  • Patent number: 4104366
    Abstract: Aqueous solutions of .sup.99 technetium salts wherein the .sup.99 technetium is in reduced valencey state, when administered to mammals, permit identification of the skeleton and of calcareous tumors by scintigraphy (radiographic scanning). The solutions are conveniently prepared by mixing one or more phosphonic acids (or their salts) with one or more reducing salts, and adding the mixture to an aqueous solution of a pharmaceutically acceptable .sup.99 pertechnetate salt. Reduction of the valence of the technetium occurs rapidly, and the resulting solution is adequately stable for use in scintigraphy.The phosphonic acid and reducing salt components can be premixed. Aqueous solutions of the premix are stable for long periods of time in the absence of free oxygen and the premix is stable to air so long as it is dry.

  • Patent number: 4086334
    Abstract: The water-soluble calcitonins and the water-soluble pharmaceutically-acceptable compounds of acidic nature which are effective against Paget's disease and which contain at least two acidic groups separated by not more than two carbon atoms act synergistically in inhibiting a pathological increased calcium metabolism rate (including the solubilization of bone calcium which occurs in Paget's disease). The components in combination, when administered in respectively preferred amounts, inhibit or arrest loss of calcium by the bones of the body with less severe side effects than those caused by equivalent therapeutic doses of the calcitonin alone or by equivalent therapeutic doses of the compounds of acidic nature alone.

  • Patent number: 4082112
    Abstract: A hose coupling wherein the ends of two hoses are connected to tubular valve bodies having axially extending passages with annular valve seats which face the respective hoses and are normally engaged by disk-shaped elastic valve elements under the action of helical valve springs. A tubular member is reciprocably installed in one valve body at the open end of the respective passage and has a centrally located collar which is flanked by elastic sealing rings. When the two bodies are coupled to each other by a bayonet lock, one end of the tubular member lifts the valve element in the other body off the respective seat and the other end of the tubular member then lifts the valve element in the one body off the respective seat under the action of the valve spring in the other body. When the two bodies are disconnected from each other, the valve spring in the one body engages the respective valve element with the adjacent seat and shifts the tubular member with respect to the one body.

  • Patent number: 4075119
    Abstract: The invention relates to statistical mixtures of halogenated bisphenols with halogen-free bisphenols and to processes for their preparation. This invention further relates to new aromatic, bromine-containing and/or chlorine-containing, high-molecular weight thermoplastic polycarbonates with good resistance to fire (oxygen index .gtoreq. 36%) and good flow properties, to their preparation from the statistical mixtures of halogenated bisphenols and halogen-free bisphenols and to their use alone or as a mixture with halogen-free polycarbonates or with thermoplastic polyesters for the preparation of moldings, films and fibers.

  • Patent number: 4074133
    Abstract: An ionography imaging chamber for use in X-ray systems wherein dielectric receptor sheets are introduced into an interelectrode gap of the imaging chamber and the gap is filled with compressed high Z gas during imaging of an object onto a sheet in the chamber so that the sheet is provided with a latent image of the object. The chamber has a gate defining an arcuate channel for introduction of receptor sheets into and evacuation of sheets from the interelectrode gap. In order to prevent escape of high Z gas into the atmosphere and/or penetration of air into the gap, the gate has one or more orifices for admission of a compressed buffer gas (for example, CO.sub.2 gas) which is readily separable from the high Z gas whereby the buffer gas flows toward and away from the gap and mixes with high Z gas which tends to escape from the gap by way of the channel.

  • Patent number: 4034086
    Abstract: Pyrrolidone-5,5-diphosphonic acids having the formula ##STR1## wherein R is a member selected from the group consisting of hydrogen and alkyl having from 1 to 6 carbon atoms; as well as their water-soluble salts. The pyrrolidone-5,5-diphosphonic acids are excellent sequestering agents especially for alkaline earth metal ions. They are stabilizers for percompounds and are useful in the delaying of the setting times for gypsum. In addition, the compounds are useful as cosmetic preparations such as toothpastes and mouthwashes where they prevent formation of tartar and plaque and are useful in therapy in the treatment of diseases related to the abnormal deposition or dissolution of difficultly soluble calcium salts in the animal body.
