    摘要： 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.

    摘要： An illumination device (10) for a phonograph record (18) has a housing (14) and bolts (22) for attaching the housing (14) to a phonograph tone arm (12). A battery (26) in the housing (14) and a contact switch (32) on the housing are connected to activate a timing circuit (28) for supplying current from the battery (26) to a light emitting diode (30). The light emitting diode (30) is positioned to illuminate an area around point (36) that stylus (20) contacts the record for a predetermined of time after the contact switch (32) is closed.

    摘要： 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.
