Title: Improvement in aeroplanes
IPC: B64D5/00
Filed: 1933-12-11
Abstract: 430,071. Aircraft carrying other aircraft. BOULTON & PAUL, Ltd., Riverside Works, and NORTH, J. D., Hill House, Eaton, both in Norwich. Dec. 11, 1933, No. 33023/34. Divided out of 429,948. [Class 4] In a compound aeroplane comprising two aircraft elements releasably attached one above the other so that they both assist in the take-off and climb, means are provided for measuring and indicating the forces transmitted through the attachments to enable the pilot to ascertain when the appropriate conditions for safe separation are obtained. As shown, the upper component is connected to the wings of the lower element, vertically above its landing-gear, by quick-release devices. Load-measuring devices to enable the magnitude of the forces and the couples between the two elements to be determined and comprising links 26, 29 and an elastic capsule 31 connected to a pressure gauge and filled with an incompressible fluid, are provided at the attachments. The abutment 33 prevents undue movement, a second capsule may be provided for indicating the presence of compressive forces at the attachments and in this case the pressure sensitive devices at each joint may be connected to a differential pressure gauge. The pressure gauges are provided with needles, the rotational movement of which indicate the nature of the forces at the attachments. The three needles may be on a single dial, marked at at 37, 38 so that from their intersection within the circle safe conditions for release may be indicated. The fluid capsules may also actuate wards 45 having keyways 49 co-operating with keys 42 on a plunger 39 held in position by a key 43, against the action of springs to provide automatic means for ensuring safe release. The compound aeroplane may be controlled in the manner described in Specification 429,948.
Patent GB-748879-A (GB)
Title: Improvements in or relating to the production of solid non-ionic surface active agents
IPC: F16K3/02
Filed: 1952-12-31
Abstract: A liquid non-ionic surface-active agent comprising a compound having in the molecule a chain of condensed ethylene oxide groups is converted into a solid form of improved colour by treating the liquid agent with an excess by weight of solid urea in the presence of a reaction diluent and, as a reaction activator, a compound which has a solvent action on urea, maintaining the mixture until urea adduct formation has taken place and separating the solid product, the pH of the reaction mixture when tested as hereinafter described being initially within the range 2.5 to 7.0. The pH is that of a test sample of the reaction mixture after its dilution with water to give a 1 per cent solution of the surface-active agent.  The urea employed may contain biuret.  The term "reaction diluent" denotes a liquid hydrocarbon which does not form a urea adduct or a mixture of hydrocarbons containing only a small proportion of hydrocarbon which forms urea adducts at the temperature of the reaction, the diluent being a non-solvent for urea and the surface-active agent.  The required pH may be established by addition of an acid to one or more of the reactants or to the reaction mixture; acid anhydrides may be used when water is present.  Suitable acids and acid anhydrides include sulphuric, hydrochloric, phosphoric, formic, acetic, oxalic and aromatic sulphonic acids, carbon dioxide, acetic anhydride and phenols.  Preferably, the stated pH is maintained throughout the reaction.  The surfaceactive agents mentioned and the general conditions of the adduct formation are as set forth in the parent Specification.  Reaction activators include glycerol, ketones such as acetone and methyl ethyl ketone, C1-3 alcohols and water; specified diluents are n- and iso-pentanes and hexanes, cyclopentane, cyclohexane, and 40-150 DEG  C. petroleum ethers.  In an example, "Lissapol NXA" (Registered Trade Mark) is treated with sufficient acetic acid so that the prescribed test gives a pH value of 6.5, and then reacted with urea in n-pentane and methanol, the solid product being light in colour as compared with the product obtained similarly but at a pH of 9.4.  The surface-active agents described in Specification 748,881 may also be so treated.  According to the Provisional Specification, liquid non-ionic surface-active agents generally may be converted into solid form by reaction with urea, the pH of the reaction mixture being initially within the range of 2.5 to 9.5.

Abstract: 994,751. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. Sept. 22, 1961 [Sept. 24, 1960; Nov. 16, 1960 (2)], No. 34040/61. Heading H4D. A radio beacon comprises two linear spaced aerial arrays disposed about an axis, the respective angle included between the line of each array and the axis being equal, and means to successively energize each aerial in the respective arrays cyclically at the same speed in such a way as to simulate two radiation sources having a Doppler modulation pattern which is symmetrical about the axis. In the beacon of Fig. 1 each array I, II, is several wavelengths long and a wave of frequency F 1  is swept sinusoidally at a frequency F N  across array I; a wave of frequency F 1 +10 kc./s. is swept at frequency F N  across array II in anti-phase motion to that of array I. The frequency deviation of the mean beat frequency between the received waves at a given point defines a series of locii according to the relationship sin # 1 +sin # 2 =a parameter K. In other embodiments the aerial arrays are each inclined to the line joining their centres at an angle γ and the relative phase shift between the simulated motions on the arrays is 2#; a reference phase is transmitted by amplitudemodulating one carrier wave and at the receiver the resultant phase # of frequency deviation at the frequency F N  is compared with the reference phase obtained from the carrier wave which is amplitude-modulated. In Fig. 2, y = 0 and # = 45 degrees. Other geometrical relationships are described with reference to Figs. 3, 4 and 5 (none shown). It is stated that conventional V.O.R. receivers may be used with the beacon. An auto-pilot may be actuated by the error signal produced when travelling off a predetermined equi-phase line utilized as a course-approach track.
