Patent CA-2394761-C (CA)
Title: Step wave power converter
Inventor: DROPPO GERALD W
IPC: H02M7/49
Filed: 2000-09-28
Granted: 2009-06-02
Abstract: A single- or multi-phase step wave power converter includes multiple transformers configured to receive DC voltage from one or more power sources. Each of the transformers includes a primary winding and a secondary winding. The transformers are each configured to supply a step for a step wave AC output. Bridge circuits are supplied for controlling input of DC voltage into the primary windings of the transformers. Steps for the step wave AC output are output from the secondary windings based upon the input provided to the primary windings. DC source management circuitry manages which DC power source(s) supplies DC voltage input to each of the bridge circuits. The management circuitry provides seamless power switching between the plurality of DC power sources based on each power source's performance characteristics. A  pulse-width modulator can also be provided to the step wave power converter to modulate the input into a selected primary winding. In this way, the step wave AC output can be fine-tuned in substantial conformance with an ideal AC waveform.

Abstract: The invention relates to microemulsion compositions containing water, a mixture of nonionic surfactants, and oil.  The microemulsion provides for the removal of hydrophobic particularly oily soils from a variety of substrates. The compositions can be used for hard surface, laundry cleaning, hand washing, and car washing.  Typical hydrophobic soils are oily based soils derived from petroleum oils or natural fats and oils also containing a significant proportion of particulate soils such as carbon, common dirt and other non-water soluble typically hydrophobic soil particulate. The microemulsion composition can include a splitting agent such as an amphoteric surfactant for controlling the conditions under which the microemulsion will split.

Abstract: The invention provides a pump and motor assembly (10) connected to a reservoir (24). The pump can be used for the purpose of supplying fluid to a double acting hydraulic cylinder the ends of which are connected to two connection ports (1, 2) provided on the pump housing (11). The pumping mechanism includes one single acting piston (5) that reciprocates and rotates simultaneously on the piston axis with the reciprocating piston motion imported by a single row ball bearing (13) mounted on the piston (5) and inclined at an angle to the piston axis and having a single point on the outer race of the single row ball bearing (13) restrained. The pump includes two one way check valves (25, 26 and 27, 28) in passages between the reservoir and the connection ports that allow fluid to be drawn into the pumping chamber when the attached cylinder is expanding. A bleed valve, constructed using two balls (30, 31), allows fluid displaced by the rod of a double acting cylinder to be returned through a third passage to the reservoir when the attached cylinder is retracting.

Abstract: A device for a paper-making installation has at least one wire belt, which installation has supporting or scraping elements of ceramic material spaced from one another in the direction of movement of the wire belt for supporting the wire belt or scraping off the water emerging from the paper pulp or paper strip located on the wire belt and passing through it. The wire belt comes to rest on the upper sides of these elements. In the invention, there is a load-bearing frame which corresponds in width to the width of the wire belt. The frame has load-bearing strips, on which supporting or scraping elements are fixed. These elements are located spacedly next to one another. The spaces between the supporting or scraping elements form passage channels for the water emerging from the paper pulp or paper strip or for the air sucked through the wire belt. This arrangement provides adequate support for the wire belt while allowing very effective application of vacuum to the wire belt.

Title: Increasing data throughput in optical fiber transmission systems
Inventor: VRAZEL MICHAEL G
IPC: H04L1/00
Filed: 2001-12-21
Granted: 2011-10-25
Abstract: Data throughput rates are increased in an optical communication system (500) without requiring replacement of the existing optical fiber in a link. Channel throughput is increased by upgrading the components and circuitry in the head and terminal of an optical communication system link (500). The increase in system throughput is achieved by using advanced modulation techniques (502) to encode greater amounts of data into the transmitted spectrum of a channel, thereby increasing the spectral efficiency of each channel. This novel method of increasing transmission capacity by upgrading the head and terminal of the system to achieve greater spectral efficiency and hence throughput, alleviates the need to replace existing fiber plants. Spectrally efficient complex modulation techniques (502) can be supported by interface circuits with an increased level of signal processing capability in order to both encode multiple bits into a transmitted symbol and decode the original data from the received symbol.

Abstract: La présente invention a pour objet des sources de rayons X pour la mammographie. Une source de rayons X à microfocalisation de petite dimension (30µm et moins) ayant un spectre X optimisé pour une mammographie améliorée est obtenue grâce à une méthode et à un système de la présente invention. La source proposée de rayons X est basée sur l'utilisation de plasmas créés par la distribution énergétique d'électrons suprathermiques produits pendant l'interaction du faisceau laser avec une cible solide. Ces électrons chauds pénètrent la couche superficielle de plasma froid et interagissent avec le noyau solide de la cible. La méthode et le système de la présente invention permettent d'optimiser la taille de la source de rayons X, sa distribution spectrale et son efficacité de conversion dans la gamme 17,3 - 28,5 keV (adapté à l'épaisseur des tissus mammaires).

Filed: 2003-10-09
Granted: 2007-06-05
Abstract: The present invention generally relates to a cutting insert for use with wellbore milling tools. The cutting insert forms an angle between a milling surface of the insert and a surface of the tool that the insert is attached to in order to provide the proper cutting incline, and substantially perpendicular sides of the insert relative to the milling surface of the insert provide continuous support for the milling surface. In addition, the inserts can comprise spacers and legs that evenly distribute bonds formed between inserts and bonds formed between the inserts and the surface of the tool, respectively. Selecting the dimensions of the spacers and legs alters the strength of the bonds.

Abstract: An apparatus for filling a screw (7) bearingly supported within a housing (6), in particular of an extruder, for processing of pre-comminuted synthetic plastics material, in particular PET, has a filling opening (5) for the screw housing (6). This filling opening (5) is in flow connection with the lower outflow opening (4) of an upright receptacle 81) for the material to be processed. Within the receptacle (1), tools (30, 31) circulate around a, preferably vertical, axis, which tool act onto the material positioned within the receptacle (1). This material is introduced into the evacuable receptacle (1) through a sluice (60). A  quickly circulating tool (30) for creating a mixing cone (71) is disposed between an upper interior portion (68) and a lower interior portion (69) of the receptacle (1).  Within the lower interior portion (69) that constitutes a dwell space for the heated plastics material that has reached it for thermal homogenization thereof, also circulating tools (31) are disposed, which, however, are mere mixing tools without substantial introduction of power, so that within this dwell space an agglomeration of the plastics material is avoided.

Abstract: A photo-catalytic overcoat on a UV reflective paint layer is employed to maintain high reflectance for long periods of time by continuously removing organic films when exposed to UV light. Advantageously, nano-particles comprising the photo-catalytic overcoat are composed of a semiconductor material that lead to the production of oxygen and hydroxyl free radicals when illuminated with UV light in the presence of water vapor. Some of these free radicals oxidize organic surface films, converting the surface films into gaseous H2O and CO2. This reduces the amount of organic deposits on the surface of the reflective paint layer.
