Title: Improvements in or relating to a method and apparatus for the photogeodetical production of maps from overlapping oblique terrestrial or aerial photographs
IPC: G01C11/00
Filed: 1921-01-08
Abstract: 157,236. Gasser, M. Sept. 25, 1915, [Convention date]. Photographic surveying.-Relates to the production of contour maps by projection from a pair of overlapping oblique aerial or terrestrial photographs, the apparatus comprising means for setting up the projecting apparatus so that they occupy positions corresponding to those of the cameras at the moments of taking the photographs and projecting on to a common verticallyadjustable horizontal plane. Each photograph includes images of three points whose geodetical positions are accurately known and from these images are determined the height of the camera above the ground and also the co-ordinates of the point vertically below the camera at the moment of taking the photograph. The two projection devices 15, 16 are set up in corresponding positions to scale on a support 12 to which they are attached by universal adjustments, the calculated datum points being represented by the centres of ball joints 20, 21. The devices 15, 16 include reflecting prisms 18, 19 to facilitate their being brought into close proximity if necessary. Mounted in conjunction with each projection device is an observing appliance comprising a telescope 29 having an objective at each end and a single central eyepiece, the telescopes being mounted so as to be universally rotatable about the ball joints 20, 21. The photographs are set to the correct inclination by adjusting each of the devices 15, 16 until each of the known points I, II, III marked to scale on the projection plane is seen in the telescope 29 in coincidence with the corresponding point on the photograph. On now projecting alternately from the two photographs, or by operating shutters &c., certain points will appear steady on the projection plane, and by joining these a contour line is obtained. By raising or lowering the projection plane by the adjusting-means 33, a series of contour lines can be thus drawn. The heights of individual points can also be obtained by the use of two extensible arms 34, 35 pivoted at the points 1, 3 vertically below the datum points 20, 21. These arms are adjusted until the images of the same point on the two photographs fall on their extremities 10, 11. The height of this point is then obtained from the position of the point of intersection of the projecting rays, which is read off on a. graduated rod 30 at the point of intensection of the arms 34, 35. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the sterogrammetric apparatus forming the subject-matter of Specification 183,145, [Class 97 (i), Optical systems &c.]. This subject-matter does not appear in the Specification as accepted.

Abstract: The invention relates to esters of 6-deoxyoxytetracycline having the formulae <FORM:1100885/C2/1> <FORM:1100885/C2/2> wherein A is -CH3 or YSCH2, Y being primary or secondary C1-C12 alkyl; R11CO (R11 being C1-C3 alkyl); phenyl; mono- or di-substituted phenyl; benzoyl; -CF3; or R1CH2 (R11 bein mono- or di-substituted C1-C6 alkyl, C1-C6 carbalkoxy, halo, phenyl, mono- or di-substituted phenyl, or furyl); each substitunte of mono- or di-substituted alkyl being C1-C6 alkoxy, C1-C6 carbalkoxy or halo, and when two substituents are on the same carbon, at least one is C1-C6 carbalkoxy; and each substituent of mono- or di-substituted phenyl being C1-C6 alkyl, alkoxy or carbalkoxy, or nitro; and wherein B is hydrogen; or wherein A with B is methylene; wherein R3 is alkanoyloxy, phenoxyalkanoyloxy or alkoxyalkanoyloxy, in which the alkanoyloxy groups are C2-C6; and wherein R2 and R4 are each hydroxyl, alkanoyloxy, phenoxyalkanoyloxy or alkoxyalkanoyloxy, in which the alkanoyloxy groups are C2-C6; and also to the O12a-phenoxyalkanoyloxy - and alkoxyalkanoyloxyderivatives of oxytetracycline, wherein the alkoxy group is C1-C6, and to the acid addition and metal salts of the said compounds.  The lower esters, i.e. the O12a-monoacyl and O5,O12a-diacyl compounds, may be prepared by esterifying the corresponding non-esterified tetracycline compound or the O5-acyl ester, whichever is appropriate, with at least one molar proportion of carboxylic anhydride or preferably carboxylic acid chloride, in an inert solvent such as acetone, tetrahydrofuran, methyl esters of ethylene glycol, diethylene glycol or preferably dioxane, at about 0 DEG  to 50 DEG C.  The ester is obtained by precipitating unesterified reactant as the hydrochloride, and adding the mother liquor to a large volume of non-solvent for the ester, e.g. hexane, when the required ester is precipitated.  The higher esters of the invention, i.e. the O10,O12a-di-acyl and O5,O10,O12a-tri-acyl esters, are prepared by esterifying the corresponding non-esterified or less-esterified tetracycline with 2-8 molar proportions of carboxylic anhydride in the presence of 2-8 molar proportions of pyridine, at 15 DEG -40 DEG C., if required in an inert solvent such as dimethylformamide. The aforesaid lower esters may alternatively be prepared by mild hydrolysis of the corresponding O10,O12aand O5,O10,O12a-esters, respectively, for example by treatment with aqueous ammonium hydroxide.  The products may be treated, in an inert solvent, with one equivalent of acid or metallic base to provide the corresponding salt, which may be recovered by evaporation of the solvent or by addition of a non-solvent.
