Abstract: A disk-shaped recording medium has a control record region in each recording region of successive recording tracks and which is divided into a first preformat region, a second preformat region and a focusing servo region arranged in succession in the direction along the respective track and respectively providing traverse data, tracking and clock data, and focusing servo data. An apparatus for reproducing data recorded in the tracks of such disk-shaped recording medium samples a playback output from an optical head scanning a track to detect focusing data from the focusing servo region and tracking data from the second preformat region and, in response thereto, applies focusing servo or tracking servo to the optical head. Further, traverse data is detected in the first preformat region to effect traverse counting of the recording tracks.

Abstract: (1) ABSTRACT OF THE DISCLOSURE    A speech coding and decoding apparatus used for linear predictive coding of a speech signal and for transmitting it in a digital signal.  In coding operation, a linear predic-tive residual signal is extracted from an input speech signal subjected to linear predictive analysis.  The strength of the correlativity between the pitch periods of the waveform of the extracted linear predictive residual signal is obtained for every plural blocks.  The time axis of the linear predictive residual signal for every two adjacent pitch period sections for the block in which the strength of correlativity of the waveform is not less than a predetermined threshold value and is larger than that of another block is compressed into a residual signal for one pitch period section repeatedly.  Quantization allotting bits are preferentially allotted to the portion of the linear predictive residual signal subjected to time-axis compression, and the quantized signal is transmitted.  In decoding operation, the partially compressed and quantized linear predictive residual signal is separated from the transmitted signal, and the separated linear predictive residual signal is inversely quantized.  The partially compressed portion of the inversely quantized linear predictive residual signal for every one pitch period section is partially expanded to the residual signal for two pitch period sections repeatedly so as to restore the (2) reproduced residual signal which has the same length of original residual signal.  The time axis of the linear predictive residual signal is compressed and expanded only at the portion which has a large waveform correlative strength, thereby ensuring good synthesized speech quality.          And time-axis of linear predictive residual signal is compressed and expanded within analysis frame,thereby enhancing the proof to transmission error.

Title: High purity polyether polyols
Inventor: MURPHY FRANK H
IPC: A23L33/20
Filed: 1990-05-29
Abstract: ABSTRACT     The present invention concerns high purity polyether polyol compositions and, preferably, polyethylene glycol (PEG) compositions which are useful to provide low calorie food for those who wish to control their tendency to be overweight.  A process for the purification of polyethylene glycol through cation and anion ion exchange resins is known.  However, this process does not remove the PEG oligomers.  The present process comprises subjecting the polyether polyol compositions to membrane filtration to remove substantially all of the impurities, leaving only less than about 10 parts per million of the low molecular weight oligomers in the polyether polyol composition.     37,537-F

Abstract: ABSTRACT OF THE DISCLOSURE A dual-purpose lottery play ticket and boarding pass issued by a commercial passenger carrier to each passenger boarding an aircraft for commercial flight.  The invention comprises two parts, the first part of which is to be retained by the air carrier upon boarding, while the second part of which is to be retained by each passenger.  Both first and second parts include data printed thereon describing each passenger by name and/or frequent flyer number, and information to finding a particular  schedule  flight designation.   Both  parts  also include identical lottery play indicia printed thereon so that each  passenger  has  the  opportunity  to  enter  a  lottery sponsored by the air carrier.   By each party retaining a properly validated part of the invention, proof of entry and selection are secured.  The preferred form of the invention envisions each passenger making a lottery number selection in conjunction with boarding the aircraft;  however, a random lottery number selection may also be preprinted on each part, random number selection thereafter by the air carrier still determining winners in either event.

Title: System and method for monitoring drill bit depth
IPC: E21B47/04
Filed: 1990-10-03
Abstract: ABSTRACT OF THE DISCLOSURE       Methods and apparatus for accurately determining drill bit depth are provided.  A hook load is sampled at a rate of at least 4 Hz and is compared to a low threshold to establish a slips-in condition.  A determination is made retroactively that the drill string stopped moving when the hook load passed through a high dynamic threshold.  On the slips-out procedure, the identical high threshold is used, with movement established when the hook load exceeds the high threshold.  The high dynamic threshold corresponds to the points at which the drill string actually stops and starts moving in the slips-in and slips-out procedures.          The apparatus provided is a drawworks encoder mounting assembly which retrofits an auxiliary brake section of the drawworks or the rotary seal air coupler of a drawworks clutch.  A split ring gear fits around and is secured to the rotating cylinder of the rotory seal air coupler.  The split ring gear is part of a pulley having another gear and a drive belt, such that rotation of the drum and rotorseal air coupler cylinder is translated to a shaft of an encoder coupled to the second gear.  The encoder thereby tracks the rotational movement of the drawworks drum.  At desired times, also provided is a second encoder which is part of a calibrator which, via a calibrator wire, precisely measures the location of the travelling block relative to a known vertical location.  The first and second encoder readings are compared continuously and are used to provide excellent calibrations between the drum rotation and the travelling block movement.

Title: Frying-fat composition
Inventor: VAN DER HEIJDEN ARNOLDUS
IPC: A23L33/20
Filed: 1990-12-21
Abstract: ABSTRACT The present invention is concerned with a fat composition suitable for frying, comprising at least 60 wt.% of fat, wherein the fat essentially consists of a mixture of one or more non-digestible polyol fatty acid polyesters and optionally triglyceride fat and the fat comprises from 0.1-50 ppm silicon oil and from 1 to 1000 ppm of an anti-oxidant selected from the group of tocopherols, tocopherol derivatives, tocopherol precursors and mixtures thereof.            We have found that off-flavour generation observed when a fat composition containing polyol fatty acid polyesters is used in frying, can very effectively be retarded by the inclusion of an effective amount of, in combination, silicon oil and an anti-oxidant selected from the group of tocopherols, tocopherol derivatives, tocopherol precursors and mixtures thereof.
