With Float Operated Valve Patents (Class 73/221)
  • Patent number: 8468884
    Abstract: A pipeline apparatus has a body configured to fit inside a pipeline. A flow channel is formed within the body and includes an inlet, an outlet, and a bypass channel connecting the inlet and the outlet, the inlet being configured to receive a portion of a fluid flowing through the pipeline, and the outlet being configured such that the fluid flowing through the bypass channel flows out of the bypass channel through the outlet. A flow control valve is attached to the body and has a sleeve configured to move to vary a flow rate of the fluid flowing out of the outlet. A motor is provided in a chamber in the body and is configured to move the sleeve.

  • Patent number: 5111201
    Abstract: System for radio transmission of level data of liquid contained in a tank and for converting to the level data to volume data to be indicated. A transmitter includes a cell for supplying electric power, a microcomputer connected to the cell and normally dept in a standby state in which it consumes a small amount of electric power. A timer is connected to the cell and the microcomputer to provide the latter with activation signals to place it in a activated state at a predetermined interval. A level detector if supplied with electric power from the cell only when the microcomputer is activated to provide the level data. A memory is continuously supplied with the electric power from the cell to memorize the level data, and a modulator supplied with the electric power from the cell only when the microcomputer is activated to transmit the level data in the memory by carrier waves through an antenna, whereby the system saves power consumption of the cell.

  • Patent number: 4530370
    Abstract: An apparatus and method for measuring predetermined amounts of liquid additives, such as a detergent, acid, and/or a sanitizer which may then be automatically dispensed during a cleaning cycle of the dairy pipeline cleansing system. The apparatus includes metering chambers for each of the liquid additives which are connected by a supply line to respective bulk containers. A vacuum source is connected to the metering chambers through an intermediate trap chamber. A valve assembly is provided within each of the metering chambers to block off the vacuum source once the chambers are filled to the desired level. Valves are provided in each of the metering chambers for dumping the respective liquid additive into the cleaning system tank at a selected time.

  • Patent number: 4500322
    Abstract: An apparatus for regulation feed for gas consumption from a source with a variable gas production. The apparatus is characterized by two chambers (1, 2). These communicate in their lower parts with each other. At least the first chamber (1) is closed in its upper end. The lower part of the chambers (1, 2) is provided with a gas inlet (3) from said source for gas production and a gas outlet (5) to said consumer. In the second chamber (2) there is provided a means (15) regulated by the liquid level for starting and shutting off the gas consumer.

  • Patent number: 4437346
    Abstract: The milk weight is accurately determined by a vertical elongate float (6, 46) in the measuring container (1) cooperating with a stationary switch (10). This switch actuates the supply (3) and discharge (5) valves in the container when the float reaches its uppermost position and at the same time issues a signal to a registration counter (not shown) for the milk quantities received in the container.The sampling device either has a sample holder (8) below the measuring container (1), comprising a sample receiving volume (11) with open upper end, or an aperture (52) in the discharge valve (49) seat (50). Thereby in operation a proportional portion of the milk quantities passing through the measuring container (1) is collected in a mixing beaker (23), from which a sample bottle (28) may be filled.
