Abstract: A printing caller ID device includes an audio recording device for recording incoming telephone messages and telephone numbers, and also includes a printer for printing telephone numbers received by a caller ID system associated with the device. The present device combines both of the above features in a single compact unit, suitable for desktop use or use in another area of limited space. The device includes controls for audio playback for listening to messages received, and also includes a touch screen system for operating the caller ID printer functions. The printer can be set to print all caller IDs received from initial actuation, or may be programmed to print caller IDs received during a preselected time period, as desired. The user of the present printing caller ID device is thus freed from having to listen to a series of audio messages to retrieve any desired information.

Abstract: A method for analyzing solid material in a liquid sample comprises the steps of: distributing the sample equally by passage through a number of discrete wells adapted to retain the solid material, the concentration of solid material being such that it is absent in at least one well; and analyzing the wells for the presence of retained solid material. A device adapted for use in a method for analyzing solid material in a liquid sample comprises the combination of: a container for the sample; a unit comprising a number of discrete wells adapted to retain the solid material and allow the passage of liquid under the application of reduced pressure; structure for drawing liquid from the container and through the wells under reduced pressure; and a manifold or other element that provides uniform distribution of the sample passing from the container into the wells.
