摘要:
The invention includes linkage assemblies comprising coupled links with metallic contact surfaces with improved stiffness. The inventors found significant mechanical problems with all previous descriptions of metallic contact links sufficient to preclude their commercial use. These metallic contact links are a significant improvement over existing plastic ball and metal joint, or all plastic beads as found in the prior art. The invention includes methods providing these links and high friction couplings between them, as well as the linkage assemblies and flexible arms resulting from these processes.

The present invention relates to a one-step fastening device, a process for creating a fastener utilizing such a device, and the end fastener produced thereby. In this regard, the invention uses an outer, hollow fastener material that can be partially compressed under tension at designated areas (i.e., a compression member) and an inner activation or tensioning member. The compression of the outer fastener material occurs at one or more flexible areas or compression features specifically located on the longitudinal axis of the material. As a result, the outer compression member is capable of being distorted or bent under tension to produce a predetermined configuration. The device described herein has the ability to form specific and controllable fasteners of designated shapes and configurations. Methods for fastening, snaring, gripping, cutting, and manipulating material using the device in a confined space are also provided.

A thermal treatment system for supplying thermally conditioned or purified water for human or animal consumption, industrial processes, environmental containment, or removal of foreign species. The water purifier includes a heat exchanger for exchanging heat between outgoing thermally conditioned or purified water and incoming makeup water; a water heater is connected to the heat exchanger so as to receive pre-heated incoming makeup water, where the water heater subsequently heats the incoming preheated makeup water to a set-point temperature in the case of thermally conditioned water and for purified water also holds the water for a period of time sufficient to inactivate selected organisms to a predetermined level. The heat exchanger has one or more treated water outlets for supplying thermally conditioned or purified water at selected temperatures.

Machinery for automated manufacture of formed wire structures such as innerspring assemblies for mattresses and seating and flexible support structures includes one or more coil formation devices configurable to produce helical spring coils having a terminal convolution which extends beyond an end of the coil; a conveyor system having a plurality of flights slidably mounted upon a continuous track and connected to a chain and driven by an index driver, the flights being connected to a drive system which enables variable spacing between the flights so that the conveyor can be loaded with articles at one spacing interval and be unloaded at a different interval; a coil transfer machine which removes a row of coils from the conveyor and inserts the coils into an innerspring assembler; an innerspring assembler having first and second sets of coil-engaging dies in a parallel arrangement, each set of dies having an upper row positioned over a lower row, the dies being mounted upon carrier bars which are vertically translated within the innerspring assembler to diverge the upper and lower dies of a set to allow positioning of a row of uncompressed coils between the upper and lower dies, and to converge the upper and lower dies upon a row of coils to compress and thereby securely hold the coils in a row; a coil interconnection device for interconnecting adjacent rows of coils in the first and second sets of dies by attachment of fastening means about the adjacent coils; and an indexer assembly engageable with the carrier bars and operative to laterally translate the carrier bars, whereby the lateral position of the first and second sets of dies can be exchanged to provide continuous attachment of rows of coils to produce an interconnected array of coils as an innerspring assembly.

The apparatus for applying granules to a coated asphalt sheet has a nozzle for holding an accumulation of granules, an opening at the bottom of the nozzle for discharging the granules onto the coated asphalt sheet, a buffer chamber positioned in communication with the accumulation of granules, and a vacuum source for reducing the pressure in the buffer chamber to stop the flow of granules through the opening.

Tube and float systems for separation and axial expansion of the buffy coat are provided. Generally, the systems include a flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The sample tube has an elongated sidewall having a first cross-sectional inner diameter. The float has a main body portion and one or more support members protruding from the main body portion to engage and support the sidewall of the sample tube. During centrifugation, the centrifugal force enlarges the diameter of the tube to permit density-based axial movement of the float in the tube. After centrifugation is ended, the tube sidewall returns to its first diameter, thereby capturing the float and trapping the buffy coat constituents in an annular volume. Several different systems for capturing and retrieving the buffy coat constituents are described.

There is provided a device that retains a collected sample for on-demand testing of a small portion of the collected sample while the rest of the sample remains for optional additional analysis. The on-demand test provides relatively immediate information about aspects of the sample, e.g. presence of microbes, chemistry, nutritional condition, presence of contaminants.
