Title: Reduced Q low frequency antenna
Filed: 2011-06-29
Abstract: A rod antenna and antenna circuit are described which make use of negative feedback to reduce the Q of the antenna, but which also makes use of a different coil tapping arrangement to significantly reduce electric field susceptibility on the detected signal from the main coil as well as different biasing arrangements to reduce noise. More particularly, in some embodiments of the invention the main detector coil of the antenna has a centre tap that is AC grounded with signal taps then being taken from the opposite ends of the main coil, and being respectively fed to the inputs of a differential amplifier. The output of the differential amplifier is then fed to the magnetic circuit of the rod antenna via a second inductor winding that is magnetically coupled to the resonance circuit of the main antenna coil. The AC grounding of the centre of the main coil significantly reduces susceptibility of the coil to the electric field. In addition, in one embodiment plural such circuits may be provided, with the antenna and feedback coils magnetically coupled. By having each antenna coil tuned to a different frequency, a multi-band or wideband overall antenna may be obtained.

Title: System and method for subscribing to events based on tag words
Filed: 2011-07-28
Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for creating tag subscriptions and notifying users based on tag subscriptions. A system configured to create tag subscriptions receives from a user, as part of a tag subscription request, a tag, a selection of at least one media event to which the tag is to be applied, and a notification threshold. The system then establishes a tag subscription associated with the user based on the tag, the selection of at least one media event, and the notification threshold. A system configured to generate tag notifications based on a tag subscription retrieves a tag subscription including a tag, a selection of a media event, and a notification threshold. The system then monitors tags generated in association with the media event for matches with the tag, and sends a tag notification to a user when matches exceed the notification threshold.

Title: Process for producing deuterium-enriched water during the production of hydrogen
Inventor: MANDRIN CHARLES DR
IPC: C01B5/02
Filed: 1981-05-23
Granted: 1983-07-07
Abstract: The synthesis-gas plant is operated in a number of successive operating periods such that during the first operating period an excess of fresh water is supplied to the synthesis gas plant and the waste water from the resulting mixture is separated in a condenser and supplied to a storage container. During the subsequent operating periods, the waste water stored in the container is used as the feed water for the synthesis gas plant and the waste water obtained on each occasion is stored in the container with increasing deuterium concentration. The waste water obtained during the last operating period and having the highest deuterium concentration is used to feed a plant for producing heavy water. This process, when used in a synthesis gas plant for producing hydrogen, can be used to obtain deuterium-enriched water as a feedstock for a heavy-water plant without expensive additional energy-consuming devices.

Title: Apparatus for gathering data from a plurality of condition responsive optical sensors
Inventor: HALSALL JAMES RICHARD
IPC: H04J99/00
Filed: 1981-11-24
Granted: 1985-07-18
Abstract: Apparatus for gathering data about a plurality of chemical or physical conditions, e.g. on industrial plants, utilizes a plurality of passive optical sensors. Light for the sensors is provided by a common broadband source, and distributed by an optical fiber from which light of a selected color is withdrawn for each sensor in turn, the color selected for each sensor being different from that selected for the other sensors. Each color is modified by its respective sensor as a function of changes in the conditions applied to the sensor, and all the modified colors are conveyed along a common data bus to be demultiplexed and the data displayed. The colors may be supplied by the data bus to detection means simultaneously or sequentially. Passive optical sensors avoid electrical interference and incendiary risks due to electrical sparking, and color multiplexing avoids difficulties associated with other forms of multiplexing in plant environments.

Granted: 1985-10-03
Abstract: A target structure for use with an alignment apparatus, such as a line of sight alignment apparatus for detecting the alignment of wheels of vehicles such as automobiles, truck tractors and trailers comprises an adjustable, wheel engaging and target supporting structure mountable upon a vehicle wheel rim. The target structure has an inner wheel mounting member with upper and lower arm members extending therefrom and engageable with the vehicle wheel rim. An outer target mounting member is pivotally connected to the inner wheel mounting member through coaxial center portions thereof for relative rotation of the outer target mounting member relative to the inner wheel mounting member. The outer target mounting member has spaced shaft members extended outwardly of the wheel and holding a plurality of targets at cardinal points around the wheel, the targets providing scales for determining the angular position of the vehicle wheels for conventional measurements such as caster, camber, toe and kingpin inclination. A sighting instrument establishes a line of sight parallel to and longitudinally spaced from the vehicle and which is directed toward a target and impinges upon a discrete mark on the scale thereof. Comparison of the points of impingement upon targets located at opposite cardinal points of the wheel establishes angular relations therebetween which correspond to alignment measurements.
