Title: Antibiotic preparations and process for obtaining the same
Filed: 1947-08-19
Abstract: Clear aqueous solutions of tyrothricin, which are physically and bactericidally stable and are useful for medicinal and veterinary purposes (see Group VI), are manufactured by mixing an aqueous or alcoholic solution of a solubilizer, comprising a water-soluble salt of an organic quaternary ammonium compound having three alkyl groups of not more than 2 carbon atoms and one straight chain alkyl group of 12-18 carbon atoms attached directly to the nitrogen atom, with an alcoholic solution of tyrothricin, and, if necessary, diluting the resulting solution with water.  The amount of solubilizer depends on the concentration of tyrothricin in the final solution, and varies between about 0.02-1.5 per cent.  Examples describe the use as solubilizers of cetyltrimethylammonium acetate, chloride and bromide, n-dodecyltriethylammonium propionate, n-tetradecyldimethylethylammonium acetate and n-octadecyltrimethylammonium chloride.ALSO:Clear aqueous solutions of tyrothricin, which are physically and bactericidally stable and are useful for medicinal and veterinary purposes, are manufactured by mixing an aqueous or alcoholic solution of a solubilizer, comprising a water-soluble salt of an organic quaternary ammonium compound having three alkyl groups of not more than two carbon atoms and one straight chain alkyl group of 12-18 carbon atoms attached directly to the nitrogen atom, with an alcoholic solution of tyrothricin, and, if necessary, diluting the resulting solution with water.  If desired there may be added an aqueous solution of a water-soluble salt of a vasoconstrictor, e.g., ephedrine, neosynephrin or the substances sold under the Registered Trade Marks "Epinephrim" and "Benzedrine."  In examples: (1) an aqueous solution of cetyltrimethylammonium acetate is added to an alcoholic solution of tyrothricin and the mixture is diluted with water; the product is suitable for treating bovine mastitis by injection into the udder; (2) stronger solutions are employed, giving a product suitable for topical application to wounds, ulcers and abscesses, and for treatment of osteomyelitis and infections of the pleural cavity, nasal sinus and eye; (3) an alcoholic solution of tyrothricin is added to an alcoholic solution of cetyltrimethylammonium acetate, the mixture is added to an aqueous solution of ephedrine lactate containing sufficient dextrose to make the final preparation isotonic, and the solution is diluted with water; the product is useful as an inhalant for treating congested or infected nasal sinuses; (4) the solubilizer in (3) is replaced by the corresponding chloride and the proportions varied; (5) an alcoholic solution of cetyltrimethylammonium bromide is diluted with water and added to an alcoholic solution of tyrothricin and the product is further diluted; (6) an aqueous solution of n-dodecyltriethylammonium propionate is added to an alcoholic solution of tyrothricin and the mixture diluted; (7) the solubilizer in (6) is replaced by n-tetradecyldimethylethylammonium acetate, and (8) by n-octadecyltrimethylammonium chloride.

The elements are arranged so that movement of the regulator in either direction about an axis -X, X, or - Y, Y through an angle greater than α causes one or more bores 30, 31, 32, 33 to be closed and a pneumatic signal to be supplied to a hydraulic cylinder which corrects the deviation. Each sensing element rests on an eccentric pivot 27 and has a stub 2a, 2b of ptfe to co-operate with the bores. The bores may be replaced by pressure plugs.

Title: Improvements in or relating to balanceable electric measuring networks
IPC: G01F1/37
Filed: 1953-08-21
Abstract: 734,999. Resistance networks. BRISTOL CO. Aug. 21, 1953 [Sept. 8, 1952], No. 23161/53. Class 37. [Also in Group XXXVIII] In a potentiometer-type self-balancing and non-linear measuring system a phase-sensitive detector whose output drives the balancing servo motor is in a closed circuit loop with the system transducer and the impedance of this loop is variable and has a higher value than the associated tapped potentiometer to ensure uniform measurement sensitivity. In Fig. 2 an A.C. transformer-type transducer 26 controlled by fluid flow in a conduit 20 delivers a quadraticlaw variable voltage into amplifier-phase sensitive detector 36 to drive a servomotor 38 until the voltage output of A.C. potentiometer network 10, 15 balances the transducer 26 voltage and pointer 40 co-operates with scale 41 to indicate prevailing fluid flow rate in the conduit 20. In the potentiometer network 10, 15 tappings 11, 16 are ganged so that A.C. fed to potentiometer 10 varies simultaneously with the voltage tapped from potentiometer 15 whereby the latter as the network output varies with the square of the displacement of the pointer-slider assembly 17 and pointer 40 therefore moves along a linear scale 41. The closed circuit loop, Fig. 3, across the tapped part of potentiometer 15 comprises detector 36 and transducer 26 and measurement sensitivity is the ratio of change in loop current I to given increment in displacement of pointer-slider assembly 17. In Fig. 3 DRs is the variable impedance tapped from potentiometer 15 and Zg + Zt the closed circuit impedance and the Specification develops mathematically and demonstrates with the aid of characteristic curves, Fig. 4 (not shown) that sensitivity is less variable when Zg + Zt is always less than DRs. Accordingly the invention provides Fig. 5 wherein the circuit loop is of the required low impedance (e.g. Zg + Zt/DRs = <1>/10) and includes a series rheostat 49 variable with the gang-assembly 17 so that as DRs varies Zg + Zt varies to maintain the desired ratio. Potentiometer 10 is also associated with a variable resistor 46 but this is done to avoid the use of a flexible lead. The transducer 26 controlled by differential manometer 22 comprises opposed secondaries so that output is directly proportional to the pressure differential.

Filed: 1929-07-31
Abstract: 337,417. Major, H. V., and Jones & Co., Ltd., S. July 31, 1929. Feeding webs.-In a sealing-machine in which an adhesive-coated tape is drawn from a roll past a moistening device, the roll or rolls of tape rest upon a pivoted flap and the trip passes over a roller, carried by the flap, prior to passing beneath the flap to a damping appliance. When the roll is large, it rests partly on the flap and partly on the roller, but when it is small it rests wholly on the flap to avoid lessening its resistance to rotation. The machine comprises a bent bottom plate 6 and an upper bent plate or flap 3 pivoted at one end 4 and supported at its free end on the plate 6 by lugs 5 which permit coaxial rollers 2 at that end to rotate freely. Large rolls of adhesive tape rest upon the rollers 2 and upon the plate 3 at 3<a>, but as the roll is reduced in size, it comes to rest upon the surfaces 3<a>, 3<b> of the plate 3 only. The tape withdrawn passes around the rolls 2 and between the bent plates 3, 6 which tend to give it a curvature reverse to the curvature of the roll. Finally the tape passes over parallel rollers 10 above a moistening bath 14 and between plates 11, 12 to a brush 13, the length withdrawn being severed against a serrated edge on the plate 11. Withdrawal of the next piece is started by pressing forwards the strip above the rollers 10. Several rolls of different widths may be placed side by side in the machine, pivoted side plates 17 adjustably mounted on a rod 19 separating the rolls from one another.

Title: Improvements in or relating to superheterodyne receivers
IPC: H03J3/28
Filed: 1931-08-20
Abstract: 375,129. Wireless receiving systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Aug. 20, 1931, No. 23497. Convention date, Aug. 20, 1930. [Class 40 (v).] The intermediate frequency in a superheterodyne receiver lies within 0À7 of the lowest and 1.4 of the highest frequency on the desired frequency band. By this means the image frequency is widely separated from the received frequency, thus rendering high selectivity unnecessary. Where two wave bands are to be received, the intermediate frequency may be between the two bands. To facilitate ganging of the heterodyne and receiving circuits the local oscillator is tuned by a fixed condenser and small variable condenser having specially shaped vanes so that it may be unicontrolled with the receiver tuning condenser. If operation on several frequency bands is desired, a separate small variable heterodyne condenser is provided for each band. The receiver has preselection means preceding the heterodyne stage.
