Title: Light reflecting defect detention apparatus and method using pulsed light-emitting semiconductor devices of different wavelengths
Inventor: NYLUND STEVEN L
IPC: G01N21/89
Filed: 1989-11-10
Granted: 1999-09-28
Abstract: A light-reflection defect detection apparatus and method for sensing the presence of food products or other articles and detecting defects therein is described using pulsed light-emitting semiconductor devices, such as light-emitting diodes (LEDs). The LEDs emit at least three different wavelengths of light including two of visible light (i.e., red and green light) and one of infrared light. Viewers each including a photosensor, such as a photoelectric detector, are employed to sense the light reflected from the article and to produce sensor output signals which are sampled and stored before being transmitted to a digital computer for signal processing. The groups of LEDs are pulsed ON and OFF by a capacitor discharge pulse generator circuit which causes a substantially constant current to flow through the LEDs so that they emit light of uniform intensity. The defect detection apparatus and method is especially useful in detecting defects in elongated food products such as French-fry potato strips.

Title: Long feature vertical or horizontal electrical conductor detection methodology using phase coherent electromagnetic instrumentation
Inventor: STOLARCZYK LARRY G
IPC: G01V13/00
Filed: 1991-01-04
Granted: 1995-06-13
Abstract: A method utilized with an underground conductor detection system for calibrating a downhole transmitter to compensate for detuning of the transmitter antenna by geologic formations.  The method comprises sending a synchronization signal to the transmitter antenna, measuring the current flow through the transmitter antenna and adjusting the current to a constant level, and measuring the phase difference between the transmitter antenna current and the synchronization signal.  A receiver transmitter is calibrated by sending a synchronization signal to a radiating antenna in the receiver that in turn sends a calibration signal to the receiver antenna that is directed over the entire signal pathway back to surface located signal processing equipment.  Another method of underground conductor detection sends a surface wave to the downhole receiver to cancel the effect of the surface wave modulation on a target wave being radiated by the underground detector.          Another method of underground conductor detection utilizes a receiver tuned loop antenna oriented orthogonal to the magnetic dipole of the transmitter antenna for discriminating against reception of a primary wave.  Another method of detecting anomalous geological zones such as tunnels, utilizes a low to medium frequency tomographic scan to cancel the effect of geological conductivity noise in a high to very high frequency tomographic scan of a region suspected of containing the anomalous geological zone.

Abstract: Allowing a shared line appearance feature to be implemented on a plurality of telephone station sets which are connected to different telecommunication switching systems. The telecommunication switching systems can be interconnected to each other via the public telephone network utilizing standard telecommunication links. A software application program provides a termination point for a directory number that is associated with a shared line appearance. The software application program receives all incoming calls directed to the directory number and determines the operations that should be performed with respect to the telephone station sets terminating the shared line appearance. The software application program directs the incoming calls to the telephone stations sets regardless to which telecommunication system each of the telephone station sets is interconnected. An outgoing call from one of the telephone station sets is switched to the software application program which then switches the outgoing call to thedestination telephone terminal as if the outgoing call had originated at the location of the software application program. With respect to the outgoing call, the software application program also transmits messages to the other telephone station sets terminating the shared line appearance, so that those telephone station sets canindicate that the shared line appearance is busy.

Title: Method and apparatus for making cellulosic fibrous structures by selectively obturated drainage and cellulosic fibrous structures produced thereby
Inventor: TROKHAN PAUL DENNIS
IPC: D21F11/00
Filed: 1992-06-17
Granted: 1997-01-14
Abstract: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with dif-ferent flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.
