Title: In-situ tuned microwave oil extraction process
Inventor: KIAMANESH ANOOSH
IPC: C10G1/04
Filed: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE      A method of creating a protocol for oil extraction or for  enhancing  oil  extraction  from  oil  reservoirs.   A process of devising and applying a customized electromag-netic  irradiation  protocol  to  individual  reservoirs. Reservoir samples are tested to datermine their content, molecular resonance frequencies and the effects of electro-magnetic field on their compounds.  Electromagnetic field frequencies, intensities, wave forms and durations necess-ary to heat and/or crack individual molecules and produce plasma torches is determined.  Equipment are selected and installed according to the results of the laboratory tests and the geophysics of the mine.  Dielectric constant of the formation is reduced by draining the water and drying it with electromagnetic energy.  A combination of the effects of microwave flooding, plasma torch activation, molecular cracking and selective heating are used to heat the oil within the reservoir, by controlling frequency, intensity, duration, direction and wave form of the electromagnetic field.    Conditions of  the  reservoir  are  continuously monitored during production to act as feedback for modifi-cation of the irradiation protocol.

Abstract: A speech coding method which can code a speech signal at a bit rate of 8 kb/s or less by a comparatively small amount of calculation to obtain a good sound quality.  An autocorrelation of a synthesis signal synthesized from a codevector of an excitation codebook and a linear predictive parameter of an input speech signal is corrected using an autocorrelation of a synthesis signal synthesized from a codevector of an adaptive codebook and the linear predictive parameter and a cross-correlation between the synthesis signal of the codevector of the adaptive codebook and the synthesis signal of the codevector of the excitation codebook.  A gain codebook is searched using the corrected autocorrelation and a cross-correlation between a signal obtained by subtraction of the synthesis signal of the codevector of the adaptive codebook from the input speech signal and the synthesis signal of the codevector of the excitation codebook.

Abstract: The present invention provides a pager in which a user can record a set phrase which the user wants to record and thereby can improve the usability of the pager.         A decoder decides whether a received address code belongs to the pager or not.  When it is decided that the selective address code is belongs to the pager, microprocessor 17 stores a message signal which follows this selective address code in a message memory area of RAM 7.          When a set phrase is stored, the microprocessor 17 records into set phrase recording area 6a of EEPROM 6 a portion of the message designated by function switch 8 as a set phrase through a microprocessor 17.

Title: Air conditioning diffuser apparatus
Inventor: SCOTT MICHAEL B
IPC: F24F13/06
Filed: 1992-04-10
Abstract: AIR CONDITIONING DIFFUSER APPARATUS          ABSTRACT OF THE DISCLOSURE            A flow control apparatus is for controlling flow of hot air through  a  ceiling  mounted  air  conditioning  discharge diffuser  receiving  supply  air  from  a  central  air conditioning unit.  The apparatus comprises a vertical duct connected to structure associated with a discharge diffuser cone,  and a butterfly valve or damper assembly mounted within the duct to control flow through the duct.   The damper assembly has a damper blade mounted on a spindle which is rotatable with respect to the duct.  A temperature responsive  coil rotates  the  spindle  in  response  to temperature  changes  in  the  supply  air  so  as  to vary position of the blade within the duct to control flow therethrough.  Threaded studs connect the spindle to the damper blade and permit easy angular adjustment of the damper blade with respect to the spindle to permit easy fine adjustment of opening and closing of the duct.  For heating, the duct is opened, and some hot air is directed downwardly into the room,  reducing stratification that would otherwise occur, while the balance of air is directed by the diffuser cones.  For cooling, the duct is closed and all the cooler air is controlled by the diffuser cones to flow outwardly across the ceiling.

Abstract: The synchronization process of the present invention fil-ters the received signal with an adaptive band-pass filter (101) while buffering the received signal in memory (108). The en-ergies of the input signal and the filtered signal are estimated (103 and 104) and the gain of the filter is adapted (105) based on the difference between the energies. The pole of the filter is adapted (102) to center the frequency of the input signal in the filter's pass-band. If a tone is detected (106), the length of the tone is determined (107) to ascertain if it is a frequency correc-tion burst (FCB). If the tone detected is an FCB, the signal in the memory is also the FCB that is then filtered in the band-pass filter (101) and the difference between the frequency of this signal ant 67.5 kHz is determined (109). This difference represents the frequency offset between the base station car-rier frequency and that of the mobile radiotelephone, and can be fed into the local oscillating means to compensate for the frequency offset. The boundaries of the FCB establish the time slot alignment of the TDMA structure being received from the base station.

Patent CA-2088083-A1 (CA)
Inventor: PAROLA DARIO L
IPC: H04Q3/58
Filed: 1993-01-26
Abstract: A method for monitoring a network communications channel to detect specific DTMF triggers transmitted by a network user during either a pre-answer or a post-answer period of a call supported by the channel, and, in response to the detected DTMF triggers, controllably prohibiting the propagation of subsequent DTMF signals transmitted over the channel by the network user. Specifically, possible disruption of a communication between the network user and other parties caused by transmission of DTMF signals is eliminated by advantageously transmitting the DTMF triggers during the pre-answer period of a call. Furthermore, another deficiency of prior network-based arrangements for restricting the propagation of DTMF signals is overcome, as the invention may be practiced without the introduction of any significant propagation delay to a network.

Abstract: The invention is a rapid, continuous test for glycated hemoglobin using a non-equilibrium affinity binding method. Agarose beads derivatized with 3-aminophenylboronic acid specifically bind glycated hemoglobin. This solid phase is incorporated into a sample processor card, modified to mix and to separate the test solution from the solid phase prior to absorbance readings. Two absorbance readings are made on the test solution, one immediately after mixing the reagent/diluent with the specimen, and one after a significant amount of binding has occurred. A linear correlation between total glycated hemoglobin and hemoglobin A1c permits standardization and reporting of units equivalent to % hemoglobin A1c.  Stable glycated hemoglobin solutions for use as standards in the assay, and a method for preparing the standards are also disclosed.

Abstract: ABSTRACT     A simulated log 10 is for use in a gas fire.  The log 10 consists of a first body 12 and a second body 14, attached together.  The second body 14 is an insert in the first body 12.  The first body 12 is of a first type of ceramic material, such as slip cast material.  The second body 14 is of a second type of ceramic material, such as ceramic fibre.  When the log is positioned in the flame of a gas fire, the ceramic fibre insert will glow more strongly than the main body of the log by virtue of the differences in materials.  This gives an improved simulation of a real fire.
