Title: Apparatus for steering air-craft
IPC: B64C3/54
Filed: 1920-07-09
Abstract: 148,177. Flettner, A. July 23, 1918, [Convention date]. Addition to 148,308. Steering and balancing.-In the invention described in the parent Specification, a pair of auxiliary planes is provided to each steering- plane of an aircraft, one auxiliary plane assisting adjustment of the steering-plane in one direction, and the other in the opposite direction. In the case of ailerons, according to the present invention, one of the pair of auxiliary planes is provided in connexion with one aileron, and the other in connexion with the opposite aileron. In the form shown in Fig. 2, an aileron f is provided with an arm g to which is pivoted the auxiliary plane h and a link k which is formed with a lug @ and connected by a rod l to the main plane e. When the aileron is raised, the downward movement of the arm g causes the lug i to bear against the auxiliary plane and adjust it so that the air pressure thereon assists to raise the aileron. When the lever g moves upwards, the auxiliary plane hangs free; a spring n avoids swinging of the plane under these conditions, a lug o limiting the action of the spring.

Patent GB-340983-A (GB)
Title: Improvements in and relating to dyes including intermediates and to dyeing
IPC: C09B9/02
Filed: 1929-07-01
Abstract: Anthranol sulphuric esters are obtained by treating anthranol p (anthrone) or a substitution product thereof with a tertiary base-sulphuric anhydride compound in the presence of a tertiary base. The anthranol derivatives used as starting materials may be made by reducing the corresponding anthraquinones with copper and sulphuric acid.  If amino groups are present in the anthranol derivative they are protected by acylation, e.g. acetylation, before esterification, the acyl groups being subsequently removed if desired.  The preparation of sulphuric esters of a - and b -acetylamino-, a - and b -amino-, 2-acetylamino (or 2-amino) - 3 - chlor -, and b  - sulphoanthranols, and also of anthrone itself and 4-chlor-9-anthrone, is described in examples.  The products may be used as colouring matters, and in a further example wool is dyed a brown shade with the sulphuric ester of the 2-amino-3-chlor derivative; on treating with acid oxidizing agents, such as ferric chloride in dilute sulphuric acid, a deep chocolate brown dyeing is obtained.  Azo dyes; azo dyes, forming on the material.-The sulphuric esters of aminoanthranols yield azo dyes on diazotizing and coupling, in substance or on the fibre, with amines or phenols, including arylides of oxynaphthoic acids.  The azo dyes may be used with esters of vat dyestuffs in the same way as the products of Specification 333,506, [Class 2 (iii), Dyes &c.], and the dyeings may be after-treated with oxidizing agents.  In examples, the sodium salt of the sulphuric ester of b -aminoanthranol is diazotized and coupled with b -naphthol; the product dyes cotton a blueish-red shade, which changes to orange on treating with acid ferric chloride.  Indanthrones and flavanthrones; vat dyes, dyeing with.-The sulphuric esters of aminoanthranols may be converted into dyestuffs of the indanthrone or flavanthrone type by treating with oxidizing agents, in substance or on the fibre.  In an example, a brown dyestuff, which appears to be a sulphuric ester of a body of the indanthrone type, is obtained by treating the sodium salt of the sulphuric ester of b -aminoanthranol with sodium hypochlorite. On treating with dilute mineral acids, in substance or on the fibre, this brown dyestuff is converted to a less soluble blue dyestuff; when the treatment is carried out on the fibre, a blue dyeing is obtained changing to a bright pink with acids.  On treating the brown dyestuff with chromic acid and sulphuric acid, a greenish yellow product is obtained, which is converted to a blue vat dyestuff with reducing agents.  If the sulphuric ester of b -aminoanthranol is treated in substance or on the fibre with acid oxidizing agents, without previously treating with alkaline oxidizing agents, dyestuffs of the flavanthrone type are obtained, flavanthrone itself being apparently produced by treatment with acid cupric chloride or acid ferric chloride.

A tandom actuator for aircraft control surfaces comprises stationary pistons 13, 14 and a moving cylinder 10 which carries valves 23, 23a controlling the movement thereof and a pivot 26 for a differential level 25 controlled by the pilot through lever 29. The latter is coupled at 32 to piston actuators 33, 33a controlled electrically from auto-pilot or auto-stabilizer 36 via monitors 37, 37a, demodulator-amplifier units 38, 38a, selector valves 34, 34a, and pilot valves 35, 35a. The actuators provide electric feedback to the monitors and the d-a units and the monitors function to break the electrical connection to the respective valves if the input and feedback signals vary unduly. Under these circumstances, if the left-hand channel fails, no fluid is supplied to actuator 33 and the piston 42 therein is locked between spring-loaded plungers 44. A spring box 34' allows continued control by actuator 33a. A similar reaction is obtained for the left-hand fluid supply at 21 fails. If the right-hand supply fails a valve 52 inter-connects opposite sides of the piston of actuator 33a to allow continued control by actuator 33. Valves 24, 24a relieve excess load-induced pressures in cylinder 10.

Abstract: 499,649. Electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 22, 1937, No. 20323. Convention date, July 22, 1936. [Class 39 (i)] In electron multipliers having an end collector electrode 21, secondary emitting surfaces 5, withdrawing electrodes 9 and a magnetic field parallel to the surfaces 5 the electrodes being biassed positively to the thermionic cathode 29, the latter is surrounded by a magnetic shield 33, which prevents the magnetic field acting on the emission from the cathode and interfering with control by the grid 41. A positively-biassed screen grid 85 between the control grid and the multiplier electrodes prevents effects from changes in bias on these electrodes reacting on the thermionic emission. The control grid 41 or the screen grid 85 may be supported by the shield 33 or independently. The cathode comprises a thimble with emissive coating 31 and heater 27. The biassing potentials are such that each electrode 9 is positive to that secondary emitting electrode which is below it; it may have the same potential as that under the adjacent electrode 9. Specification 469,477 is referred to.

Abstract: 140,140. O'Brien, A. M. Dec. 13, 1918. Hydrocarbons, distilling; progressive evaporators.-In a plant for the continuous fractional distillation of petroleum and other liquids by passage through a series of stills, the stills are made of successively diminishing capacities, the several capacities being proportionate to the fractions of the total quantity of liquid which undergo treatment in the respective stills. The plant may be arranged so as to yield quantities of distillates bearing a constant proportion to the quantities of liquid treated in each still, in which case the capacities of the stills form a geometrical series. The capacities of the stills may be also determined on the basis of an experimental test of the liquid to be fractionated. The dimensions of the condenser tanks are proportional to the distillates from each still, and the condensing-water may be led through the condenser tanks in succession. As shown in plan in Fig. 1, the stills A may be arranged on the same level with their backs in the same plane, so that their fronts present a step-wise formation and the furnaces B<1>, B<2>, B<3> can all be seen at once by the workman.
