Title: Exhaust gas dry cleaning agent
Inventor: KIENOW EKKEHARD
IPC: B01J20/20
Filed: 1994-02-04
Abstract: A powdery agent for cleaning exhaust gas, for example flue gas, according to the dry adsorption principle, consists of a mixture of active cokes with inert materials with no dust explosivity. In order to prepare a powdery, active coke-containing mixture with up to 30 % by mass carbon which when used in a gas flow cleaning-process could not experience in none of its fractions a concentration shift leading to the formation of dust explosive fractions at oxygen concentrations of up to 21 % by volume, whatever the operation conditions, the grain size distribution of at least one inert component is adapted to the grain size distribution of the active coke component so that in a gas medium at rest the settling speed of the top grains of the inert component is equal to or greater than the settling speed of the top grains of the active coke component.  This agent may be used in all flue gas cleaning plants in separately driven, upstream or downstream adsorption stages operated according to the gas flow cleaning principle.

Title: Postage evidencing system with secure summary reports
Inventor: PINTSOV LEON A
IPC: G07B17/00
Filed: 1995-09-14
Abstract: A method of verifying a summary activity report representing the total postage expended by a postage meter for a given activity period per preselected postal categories is accomplished by generating a hash value representative of the postal transactions of the postage meter. As a first step, each transaction is recorded in the memory unit of the postage meter. The funding activity records are then retrieved from said memory unit by recorded postal category for the selected activity period. A hash value is then calculated for the retrieved records. The calculated hash value is encrypted and printed along with the retrieved record of funding activity. The printed report including the encrypted hash value is then inputted into a verification apparatus by either key entry or optical scanner. The verification apparatus  then independently calculates a hash value based upon the inputted record of funding activity and generates an encrypted hash value representative of the inputted funding information. A comparison is now between the now derived encrypted hash value to the encrypted hash value generated by said verification apparatus. If the report has not been altered that the encrypted hash values will be identical.

Inventor: LEBLANC DAVID
IPC: B63H9/04
Filed: 1996-06-05
Abstract: Many methods of harnessing wind energy have been attempted throughout humanities history. The two main uses being for electrical or mechanical energy itself and to assist transportation. Most notably for the latter is the various sail and mast ensembles. Almost all methods to date employ a fixed system (ie. fixed sails to mast, fixed turbine or windmill). The two main exceptions to the fixed systems would be broadly represented by kite sails and parachute sails. These two novel categories have severe limitations but many unique advantageous over fixed systems. A simple category which must now be added to this short list is one in which a standard type sail is utilized (for example a spinnaker) but a mast is not required for it is held aloft from above by the buoyancy of a lifting agent (a lighter than air gas or heated air). Thus the simplest example being a large spinnaker sail with a relatively small lifting balloon affixed to the top corner (ie. weather balloon).

Abstract: A physically realizable one terabit or more ATM packet switch that has a large number of input interfaces connected to a single stage switching fabric which is in turn connected to a number of output modules, generally according to the growable packet switch architecture. This ATM packet switch is different from other growable packet switches in that it has a single stage switch fabric controlled by an out-of-band controller, yet it has significantly reduced complexity with respect to comparably sized electronic crossbar switches or their isomorphs. The out-of-band controller has multiple priority levels in order to provide high priority users with a near certainty that their packets will be successfully routed, while delivering an acceptably low packet or cell loss probability to users at the lowest priority level.

Patent CA-2187952-A1 (CA)
Inventor: TAYLOR RICHARD STEPHEN
IPC: H01Q1/08
Filed: 1996-10-16
Abstract: In systems carried by aircraft that transmit and receive electromagnetic fields for geophysical exploration, it is known to mount transmitting antennae on an aircraft or other rigid structure attached to or towed beneath an aircraft. In every case, the area of the transmitting antenna is limited by the dimensions of the rigid structure, which limits the dipole-moment of the antenna and thus the strength of the signal received by the system. This limitation is particularly severe for systems using antennae in towed structures. The present invention consists of a system that incorporates an airborne electromagnetic transmitting antenna with flexible area. Before take-off and during landing, the area of the antenna may be collapsed for safety and convenience. In flight, the antenna assumes a large and stable area, which induces strong electromagnetic responses from conductive features in the earth.

Title: Sliding interleaved motsa for magnetic resonance imaging
Inventor: LIU KECHENG
IPC: A61B5/055
Filed: 1996-10-16
Abstract: A method for the elimination of slab boundary artifact (SBA) or venetian blind artifact in three dimensional multiple overlapped thin slab acquisition (3D     MOTSA) for magnetic resonance angiography (MRA). The method uses a sliding slab, interleaved K-space MOTSA (SI-MOTSA) data acquisition strategy, equalizing flow-related signal intensity weighting accross the entire slab dimension. The method demodulates signal intensity changes along the slab direction and can essentially eliminate the SBA while retaining the same or better imaging time efficiency as that of conventional MOTSA, providing robustness to complicated flow patter and thereby resulting in more accurate depiction of vascular morphology. In addition, the method does not need specialized reconstruction and extra computation.
