Patent CA-2202814-C (CA)
Inventor: FITZ PHILIP JOHN
IPC: H02M7/217
Filed: 1997-04-16
Granted: 2006-06-13
Abstract: A control arrangement for a multilevel convertor employs an AC reference signal which is locked to the AC system frequency and is compared with a number of DC threshold levels. Intersections of the reference signal and threshold levels triggers the firing and turning-off of GTOs within the convertor to produce the desired multilevel voltage output. Normal changes in system voltage, for example, are compensated by variation of the phase relationship of the reference signal with respect to the system voltage, and/or of the voltage values of the threshold levels. Sudden and drastic changes, especially reductions, in system voltage level are sensed and used to alter the amplitude of the reference signal so as to reduce the difference between the convertor multilevel voltage and the system voltage, thereby reducing the stress on the GTOs during faults.

Title: Torch valve assembly
Inventor: FARNHAM GILBERT ROLAND
IPC: F16K41/04
Filed: 1997-07-09
Granted: 2005-02-22
Abstract: A torch valve for pressurized fuel includes a valve body having a central, axial bore and a valve needle threadedly mounted in the bore for selectable axial positioning in the bore. A inlet portion of the bore forms an inlet connectable to a source of pressurized fuel. A second portion of the bore carries the valve needle. An outlet passage communicates with the bore at a point approximately where the second portion joins the first portion. The outlet passage extends laterally from the bore to open at an outlet orifice on the outer surface of the valve body. The outlet orifice includes means for attaching a torch and igniter assembly to the valve body. The needle includes a stem that terminates in a needle tip. An annular ridge extends from the stem spaced from the tip and defines a first groove between the ridge and stem. A second groove is formed in the stem spaced from the first groove. Each of the first and second grooves carries a resilient sealing ring. The second groove and ring seal the outlet passage from the ambient environment. By positioning the needle valve with the first groove and ring between the outlet passage and the inlet, the outlet is closed from the inlet. A spring and pin arrangement is coupled with the needle on the inlet side of the valve body to regulate the pressure of gas in the outlet passage.

Title: Method and arrangement for determining the position of a mobile radio terminal
Inventor: EKMAN BO KENNETH
IPC: G01S5/10
Filed: 1997-02-12
Granted: 2005-05-24
Abstract: The present invention teaches a method, system, terminals and service node for geographically positioning a first mobile radio terminal within a radio network comprising unsynchronised radio base stations by using a plurality of second fixed radio terminals whereby the positions of the radio base stations and the second fixed radio terminals are known. First and second radio terminals measure the relative receive times between the timing signals downlink received from at least three radio base stations and the second fixed radio terminals send them to a service node in the network using them for calculating the transmission time offsets of the timing signals downlink. Calculating the position of the first mobile radio terminal is performed either in the service node in the network or in the terminal itself, after respectively sending relative receive time measurements from the first mobile radio terminal to the service node, or broadcasting transmission time offset values and known positions from the service node to the first radio terminal to be positioned.

Abstract: Pattern data-like illustrations is stored in a ROM (24) in a printer (200).  This pattern data is sent via a communication cable (30) to a digital camera (100) from the printer (200). In the digital camera (300), image data representing a still picture stored in a compressed form in an image memory (9) and pattern data sent from the printer (200) are both expanded by a compressing/expanding section (8) after which they are synthesized with each other, and an image corresponding to the synthesized data is displayed on a color LCD (19). This synthesized data is compressed by the compressing/expanding section (8), and is then sent to the printer (200) from the digital camera (100) via the communication cable (30). The printer (200) expands the compressed synthesized data and then activates a color printer section (26) to print an image corresponding to the expanded synthesized data on a recording sheet.

Abstract: Polyethylene film having a combination of a high melt strength and a high dart impact strength is prepared from a linear low density polyethylene resin having a melt index, ("I2"), of from 0.4 to 1.5 g/10 minutes, a broad molecular weight distribution (of from 3.5 to 7) and a quasi homogeneous comonomer distribution (as evidenced by a copolymer/homopolymer ratio of from 3 to 19). The polyethylene resin is prepared in a dual reactor polymerization process. The film is especially useful for industrial and "heavy duty" packaging applications such as the manufacture of plastic packages used to contain goods for the construction, gardening and agricultural businesses. Examples of such goods include peat moss, fertilizer, soil, sand, salt, fiberglass insulation and crushed stone. The film has improved strength properties which are typically associated with those made from homogeneous (or "metallocene") polyethylene resins, yet also retains a stiff plastic "feel" which is not present in many metallocene resins. Most importantly, the plastic film of this invention may be produced at very high line speeds (i.e. improved production rates/efficiencies) in comparison to films made from prior art resins.

Abstract: An integer Z101 is divided by an integer I102 to obtain a remainder  R109. The integer I102 includes a polynomial of power of a basic operational unit of a computer. In this way, the integer I for divisor is limited based on the basic operational unit of the computer, thus a shift operation, which is required for a conventional operation method, can be eliminated. The remainder can be calculated by only addition and subtraction. Accordingly, a code size becomes compact and the remainder of the integer can be calculated at a high speed.
