Title: Process for the Reactivation of Nickel-Alumina Catalysts
Inventor: CLAVENNA LEROY R
IPC: B01J23/94
Filed: 1994-04-22
Abstract: A process for the reactivation, or rejuvenation of a nickel-alumina catalyst employed in the production of a gas comprised of an admixture of hydrogen and carbon monoxide, or synthesis gas, by the conversion, in a reactor, or reaction zone, of light hydrocarbons in a fluidized bed of the catalyst at elevated temperature, in the presence of steam and oxygen. Catalyst reactivation is accomplished by with-drawing a portion of the catalyst from the fluidized bed of the reactor and treating the catalyst in an oxidation zone at temperature sufficient to oxidize and convert the nickel component of the catalyst to nickel aluminate and disperse said nickel aluminate within the alumina support, and then recycling the treated catalyst to the reactor, or reaction zone, to reactivate and increase the activity of the catalyst. The catalyst, on reduction in the reactor, or reaction zone, is provided an additional boost in activity by washing, treating or contacting the catalyst from the elevated temperature oxidation zone with an acid sufficient to remove trace impurities without removing any substantial amount of the nickel aluminate, and without forming a residue on the catalyst surface. The normal tendency of the catalyst to agglomerate at reaction conditions is.also reduced by the acid treatment.

Title: Detonator primer capsule
Inventor: BOWN ARTHUR F
IPC: F42B3/16
Filed: 1994-05-10
Abstract: ABSTRACT                  DETONATOR PRIMER CAPSULE  A detonator for detonation of explosives which provides protection of a primer charge from sympathetic initiation and provides efficient detonation of a base charge.  The detonator is comprised of, a hollow detonator shell having first and second ends, said detonator shell has inserted therein a delay element and a primer capsule. Said delay element is positioned within the first end of the shell and has a core running therethrough.  The primer capsule has a protective frustrum top having an opening centrally located therein and a tubular bottom.  The primer capsule is inserted into the second end of the shell such that the core of the delay element is in contact with the opening in the frustrum top.  The primer capsule top contains a primer charge and the bottom contains primer charge and a small amount of base charge material.  The top is constructed with heavy walls such that the primer charge is protected.  Further, the top is constructed such that upon initiation of the primer charge by the delay element the output of the primer charge is focused toward the base charge material which when initiated initiates an external base charge.  The primer capsule construction provides a system wherein the primer charge reaches full velocity and shock by the time it reaches the small amount of base charge material and thus provides more efficient initiation.

Title: Computational complexity reduction during frame erasure or packet loss
Inventor: CHEN JUIN-HWEY
IPC: H04B14/04
Filed: 1995-02-13
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech.  During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only.  This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Patent CA-2144552-A1 (CA)
Title: Optical fiber gyro
Inventor: KUMAGAI TATSUYA
IPC: G01C19/72
Filed: 1995-03-14
Abstract: A photodetector generates an electric signal by receiving a light signal which is obtained by coupling light streams, propagated through an optical fiber sensing loop in clock-wise and counter clock-wise directions and modulated in a phase modulator.      The electric signal is detected in a synchronous detection circuit to generate a fundamental wave component of the phase modulation signal, a second harmonic wave component, a quadruple harmonic wave component, and an orthogonal component which is obtained in accordance with a phase shift of the quadruple harmonic wave component by one quarter period. In the first phase adjustment, a phase relation of the fundamental wave component, the second harmonic wave component, and the orthogonal component is maintained in a predetermined phase relation, while a relation between the phase of the components and a phase of the phase modulation signal is adjusted. At this time, a level of the orthogonal component is controlled to be zero. In the second phase adjustment, the phase of the phase modulation signal is adjusted to make a level of the second harmonic wave component zero. Subsequently, the phase of the phase modulation signal is shifted in a positive output direction by one-eighth wavelength of the second modulation signal. Then, the phase of the phase modulation signal is adjusted to make the level of the quadruple harmonic wave component zero, and the phase of the phase modulation signal is shifted in the positive output direction by the one-eighth wavelength.

Patent CA-2146288-A1 (CA)
Title: Double detection system
Inventor: LORENZO JOHN L
IPC: G06K13/067
Filed: 1995-04-04
Abstract: The present invention relates to an electro-optical system for double document detection wherein an improved calibration is employed. To calibrate the system, a microcontroller generates a series of increasingly wider pulses, which are transformed into a series of respective increasingly higher ramp pulses to drive a light emitter (LED, a laser diode or fiber optic coupled laser) at gradually increased power until the predetermined value of an output signal of the light detector (photo-transistor) is achieved. Then the pulse width corresponding to the predetermined value of the output signal is fixed. This width becomes the drive for the light emitter until another calibration changes it. The microcontroller (with the software in it) monitors the output signal to determine a double-feed document condition if the output signal exceeds a predetermined value.      The system is capable of "hands-off" calibration. To detect a "true" double-feed document condition, a software timer counts a prolongation of the alteration of the output signal. Also, in order not to miss a "true" double-feed document condition when the area of overlapping is small, the distance between a front edge of the first overlapped document and a rear edge of the last overlapped document is measured. The system also declares a double-feed document condition if a space between two fed documents is no greater than a predetermining value. The system is also capable of self compensating for component variations, component deterioration and voltage variation over time, slight misalignment, and accumulated paper dust, if any. The system also provides a safety circuit to protect the light emitter from excessive power dissipation. If the situation of power down in the system occurs, the recalibration is not needed, since the system is provided with the non-volatile memory to store the fixed width. Each stage of the system is indicated by LEDs.
