Patent CA-2086599-A1 (CA)
Inventor: TACKETT JAMES E JR
IPC: C09K8/512
Filed: 1991-07-02
Abstract: The present invention is a process for selectively plugging high permeability zones of a subterranean hydrocarbon-bearing formation by enhancing the delay associated with the in situ formation of a polymer gel. The process comprises predetermining a gelation delay time based on a formation's temperature, permeability and porosity, the distance from the well bore a region to be plugged is located, and a volumetric rate of gelation fluid injection. A gelation solution is then prepared comprising polyacryla-mide a polyvalent metal carboxylate crosslinking agent, a gelation delaying agent and a buffer with a pKa of about 3.5 to about 6.8. Gelation delays are achieved by selecting the polyacrylamide concentration, delaying agent concentration and type, and buf-fer concentration and type, for given formation conditions. Delay times can range from several hours to several weeks at forma-tion temperature near 176 °F (80 °C) and from several hours to about one day at formation temperature above about 219 °F (104 °C). The prepared solution is then injected into the formation via a well bore and allowed to gel. The gel selectively plugs high permeability zones within a subterranean hydrocarbon-bearing formation, at temperatures and distances from the well for-merly unobtainable, resulting in improved vertical or areal conformance of injected fluids and improved oil production.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a process for producing a particle-stabilized metal foam from a composite capable of acting as a precursor for the metal foam.  The composite is formed by heating a matrix metal, e.g. aluminum or an aluminum alloy, above its liquidus temperature to form a liquid matrix metal, adding to the liquid matrix metal stabilizer particles capable of remaining dispersed within the matrix metal while not being fully wetted by the liquid matrix metal, e.g. MgO particles, and mixing the liquid matrix metal and stabilizer particles under an atmosphere of a gas, e.g. air, in such a way that bubbles of the gas, as well as the stabilizing particles, are dispersed throughout the matrix metal.  The composite can then be formed by the introduction of a gas by a known technique to form a particle-stabilized metal foam.  The use of stabilizing particles that are not fully wetted by the matrix metal means that lower cost materials and mixing methods can be employed.  The entrainment of gas bubbles means that a microporosity is introduced into the composite, which is retained when the composite is transformed into a metal foam.

IPC: B60B9/00

Abstract: The relatively harsh "ride" of a non-pneumatic tire ("NPT") is greatly improved by a ring of elastomeric material referred to as a "ride-enhancing insert" ("RI"). The RI is pre-positioned on the outer surface of a wheel rim on which the NPT is to be molded of elastomeric material, most preferably a polyurethane, which is peculiarly well-suited to survive normal use on various vehicles, particularly as a replacement for a conventional spare tire, or "minispare" in an automobile. The RI is surprisingly tolerant of stress and heat loads generated by operation of the NPT/RI. The RI has a large effect on the spring rate of the NPT when deflected over a cleat, and a reduction in spring rate when deflected over a smooth laminar surface. This is of particular importance since the deflection over a cleat is where the improvement in ride is most noticeable. The degree of ride-enhancement can be tailored by choosing the size and shape of the RI, along with the physical properties of the elastomer from which it is formed. <IMAGE>

Title: Rock crushing machine
Inventor: FASOLI RALPH
IPC: B02C2/04
Filed: 1993-03-26
Abstract: A machine for crushing rocks is comprised of a main body, a bonnet which rests on the upper frame of the main body and a concave holder threadably inserted into the bonnet. The bonnet is maintained in intimate contact with the main body by means of a plurality of tramp iron cylinders while the concave holder is screwed into the bonnet by means of a adjusting gear and matching pinion. The concave holder is locked in position within the bonnet by means of a plurality of locking cylinders positively engaging a locking slide ring. A  mantle covered male conical member is driven by a crown gear and pinion in an elliptical rotation within the confines of a concave thus crushing the raw rock on each near pass. The concave holder will automatically lift and/or tilt off of the bonnet in response to the individual or collective actions of a plurality of tramp iron cylinders and matching accumulators which are reactive to an excess loading between the male conical member and its mantle and the concave. A two part stepped slip seal provides containment of excess lubricant which excluding abrasive particles from contact with critical components. The seal is incorporated as part of a thrust bowl which rides against the underside of the male conical member and absorbs crushing loads transmitted via the male conical member and the concave.

Abstract: FOAM GENERATING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE           A foam generating apparatus can be attached to a water  bearing  hose  and  comprises  an  eductor  nozzle  to receive water and foam concentrate, and a foam generating nozzle to discharge a foam/water mixture therethrough.   A foam  concentrate  conduit  delivers  concentrate  to  the eductor nozzle and has a concentrate valve to control flow therethrough, e.g. a one-way check valve to prevent water from passing outwardly through the foam concentrate conduit to   dilute   the   concentrate.      A   delivery   manifold communicates the foam concentrate conduit with a suction port of the eductor nozzle and extends peripherally around the suction port to permit foam concentrate to be drawn into the eductor nozzle for discharge therethrough.   The foam generating nozzle receives the foam/water mixture and has air entrainment openings to admit air into the mixture and  an  agitator  jet  orifice  for  agitating  the  mixture located generally adjacent the air entrainment openings. The  agitator  jet  orifice has  interconnected  inlet  and outlet jet openings in series, the outlet jet opening being larger than the inlet jet opening to provide a diverging passage with at least one step between the openings to agitate the flow.

Title: Protection and Recovery of Telephone Line Interface Circuits
Inventor: HUNG PAUL F
IPC: H04M3/00
Filed: 1993-11-10
Abstract: An automatic protection and recovery method for a telephone line interface circuit is described. The interface circuit monitors current on the line, and in the event of a fault producing an excessive current a protection relay interrupts a connection of the interface circuit to the line, and the interface circuit monitors common mode voltage on the line. The interface circuit is reconnected in response to the monitored voltage being below a relatively high threshold. If a second interruption results, the interface circuit is then reconnected in response to the monitored voltage being below a lower threshold. If a further interruption results, the interface circuit enters a ground fault recovery process. The method facilitates protection and rapid recovery from arbitrary fault conditions on the telephone line.

Abstract: An object code expansion program (5) inserts new instructions and data between preexisting instructions end data of en object code file (I); offsets are modified to reflex new positions of the preexisting instructions and data. For each item of preexisting object code (instruct-tion or data), the following steps are performed: making a new code block comprising any desired new instructions and the item, and storing it as new object code; tracking the location of the item and the new code block within the new object code; and tracking items that contain inter-item offset. Then, each inter-item offset is updated using the new location of the item or new code block, as re-quired. Finally, offsets in symbol tables and relocation structures are updated with the new location of the item.  This extension program is used to add instructions to ob-ject code files to monitor memory accesses of another pro-gram.
