Abstract: Rapid identification of different species of microorganism selected from fungi and yeast like algae is accomplished by culturing the microorganism for several hours under normal conditions on a non-inhibitory mycological medium which stimulates the microorganism to make characteristic enzymes by which the microorganism can be identified, distributing the culture (in suspension) onto several supports containing different substrates which are capable of reacting with the enzymes so produced by the different species of microorganisms; and rapidly incubating the admixture to produce a distinctly colored or colorable reaction product.

Abstract: Enteric coated aspirin tablets rendered shock-insensitive by the provision of a protective coat of hydroxyproply methylcellulose of at least about 1.5% by weight based on the weight of the tablet core.
Abstract: A two part mastitis cannula cap includes an outer cap and an inner cap. The inner cap is not as long as the cannula so that a free end of the cannula protrudes beyond an end face of the inner cap. This cannula protrusion is covered by the outer cap which is securable about the free end of the inner cap. Controlled depth partial insertion of the cannula into the teat canal of a dairy cow can be accomplished by removal of only the outer cap. Alternatively, full depth cannula insertion is accomplishable upon removal of the two parts of the cap.
Abstract: An efficacious parenterally administered modified live Canine Corona virus vaccine which provides systemic, humoral protection and also protection of the intestinal tract in dogs from infection by virulent Canine Corona virus is produced. A method for propagation of the Canine Corona virus and its attenuation and a method of evaluating the effectiveness of a Canine Corona virus vaccine in canines is also disclosed.

Abstract: An improved microbiological test tray is described which are provided with fasteners so that two or more of the trays may be joined together for ease in inoculation, incubation, lyophilization and reading. In another aspect of the invention an improved tray structure is described which provides openings for the flow of vapor during the lyophilization step so that a greater number of trays may be lyophilized at the same time and also that lyophilization may be carried out in a shorter period of time due to the improved vapor flow. In another aspect of the invention an improved test card is described in which the API 20 test strip is reshaped into a card of two rows of ten cupules conforming to the same pattern as other frequently used test trays. A holder tray is provided for the card and the holder is provided with connecting fasteners so that it and the test card may be joined into one or more additional test trays for ease in inoculation, incubation and reading.

Abstract: An aqueous antacid composition of magaldrate gel and a process for preparing same are described by the invention. The composition is prepared from and contains precipitated and undried magaldrate gel and a fluidizing of a first and second fluidizer. On fluidizer is provided by an aluminum hydroxide gel having colloidal properties and the second by a pharmaceutically acceptable citrate ion source including citric acid. The process and composition are characterized in providing a fluid, resuspendible, pharmaceutically elegant suspension possessing high antacid capacity and stability at even elevated magaldrate concentrations in addition to the ability to fluidize stiff, paste-like magaldrate gel cakes.
Abstract: An rehydratable antacid composition of magaldrate gel and a process for preparing same are described by the invention. The composition is prepared from and contains precipitated and undried magaldrate gel, a polyhydric alcohol and fluidizing amounts of a first and second fluidizer. One fluidizer is provided by an aluminum hydroxide gel having colloidal properties and the second by a pharmaceutically acceptable citrate ion source including citric acid. The process and composition are characterized in providing rehydratable antacid composition which when admixed with water forms a fluid, resuspendible, pharmaceutically elegant suspension possessing high antacid capacity and stability at even elevated magaldrate concentrations in addition to the ability to fluidize stiff, paste-like magaldrate gel cakes.

Abstract: Apparatus is provided for evacuating and compacting filled aerosol cans. The cans are manually placed into a feed chute and sensing means are provided to confirm proper can orientation and to permit gravity feed of the can into a crushing mechanism. A hydraulic ram pushes the can against a stator plate. A punch reciprocates through an opening in the stator plate puncturing the bottom of the can so that the contents discharge into a receiver where the liquid contents are separated from the propellent and recovered. An air logic means controls the sequencing of the operative steps. The apparatus can be used in an explosive area.
