Certain 3-substituted-2,4(1H,3H)-di-oxo-quinazoline and 3substituted-2-thio-4-oxo(1H,3H)-quinazoline derivatives and pharmaceutically acceptable acid addition salts thereof having the formula
Abstract:
Transport swab tube apparatus is described capable of storing and transporting to a clinical laboratory a swab containing a microorganism sample and a suitable preservative medium. The apparatus comprises in combination an outer tube container having a removable sealing cap, a hollow tubular swab member having a bibulous swab material at one end and a liquid storage receptacle at its other end, and wherein the liquid storage receptacle and the swab member are supported by the removable sealing cap. When the cap is placed on and seals the tube container, the swab member is supported within the tube container so that the bibulous swab material does not touch the walls or end of the tube container. When desired, the liquid in the liquid storage receptacle can flow through the hollow swab member and contact the swab material.
Abstract:
Methods and apparatus for measuring and adjusting the concentration of a solution to a standard concentration or a multiple thereof are provided in accordance with the invention by detecting the concentration of a solution and producing an electrical signal representative of the detected concentration. The electrical signal produced is compared with a reference value and diluent is delivered to the solution at a rate governed by the magnitude of the difference between the electrical signal produced and the reference value until the concentration of the solution is adjusted to substantially the same concentration of a standard solution. A measurement of the concentration of the solution is indicated by an appropriately calibrated meter.
Abstract:
Meat emulsions, such as those suitable for the production of frankfurters and poultry or fish products, can be extended by the addition of an aqueous mixture of vegetable protein fiber, vegetable protein isolate, albumen, vegetable protein concentrate, edible whey, emulsifier, non-fat dried milk solids, gluten or an aqueous flour slurry, and salt. Appropriate amounts of seasoning, vitamins and minerals can also be present. The resulting extended emulsion mixture when cooked produces a final product which is equal to or superior to the prior art all-meat products.
Abstract:
Immunological reagents capable of direct agglutination with antigens are prepared by pre-polymerizing the antibody to form an aggregate and then coupling this aggregate to a microbial cell carrier particle with a chemical coupling agent. The prepolymerization of the antibody can be accomplished by the use of the same or another coupling agent. The use of the microbial cell carrier particle allows the reagents formed to be used as immunological indicator particles in slide tests which permit a quick read-out of test results. The reagent formed may be prepared and shipped in dry form and then reconstituted with liquid for use.
Abstract:
The disclosed derivatives of 1,3-disubstituted 2,4 (1H,3H)quinazolinediones produce vasodilation in experimental animals. The 1,3-disubstitutions include, among others, 1(alky(alkylamino))-, 1-(alkylpiperidyl)-, 3-(alkyl(alkylamino))-, 3-(alkyl(4-phenyl-1-piperidyl)-, and 3-(alkyl(4-phenyl-1piperazinyl))-moieties. In the latter two substituents the phenyl group optionally is substituted with halogeno or loweralkyl groups. Additionally, the compounds optionally are substituted at carbon atoms 5 through 8 of the quinazolinedione nucleus with halogeno, nitro, alkoxy, and alkylamido substituents.
Abstract:
A solid state electrode for use in determining ion concentration in an aqueous solution. The electrode comprises an electrically conductive inner element with a salt disposed on a surface portion thereof having as a cation a cation form of the element and also having an anion, a hydrophilic layer in intimate contact with the salt and including a water soluble salt of said anion and a hydrophobic layer in intimate contact with the hydrophilic layer whereby the hydrophilic layer is shielded from contact with the ion-containing aqueous solution. This electrode may function as a reference electrode as well as an electrode for identifying specific ions.
Abstract:
Certain substituted Beta -arylamidoacrylic acids and a method of preparing them are disclosed. These compounds are useful as antiinflammatory and diuretic agents.
