Abstract: A solid state electronic digital pressure gage which is responsive to the inlet pressure (P1) and the outlet pressure (P2) of a device undergoing a flow test to measure the pressure differential across the device at different flow rates. The pressure gage includes a housing, a face plate mounted on the housing, and a printed circuit board may be mounted on the back of the face plate on which various electronic circuitry, components and controls are mounted. Certain of the controls may be adjustable from the front of the face plate. A pair of solid state pressure transducers is mounted on the housing, and these transducers generate electric signals which are a function of the pressures applied to the transducers. The transducers are connected to an electronic signal difference determining circuit which is included in the electronic circuitry, and the difference determining circuit generates a signal representing the difference between the pressures applied to the two transducers.

Abstract: A stackable container for seasonings which comprises a hollow cylinder having an integral top wall and an integral bottom wall. An integral upwardly extending tubular mouth member of reduced diameter is formed on the top wall and centrally located on the top wall coaxial with the cylinder. The bottom wall has an upwardly extending centrally located circular well coaxial with the cylinder. The well has a selected diameter to receive the tubular mouth of a like container to enable the containers to be stacked over one another in a stable tier.
