Abstract: An embodiment of a storage device for medical products includes a cabinet defining an enclosure having a plurality of compartments. In addition, the storage device includes a plurality of storage containers, each storage container configured to be inserted into a corresponding one of the plurality of compartments. Further, the storage device includes an actuation assembly including a plurality of arms that are configured to engage the plurality of storage containers so as to secure the plurality of storage containers in the plurality of compartments. Still further, the storage device includes a release mechanism that is configured to simultaneously actuate each of the plurality of arms to release the plurality of storage containers from the plurality of compartments.

Abstract: A clamp for an Erlenmeyer flask or other laboratory containers or racks uses nickel-coated, rare earth magnets to secure the clamp to a platform for a laboratory shaker. The base of the clamp has downwardly extending positioning bosses that seat in holes or indentations on the shaker platform to prevent horizontal sliding of the clamp when the shaker is in use. A removable and replaceable, elastomeric cover for the base of the flask clamp provides cushioning and prevents spinning of the flask when the shaker is in use.

Abstract: A method of determining liquid absorption of an aggregate comprises providing a shaker apparatus, a vacuum source and a container; placing a sample of the aggregate in the container; adding liquid to the container sufficient to reach a calibration mark on the container; weighing the sample and liquid; mounting the container to the shaker apparatus; connecting the vacuum source to the container; agitating the sample and liquid with the shaker apparatus; applying a vacuum to the sample and liquid with the vacuum source; after the agitation and vacuum steps, adding liquid to the container sufficient to again reach the calibration mark on the container; again weighing the sample and liquid; and subtracting the initial weight of the sample and liquid from the final weight of the sample and liquid in order to determine the liquid absorption of the aggregate.

Abstract: A hotplate with a stainless steel top plate to support a vessel. The stainless steel top plate has an upper surface with a substantially centrally located depression having a depth and area generally sufficient to absorb upward crowning of the top plate when heated. A heating unit is in a heat transfer relation with the stainless steel top plate, and a base unit is connected to the heating plate assembly; however, the base unit is not fastened directly to the stainless steel top plate, so that the stainless steel top plate can expand more uniformly when heated.

Abstract: A method of determining liquid absorption of an aggregate comprises providing a sample of the aggregate, adding liquid to the sample, subjecting the sample to a light source signal, monitoring a light reflected signal reflected from the sample and controlling addition of liquid to the sample as a function of the light reflected signal. The apparatus comprises a support for supporting a sample of the aggregate, a liquid source for adding liquid to the sample, a light source which subjects the sample to a light source signal, a light sensor which senses a reflected light signal reflected from the sample and a processor/controller which controls addition of liquid from the liquid source as a function of the reflected light signal. The light source is preferably an infrared source and the light sensor is preferably an infrared detector.

Abstract: An electrically operated device and fastener assembly for establishing an electrical and mechanical connection on the device. The fastener assembly generally includes a fastener and a washer which may be permanently flattened against the device to establish an electrical connection to a piece of coated metal. Upon removal of the fastener, the washer remains permanently flattened against the device or piece of metal and mechanically connected thereto by a build-up of coating material on projections associated with the washer. Fastener assemblies may be constructed using, for example, sheet metal screws requiring only one of the washers in the assembly or machine screws which may require two of the washers.
