Abstract: FIELD: gas purification. SUBSTANCE: invention is aimed at electrically cleaning aggressive gases from high-resistance dust and are designed to dust removal from industrial gas outbursts in various industries. Method is based on cleaning gas stream in electric field of an electrofilter with electrodes made of low-alloyed types of steel covered with corrosion-resistant and heat-resistant coating applied by the aid of electric-spark alloying with ferrochrome. Coating also improves electrode recovery process. Strength characteristics of layer make it possible to deform blank sheets to produce desired type of precipitation electrode together with applied coating not provoking its shelling. By contrast to known methods of cleaning aggressive gases in electrofilter field wherein electrodes are made from expensive high-alloyed stainless steels, proposed method reduces cost of apparatus, increases its corrosion resistance and considerably widens range of accessible low-alloyed steels for manufacturing electrodes. Use of modern high-capacity mechanized plants including those using ultrasound, which increases velocity of alloying material erosion, allows the method to be recommended for treating electrodes of small electrofilters. EFFECT: reduced cost, enhanced efficiency, and prolonged service life of equipment.

Title: Display device drive circuit
Inventor: SASE ICHIRO
IPC: H01L51/50
Filed: 2002-11-12
Abstract: A display device drive circuit that enables high-precision fine-tuning of the drive currents. In this drive circuit, a plurality of current supply transistors are connected in parallel to each data line. A switching transistor is connected in series with each current supply transistor. When the switching transistors are ON, the drive currents from the corresponding current supply transistors are supplied to the data line. The magnitude of the drive current supplied to the data line is controlled by the number of switching transistors that are ON simultaneously. Consequently, when compared to a case in which the magnitude of the drive current is controlled by the gate potential on the current supply transistors, it is possible to perform precision control of the drive current values.

Title: Passive transmission line equalization using circuit board through holes
Inventor: GOERGEN JOEL R
IPC: H05K1/16
Filed: 2003-02-06
Abstract: A high-speed router backplane, and method for its fabrication, are disclosed. The backplane uses differential signaling trace pairs on multiple high-speed signaling layers, the high-speed signaling layers separated by ground planes. Plated signaling thru-holes connect the trace pairs to the board surface for connection to external components. The signaling thru-holes pass through clearances in each ground plane. At selected ground planes, a conductive pad is patterned within each high-speed signaling thru-hole clearance, the pad slightly larger than the thru- hole diameter. The pads affect the impedance characteristics of the thru-holes, thus providing a better impedance match to the differential trace pairs, reducing signal reflections, and improving the ability to signal across the backplane at high speeds.

Title: Methods and systems for effecting payment card transactions
Inventor: BARRY GERARD J
IPC: G06Q20/00
Filed: 2003-07-14
Abstract: The present invention relates to card payment systems. In particular, the present invention relates to systems and methods for processing payment card transactions in a dynamic currency conversion and/or multi-currency scheme. To operate correctly, ghost transactions are used. However to prevent duplication of debits against the card holder, these "ghost copy" transactions must not be processed into the card schemes with the normal transactions. Thus the acquirer's and/or third parties host systems have to be amended, in addition to modifications to the related accounting thereof. To overcome this necessity, the present invention provides a method for effecting the performance of a payment card transaction for a first transaction amount in a first currency, between a first merchant and a first payment card holder, the method comprising the steps of (a) creating a first payment card transaction record between the first merchant and a second cardholder for the first transaction amount, (b) creating a second payment card transaction record between a second merchant and the first cardholder, wherein the second transaction record identifies a second transaction amount in a second currency which equates to the first transaction amount converted into the second currency, and submitting the first transaction record and the second transaction record for processing as payment card transactions.

Title: Speed humps
Inventor: YANG CHIH-CHENG
IPC: E01F13/12
Filed: 2003-09-24
Abstract: The present invention discloses a mechanical road barrier embedded in a road surface, which can solve the drawbacks of the conventional speed humps. The conventional speed humps, although having different shapes and made of different materials, functions in the same way for all the automobile passing over it. This causes troubles to regulation-following drivers and may have damage to the automobiles, and is thus not suitable for most of the roads. The present invention is a speed hump having a raised barrier that is selectively lowered in accordance with the moving speed of an automobile passing it whereby vibration induced on the automobile to interfere with the moving of the automobile or stopping of automobile moving in opposite direction can be effected. The operation of the present invention is as follows: Wheels of an automobile move onto the barrier and a force is induced on the barrier to actuate an internal mechanism of the speed hump to determine whether to lower the barrier. The barrier and the associated mechanism are then operated in reversed direction and returned to the raised position by spring force for successive operation of the speed hump.
