  • Publication number: 20230221406
    Abstract: A sensor receiver may include a Rydberg cell configured to be exposed to a radio frequency (RF) signal having an RF data rate, and a probe source configured to generate a plurality of spaced apart pulsed probe beams within the Rydberg cell. Each pulse may have a temporal pulse width so that the RF data rate is greater than the reciprocal of the temporal pulse width. At least one excitation source may be coupled to the Rydberg cell. A detector may be positioned downstream from the Rydberg cell. The sensor receiver may be used in a RADAR system.

  • Patent number: 9512925
    Abstract: Disclosed is a manual balancing valve having an upstream end and a downstream end, and a first equalizing ring (500a) and a second equalizing ring (500b) configured at the upstream end and the downstream end, respectively. Each of the first and the second equalizing rings comprises an annular body (505) defined between an inner peripheral edge portion (510) and an outer peripheral edge portion (515), an annular chamber (520) configured adjacent to the inner peripheral edge portion, a plurality of holes (525) configured on the inner peripheral edge portion and in fluid communication with the annular chamber, and a pressure tap (T) in fluid communication with the annular chamber and extending radially outward of the annular body. The first and the second equalizing rings are adapted to provide static pressure value at each of the upstream and the downstream ends so as to measure differential pressure therebetween and control the fluid flow rate through the valve.

  • Patent number: 8714190
    Abstract: A metal plate for a dual plate check valve includes a substantially circular segment shaped plate member of a predetermined substantially uniform thickness and is pivotally mounted to enable rotation about an axis substantially parallel and adjacent to a chord. The plate member has a central portion and two extreme end portions distal to the central portion. The end portions are provided with reinforcements thereby increasing the thickness of the plate member in the end portions, the reinforcements being located so that when the plate member of the check valve is in a closed position, the end portions with reinforcements are in a radially outward direction from the valve seat of the check valve. When back pressure acts on the plate member, the reinforcements enable the plate member to distort substantially uniformly to maintain sealing contact with the valve seat.

  • Publication number: 20120042968
    Abstract: A metal plate (100) for a dual plate check valve comprises a substantially circular segment shaped plate member (1) of a predetermined substantially uniform thickness, a means (2) for pivotally mounting said plate member to enable rotation about an axis substantially parallel and adjacent to chord (3) of said circular segment of the plate member, said plate member (1) having a central portion and two extreme end portions (4) distal to said central portion, whereby said end portions are provided with reinforcements (5, 5?), thereby increasing the thickness of the plate member in the end portions, the reinforcements being so located that when the plate member of the check valve is in closed position, the end portions with reinforcements are in radially outward direction from the valve seat of the check valve, when back pressure acts on said plate member, said reinforcements enable said plate member to distort substantially uniformly to maintain sealing contact with the valve seat.

  • Patent number: 7974613
    Abstract: A device management (DM) technique wherein management objects (MOs) with device capability information are created and used for each feature domain or application. Each application installed in a mobile electronic device such as, for example, a cellular phone, a personal digital assistant, or a pager may provide device capability information that is stored as a management object or sub-node of a standard device management object, such as sub-nodes of the “DevDetail” management object in a DM tree in a mobile device compatible with the Open Mobile Alliance (OMA) Device Management (DM) specification, for example. The device capability information may be retrieved, for example, by a DM server or a customer care server in the form of extensible markup language (XML) data or an OMA UAProf-based device profile, to name only two possible forms.

  • Patent number: 6177374
    Abstract: This invention relates to a novel porous crystalline synthetic catalyst having the general formula expressed in the form of oxides: M 2/n o. x Al2O3 Y SiO2, Z ZnO wherein, M represents a proton and/or a metallic cation, n is the valence of the said cation, Y/x is a number ranging from 5 to 1000 (SiO2/Al2OS molar ratio), and a process for preparing such catalyst by (a) forming a reaction medium comprising water, a silicon source, an aluminium source, a zinc source and a source of structure directing agent capable of providing organic cations, (b) heating the said reaction mixture to a temperature ranging from 80° C. to 230° C. at autogeneous phase, and (c) heating the solid content obtained at the end of step (b) to a temperature greater than 400° C., so as to eliminate the organic species present due to the use of the structuring agent.
