Granted: 1999-04-06
Abstract: An alerting device, such as a radio (10), activates, responsive to the times when an information signal (12) is received, a silent alert, via a vibrator (24), during a first predetermined time period, and an audible alert, via a loudspeaker (22), during a second predetermined time period, exclusive of the first predetermined time period. A radio user can configure the priority and the duration of the silent and audible alerts. The radio (10) also detect the reception of the information signal and the intercoupling between an accessory 51 to the radio 10. Responsive to the detection thereof, the radio (10) activates the audible alert. Thus, the user gains a high degree of confidence that the radio (10) will activate the proper alert in situations having a wide range of ambient noise levels and distances of the radio relative to the user's body.

Title: Process for continuously controlling the heat content of a partial oxidation unit feed-gas stream
Inventor: SUGGITT ROBERT MURRAY
IPC: G05D21/02
Filed: 1995-06-01
Granted: 2007-04-03
Abstract: A process is provided for continuously controlling the hydrocarbon heat content and flow rate of a partial oxidation unit feed-gas stream under conditions where the composition and hence the hydrocarbon heat content of the feed-gas stream is subject to variation. The hydrocarbon heat content of the incoming gases is continuously measured and compared against a design hydrocarbon heat content. An evaluating means calculates whether a moderator is required to decrease the hydrocarbon heat content to the design hydrocarbon heal content or a supplemental high hydrocarbon heat content gas is required to increase the hydrocarbon heat content to the design hydrocarbon heat content. The process utilizes recycle synthesis gas as a moderator. Once the determination is made, the process automatically adjusts flow rates of the recycle synthesis gas stream, the supplemental high hydrocarbon heat content gas stream and the incoming feed- gas stream to provide a partial oxidation unit feed-gas stream with a constant optimum hydrocarbon heat content and flow rate.

Granted: 2000-06-27
Abstract: The catheter includes a catheter hub at its proximal end having a radially extending wing. The needle is connected at its proximal end to a needle hub. The needle may have at least one notch therein. The needle hub defines a radially extending fin thereon. When the introducer needle is inserted through the catheter such that the distal tip of the needle extends beyond the distal tip of the catheter, the fin on the needle hub extends beyond the distal end of the wing on the catheter hub. This arrangement allows the distal tip of the needle to be retracted into the catheter with a simple proximal motion by the healthcare worker.

Abstract: A drill pipe protector comprises an annular body (820) adapted to surround a drill pipe (824) in a borehole to protect the drill pip e and borehole (or borehole casing) against damage caused by contact between the two, such that the drill pipe may rotate freely withi n the annular body upon contact between the body and the borehole (or borehole casing), so as to reduce the torque and drag produced by su ch contact. The assembly may further include annular clamps (822) secured to the drill pipe (824) to restrict the longitudinal movement of the body along the pipe. Various features of such assemblies are disclosed including features of the shape and configuration of the annular body and clamps, the use of bearing members on the internal and external surfaces of the annular body and between the body and the clamps or drill pipe joints, and materials for use in the fabrication of the body and bearings. These are particularly concerned with optimising the bearing arrangements to promote thin film lubrication and to employ sacrificial self- lubrication when such thin film lubrication breaks down, configuring the assembly to promote fluid flow around and through the assembly and the avoidance of snagging of the assembly on downhole obstructions.

Abstract: Automatic call forwarding techniques for use in conjunction with a telephonic communications system such as a PBX or a central switching office. A telephonic device is associated with a smart card reader/writer and a communications unit RF transceiver. Subscribers are each provided with a smart card and an RF jacket transceiver adapted to partially and removably encase the smart card. In response to input received from the smart card reader/writer, the telephonic device instructs the communications system to forward incoming telephone calls for a given subscriber to the associated telephonic device. The communications unit RF transceiver periodically transmits an interrogation signal to the RF jacket transceiver. If the interrogation signal is received by the RF jacket transceiver, the RF jacket transceiver sends an acknowledgment signal to the communications unit RF transceiver, and incoming calls will continue to be forwarded to the associated telephonic device. However, if the interrogation signal is not received by the RF jacket transceiver, the RF jacket transceiver does not transmit an acknowledgment signal, the communications unit RF transceiver does not receive the acknowledgment signal, and the communications unit RF transceiver causes the associated telephonic device to instruct the communications system to no longer forward incoming calls to the associated telephonic device. In a further embodiment, if the interrogation signal is not received by the RF jacket, incoming calls continue to be forwarded to the associated telephonic device until a predetermined time interval elapses, whereupon incoming calls are no longer forwarded to this associated telephonic device.

Abstract: A method and apparatus for determining the location of a communication unit in a CDMA system includes in a first embodiment, sending a location request via a spread spectrum signal to the subscriber (140), and receiving in return a subscriber signal including a response message showing a receive time of a particular symbol of the base's spreading sequence and a transmit time of a particular symbol of the subscriber's spreading sequence. The base (130), along with other receiving base(s) (140), also receives a predetermined symbol of the subscriber spreading sequence, and each determines a respective receive time of the predetermined symbol. The received information is then processed, along with known base location and delay information, to determine the subscriber location. If insufficient number of bases are capable of communicating with the subscriber, for example due to high loading/interference, auxiliairy bases (121) are also provided for receiving from or transmitting to the subscriber.
