Abstract: 1,136,347. Recovery of basic antibiotics. CHAS. PFIZER & CO. Inc. 8 Feb., 1967, No. 6119/67. Heading C2A. [Also in Division B1] The adsorption of a basic antibiotic upon a particulate carboxylic acid type cation-exchange resin is obtained by flowing an impure solution of said antibiotic, e.g. whole or clarified fermentation broth, in a substantially horizontal direction through a free suspension of said resin until the adsorption of the antibiotic content of said solution by said resin substantially ceases and then separating the antibiotic-depleted solution from the resin adsorbate, said resin being present in a proportion of about 0À1 to about 0À8 volume per volume of solution in the vessel confining said resin. The resin should have a particle size of about 100 mesh or coarser (U.S. Standard Sieve) and a specific gravity of about 1À0. Preferably, the resin is used in the form of a salt with a monovalent cation, e.g. sodium or ammonium salt. Copolymers of acrylic acid or methacrylic acid with about 2 to 8 per cent of divinylbenzene are preferred resins. Specified antibiotics are streptomycin. neomycin, viomycin, polymycin, dihydrostreptomycin, hydroxystreptomycin, streptothricin and mannosidostreptomycin. For streptomycin, the pH of the broth is adjusted to pH 7 to 8. The adsorption is preferably carried out in two or more troughs 12 connected in series and each fitted with a concentric shaft 20 carrying a plurality of vanes 24 one of which carries a rubber wiper 26 for preventing agglomeration of the resin in the lower part of the trough. The flow of antibiotic is such that the effluent from the last vessel is substantially free of antibiotic content. After washing with water, the antibiotic - saturated resin is eluted with 2N.H 2 SO 4 , neutralized and the streptomycin recovered therefrom. Alternatively, rotating drum apparatus may be used. The resin may be maintained in the suspended state by mechanical, ultrasonic or gas bubble means.

Title: An improved apparatus for converting the magnitude of a measurement into a frequency proportional thereto
IPC: G08C19/16
Filed: 1941-05-22
Abstract: 548,742. Electric measuring. TRIGGS, W. W. (Akt.-Ges. Brown, Boveri, & Cie). May 22, 1941, No. 6587. [Class 40 (i)] The quantity to be measured controls the speed of a constantly rotating disc having holes &c. in its periphery which is arranged in the neighbourhood of an inductive or capacitive element of a circuit carrying high-frequency oscillations These oscillations which are thus modulated by a frequency which depends on the speed of the disc and therefor on the quantity to be measured are then rectified and used to indicate the measurement. In arrangements illustrated by Figs. 1 and 3 (not shown) a single valve acts as oscillation generator and rectifier. In a modification, Fig. 4, the modulated oscillations are produced by causing the disc 1 to vary the coupling between a separate oscillator 34 and a rectifier 6. In this case, a supplementary manually adjustable coupling 36 is provided to enable the most sensitive condition to be selected. Errors due to axial movements are avoided by arranging the disc between two coils. Errors due to eccentricity of the disc may be avoided by arranging two coils at the ends of a diameter. The disc may be of perforated magnetic or other metal or of insulating material with the holes filled with magnetic material. A material containing magnetic dust may be used for the cores of the inductors and for filling the holes in the disc. To avoid any braking effect on the disc, the valve anode may be fed through separate chokes instead of through the coils in the oscillating circuit.
