Title: Improvements in or connected with the construction of aircraft wings
IPC: B64C3/00
Filed: 1935-06-27
Abstract: 458,789. Aircraft wing structures. VICKERS (AVIATION), Ltd., PIERSON, R. K., and BEWSHER, J., Byfleet Road, Weybridge, Surrey. June 27, 1935, No. 18409. [Class 4] In a stressed skin aircraft wing in which the skin is attached to upper and lower members spaced apart by bracing members the upper member is permanently attached to the bracing members whilst the lower member or a portion thereof is detachably secured to the bracing members by means of fastening-devices, the skin forming the underside of the wing being permanently attached to the said lower member in such manner that the said fastening-devices are accessible from the exterior of the wing. In one form, a two-spar wing has ribs comprising girders e, f, which may be of channel section, and Warren-girder bracing c. During construction the ribs are formed in a jig but lower flange f is not permanently attached to bracing members c, the lower apices of these latter being constituted by blocks g to which flange f is adapted to be connected by screws. In assembly rib flange d is riveted to upper surface skin e and then permanently attached to the spars. The skin e may extend around the leading part of the wing, in which case nose riblets j are provided permanently attached to flange d and the skin lower flange f is riveted to lower skin panel i and is then attached to blocks g and to the spars by countersunk screws. The forward edge of panel i, rear part of riblet j and forward part of rib flange f are joggled as shown to enable the forward end of panel i to fit inside skin e. According to a modification ribs with flat plate webs may be employed ; in this case blocks g will be suitably spaced and attached to the plate web. The lower panel need not extend the full distance between front and rear spars. The form of construction described may be employed for wings having only one spar. Specification 314,376, [Class 4], is referred to.

Title: An electrical system for checking the random character of sequences of symbols
IPC: H04L9/22
Filed: 1963-05-10
Abstract: 1,042,981. Checking random sequences. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 10, 1963 [May 10, 1962]. No. 18529/63. Heading G4D. The randomness of a sequence of symbols is checked by comparing the number of symbols produced in a cycle with the number of first appearances of symbols. A key generator 1 of the type described in Specification 954,313 can select from 32 letters. Each signal is counted at 2. The first occurrence of each letter sets a related storage device d1-d32 so that only the first occurrences are counted at 3. When 3 reaches full capacity it adds one to counter 4 and restores the storage devices, simultaneously starting a new cycle of generator 1. Counters 2 and 4 are set to predetermined numbers so that if the number 4 is attained before that in 2 then a bi-stable device 5 is reversed to operate an alarm 6. Otherwise the device 5 is restored. The alarm 6 may operate only if it receives a high enough proportion of signals from 5 for each cycle (Figs. 3-5, not shown).

Title: Improvements in or relating to the production of cellulose esters
IPC: C08B3/00
Filed: 1953-07-10
Abstract: <PICT:0740171/IV(a)/1> Cellulose is continuously esterified in homogeneous phase by continuously treating cellulose with esterifying agents in the apparatus of Specification 626,067, [Group IV (b)], the casing of the apparatus being provided with inlet and outlet ducts for the reactants and the temperature of the reaction mixture being controlled.  As shown in the example, cellulose impregnated with twice its weight of acetic acid is continuously fed at a rate of 150 kg. per hour (dry cellulose weight) into the inlet 2 of the casing 1 of the reactor, together with 300 litres per hour of glacial acetic acid.  A mixture of 500 parts of glacial acetic acid, 9 parts of 66 DEG  B<\>e. sulphuric acid and 360 parts of 97 per cent acetic anhydride is introduced continuously through pipes 11 and 12 at the rate of 870 litres per hour.  Water is circulated through the jackets 7-10 so that the temperatures in these jackets are 12 DEG , 20 DEG , 40 DEG  and 55 DEG  C. respectively.  A hollow shaft 5 is cooled by circulating through it water at 12 DEG  C.  The reaction mixture travels through the mixing zone between the inlet 2 and pipe 11 in 7-15 minutes, and from the pipe 11 to the outlet 3 in 15-20 minutes. The reaction mixture discharged from the outlet 3 is directly pumped into a mixing apparatus into which 450 litres per hour of a mixture of 60 per cent of acetic acid and 40 per cent of water is continuously pumped.  A solution of cellulose triacetate in acetic acid is thus obtained.  Cellulose propionate, butyrate and acetobutyrate may be similarly prepared. The cylindrical casing 1 of the reactor has internal surface projections in the form of ribs 4 and surrounds a hollow concentric shaft 5 having an interrupted worm thread of separate paddles 6 arranged in a spiral.  Underneath the inlet 2 the shaft 5 is provided with a continuous helical screw-thread 13.  The shaft 5 is both rotated and axially reciprocated with respect to the casing 1.

Title: Apparatus for mass transfer between two phases
IPC: B01D47/02
Filed: 1961-05-29
Abstract: In apparatus comprising an exchange chamber in which two different phases are brought into intimate contact with each other so that a substance passes, at least partially, from one phase into the other phase, a mechanical pump is used to convey at least one of the <PICT:0973748/C1/1> phases to a mixing device in which the phases are contacted with each other before they flow into the exchange chamber, and a centrifugal separator is employed to separate the phases after they leave the exchange chamber. The apparatus may be used for washing carbon dioxide out of synthesis gas with a liquid, for liquid/liquid extraction processes e.g. extracting uranyl nitrate from an aqueous solution by means of ether, and for isotope exchange reactions e.g. deuterium exchange between liquid ammonia and gaseous hydrogen. The column 20 contains a series of units (of which only two are shown), each suitable for mass transfer between a liquid phase and a gaseous phase. Each unit comprises an exchange chamber 26 provided with baffles 28, an ejector 27 which serves as the mixing device, a pump 22 driven by an electric motor, a liquid level vessel 25 having an overflow conduit 24 to the next lower unit, and a centrifugal separator 23. The starting liquid phase is introduced into the vessel 25 of the top unit, and the starting gaseous phase flows into the bottom of the column. Pump 22 draws in gas from the space between two units and discharges it through nozzle 31 into the ejector 27; and liquid is drawn into the ejector from vessel 25. The mixture of liquid and gas passes out of the ejector into the exchange chamber 26. After mass transfer has taken place, the mixture passes through tangential nozzles 29 into centrifugal separator 23. The separated liquid flows down to vessel 25, and the separated gas is drawn into the pump of the unit above. Some of the liquid in vessel 25 flows down conduit 24 into the vessel 25 of the unit below. If a unit should break down during operation, e.g. owing to a motor fault, the gas flows to the next higher unit through by-pass 21.

Title: Improvements in or relating to a process for treating petroleum hydrocarbons
IPC: C10G53/12
Filed: 1950-08-03
Abstract: In a process for recovering straight chain hydrocarbons from a petroleum fraction of gas oil boiling range by contacting the fraction with urea in the presence of water, to form solid adducts containing urea and straight chain hydrocarbons, the petroleum fraction is first contacted with an adsorptive solid or with a strong inorganic acid having a proton-donating ability at least as great as aqueous 90 weight per cent. sulphuric acid.  This pretreatment removes inhibitors for adduct formation such as heteropolycyclic sulphur compounds.  Adsorptive solids referred to are silica gel, activated alumina, bauxites, silica-alumina, silica-magnesia, charcoal, bone-black, activated carbon, magnesium silicate, kieselguhr, infusorial earth, diatomaceous earth, and clays such as fuller's earth, bentonite and Attapulgus clay.  Acids specified are sulphuric acid, hydrogen fluoride, hydrogen fluoride - boron trifluoride, and hydrogen chloride-aluminium chloride.  After treatment with acid, the oil may be washed with alkali, for example aqueous sodium hydroxide, or a volatile acid may be stripped from the oil.  The petroleum fraction may be diluted with diluents such as butane, pentane, isopentane, isooctane, neohexane, benzene toluene, xylene, cyclohexane and methylcyclohexane.  The urea adduct may be decomposed by contacting with a urea solvent such as water, by heating above its melting point, by distilling under vacuum, or by heating with a diluent.
