Patent CA-2224134-A1 (CA)
Inventor: RADZIK JOSEPH G
IPC: F16L19/08
Filed: 1997-12-09
Abstract: A pipe fitting includes a fixture member having a hollow interior, an outer surface and a pipe opening through the outer surface of the fixture member shaped to encircle a plain end of a pipe. The pipe fitting also includes an engagement member having a cutting surface exposed outside of the fixture member and a threaded attachment member extending outwardly from the outer surface of the fixture member and connecting the engagement member with the fixture member. The threaded attachment member has a central axis extending away from the engagement member, through the outer surface, into the fixture member and generally toward a central axis of the pipe opening. A plain end of a pipe is inserted into the pipe opening of the fixture member and the cutting surface of the engagement member is positioned facing an outer surface of the pipe. The engagement member is moved toward the fixture member along a central axis of the attachment member using the attachment member so that the cutting surface of the engagement member progressively contacts and then cuttingly engages the outer surface of the pipe. Material removed from the outer surface of the pipe is accumulated on the outer surface between the engagement member and the fixture member to thereby form at least part of an interference fit between the pipe and the engagement member.

Title: Method for settling of suspensions with use of seepage force and vibrations
Inventor: TER-STEPANIAN GEORGE
IPC: B01D17/02
Filed: 1998-04-06
Abstract: Impossibility to settle mining tailings in form of hard sediments and forced storage of jelly-like sludge in tailings ponds have a great economic and environmental impact. This feature is caused by undiscovered until present suspension force that decreases the static unit weight of solid particles. Lesser dynamic unit weight is fanned, and solid particles settle extremely slowly. On sufficient concentration of suspension the solid particles become weightless and further settling is ceased. The solid particles remain in equilibrium for indefinite long time.  This force can be destroyed by greater seepage force and dense sediment can be obtained. A  number of auxiliary methods can be used, as vibration for destroying loose structure formed by rigid angular grains, diluting of thick suspensions. for initiating seepage, and applying supplementary hydrostatic pressure into closed container for increasing the hydraulic gradient. The method can be used for purification of impure liquids by settling the impurities.
Patent CA-2230552-A1 (CA)
Inventor: STILBURN JAMES
IPC: G02B1/115
Filed: 1998-02-25
Abstract: A process for forming a two-layer coating on glass or another substrate involves applying first a layer of light metal fluoride on the substrate and subsequently a layer of a porous metal oxide e.g. silica. The metal fluoride layer may be applied by using the sol-gel technique or by other methods e.g. vacuum deposition. The metal oxide layer is preferably applied by a sol-gel technique, by either a dip coating or spin coating. Each layer is preferably about one quarter-wavelength thick. The refractive index of the first layer is lower than that of the substrate, and the second layer has lower refractive index than the first layer. This dependence minimizes reflection of the coating over a broad wavelength range.

Title: Adaptive sports implement
Inventor: ALLEN JONATHAN C
IPC: A63C5/075
Filed: 1996-09-27
Abstract: A sports implement (10) including an electroactive element (22), such as a piezoceramic sheet attached to the implement and a circuit (Figure 3) attached to the electroactive element. The circuit may be a shunt (58), or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement or may simply alter the stiffness to affect performance. In a ski (10), the electroactive element is located near the root (R') in a region of high strain to apply damping, and the element captures between about one and five percent of the strain energy of the ski. The region of high strain may be found by modeling mechanics of the sports implement, or may be located by empirically mapping the strain distribution which occurs during use of the implement. In other embodiments, the electroactive elements may remove resonances, adapt performance to different situations, or enhance handling or comfort of the implement. Other embodiments include striking implements intended to hit a ball in play, such as golf clubs (90) and tennis racquets (100), wherein the strain elements may alter the performance, feel or comfort of the implement.

Title: Method for the compression of recordings of ambient noise, method for the detection of program elements therein, and device therefor
Inventor: BICHSEL MARTIN
IPC: H04H60/37
Filed: 1998-06-22
Abstract: The amount of data produced in the process of recording even short hearing samples by means of a monitor (1) may be considerably reduced by effecting a normalization to a range of values D and a subsequent nonlinear mapping to a second, preferably smaller range of values W. The result may be stored in an electronic memory. Further preferred measures are the spitting of the hearing samples into e.g. 6 signals each of which contains a respective frequency band of the original signal, and the conversion of the original amplitude values into energy variation values with simultaneous low pass filtering. Preferably, all cited processing steps are performed by a signal processor (9). A continuous recording time of up to 14 days by a monitor in the form of a wristwatch can thus be attained with state-of--the-art technology.

Title: Search and rescoring method for a speech recognition system
Inventor: ROBILLARD SERGE
IPC: G10L15/14
Filed: 1998-09-21
Abstract: Speech recognition systems and methods consistent with the present invention process input speech signals organized into a series of frames. The input speechsignal is decimated to select K frames out of every L frames of the input speech signal according to a decimation rate K/L. A first set of model distances is then calculated for each of the K selected frames of the input speech signal, and a Hidden Markov Model (HMM) topology of a first set of models is reduced according to the decimation rate K/L. The system then selects a reduced set of model distances from the computed first set of model distances according to the reduced HMM topology and selects a first plurality of candidate choices for recognition according to the reduced set of model distances. A second set of model distances is computed, using a second set of models, for a second plurality of candidate choices, wherein the second plurality of candidate choices correspond to at least a subset of the first plurality of candidate choices. The second plurality of candidate choices are rescored using the second set of model distances, and a recognition result is selected from the second plurality of candidate choices according to the rescored second plurality of candidate choices.

Abstract: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine.  Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.

Title: Adaptively tuned elastomeric vibration absorber
Inventor: VON FLOTOW ANDREAS H
IPC: F16F7/10
Filed: 1998-12-08
Abstract: An apparatus for reducing vibration has a mount for attaching to a vibrating body, such as the frame of an aircraft.  A plate is spaced from the mount with a mass there between.  A first elastomeric ring is compressed between the mass and the mount, and a second elastomeric ring is compressed between the mass and the plate.  The rings act as a spring having a stiffness that defines a resonant frequency at which the mass oscillates.  Vibration in the body is reduced by the mass movement absorbing vibrational energy and the energy absorption is maximized when the mass resonates at the vibration frequency.  A controller senses body vibration and operates a mechanism that alters the spacing between the mount and the plate thereby adjusting the spring stiffness.  The stiffness of the spring is changed until the resonant frequency of the mass is tuned to the vibration frequency of the body.

Title: Electrical switching apparatus employing interlocks for first and second trip functions
Inventor: MATSKO JOSEPH JACOB
IPC: H02H7/30
Filed: 1999-02-17
Abstract: A circuit breaker includes separable contacts for movement between a closed position and an open position. An operating mechanism, which moves the separable contacts between the closed and open positions, has a closed state and an open or tripped state which corresponds to the open position. A current transformer senses electrical current flowing through the separable contacts as a sensed current. A trip mechanism employs the sensed current for tripping the operating mechanism to the tripped position to move the separable contacts to the open position. The trip mechanism includes a microprocessor which generates short delay and ground fault trip functions of electrical current and time. The microprocessor inputs a first interlock signal from a downstream electrical switching device which generates the first interlock signal with a first value when current through the downstream device exceeds a predetermined value and with a second value otherwise. The microprocessor generates and outputs a second interlock signal to an upstream electrical switching device in response to both of the first and second trip functions. The trip mechanism selectively trips the operating mechanism as a function of the first interlock signal, the first trip function, and the second trip function.
