Title: Exposure indicating apparatus
Inventor: YUSCHAK GREGORY
IPC: G08B21/00
Filed: 1995-09-11
Abstract: An exposure indicating apparatus for monitoring air flowing along a flow-through path extending from the external environment, through an air purifying respirator cartridge and into a face mask.      A reversible sensor is releasably attached to the flow-through path so that it can be removed without interrupting the flow of air along the flow-through path. A processing device generates a concentration signal responsive to at least one property of the reversible sensor. The processing device provides and active indication, such as audio, visual, or tactile response to the concentration signal. A  flow-through housing may form a portion of the flow-through path. The flow-through housing is preferably interposed between the air purifying cartridge and the face mask. A processor housing containing the processing device and indicator is attached to the flow-through housing or the air purifying respirator cartridge. The reversible sensor is located in the processor housing, the air purifying respirator cartridge or the flow-through housing. The sensor is coupled to the processing device by an optical, electrical, or general electromagnetic coupler covering the frequency range, for example, from DC to RF to microwave.

Abstract: A method and apparatus for charging the battery of an electric vehicle are provided; where charging energy is delivered from a charging station at a predetermined voltage and at a delivery frequency which is in the range of from 10 kHz up to 200 kHz. The charging energy is transferred to the vehicle through an inductive coupler, which has a primary side connected to the charging station and a secondary side mounted within the vehicle, together with a rectifier mounted in the vehicle and interposed between the secondary side and the traction battery to be charged. When the electric vehicle is connected to a charging station, it is interrogated to determine the nature of the charge controller that is on board the vehicle; and logic decisions invoking the particular mode for charging the vehicle are made depending on the nature and type of charge controller that is on board the vehicle. Thus, delivery of charging energy to the battery in the vehicle may be entirely under the control of a charge controller on board the vehicle; or, if the control module in the vehicle is less sophisticated, then delivery of charging energy will be under the control of a charge control module which is present within the charging station. The value of initial charging current is therefore set either by the on board battery charging control module in the vehicle, or by the charge control module which is present in the charging station; alternatively, the initial value of charging current may be preset at the charging station. That parameter, and the amount of charging energy to be delivered, may be established by insertion of a card into a data interface on the charging station. Under controlled conditions, a plurality of vehicles may be charged at a single establishment having a plurality of charging stations, by distributing energy to any vehicle according to priority criteria to be established.

Abstract: An intelligent digital beam former (10) in conjunction with a satellite based array antenna (20) provides a plurality of dynamically controllable antenna beams (52) for communication with subscriber units (90) in response to demand for communication services. Geographic portions within the satellite's footprint that have a higher-demand for communication services are dynamically provided additional antenna beams while geographic portions having a lower demand for communication services are provided less antenna beams. When used on a non-geostationary satellite, the digital beam forming coefficients are dynamically adjusted to steer the antenna beams to maintain their ground location. The antenna beams are also shaped to help optimized geographic coverage.

Abstract: Un joint pour un assemblage de cellules d'électrodialyse possédant une voie d'écoulement série comprenant une pluralité de sections de voie d'écoulement reliées par des sections de restricteurs. Chacune des sections de voie d'écoulement possède une largeur relativement importante. La largeur du restricteur est inférieure à la largeur importante afin qu'un fluide circulant dans la voie d'écoulement série ait besoin d'augmenter sa vélocité lors de son écoulement au travers du restricteur. Il en résulte que le fluide sortant du restricteur cause turbulence et agitation dans les sections de voie d'écoulement. De multiples trous sont situés aux extrémités opposées de la voie d'écoulement série. Un orifice rigide est placé entre chacun des nombreux trous et les extrémités de la voie d'écoulement série. Les cellules successives de l'assemblage sont définies par une paire de membranes bipolaires avec cation et/ou de membranes d'échange anionique entre elles. L'un des joints est situé entre chacune des deux membranes.

Title: Nozzle for producing a high-impact long-range jet from fan-blown air
Inventor: DAVIDSON JOHN FREDERICK HAYDEN
IPC: B05B1/00
Filed: 1998-03-10
Abstract: Blow-off nozzles are used for creating a high-energy air blast, for drying metal panels prior to painting. Depth or reach of penetration (in the atmosphere) is important. A bullet is provided in the centre of the nozzle. The bullet is aerodynamically faired, for minimum drag. The effect of the bullet is to create a low pressure area in the jet downstream of the nozzle. The low pressure area serves to hold the jet together, preventing spreading, to a degree that enables a significant increase in penetration distance.      The bullet is mounted on faired arms, which are secured to the walls of the nozzle.
