  • Publication number: 20240302195
    Abstract: A flow meter run offers autonomous operation whilst improving measurement performance & confidence, increased safety and improving the total cost of ownership. A plurality of isolation valve assemblies each offer DBB (Double Block & Bleed) isolation to isolate a component or meter run section. This DBB isolation includes components being extracted from the main metering line. The meter run philosophy is detailed with use of a novel rotational orifice meter, though other flow meters may be substituted. The flow meter run also features extractable filters, a rotational and extractable flow conditioner which includes open and blind isolation components. The rotational orifice meter can house several independent orifice plates or nozzles and extractable sample probes and temperature elements. Further instrument sensors include the direct (non-inferred) measurement of density and/or viscosity. The system is configured for multiple sensors to monitor performance, autonomy, validation and isolation.

  • Publication number: 20240122384
    Abstract: An inflatable pillow decoration device for use only as a decoration includes a pillow having an exterior wall enclosing an interior space. The interior space is in fluid communication with an opening extending through the exterior wall of the pillow. The exterior wall further includes an inner layer bounding the interior space, a middle layer being resiliently compressible, and an outer layer being coupled to the middle layer. An inflation apparatus is positioned in the opening and is in fluid communication with the interior space. The inflation apparatus inflates the interior space and to warms the air being supplied to the interior space by the inflation apparatus.

  • Patent number: 11156299
    Abstract: A valve features an outer housing, in which there are provided inlet and outlet channels respectively reaching into the housing from inlet and outlet openings thereof. The two channels are axially closed at adjacent inner ends thereof, but feature perforated circumferential walls. A resiliently expandable sleeve is disposed around the circumferential walls in a position normally overlying the perforations, while leaving a gap between the sleeve and inner surfaces of the housing. A charging port communicates with the gap to enable pressurization thereof. Pressurization of the gap normally holds the sleeve tightly over the perforations to prevent flow from one channel to the other. When pressure in the inlet channel exceeds the pressure in the charging chamber, the sleeve radially expands from the circumferential walls of the channels to uncover the perforations and allow fluid to flow between the channels.

  • Patent number: 11150171
    Abstract: Described herein are systems and methods for the automated adjustment of flour property measurement equipment such as dough rheometers. The systems and methods allow measurements of flour and dough to be performed on different rheometers with consistent results, regardless of the manufacturer or location of the rheometers. The systems and methods described herein allow a second rheometer, for example, that is deployed in the field to provide results that are consistent with a first dough rheometer, for example, that may be at a different location, or the same location but of the same or different manufacturer. The systems and methods can be used to calibrate, remotely and in real-time, dough rheometers that are deployed in various locations.

  • Patent number: 9086305
    Abstract: In a flow meter, a rotor support body carries a paddlewheel rotor in an operational position exposed to a through-flow bore of a flow meter housing. A sensor unit is operable to detect rotation of the rotor and provide output responsive to same for use by a monitoring system in determining a flow rate of fluid passing through the housing. The support body and the sensor unit are removable from the housing, for inspection, service, repair or replacement independently of the housing, with the sensor unit being removable independently of the support body for improved serviceability. The rotor is carried on a support shaft with a reduced diameter portion for contact-free rotation of the rotor around this reduced diameter portion, reducing an area of the shaft over which tight machining tolerances are required to prevent ingress of particulate matter that can lead to inaccurate flow measurements and increased wear rates.
