Abstract: The methods described herein generally relate to preparing and delivering a fluid mixture to a confined volume, specifically an annular volume located between two concentrically oriented casing strings within a hydrocarbon fluid producing well. The fluid mixtures disclosed herein are useful in controlling pressure in localized volumes. The fluid mixtures comprise at least one polymerizable monomer and at least one inhibitor. The processes and methods disclosed herein allow the fluid mixture to be stored, shipped and/or injected into localized volumes, for example, an annular volume defined by concentric well casing strings.

Abstract: A process is described for replacing at least a portion of the liquid within the annular volume of a casing system within a wellbore with a second liquid. The second liquid comprising at least one polymerizable monomer and at least one antistatic agent to control build up of static charge. The second fluid is preselected to provide a measure of control of the pressure within the annular volume as the fluid within the volume is being heated.

Abstract: An automatic and initial adjustment of pertinent engine parameters to provide an engine with a gentle break-in period. The engine's electronic control unit adjusts the engine parameters most conducive to proper break-in during operating speeds greater than a predetermined speed and for a predetermined period of break-in time.

Abstract: An improved bracket and idler assembly for an internal combustion engine in which the bracket forms a portion of an air compressor for use with the engine.

Abstract: A marine propulsion device comprising a transom bracket adapted to be mounted on a boat transom and including laterally spaced rearwardly extending port and starboard portions, and a swivel bracket including a first leg connected to the transom bracket for pivotal movement about a horizontal axis and a second leg extending generally perpendicularly to the first leg and including a transversely extending portion extending in closely adjacent relation to both of the rearwardly extending laterally spaced transom bracket portions and substantially bridging the space between the rearwardly projecting laterally spaced transom bracket portions.

Abstract: A marine propulsion device includes a support adapted to be attached to a boat hull and a propulsion assembly including a propeller adapted to be driven by an engine. The propulsion assembly is connected to the support for vertical pivotal movement relative thereto and a hydraulic tilt cylinder and piston assembly is connected at one end to the support and has a second end connected to the propulsion assembly. The piston is movable toward the other end of the cylinder when the one end is pressurized to tilt the propulsion assembly upwardly. At least one trim cylinder is fixed relative to the support and includes a trim piston reciprocally mounted on the cylinder and releasably engageable with the propulsion assembly. Actuation of the propeller while the propulsion assembly is tilted upwardly is operative to force the propulsion assembly downwardly against the piston.

Abstract: Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be mounted on a boat transom and including a rearwardly and laterally open socket, a swivel bracket connected to the transom bracket for pivotal movement about a horizontal tilt axis, a trail arm pivotally mounted on the swivel bracket for movement between a retracted position adjacent the swivel bracket and an extended position projecting from the swivel bracket and including an outer end receivable in the socket in the transom bracket and having a laterally extending projection, a latch member pivotally mounted on the transom bracket for movement between a retracted position and a latching position, which latch member includes a hook located, when the latch member is in the latching position, for engagement with the projection to prevent withdrawal of the outer end of the trail arm from the socket, and which hook is located, when the latch member is in the retracted position, clear of interferring engagement with travel o

Abstract: Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be mounted on a boat transom and including an upper surface, a swivel bracket connected to the transom bracket for pivotal movement about a horizontal tilt axis, a holding member pivotally mounted on the swivel bracket for movement about a horizontal second axis between a park position, a low-tilt position, and a high-tilt position, which holding member includes a low-tilt abutment surface engageable with the upper surface of the transom bracket when the holding member is in the low-tilt position and extending perpendicularly to a radial plane extending through the second axis and at a first radial distance from the second axis, a high-tilt abutment surface engageable with the upper surface of the transom bracket when the holding member is in the high-tilt position, which high-tilt abutment surface extends perpendicularly to a radial plane through the second axis and at a second radial distance from the second axis greater

Abstract: A marine propulsion device comprising a transom bracket adapted to be affixedly mounted on the transom of a boat, a propulsion unit mounted on the transom bracket for pivotal movement relative thereto about a generally horizontal tilt axis, an extendable and contractable link connected between the transom bracket and the propulsion unit for pivoting the propulsion unit about the tilt axis, and a mechanism for stopping pivotal movement of the propulsion unit in response to the position of the link relative to the propulsion unit.

Abstract: Disclosed herein is an internal combustion engine comprising first and second cylinders and first and second cylinder head cavities respectively aligned and communicating with said first and second cylinders to respectively define compression ratios respectively associated with each of said first and second cylinders, and means for providing each of said first and second cylinders with respectively different compression ratios selected to maximized the power produced in each cylinder without knocking.

Abstract: A novel hyperbaric oxygenation apparatus, and related methods, the apparatus comprising a chamber in the form of a disposable inflatable bag of impervious inexpensive synthetic resinous material which can be used at any desired location, such as a hospital, a home or other site where oxygen can be appropriately made available. The pressure of the oxygen in the collapsible bag is pulsated between maximum and minimum positive values. The patient cyclically experiences first a medicinal increase in the blood gas levels in the limb under treatment with a corresponding restricted blood flow and, thereafter, a progressive return to normal blood flow rates in the limb of the patient as the pressure in the chamber changes from maximum to minimum positive pressure. A respirator, normally used for intubated respiratory patients, in conjunction with a single oxygen influent/effluent port in hyperbaric oxygenation apparatus is efficacious to provide the oxygen and generate the desired pressure variations.
