Title: Urea-antibiotic adducts and process for preparing the same
Inventor: MASSEY EDDIE HERMAN
IPC: A23K20/195
Filed: 1968-12-04
Abstract: 1,244,019. Macrolide-urea adducts. ELI LILLY & CO. 4 Dec., 1968 [4 Dec., 1967 (2); 15 July, 1968], No. 57629/68. Heading C2A. Novel aldehydic-rnacrolide bis-ureas wherein the aldehyde group of 1 molecule of an appropriate macrolide is combined with 2 molecules of a urea of formula wherein Am is -NH-R, R being phenyl, tolyl, halophenyl or trifluoromethylphenyl; or R<SP>1</SP> and R<SP>11</SP> being independently hydrogen, C 1  to C 4  alkyl or C 3  to C 4  alkenyl and the sum of their carbon atoms not exceeding 4, are prepared by reacting in a neutral solvent, at least 2 moles of the urea with 1 mole of the macrolide. The macrolides may be tylosin, macrosin, desmycosin, lactenocin, carbomycin, carbomycin B, niddamycin, spiramycins A, B, C and D or leucomycins A 1  to A 8 . Ureas may be urea or N-methyl-; N,N-diethyl-; N-n-butyl-; N- allyl-; N-phenyl-; N-(p-chlorophenyl)-; N-(otolyl)-; or N- (p .trifluoromethylphenyl)-urea. The compounds are preferably prepared by adding the macrolide or a salt thereof to a saturated aqueous or alcoholic solution of the urea at room temperature, allowing to stand, diluting with water and bringing to pH 9, and saturating the solution with sodium chloride to precipitate the required product. This is filtered off, dissolved in chloroform, the solution washed with water, and the chloroform evaporated off; the product is finally recrystallized, e.g. from aqueous acetone. Dihydro (ketone reduced) tylosin bis-urea is prepared by reducing tylosin bis-urea in ethanolic solution with sodium borohydride, and is subsequently hydrolysed by treatment with aqueous ethanol at pH 5À0 and 90‹ C. for ¢ hour to give the novel antibiotic dihydro- (ketone reduced) tylosin, this product being extracted from the reaction solution with methyl - ene dichloride at pH 5À0 to 5À5. Alternatively, the dihydro (ketone-reduced) bis-urea is hydrolysed to give the novel antibiotic dihydro/ketone-reduced) desmycosin by aqueous hydrolysis at either pH 2À8 and room temperature for 4 days or pH 3À6 and 100‹ C. for 1¢ hours, the said antibiotic being extracted from the hydrolysate with methylene dichloride at pH 7 to 8. Pharmaceutical compositions comprise one or both of the antibiotics dihydro(ketone-reduced) tylosin and dihydro(ketone-reduced) desmycosin together with a carrier. Veterinary compositions for administering to ruminants comprise an aldehydic-macrolide bis-urea as defined above together with a carrier which may be an animal feedstuff.

Title: Optical reproduction systems for high-resolution sonar or radar charts
IPC: G03H3/00
Filed: 1972-12-28
Abstract: 1405440 Optical apparatus SIEMENS AG 28 Dec 1972 [30 March 1972] 59837/72 Heading G2J In an optical reproduction system for sonar or radar charts, a series of unidimensional holograms I produced by a pulsed sonar or radar system and recorded as a function of the reception time is reconstructed by illuminating the holograms 1 by a convergent laser beam 2 and reproduced by means of a lens 4 having a short focal length F4 and arranged on the optical axis at a distance from the focus of the laser beam corresponding to its focal length. At the same time the range co-ordinate p is reproduced in magnified form by a cylindrical lens 3 and the lens 4 upon a cylindrical lens 6 arranged at an angle to the optical axis. The reconstruction plane 5 of the reduced azimuthal co-ordinate x is at an angle # relative to a plane perpendicular to the optical axis. By means of the cylindrical lens 6, which is at an angle of 90-0 degrees relative to the optical axis, the reconstruction plane of the azimuthal coordinate x is reproduced at infinity. The image planes of the azimuthal and range co-ordinates of the object are superimposed by means of a lens 7 and a cylindrical lens 9, the focal lengths of these lenses being so chosen that the magnifications of both co-ordinates are the same. By using the tilted cylindrical lens 6, the image magnification is made independent of the object range, and therefore it is possible in this fashion to produce undistorted sonar or radar charts 10.
Patent GB-599248-A (GB)
Abstract: 599,248. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. July 29, 1942, No. 10627. Convention date, April 30, 1941. [Class 97 (iii)] In' a directional gyroscope, two normallyequal air jets escaping from the vertical ring act differentially when the rotor case is displaced relative to the vertical ring and create a torque which restores their relative positions. As shown, the air exhausted through a pipe 4, Fig. 1, and drawn into the casing 1 through a filter 3, passes through openings 28, 29 to drive the rotor and thence passes through channels 30, 31 in the hollow trunnions of the rotor case 22. As shown in Figs. 3 and 4, the trunnions are partially cut away to constitute rotary valves leading to passages 32, 33, pipes 37, 38 and horizontally-directed outlets 34, 35 in the vertical ring 16. The air from the outlets enters a chamber 9 shielded from the sensitive parts of the gyroscope, and finally leaves through passages 40, 42. Normally (that is when the rotor axis is at right angles to the axis of the vertical ring), the torques exerted by the jets issuing from the outlets 34, 35 balance each other. If this condition is disturbed, the torques become unequal owing to the action of the rotary valves, and a precessional movement of the rotor case results so as to restore the balanced position. In a modification, the rotor is driven by air above atmospheric pressure. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 599,605. This subject-matter does not appear in the Specification as accepted.
