Title: Method for predicting atherosclerotic risk
Inventor: FOSSEL ERIC T
IPC: G01R33/46
Filed: 1990-12-21
Abstract: A method is disclosed for predicting atherosclerotic risk in a living patient using nuclear magnetic resonance. Specifically, NMR  parameters for protons of high density lipoproteins are determined and compared against a corresponding value for healthy patients. Suppression of the water proton signal is employed where necessary to obtain a suitable spectrum for the non-water component protons. Individuals with high atherosclerotic risk are identified based on the mean normalized high density lipoprotein resonance amplitude of a proton nuclear magnetic resonance spectrum of a chosen body fluid, most typically one's whole blood.

Abstract: ABSTRACT OF THE DISCLOSURE      A reverberatory aluminum melting/holding furnace is formed of an enclosure for containing a molten metal bath in which a workload to be processed is immersed,  a plurality of gas-fired burners for heating the metal bath, and a control system for measuring heat absorbed by the furnace refractory so as to rapidly bring the furnace to  a  pre-set  metal  bath  temperature  without  any significant overshoot.  The enclosure has a wall layer of insulating refractory material disposed on its interior.   The control system includes a first thermocouple element disposed adjacent the "hot face" of the wall layer, and a second thermocouple disposed adjacent the "cold face" of the wall layer.  The plurality of gas-fired burners are switched from a "high fire" to a "low fire"/off condition in response to the temperatures sensed by the first and second thermocouple elements prior to reaching of the pre-set metal bath temperature.  As a result, the heat stored in the refractory is allowed to heat the metal bath up to the pre-set temperature after the plurality of burners have been switched to the "low fire"/off condition.

Filed: 1991-09-10
Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells; abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.

Title: Cargo Loading System
Inventor: PEEPLES FRANK K
IPC: B65G65/32
Filed: 1993-04-07
Abstract: Chip- or plate-like pieces such as wood chips are tightly packed into a ship's hold or other cargo space by directing the material through a pipe to fall by gravity, the pipe guiding the material to rotating paddles.  The paddles engage the pieces of material and propel the pieces away from the paddles along a horizontal path.  The pieces are spread over a wider area, and are given time to fall flat, so the pieces land in the cargo space oriented for dense packing.  The paddles are connected to a center shaft and angle outward to connect to a support ring.          Material is dropped into the center of the support ring to be engaged by the paddles as the assembly rotates.  Material can be limited to the upper, faster, areas of the paddles by a frustoconical diverter disposed centrally of the paddles.  A choke can be used to provide a dense stream of pieces to the paddles; and, the choke may move the stream off center for uneven distribution.
