  • Patent number: 5321408
    Abstract: A microwave apparatus and method for ullage measurement of agitated materials is provided. The apparatus and method utilize a transformation of the reflected time domain signal into a frequency domain signal. The frequency domain signal is averaged using the natural, inherent weighting associated with the transformation to achieve a unique corrected result. The average frequency domain signal is then used to calculate the average distance for determining the ullage measurement.

  • Patent number: 5319298
    Abstract: A current limited, voltage regulated, battery maintainer and charger apparatus includes a circuit for monitoring and maintaining a 12 volt storage battery, determining the presence of forward polarity and in response controlling the amount of charging current necessary to continuously maintain the battery in a ready state, without overcharging or causing other damage to said battery. The battery maintainer device selectively charges 12 volt lead acid, gel-cell or sealed lead acid batterys using current limitation and voltage regulation circuitry, to modulate an amount of current to maintain a voltage potential across the battery, whereby the current flow can drop to zero current flow, to maintain a constant and continuous storage battery voltage of 13.8 volts.

  • Patent number: 5316292
    Abstract: A simple, brightly colored, plastic collar is disclosed for greatly enhancing the visibility of the golf hole for players, spectator and televised golf events. The collar has a diameter essentially the same as a regulation hole and is installed in the cup adjacent the exposed earth wall between the lip of the hole and the hole liner. Furthermore, use of the collar enhances a retention of moisture in the earth around the lip to prevent drying and crumbling of the soil which can cause an initially sharp lip to become rounded. The collar preferably has a thinner upper perimeter wall to insure that the reaction of an impinging golf ball against the cup wall having the collar installed is not substantially altered from the reaction of a ball impinging an earth surface of a cup not having the collar installed.

  • Patent number: 5312040
    Abstract: The present invention relates generally to a non-clogging slurry nozzle apparatus and method for avoiding blockages in slurry nozzles associated with the jetting of mixtures of soluble and/or insoluble abrasives and high pressure fluids. The apparatus involves the use of a pressure actuator which opens and closes gates of a valve, permitting a compressed gas to enter the nozzle and remove all abrasive material from a nozzle when jetting is interrupted, thus preventing the abrasive material to remain in the nozzle where it may adhere with residual moisture and form blockages. The present invention lessens the opportunity for abrasive material blockages in slurry nozzles and improves the efficiency of cleaning operations by reducing the need to interrupt blasting operations to remove abrasive blockages from the slurry nozzle.

  • Patent number: 5255074
    Abstract: A concentration measuring apparatus is provided having a fluid sensing means, an optic transmission means, a signal processing means, and an interface means. The fluid sensing means comprises a reflective sensing media in a self-contained cassette. The cassette is operationally associated with a sample chamber. The cassette advances the reflective sensing media by a motor which is driven by the signal processing means. The optic means comprises a fiber optic line which is partially associated with a lamp and partially associated with a photocell. Light having a wave length in a specified range originates from the lamp, passes through a portion of the fiber optic cable and is cast upon the reflective sensing media. The altnerate portion of the fiber optic cable receives the reflected light from the reflective sensing media for transfer to the photocell. A signal is generated by the photocell representative of the change of reflectivity of the light from the reflective sensing media.

  • Patent number: 5101367
    Abstract: Disclosed is a method and apparatus for measuring the percentages of oil and water present in an oil/water mixture. By measuring the energy absorption properties of the oil/water mixture, the percentages of oil and water present in the oil/water mixture can be determined regardless of whether the oil or the water is in the continuous phase and regardless of what the relative proportions of water and oil are. Measuring the energy absorption properties of the oil/water mixture yields a current output which can be plotted on one of two distinct, empirically or theoretically derived data curves. One of the data curves represents oil being in the continuous phase and the other data curve represents water being in the continuous phase. A comparator is used to determine whether the oil or the water is in the continuous phase to thereby select the proper data curve on which the energy adsorption is plotted.

  • Patent number: 5082013
    Abstract: A system consisting of multiple independent units each of which includes two standard fire hydrant connections located on two riser pipes and an interconnecting underground pipe providing a means for drafting tide, lake or river water from a streetside conneciton. Any pumper/tanker truck can thus connect a suction hose to the streetside riser and draft water through a second suction hose with one end connected to the riser at a bulkheaded waterside location and the other end equipped with a strainer is lowered into the water source. Standard lengths of fire hose suffice at both water and streetside connections when the water is bulkheaded and water level variations are sufficiently small that the lift capability of the pump is not exceeded. Pumping many begin when connections are complete. Backflushing with fresh water carried on the pumper/tanker may be performed if the pump is not well sealed and pumping begins after backflushing is complete and flow direction is reversed.

  • Patent number: 5047089
    Abstract: A device for removing and cleaning asbestos containing material from a surface is disclosd. The device has a housing which is moved in a path to clear a swath of asbestos-containing material from a surface. A plurality of knives are positioned on an open face of the housing to make a plurality of incisions in the asbestos-containing material layer as the housing is moved along the surface. A scraping blade trailing the knives scrapes the asbestos-containing material from between the incisions. A sheet of water from a pressurized source is sprayed onto the scraped surface at an oblique angle to wash residual asbestos-containing material from the surface. The liquid spray and asbestos-containing material is aspirated together by a vacuum source connected to the housing, and the mixture of liquid and asbestos-containing material is removed in a separating receptacle.

  • Patent number: 4929890
    Abstract: A method and apparatus are disclosed for deriving digital signals from analog variations of different sensing elements in a transducer. Each sensing device controls the frequency of a variable frequency oscillator, which is energized when a reading is to be taken for that specific sensing device. The periodic signal is coupled to a first counter which counts a presettable total number of cycles so as to establish a variable time period proportioned to the value represented by the then existing state of the sensing device. Concurrently, a second counter is operated for a like time interval, but counts cycles from a fixed frequency clock source at a much higher frequency. The number of cycles counted by the second counter is proportional to the analog signal from the sensing device. This arrangement enables the analog signals from the sensing devices to be digitized in sequence with compact circuitry having low power drain.
