Abstract: A device for sensing electric discharges in a test object (1) with at least two electric connection conductors (1a, 1b, 1c, 1d) comprises transducer equipment and evaluation equipment (PA, ABU, LU). The transducer equipment comprises at least one transducer (6a, 6b, 6c, 6d) for direction-sensitive sensing of current pulses through the connection conductors by sensing a magnetic field, generated by the current pulses, and the polarity thereof. The transducer delivers a transducer signal (v1", v2", v3", v4", v11", v21") to the evaluation equipment in dependence on said current pulses and their direction. The evaluation equipment generates, in dependence on received transducer signals, an indicating signal (IND) indicating an electric discharge in the test object.

Title: Coating strip material with protective/decorative layers while avoiding use of solvents
Inventor: INNES ROBERT A
IPC: B05C11/10
Filed: 1995-11-23
Granted: 2001-01-23
Abstract: A process and apparatus for coating a surface of an elongated strip article, e.g. aluminum sheet, with a layer of solid polymer material. The process involves heating the polymer to produce a melt having a viscosity of at least 1000 centipoise when measured according to ASTM D4440 at 1 radian per second, extruding the melt onto a moving surface of the strip article through an elongated slot in a coating head having an extended surface adjacent to the slot arranged at an angle to the moving surface to form a coating gap converging in the direction of movement, thereby forming a coating on the strip article, and pushing the coating head towards the surface of the strip article as the melt is extruded as the coating onto the surface from the slot to reduce the coating thickness to a desired range by pressing the extended surface of the coating head onto the coating as the coating is formed. The apparatus includes coating heat, provided with a heater to maintain the viscosity of the melt, and load application device for the coating head, as well as means for melting the polymer and supplying the melt under pressure and at the desired temperature to the coating head. The process and apparatus allows strip articles to be coated with thin (1-100 microns) coatings of polymer materials without employing liquids as solvents or the like that cause atmospheric pollution problems.

Abstract: An RF transponder system is provided that is capable of detecting and correctingdata transmission errors. The RF transponder system includes an exciter that generates an RF excitation signal and a transponder that receives the RF excitation signal and is powered thereby. The transponder generates and transmits a RF response signal including a plurality of data sets each containing a common message. At least one of the data sets is encoded in a manner different from the remaining data sets. The RF response signal is received by a reader that decodes the encoded data sets. Corresponding bits of each of the data sets are compared for purposes of error detection. If a majority of corresponding bits from each of the data sets match, a valid bit is defined thereby. Bits that are not in the majority are discarded. An invalid bit is defined where less than a majority of corresponding bits match a selected bit of a selected data set.

Title: Navigation among grouped television channels
Inventor: EYER MARK K
IPC: H04N7/16
Filed: 1997-12-16
Granted: 2005-05-03
Abstract: A television viewer can easily navigate programs which are grouped according to a common service provider or other grouping criteria by depressing the "channel up" or "channel down" buttons on a hand-held remote control. Programming services which are provided via one or more transmission paths are integrated, thereby allowing a viewer to successively select the grouped channels regardless of the broadcast signal, transmission path, frequency spectrum, transport stream and/or PID in which the channel is carried. Data is provided with broadcast signals to indicate broadcast address information which corresponds to a primary channel and one or more secondary channels of a channel group. A viewer can successively view the channels of the group while bypassing intermediate non-group channels. Grouped channels can thus be designated by a common channel designator such as a channel number. Goodwill and brand loyalty which has been built up over time in a local station channel number can be used to define a family of programs to maintain continuity as channels are added or dropped, or channel assignments of programming services are rearranged.

Abstract: The dispenser device of the invention comprises a liquid storage tank overlying an intermediate chamber partially filled with liquid. The top storage tank is fluidingly linked to the intermediate chamber, and a first valve controls the liquid flow under the gravity force from the top tank into the intermediate chamber. The intermediate chamber comprises on its bottom wall an outlet port for allowing liquid to be dispensed therethrough under the gravity force and under the pressure of the overlying liquid, the liquid flow through the chamber outlet port being controlled by a second valve. A small computer is linked to the first and second valves and to a float gauge floating on the liquid located inside the intermediate chamber. Thus, the computer detects by means of the float gauge any variation of the level of liquid inside the intermediate chamber. In use, the data concerning the precise quantity of liquid which is desired is entered into the computer. The computer sends a signal to the second valve to allow liquid flow during a precise time period out of the intermediate chamber, this liquid being collected in a suitable receptacle. To be certain that the quantity of liquid dispensed through the second valve is precise, the height of the liquid inside the intermediate chamber is maintained constant, so that the pressure applied on the outflowing liquid by the overlying liquid remain constant. This is accomplished by a signal, through the computer, of the float gauge to the first valve to allow liquid refill from the tank into the chamber.

Title: Synthetic protein folding catalysis
Inventor: RAINES RONALD T
IPC: A61K31/00
Filed: 1997-07-09
Granted: 2004-05-25
Abstract: An analysis of the protein folding characteristics of the eukaryotic protein folding enzyme protein disulfide isomerase (PDI) led to a study of the minimally sufficient motif for catalytic activity of that enzyme as well as the prokaryotic enzyme thioredoxin. Based on such study, a model for this catalytic activity was developed which was used to predict what non-protein catalysts might substitute for this enzymatic activity. Based on this analysis, it was predicted that a small molecular weight dithiol molecule having a pK a of less than about 8.0 and an E~' of more than about-0.25V could catalyze the formation of proper disulfide bonds in a eukaryotic protein. Subsequently, it was verified that such a dithiol, such as the exemplary molecule BMC, is capable of catalyzing the proper formation of disulfide bonds, and the proper folding of proteins, both in vivo and in vitro. This permits a small organic molecule to be substituted for an enzymatic system in protein synthesis.
