Title: Fluid servo powered actuator
IPC: F02C3/10
Filed: 1967-04-24
Abstract: 1,139,273. Gas turbine engines. BENDIX CORP. April 24, 1967 [May 6, 1966], No. 18726/67. Heading F1G. [Also in Division G3] A fluid servopowered actuator for the stator blades 40, Fig. 1, of a road vehicle gas-turbine engine comprises fluid-pressure responsive means 114, Fig. 5, controlled by a valve 126 actuated by a lever 152 provided with a cam follower 168 resiliently urged in engagement with a contoured cam surface 170, a second reverse contoured cam surface 212 being engaged by a second loaded cam follower 214 to nullify the torque due to the first follower. The fluid-pressure responsive means 114, Fig. 5, is operatively connected to the movable stator blades 40, and is connected to the means 114 by a position feedback lever 152 and by means 170, 206, 204 &c. to a lever 79 for adjusting the turbine output, the action of the feedback lever being overridden during vehicle deceleration so that the means 114 causes the stator blades to retard rotation of the gas turbine. The lever 79 is coupled to the vehicle accelerator and rotates the cam 170 through gearing 204, 206 to cause the lever 152 to pivot about the point of engagement between a follower pin 118 and a projection 116 on the means 114. The valve 126 which has a curved bearing member 150 in engagement with the lever 152 is thus raised to connect a supply port 62 to a space 120 and a vent 76 to a space 122 so that the means 114 is displaced to the right until the feedback has restored the valve 126 to its null position. A pump 82 driven from the turbine supplies fluid under pressure through a line 84 to a port 86 to lift a ball 180 when the vehicle speed reaches 15 m.p.h. The ball 180 lifts a further ball 178 through a rod 177 to a position in which it is just clear of the lever 152 so that it forms a pivot for the latter when reverse rotation of the cam 170 occurs during subsequent deceleration of the vehicle, the pin 118 being separated from the projection 116 and the valve 126 displaced downwards to admit fluid from port 62 to the space 122 until movement of the means 114 is arrested by a stop 93. The torque acting on cam 170 is balanced by providing a ball 216 which is subjected on one side to vent pressure through passage 108 and on the other side to pressure from the space 122 and acts on the second cam 212 through the follower 214. The followers may have tips similar to those of ball point pens. During rapid acceleration, the relationship between stator blade position and that of the lever 79 is linear while more gradual acceleration produces a non-linear relationship.

Title: Improvements in or relating to the production of surface active agents
Filed: 1950-07-28
Abstract: Surface-active salts are prepared by contacting a long-chain alkyl hydroperoxide or an alkyl-substituted naphthene hydroperoxide or mixtures thereof, with sulphur dioxide in the presence of an aqueous and/or alcoholic medium and an amount of an inorganic or organic base such that the hydroperoxide or mixture of hydroperoxides is converted to a neutral salt of an alkyl hydrogen sulphate and/or a neutral salt of an alkyl-substituted naphthene hydrogen sulphate.  The expression "long-chain alkyl hydroperoxide" refers to the compounds R.OOH, where R is an alkyl group and where the sulphate RO.SO2.OX, X being an alkali metal, is surface-active; R preferably contains 10-20 carbon atoms and is a C12-16 alkyl group when detergent products are desired.  The hydroperoxides are generally reacted upon at -10 DEG to 100 DEG  C.  The sulphur dioxide may be used in liquid or gaseous form and at normal, reduced or elevated pressure. Suitable bases are alkali metal hydroxides, alkanolamines such as ethanolamines and butanolamines, pyridine, morpholine and ammonia. The hydroperoxides may be prepared by oxidation of suitable hydrocarbon stocks following similar procedure to that described in Specification 695,547.  In an example, a kerosine cut B.P. 210-220 DEG  C. is air-oxidized, extracted with methanol to remove the hydroperoxides and the extract concentrated; the concentrate is dispersed in aqueous caustic soda and treated with SO2 yielding an aqueous solution of surface-active agent.

Title: Method and device for modulating the intensity of a luminous source particularly applicable to television and like systems
IPC: H04N5/66
Filed: 1926-07-31
Abstract: 256,611. Tawil, E. P. Aug. 7. 1925, [Convention date]. Television apparatus.-The intensity of a beam of light is controlled electrically by utilizing the variations in shape or optical properties of a piezo-electric crystal to which the varying potential is applied, the arrangement being such that the beam is incident directly on the surface of the crystal. To obtain maximum effects the current used may be of a frequency corresponding to the natural frequency of the crystal. In the arrangement of Fig. 1, light from a source S is concentrated by a lens C on a very narrow slot f in a screen e, and a second lens L<1> produces an image of the slot at I of a size comparable with the elongations of the quartz plate Q of which one end is arranged in the plane of the image. The degree of interception of the rays is thus varied in accordance with the variations of length of the plate, and a third lens L<2> concentrates at P the light of varying intensity. In a modification. Fig. 2, the light is reflected from the surface of the plate Q, and the lens L<2> concentrates the reflected rays at P. Two or more plates may replace the single plate Q. In the arrangement of Fig. 3 the end of the plate Q extends into a parallel beam from a source S<3> and a lens L' to vary the length of shadow on a slot extending between B and B<1>. Fig. 4 shows the use of a quartz plate Q<5> fixed between end stops H, H<1> so that the potential variations produce a curvature of the plate. A parallel beam from a source S<5> and a lens L<5> is reflected by a mirior M on the plate, and the beam reflected by the plate, of varying divergence in accordance with the curvature, is incident on a perforated screen G. The light passing through the screen is thus of an intensity dependent on the degree of divergence of the beam, and is concentrated at P by a lens L<2>. The use of interference phenomena by arranging a reflecting surface on the quartz plate to constitute one of two Fresnel mirrors, and the use of double refraction phenomena in connection with the deformations of the plate, are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement shown in Fig. 4 (Cancelled), comprising two quartz plates secured together, the inner sides being earthed by a wire d and the outer sides being connected to the variable potential circuit d<1>. The resulting deformations are used, to vary the light reflected from a beam T by a mirror m. This subect-matter does not apjpear in the Specification as accepted.

Title: Variegated glass sheets and processes and apparatus for the manufacture thereof
IPC: C03B13/10
Filed: 1937-07-10
Abstract: 481,148. Making ornamental plates or sheets of glass. FISHER, H. A. July 10, 1937, No. 19187. [Class 56] [Also in Group X] A plate or sheet of glass is ornamented by embedding therein continuous or discontinuous lines or ribbons of glass of a different colour or appearance, the embedded glass being exposed on one surface of the sheet. In making the sheet, streams of coloured glass are delivered on to a newly-made sheet of glass while it is still plastic, or on to a mass of glass before it is formed into a sheet, the applied glass being rolled into the surface of the sheet. The sheet-forming machine may be of the kind in which molten glass is teemed on to a casting-table T, Fig. 5, and is flattened bv moving the table under a flattening-roller R and trailer rollers R<1>, R<2>. The coloured glass is contained in a pot 42, Fig. 2, which runs on rails above, and parallel with, the table T. The glass is applied to the sheet by means of a gathering-bar 40 having cranked extensions 46 and provided on its lower edge with one or more teeth 45. The bar is placed in the glass in the pot 42, and is then lifted out and supported on pivoted rests 50, the position of the bar being between any of the rollers, as shown in Fig. 5, or above the mass of glass in front of the roller R. The bar may be reciprocated transversely of the table either by hand or by means of a rotating eccentric 56, Fig. 2, and the glass that runs off the teeth forms wavy lines on the glass sheet, the lines being embedded in the surface of the sheet by the rollers. More than one gathering bar may be used, or it may be replaced by a metal cylinder or drum, of perforated material, which is dipped into the pot 42 and is rotated and reciprocated when in position above the sheet. The roller may be arranged to deliver the decorative glass in interrupted lines or spots. In another modification, streams of the decorative glass flow from apertures 91, Fig. 11, in the bottom of a pot 90, into funnel-shaped passages 96 in a bar 95 which is reciprocated similarly to the bar 40. The passages 96 receive the streams of glass and distribute them in the required manner on the surface of the sheet. Air or steam jets may be used to break up the streams of glass and project them in finely-divided form, or as glass wool, on to the surface of the sheet.

Abstract: 478,133. Electric incandescent lamps. RADIOAKT.-GES. D. S. LOEWE. July 10, 1936, No. 19199. Convention date, July 12, 1935. [Class 39 (ii)] An electric incandescent projection lamp, more particularly for use in television transmitters, is adapted for use upon a multiphase alternating current supply by providing it with as many separate filaments as there are phases in the alternating current supply, the filaments being connected to one phase each of the supply and arranged side by side in the plane normal to the direction of projection. The filaments may be in either star or delta connection. In the example three filaments 1-3, supplied from star-connected transformer windings are arranged side by side in front of a spherical reflector 7 within the lamp bulb (not shown), so that an actual image of each filament is projected to one side thereof and within the space between the filament and the adjacent filament. The lamp is adapted to be included in a television transmission system such that the frequency of the filament current supply is synchronous with the movement of the film and the scanning, and may amount to an integral multiple of the number of image changes.
