Title: Processes for the preparation of esters by direct synthesis from  alcohols and carboxylic acids
IPC: C07C69/24
Filed: 1969-06-26
Abstract: 1308137 Esters ALBRIGHT & WILSON Ltd 26 June 1970 [26 June 1969] 32223/69 Heading C2C A water-insoluble ester is prepared by reacting an alcohol with a carboxylic acid thereby forming a reaction product comprising ester and unreacted carboxylic acid, treating the reaction product with an aqueous solution of an alkali in the presence of an alkali metal or alkaline earth metal salt of an aryl or alkaryl sulphonic acid to give an organic phase and an aqueous phase and separating the phases. The salt is suitably sodium xylene or toluene sulphonate. The ester is suitably formed from a monohydric alcohol and a di- or mono-carboxylic fatty acid such as lauric, linoleic or stearic acid. The sulphonio acid corresponding to the sulphonate may be used as a catalyst for the esterification reaction. After separation of the phases the aqueous layer may be acidified to form a fatty acid layer and an acidified aqueous layer, the former being recycled to the esterification and the latter being recycled to the alkalinification stage.

Title: Radio aerials
IPC: H01Q5/45
Filed: 1971-07-30
Abstract: 1330175 Aerials ELLIOTT BROS (LONDON) Ltd 30 July 1971 [4 Aug 1970] 37684/70 Heading H4A An aerial includes a twist-reflector assembly in which a plurality of grids, each comprising an array of parallel conductors, are arranged in front of a reflector, with the conductors of all grids parallel. The admittances of the individual grids, and the spacings between them and to the reflector are such, that at each of a plurality of operating frequencies, the respective admittances of the assembly to mutually perpendicular components of a predetermined plane polarized wave incident upon the assembly are of relatively inverse magnitude and of opposite sign. As described, a twist-reflector comprises two copper wire grids 5, 6 mounted in front of a continuous aluminium back plate 7. Each grid is formed by bonding the wires to a dielectric skin. Lowdensity dielectric foam sheets are then bonded between the skins, and between the innermost skin and the backplate, to maintain spacings D1, D2. In use, the twist-reflector is arranged with the wires of the grids 5, 6 at 45 degrees to the electric vector of an incident wave. The spacings between the wires of the grids, and the distances D1, D2 are selected so that at two predetermined frequencies the electric vector of the emergent wave is at 90 degrees to that of the incident wave. In application to a Cassegnain type aerial, Fig. 1, not shown, a feed horn projects through a twist-reflector of the kind described, and radiates plane polarized waves towards a parabolic trans-reflector having strips or wires which are parallel to said plane of polarization, and which may be embedded in a fibreglass honeycomb provided with front and rear dielectric reinforcing skins. The transreflector collimates the waves received from the horn, and reflects them towards the twist-reflector, which re-reflects them with their plane of polarization turned through 90 degrees, so that they then pass through the trans-reflector. Scanning may be effected by tilting the twistreflector.

Abstract: 1350084 Control of servomotors RANK ORGANISATION Ltd 30 Dec 1971 [18 Feb 1971] 4959/71 Heading H2J A servomechanism for moving a load between limiting stops comprises an A.C. or D.C. servosystem 1, which may include an amplifier, a servomotor or similar actuator and a tachometer generator, an input 2 receiving the demand signal at 8 through an input circuit 3 and an attentuator and/or amplifier circuit 9 which receives a load-position signal from a potentiometer 7 coupled to the load and which controls the circuit 3 such that as the load reaches a critical position before an end stop, the voltage applied to the input 2 is reduced to a preset maximum value to reduce the servo output speed. The circuit 3 includes an amplifier 4 in whose feedback path are located transistors 10, 11, diodes 12, 13 and resistor 14, the latter five members being equivalent to a switch in series with a voltage source, Fig. 1 (not shown), which switch is open during intermediate positioning of the load and is closed when the critical position is reached to limit the output voltage of amplifier 4 to that of the voltage source. This limiting continues until the output voltage falls below that of the source, whereupon the voltage at input 2 follows the falling amplifier output voltage. Below a certain lower value the switch opens. Reversal of the signal at input 8 allows the servo to drive the load at full speed from the stop. Control of circuit 3 is such that one or other of transistors 10, 11 is switched on at chosen points determined by the resistor chain of circuit 9 which may be omitted if desired, the transistors then being controlled by an attentuated signal from the potentiometer 7. The value of resistor 14 may be altered to change the speed of the servo as it reaches the transistor "switch-on" point, Fig. 4 (not shown). Potentiometer 7 may be replaced by a resolver. The gain of the circuit 3 is discussed with respect to leakage and offset currents produced by the members 10 ... 14. The limiting voltage source is simulated by the sum of the voltages across the transistor 10 or 11 which is turned on, its diode 12 or 13 and the common emitter resistor 14.
