Title: Natural draft portable campfire pit
Inventor: LOPONEN SARAH
IPC: F24B15/00
Filed: 1997-08-26
Abstract: In a campground fireplace, it is common to have a wood-burning device permanently set high on a post, which affords a poor means of warmth and cooking. In this invention, a portable tub fitted with handles presents a more practical and efficient means of generating heat. Perforations along the circumference of the tub provide combustion air by natural draft. A center column may provide a medium for leaning the firewood upright onto it, and can be used to rest the tub at an elevated level by sliding it vertically over a sunken post. An annulus may be fastened to the tub from which a chain may be secured to a tree, a sunken pin, or a post. A removable cooking grille may be placed on the top of the tub. Finally, this device may be fitted with an internal bladder to contain and transport ashes to a disposal site.

Title: Contact arrangement having an auxiliary contact
Inventor: PAULICK THOMAS EUGENE
IPC: H02J7/00
Filed: 1997-08-14
Abstract: A novel contact arrangement enables selective charging of battery packs or the transfer of information between a battery pack and an electronic device. According to one novel feature of the invention, a charging contact (408) is positioned in a region (410) outside of the area covered by the contacts of conventional cells. Therefore, a charging contact terminal of an electronic device will only apply charging current to rechargeable cells to avoid unintentional charging of any primary cells. According to alternate embodiments, battery contacts can be placed at different locations to selectively charge batteries depending upon the battery type. According to other embodiments, information or data transfer contacts (406) can be located at different locations to enable the transfer of information.

Title: Papermaking dryer section with partitioned vacuum box for threading
Inventor: GRUNDER THOMAS K
IPC: F26B13/10
Filed: 1997-09-17
Abstract: A single tier dryer system has dryer rolls with a reversing roll positioned between each pair to transfer and wrap the dryer felt and paper web against the next dryer roll. A vacuum box is positioned between the dryer rolls and over the reversing roll to hold the web on the dryer felt by vacuum. Threading of a tail from the web is accomplished by blowing the web tail off a first dryer roll's surface with a jet of air positioned adjacent to the position on the dryer roll where the dryer felt leaves the dryer roll's surface. The vacuum box is divided by a baffle to isolate a portion of the vacuum box near the front of the dryer rolls, and a damper is positioned within the reversing roll to increase the vacuum in the isolated portion of the vacuum box to facilitate threading of the tail.

Title: Optical fiber probe for position measurement
Inventor: SCHULZ WALDEAN A
IPC: A61B19/00
Filed: 1998-06-04
Abstract: Improved point source electromagnetic radiation emitters including a dispersing element that radiates electromagnetic radiation over a very wide conical angle of approaching about 180°. This light dispersing element can be in any one or more of several illustrated forms such as a light diffusing spherical or hemispherical element, a planar diffusing plate, a tapered light guide, a piano-concave lens, a convex mirror, a light pipe with a large numerical aperture, or the like. The emitter of this invention may be fixed to an object and tracked in a 3-dimensional volume by a system using electro-optical position sensors in order to determine the spatial location of the emitters and therefore to determine, by geometry, the position and orientation of the object. The electromagnetic radiation generator is preferably disposed remote from the emitter and is electrically and magnetically isolated from the emitter. A common optical fiber provides transmission of the radiation from the generator to the emitter. The emitted radiation more nearly resembles point source of radiation and therefore enables more accurate determination of the location of the radiating element, and thereby more accurate determination of the position and orientation of the object on which the emitters reside. The preferred electromagnetic radiation generator is an LED, most preferably a laser diode.
