Abstract: A wellsite pumping system, comprising a gas processing system including a source of compressed gas, the source of compressed gas having a low pressure inlet and a high pressure outlet, coil tubing connected to the high pressure outlet of the gas processing system, the coil tubing including a first tubing string connected to the high pressure outlet and a second tubing string running parallel to the first tubing string and having an opening for entry of fluid at a remote end from the high pressure outlet; and a venturi connecting the second tubing string to the first tubing string such that, in operation, passage of gas through the venturi from the first tubing string draws production fluid into the second tubing string. Preferably, the second tubing string is suspended within the first tubing string. The venturi may be formed by a horizontal passageway communicating with a vertical passageway with a restriction.

Abstract: A drill resistant plate, which presents a rough surface of hardened particles to drilling attack, and which tends to snap or destroy drill bits before they can began drilling. The plate is made by brazing hard particles into a matrix of brazing material attached to a steel plate. Nickel-Silver brazing material is used to form the matrix on the steel plate, and tungsten carbide particles of 8-10 mesh are secured within the matrix, with the hard particles of tungsten carbide partially exposed, presenting a roughened surface with angular pieces of tungsten carbide to the drilling attack.

Abstract: A motorized dump-type vehicle is provided having a chassis frame, an engine mounted on said frame, a dump container pivotally mounted on the front of said frame and a hydraulic system enabling said container to be raised and lowered by a hydraulic cylinder and said vehicle to be driven in either forward or reverse directions using its front wheels. Additionally, as needed, the vehicle can be switched into all-wheel-drive by hydraulically driving the vehicle's rear wheel(s) which are by default undriven.

Abstract: A sterilization cassette and a sterilization method for sterilizing, storing, and dispensing dental instruments. The sterilization cassette includes a mounting bar and a locking bar for dental pliers of various types, a removable instrument tray, and a case with a front side which opens and hinges in two places, allowing the cassette to be arranged in horizontal and vertical configurations.

Abstract: A grid interposer for testing electrical circuits and a method of making a grid interposer. The grid interposer includes upper and lower conductive surfaces sandwiched on either side of an insulating later, connected to each other by a plurality of vias filled with conductive material. The conductive surfaces are flat topped, and incised with a grid of flat topped peaks which are small enough to cut through oxidation of electrical contacts, and ensure good electrical contact with a variety of electrode shapes.

Abstract: A device for smoking food items using charcoal briquettes as fuel. The device has a channel into which the charcoal briquettes are placed so that ignition of one of the charcoal briquettes will result in eventual ignition of the adjacent charcoal briquette. The device is preferably placed in a standard barbecue grill, thereby allowing a user to smoke meat or fish using charcoal briquettes and the charcoal barbecue grill they already own.

Abstract: A description is given here of a novel process for the production of monocarboxylic and polycarboxylic aromatic acids by the catalytic oxidation in homogeneous phase of aromatic compounds carrying at least one oxidizable substituent group attached directly to the carbon atom of the corresponding aromatic nucleus. The novel process according to the present invention comprises the steps of: a) catalytically oxidizing the corresponding aromatic precursors in liquid phase in the presence of gaseous oxygen; b) filtering the end product; c) recycling into the oxidation reactor at least part of the mother liquors resulting from the filtration stage, and is characterized by the fact that said steps from (a) to (c) are carried out in a closed and continuous cycle operating substantially under the same pressure and temperature conditions, preferably at 2-10 barg and 100-140° C.

Abstract: An automatic depth of cut control for use with concrete saws. The control allows an operator to set a maximum depth of cut for which the concrete saw can be used at. Further, the control allows the user to move the concrete saw from one location to another without needing to reset the depth of cut.

Abstract: The invention is a particle separator which separates entrained particulates from a fluid. The particle separator utilizes an auger enclosed within a cylinder to form a cyclonic chamber, through which air is propelled. The centrifugal motion of particles within the air causes the particles to exit the cyclonic chamber through ducts, and the particles are separated in collection chambers.

Abstract: A three-tank carpet spot cleaning device having a cleaning fluid tank, a rinse water tank, and a recovery tank. In use, a user uses cleaning fluid to spot treat the spot, and then is able to rinse all residue of the cleaning fluid from the carpet using the rinse water.

Abstract: A trailer alignment device for simplifying the backing of a tow-vehicle to a trailer. The device utilizes a number of ultrasonic transducers to gauge the location of the tow-vehicle to the trailer. This information is transmitted to a control unit that analyzes such data and creates a visual display for the operator to use in backing the tow-vehicle to the trailer.

Abstract: A method and system for communication and trade on a network, in which information is directed at the computer screen of a consumer by merchants of goods, services, or information. A lending partner would provide the initial capital to offer the consumer an incentive for signing up for the system, and for supplying pertinent information about herself. A management system would integrate the merchant information with consumer information, to send a targeted stream of information to the user. Purchases could be made from the system, whether connected to the network or not. Background data transfer or auto-refreshing of data would be options for the system. The lending partner would be repaid for the consumer's incentive from revenues paid into the management system related to each individual consumer transaction.

Abstract: Disclosed is a tool for marking a pair of points on a horizontal line. The tool has a standard ruler onto which is slidably attached a first member, a leveling member, and a second member. The first member is used to mark the first point and the device pivots at the first member. The user then determines when the first member is level with second member through using the leveling member. When level status is obtained, the user is able to mark the wall or other surface at the second member, thereby resulting in marking pair of points on a horizontal line.

Abstract: A front receiver assembly for use with vehicles having front tow hooks. This front receiver assembly attaches to a vehicle's front tow hooks and can be mounted or dismounted quickly. This front hitch assembly is adaptable for use with nearly any hitch connector product.

Abstract: A front spotting trailer hitch assembly for use with vehicles having front tow hooks. This front hitch assembly works well for easily back trailers into positions, such as for storage. This front spotting trailer hitch assembly attaches to the front tow hooks and allows a user to attach a hitch ball to the hitch assembly for towing. This front spotting trailer hitch assembly is able to be quickly attached and detached from the vehicle having front tow hooks.

Abstract: An apparatus and method of testing an individual to identify whether the individual is experiencing: (a) solely an attention disorder (ADD) based upon a low sensory arousal system; (b) another disorder (attentive-type); or (c) a combination of low sensory system attention disorder (ADD) and other attentive disorders.

Abstract: A shuttle valve for use in a pumping apparatus for pumping concrete or the like. The valve uses belleville springs to hold a wear ring against the concrete hopper, thereby creating a seal.
