Abstract: 718,498. Controlling boundary layer flow. STEPHENS, A. V. Oct. 23, 1951 [Oct. 24, 1950]. No. 25886/50. Class 4 A substantially impervious boundary surface relative to which when in use a fluid medium moves, is provided with a conformation for dividing up the boundary layer of the medium into side by side sections and diverting alternate sections away from the surface, thereby to project them into the medium some distance away from the boundary surface itself, while allowing the remaining sections to expand laterally into the spaces adjacent the boundary surfaces from which the first mentioned sections have been diverted. A plurality of excrescences 2 of generally triangular plan-form are arranged in one or more rows transverse to the direction of fluid flow. Their bases 3 face the direction of flow 4 and their apices 5 are raised above the level of the boundary surface 1, and they are spaced apart so that the distance 8 between each pair is a fraction, and preferably one-sixth, of the width of the base 3. The sides 6 may be curved in substantially S-form and the excrescences may be solid with the apices forming a knife-edge or they may comprise a plate surface supported by a central web. The portions of the boundary layer that flow over the surfaces of the excrescences 2 are deflected away from the boundary surface 1 the remaining portions that pass between the excrescences 2 being free to expand laterally with a corresponding reduction in thickness. The rows of excrescences may be positioned on an aircraft along the leading edge of a wing or ahead of a control surface such as a flap or an aileron or on the fuselage adjacent the roots of the wings. The excrescences may be hinged along their bases 3 so that the height 7 of the apices may be adjusted and when they are associated with control surfaces this adjustment may be operatively connected to the surface control mechanism. In an aileron, the leading edge thereof may be serrated and the trailing edge of the wing adjacent thereto formed with corresponding serrations so that when the aileron is deflected excrescences as shown in Fig. 1 may be formed. Other applications to motor vehicles, diffusers, ships hulls and propellers for ships and aircraft are described.

Patent GB-371273-A (GB)
Title: Improvements in or relating to the production of lubricating oils and lighter hydrocarbons by the hydrogenation of hydrocarbons
Filed: 1931-09-19
Abstract: Lubricating oils and light hydrocarbons are produced by hydrogenating hydrocarbons and <PICT:0371273/III/1> hydrocarbons, or material capable of liberating either of these, is supplied from a main 102 by line 103 to the coil 7.  The mixture passes by line 11 into a reaction drum 13 supplied with hydrogen by line 106; the temperature can be controlled by adding cold material from pipe 6<1>, or by means of a coiling coil 88.  The material is kept in circulation by a pump 87; the products pass out by line 14 and valve 16 to a vaporizer 17, kept at reduced pressure (below 50 mm.) by a vacuum pump 18.  Vapours leave by line 19 and are passed to fractional condensers 5, 5<1>, and a barometric condenser 23.  Gaseous fractions are purified in the system 26, 28, and recirculated to the hydrogen main by line 31.  The residues in the vaporizer 17 are withdrawn by line 39 to a receiver (not shown).  Liquid from condenser 5 may be passed back by line 40<1> to the vaporizer.  According to a modification, the residues are passed to a tank 55 and then by lines 56, 58, preferably through reheating tubes 59 to a subjecting all the products to vaporization at sub-atmospheric pressure.  Hydrocarbons withdrawn from a tank 1 are pumped through a preheater 4 by line 6 to heating and reaction coils 7 .. 10, of the type described in Specification 359,023 and 359,024: the section 10 may contain catalyst.  Hydrogen, or gaseous second vaporizer 60, maintained at a lower pressure than the first. Vapours from the second vaporizer are fractionated in the usual system 61, 61<1>, 69 to yield lubricating oils; the residues are withdrawn by pipe 62 to a receiver 152.  In another modification condensate from the condenser 5 is passed to a tank 111 and thence through reheating tubes 115 to a third vaporizer 116, maintained at a pressure intermediate between those of vaporizers 17, 60.  The residues pass to a receiver 155 or by a line 121<1> to the tank 55. The vapours are fractionated in the usual manner.  In a third modification the hydrogenated products are separated from gaseous and low boiling products before passing to the vaporizer 17.  If the initial feed stock contains light fractions, it is pumped through lines 6, 89 into a tray 91 in a steam-heated still 90.  The light fractions are passed by line 94 to the vaporizer 17, or are condensed separately; the residue is fed to the coils 7.
