Patent number: 6313374Abstract: A process for effectively remediating soils contaminated with individual or mixture of metal ions is described. The process involves utilizing plants of the genus Pelargonium, particularly Pelargonium sp., to hyperaccumulate metal ions in their roots and shoots. These plants when grown on soils, which contain one or more of the metal ions, individually or in a complex mixture, will uptake the metal ions through their roots and translocate them to the shoots. This process thereby removes the metal ions from the soil. The harvested shoot and root biomass can be used for extraction of essential aromatic oils, and the residual oil-extracted biomass will be available for extraction and recycling of the metals. The process also describes the use of the above said plant(s) for remediating land-farming sites of petroleum industries, which are generally contaminated with a mixture of metal ions and organic contaminants.Type: GrantFiled: November 4, 1998Date of Patent: November 6, 2001Assignee: University of GuelphInventors: Sankaran KrishnaRaj, Praveen K.

Patent number: 6313399Abstract: For cooling an encased electric device (100) by means of the convection flow of a medium, a cooling element (400) is attached to device (100), said cooling element includes a back plate and ribs (401) fastened to device (100) at certain distances. The width of at feast one space (402) between the ribs is different at different points. The width of the spaces (402) between the ribs is at the widest at the points of the cooling element which, in the intended position of use of the cooling element, are downwards and/or sidewards, and at the narrowest at the points of the cooling element at which the electric device (100) contains a component that produces a lot of heat during use.Type: GrantFiled: August 14, 2000Date of Patent: November 6, 2001Assignee: Muuntolaite OyInventors: Teuvo Suntio, Jarmo Mäki

Patent number: 6313400Abstract: A PC or CF (Compact Flash) card housing has housing halves (32, 34) that each includes a sheet metal shield (50, 70) with a main wall lying in a horizontal plane and with primarily vertical side walls (56, 58, 72, 74), with the side walls of the housing halves overlapping when the housing halves are assembled together. Each shield side wall includes dimples (90, 106) formed by deforming out areas of the sheet metal shield side wall. Each dimple has opposite faces respectively forming a recess and a projection. The recesses (108) of the top housing side walls receive projections (94) of the bottom housing side walls to lock the housing halves together when one is pushed vertically into the other. The dimples have opposite sides (140, 142) connected by bends to surrounding sheet metal, and have lower ends (130, 144) severed from surrounding sheet metal.Type: GrantFiled: July 13, 1999Date of Patent: November 6, 2001Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Rene Augusto Mosquera, Terry Lee Adams, Del Wood

Patent number: 6313401Abstract: A singly or doubly encapsulated actuator/sensor package in which a ceramic actuator/sensor (10) may be first encapsulated in a primary encapsulating material (12) and is encapsulated in a fiber-reinforced composite material (20, 22). A combination of the material and ply angles (&thgr;) of the fiber-reinforced composite material (20, 22) are used to control selection of a composite coefficient of thermal expansion (CTE) and the stiffness or compliance of the package with respect to a selected axis. By optimal selection of the material and the ply angle, based upon a suitable actuation strength figure of merit, a CTE of zero or a CTE matching that of an underlying structural member (24) is obtained, while simultaneously maximizing the actuation strength in a selected actuation direction.Type: GrantFiled: December 18, 1998Date of Patent: November 6, 2001Assignee: TRW Inc.Inventors: Michael J. Triller, Christopher W. Felts, Kathleen M. Doherty, Lisa R. Hill, Craig A. Lavinsky

Patent number: 6313402Abstract: A metallic or an electrical trace having a terminus and a stress relief bend formed in the trace adjacent the terminus. The electrical trace may have a portion carried by a flexible substrate to form a flexible circuit. The stress relief bend may be free floating and extend from the flexible substrate or may be encapsulated by the flexible substrate. The electrical circuit and the flexible circuit each have a generally planar portion extending in the X and Y axis, with the stress relief bend projecting into the Z axis. This allows electrical traces to be spaced with a very narrow pitch because the stress relief bend does not consume any valuable real estate on the flexible circuit or the substrate to which the electrical trace is applied.Type: GrantFiled: October 29, 1997Date of Patent: November 6, 2001Assignee: Packard Hughes Interconnect CompanyInventors: Chris M. Schreiber, Bao Le, Eric Dean Jensen

Patent number: 6313404Abstract: A box structure for electric switches provided with an opening to allow assembling of the requisite parts for the switch in the body, wherein, two engaging grooves are provided respectively on the two external lateral sides of the body, the engaging grooves cooperate with engaging portions provided on engaging pieces having engaging lobes integrally connected therewith. The engaging pieces are made of material with better resiliency than that for the body. The engaging lobes have beveled surfaces that are coarse surfaces in order to make firm connection after the box structure is engaged in a switch receiving seat. The box structure is different from that of conventional box structures in the mode of assembling, a user can individually change the damaged parts by detaching and reassembling, especially the lobes and their related parts in the box structure which have the largest damage rate. In this way, money can be saved, and the requirement of the environmental protection can be satisfied.Type: GrantFiled: March 1, 2000Date of Patent: November 6, 2001Inventor: Tsung-Mou Yu

Patent number: 6313405Abstract: A cable tray including a pair of generally parallel or concentric spaced-apart metal side rails and a plurality of spaced apart rungs secured to and extending between the rails at intervals spaced along the rails. The rails and rungs define a cable fill area therebetween. The spacing of the rungs is set according to a pi spacing factor. The rails can have laterally projecting top flange members that extend outwardly in a direction away from the cable fill area and can have lower flange members that extend inwardly in a direction into the cable fill area. The top flanges have a plurality of spaced apart apertures therethrough.Type: GrantFiled: August 31, 1999Date of Patent: November 6, 2001Assignee: Cooper Technologies CompanyInventor: Eric R. Rinderer

Patent number: 6313406Abstract: An integral or unitary flexible cable support having: 1) a base for mounting on an appropriate structural member, and 2) a flexible strap integrally formed with the base, the flexible strap having a base end attached to the base and a distal end that includes a key hole shaped aperture for engaging an appropriate attachment button on the front of the base. In use, cable or wiring to be supported is placed within the flexible strap, the strap bent to encompass the wiring and the keyhole shaped aperture engaged about the attachment button. This provides a wiring support that is not easily disengaged by random movement of the wiring, but is easily disengaged by hand for removal of one or more cables or insertion of additional cables by proper alignment of the key hole shaped aperture with the attachment button.Type: GrantFiled: February 16, 2000Date of Patent: November 6, 2001Assignee: Arlington Industries, Inc.Inventor: Thomas J.
