  • Patent number: 6696962
    Abstract: Acoustic level sensing by creating, or failing to create, resonance in a tube having a free end. An acoustic transducer at one end of the tube injects sound at a frequency that could produce resonance, depending on whether the free end is open or closed. The drive to the acoustic transducer is then removed, and the sound decay in the tube is monitored to determine if resonance occurred. Based on that determination, a signal is produced that indicates whether a material has or has not closed the free end of the tube. Beneficially, the same acoustic transducer that produces the sound monitors the sound decay. To determine whether resonance has occurred, or to verify system operation, the sound decay at the possible resonant frequency can be compared to the decay at another frequency. Temperature compensation can be performed by attempting to produce resonance at a plurality of frequencies.

  • Patent number: 6066252
    Abstract: An alarm mechanism for use in chlorinators using chlorine tablets. The alarm mechanism signals when the chlorine tablets have dissolved to a pre-determined quantity and are in need of replenishment. The alarm mechanism has a low tablet register mechanism and an indicator. The low tablet register mechanism registers when the chlorine tablets dissolve to the pre-determined quantity, and preferably includes a counterweight mechanism calibrated and constructed so that it is activated when the chlorine tablets dissolve to the pre-determined quantity. The indicator indicates when the low tablet register mechanism registers that the chlorine tablets have dissolved to the pre-determined quantity. Preferably, the indicator includes a sensor and an alarm. The sensor senses when the register mechanism registers the dissolution of the chlorine tablets to the pre-determined quantity. The alarm, such as a horn or a light, signals the activation of the sensor.

  • Patent number: 5861805
    Abstract: Method and apparatus for effecting continuous automated querying of collection receptacles from a passing motor vehicle to ascertain whether articles have been deposited in each collection receptacle. Each collection receptacle has a detector capable of detecting whether at least one article has been placed within the collection receptacle, and a radio frequency transceiver. A motor vehicle provided for the purpose of collecting articles from the collection receptacles also has a transceiver. The transceiver of the motor vehicle continuously transmits a querying signal which is recognizable by the transceiver of each collection receptacle. When the detector has detected an article and a querying signal is received, the collection receptacle transmits an encoded response signal. This response signal is recognized by the transceiver of the motor vehicle, the identity of the transmitting collection receptacle is determined, and the results are annunciated to the operator of the motor vehicle.

  • Patent number: 5244020
    Abstract: A dispenser of foodstuff is particularly well adapted to deliver cheese for pizza making. A refrigerator contains a bin which may be completely removed from said refrigerator for cleaning, as in a dishwasher, for example. The bin features inwardly sloping walls so that the cheese does not normally stick to the wall. An auger delivers the cheese to a spout where a star wheel meters flow and breaks up any clumps in the cheese. A spring biased trap door closes the spout, especially when the bin is removed from the refrigerator. The refrigerator contains parts which control the opening and closing of the trap door and the turning of the auger. The entire system operates under the control of a programmable microprocessor which includes means for detecting when the bin is empty or is failing to delivery the cheese.

  • Patent number: 5003489
    Abstract: A totalizer apparatus, used with belt scales and other flow rate measuring devices producing output signals subject to zero drift, maintains an auxiliary totalizer register during zeroing operations so that should zero flow conditions be interrupted during such an operation, a correct total can still be maintained. This enables autozeroing operations to be implemented, for which purpose a further auxiliary totalizer is used to test for an extended absence of flow before permitting initiation of an autozeroing operation. If a zeroing operation results in an apparently excessive zero correction, it is rejected and assumed that flow has restarted during the operation; the first auxiliary totalizer register is used to update a primary register.
