Title: Wick-based liquid emanation system with child-resistant overcap
Inventor: WEFLER MARK E
IPC: A01M1/20
Filed: 1997-06-26
Granted: 2001-10-30
Abstract: A child-resistant, wick-based liquid emanation system includes a container (30) which is capable of containing liquid and has an opening (36). A wick (50) is partially disposed within the container (30) and extends through the  opening (36). A hollow overcap (101) encases the extended portion of the wic k and has a closed, separable tip (100) and an open base (200) attached to cov er the opening. The system is activated by separating the tip from the overcap.  A retainer may be provided for obstructing complete removal of the wick from t he container through the overcap after the tip is separated from the overcap. T he retainer can include a shoulder (300) disposed in the overcap (101) between the tip (100) and the base (200) to retain the wick (50) toward the base of the overcap. Alternatively, a protrusion (53) from the wick can engage an inner surface (225) of the overcap or the container. In this case, the overc ap can have a frangible portion facilitating separation of the tip, and the wic k can extend past the frangible portion toward the tip.

Abstract: Fumigation  of  grain  in  a  storage  facility  having  a plurality of grain silos (13) is effected from a single source (10) of a gaseous fumigant.  The single source of gaseous fumigant is connected to a gas supply duct (11), to which gas inlet ports of the silos are also connected.  The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop  across  the  orifice  plate  into  the  silo  is substantially greater than the pressure drop across any other component between the gas source and the silo.  With this arrangement, the flow rate of gaseous fumigant through the grain-containing silos in the facility suffers only a minor perturbation when a valve between the duct and a silo is opened or closed.   This minor perturbation can be readily compensated by maintaining the gas pressure in the duct at a constant value.

Abstract: A vehicle assembly system automatically decks and automatically fastens body components to chassis components. The system uses an automatic decking and fastening unit that includes a base with an elevatable platform repositionable relative to the base by at least one actuator.      A slidable unit carries a fastener driver, is supported on the elevatable platform, and is repositionable relative to the elevatable platform by at least one other actuator. The slidable unit also carries an arm that is repositionable relative to the slidable unit by yet another actuator. A pair of conveyors are positioned away from the base, are movable relative to the base and carry a pair of vehicle components. The conveyors are cycled so that the vehicle components are positioned relative to one another in a predetermined position, and the actuators are operated to reposition the fastener driver to a position determined by engagement of the slidable unit with one of the vehicle components.

Abstract: A dielectrokinesis detector includes a chamber housing an exact dielectric replicate reference material that is subjected to external static electrification. The reference material is mechanically constrained, enabling the detection of the polarization energy dynamics of constrained dielectrophoretic force indicating the presence of any target wi th dielectric properties identical to the properties of the reference material. An antenna assembly increases the proximity distance (range) of detection. The static electrification source for the reference material increases the longevity of the detection ability to provide continuous detection capability, and an external electronic circuit source of electrical energy via an electrical current surge gives a quantifiable manifestation of the detection. In accordance with the principals of dielectrophoresis, the detector can detect the presence of a specific material irrespective of the presence or absence of any type of intervening, visual obstructing material structures, barriers or electromagnetic interference (EMI) signals.

Abstract: The present invention comprises an apparatus and methods for making herbal extracts. The apparatus employs a percolation vessel having a filter and discharge valve. A heater is provided to heat the contents of the vessel to up to about 60°C during the cold percolation process. A control is provided to monitor the contents of the vessel and regulate the heater output to obtain and maintain the proper temperature. A pump draws the output of the vessel and recirculates it to the vessel top so that the vessel effluent passes through the vessel charge. The method entails continuously percolating a solvent through a bed of herbaceous material in the vessel at a temperature between room temperature and about 60°C to produce an extract comprising active principles contained in the herbaceous material. The thus produced extract is highly concentrated and contains a large proportion of the active principles in the raw material. The thus-produced extract can be used in lower unit doses to provide enhanced medicinal treatment.

Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the, efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.
