Title: Optical signal power measurement method and apparatus
Inventor: MASLANEY MICHAEL J
IPC: G01J1/18
Filed: 1987-01-23
Granted: 1992-05-26
Abstract: ABSTRACT   An apparatus and method for measuring power and power losses of light transmissions in fiber optic cables.  The apparatus includes a tester haing a transmitter and a receiver, wherein the transmitter provides at one end of a fiber optic cable a test signal of a known wavelength of light modulated at a known or signature AC frequency.  The receiver detects the transmitted signal at a second end of the cable, determines the modulating frequency of the transmitted signal for identifying the transmitted wavelength of light and measures power of the AC signal.  If measuring the power loss, the receiver further compares the power intensities of the transmitted signal with the power intensity of a stored reference for determining the power loss associated with the transmission of a known wavelength of light.

Title: Method, apparatus and system for recognizing broadcast segments
Inventor: THOMAS WILLIAM L
IPC: G06K9/00
Filed: 1987-04-30
Granted: 1993-10-19
Abstract: METHOD APPARATUS AND SYSTEM FOR RECOGNIZING BROADCAST SEGMENTS     A method, apparatus and system are provided for recognizing broadcast segments, such as commer-cials, in real time by continuous pattern recognition without resorting to cues or codes in the broadcast signal. Each broadcast frame is parametized to yield a digital word and a signature is constructed for segments to be recognized by selecting, in accord-ance with a set of predefined rules, a number of words from among random locations throughout the segment and storing them along with offset infor-mation indicating their relative locations. As a broadcast signal is monitored, it is parametized in the same way and the library of signatures is compared against each digital word and words offset therefrom by the stored offset amounts. A data reduction tech-nique minimized the number of comparisons required while still maintaining a large database.

Title: Arc plasma torch and method using contact starting
Inventor: SANDERS NICHOLAS A
IPC: B23K9/00
Filed: 1988-01-29
Granted: 1992-09-01
Abstract: ARC PLASMA TORCH AND METHOD USING CONTACT STARTING            ABSTRACT OF THE DISCLOSURE         An arc plasma torch includes a moveable cathode and a fixed anode which are automatically separated by the buildup of gas pressure within the torch after a current flow is established between the cathode and the anode.  The gas pressure draws a nontransferred pilot arc to produce a plasma jet.  The torch is thus contact started, not through contact with an external workpiece, but through internal contact of the cathode and anode.        Once the pilot arc is drawn, the torch may be used in the nontransferred mode, or the arc may be easily transferred to a workpiece.  In a preferred embodiment, the cathode has a piston part which slidingly moves within a cylinder when sufficient gas pressure is supplied.  In another embodiment, the torch is a hand-held unit and permits control of current and gas flow with a single control.

Title: Hand-operated low cost magnetic character recognition  system
Inventor: LACAZE JOHN R

Granted: 1993-11-02
Abstract: ABSTRACT A low cost, highly accurate hand operated magnetic character recognition document reader magnetically recognize magnetic ink (MICR) characters imprinted on documents manually conveyed past a magnetic read head.  The reader incorporates the invention described in commonly assigned U.S. Patent No. 4,143,355 to MacIntyre to permit relaxation of the requirement of constant document velocity.  The document is manually conveyed through a defined slotted path so that the characters are scanned by a magnetic read head.  The slotted path is established by pair of substantially parallel (preferably vertical) track members and a bottom wall which is joined to, and separates, the track members by a dimension sufficient to laterally support the document speed is measured during the read operation by an idler member which is freely journaled and thus is drivenly rotated in response to frictional engagement with the conveyed document.  The reader is capable of accurately reading the characters from the document regardless of the direction the document is capable of accurately reading the characters from the document regardless of the direction the document is moved past the read head.  The compactness. low cost, high accuracy and versatility of the reader make it ideal for use in applications where a MICR reader has in the past been impractical -- such as in point of sale and bank teller terminals.

Title: Profiled multi-component fibers and method and apparatus for making same
Inventor: HILLS WILLIAM H
IPC: D01D4/00
Filed: 1988-09-30
Granted: 1993-05-18
Abstract: ABSTRACT   A method and apparatus for extruding a wide variety of plural-component fiber configurations in a spin pack utilizes  one  or  more  disposable  distributor  plates  in which  distributor  flow  paths  are  etched.   The  etching process permits very thin metal plates to be employed, rendering  the  fabrication  expense  for  the  plates  so small,  relative to the remainder of  the spin pack,  as to justify discarding or disposing of the plates rather than  periodically  cleaning  them.   The  etching  process also  permits  the  etched  distribution paths to be  such as to increase the fiber yield per given spinneret surface area.   It  also  permits  the  distribution  paths  to  be sufficiently  small  that  the  resulting  extruded  fiber can  be  made  up  of  at  least  one  hundred  side-by-side sub-fibers.  If the adjacent sub-fibers are weakly bonded, they can be readily separated by agitation to increase the effective yield from the spin pack and provide very fine and uniform fibers.

Abstract: An apparatus for spraying molten thermoplas-tic adhesive in which the outside of a solid stream of adhesive ejected from a nozzle is impacted by atomiz-ing air to form adhesive droplets and the droplets are then directed by pattern-shaping air into a predeter-mined area of a substrate.  The flow rate and velocity of  the  atomizing  air  and  pattern-shaping  air  is independently controlled by separate regulating valves to  permit  variation  of  the  size  of  the  adhesive droplets  formed  and  the  width  of  the  pattern  of droplets deposited on a substrate.  Control valves are provided to sequence the flow of adhesive discharged from the nozzle with the flow of atomizing and pat-tern-shaping air such that the flow of atomizing and pattern-shaping air is initiated before the flow of adhesive from the nozzle begins and after the flow of adhesive therefrom is terminated.
