Patent CA-2717897-A1 (CA)
Inventor: KOWOLL JOHANNES
IPC: C10J3/72
Filed: 2009-02-27
Abstract: With a method and a device for treatment of fluid streams that occur in the gasification of fuels that contain carbon and ash, it is supposed to be possible to optimally use the heat contents contained in the system, as well as the amounts of water required for cooling and condensation, with recirculation of the latter.     This is achieved, with a method according to the invention, in that the suspension passed out of the mixing container is relaxed in at least one subsequent stage, with evaporation of at least part of the water, and a reduction in temperature, and that the resulting steam is cooled by means of direct contact with water, and at least partly condensed out, whereby the device according to the invention is particularly characterized in that a line (6) is provided between the lower region of the mixing container (1b), to a first relaxation container configured as a washing column (7a), whereby the washing column is provided with a condensate collection bottom (8a) and a recirculation line (10a) to the mixing container (1b), equipped with spray heads, for the resulting condensate.
Patent CA-2718168-A1 (CA)
Inventor: MANOR DROR
IPC: H02M1/14
Filed: 2009-03-10
Abstract: A power supply for converting AC to a regulated DC output current, utilizing two serial switched mode power supplies, the first providing an intermediate DC output voltage with only moderate ripple properties, this output being input to the second, which operates as a DC/DC converter to provide the desired output with low ripple and good regulation. The diode rectifier assembly has no reservoir/smoothing capacitor, or one of much smaller capacitance than in prior art power supplies. The large resulting rectifier output ripple is overcome by use of the two power supply units, at least the first having a smoothing capacitor at its output. A majority of the energy stored in this capacitor is utilized during each AC half cycle. Such power supplies also provide improved hold-up times. The power supply is also constructed to have low standby power consumption, by use of a double burst configuration.

Abstract: Disclosed are soil additives comprised of self-situating, stimuli-responsive polymer compositions and methods of their use. In one embodiment, the polymer composition or polymer network comprises permanent cross-links and non-permanent cross-links, wherein the non-permanent cross-links are capable of being removed upon application or exposure to a stimulus, typically located within the soil. In another embodiment, the method of increasing water retention in soils includes applying a soil additive, comprising polymer networks of the present invention admixed with an aqueous solution to form a colloidal dispersion solution or suspension, to a soil surface. The suspension or colloidal dispersion solution facilitates penetration of the polymer composition through the soil surface and into the soil, migrating typically to lower water potential areas and, more typically, along drainage channels located within the soil. After penetration of the soil surface, the polymer network is then exposed to a stimulus, typically present in the soil, whereby the non-permanent cross-links are removed and the polymer composition undergoes a volumetric change. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.

Abstract: Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.

IPC: A61K9/51
Filed: 2004-06-28
Abstract: The invention describes a new class of crystalline silica material having two levels or porosity and structural order. At the first level, building units are nanoslabs of uniform size having zeolite framework. At the second structural level, nanoslabs are assembled, e.g. linked through their corners, edges or faces following patterns imposed by interaction with cationic surfactant or triblock copolymer molecules. After evacuation of these molecules, microporosity is obtained inside the nanoslabs, and a precise mesoporosity between the nanoslabs depending on the tiling pattern of the zeolite nanoslabs, as evidenced by X-ray diffraction. These materials are useful for the fixation of biologically active species, such as poorly soluble drugs.

Title: A support device for the establishment of a controlled flow of blood in a body part
Inventor: DAHL FLEMMING
IPC: A47C23/00
Filed: 2009-08-18
Abstract: To achieve a support for sitting or lying individuals who have difficulty in moving, the problems associated with this, such as decubitus, may be remedied by a support device according to the invention, in which a large number of cylinders (4) are arranged, each having a piston and a piston rod of its own which carries a pressure plate (3). When liquid is discharged and liquid is simultaneously supplied to an adjacent cylinder (4), the blood (9) will flow directly from the one pressure plate (B) to the adjacent pressure plate (A) and is thereby conveyed through the shortest possible path in the body (8). This pattern is repeated for all the pressure plates, and this provides an unprecedentedly effective flow of blood to remedy the distress which is associated with a more or less permanent sitting or lying posture.

Abstract: A method for a base station to obtain radio capability information of a User Equipment (UE) in long term evolution system comprises that: a mobility management entity sends an initial context setup request message to the base station, and the base station determines whether the received initial context setup request message contains an Information Element (IE) of forbidden inter radio access technologies; when contains, the base station writes the radio access technology types which are not included in the IE of forbidden inter radio access technologies into a query message, and sends the query message to the UE; otherwise, the base station writes all radio access technologies supported by protocol into a query message and sends the query message to the UE; after receiving the query message, the UE sends the UE radio capability information of radio access technologies supported by the UE itself to the base station.  The above method avoids the blindness of writing query message for the base station, which reduces the overhead of the air interface, thereby shortens the connection delay of the UE in the long term evolution system.
