Title: Method for reproducing audio signals and an apparatus therefore
Inventor: NAKAGAWA SHIN
IPC: G10L21/038
Filed: 1995-09-28
Abstract: When reproducing an audio signal in an audio signal reproducing system, the unnaturalness in the quality of the reproduced sound, which is caused by the frequency spectrum of the audio signal is decreased or cut off at an upper limit of the reproducible frequency  or at an upper limit of audible frequency range, is improved, so that a desirable sound in people's audio sense can be reproduced thereby.  This is achieved by adding a random  noise component and/or a higher harmonics component ex-ceeding over the upper limit of the reproducible frequency range or the upper limit of the audible frequency range to the original audio signal in response to an  output of   the   original audio signal. According to the invention, the reproduced sound becomes to have an excellent quality.

Title: Self-hooking ice fishing rig
Inventor: MOLODECKI EDWARD
IPC: A01K97/01
Filed: 1995-11-24
Abstract: A self hooking ice fishing rig includes a base frame, a vertical brace operatively mounted proximal a forward end of the base frame, a catch element disposed proximal a free end of the vertical brace, and a rod having a base end and an line end operatively mountable proximal a rearward end of the base frame.

Title: Remote control video editing system
Inventor: ZAMARA CHRISTOPHER GRANT JOHN
IPC: H04N5/262
Filed: 1996-04-04
Abstract: A video editing system learns the transport characteristics of a source recording medium in a video source deck by instructing a user to provide position information and to respond to commands by manually commanding the video source deck to perform a selected function. The video editing system uses the learned transportcharacteristics to control the movement of the source recording medium by transmitting commands to the video source deck at calculated times. The user inputs data into the video editing system to create an index of segments of data on the source recording medium. The user then selects the order of the segments that are to berecorded onto a destination recording medium in a video receiver. Using the transport characteristics, the video editing system commands the video source deck to move the source recording medium to the beginning of each of the selected segments and to play each such segment. The video receiver is commanded to record each such segment.

Title: Process for Manufacturing Products Made of a Fibre-Reinforced Composite Material
Inventor: VAN HOEY MARC
IPC: B29C48/09
Filed: 1994-12-02
Abstract: In a process that is particularly suitable for producing pipes or hoses, the reinforcing material and the matrix material are no longer produced separately but together in a woven, knitted, braided or non-woven fabric. The matrix material is selected so that its melting temperature is lower than the melting or decomposition temperature of the reinforcing material. The end product is obtained by pultruding the fabricated material, generally designated as textile fabrics, at a temperature above the melting temperature of the matrix material and below the melting or decomposition temperature of the reinforcing material. The product is then cooled to stabilise its final shape.

Title: Closed loop controllable fluid application system
Inventor: PATRICK DENNIS A
IPC: B05C9/04
Filed: 1996-06-06
Abstract: A closed loop controllable fluid application system is  provided,  comprising a substantially  enclosed housing, having horizontal and vertical surfaces, with an inlet and an outlet slot formed in opposing vertical surfaces allowing passage of a work piece through the housing; and a mist outlet and a sump drain each formed in one of a horizontal and a vertical surface.  Fluid circulation lines communicate with the housing and an application fluid source, terminating inside the housing with a connection to one or more controllable spray devices for delivering atomized application fluid to coat passing work pieces.

A method of using this fluid application system comprises the steps of pumping application fluid through the circulation lines to the spray head(s); atomizing application fluid; spraying atomized application fluid onto a work piece; and recycling excess application fluid by evacuating housing air, separating application fluid from evacuated air, and draining fluid through the sump drain.
Patent CA-2181309-A1 (CA)
Inventor: NOTO HIROYUKI
IPC: H02J17/00
Filed: 1996-07-16
Abstract: In a transponder, power supply circuitry is connected to an antenna and a response circuit. DC power to be fed to the response circuit is generated out of an electromagnetic wave come in through the antenna. A rectifier diode has an n type and a p type semiconductor region and is adjusted such that a reverse resistance against a reverse current directed from the n type region toward the p type region is lower than a forward resistance against a forward current directed from the latter region to the former region. A voltage output from the antenna on the receipt of the electromagnetic wave is applied to the rectifier diode, thereby causing a reverse current to flow to the diode. The resulting DC voltage is used to feed power to the response circuit. Even when the electromagnetic wave received from an interrogator is weak, sufficient power can be surely fed to the response circuit.

Patent CA-2184346-A1 (CA)
Inventor: WHITEHOUSE CRAIG M
IPC: H01J49/42
Filed: 1995-02-27
Abstract: A multipole ion guide which begins in one pumping stage and extends continuously into one or more subsequent pumping stages has been incorporated into an atmospheric pressure ion source mass spectrometer system. Ions delivered into vacuum from an electrospray, atmospheric pressure chemical ionization or inductively coupled plasma ion source are guided and focused into a mass analyzer with high efficiency using the multipole ion guide. The background pressure over a portion of the multipole ion guide length is high enough to cause kinetic energy cooling of ions traversing the ion guide length due to ion collisions with neutral background gas molecules. This ion kinetic energy cooling lowers energy spread of ions traversing the multipole ion guide length.   The multipole ion guide DC offset potential can be used to adjust the mean ion energy and the ion guide a and q values can be set to reduce or expand the range of ion mass to charge which will be transmitted through the ion guide.  These features of multipole ion guides and multiple pumping stage multipole ion guides are used to improve performance and lower the cost of atmospheric pressure ion source mass spectrometer instruments.
Patent CA-2185603-A1 (CA)
Inventor: HAWKINS WILLIAM G
IPC: B41J2/05
Filed: 1996-09-16
Abstract: An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.
