摘要:
A feeder is disclosed for dissolving a chemical and mixing it with a liquid. The feeder includes a hopper adapted to hold the chemical, a nozzle located in the hopper, and a supply of the liquid to the nozzle to dissolve the chemical on contact with the liquid from the nozzle to form a solution. A solution basin is disposed under the hopper and a drain is provided from the hopper into the solution basin. An outlet from the solution basin has an outlet valve which opens when a solution level in the solution basin rises.

A filter apparatus, a pressure relief apparatus methods are provided. The filter apparatus includes a tubular hull having an inlet port and an outlet port. A tubesheet partition separates the tubular hull interior into a first stage portion and a second stage portion. A plurality of filter elements are mounted in annular guides. A pressure relief apparatus is configured to relieve pressure through at least one of the annular guides with the pressure relief apparatus in parallel fluid circuit with the filter elements. The pressure relief apparatus includes an elongated tube, a sealing plug, an end cap, a rod disposed within the elongated tube with one end of the rod coupled to the sealing plug and another end of the rod coupled to the end cap; and a spring disposed in the elongated tube between the sealing plug and the end cap.

A moveable rotating electrical box assembly, which adheres to a wall that provides a housing for standard electrical outlet (prior art), GFCI electrical outlet (prior art) and other various prior art electrical outlet types. The electrical outlet box housing is connected to a tubular wire housing by a rotating collar. The rotating collar allows the electrical box to rotate in a desired orientation. The tubular wire housing extends towards an existing outlet. The tubular wire housing flanges at the end closest to an existing outlet to accommodate a rotating plug (prior art).
摘要:
A computer-implemented method that includes receiving a request to generate an interface within a software application that is configured to play back one or more media files; for a first media file, generating an image representing a frame of the first media file; and causing the image to be displayed within the interface on a display device, where the image is configured to detect an event that causes a media player to be loaded into the software application behind the image.

A system for monitoring a validator that assesses a token includes an input device for receiving messages from a machine including a validator. The messages contain data indicative of validator events such as an assessment of a token resulting in acceptance of the token and an assessment of a token resulting in rejection of the token. The system further includes a processor for deriving timing information for the validator events and for comparing the data and timing information with predetermined criteria. Personnel alerts are raised when predetermined criteria are satisfied, and maintenance of validators may be scheduled in dependence upon criteria related to assessments of tokens resulting in rejection.
摘要:
The present invention relates to derivatives of pyrimido[6,1-a]isoquinolin-4-one and their application as inhibitors of phosphodiesterase (PDE) isoenzymes. More particularly the invention relates to derivatives of pyrimido[6,1-a]isoquinolin-4-one and their use in medicine for example as bronchodilators with anti-inflammatory properties.
摘要:
Methods of establishing multimedia telecommunication (a multimedia “call”) between equipment (“terminals”). More particularly, the invention provides methods for reducing the time required to establish calls between terminals implementing ITU-T Recommendation H.324 and derived or related standards or recommendations such as 3G-324M. More specifically, it relates to methods and apparatuses for (i) concatenating H.245 messages to pass between the terminals at the start of the call to establish the capabilities of both terminals and agree on the type and format of media and data to be exchanged (ii) using non-standard H.245 messages or standard H.245 messages with non-standard fields to accelerate establishment and (iii) informing each terminal of the capabilities of the other and proposing the type and format of media and data to be exchanged by means of fields inserted in the call signaling protocol used for bearer establishment prior to the H.324 stage of the call.
摘要:
A method of initiating a set up process for a call between users with reduced set up times using one or more 3G telecommunication networks. The method is provided between at least a pair of H.324-like terminals coupled to the one or more 3G telecommunication networks. The method includes establishing a bearer channel between a first terminal and a second terminal after a call signaling process, transmitting a first FSS message from the first terminal to the second terminal. The first FSS message includes a first preference profile associated with a first mode of operation for the call and a second preference profile associated with a second mode of operation for the call. The method also includes selecting either the first mode of operation or the second mode of operation.
摘要:
Methods of establishing multimedia telecommunication (a multimedia “call”) between equipment (“terminals”). More particularly, the invention provides methods for reducing the time required to establish calls between terminals that implement the ITU-T H.324 Recommendation and other Standards and Recommendations derived from or related to this such as the 3G-324M recommendation developed and adopted by the Third Generation Partnership Projects (3GPP and 3GPP2). More specifically, it relates to (i) a method and apparatus for concatenating the H.245 messages that are required to pass between the terminals at the start of the call to establish the capabilities of both terminals and agree on the type and format of media and data to be exchanged (ii) a method and apparatus for using non-standard H.245 messages or standard H.245 messages with non-standard fields to accelerate such establishment and (iii) a method and apparatus of informing each terminal of the capabilities of the other and proposing the type and format of media and data to be exchanged by means of any user-defined fields that are inserted in the call signaling protocol that is used for bearer establishment prior to the start of the H.324 stage of the call.
摘要:
A method of establishing a session between a first device and a second device. The session is established over a telecommunications network using an accelerated session setup technique. The method includes providing a first accelerated session setup technique and providing a second accelerated session setup technique. The method also includes establishing the session using either the first accelerated session setup technique or the second accelerated session setup technique based on a predetermined process.
