Abstract: A plastic bag comprises first and second opposing panels, a reclosable zipper, and a slider. The first and second opposing panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth formed opposite the bottom.    The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider from going past the ends of the zipper and to provide adequate end strength that resists stresses applied to the profiles during normal use of the bag, end terminations in the form of posts pass through the male and female tracks adjacent to the ends of the zipper. To retain the posts on the zipper, each of the posts includes enlarged heads at its opposing ends.

Title: A dynamically scaleable conference system
Inventor: CATANZARO ANTHONY JAMES
IPC: H04M3/56
Filed: 1999-03-30
Granted: 2003-10-28
Abstract: A bridging system comprises a router and a number of multipoint servers. For each user requesting to join a particular conference, the router routes the call to a particular server and, if necessary, causes additional servers to be added to increase the capacity for that conference. For example, upon receipt of a user request to join a conference associated with server A, the router first interrogates server A as to current spare capacity. If server A has additional capacity, the router routes the user to server A. However, if server A can not accommodate the user, the router causes server A  to invite an additional server - server B - to join the conference. After server B joins the conference, the router routes the user to server B.

Granted: 2004-09-07
Abstract: An apparatus for communicating, over a single transmission medium, two signals of substantially the same center frequency. The apparatus offsets in frequency one of the signals by combining the signal with the signal from a local oscillator. The apparatus then transmits the two signals, one offset from the other, as well as the signal from the local oscillator to allow for recovery of the two signals with a precise correction for the offset. In particular, the transmission medium is an optical fiber and the two signals are a main RF signal and a diversity RF signal received, respectively, by a main element and a diversity element of a diversity antenna system. The invention is of use, for example, in providing to a microbase station a main RF signal and its diversity RF signal received at a diversity antenna system remote from the microbase station and connected to the microbase station by an optical fiber.

Title: Method and apparatus for harvesting crops
Inventor: PARSON KENNETH ROSS
IPC: A01D41/04
Filed: 2000-06-09
Granted: 2004-02-17
Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff (a mixture of grain kernels, chaff, weed seeds, and other organic matter) from straw (plant stalks), and returning the straw to the field. This is preferably carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and preferably the harvesting unit and vehicle, are designed to make this possible. This avoids difficulties caused by the poor material flow of graff.      Various details of the equipment are also novel.
