Abstract: The present application relates to microfabricated columns having a sealed flow channel. In particular, the channel is sealed during dicing, thereby preventing debris from accumulating within channels. In use, the seal is ruptured mechanically to connect one or more fluidic connections, which deliver analytes to the flow channel. Additional details are provided for making and using sealed columns.

Abstract: The invention is a statistics based fantasy style interactive sports game of a predetermined duration that may be played in a bar or restaurant or over the internet. Each game takes place during a fixed time period (such as one hour), before which players choose a number of athletes from one or more sports that will be playing during that time period. During the course of the hour a player is awarded points for plays completed by selected athletes. At the end of the hour, the game player with the most points wins.

Abstract: A microwave intensification system includes a base frame having a plurality of support members, a microwave transparent, central vessel, and at least one dielectric unit positioned within the central vessel. A cooking surface is formed by covering the dielectric unit with a protective covering. In operation, a food item is placed within a processing container and positioned on the cooking surface over the dielectric unit. The processing container is sized such that an overlap exists between the container and the dielectric unit in order to balance the exposure of the food item to a microwave energy field. With this arrangement, the food item can rapidly undergo a cooking process in a manner wherein central and edge portions of the food item are exposed to a uniform cooking process thereby increasing the quality of the final product.

Abstract: The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO2), with reactants of nitrous oxide (N2O) or oxygen (O2).

Abstract: A machine such as an articulated loading shovel, has a working arm, the machine including a body part to which a first end of the arm is attached for relative pivotal movement about a first generally horizontal axis and the arm having a second end adapted to mount a working implement for movement relative to the arm about a second generally horizontal axis characterized in that the arm is substantially straight between the first and second ends, and is of substantially inverted channel configuration having a top part and a pair of side walls integrally formed, and the arm over at least a major portion of its length between the first and second ends including a strengthening member which extends between and is connected to the side walls.

Abstract: A universally stable oil-well-ship turret (1) has a circumturret cylinder (2) with an inside periphery sufficiently greater than an outside periphery of a turret cylinder (7) to allow vertical positioning of the turret cylinder within the circumturret cylinder in opposition to variations from verticality of the circumturret cylinder in response to effects of wave and weather conditions on a marine vessel in which the circumturret cylinder is positioned rigidly. A plurality of horizontal and vertical bearings (10, 11) are pressure-cylinder actuated to maintain horizontal attitude of a turret flange (8) from which the turret cylinder is extended downward vertically into the circumturret cylinder. Sensor-responsive automation that is self-checking for reliability, selective manual operation and computer controls (52, 54) are provided. Appropriate redundancy and backup are provided for all systems, components and features. A use method is described.

Abstract: A material-handling vehicle comprising a structure having a ground engageable propulsion device, a loader arm, having a longitudinal axis, mounted at the rear of the structure for up and down swinging movement, an operator's cab disposed on the structure on one side of the loader arm longitudinal axis and an engine mounted on the structure to provide power for the swinging movement of the arm and propulsion of the vehicle, wherein the engine is located on one side of the loader arm longitudinal axis and the engine has an output shaft and the engine is transversely disposed with its output shaft transverse to the vehicle.

Abstract: A transducer assembly (12) is applied to the surface of the body beneath an inflatable cuff (10). Transducers (12c) are disposed upon a substrate (12a) and may include from one to some large number of transducers suitable for detecting an oscillation resulting from arterial blood flow within a partially occluded artery. Each transducer (12c) can be of large size, relative to an artery (16), to eliminate a requirement that the transducer be accurately placed over and maintained upon the artery. The substrate can be provided to have a surface with a radius of curvature selected to approximate a curvature of the extremity to which the transducer array is applied. The cuff pressure is increased to a level above the systolic pressure of the individual and then gradually reduced. Oscillations are sensed by one or more of the transducers as the cuff pressure is decreased. When the systolic pressure is reached, the sensed oscillations begin to increase in amplitude until they reach a maximum amplitude.

Abstract: A vascular graft which incorporates a flexible shunt to significantly reduce the time that blood flow to vital organs and extremities is interrupted during removal of diseased sections of a blood vessel.

Abstract: A heat sink assembly for protecting at least one electronic device is provided which comprises a heat sink and a clip. The clip includes first and second opposed end portions and an interconnecting intermediate portion. The first end portion is pivotally anchored. In order to bias at least one device against the heat sink, the intermediate portion includes at least one spring member resiliently engageable with at least one electronic device. The second end portion removably fastens the clip to the heat sink.

Abstract: A laryngoscope blade comprising an essentially straight blade portion have the inner end portion which is curved out of the plane of the straight blade portion, and which curved portion is adapted to be received in the groove defined between the base of the tongue and the epiglottis of a patient whereby the tip end causes the tongue to be moved anteriorly to expose the inlet of the larynx and the straight portion of the blade defines a line of sight directly into the larynx.

Abstract: This disclosure is directed to an improved laryngoscope blade of the straight blade type, which includes an essentially straight blade portion having a arcuate cross-section and which has connected to a longitudinal edge of the arcuate blade portion an outwardly flared flange so as to reduce the overall height of the blade while maximizing the exposure or vision through the blade to the larynx.
