  • Patent number: 4489220
    Abstract: A test set designed for testing meter reading units as well as telephone line connections for automatic utility meter reading systems. The test set is capable of simulating the meter reading apparatus when testing the telephone line and of simulating the telephone line when testing the meter reading components. The test set further simulates the receiving apparatus in the central office to test the combination of the meter reading apparatus and the telephone line. The test set is self powered by batteries or may be powered from conventional AC outlets. The test set is operative both in the telephone plant and in the field.

  • Patent number: 4457052
    Abstract: An improved buckle for a child's safety car seat in which a release plate normally bears against a center plate, within an enclosing housing, to receive in locking relation hasp tips having opening cooperating with bosses on the release plate. The housing is configured to avoid cocking or blocking of the hasp tips on insertion, and to bias the housing covering the bail portion of the buckle against peeling away to expose the metal to the harness straps connecting the buckle to the child's car seat.

  • Patent number: 4454877
    Abstract: A nebulizer comprising of an elongated body including a nebulized fluid emission opening at one end with a nebulizer fluid reservoir communicating with the opening and a fluid barrier means adjacent to the opening. A wick extends between the reservoir and barrier for conveying nebulizer fluid to the barrier region from the reservoir. A source of pressurized gas is within a housing along with a means for conveying the pressurized gas to the wick in the region of the barrier. The conveying means includes a perforated section which extends into the region of the wick and through the barrier. The pressurized gas traverses the conducting means and aspirates the nebulizer fluid during passage through the barrier. The perforated section is a helical spring and the wick is a carpet-like fabric. A novel form of perforated barrier in the form of a closely spaced helical spring is enclosed. A novel filter formed from a knurled rod within a passage also is disclosed.
