Title: Improvements in or relating to instruments for indicating the direction of a magnetic field
IPC: G01C17/28
Filed: 1929-12-05
Abstract: 332,507. British Thomson-Houston Co., Ltd., (Assignees of Pickard, G. W.). Dec. 6, 1928, [Convention date]. Magnetic tests and measurements.-An instrument for indicating the direction of a magnetic field includes a member the resistance of which changes with angular movement with respect to the magnetic field. It is found that the resistance of certain materials varies with changes of flux density through them. The nickel-iron alloy known as permalloy, containing 78 to 80 per cent. of nickel, is stated to exhibit this property to a marked extent. Fig. 5 shows a construction of compass for steering aeroplanes. Four permalloy wires A - - D are arranged as shown on a rotatable spider of non-magnetic material having channels in which the wires are sealed by insulating material. The wires A - - D are connected at their ends to binding posts 41 - - 44 which are connected to slip-rings 29 - - 32. Brushes 25 - - 28 are so connected to a battery E and galvanometer G that the wires A - - D form the four arms of a Wheststone bridge. When the spider is arranged so that the magnetic field M is parallel to the arms A, C, these arms are of maximum resistance and the arms B, D are of minimum resistance. The bridge is preferably arranged to be balanced when the arms A, C are at 45‹ to the direction of the field, so that opposite movements of the bridge with respect to the field cause opposite deflections of the galvanometer needle. The spider is situated at a position remote from the motor, for example at the end of one of the wings of the aeroplane, and is controlled from the instrument board by means of a setting-wheel and cords passing over pulleys. The spider is preferably mounted in gimbal bearings to avoid errors when climbing or descending.

Title: Sugar esters
IPC: C07H13/12
Filed: 1959-11-18
Abstract: The invention comprises salts of dicarboxylic acid hemi-esters of sugar carbamic acid esters.  The novel products may be obtained by reacting a sugar carbamic acid ester with a dicarboxylic acid and converting the hemi-ester into its salt.  The reaction may be effected in a solvent, e.g. dimethyl formamide, with heating. Suitable dicarboxylic acids anhydrides are maleic, succinic and phthalic anhydrides.  Examples of sugar carbamic acid esters are the reaction products of sucrose, maltose, lactose or raffinose with isocyanates, such as stearyl, cetyl, myristyl, dodecyl or phenyl isocyanate as described in Specification 827,358.  Alkali metal carbonates are generally used to convert the acid esters into their salts.  In a modification, a sugar carbamic acid ester is reacted with maleic anhydride and the salt of the acid ester formed is converted into the salt of the sulphosuccinic acid hemiester, e.g. with sodium bisulphite.
