Abstract: A landing gear door assembly for an aircraft, having a closed position to cover the door opening through which the landing gear moves between its stowed and operating position. The door assembly comprises two panel sections, each of which is rotated by a related positioning section so as to rotate about a center of rotation from the closed positions upwardly and outwardly into the aircraft structure to the open position. In one arrangement, each panel section is made up of an inside and outside panel which are hinge mounted with respect to one another. These move in a manner that the outer panel moves in a path deviating from a straight rotational path to provide better clearance with the aircraft structure. In another arrangement, each panel section is rigid and is rotated about a fixed axis of rotation.

Abstract: An egg concentrate having a higher percentage of solids relative to whole eggs. A liquid yolk component is mixed with a dried albumen component to form the egg concentrate. This can be reconstituted by mixing it with water, and this reconstituted egg product can be used itself as a food product, or mixed with other ingredients to make such things as bakery products, mayonnaise, etc. In one preferred embodiment, the concentrate is combined with an ingredient or ingredients (e.g. sugar and/or salt) to lower its water activity and make the concentrate shelf stable for relatively long periods (e.g. 2 months or much longer). In an alternative embodiment, another procedure is employed where a similar result of the dispersion of the powder in the yolk component is accomplished.

Abstract: A door assembly for a landing gear of an aircraft. The door assembly comprises a door section that in turn has two panels, moveable between closed and open positions by a positioning section. In one embodiment, the positioning section comprises mounting arms fixed to the panels which are connected by parallel linkages and which move the panels in a rotational path from a closed position aligned with the door opening through a path of rotation to a location spaced laterally of the door opening, with the panels being in proximity with another and these partially overlapping. In another arrangement, the inside surfaces of the panels face one another in the open position, and the panels are hinge mounted to one another.

Abstract: This patent application is to use dynamic electromagnetic wave reflection and refraction methods for prospecting for oil directly. The available geophysical methods including the most used seismic reflection method are all prospecting for oil indirectly, viz., aiming at finding the geological structures and stratigraphic traps, etc. The high contrasts of electric permittivity between oil cord the surrounding geological formations of rocks including gas, water (fresh and salt), on the other hand, make it possible to use the dynamic electromagnetic wave reflection and refraction methods for prospecting for deep seated oil directly.

Abstract: A method of processing a ceramic body, such as a saw tip so that the ceramic body can be bonded to a substrate, such as a saw blade. The ceramic body is desirably a cermet, and it is first cleaned, preferably using sodium hydroxide. After this, the ceramic body is etched by an acid, after which a metallic coating is applied to the bonding surface either by electrolysis by an electroless process. Then the ceramic body is either brazed or welded to the substrate.

Abstract: A portable parts washing machine using a washing solvent to wash motor parts or the like. The apparatus has a stowed configuration and an operating configuration. In the operating configuration, a solvent container/wash basin is positioned on a base section which also functions as a solvent reservoir. Solvent is recirculated by a pup and recirculating line fro the reservoir to the wash basin, with the solvent washing the parts and then flowing through a drain in the wash basin into a centrifugal filter. The centrifugal filter removes the contaminates, with the solvent returning to the reservoir. In the stowed configuration, the base section, centrifugal filter and solvent recirculating assembly are stowed in the container.

Abstract: A method of detecting corrosion on an elongate member, such as a pipe. Far side and near side electric pulses (waves) are transmitted into a magnetically permeable pipe at spaced locations to travel toward one another. These are synchronized to intersect at various locations on the pipe. The resulting wave forms are analyzed by combining adjacent wave forms resulting from pulses intersection at spaced locations. Two combined wave forms are analyzed by subtracting one from the other to produce a difference wave form and the difference wave forms are compared to detect corrosion.

Abstract: A structurally reinforced snowboard comprising upper and lower reinforcing components positioned at upper and lower surface regions of the snowboard. The upper and lower reinforcing components have reinforcing strip portions which are vertically aligned with one another. In one preferred configuration, these extend along end side portions of the board and converge toward an intermediate location. In other configurations, these cross with one another. The arrangement improves torsional stiffness of the board, while permitting the desired flexural stiffness profile to be obtained.

Abstract: A matrix display sign and system where the displayed image or message can readily be changed. There is an array of pixel units arranged in rows and columns, and each of these pixel units can be selectively activated to display various selected colors. In a preferred embodiment, each pixel unit is capable of displaying any of a blue, green, red, white or black color. Each pixel unit has an elongate strip member having pixel sections, each having a different color characteristic. The pixel strip is moved in increments so that various pixel sections can be moved into a display region where either reflective light or transflective light illuminates the pixel section. A solenoid driver is activated to move in stepped increments to move the pixel strip to selected positions at the display region.

Abstract: A system for shipping perishable product in a controlled atmosphere environment, by means of various transport containers and/or vehicles. Quantifies of the product are placed in flexible containers or bags having a controlled atmosphere inlet and a gas outlet, to form shipping units. The shipping units are placed in a containing section of the transport vehicle or structure, and the individual shipping units are supplied with the controlled atmosphere gas from a suitable gas source or sources having a gas regulator or regulators. During shipment and storage, controlled atmosphere gas is directed into the shipping units as needed to maintain the proper atmosphere within the shipping units. When arriving at a destination, the quantities of perishable product are either removed from the shipping units, or kept in the shipping units for further storage and/or shipment.

The laser mounting device can be swung to upper and lower positions.

Abstract: An absorbable prophylactic composition for protecting against ionizing or nonionizing electromagnetic waves. The composition is derived from a crude extract of residual fractions of crushed grapes, and primarily from solid material comprising pips, stalks and skins of grapes and/or combinations thereof. The crude extract is obtained by first pulverizing the fraction or fractions from the grapes to form a powder, and then subjecting the powder to at least two extraction processes, one with acetone and the other with ethyl acetate. The extract is then ingested in doses between about 20 mg to 3 g for an adult male. Tests have demonstrated the efficacy of this composition against changes induced by ionizing radiation (x-rays) and nonionizing radiation (UV-C).

Abstract: A mounting apparatus for a radar unit by which the unit is mounted to the three ropes of a backstay of a yacht. There is a mounting plate having three connecting openings which connect to the free ends of a main line from the mast and two bow lines. The lines are tensioned to hold the mounting plate in a position above the deck. A mounting platform is connected by a rotary connection to the back plate, and the radar unit (by the force of gravity) remains level.

Abstract: A method and apparatus to repair dents formed by a golf ball impacting the surface of a golf green. A restoring tool is mounted to the top of the handle of a putter, and this tool comprises a base member and a ground penetrating portion which is formed as a pair of tines and which is rotatably mounted to move from a stowed position flush against the base, to an operating position where it extends at right angles to the base. The putter is inverted so that the end of the handle can be positioned against the raised edge of the dent. The tines (outwardly extending) are moved to penetrate into the soil at a location outwardly of the raised edge of the dent, and the compression surface of the base member presses the sod layer downwardly and displaces the underlying ground layer laterally to fill into the recess portion of the dent. This also causes the displaced portion of the sod laterally over the dent.

Abstract: A detection system for small water craft, such as a kayak. Radar reflective material is incorporated in the surface of the kayak or other water craft, and also is incorporated in surface areas of water craft accessories, such as cushion, life vest or paddle. When the smaller water craft is in the vicinity of a larger aircraft which may be radar equipped so that there is danger of a collision or where the water craft is in a position where it would want detection as part of a rescue effort or the like, the water craft is oriented so that the radar reflective surface would reflect radar back to the sending source, thus better enabling detection. Also, the paddle or other water craft accessory could be positioned so as to reflect the radar waves. Further, the paddle or other accessory could be oriented to reflect the radar waves back to the source, or do so intermittently, in the event that the radar system is programmed to ignore a constant reflective signal.

Abstract: A flotation assembly made up of a load bearing structure which can be an off-shore platform, and also a flotation section comprising a plurality of flotation tubes. Each of the flotation tubes comprises a surrounding side wall defining a vertically aligned elongate pressure chamber and having an upper end closure portion that has a downwardly facing surface exposed to pressure in the chamber. The tubes are positioned at laterally spaced locations and arranged relative to the load bearing structure so as to create upwardly directed flotation forces that bear against the load bearing structure. A source of pressurized gas is transmitted to the flotation tubes to a level where the gas pressure within each tube creates a force against the side walls to alleviate compressive force of the surrounding water pressing inwardly against the side walls of the flotation tubes.

Abstract: A rear suspension system for a bicycle. The system directs the rear wheel along a predetermined, S-shaped path as the suspension is compressed. The path is configured to provide a chainstay lengthening effect only at those points where this is needed to counterbalance the pedal inputs of the rider; at those points in the wheel travel path where there is a chainstay lengthening effect, the chain tension which results from the pedal inputs exerts a downward force on the rear wheel, preventing unwanted compression of the suspension. The system employs a dual eccentric crank mechanism mounted adjacent the bottom bracket shell to provide the desired control characteristics.

Abstract: An automated low clearance skirt assembly lifting device adapted for raising and lowering a circular or multifaceted skirt to match the opening of pressure vessels such as coking drums and a method for uniform remote operation of the assembly. The low clearance skirt lifting assembly includes a reinforcement of the upper skirt attached to one or more lifting cylinders mounted within a telescoping enclosure, so that the skirt assembly may be uniformly extended and retraced without binding or side load transfer to the hydraulically or pneumatically actuated device. Following the unheading of the flange on the coke drum, the skirt is remotely extended to align with the flange hereby bridging the gap between the chute and the drum prior to commencement of the drilling cycle and lowered once all the coke has been extracted from the drum.

Abstract: A method and system for detecting corrosion on a pipe or a pipeline. An electrical or electromagnetic pulse is transmitted into a pipe or pipeline to travel as a propagating electromagnetic wave along the pipeline to a receiving location. Both the distance traveled from the transmitting and receiving location, and also the time interval for such travel are measured. Velocity of the wave is detected as a means of ascertaining whether corrosion is present. Various embodiments, using both multi-channel and single cables, are used to transmit the detected waves, and the waves are received at a plurality of spaced locations along the length of the pipe or pipeline. For an insulated pipeline, the signals can be received by a directional antenna, and the pulses can be transmitted into the pipeline by means of either an antenna placed directly adjacent to the pipeline or a magnet electrical contact member in direct contact with the pipeline.
