Abstract: A hydrocarbon thermophotovoltaic (TPV)electric generator insert has applications as a replacement burner to retrofit existing appliances. The retrofitted appliance is thus upgraded to either a cogeneration or self-powered unit. The design of the TPV burner insert is independent of the appliance to be retrofitted except for external adapters and can be easily retrofitted to any appliance design requiring a hydrocarbon burner. The burner uses fully premixed air and fuel near stoichiometry to attain a short duration, high intensity burn through optically dense porous ceramic emitters. The emitters attain temperatures between 1300° and 1500° C. The infrared radiation is collected by low bandgap photovoltaic cells with optical response at least out to a wavelength of 1.7 micrometers such as GaSb cells to produce DC power. The circuit cooling system uses fans or circulating water for cooling.

Abstract: A moisture control device and method has a heat generating source in electrical devices that is powered to operate independent of the electrical device for reducing, minimizing or preventing condensation, nucleation and degradations on electronic parts and circuit boards of the electrical device. A power supply is connected to the heat generating source and a switch connected to the power supply. The switch may be manually operable or automatic and is used for controlling operation of the heat generating source. A sensor senses on/off status of the electrical device and automatically operates the switch in response to the sensing. Power is supplied to the heat generating source when the electrical device powers down and disconnected when the electrical device powers on.

The invention provides that the mutual compression between rolls (1, 2) is exerted (4, 5, 106, 21, 22, 25, 26) over the whole axial length of the rolls (1, 2). This may be obtained through mechanical (6) or magnetic (21, 22, 23, 25, 26) means.

Abstract: A pulley-less shed-forming device for a weaving machine, such as a jacquard machine, has a number of shed-forming elements (1), such as hooks, to determine the positions of one or more warp yarns on a weaving machine. A lifting device (50), (51) moves the shed-forming elements (1) up and down. At least one actuator (40)-(44), (80), (83) is provided for selectively influencing the shed-forming element (1), so that it is either kept at a fixed height, or is moved by means of the lifting device (50), (51). The element (1) has at least one selection body (7), (8), (9) which, for said selective influencing, may be moved into first or second stable positions, as desired, by an actuator (40)-(44), (80), (83) forming a shed-forming element (1) in itself. It may also be formed as a device without a pulley. Because the positions of the selection body are stable, their position may be changed by a single temporal influence by the actuator making the device energy efficient.

An adjusting bubble element is fixed at the basic body element so that the middle part thereof is aligned parallel to the axis. The basic body element has an essentially L-formed profile whereby the adjusting bubble element is on one side which is angled at 90° in respect of the angle side, and the pivotable bubble element is on the other side of the angle of the basic body element.

Abstract: The Noise Suppressor II provides procedures and add-on units, which are attached to standard analog or digital ultrasonic flaw detector instruments for either suppressing noise spikes that clutter the flaw detector screens, or other undesired signals, or enhancing weak, barely detectable signals. The add-on units may do both simultaneously as well. Each unit includes an adjustable filter so that a user may tune the filter bandwidth to a specific range within the overall transducer band that coincides with the signal to be either suppressed or enhanced.

Abstract: A device for guiding the knife-supporting beams in a jacquard machine is provided. The device is for rectilinear guiding of a body (1) of a shed-forming device that can be driven in a back and forth movement. The device has a rod mechanism (2, 3, 4) of which a first (2) and a second rod (3) are rotatably connected to respectively the aforesaid body (1) and a fixed part (11). This rod mechanism is provided to exert a rectilinear movement on the joint (5) between the body (1) and the first rod (2) while driving the body (1). The joint (5) between the first rod (2) and the body (1) moves for that purpose preferably in a straight line through the joint (7) between the second rod (3) and the fixed part (11). This device is especially utilized as a shed-forming device of a machine of the Jacquard type for the rectilinear guiding of knife-supporting beams. Such a rectilinear guide has the advantage that it can be implemented with only hinge points that require no maintenance.

Abstract: A safety device provides quick and easy removal or separation of a part or assembly from a machine or installation base. The safety release fasteners that secure the part or assembly to the machine or installation base have interconnected sections that are releasable by simply tugging on the part or assembly to allow the sections to snap apart. The breaking of the fastener releases the part or assembly from the machine or installation base, thereby freeing from imminent danger the person, whose hair, clothing or limb may be caught. Axial separation of the fasteners prevent injury to a person or damage to a machine or installation base or to a part or assembly, such as when a large inanimate object is drawn into an intake of a machine or installation.

Abstract: In face-to-face weaving pile fabrics with high pile density, groups of three weft yarns (1-3), (4-6) are inwoven in respective openings between binding warp yarns (7), (8), (9) (10) crossing each other, and non-pile-forming pile warp yarns are inwoven, while pile warp yarns are alternately interlaced in the top and the bottom backing fabric over a weft yarn according to a two-shot weave. In series of four successive weft insertion cycles in each case three weft yarns (1), (2), (3) are inserted for the top backing fabric (30) and three weft yarns (4), (5), (6) for the bottom backing fabric (31). A weaving machine inserts two weft yarns one above the other per weft insertion cycle and by weft disengagement or weft cancellation in the course of two cycles per series inserts only one weft yarn. Two pile-forming pile warp yarns after a pile change are interlaced over a weft yarn.

Abstract: A method for manufacturing a loop pile fabric with a varied appearance includes a woven backing fabric. Loop weft yarns (12A), (12B) are provided outside the backing fabric, and loop warp yarns (1), (2), (3) are so provided that they are alternately inwoven in the backing fabric and form a pile loop (13), (14) over at least one loop weft yarn (12A), (12B), and the loop weft yarns (12A), (12B) are subsequently removed. By providing first (12A) and second loop weft yarns (12B) with a different thickness, pile loops (13), (14) of different height are formed. To obtain a fabric in which both pile loops (13) and cut pile (15) occur subsequently a top part can be removed from a number of pile loops (13). In areas (19) where no pile loops are formed effect backing weft yarns (11B) with laterally protruding filaments can be inwoven in the backing fabric. A loop pile fabric can be manufactured according to this method.

Abstract: A product building system uses a stage movable in X-Y-Z directions for holding and moving a product. A fixed laser is focused on a spot on the products. Strips of materials are fed tangent to a forming direction from two sources on a rotating platform. The laser continuously or periodically welds and fuses a strip on the product. Relative motion bends the strip to the desired product shape. The laser cuts a strip and welds a new strip to form alternating layers. Side by side strips are butt-welded. Cores are formed differently from outer surfaces,using the continuous feeding, welding, fusing, bending, welding and fusing process. A mill on the rotating platform brings a mill end tool into contact with the layers to smooth lateral and upper surfaces.

Abstract: The new buckle is made of two pieces which work with laminated strap webbing or open weave strap webbing. Web engagements within the buckle prevent the web from sliding through in any direction, or allow the belting to move in only one direction. Bases of side extensions of the inner plate have locking lugs. Moveable rounded side portions of the outer plate have locking tabs which engage the lugs to prevent movement out or into the locking position. Locking and unlocking the buckle requires squeezing rounded sides together while pushing or pulling on the outer plate. Teeth extend inward from the outer locking plate. Angled through-holes in the lower plate receive the teeth and hold the locking teeth in engaged position when the buckle is locked. Locking teeth angularly mounted in recesses in the upper plate are deflected when the webbing strap is pulled in a tightening direction.

The groups are housed in a box (1) which has substantially the dimensions and the shape of a sleeper and which is fitted in the track in place of and with the function of a sleeper. The switch box has movable device (23, 24, 124) to lock the blades (A1, A1′, A2, A2′) in their corresponding closed positions.

Abstract: A new DVD or CD package has thin disc-retaining straps which are vertically rigid and are bendable horizontally between bi-stable opposite curves. Opposite edges of discs are held by inward curved straps. A user flexes the straps outward into outer stable positions before removing the discs. Closing the cover of the box moves the straps to their inward curved stable positions. Ramps attached to the spine and to the outer edge of the cover push the straps inward. The ramps, or ribs, also prevent the straps from being pushed to an unlocked position when the case is closed. The straps are molded in inward, disc-holding positions through openings in the back of the tray. The straps are configured to hold one or more discs positioned in the cylindrical well of the tray, which is formed by four segmental curved walls. Finger wells extend between the segmental walls and through the base of the tray and are preferably located at 90° intervals to the straps to provide ease in removing the discs.

Abstract: The invention is gas-filled cavities that reduce drag on the underwater surfaces of marine vehicles. Hydrofoils, struts, boat and ship hulls, pontoons, underwater bodies, fins, rudders, fairings, protuberances, submarine sails and propulsors are underwater surfaces that may be covered by the gas-filled cavities to reduce drag on them. The gas-filled cavities are to be used on underwater surfaces of marine vehicles, such as hydrofoil craft, monohulls, catamarans, SWATH (small waterplane area twin hull) craft, SES (surface-effect ships) and WIG (wing-in-ground effect) vehicles. Each gas-filled cavity is formed by ejecting air near the end of each nosepiece. Air is ejected at a speed and direction which is close to that of the water at the local cavity wall. The cavity is formed behind the nosepiece. The nosepiece is adapted to control the shape of the cavity.

Abstract: A model building apparatus includes a beam delivery module and a stage movable in the X, Y and Z directions. A feedstock holding mechanism for the model building apparatus enables the model building apparatus to corrugate the feedstock into a latticed layer. The feedstock holding mechanism includes a feeder housing a spool of feedstock and jaws having push-down arms and side-holding arms. Engaging and disengaging of the feedstock by the jaws while moving the table allows for forming a latticed layer of feedstock that is several times thicker than the thickness of the feedstock. Reducing the total number of layers that comprise the model significantly increases the speed of constructing models that do not require solid walls. The latticed layers may be formed in a continuous process without cutting the feedstock prior to adding a new layer of feedstock, thereby improving the quality of the lattice structure due to less cutting and starting of the feedstock.

Abstract: Magnetic modules and a process for manufacturing magnetic modules are provided wherein magnetic material is deposited into one or more cavities patterned into a non-magnetic substrate die to form a plurality of magnetic cores. The patterned substrate board, which may be a composite of graphite, a composite of alumina or other non-magnetic ceramic, provides a surface for winding windows, inductor air gaps, isolations, and a mounting surface for other system components.

Each outlet is connected with an inlet chamber in the atomizer foil via an outlet duct.

Abstract: Percussions instruments, especially drums, consist of a ring-shaped hollow form covered with hide or a resonant skin on the top and bottom. The skins are arranged in such a way that they can vibrate freely. To do this, a flexible tensioning device is used, whereby the tension of said skins can be adjusted by the percussionist during play. A tubular body integrated into the edge of the support in the form of a closed ring-shaped body is thus provided. Said body can be moved towards or away from the hollow form or the outer wall thereof. The tubular ring rests against the percussive ring on the U-shaped supporting edge like a stop and acts upon the edge of the skin. When the periphery of the tubular hose is modified, the described movement and tensioning of the skin occurs.
