  • Patent number: 9885797
    Abstract: An acoustic logging tool is disposed in a wellbore during an acidizing operation. Measurements are made using the acoustic logging tool on a region of a formation penetrated by the wellbore and being subjected to the acidizing operation. An acoustic anisotropic property of the formation is inferred at one or more depths of investigation within the region using the measurements, and a wormhole porosity and/or an orientation of one or more wormholes resulting from the acidizing operation is determined. Acidizing operation management decisions may be made based on the determined wormhole porosity and/or orientations of the wormholes. An acidizing operation management decision may be to maintain, increase, or decrease an acid injection rate. Measurements made may include the velocity of an acoustic wave propagating through the formation and the acoustic anisotropic properties of fast waves and slow waves. The acoustic anisotropic properties of the formation generally depend on rock stiffness.

  • Patent number: 9861755
    Abstract: The present invention relates to a torsion spring driven injection device for delivering multiple set doses of a liquid drug from a cartridge by moving a plunger forward inside the cartridge. The torsion spring (134) applies a rotational torque onto a drive member (120) engaging a piston rod (115) which is then driven forward by this rotation. The piston rod driver can be coupled and de-coupled from the torsion spring mechanism. In the de-coupled position, the piston rod driver is freely rotatable and can thus rotate if the piston rod is moved axially. A further torsion arrangement (124) is preferably provided such that a torque is build up between the piston rod driver and the housing whenever the piston rod is moved backwards. This torsion arrangement urges the piston rod driver to rotate in a direction bringing the piston rod forward into abutment with the plunger.

  • Patent number: 9169838
    Abstract: A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

  • Publication number: 20150050161
    Abstract: An air operated diaphragm pump is provided featuring a housing, a fluid passageway and an indicator arrangement. The housing is configured with an orifice. The fluid passageway responses to a vacuum force and provides fluid, such as syrup from a bag or container to a beverage dispenser, through the air operated diaphragm pump via the fluid passageway, and is configured with a suction plenum or channel formed by an enclosed space with an inside pressure that is greater than an external pressure of the outside atmosphere when the fluid is being provided through the air operated diaphragm pump via the fluid passageway. The suction plenum or channel is configured to be in fluidic communication with the orifice of the housing.

    Abstract: Described herein is technology for, among other things, controlling a pump submersed in a liquid, where the pump includes a plurality of capacitive sensors. The capacitive sensors include a first capacitive sensor and a second capacitive sensor disposed above the first capacitive sensor. The technology involves sensing liquid levels with the capacitive sensors, activating the pump after the second capacitive sensor detects the liquid in a normal mode of operation, deactivating the pump after the first capacitive sensor no longer detects the liquid in the normal mode of operation, detecting a failure of one or more capacitive sensors, and adjusting the operation of the pump to compensate for the failure of the one or more capacitive sensors.

  • Patent number: 8905730
    Abstract: A peristaltic pump comprises a pump unit including a pump which receives a replaceable tube. The tube has a transponder, for example an RFID tag, which carries data relating to the tube, which can be read by a reader of the pump unit. On the basis of a comparison between the tube data on the RFID tag and control data held in a memory of the reader, the reader permits operation of the pump unit if the tube data is compatible with the control data, but prevents such operation if the tube data is incompatible with the control data, for example indicting that an incorrect tube has been fitted, or the tube is approaching the end of its predicted operational life.
