Patent CA-2008393-A1 (CA)
IPC: E21B43/29
Filed: 1990-01-23
Abstract: A hydraulic borehole mining system has a cutting jet nozzle supported on an insert short length of tubing of a cutting jet head within a water supply conduit in the lowest section of a multi-conduit pipe string that extends from the surface through a borehole to a target zone to be mined.  A rod extending from the surface through the string outside of the water supply conduit connects to the head to reposition the nozzle vertically, independent of movement of the conduit or string.  The borehole annulus is sealed and connected to a surface standpipe for development of a hydrostatic head pressure that acts, with or without downhole pump assistance, to raise the slurry created by the nozzle jet up through a second conduit in the pipe string.  Material is pumped down the same second conduit after mining to backfill the hole.

This may be effected, e.g. by coating an emulsion and drying down appropriately.
Patent CA-2009980-A1 (CA)
Inventor: WAFFORD LAWRENCE
IPC: B65H15/00
Filed: 1990-02-14
Abstract: An apparatus is disclosed for flipping over flexible and limp planar workpieces such as fabric. The apparatus includes a primary workpiece propeller having a cylindrical means for contacting the workpiece about a central rotating axis.  A slot of sufficient size to receive the workpiece is positioned in a vertical orientation beneath the primary propeller. The slot preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller.  The fabric is drawn into the slot by the rotation of the propeller and follows the contour of the flared open end of the slot .  The fabric enters into the slot until the trailing edge of the fabric is in contact with the primary propeller.  The trailing edge of the fabric is gripped by the propeller and thereby drawn to the opposite side of the flared opening of the slot and is subsequently pulled out of the slot.  The fabric has thereby been inverted so that the top of the fabric is now on the bottom.

Title: Extraction system with a pump having an elastic rebound inner tube
Inventor: WELLS SAMUEL L
IPC: F04B47/08
Filed: 1990-02-28
Abstract: EXTRACTION SYSTEM WITH A PUMP HAYING      AN ELASTIC REBOUND INNER TUBE`            Abstract of the Disclosure An elastic rebound pump comprises a flexible inner tube having a substantial elastic rebound surrounded a by pump housing. The inner tube defines an inner chamber and the pump housing forms an outer chamber for confining a pump fluid. The pump allows pressurized gas or hydraulic fluid into the outer chamber to collapse the inner tube thereby discharging liquid from the inner chamber through an outlet opening. The pump alternatively releases the pressurized fluid from the outer chamber thereby allowing the inner tube to rebound to a full configuration and draw liquid into the inner chamber through the inlet opening. By repeatedly allowing pump fluid into the outer chamber and sequentially releasing the pump fluid from the outer chamber, the pump produces a substantially steady flow of liquid.  An extraction pump system includes the elastic rebound pump for removing liquid hydrocarbons from ground  water collected in a well. The elastic rebound pump fits easily into small diameter wells and can be suspended above the liquid hydrocarbons in the well. An alternative extraction pump system includes a submersible pneumatic pump positioned within the ground water in the well for creating a cone of depression, and the elastic rebound pump and the submersible pump are driven simultaneously.  In another disclosed extraction pump system, the elastic rebound pump is suspended within the housing of the submerged pneumatic pump.  In still another disclosed extraction pump system, the elastic rebound pump is driven with pressurized ground water from a submersible pump.

Inventor: LATTO BRIAN
IPC: B01F33/40
Filed: 1990-03-30
Abstract: A method and apparatus is disclosed for mixing or agitating fluids using vortex rings in which a tube of inside diameter d is inserted into the fluid with an open end in the fluid. Fluid is drawn into the tube, and a slug of fluid is propelled a distance L down and out of the tube to create a vortex ring at the exit of the tube for propagation through the fluid. The ratio of L/d is between 0.8 and 3.8. The propelling means preferably involves a pulser cylinder communicating with the tube and a piston positioned in the pulser cylinder for reciprocating motion towards and away from the fluid to be mixed or agitated, or a bellows serving a similar function. The propelling means provides a generally square wave pressure impulse to the fluid to eject it from the tube in the form of a vortex ring.

Abstract: A novel method is described for growing tall fescue sods on a solid base in large rolls.  Whole culm straw is  placed  1-2  inches  deep  over  the  solid  base, typically plastic  sheeting.    Thirty to  forty cubic yards of composted materials are then applied to the straw, filling the voids and interstices to produce a coherent matrix.  This is seeded with tall fescue, then irrigated,  fertilized,  and  mowed  in  a  conventional manner.    Unharvested wheat seed  left  in the  straw germinates  along with the  tall  fescue  and  forms a vigorous primary rooting system which rapidly effects a bona  fide  sod  about  one-half  inch  thick  and approximately one-half the weight of a conventional mineral sod.   The synthetic sod is harvested in large rolls,  typically  as  much  as  five  feet  wide  and comprising 20-50 square yards.   These big rolls are laid at the installation site by the grading tractor, obviating the need for a fork lift, pallets, and laying crew, as used in conventional sodding.
