The instant invention relates to a reactor useful in upgrading heavy oils admixed with a catalyst composition in a slurry. The liquid recirculating reactor of this invention employs a dispersed bubble flow regime, which requires a high liquid to gas ratio. A dispersed bubble flow regime results in more even flow patterns, increasing the amount of liquid that can be upgraded in a single reactor.

In a first intense suction, a supply line K is subjected to suction by a suction pump 23 with a portion of the supply line K held in a blocked state. Subsequently, the blocked portion of the supply line K is opened and trapped bubbles are discharged from a pressure chamber 46, which is located relatively upstream. In a subsequent second intense suction, the suction by the suction pump 23 is performed on the supply line K with a portion of the supply line K held in a blocked state, until a maximum negative pressure smaller than a maximum negative pressure of the first intense suction is obtained. The blocked portion of the supply line K is then opened, thus discharging trapped bubbles from an upper filter chamber 64, which is located relatively downstream.

A filtering apparatus comprising an elongate container body, an inlet, an inlet reservoir, an outlet, an outlet reservoir, and at least two filter elements, wherein each filter units contains two or more space-apart and co-axially stacked filter elements encased in a cylindrical-shaped filter cartridge. Contaminated fluid flows from the inlet, through the perforations located on the inlet reservoir separator, and into the elongate container body. Fluid flows into the filter units through perforations in the filter cartridge and the open ends of the filter cartridge. The filter units use an opposed axial flow method to draw the fluid through the filter elements. The filtered fluid flows through a perforation in the axial conduit, passes through the axial conduit outlet into the outlet reservoir. The filtered fluid then exits through the outlet. The present invention may be used in operation with a motor and pump to filter large flow rates and volumes of contaminated fluid.

The at least one sidewall may have an integrally formed liquid passageway therein having an upper opening coupled in fluid communication with the spray head tube, and may have a lower liquid pick-up opening adjacent the base.

The invention provides a pump which has reduced pressure loss by using fewer mechanical on-off valves, which has increased reliability, which can be used under a high load pressure, which can be driven at a high frequency, and which has good drive efficiency by increasing discharge fluid volume per pumping period. A circular diaphragm, disposed at the bottom portion of a case, has its outer peripheral edge secured to and supported by the case. A piezoelectric device to move the diaphragm is disposed at the bottom surface of the diaphragm. A space between the diaphragm and the top wall of the case is a pump chamber. An inlet flow path, having a check valve serving as a fluid resistor disposed thereat, and an outlet flow path, which opens to the pump chamber during operation of the pump, open towards the pump chamber. In the pump, driving of the piezoelectric device is controlled so that an average displacement velocity in a pump chamber volume reducing step of the diaphragm becomes a velocity at which the diaphragm reaches the reached-displacement-position in a time equal to or less than ½ and equal to or greater than 1/10 of a natural vibration period T of fluid inside the pump chamber and the outlet flow path.

Apparatus for transferring visible images from a first surface to a second surface and/or for fusing or fixing a visible image to a substrate, comprising: a cylindrical member secured between two round end plates to form a cylindrical structure; a volatile liquid incorporated within the cylindrical structure in a cavity, at least one wall of which is thermally connected to the cylindrical member; and a heater that heats the liquid to an operating temperature, wherein the amount of the volatile liquid is such that all of the volatile liquid would be evaporated at a temperature that is less than about 20° C. above the operating temperature.

A heat pipe includes a reservoir of liquid that is connected to a horizontal portion of the heat pipe via a capillary connection. The heat pipe includes a temperature sensor in proximity to a heat interface in the horizontal portion and a controller that controls a heater for the reservoir. As power into the heat pipe increases, the controller turns on the heater, causing the temperature of the liquid in the reservoir to rise. Liquid then passes from the reservoir through the capillary connection into the horizontal portion, thereby dynamically increasing the amount of liquid in the heat pipe, which increases performance of the heat pipe at higher power levels. When the heater is off, as the heat pipe cools, the liquid condenses and flows back through the capillary connection into the reservoir. The result is a heat pipe that provides demand-based charging of the liquid based on power level.

A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. In additional aspects, at least one primary layer region can have a non-uniform, selectively zoned basis weight distribution. Particular configurations of the at least one primary layer region can be constructed with a target area of the primary layer region having a basis weight which is less than a basis weight of another non-target portion of the primary layer region.
