Filed: 1966-08-11
Abstract: Disazo dyes of the general formula <FORM:1117698/C4-C5/1> wherein a, b and c are H or CH3; SO3M is ortho, meta or, when c is not present, para to the azo group; M is H, alkali metal or an ammonium group; a1 and b1 are H1CH3 or a C1- 2 alkoxy radical; a11 is H1Cl or a C1- 4 alkyl radical and b11 is H or CH3 are prepared by conventional diazotization and coupling methods.  The intermediate monoazo dyes may contain an aminomethane sulphonic acid group which may be hydrolysed to an amino group using NaOH and in the absence of a sulphonic acid group in the prepared intermediate, the intermediate mono-azo dye may be sulphonated.  Alternatively the corresponding disazo dye may be sulphonated to give the SO3H group.  The dyes give yellow-orange shades on wool, silk and especially nylon carpets at pH values above 6.

Title: Improvements relating to the revolving wings or blades of aircraft
IPC: B64C27/48
Filed: 1933-12-21
Abstract: 434,017. Aircraft with rotary wing systems. KAY GYROPLANES, Ltd., KAY, D., and DYER, J. W., 18, Atholl Crescent, Edinburgh. Dec. 21, 1933, No. 36025. [Class 4] In a revolving wing system each wing is capable of flapping motion in a substantially vertical plane and, in the plane of rotation, of lateral movement which is limited by the co-operation of one or more pins interconnecting the wing and the hub or a part associated therewith with one or more bushes engaged by the pins and arranged either in the hub or in a part associated to the latter. The root 2 of each blade terminates in a fork which is attached to a link 4 mounted on a sleeve 5 forming the central part of a built-up hinge pin constructed as described in Specification 285,213, [Class 114]. The blade root is carried by a sleeve 3 mounted on the link 4 and held in position by caps 17 secured together by a bolt 19. The jaws of the fork are formed with oppositely located holes which register with holes at the centre of circular recesses in the link 4 which are lined with metallic bushes 12. The bushes are surrounded by bushes 11 of pliable material such as rubber, felt or fibre. Bolts 10 which which are a tight fit in the holes of the fork are a relatively loose fit in the sleeves 12 and are held in position by a flat spring 13 engaging recesses in the heads of the bolts. In an alternative arrangement, Fig. 6, each recess in the link 4 houses a rubber casing which has a number of independent spaced cavities 22 containing an oily non-volatile liquid such as glycerine together with a soft abrasive powder such as the whitening used as the basis of putty. The blade may be moved towards the fuselage by removal of the bolts 10 and rotating the wing until two opposite holes register with a different hole in the link, the pins 10 being replaced to hold the blade in the folded position. To provide additional positions for the wings further holes may be provided in the link 4. In a further construction, Fig. 7 (not shown), the end of the link 4 is formed with six holes equidistantly spaced on the circumference of a circle and carrying a packing as described in the previous constructions. The two holes in the fork of the blade are spaced to register with any two consecutive holes in the link to provide alternative folded positions for the wings.

An electron gun, particularly for a travelling wave tube comprises a hollow cylindrical cathode 2 having a tapered conical end 4 which end is truncated to provide an aperture 5, an electron emissive coating 6 on at least part of the interior surface of the cathode, means such as heater wires 7 for heating the cathode, and an accelerating anode 15 having an aperture 17 aligned with the cathode aperture 5 so as to produce a hollow beam of electrons. As shown the heater wires 7 are embedded in refractory insulating material 9 in a heat conserving shield 8 and an apertured screen 18 is provided between the anode and the cathode to minimize electron emission from the external surface of the cathode, the opening 19 being slightly larger than the opening 5 to minimize heat conduction to the screen 18. The screen is operated at cathode potential. The electron beam is collimated by the field from a magnetic coil 24 which also co-operates with the cathode in producing a hollow beam. For this reason the shield 8 and cathode body are made of tantalum or of other metals which are non-magnetic at operating temperatures.

C34 connected in groups, each chamber having a vapour-inlet conduit 30 and each group comprising a plurality of chambers disposed at diminishing height and maintained at successively increasing temperature and pressure in the direction of decreasing elevation, the chambers of one group being elevationally interspersed with those of one or more other groups, the chambers of each interspersed group being interconnected by downcomer conduits 46 by-passing the chambers of the other groups, and a riser 50 with a pump P B  ... P F  being provided between each group for pumping the cooling liquid (and condensate) from the lowest chamber of one group to the highest chamber of the succeeding group. Column 22 has two groups of chambers (A) C34 ... C26 and (B) C25 ... C17. Pump P A  raises cooling liquid to chamber C34; and pump Pc transfers cooling liquid and condensate from the base of column 22 to the top of column 20. The chambers C in column 20 are arranged in four groups. Each chamber C contains a distributor 40, a perforated plate or packing, just below the liquid-inlet. Voids or spaces 37 are provided between some of the adjacent chambers. When the condenser system is employed to condense the vapours evolved from saline water undergoing multistage flash evaporation, the cooling liquid may be a hydrocarbon oil. The flash evaporation is carried out in five columns 10, 12, 14, 16, 18 divided by partitions 26 into chambers E1 ... E34 maintained at descreasing pressure. Saline water mixed with hot oil enters the lowermost chamber E1 of column 10 through conduit 60 and flows successively through chambers E1 ... E34 via U-tubes 32, 32a each of which extends from the bottom of a chamber E to just below the demister 28 in the next chamber. The mixture of saline water and oil flows upwards in column 10 from chamber El to chamber E13, and then flows through cross-over U-tube 32a to the uppermost chamber E14 of column 12 whence it passes successively through the uppermost chambers E15, E16, E17 of columns 14, 16, 18 respectively. The mixture of water and oil then flows down from column to column as indicated by references E18, E19 ... E34. The water-vapour evolved in chamber El passes into condenser chamber C1 via the connecting conduit 30; and the vapour evolved in the subsequent chambers E is condensed in an associated chamber C. The condensate, i.e. desalinated water, and hot oil are withdrawn from chamber C1 Unevaporated saline water and cool oil are withdrawn from chamber E34. A series of cycles may be provided to increase the salinity of the unevaporated saline water to a point where various salts will precipitate out.
