gas, electrically. COMPAGNIE DES COMPTEURS. Jan.18, 1967 [Jan.21, 1966], No. 2772/67. Headings G1N and G1S. An apparatus for measuring the density of gas or vapour into which the apparatus is immersed comprises a balance beam 11 Fig. 1 carrying at one end a hermetically sealed hollow glass sphere 10 upon which a buoyancy thrust is exerted by the gas. A known type detector 14 (not described) senses deviation of the beam 11 due to the thrust and an amplified signal is fed to a coil 12, carried on the opposite arm of the beam to the sphere 10, which coil co-operates with a magnetic core 13, including a permanent magnet 13a to restore the beam to equilibrium. The magnitude of the restoring current in the coil is measured, as a measure of the gas density. To counteract unbalancing of the beam caused by parasitic deposits, a second hollow sphere is carried by the other end of the beam Fig. 3 (not shown), the gas to be measured being freely admissable to the interior of the second sphere, and deposits which may occur on both spheres are mutually neutralized. Alternatively there may be two similar balance beams (not illustrated), one beam carrying an unsealed hollow sphere and measuring the weight of deposit only. In a further embodiment Fig. 4 (not shown), instead of the second sphere, the beam 11 carries a disc the total surface area thereof on which condensate and dust may settle being equal to the surface area of the sealed sphere; also a dummy coil may be placed on the opposite arm of the beam to the restoring coil to neutralize deposits thereon. Balance beam mounting. The beam 11 may be of glass or crystal and is carried by a stainless steel rocker 15 Figs. 1, 2 which is suspended by non-magnetic steel torsion bands 16 stretched between two tensioning springs 17. The bands 16 also carry the current to the coil 12. Cylindrical rods 27, Fig. 2 are provided to limit horizontal and vertical movements of the beam.

Filed: 1916-02-25
Abstract: 124,513. Freeth, F. A., and Cocksedge, H. E. Feb. 25, 1916. Potassium and sodium nitrates. - Potassium nitrate is recovered from commercial sodium nitrate by digesting the sodium nitrate with water or wash liquors at a temperature of about 80- 100‹ C., and, if the solution, is not saturated with potassium nitrate, concentrating the solution until it is so saturated, the precipitated sodium nitrate being separated and washed; the solution saturated with potassium nitrate is then diluted with water until the ratio of the water to the sodium nitrate is the same as that which would obtain in a solution saturated with sodium and potassium nitrates, at the temperature to which the solution is to be cooled, for instance about 20‹ C. ; and the solution is then cooled to that temperature. Potassium nitrate separates and is removed and washed. The mother-liquor and, if desired, the washings of the sodium nitrate, may be concentrated till saturated with potassium nitrate at the temperature of concentration, and then treated as before to obtain more potassium nitrate. The washings of the potassium nitrate may be concentrated until saturated with potassium nitrate at the temperature of concentration and then cooled to obtain a further separation of potassium nitrate.

Abstract: 1,243,054. Valves. ROTAX Ltd. 6 Jan., 1969 [22 Jan., 1968], No. 3223/68. Heading F2V. [Also in Division G3] A fluid flow control valve comprises a housing having an enlarged portion 11 intermediate its ends, a hollow body 13 within the enlarged portion and having a closed end 15 and an open end, a piston 16 slidable within the hollow body and having an integral skirt 17 slidable within the housing, a seating 23 at the open end of the hollow body, a valve element 22 intermediate the ends of the skirt for co-operation with the seating, a flow aperture 24 in the skirt, and means for causing movement of the piston within the hollow body between a closed position in which the flow aperture lies within the body and an open position in which the flow aperture is exposed beyond the body. Pressure from the upstream side of the valve 8 is admitted through a solenoid-actuated valve 26 and a restriction 27 to a space 25 to displace the piston 16 to the right and open the valve. If the solenoid valve is operated to connect the space 25 to atmosphere, pressure at the outlet 9 acting on the piston 16 and at the inlet 8 on the annular area between the reduced portion of the skirt 17 and the valve element 22 causes the valve to close. A change-over valve 28 permits the inlet and outlet 8, 9 to be reversed and also maintains the valve open if the pressure drop is reversed. The piston 16 may be spring-biased towards either the open or closed position of the valve which may be used to control the downstream pressure by connecting the space 25 with the end 8 of the housing through a pressure regulator. The valve may be used to control the air flow to a pressurized aircraft cabin.

[Class 103 (i)] Modified annular brake discs of the kind described in the parent Specification comprise in one form Figs. 2, 3 a flange 7 adapted to be bolted through holes 31 to a vehicle wheel hub or axle and on which is cast the disc proper comprising a pair of rings 19, 20 connected by radial braces 21. A series of relatively thin radial vanes 25 disposed between successive braces extends inwardly from each ring towards the other and are of tapering width radially inwards as shown by the inner edges 28 thereof so that the total unobstructed cross-sectional area for the outward radial flow of air effected by the braces is substantially constant. Air passing through radial slots 18 in the flange 7 passes over the braking surface 10 which is relatively close to the wheel to effectively cool that surface. Heat is also conducted from the brake surfaces 10, 11 by the vanes and braces. The flange is corrugated as at 16 to give flexibility and it has dovetail notches in its edge for anchoring it to the ring 19. In another construction, the braces 108, Fig. 7 which as in Figs. 2, 3 are of the same radial depth as the vanes 109, are of X-form providing passages 110 therein. In this form, the flange corresponding to the flange 7, the rings 104, 105. and the vanes and braces 108, 109 form a single casting. In a further form, an intermediate ring 209, Figs. 11, 12, 14 is integral with thick radial braces 208 and thinner races 210. A space 212 may be formed in the vanes to facilitate the flow of air. An additional support which may be provided for the disc comprises an annular web 214 with radial projections 217 engaging the ring 206, and an outer ring 219 engaging the outer brake ring 207 and connected to the web and projections by radial webs 218. These webs are in alignment with the braces 208. This support is secured to the wheel to be braked by the same bolts 212 that secure the flange 201 of the brake disc.

The plate may have a pin which engages in an arcuate slot in the retaining plate fixed to the ski and retained in central position by a detent device or the detent ball may engage in an arcuate slot in the plate. The hold down elements 14 may be vertically adjustable. A toe hold down member may be adjustably mounted on a screw or supporting angle plate, the base may have a thread which adjustably engages a complementary thread on the plate 6. The jaw plate may be mounted on the plate 6 and retained with one rectilinear edge engaging an edge of a plate fixedly secured to the ski over the plate 6, the jaw plate being released to rotate when the plate 6 moves longitudinally or a hook on the ski may engage a recess in the rear edge of the jaw plate or a rod pivoted on the pivot of the plate 6 may engage a cut out at the rear edge of the jaw plate.
