20090252629 | PUMP AND PUMPING SYSTEM FOR MICROFLUIDIC LAB-ON-A-CHIP USING POROUS STRUCTURE AND FABRICATING METHOD THEREOF - The present invention relates to a pump and pumping system for a microfluidic lab-on-a-chip, and a fabricating method thereof. An exemplary embodiment of the present invention provides a method of fabricating a pump for microfluidic lab-on-a-chips, the method including: infiltrating PDMS (polydimethylsiloxane) solution into a porous lump of water-soluble material; performing soft baking of the porous lump of water-soluble material containing the PDMS solution; and dissolving the porous lump of water-soluble material via water to obtain a porous PDMS structure. | 10-08-2009 |
20090311118 | HOLDER DEVICE AND HIGH-PRESSURE PUMP HAVING THE SAME - A holder device has an elastic member and contact members. The elastic member is curved to extend approximately along a major arc of curvature and is elastically deformable to change a radius of curvature thereof. The contact members are circularly arranged along an inner circumferential side or an outer circumferential side of the elastic member so that each of the contact members is opposed to the elastic member in a radial direction of the elastic member. Each of the contact members has a sidewall that is opposed to the elastic member in the radial direction and is curved along an arc of curvature. A radius of curvature of the sidewall is shorter than the radius of curvature of the elastic member in its natural state. | 12-17-2009 |
20100178185 | FLUID INTAKE AND EXHAUST FITTINGS FOR A COMPRESSOR OR PUMP - We provide a compressor or vacuum pump fluid intake manifold having a fluid intake and a pair of ports provided by male and female fittings that are slidably engaged to one another. The male fitting has a portion which forms a hollow plug which fits within a respective fluid intake of the compressor housing. The plug portion, or plug, is integrally molded with a longitudinal section of the male fitting member. In similar fashion, the female fitting includes a plug portion which interfaces with a fluid intake in the compressor housing. The plug portion is integrally molded with a longitudinal portion of the female fitting. In one embodiment, each of the plugs includes three extending flanges forming an integral portion of the plug. Two of the three flanges are furtherest away from the plug. These two flanges provide a contact pressure seal with portions of the compressor housing that define the fluid intakes which receive the plugs. The other plug serves to prevent the plugs from slipping out of the fluid intakes during normal use of the fluid intake manifold. Further, instead, each of the plugs can have a raised insert surface defining a groove with an O-ring and a flange integral with and extending from a surface of the plug. The 0-ring provides a contact pressure seal with portions of the housing defining the compressor intake. The radially extending flange serves to inhibit the removal of the plug from the compressor intakes during normal use of the fluid manifold. | 07-15-2010 |
20100221132 | INLET FOR PUMP - An inlet for a pump is provided herein including a first elongated component and a tubular second elongated component disposed coaxially about the first elongated component so as to define a space therebetween. Advantageously, with the subject invention, an inlet for a pump can be provided which can be modularly formed from components. In this manner, the components can be manufactured, e.g., by molding, and assembled with a pump, thereby avoiding the difficulties associated with the manufacture and assembly of dip tubes. | 09-02-2010 |
20100254840 | MECHANICAL SEALING DEVICE, AND A PUMP - A mechanical sealing device and a pump including a mechanical sealing device are described. The sealing device includes a first seal element ( | 10-07-2010 |
20110103986 | COMBINED BEARING AND ROTARY MACHINE - A highly reliable combined bearing capable of achieving equal and sufficient lubrication of a plurality of rolling bearings with a simple and compact structure is provided. The combined bearing includes a first rolling bearing and a second rolling bearing which are in contact with each other and arranged on the same axis; and a lubricating-oil inlet for introducing a lubricating oil into an inner space formed between the first rolling bearing and the second rolling bearing, the lubricating-oil inlet being provided on at least one of an outer ring of the first rolling bearing and an outer ring of the second rolling bearing. | 05-05-2011 |
20110236239 | LIQUID CONTAINING APPARATUS - A liquid containing apparatus includes a first vessel for containing a main body of liquid and a second vessel, which is in fluid communication with, and located below, the first vessel. The second vessel has means for draining liquid therefrom and a vessel wall allowing the liquid within the vessel to be viewed. The liquid containing apparatus may be, for example, a support system for a mechanical seal in which a vessel contains a reservoir of a liquid, such as water, for providing a barrier or cooling fluid to the seal. | 09-29-2011 |
20110243773 | UNIVERSAL OIL FITTING - A universal oil fitting may include a body and an orifice. The body may include a first end, a second end, a first outer portion and a second outer portion. The first outer portion may include external threads and may extend longitudinally between the first end and the second outer portion. The orifice may extend longitudinally through the body and may include a first portion having a first inner diameter and a second portion having a threaded second inner diameter. The first portion may extend longitudinally between the first end of the outer body and the second portion. | 10-06-2011 |
20110262288 | WEAR PLATE KIT FOR BRASS WATER PUMP - A wear plate kit for a 496 style/Mercruiser(R) brass water pump includes: a first wear plate to be positioned between the base assembly and the rotor; a second wear plate to be positioned between the base assembly and the upper assembly; and a third wear plate to be positioned between the rotor and the upper assembly. The wear plates repair wear to the pump caused by the rotor. | 10-27-2011 |
20120076680 | MOUNTING AND DAMPING SYSTEM FOR A COMPRESSOR - A mounting and damping system for a compressor including a mounting lug removably coupled to at least a portion of a housing of the compressor and a damping member disposed therebetween. The mounting lug and the damping member include at least one aperture formed therein to receive a bushing therethrough, wherein an outer diameter of the bushing is substantially smaller than a diameter of the aperture formed in the mounting lug to militate against contact therebetween. | 03-29-2012 |
20140193282 | Drilling Fluid Pump Module Coupled to Specially Configured Riser Segment and Method for Coupling the Pump Module to the Riser - A pump module for a drilling riser includes at least one pump mounted to a frame, the frame including features to couple the frame to a segment of riser. A fluid inlet is affixed to the frame. The fluid inlet is in fluid communication with an intake of the at least one pump. The fluid inlet has features to make fluid tight hydraulic connection to a fluid outlet of the riser segment when the frame is coupled thereto. | 07-10-2014 |
