  • 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.

  • Patent number: 4835719
    Abstract: A payload monitoring system of a work vehicle includes a software controlled method of predicting when one additional bucketload of material will properly fill the vehicle to its rated capacity. The system calculates the actual magnitude of each bucketload of material and adds that value to the present payload to predict the future payload resulting from an additional bucketload of material. When the predicted future payload encompasses the rated capacity, the system signals the operators of both the work vehicle and the loading vehicle that one additional pass will complete the loading process.

  • Patent number: 4787890
    Abstract: The invention relates to a feeding system (1) for enteral feeding comprising a container (2) preferably constructed as a disposable article for receiving the food. Said container (2) is disposed in a suspension means (3) which is constructed such that the container (2) in the suspended state points with its opening (5) upwardly and assumes a position inclined to the horizontal. As a result when the tubing system (4) is introduced into the container for suppyling the nutrient solution to the patient no leaks can occur because the opening (5) points upwardly so that along the periphery of a piercing tube (17) introduced into the container (12) no solution can drip out. Nevertheless, due to the inclined position of the container (2) and the arrangement of the end of the inserted piercing tube (17) at the lowermost point (6) of the container (2) all the solution can be extracted; for this purpose for the extraction preferably a drip chamber (21) is provided in connection with a tube clamp ( 26).

  • Patent number: 4682156
    Abstract: An apparatus and method are provided for detecting solvents, including hydrocarbons. The apparatus includes a hydrocarbon-soluble plastic rod which interconnects a mass or weight and a weighing assembly. The weighing assembly is operatively joined to an alarm indicator, which is utilized to inform the user as to whether hydrocarbons are present. In a preferred arrangement, the weighing assembly is connected to a housing, which is joined to the top of a well casing provided in the ground. The plastic rod may be of any desired length, depending upon the depth of the well casing and where it is desired to check for hydrocarbons. When hydrocarbons are detected the plastic rod dissolves or separates causing movement of the weighing assembly and the alarm indicator so that a visual indication is provided that hydrocarbons are present. The apparatus further includes a mass catch assembly for maintaining connection between the mass and the housing after the plastic rod separates due to the presence of hydrocarbons.

  • Patent number: 4638674
    Abstract: Sample collecting system for gaseous or vaporous condensable radioactive substances contained in the ambient air, especially for collecting traces of tritium via the T.sub.2 O vapor content in the exhaust air of a nuclear plant. A gas stream of exhaust air is filtered and the filtered gas continues its flow through a suction branch line containing a measuring gas pump which propels the gas stream into and through a precipitate line. The precipitate line, enclosed in a measuring-gas cooler which is a cooling chamber, extends downward and then upward and then out of the cooling chamber, through a measuring-gas choke, through a flow transducer and the gas stream then returned to the exhaust gas flue or ambient air. The pump feeding the precipitate line has its pressure maintained constant by a bypass line and a pressure difference control valve from the output side of the flow transducer to the discharge side of the pump.

  • Patent number: 4137915
    Abstract: The flow control hereof is applied to a known system of feeding a patient intravenously and contemplates the use of a clamp applied externally to the delivery tube extending from the intravenous bag, bottle or other appropriate container to the patient, said clamp being selectively successively opened and then closed to correspondingly meter the feeding flow of the intravenous fluid on a selected volume per time basis, e.g. 1 cc/minute, so that intravenous feeding of the patient is achieved according to a desired time schedule. The external application of the clamp does not detract from conventional sterile conditions of the system. Also, and most important, the operation of the clamp is related to the weight of the intravenous fluid, which weight, if the feeding is proceeding as it should, should progressively diminish in a predictable way. The flow control hereof thus allows uninterrupted flow if the weight is not diminishing at the rate that it should; or it terminates flow, if the rate is too rapid.
