Title: New benzenesulphonyl ureas and process for their manufacture
IPC: C07C311/54
Filed: 1962-06-22
Abstract: The invention comprises compounds of the formula: <FORM:0953097/C2/1> in which X is oxygen or sulphur and R1 is a saturated or unsaturated aliphatic or alicyclic hydrocarbon radical of 2 to 8 carbon atoms, with the exception of n-propyl and n-butyl, or is an alkyl or cycloalkyl radical of 4-8 carbon atoms, interrupted by an oxygen and/or sulphur atom or is a benyyl or b -phenethyl radical, and salts of these compounds with physiologically tolerable bases.  The compound are made by standard methods for the preparation of sulphonyl ureas e.g. by reacting a benzenesulphonyl isocyanate, carbamic ester, carbamic halide or mono-thiocarbamic ester or a benzenusulphonyl urea, N1-acyl urea or bis benzenesulphonyl urea with an amine R1-NH2 or conversely by reaction of a benzenesulphonamide with an isocyanate R1NCO, a carbamic ester R1-NH-COOR2, wherein R2 is alkyl or phenyl, or a carbamic halide.  The sulphonyl ureas may also be made by forming a benzenesulphonyl isourea ether, benzenesulphonyl guanidine, benzenesulphonyl parabamic acid or benzenesulphony thiourea and converting these by known means such as hydrolysis or oxidation into the desired sulphonyl urea. Products are specified in which R1 is a cycloheptyl, isobutyl, cyclooctyl or cyclohexyl group. N-(4-Trifluoromethoxy - benzenesulphony)-N1-cyclohepty thiourea is made by reaction of 4-trifluoromethoxy - benzenesulphonamide with cycloheptyl mustard oil.  4-Tribluoromethylthio - benzenesulphonamide is made by diazotising trifluoromethyl 4-aminophenyl sulphide and reacting the product with sulphur dioxide and cuprous chloride in glacial acetic acid to give trifluoromethylthio - benzenesulphonyl chloride which is then treated with ammonia. Methyltrifluoroemthoxy-benzenesulphony -urethane is prepared by reaction of 4-trifluoromethoxy-benzensulphonamide and chloroformic ester.  N-Trifluoromethoxy - benzenesulphony - N1-acetyl urea is made by the action of acetic anhydride on trifluoromethoxy-benzenesulphonyl urea.  N,N-diphenyl-N1-cycloheptyl urea is prepared from dephenyl carbamoyl chloride and cycloheptylamine. Pharmaceutical preparations for oral treatment of diabetes mellitus comprise the above compounds of the invention in admixture or conjunction with a carrier, preferably in the form of a tablet.

Title: Improvements in or relating to aircraft controls
Inventor: STRANG WILLIAM JOHN
IPC: B64C13/00
Filed: 1953-09-02
Abstract: 748,094. Aircraft ailerons. BRISTOL AEROPLANE CO., Ltd. Aug. 27, 1954 [Sept. 2, 1953], No. 24323/53. Class 4. A fixed wing aircraft has ailerons 11, each operated by at least one servo tab 12, and resilient means urging each aileron downwardly so as to reduce or eliminate the tendency of the aileron to be deflected upwardly from the position in which it forms a smooth continuation of the wing, when the aileron is left free to set itself in normal flight. As shown, the aileron is formed with a portion 13 penetrating into a compartment in the wing 10 and, with a flexible sealing strip 15, divides the said compartment into two parts communicating with the upper and lower surfaces of the wing. The flap 12 is similarly arranged on the aileron. A torsion bar 18 extending parallel to the pivot axis 14 has one end fast with the aileron, and the other journalled in a bearing 22 in the portion 13 and fast to a link 19 pivoted to a further link 20 pivoted to the wing at 21, so that deflection of the aileron twists the torsion bar 18. When the aircraft is stationary or at landing or take-off speed, the bar 18 deflects the aileron to its downmost position, giving high lift. In normal flight, the aileron if left free, assumes a position which renders it a smooth continuation of the wing. The torsion bar assists in mass balancing the aileron.

Title: Apparatus for automatically maintaining a fixed angle or parallelism between two optically flat surfaces
IPC: G01B9/02
Filed: 1962-06-27
Abstract: 974,378. Photo-electric inspection. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. June 27, 1962 [July 25, 1961], No. 24709/62. Heading G1A. [Also in Division G3] Two optically flat partially transparent surfaces are maintained at a fixed relative attitude by automatically adjusting them so that a beam of light passed through them in one direction and returned to pass through them at the same angle in the opposite direction is transmitted with minimum loss. Fig. 2 shows a Fabry-Perot interferometer in which one plate 1 is mounted relative to a frame 26 by three piezo-electric supports such as 23, and the other plate 2 is similarly mounted by piezo-electric supports 20, 21, 22 relative to a member 33 which is manually adjustable along rods 27, 28, 29 relative to a frame 26 by nuts 30, 31, 32. Collimated light from a source 6 is directed by a prism 16 through the right hand portions of plates 1, 2 and reflected by inclined surfaces such as 12 at the rear of plate 2 so that the beam is returned at the same angle through the lefthand portions of the plates to a photomultiplier 11A the output of which serves to control piezo-electric devices such as 23 to automatically position plate 1 about a vertical axis for maximum output of photomultiplier 11A. In a similar manner light from a source 10 is directed through the upper portions of plates 1, 2 and reflected by inclined surfaces such as 14 so that the second beam is returned through the lower portions of the plates to a photomultiplier 11 which controls piezo-electric devices such as 23 to position plate 1 about a horizontal axis for maximum output of photomultiplier 11. The piezoelectric devices, which are prepolarised by heating with an applied electric field, are of barium titanate laminated between multiple electrodes. After manually adjusting nuts 30, 31, 32 so that the photomultiplier outputs are approximately maximum as indicated by meters, an oscillator is switched on to supply piezo-electric devices 20, 21, 22 through a phase splitting device so that plate 2 is oscillated at small amplitude about both its axes. If the resulting oscillations of the photomultiplier outputs are not symmetrical about maxima, outputs at oscillator frequency having phase senses corresponding to the errors are produced. These outputs automatically control E.H.T. applied to piezo-electric devices such as 23 to eliminate the errors and thus maintain the plates parallel. The automatic control may be superposed on continuous drive of member 33 along rails 27, 28, 29. Optically flat control plates may be fixed to plates which are opaque or which have to be maintained at a fixed relative attitude other than parallel. Alternatively a transparent wedge may be inserted between plates to be maintained at a fixed relative attitude other than parallel. The Specification also refers to splitting a single beam of light after transmission through the plates and returning the two beams so produced through the plates at different positions.
