Abstract: METHOD FOR THERMAL STIMULATION OF A SUBTERRANEAN RESERVOIR               AND APPARATUS THEREFOR     (D#78,828-F) ABSTRACT     A system and the equipment for economically enhancing recovery of hydrocarbon fluids from a subterranean reservoir in which a plurality of production and injection wells are formed. High grade steam from a common source is mixed with relatively cold water at each injection well to be treated.  To avoid, or substantially  reduce  condensation  shock  in  the  water/steam mixer, the high velocity cold water is initially heated in a steam compartment with minimal contact between the two fluids. Thereafter, the steam and the water are introduced to a heat exchange chamber in which the temperature of the water is raised prior to the two streams being merged for injection into a well as either heated water or as low quality steam.

Title: Apparatus and method for transfer and slurrying or dissolving hydratable dry bulk chemicals
Inventor: KEMP ROBERT A
IPC: B01F15/02
Filed: 1988-12-02
Granted: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for the transfer of a dry chemical is formed having a sealed solvation hopper positioned between a liquid driven eductor and a fitting for connection to a storage container, e.g. a railcar.  At the inlet end of the solvation hopper is a chemical inlet pipe which connects the interior to the exterior of the hopper.  Surrounding the chemical inlet pipe are a plurality of nozzles for the introduction of solvation liquid into the hopper.  The nozzles are disposed such that the solvation liquid washes the interior surface of the hopper to prevent plugging by hydrates (solvates) which may be formed.  At the outlet end of the hopper, the hopper is connected to the suction opening of a liquid eductor.  In use, the exterior end of the chemi-cal inlet pipe is connected to the dry chemical storage container.  Liquid flowing through the liquid eductor creates a suction and draws dry chemical out of the storage container and into the hopper.  In the hopper, solvation liquid is supplied through the nozzles to wet the dry chemical and to wash the surfaces of the hopper, pushing the wetted material toward the outlet end of the hopper.  At the outlet end of the hopper, the wetted material is sucked out into the eductor where it is combined with the flow of eductor liquid.          The material leaving the eductor is recovered and sent either to storage or directly for processing.

Abstract: An activity entry apparatus for making activity entries onto pre-established time log activity forms is disclosed. The apparatus comprises a time log form overlay sheet of resilient and significantly transparent material having a series of writing instrument guides extending therethrough. The guides define a series of activity change segments having lengths at least great enough to extend from one time log form activity section to a directly adjacent time log form activity section. At least one such activity change segment has a length great enough to extend from and between activity sections on the time log form which are separated furthest from one another. The guides also define time interval segments which extend from the activity change segments. The time interval segments have lengths which are equal to predetermined distances between log form time indicator lines which represent selected intervals of time during the pre-established time period for a given activity on the time log form. The apparatus assists a timekeeper in quickly, easily and accurately logging time on particular pre-established forms.

Title: Infusion stent system
Inventor: GREGORY FRANKLIN P
IPC: A61F2/82
Filed: 1989-06-28
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE       The infusion stent system includes a stent member having a plurality of openings provided in the wall of the stent along the entire length of the stent.  An imperforate open ended guide tube member used for installation and infusion of the stent accommodates a core member that stiffens the guide tube member.  The core member is relatively moveable in the guide tube member to provide selective flexibility at a proximal end of the guide tube member.  The stent is position in the renal cavity, the ureter and bladder by being pushed along the guide tube member by a push catheter. Fluid is infused through a proximal end of the guide tube member when the core member is removed.  The proximal end of the guide tube member can be located at any selected position within the stent.  Thus fluid can be infused to any selected location in the stent by positioning the proximal end of the guide tube member at a desired location in the stent.  Openings in the stent that are bypassed by the guide tube member are not infused with fluid.

Granted: 1997-01-28
Abstract: A multiple set point material condition monitoring system is disclosed which is responsive both to the level of material with respect to a sensor and the extent of material coating which has accumulated on the sensor.  The system provides an output when a predetermined coating thickness has been exceeded, so that the sensor may be cleaned before the coating can accumulate to the extent where a false level output is generated.  The disclosed systems include three electrode guarded sensors, a bridge comparing the sensor output with a reference, and a bridge reference which is automatically and repeatedly caused to assume a sequence of values corresponding to material condition set points, one of which causes an output when a predetermined coating thickness has occurred and another of which generates a level output.  In one embodiment, separate outputs are provided corresponding to each set point.  In another embodiment, a single tri-state output is responsive to both set points.
