Abstract: A hand-held pulverizer has a grinding section and a flat, detachable collecting plate into which pulverized material falls as it is ground. The pulverized material may be transferred from the collecting plate to a relatively small jar by attaching the broad end of a funnel-like device to the collecting plate, attaching a relatively small jar to the narrow end of the funnel, and inverting the funnel. When all of the material is transferred to the jar, the funnel may be removed, and a cap attached to the jar.

Abstract: An adapter closure for a container including a body portion, an axial passage extending through the body portion, an inwardly extending shoulder portion disposed along the length of the body portion intermediate the ends thereof, a first internally threaded section extending from one end of the body portion toward and terminating closely adjacent to the shoulder portion, and a second internally threaded section extending from the opposite end of the body portion toward and terminating closely adjacent to the shoulder portion.

Abstract: A device for the detection of microorganisms in a fluid sample comprising a first container a liquid nutrient medium and a second container containing one or more solid nutrient media, said containers being detachably connected so that the media can be brought into contact, is disclosed. Also disclosed is a method of detecting microorganisms in a fluid sample comprising introducing a sample of the fluid to be tested into a first container containing a liquid medium and incubating if desired; connecting said first container to a second container containing one or more solid media so that said media can be brought into contact; bringing the liquid and solid media into contact; incubating and determining the growth of microorganisms on the surface of the solid media.

Abstract: Ketchup rapping apparatus having a pair of L-form racks hinged to one another, each adapted to hold a ketchup bottle in a stationary seated position, one of the racks being pivotable through 180 degrees from a back-to-back relationship with the other rack to carry its bottle to inverted vertical alignment with the other bottle, a resilient guide cup to be disposed between the mouth ends of the aligned bottles for avoiding glass-to-glass bottle contact and for guiding the bottle being inverted down into the aligned position with the other bottle, a latch for securing the pivoted rack in the inverted position to allow easy porting of the apparatus in the inverted condition, and shock absorbing pads on the bottom of the non-inverted rack enabling rapping of the latter in the inverted condition of the apparatus against a solid surface so as to jar free a clogged ketchup flow condition without damaging the apparatus or the bottles.

Abstract: A device for dispensing fluid substances which includes a dispensing container for holding a metered amount of the fluid substance therein immediately prior to dispensing and which includes a primary opening in the top edge thereof which is adapted to be capped during filling of the dispensing container and which is adapted to be opened when it is desired that the metered amount of fluid substance should be dispensed from the container, the dispensing container also includes a secondary opening in the lower section thereof which may be substantially smaller than the primary opening, the device further includes a hollow adapter secured to the secondary opening of the dispensing chamber and adapted to be secured to the neck of a bottle or other source of the fluid substance to be dispensed, the hollow adapter including a dispensing collar adapted to be secured to the secondary opening of the dispensing container and a holder collar adapted to be secured to the neck of a bottle or holder of the fluid substance a
