Patent CA-2080041-A1 (CA)
Inventor: NAEINI ABDOLREZA S
IPC: H04J3/00
Filed: 1992-10-07
Abstract: METHOD AND SYSTEM NETWORK FOR PROVIDING AN AREA WITH LIMITED BANDWIDTH BI-DIRECTIONAL BURST PERSONAL TELECOMMUNICATIONS ABSTRACT A unique combination of frequency and time division multiplexed communications is presented to enable bi-directional burst communications between a substantial number of users over a single radio frequency communications channel. A service area for communications is divided into a number of cells, with the cells arranged into clusters. Cells in each cluster are similarly numbered with no two adjacent cells across the service area having the same number. The clusters are also numbered in the same manner. A cellular time division multiplexed waveform is used by the network to carry communications with each cell number and cluster number assigned a time slot. During the time slot corresponding to the cell or cluster number, all cells or clusters having that number will be simultaneously transmitting. This networking technique enables time slots to be reused across the service area.

Patent CA-2095897-A1 (CA)
Inventor: COLE EUGENE H
IPC: B26D3/18
Filed: 1993-05-10
Abstract: ABSTRACT OF THE DISCLOSURE   A knife blade and knife blade assembly are disclosed for cutting food products into sticks or slices without causing surface cracking. The knife blade has a cutting portion defining a cutting edge and is mounted in the knife assembly such that a tension force is exerted on the knife blade in the plane of the cutting edge. The cutting edge of the knife blade is not sharp, but is generally flat and extends between parallel sides of the knife blade. The individual knife blades are formed of stainless steel and are electro-polished to remove any surface defects or sharp edges which may produce stress concentrations. This enables a significant tension force to be applied to the knife blade without diminishing its useful life. The electro-polishing process may also round off the comers of the juncture between the flat cutting edge and the parallel knife blade sides.

Title: Low emission combustion system for a gas turbine engine
Inventor: ETHERIDGE COLIN J
IPC: F23D17/00
Filed: 1991-12-26
Abstract: The control systems for reducing NOx in the combustion systems of past gas turbine engines has incorporated a variety of expensive and complicated techniques to reduce the NOx level. For example, such systems use schemes for introducing more air into the primary combustion zone, recirculating cooled exhaust products into the combustion zone and injecting water spray into the combustion zone. The present system (12) reduces the formation of NOx within the combustion zone by controlling the air/fuel ratio and more explicitly by controlling the air portion of the air/fuel ratio.  The present system (12) includes a device (260) for directing a portion of the flow of compressed air exiting a compressor section (22) into an injection nozzle (60, 180, 330) and into a combustor (40), a device (298) for reducing the flow of compressed air into the combustor (40). The system (12) monitors an engine (10) parameter, such as a power turbine (30) inlet gas temperature, sends a signal to a computer (314) which interpreters the signal and directs a second signal to a power cylinder (320) which causes a throttling mechanism (288) to move between an open position (296) and a closed position (294) depending on the temperature of the gases. The system (12) provides an economical, reliable and effective method for reducing and controlling the amount of nitrogen oxide (NOx), carbon monoxide (CO) and unburned hydrocarbon (UHC) emitted from the gas turbine engine (10).

Patent CA-2109464-A1 (CA)
Title: Optical switch
Inventor: BUELOW HENNING
IPC: G02F1/35
Filed: 1993-10-28
Abstract: Abstract Optical Switch For so-called add-drop multiplexers, fast optical switch-es (SCH) are needed which can switch optical signal waves stemming from different signal sources.            Known optical switches include an interferometer in which the signal wave is split into two signals, and in which an optical switching pulse is superimposed on one of the signals. Because of the Kerr effect, in-terference signals can be generated which can be switched in an optical coupler in a controllable manner to a predetermined output. The signals and the switching pulse have the same direction of polariza-tion, which may cause may cause switching problems with signals from different signal sources.           The gist of the invention therefore lies in the use of switching pulses which consist of quasi-depolarized light. Such switching pulses are advantageously gene-rated in two switching-pulse sources (SQ) in which two polarized light beams are superimposed orthogonally. In an optical waveguide (LWL1, SP) with a nonlinear refractive index, the switching pulse assumes a con-stantly varying polarization state.          (Fig. 1)

To said rotor, attached is an armature having a plurality of magnetic paired poles disposed at certain spaces along the outer circumference of the cylindrical rotor in such a way that one of each of the magnetic pole pairs appears in the outside gap and the other appears in the inside gap.      Provided is a commutation mechanism for so exciting said armature of said rotor that the outside magnetic poles of said rotor are the same polarity as that of the magnetic poles of the inside stator. The commutation mechanism, further, so excites the rotating armature that the magnetic poles of said armature disappear just before the magnetic poles of the outside and inside stators and that they appear again just after the magnetic poles of the outside and inside stators and that they appear again just after the magnetic poles, of said stators during the rotation. Since such a rotary electric machine has a large output torque, it can be used, fore example, as a source for generating the driving force of an electric vehicle.
