Abstract: An improved tape supply system particularly suited for use in a multifunction tape applicator for applying a front and/or back L-clips to a case wherein a dancer roll is operable to provide slack in the tape and a break is applied to facilitate cutting of the tape.

Abstract: The invention relates to a needle guidance system provided by a needle with a steerable tip. The needle has a cannula and a stylet. The stylet adjacent to its tip has a naturally curved portion. The stylet is movable in two degrees of freedom with respect to the cannula—axial translation and axial rotation with respect to the cannula axis. When extended, the stylet curves off-axis and provides cannula tip steering. Driving and/or steering systems may be provided to the orientation and relatively move the stylet.

Abstract: A signaling system for detecting power line discontinuity in a power distribution system having a local power generator in a feeder line employs a signal generator that provides a local generator control signal with a preset protocol continuously and is located in the power distribution system upstream of said local power generator. A power detector terminates the local generator control signal and a signal detector in said feeder line detects the presence of the signal and triggers the shutdown of the local generator when the signal is not detected by the signal detector for a predefined period of time.

Abstract: A personal flotation device is formed with a neck opening defined by a plurality of discrete lobes projecting in toward the inside of said neck opening and including a chin lobe that is positioned to engage the underside of the chin of a user when device is in operative position on said user and inhibit removal of said device over the head of the user. The chin lobe is spaced from adjacent portions of adjacent said lobes to provide spaces therebetween to facilitate donning and doffing of said device when said chin is aligned with one of the spaces. The device is also preferably provided with cover panels that releasably connect together around their peripheries so that the edges of the bladder contained between the cover panels may be folded and retained in folded position when the sides of the over panels are connected.

Abstract: A compact four degrees of freedom parallel mechanism suitable for use as a hand control or wrist is provided that has backdrivability, is singularity free and has a large workspace and a large force reflecting capability. The structure is light but rigid, and the electric actuators are all placed on the ground or base and provide independent control of each degree of freedom. Each degree of freedom is connected to an actuator either directly or through a cable drive system. The first two degrees of freedom are created by two identical pantographs pivoted together on pivoted joints to define a hemispherical motion of an object (end point) about a center point (hemisphere center). The third and fourth degrees of freedom represent rotation and sliding motions of the object around and along the radius of the created hemisphere, respectively. The axes of these latter degrees of freedom are concentric, and these axes intersect with the axis of the pantographs pivoted joints at the hemispheric center.

Abstract: A buoyancy device has a rear buoyancy area interconnected to a pair of lateral under arm buoyancy areas by a pair of front buoyancy areas, and combining to form a simulated W-shape when viewed in a plan view. The provision of the lateral or underarm buoyancy areas function to hold the user more upright and normally higher above the level of the water when in use.

Abstract: A the operation of pulp screening apparatus may be improved by employing a multi element foil having a leading foil section and a trailing foil section spaced from and trailing leading section so that adjacent surfaces of the sections one formed by a portion of a pressure side of the leading section and the other by the leading end of the trailing foil section define opposed walls of a passage for fluid directing fluid flow from the pressure side of the leading foil section to a cambered low pressure side of the trailing section. The angle of attack (?) of the complete multi element foil is set to be significantly less than the angle of attack (?) of the trailing foil section to increase the negative pressure pulse generated by the trailing section and thereby improve operation of the screening device.

Abstract: A releasable slide fastener closure is formed by a pair of stringers with elements that interlock when in cooperating closed position and a slider mounted on the stringers for sliding movement along said stringers to move the elements into said interlocking closed position on movement in of the slider away from a first end and toward a second or closed end. Each of the stringers has a stop for preventing said slider from separating there from at each of its ends and the stringers are free to separate from closed position at the first end when a force is applied in a predefined direction adjacent to the first end.

Abstract: A method of producing a strand board having an average density of between 450 and 550 Km/m3 by providing a first set of strands having a moisture content of between 25 and 45% based on the dry weight of said strands and a second set of strand having a moisture content of between 5 and 7% based on the dry weight of said strands and forming a lay-up having a core layer formed of strands from the second set of strands sandwiched between a pair of surfaces layers each formed from strands of the first set. The lay-up is then pressed between heated platens into a consolidated panel having an average density of between 450 and 550 Km/m3 by closing the platens to the thickness of said consolidated panel in less than 30 seconds and raising temperature the said core layer to 100° C. in less than 35 seconds without increasing the core gas pressure above 0.17 MPa.

Abstract: A process for recovering fine coals and clarifying water for recycling features with three distinct mechanisms: hydrophobic extraction, electrolyte coagulation, and macromolecular flocculation, which if desired may be integrated into a single stage. The hydrophobic extraction is accomplished using oil to form a coal-in-oil mixture. The process water is clarified using a flocculants, more preferably a combination of coagulant and anionic flocculants. With a well defined reagent addition scheme, this process allows a combustible recovery greater than 88% at an ash content less than 11%, while producing a clean water containing less than 20 ppm suspended solids from a tailing's stream. The coal-in-oil mixture may be used as a fuel for example in coal-firing boilers and power generators.

Abstract: A pressure-applying garment particularly suited for locating and applying pressure to transmitters is formed by a main inflatable bladder inflated to first pressure to press its inner wall toward a wearer and conform the inner wall to contours of said wearer and to apply the desired pressure between the wearer and a transmitter interposed between the main bladder and the wearer. A plurality of auxiliary inflatable bladders positioned relative to the main bladder and oriented to having their inner walls facing toward said wearer. The auxiliary bladders are provided with separate inflating systems so that at least some of said auxiliary bladders are inflated to a selected pressure different from (higher than) the first pressure to deform inner wall of its auxiliary bladder to conform with and press towards adjacent portions of said wearer and preferably to apply the desired pressure between the wearer and a transmitter interposed between the auxiliary bladder and the wearer.

Abstract: A method and apparatus for squaring knocked down slotted boxes employs an L-shaped support and forming platform onto which a partially opened box is applied so that the junction of the two legs of the L-shape is received within the box and a leading flap (and its fold line connection to the box) and a trailing flap (and its fold line connection to the box) each contact one of the legs to fold these flaps outward and tend to square the box. The trailing flap is moved from one leg onto the other which normally will be substantially flat and horizontal so that the leading and trailing flaps are folded perpendicular to the axis of the sleeve portion of the box while the side flaps positioned between the leading and trailing flaps remain in the plane of their respective box wall as the carton is moved into an operating station.

Abstract: A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.

Abstract: An anti-G pressure garment system incorporates an inflatable pressure bladder covering portions of the wearer's body. The bladder is provided with an area made of a first material formed by a flexible air and liquid impermeable, vapor permeable, micro-porous material that facilitates the passage of water vapor therethrough whereby pressurized gas will be retained by the said bladder and water vapor adjacent said inside layer will pass through said material into the interior of the bladder. The bladder also includes a second area made of liquid impermeable, air and water vapor permeable material so that the second area permits a preselected amount of controlled leakage from the bladder to the wearer while maintaining adequate pressure in the bladder.

Abstract: A method and/or apparatus for measuring current in a high voltage (HV) current carrier generates a low voltage signal proportional to the current in the HV carrier and applies this signal to an integrated-optic voltage sensor located in the HV environment adjacent to the HV current carrier to produce a modulated optical signal representative of the current being measured. The optical signal from the integrated-optic voltage sensor is conducted to a low voltage (LV) environment insulated from said HV environment and processed to provide a second electrical signal. One of the electrical signals is integrated so that an output signal of the required accuracy is available form the system.

Abstract: A disk probe velocimeter is formed by multiple orthogonal disks fitted with pressure transducers positioned to measure dynamic pressure differences between the center of one disk face and the center of the other face of each disk. The velocimeter can measure reasonably accurately three components of velocity where the approximate direction of the flow is not known. Where the dominant velocity component is known, the velocimeter may be combined with a Pitot probe to form a compact anemometer.
