  • Patent number: 6446471
    Abstract: The invention is directed to run-free, wholly elastic fabrics. The knitted fabrics of the invention are produced on a warp knitting machine comprising knitting elements including a needle bar and at least two guide bars for stitching in varying proximity to the needle bar. The guide bars are threaded with an elastic yarn. The elastic yarn is knitted together by moving the knitting elements to produce a series of stitches forming the knitted fabric. Advantageously, the method of the invention makes it possible to produce wholly elastic fabrics with high run-resistant properties without knitting the elastic yarn with natural or other synthetic fibers. The invention also relates to wholly elastic warp knitted fabrics comprising an inlaid yarn. The inlay may be an elastomeric or non-elastomeric warp yarn, weft insertion yarn or combination thereof.

  • Patent number: 6439349
    Abstract: The present invention provides a method and apparatus for use in elevator systems for assigning new hall calls to one of a plurality of available elevator cars. According to the invention, a call cost is calculated for each car for accepting the new hall call. The call cost is a function of the estimated time to the desired destination of the passenger requesting the new hall call and of the delay that other passengers who are using the elevator car will experience. In one embodiment, a destination is inferred for the passenger requesting the new hall call. In another embodiment, the passenger requesting the hall call may input a desired destination at the time the hall call request is made. The elevator system of the present invention allows for use of both standard up/down hall call entry devices and destination entry devices that allow a particular destination to be entered by a passenger at the time a hall call is requested.

  • Patent number: 6427575
    Abstract: A jacket-assembly is sealed to a hydraulic elevator jack to protect the jack from corrosion. The jacket-assembly is preferably manufactured from a non-galvanic, non-corrosive material, such as high density polyethylene tubing. The jacket may be manufactured from any non-galvanic, non-corrosive material that is strong enough and flexible enough to be factory-installed on the jack. The jacket is preferably hermetically sealed to the jack. The jacket-assembly may contain a bulkhead mounted on the hydraulic elevator jack having an O-ring groove. An O-ring can be used to effect a hermetic seal between the bulkhead and the jacket. The bulkhead may be mounted on the jack with any conventional means, such as a weld. In one embodiment, a moisture sensor may be placed inside the jacket.

  • Patent number: 6428561
    Abstract: Use of one or more saccharides, for example one or more non-toxic mono-, di-, tri-, oligo- or polysaccharides, in the manufacture of a biocompatible glue for adhering a first structure to a surface of a second structure. The biocompatible glue can be adapted to act as a temporary glue. In this case the glue may be used to enable a medical structure to be transferred from a medical instrument onto the surface of a structure of a human or animal body, for example as in the transfer of a buffer material from the fork of a surgical stapler to a diseased lung after one or more rows of staples have been fired through the buffer material into the lung during lung volume reduction surgery for treating emphysema. The biocompatible glue can also to advantage be used to adhere or secure medical structures to a structure of a human or animal body direct, such as in the case of a patch being applied to the skin of a mammal.

  • Patent number: 6425821
    Abstract: A fluid diffuser and a method for diffusing fluid are provided. In one preferred embodiment, the diffuser comprises a frame adapted to be connected to the end of fluid supply duct. Mounted within the frame is a pore-containing web. The web redirects fluid passing through the pores by changing the direction of the fluid upon exiting the web. Prescribed portions of the web can be blocked to expel fluid preferentially in one direction and expel fluid less in other directions. Other means for controlling the direction and flow of fluid upon exiting the web are provided, including changing the angle of fluid supply to the web, and placing a vane at the entrance to the web.

  • Patent number: 6414141
    Abstract: Applicants have developed a process for purifying an ampicillin pro-drug ester, e.g., bacampicillin, or an acid addition salt thereof of formula I. The process comprises a step wherein a crude solution of the pro-drug ester is subjected to an evaporation which is controlled by the evaporation rate of the organic solvent such that a continuous operation is accomplished for the crystallization of the desired purified pro-drug ester or salt thereof. Said crystallization is preferably preceded by an aqueous phase extraction and/or an organic phase extraction, both preferably also being performed continuously.
