Abstract: A device (10) for implementing a process, especially for the electrically induced agglomeration of gasbom particles has a flow channel (12) through which an aerosol containing particles (14) is taken. There is at least one pair of electrodes (20, 22) in the flow channel (12) to give the aerosol a bipolar charge; said electrode (20) is connected, without an earth to the positive terminal and said electrode (22) is connected without an earth to the negative pole of a current source, the power of which is sufficient to generate a corons discharge between the electrodes (20 and 22). The electrodes (20 and 22) of each pair are needle-shaped, insulated from the flow channel wall and arranged in such a way that their points face each other. It is possible with the device (10) to give an at least almost symmetrical bipolar charge to the aerosol taken through the flow channel (12) without there being any noteworthy particle deposition in the region of the electrodes (20 and 22) or in the flow channel (12).

Title: Model generation
Inventor: WHEADON NIGEL SPENCER
IPC: G01S13/02
Filed: 1995-04-24
Abstract: A model of the ionosphere for use in the operation of a skywave over the horizon radar is generated by taking a first map of heights of various ionospheric layers against location for at least one value of sunspot number and comparing this to the measured value of the layer height at at least one measurement point and calculating the value of the sunspot number which would give the closest fit of the ionospheric layer heights at that point with the measured value of height and using this calculated value of sunspot number to produce a second map of ionospheric layer heights against location. A respective local correction term is then applied to the height values in the vicinity of those locations on the map at which measurements have been made, the local correction term being derived from the covariance between the heights, the locations of the measured points and the difference between the measured values and the values predicted by the second map at the measurement points.

IPC: G01D5/14
Filed: 1996-10-24
Abstract: A rotation sensor for high accuracy angle applications such as internal combustion engine crankshaft position sensing includes a pair of complementary target wheels and a dual-element magnetoresistive sensor. The target wheels are spaced from one another along the rotational axis by a predetermined distance. The individual magnetoresistive elements are similarly spaced one from the other and are influence by the ferrite effects of the target wheels. The spacing of the target wheels and magnetoresistive elemlents are selected in relation to one another and in relation to the amount of axial play in the crankshaft such that changes in ferrite effects of the target wheels upon the elements due to axial displacements of the cranshaft have minimal effect on the accuracy of the sensing apparatus.

Title: Method and apparatus for speech recognition using optimised partial probability mixture tying
Inventor: DIGALAKIS VASSILIOS
IPC: G10L15/14
Filed: 1995-07-13
Abstract: In accordance with the invention, a speech recognizer is provided which uses a computationally-feasible method for constructing a set of Hidden Markov Models (HMMs) for speech recognition that utilize a partial and optimal degree of mixture tying. With partially-tied HMMs, improved recognition accuracy of a large vocabulary word corpus as compared to systems that use fully-tied HMMs is achieved with less computational overhead than with a fully untied system. The computationally-feasible technique comprises the steps of determining a cluster of HMM states that share Gaussian components which are close together, developing a subset codebook for those clusters, and recalculating the Gaussians in the codebook to best estimate the clustered states.

Title: Release assuring arrangement for combined electro-pneumatic/automatic pneumatic brake
Inventor: GAUGHAN EDWARD W
IPC: B60T13/66
Filed: 1997-05-02
Abstract: An electro-pneumatic brake control system for a railroad freight car comprises application and release solenoid valves controlled by a microprocessor overlayed with the conventional car automatic pneumatic brake control system, including means for bleeding off auxiliary reservoir pressure at least during a power failure mode of operation during which the pneumatic brakes become effective to apply the car brakes in response to an induced brake pipe pressure reduction in the course of indirectly supplying brake pressure on cars having operable electro-pneumatic brakes.          The bleed of auxiliary reservoir air pressure allows a subsequent slow recharge of the brake pipe pressure to create a positive release pressure differential across the control valve service piston to assure a brake release of the automatic pneumatic brake application to obviate a "stuck brake~ condition on a car experiencing an electro-pneumatic power failure.

Title: Railway crossing collision avoidance system
Inventor: WELK JAMES E
IPC: B61L29/24
Filed: 1997-07-14
Abstract: With the vehicle anti-collision system of the present invention, road vehicles in the vicinity of a railway crossing are alerted as a train approaches the crossing. A signalling device operating in conjunction with a GPS receiver located in the train emits a signal to a receiver located at the railway crossing to provide an indication of the rail vehicle's location with respect to the railway crossing. The signal is sent continuously at predetermined intervals to provide the railway crossing with sufficient data to estimate the velocity and time of arrival of the train or railway vehicle at the crossing. The railway crossing processes the information and transmits an alarm signal to approaching road vehicles as the rail vehicle approaches the crossing. The signal emitted by the crossing is received at the road vehicle which provides various levels of alarms depending on how close the rail vehicle is to the crossing. The communications between the railroad vehicle and the crossing monitor are preferably by satellite link. A sensor is also preferably provided at the crossing to detect an object on the crossing when the rail vehicle is approaching.

Filed: 1997-10-28
Abstract: A street sweeping vehicle has a generally centrally disposed longitudinal axis, a sweeping brush disposed laterally across the longitudinal axis for sweeping debris forwardly into an elevator disposed forwardly of the sweeping brush and laterally across the generally centrally disposed longitudinal axis, and opposed left and right drag shoes disposed on opposite sides of the longitudinal axis and laterally bordering the sweeping brush and elevator means.          The elevator lifts debris received from the sweeping brush into a hopper for subsequent controlled dumping therefrom.  Each drag shoe comprises a main body member having a front end and a back end.  A mounting assembly permits mounting of each drag shoe on the street sweeping vehicle in road tracking relation.  A bottom surface is shaped for substantially sealed contact with a road surface.  A generally vertically disposed inwardly facing side surface has a contacting portion  situated  in  intimately contacting  relation against the sweeping brush so as to substantially preclude debris passing between the contacting portion and the sweeping brush.  A first angled deflector surface having front, back, top and bottom edges  is  operatively mounted on  the  street  sweeping  vehicle proximate the side surface such that the front edge is disposed closer to the longitudinal axis than is the back edge.  The first angled deflector surface substantially precludes direct forward passage and causes inwardly angled deflection of an impacting portion of the debris swept forwardly by the sweeping brush.
