Title: Fluid pumping apparatus

Abstract

A method and apparatus suitable for coupling seismic or other downhole sensors to a borehole wall in high temperature and pressure environments. In one embodiment, one or more metal bellows mounted to a sensor module are inflated to clamp the sensor module within the borehole and couple an associated seismic sensor to a borehole wall. Once the sensing operation is complete, the bellows are deflated and the sensor module is unclamped by deflation of the metal bellows. In a further embodiment, a magnetic drive pump in a pump module is used to supply fluid pressure for inflating the metal bellows using borehole fluid or fluid from a reservoir. The pump includes a magnetic drive motor configured with a rotor assembly to be exposed to borehole fluid pressure including a rotatable armature for driving an impeller and an associated coil under control of electronics isolated from borehole pressure.

  • A relatively small, mobile system for mixing and pumping slurry explosives includes a vehicle and demountable unitized equipment for metering, mixing, and pumping to a point of use, a slurry of liquid and nondissolved solid particulate ingredients. The product is a suspension of particles in a liquid medium of viscous gel form. The apparatus includes multiple supply sources and feeders for particulate ingredients and a pump for liquid, all emptying into a mixing zone, the individual feeders being driven at selectively or variably controlled rates. Operation of the feeder elements may be mechanical or by fluid pressure. The desired volumemore » of liquid is adjustable, being metered by mechanical pump and/or timer means; product slurry delivery is by a variable output pump. The system is designed to carry the separate ingredients safely to sites often inaccessible to prior art equipment, there to prepare the explosive slurry or gel on site and deliver it promptly to the point of use.

  • A method is described for improving the efficiency of an internal combustion engine having power and exhaust operational cycles at least one cylinder with intake and exhaust valve means and intake and exhaust conduit means comprising the steps of: creating a first positive sonic shock wave in the intake conduit means during the first one quarter of the exhaust cycle prior to the normal opening of the intake valve means according to a predetermined engine timing sequence; opening the intake valve means according to the predetermined engine timing sequence; creating a second sonic shock wave in the exhaust conduit meansmore » during the last one half of the power cycle prior to the opening of the exhaust valve means according to a predetermined engine timing sequence; and opening the exhaust valve means according to the predetermined engine timing sequence; the first sonic shock wave causes droplets of fuel collected in the intake conduit means to be atomized prior to the air and fuel mixture being pulled through the intake conduit into one of the at least one cylinder. A second negative sonic shock wave produced by the second sonic shock wave reaches the exhaust valve means during its normal predetermined opening, causing the gases of combustion to be aided in their removal from the cylinder into the exhaust conduit means.« less
  • A vibratory fluid pump having a force generator for generating asymmetric periodic waves or oscillations connected to one end of one or more fluid conveyance means, such as filaments. The opposite ends of the filaments are connected to springs. Fluid introduced onto the filaments will traverse along the filaments according to the magnitude of the positive and negative excursions of the periodic waves or oscillations, and can be recovered from the filaments.
  • A microfabricated device and method for proportioning and mixing biological or chemical materials by pressure- or vacuum-driven flow is disclosed. The microfabricated device mixes a plurality of materials in volumetric proportions controlled by the flow resistances of tributary reagent channels through which the materials are transported. The microchip includes two or more tributary reagent channels combining at one or more junctions to form one or more mixing channels. By varying the geometries of the channels (length, cross section, etc.), a plurality of reagent materials can be mixed at a junction such that the proportions of the reagent materials in themore » mixing channel depend on a ratio of the channel geometries and material properties. Such an approach facilitates flow division on the microchip without relying on techniques external to the microchip. Microchannel designs that provide the necessary flow division to accomplish valving operations using a minimum of pressure or vacuum sources are also described. In addition, microchannel designs that accomplish fluidic operation utilizing a minimal number of fluidic reservoirs are disclosed.« less
