Patent CA-2251244-A1 (CA)
Title: Verifying hardware in its software context and vice-versa
Inventor: YENIGUN HUSNU
IPC: G06F11/36
Filed: 1998-10-21
Abstract: A method and apparatus that employs static partial order reduction and symbolic verification allow the design of a system that includes both hardware and software to be verified. The system is specified in a hardware-centric language and a software-centric language, as appropriate, and properties are verified one at a time. Each property is identified whether it is hardware-centric or software-centric. A hardware-centric property that contains little software is does not employ the static partial order reduction. Software-centric properties, and hardware-centric properties that have substantial amounts of software do employ the static partial order reduction. Following partial order reduction, the software-centric language specifications are converted to synchronous form and combined with the hardware-centric specifications. The combined specification is applied to a symbolic verification tool, such as COSPAN, and the results are displayed.

Patent CA-2256619-A1 (CA)
Title: Process for converting gas to liquids
Inventor: BEER GARY L
IPC: C10G5/06
Filed: 1997-07-09
Abstract: A process for converting a hydrocarbon gas (e.g. natural gas) to syngas which, in turn, is converted into a liquid hydrocarbon product wherein a substantial amount of the heat generated in the process is recovered for use in generating steam needed in the process or for conversion into mechanical energy. Further, tail gas produced by the process is used to fuel the gas turbine which, in turn, is used to power the compressor needed for compressing the air used in the process. By using tail gas to fuel the gas turbine, less of the compressed combustion-air is needed to cool the combustion gases in the turbine and, instead, can be used to provide a portion of the process-air required in the process; thereby possibly saving up to 20 to 30 percent of the horsepower otherwise needed to compress the required volume of the process-air.

Title: Process for cleaning and disinfecting contact lenses
Inventor: CHOWHAN MASOOD
IPC: C11D1/12
Filed: 1994-08-24
Abstract: An improved process for removing protein deposits from contact lenses with a single solution is described.  The process utilizes the cleaning effect of a cleaning agent in combination with the solvent action of water and physical agitation of the lens (i.e., by means of rubbing) to achieve a degree of cleaning which is comparable to or better than prior processes which utilize surfactant-cleaners.  The cleaning agent is selected from polycarboxylates, polysulfonates and polyphosphates.  The preferred cleaning agent is citrate.  The process also offers greater convenience, relative to many prior systems for cleaning and disinfecting contact lenses, since the need to utilize additional products to clean the lenses is eliminated.

Patent CA-2261209-A1 (CA)
Inventor: BRUNO EMILIO R
IPC: G08B25/10
Filed: 1999-02-02
Abstract: The Electronic Community Surveillance Device is a device that that will operate in a network of similar devices connected via Radio Wave Frequency transmitters and receivers. An unlimited number of these devices can operate in any given community within Radio Frequency Range of other said devices, see figure seven, but at least two are needed within range of each other. In the event of an Emergency the activation of the emergency switch on the Electronic Community Surveillance Device or the activation of the remote activation unit would cause the initiating surveillance device to broadcast over radio frequency a specified computer programming that will initiate all other surveillance devices within Radio Frequency Range, see (Fig. 7). The same computer programming will sound emergency, flashing emergency light and display incoming information on the Liquid Crystal Display about the location of the emergency. The known and unknown individuals that are participating in the Electronic Community surveillance is to respond by 1) calling 911 and giving displayed information on liquid crystal display to emergency personnel, 2) respond by activating the respond switch, 3) Moreover, if address is known to either monitor the premises or lend assistance to the distressed location.     When a given number of responses; from participating community members, in the same computer program software via Radio wave frequency is reported to the initiating unit, the initiating unit will broadcast computer programming via Radio Frequency stating sufficient response and that will silence all alarms activated. The remote activator will be equipped with an adjustable code so that individuality will be possible. The Electronic Community Surveillance Device will also be equipped with an adjustable code and both remote and device have to be on the exact same code for the remote unit to function. See figure four and five.

Title: Porphyrin compounds as telomerase inhibitors
Inventor: WHEELHOUSE RICHARD T
IPC: C07D519/00
Filed: 1998-02-04
Abstract: The present invention has identified compounds with extended aromatic chromophores that bind the G-quadruplex formed by the folding of single-stranded human telomeric DNA. These compounds have been shown to be effective telomerase inhibitors and are contemplated to be useful in developing cancer treatments. A model of cationic porphyrin interaction with quadruplex DNA by intercalation has been established and in combination with structure activity relations has provided novel porphyrin compounds that exhibit discrimination between binding duplex and quadruplex DNA and show improved activity against telomerase.

Patent CA-2285899-A1 (CA)
Inventor: SCHIRMER MICHAEL
IPC: B66B9/08
Filed: 1999-10-13
Abstract: A scissor lift that achieves enhanced vertical travel of the deck for a given amount of horizontal travel of the legs. The enhanced vertical travel is achieved by overlapping the deck pivot point (i.e., the point at which a leg is pivotally connected to the deck) with the frame pivot point (i.e., the point at which a leg is pivotally connected to the frame) when the deck is in the fully lowered position. That is, the deck pivot point is lower than the frame pivot point when the deck is fully lowered. The pivot points can occur on the same leg or on different legs. The deck and frame pivot points can provide purely pivotal movement or a combination of pivotal and some other type of movement (e.g., translational movement). The above-described scissor lifts can be utilized to perform corresponding methods of lowering a scissor lift. In the method, the deck pivot is positioned lower than the frame pivot when the deck is in the fully lowered position.

Abstract: A dispersion device for a dispenser for sprinkling liquid onto substance and/or heat exchange systems, in particular stacked or built-in elements arranged in columns or towers, has a central element (11) that can be inserted into an outlet (2) of a liquid dispenser (1). The area of the wall (11a) of the central element (11) which projects into the inner space (1') of the liquid dispenser (1) when the central element (11) is inserted therein has several inlets (25) through which the liquid (F) contained in the liquid dispenser (1; 100) can enter the inner space (12) of the central element (11) without being pressed into said space. According to the invention, the central element (11) is cylindrical and one or more outflow elements (15a-15d) are arranged in the inner space (12) of the cylindrical central element (11) of the dispersion device (10). The outflow elements (15a-15d) have each a top channel section (18a-18d) and a bottom dripping zone (19a-19d). The top channel sections (18a-18d) of the outflow elements (15a-15d) subdivide the inner space (12) of the cylindrical central element (11) of the dispersion device (10) into a corresponding number of outflow channels (16a-16d) which can be entered by the liquid (F) through the inlets (25) arranged in the wall (11a) of the central element (11). The bottom dripping zones (19a-19d) of the outflow elements (15a-15d) which project out of the central element (11) form finger-shaped elements (17a-17d) which point away from the longitudinal axis of the central element (11). The liquid (F) from the liquid dispenser (1; 100) which enters the outflow channels (16a-16d) of the central element (11) through the inlets (25) of the central element (11) of the dispersion device (10) can drip from the finger-shaped elements (17a-17d) onto the substance and/or heat exchange system.
