Abstract:
A test system for the semi-automatic analysis of chemical constituents in a test fluid which comprises test devices having test reagents and code means associated therewith and an instrument which receives the test devices and is programmed by the device code means for automatically reading the particular test reagents associated with the particular test device being used. Preferably the test reagents are in a dry form, immobilized in or on a carrier member which upon contact with the test fluid can be manually presented to the instrument. Another preferable embodiment of the present device comprises the use of the code means to calibrate the instrument each time a test device is introduced thereto.
Abstract:
3-substituted-5,5-diphenylhydantoin derivatives in which the 5,5-diphenylhydantoin moiety is attached at C3 by a loweralkylene bridge to a 4-phenyl-1-piperidyl, 4-hydroxy-4-phenyl-1-piperidyl, 4-phenyl-1,2,3,6-tetrahydropyridyl, 4-phenyl-1-piperazinyl, or loweralkylamino group are useful in the treatment of cardiac arrhythmias in mammals. One or both of the 5,5-diphenyl substituents optionally can be substituted in the ortho-, meta-, or para-positions with halogeno, loweralkyl, loweralkoxy, amino or nitro groups.
Abstract:
An improved test device for assaying a liquid specimen for microorganisms. The device is adapted to be inoculated by immersion in the specimen and to thereafter culture microorganisms therein by incubation in a sealable container. The device generally includes an absorbent matrix impregnated with a nutrient medium containing test reagents and a culture-fixing agent for localizing colony locations throughout the culturing period.
Abstract:
Administration of pharmaceutically acceptable 1-methyl-3-keto-4phenylquinuclidinium salts is described as a chemotherapeutic method of treating hypertension in hypertensives. Daily doses ranging from 10 mg/kg to 300 mg/kg are effective in producing an antihypertensive effect in the latter.
Abstract:
Process and apparatus are described for washing a tow of continuous filaments, such as protein fibers, wherein the tow and a treating liquid, such as an alkaline solution or water, are concurrently passed longitudinally along a conduit and several fluid streams, such as air streams, are passed transversely through the tow to agitate the filaments and enable the treating liquid to contact all the filaments.
Abstract:
1. A PROCESS FOR DETRRMINING THE CONSISTENCY AND QUALITY OF MICROBIOLOGICAL GROWTH SUPPORTING MEDIA, WHICH COMPRISES CONTACTING SAID MEDIUM WITH A COMPOSITION COMPRISING A PREDETERMINED QUALITY OF A MICROORGANISM CANABLE OF PRODUCING COLONIES IN OR ON SAID MEDIUM, SAID PREDETERMINED QUANTITY BEING AT LEAST THE MINIMUM INOCULUM REQUIRED TO PRODUCE OBSERVABLE COLONY FORMATION UNDER PREDETEMINED CONDITIONS OF INCUBATION, AND A MICROBIOLOGICALLY INERT COLLOIDAL SUSPENDING AGENT, INCUBATING SAID MEDIUM AND SAID COMPOSITION UNDER PREDETERMINED CONDITIONS AND OBSERVING THE NUMBER OF MICROBIOLOGICAL COLONIES THUS PRODUCED.
Abstract:
THE INVENTION PROVIDES A METHOD OF ALLEVIATING INFLAMMATION, EDEMA AND/OR PAIN IN A MAMMAL BY ADMINISTERING TO SAID MAMMAL BY THE TOPICAL ROUTE GALLIC ACID OR AN ALKYL ESTER OF GALLIC ACID, THE ALKYL MOIETY OF SAID ESTER HAVING 1 TO 8 CARBON ATOMS.
Abstract:
AN EGG EXTENDER COMPOSITION WHICH CAN BE ADDED TO EGGS FOR USE IN BAKING COMPRISES THE INTERRUPTED AQUEOUS GEL PRODUCT CONTAINING KAPPA CARRAGEENAN, XANTHAN GUM, LOCUSRT GUM AND POTASSIUM SALT. THIS PRODUCT CAN BE PRODUCED BY RAPIDLY COOLING WITH AGITATION THROUGH A TEMPERATURE RANGE AT WHICH GELATION WILL TAKE PLACE AN AQUEOUS MIXTURE OF THE ABOVE CONSTITUENTS.
Abstract:
ADMINISTRATION OF AN EFFECTIVE AMOUNT OF 1-(2-PYRIDYL) PIPERAZINE OR A NONTOXIC ACID ADDITION SALT THEREOF CONTROLS TREMOR SYMPTOMATIC OR PARKINSONISM IN MAMMALS. DAILY DOES RANGING FROM 10 MG./KG. TO 90 MG./KG. ARE CONSIDERED EFFECTIVE.
Abstract:
CITROYLFORMIC ACID, USEFUL AS A SEQUESTRANT AND AS A NEW MATERIAL FOR THE PRODUCTION OF CITRIC ACID, CAN BE PRODUCED BY THE BIMOLECULAR DECARBOXYLATIVE SELF-CONDENSATION OF OXALOACETIC ACID.
