Abstract: A podium for a lubricating dispenser, the podium including an upright support structure, a housing attached to the support structure, a shelf attached to the support structure and extending over the housing, the shelf having mounting means thereon for receiving and retaining the lubricating dispenser, the shelf having a trough therein, the housing having a hole in an upper surface thereof, the hole being adapted for a hose to pass therethrough from the housing to the dispenser, the mounting means being adapted to receive the dispenser such that a grip portion of the dispenser extends outwardly from the support structure and the nozzle portion of the dispenser extends inwardly toward the support structure and over the trough.

Abstract: In an automatic chemical testing apparatus in which different chemical tests are performed selectively on one or more aliquots of each of a number of samples, samples are placed in successive ordinal positions for sequential aspiration into the apparatus for testing. Selection means in a selection panel are actuated to enable a position, i.e. to enable storage of instructions for tests to be performed on a sample in a particular ordinal position after it is aspirated into the apparatus. Test selection means are operated to program tests to be performed for the sample in the enabled position. Indicator means, e.g. lamps, are energized to indicate which position is enabled and which positions have been programmed. A further display indicates which tests have been programmed for an enabled channel.
