Patent CA-2109792-C (CA)
Inventor: FRUS JOHN
IPC: F02P3/05
Filed: 1989-11-02
Granted: 1998-01-20
Abstract: A unipolar ignition of the invention provides a current waveform at the ignitor plug which initially rises relatively slowly, followed by a transition to a fast rising current which quickly peaks and thereafter slowly dissipates.  Such a current waveform provides an initially hotter and longer lasting spark which does not harm the ignitor plug of the system or shorten its life expectancy.  Neither does the spark create stress on the solid state circuitry which delivers the energy to the ignitor plug.  To provide the foregoing spark and current characteristics, an inductor having a saturable core is in series with the ignitor plug, and it provides an initially high inductance which limits the rate of current rise at the plug as energy is transferred from an energy storage device to the plug.  As the current through the inductor increases, its core begins to saturate and the effective inductance begins to decrease, allowing the current to rise more quickly.  As energy is transferred to the ignitor plug, the increasing saturation, decreasing inductance and increasing current complement one another, causing the rate of current rise to increase quickly to a high value desirable for ignition.  Related features of the invention provide for easy diagnostics of the spark and for timing an ignition sequence and providing a repetition rate which aids in a successful ignition.

Title: Illumination system for ophthalmic lens inspection
Inventor: EBEL JAMES A
IPC: G01M11/00
Filed: 1993-12-17
Granted: 2005-02-15
Abstract: A system for providing diffuse illumination in the inspection of ophthalmic lenses for use in conjunction with a computer-based lens inspection apparatus. Below a package containing an ophthalmic lens in deionized water is an optical diffuser made of flashed opal and below that a light source such as a strobe light. The strobe lamp firing is initiated by the image processing system which is in turn triggered by a signal generated by the arrival of a package containing a lens to be inspected. In the preferrerd embodiment, an arc tube is employed wherein light output diminishes by darkening only in one end of the tube, that end placed outside the reflector.

Title: Speech signal encoding system capable of transmitting a speech signal at a low bit rate without carrying out a large volume of calculation
Inventor: TAGUCHI TETSU
IPC: G10L19/113
Filed: 1994-07-06
Granted: 1999-11-09
Abstract: In a speech signal encoding system comprising a maximum similarity series extracting unit (50) for producing a series of excitation pulses appearing at an equidistant time interval and an identical amplitude, the maximum similarity series extracting unit sums up, as a waveform, a series of autocorrelation coefficients to produce a series of summation result coefficients. The autocorrelation coefficients correspond to polarized pulses which are equal to one another in pulse interval and pulse amplitude. The polarized pulses form a plurality of pulse sequences which have phases different from one another. The maximum similarity series extracting unit extracts a polarity of each of the polarized pulses by the use of a dynamic programming method using a degree of an accumulated similarity as an evaluation measure and selects, as the excitation pulse series, one of the pulse sequences which has a maximum waveform similarity between the summation result coefficient series and a series of cross correlation coefficients.

Title: Improved batting practice device using extensible member
Inventor: CIPRIANO RONALD J
IPC: A63B69/00
Filed: 1994-03-21
Granted: 2004-12-07
Abstract: A batting practice device comprising a relatively stiff, elongate tubular member (12) with a handle (14) located on one end and the other end being open and containing in its interior an elongate ball supporting member (18) slidably disposed in a telescopic manner in the interior of the tubular member (12), a ball (28) tightly disposed on the outer end of the ball supporting member (18). The ball supporting member (18) is readily movable between a compacted position in which most of its length is contained in the interior of the tubular member (12), and an extended position in which a relatively small amount of the length remains inside the tubular member. To assort the ball supporting member remaining in the extended position during use, a locking collar (44) is used, which can also be used to retain the ball supporting member in the compacted position. To prevent the ball supporting member from becoming separated during use, a rigid member (60) is extended through the length of the ball supporting member.

Title: Suction feeder
Inventor: MOTOOKA EIJI
IPC: G03B27/60
Filed: 1996-10-02
Granted: 2000-04-18
Abstract: A suction feeder which can feed photosensitive material sheets of different sizes with the suction force applied thereto kept substantially constant.  The suction feeder has a motor-driven endless suction belt having numerous suction holes formed uniformly over the entire area thereof.  A suction box is provided under the carrier side of the suction belt.  It has a belt supporting plate formed with suction holes.  A motor-driven blower is connected to the suction box.  The suction pressure applied to the suction holes of the suction belt through the suction holes in the belt supporting plate is reduced by reducing the revolving speed of the blower-driving motor with increase in the size of the photosensitive material sheet fed onto the carrier side of the suction belt.  It is thus possible to apply substantially constant suction force to photosensitive material sheets of different sizes.

Title: Assembly board with strip conductor fuse and process for operating an electrical circuit arrangement mounted on an assembly board
Inventor: ORTH KLAUS
IPC: H05K1/02
Filed: 1996-11-15
Granted: 2006-06-20
Abstract: The invention concerns an assembly board with electrical conductor strips introduced thereon and with a strip conductor fuse as well as an operating process for a circuit arrangement mounted on an assembly board. The strip conductor fuse (3a, 3c) comprises two conductor strip segments (3a, 3c) through which current passes in opposite directions and these segments are arranged at such a short distance from one another that the magnetic field arising in one conductor strip segment (3a, 3c) through which current passes operates on the electrical charge carriers flowing through the other conductor strip segment (3c, 3a) and vice versa in the case of an electrical short circuit. If an electrical short circuit occurs, the electrical charge carriers of the plasma arising due to the burning off or vaporization of strip conductor fuse (3a, 3c) are reliably removed from the region of the strip conductor fuse due to the interaction with the above-named magnetic fields and thus the short-circuit current is reliably interrupted.

Filed: 1997-04-10
Granted: 2000-07-18
Abstract: Wood is electrostatically coated with a thermosetting powder coating system in which a mixture of a self-curing epoxy resin and a catalyst therefore is extruded and a low temperature curing agent are both pulverized and the powders are blended with conventional additives to make a coating powder which is deposited on a wooden substrate and heated to cure.  The mixture of resin and catalyst does not cure within the extruder but it is made to cure at low temperatures by the separate addition of the curing agent.  A small amount of the low temperature curing agent, insufficient to cause substantial curing during extrusion may be used in place of the catalyst.
