Title: Improvements in Apparatus for Measuring the Tilt or Radial Acceleration during Turning Movements of Aeronautical Machines and for Compensating the Effects of such Tilt or Acceleration on Compasses.
IPC: G01C9/08
Filed: 1916-09-26
Abstract: 110,565. Starling, S. G., Hughes, A. J., and Hughes & Son, H. Sept. 26, 1916. Accelerometers.-Apparatus for use on aircraft for measuring the tilt or radial acceleration during turning movements makes use of the fact that the apparent weight of a body suspended on the aircraft is increased during such movements. Figs. 1. and 2 show a weight 8 carried by a bar 1 suspended by a spring 3 from a frame 6, the bar 1 working in guides 2 and being connected by a link 4 to a pivoted pointer 5 capable of moving over a dial 7. The weight 8 becomes subjected to centrifugal force when the aircraft moves in a curved path, and, owing to the accompanying tilt of the aircraft and of the apparatus shown, the resultant of this force and of the force due to gravity acts in the axis of the spring. The spring consequently becomes extended and the pointer moves over the dial to indicate the tilt or radial acceleration. In a modification the weight is suspended from an horizontal arm which is pivoted at its other end to a supporting bracket and is maintained in position by a spiral spring. The arm carries a pointer moving over a dial. In a further modification, Fig. 5, two weights 8, one on each side of the median line of the aircraft, are supported by a cord 14 which passes over pulleys 15 and is secured to a pulley 16. The spindle of the pulley 16 is connected to a supporting bracket 18 by a spiral spring 19 and carries a pointer 5 which moves over a dial 13. The difference between the radial accelerations to which the weights are subjected, due to the difference in radius of the paths of the weights when the aircraft turns, causes the pointer to move and to travel to the right or left according to the direction of tilt.

Patent GB-712698-A (GB)
Title: Improvements in or relating to gas detectors
Inventor: KRONBERGER HANS
IPC: G01N1/00
Filed: 1951-06-12
Abstract: An apparatus for detecting, or measuring the concentration of, a gas in a gas mixture compises a thermal diffusion column, means for feeding the gas mixture across one level of the column, a gas detection or concentration measuring device coupled at another level in the column and means for feeding the gas at said other level through the detection or measuring device.  In the preferred apparatus shown in the Figure and designed for detecting a heavier gas in a mixture (e.g. an organic vapour in oxygen) the column 4 is in the form of concentric tubes whereby an annular diffusion space is formed.  Gas from the pipe 1 enters this space through conduit 2 due to the convection current set up by electrical heating coil 8 about the exit conduit 3.  It passes through a wire gauze 19 in order to avoid interference with the diffusion circulation set up in the column by means of the cooling jacket 15 surrounding the outer wall 12 and electric heating element 17 within the inner wall 13.  The heavier component is concentrated in the lower part of the column and detected by means of the detector 7 which may be a katharometer.  It is drawn through said detector by means of convection due to heating coil 10.  According to the Provisional Specification the pressure is maintained constant by means of a valve in the pipe 1.  The inner wall is "optimized" to the gas constants (viscosity, density, temperature) by means of steps and centred by three screws (one shown), 21.  Thermocouples 22 and 23 indicate the temperature of the walls.  If the apparatus of the invention is to be used with a contaminant lighter than the main gas, the mixture is fed <PICT:0712698/III/1> in at the bottom level and detected at the top, in the case of two impurities of which one is lighter and one heavier than the gas, the mixture is fed to the central portion of the column and the p  impurities detected at each end.  Applications are mentioned.

Title: Improvements in and relating to tetrahydrofurane derivatives
IPC: C07D307/00
Filed: 1958-05-02
Abstract: Amines of the tetrahydrofuran series of the formula <FORM:0881520/IV (b)/1> wherein R3 is an alkyl radical of up to 4 carbon atoms, a cycloalkyl radical of up to 6 carbon atoms or a mononuclear aryl or aralkyl radical are prepared by reducing the corresponding 3-oxo compound with an alkali-metal borohydride, preferably in the presence of a water-soluble tertiary amine such as triethylamine and, if substantially pure stereoisomers are required, separating into fractions, after vacuum distillation if desired, by adsorption chromatography.  The products may be converted into quaternary salts by reaction with a reactive ester of an alcohol R4.OH (R4=C1-4 alkyl or C1-3 alkenyl) such as a halide, sulphate or aryl sulphonate, and these quaternary salts may be treated to interchange the anion, for example an iodide anion may be replaced by chloride by reaction with silver chloride.  The preparation of stereoisomers by chromatographic adsorption is suitably effected on an aluminium oxide column from a non-polar or slightly polar solvent, e.g. benzene or ether followed by elution with a similar solvent to which a gradually increasing amount of a lower alkanol may be added.  The invention also comprises a process for the isolation of a halide of (+)-muscarine by reacting a racemic muscarine base with dextro-rotatory di-p-toluyl-L-tartaric acid in a lower alkanol or alkanone and splitting the resultant (+)-muscarine-(+)-di-p-toluyl-L-bitartrate, e.g. by treatment with HCl.  Specified products include 2-methyl-, 2-phenyl-, 2-benzyl-, 2-cyclopropyl and 2-isobutyl-, 3-hydroxy-5-dimethylaminemethyl-tetrahydrofuran and the various stereoisomeric forms of normuscarine and muscarine and their salts.
