Abstract: A blood pump for assisting a heart is provided having a stator and a rotor.  The rotor is magnetically radially supported creating a suspension gap between the stator and the rotor. The rotor can be supported axially by a Lorentz force bearing and can be magnetically rotated. The stator can have a single or double volute pump chamber and the rotor can have an impeller portion for pumping blood. The rotor can have a center bore as a primary blood flowpath. The suspension gap can be a secondary blood flowpath. The blood pump can also have an axial position controller and a flow rate controller. The axial position controller can cause the axial bearing to adjust the position of the rotor. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A method of operating the flow rate controller to create a pulsatile flow rate is also provided. Additionally, the blood pump can be part of a cardiac assist and arrhythmia control system. Moreover, a method of operating the flow rate controller can be provided which reduces the amount of energy needed to treat fibrillation. The method can include operating the flow rate controller to reduce a radial dimension of the ventricle prior to delivering defibrillation energy such that the ventricle contains less blood which absorbs less energy so that a larger fraction of the energy is delivered to the heart.

Abstract: There is provided exciter apparatus having a cast housing (11) and mounting base (14) secured to mounts bolted to the side plates of screening apparatus.  A pair of shafts are mounted for rotation in and extend out of both sides of the cast housing (11). A gear assembly is keyed to each shaft to form a gear train coupling the shafts. The outer ends of each of the shafts are provided with eccentric masses (30) aligned on their respective shafts 180~ out of phase. Drive spools (35) are driven by electric motors (not shown). Coupling spools (37) are adapted to accept flexible couplings for joining exciter units together. The gears (26) comprise 9 teeth of an 18-tooth module at 325.0 mm pitch circle diameter (PCD) and 65 mm axial dimension. The lands between the teeth are at a notional diameter 262.6 mm, the teeth having a corresponding notional tooth height of 31.2 mm to the PCD. The gear tooth chordal length at 34 mm is oversize for the module and the gear tooth involute surface extends past the gear tooth addendum to meet a 6.5 mm radius tooth tip. This configuration gives a lash of 9~, which enables the direction of excitation to shift to track the centre of gravity of the screen machine in use.

Granted: 2013-06-25
Abstract: The apparatus includes a pump for circulating pressurized fluid in a wellbore.    A control device controls the pump which a conduit interconnects to the wellbore. A downhole transducer detects changes in fluid pressure at a downhole location and generates signals accordingly. A processor generates actuator commands based on the signals. Actuators activate a downhole tool based on the actuator command. A modulating valve modulates the fluid pressure. A remote transducer detects the pressure remotely from the downhole transducer. The control device causes the pump to generate acoustic signals in the fluid via wave forms which the downhole transducer detects. The modulating valve generates wave forms in the fluid. The control device sends control signals via the fluid to the downhole transducer. Consequently the processor actuates the tools. Following correct actuation the modulating valve generates signals via pressure changes which the remote transducer receives to indicate successful tool deployment.

Abstract: The present invention relates to terrain navigation wherein an earth-reflected satellite signal is received from at least one reference signal source whose position is known (120), for example a navigation satellite. Based on information contained in the received signal a measured estimate of a shortest reflection distance (d1(t b)) to the satellite (120) is derived. A relative spatial movement (.DELTA.x, .DELTA.y, .DELTA.h) of a relevant craft (110) since a previous positioning instance (t a) is registered onboard the craft (110). Moreover, stored surface information is retrieved pertaining to an elevation (h1b) of the earth surface (130) in relation to the mean sea level (z0) at at least one geographical position (x1b, y1b). Based on the relative spatial movement (.DELTA.x, .DELTA.y, .DELTA.h) and the retrieved surface information at least one calculated estimate of the shortest reflection distance (d1(t b)) to the satellite (120) is derived. Finally, a geographical position (x1a, y1a, h1a) is determined on basis of the measured and calculated estimates of the shortest reflection distance (d1(t b)). Thus, a highly reliable and entirely passive positioning may be accomplished on basis of external signals from as few satellites (120) as one.

Title: Combustion method with integrated carbon dioxide separation by means of carbonation
Inventor: ABANADES GARCIA JUAN CARLOS
IPC: B01D53/34
Filed: 2003-03-14
Granted: 2011-05-17
Abstract: The invention relates to a method for separating CO2 from combustion gases, which can be used in large emissions sources (such as thermal power plants that use any type of carbonaceous fuel). The said method consists in bringing the combustion gases into contact with a calcareous sorbent (calcined limestone or dolomite) at 650-750°C, thereby producing a CO2 capture reaction by means of the rapid carbonation of the sorbent. The sorbent is regenerated in another reactor (calciner) producing a concentrated stream of CO2. This inventive method consists in arranging the combustion chamber in such a way as that the large heat demand in the calciner can be supplied from the said combustion chamber by a solid heat carrier circulating between the combustion chamber and the calciner or through metallic walls separating the combustion chamber and the calciner. To facilitate this heat transfer at the very high temperatures of the calciner, the calciner can be operated at low partial pressures of CO2. These low partial pressures can be achieved by feeding steam to the calciner or by applying a certain vacuum to the calciner.
