Abstract: Systems and methods to efficiently get precision geometry for a graphic object on a thin client application such as running on a browser or hand-held device. Specifically, a Precision Geometry Client running on a client device sends requests to a corresponding Precision Geometry Service running on a server system to obtain precision geometry primitives that the client device, thereby offloading the processor-intensive precision geometry processing from the client to the server system.

Abstract: A high efficiency energy conversion system disclosed herein incorporates a piston assembly including a sealed cylinder for storing a working fluid and an energy conversion element attached to the piston assembly. A kinematic mechanism such as a cam lobe or a scotch yoke may be used as the energy conversion element. In one implementation, the kinematic mechanism may be configured to provide rapid piston expansion in a manner so as not to allow the expanding working fluid inside the piston to achieve thermodynamic equilibrium. In an alternate implementation, the kinematic mechanism is further adapted to generate a compression stroke in a manner to provide the working fluid inside the piston to achieve thermodynamic equilibrium conditions throughout the compression stroke.

Abstract: The invention is a Perforated One Piece Outer Case Packaging Wallet that includes a perforated design pattern on the front side of the package; and this allows it to function as a wallet. This invention will commonly store an independent inner package. The Perforated One Piece Outer Case Packaging Wallet can store additional items such as credit cards, IDs, money, and other small items for products like gum, cough drops, candy, and various other small items.

Abstract: An apparatus and a method to control rotational positioning of continuous concentric tubing that extends from a surface downhole in a subterranean well or bore. In one version, a continuous cylindrical inner tube resides within and is concentric with a cylindrical outer tube. At least one elliptical lobe extends from the continuous inner tube. The invention utilizes diameter restrictions within and attached to the outer concentric tubing so that the elliptical lobe or lobes engage the diameter restrictions. Accordingly, rotation of one tube rotates or orients the other tube.

Abstract: An abrasive cutting or drilling system, apparatus and method, which includes an upstream supercritical fluid and/or liquid carrier fluid, abrasive particles, a nozzle and a gaseous or low-density supercritical fluid exhaust abrasive stream. The nozzle includes a throat section and, optionally, a converging inlet section, a divergent discharge section, and a feed section.

Abstract: A top plate alignment template device for subterranean drilling or boring. The template device includes a frame receivable on a ground site. A plurality of tubular guide bores are provided on the frame, with each of the guide bores arranged at an angle extending downwardly and outwardly from the frame. In one embodiment, each of the guide bores has an axis so that the axes of the guide bores extend from a common center point above the frame.

Abstract: An insulative piston or piston cap creates a highly thermally resistive path in the axial direction of the piston or piston cap toward a crank case of an engine. An insulative cylinder is configured to be positioned around the insulative piston and adjacent an insulative cylinder head, and to provide thermal resistance in the cylinder's axial direction. The insulated cylinder head is configured to resist heat flow in the axial direction away from the crank case. High temperature insulation surrounding these structures is configured to resist heat flow out of a combustion chamber of the engine. These insulative components, together, form the fully insulated combustion chamber.

Abstract: A method and apparatus for creating inverted laterals or drainholes for producing from a subterranean reservoir including the steps of lowering, positioning and securing a reverse whipstock in a wellbore. A tube is secured from the surface to a pull tube which extends through and below the reverse whipstock. Fluid is pumped from the surface and through a U-tube device below the pull tube. At least one inverted drainhole is drilled using force from the pumping fluid. The pull tube is pulled upward vertically toward the surface while pumping the fluid.

Abstract: A training aid is described for facilitating a user swinging a golf club having a golf club head over a ground surface. The training aid includes a resilient spacer having an upper side, a lower side, and at least one peripheral edge connecting the upper side to the lower side, and an attachment means fixed to the spacer and adapted to selectively hold the spacer to the golf club head. With the training aid mounted to a lower side of the golf club head with the attachment means, the user may swing the golf club over the ground surface, the spacer preventing the golf club head from contacting the surface. In some embodiments, a cushioning means may be fixed to the lower side of the spacer.

Abstract: A flashback-arresting shut-off valve is disclosed herein. Propellant is moved from a propellant reservoir, through the shut-off valve in an open configuration to a point of combustion in a normal propellant flow direction. During a flashback, the propellant is ignited within the propellant line and substantial physical/thermal energy caused by the flashback travels in the direction opposite to the normal propellant flow direction back to the shut-off valve. A burst member within the shut-off valve fails because of the flashback. Failure of the burst member causes compression on a spring-loaded portion of the shut-off valve to be released, thereby closing the shut-off valve and sealing the propellant reservoir from the flashback. Failure of the burst member also causes one or more pressure relief outlets to open that direct the physical/thermal energy and/or un-combusted/combusted propellant out and away from the shut-off valve.
