The container comprises a tubular body member, a bottom member and a top member, with the top member being telescopically received within the body member to seal the top member to the body member. The top member has a closure member that is repositionable to the sealed orientation to substantially reseal the container member.

Abstract: An apparatus for detensioning prestressed strand, the hollow apparatus being capable of movement along a pre-tensioned strand, thus enabling the protrusion of the apparatus's separation device into the rear portion of the strand chuck barrel's inner conical surface. The preferred embodiment of the apparatus is comprised of an outer housing that includes a first aperture large enough to project over the outer surface of the strand chuck barrel, and a second aperture sized to overlap the housing, thus enabling the positioning of the separation device in close proximity to that of the chuck. The apparatus's attraction member induces separation of the chuck from the strand without manual manipulation, thereby enabling detensioning of the strand.

Abstract: A flexible all-steel shaft coupling includes two connecting flanges (1, 2) and an intermediate piece (3, 3′) arranged between the connecting flanges, with a disk ring (4, 5) being arranged between each of the two connecting flanges and the intermediate piece; said disk ring being connected alternately to the respective connecting flange and the intermediate piece, by means of circumferentially-distributed studs (6, 7, 7′) and tension sleeves (8, 9), each comprising a radially protruding end stop, (13, 14), as well as spacer rings (10) held on the tension sleeves, so that the connecting flanges are interconnected so as to be torsionally rigid but with angular movement and axial movement; with each of the studs (6) connected to the connecting flanges being associated with only a single tension sleeve.

Abstract: Vibration decoupler apparatuses, for decoupling vibrations, for example, between first and second the components of an internal combustion engine exhaust system. The flexible connector apparatus is provided for connecting first and second components in the exhaust system, and includes a resilient flexible sealing member (bellows) for accommodating relative movement between the first and second components. The flexible connector apparatus includes an annular vibration damping member connecting a down pipe to a mounting member for permitting restricted axial, lateral and angular movement of the downpipe, relative to the mounting member, which may be affixed to an exhaust manifold, for example. The apparatus also includes a sealing construction which enables weldless, gasketless connection of the bellows. An alternative construction positions the vibration damping member between the decoupler apparatus and the downstream component.

Abstract: An expansion joint for high temperature air or other gaseous flows, of the type in which two duct ends are separated by a gap, that is bridged by overlapping inner and outer liner ducts. The inner and outer liner ducts are surrounded by at least one insulating pillow. The periphery of the expansion joint is surrounded by a flexible cover. A bellows liner structure is disposed between the inner and outer liner ducts and the at least one insulation pillow.

Abstract: An exhaust gas re-circulation system provides for intake of exhaust gases from a first end 206 into one of a plurality of corrugated inner tubes 204 housed within an outer tube 200. Corrugations in said inner tube 204 provide for an increased surface area for heat exchange with a surrounding coolant medium and for decreased velocity of flow of exhaust gas increasing the density of charge of exhaust gas returned to a combustion chamber of an associated internal combustion engine by an inlet manifold where said exhaust gas re-circulation system connects to said inlet manifold at a second end 207. Said outer tube provides for inlet 203 and outlet 202 of coolant medium. Said outer tube further comprises corrugated portions to withstand vibration/expansion. Said inner and outer tubes are manufactured from thin wall metal tubes.

Abstract: A high quality-factor, tunable radio frequency or microwave resonator is disclosed. The resonator includes one or more microelectromechanical switches positioned along its length. The switches are comprised of metal membrane bridges spanning the microstrip resonator. The bridges are connected to radial stubs that comprise reactive loads. An electrostatic potential differential between the bridge and microstrip resonator causes the bridge to collapse, thereby coupling a radial stub to the microstrip. The imposition of the reactive loads on the resonator causes the resonant frequency to change. Multiple resonators employed in a filter configuration can be variably coupled using microelectromechanical bridges that engage or disengage capacitive air gaps between two microstrip lines, to control filter bandwidth over wide tuning ranges.

Abstract: A teething pacifier comprising a pacifier guard having two opposing sides, a nipple and a teething handle. The nipple extends from one side of the pacifier guard, while a connection hub is associated with the opposing side. The teething handle is pivotally connected to the hub, and further includes a first teething material and a second teething material which is at least partially distinct from the first teething material. In one construction, the first teething material is a harder, more rigid material which comprises the handle substrate, and the second teething material is a softer, more compressive material which is overmolded onto the first teething material substrate. In another construction, the softer second teething material forms the handle substrate, and the more rigid first teething material is overmolded onto the second teething material substrate.

Abstract: A dispensing container for fluent material, which container is intended to be hung vertically from a support, such as a hook, is provided. The dispensing container has a tubular body, with a bottom dispensing region that is configured to promote the collection of the fluent material and guidance of the fluent material toward the inlet aperture of a dispensing nozzle that is received in the side of the bottom dispensing region. The dispensing container is preferably fabricated from corrugated paperboard or similar material, and is preferably configured to serve as the shipping container for the fluent material as well, so as to reduce or eliminate the need for a further outer shipping container. The fluent material may be contained within a separate liner structure, within the surrounding tubular body, in a “bag-in-box” type of container arrangement.

Abstract: The invention relates to a device for detecting faults in and/or measuring the wall thickness of continuously moving strips, sections or tubes of plastics, using ultrasonic signals. To this end a number of ultrasonic heads (A, B, C, D) with transmitters and receivers are disposed distributed over the width of the strip or section or the periphery of the tube. The signal, emitted by a transmitter of an ultrasonic measuring head (3) and reflected without scatter, is received by the receiver of said ultrasonic measuring head (3), while the scattered signals reflected on the tube, section or the like are received by the receivers of its adjacent ultrasonic measuring heads (A, B). The inclusion of the scattered and reflected signals in the measurement appreciably increases the measured area per measurement in comparison with using exclusively the signal directly reflected without scatter.

Abstract: A candle construction incorporating a fuel core and a surrounding film having sufficient rigidity and/or stiffness along a vertical direction, to provide support for a fuel core which may be fabricated from a soft, cold-flowing or otherwise non-self-supporting material. The film is preferably fabricated from material(s) that are transparent or translucent, to permit visual inspection of the fuel core, and through the fuel core, if the fuel core is itself transparent or translucent. The film has a softening temperature range, the high end of which is greater than the high end of the melting temperature range of the fuel core material. When the fuel core material is molten and consumed through combustion, the film briefly remains in place to establish a vertical gap to contain the molten fuel material pool. The film may have one or more layers, with different materials and characteristics in the different layers.
