Title: Fibrillated ptfe modified rubber
Inventor: BAUER RICHARD G
IPC: C08L9/00
Filed: 1992-03-13
Abstract: ABSTRACT OF THE DISCLOSURE Low strain modulus of a sulfur cured rubber is improved by incorporating a fibrillated polytetrafluoroethylene (PTFE) into uncured rubber. Other compounding ingredients may be conventional and in conventional amounts.  The amount of fibrillated PTFE is typically from about 0.5 to about 8 phr; the amount required will vary from grade to grade of PTFE. The resulting vulcanized rubber is particularly useful as a tire tread stock, the vulcanized rubber has a higher low strain modulus (e.g., modulus taken at either 50% or 100% elongation) than does otherwise similar rubber containing no PTFE.

Filed: 1990-11-21
Abstract: A disposable video cassette for rotatably mounting a pair of reels for a recording tape in juxtaposition to allow transfer of the tape from one reel to the other as they are rotated in unison when the cassette is operating in a video cassette recorder (VCR) has a housing formed from a position of a singly flat paperboard blank having plural cutouts and fold lines for mounting the reels and accommodating rotation therein, for loading the cassette directly into the VCR. A pair of the cutouts is spaced apart in one side of the housing to expose the respective rotational driving mechanisms of the pair of reels in the housing, for mating with the driving mechanism of the VCR when the cassette is loaded therein. Another position of the blank constitutes an appendage to the housing conforming to the shape of the housing when formed. The appendage has fold lines to enclose the housing therein, to provide an integral mailer for the cassette, and is attached to the housing along an easy-tear fold line to permit ready removal of the mailer when the cassette is to be used in a VCR. The mailer when detached becomes printed material, i.e. a coupon, educational material, pharmaceutical detail material, games, etc.
Patent CA-2071557-A1 (CA)
Title: Use of iteration to improve the correction of agc dependent channel-to-channel gain imbalance
Inventor: PRINGLE RICHARD C
IPC: G01S13/88
Filed: 1992-06-18
Abstract: A method and apparatus that uses iteration to achieve a better prediction of the values of the commands need to balance the gains of .SIGMA. + .DELTA. and .SIGMA. -.DELTA. channels of a radar guidance system, when an imbalance occurs due to a change caused by the AGC circuitry. An improved method of measuring channel-to-channel gain imbalance versus AGC measurements is provided, which produces modified input values that are used as commands that correct the mismatch during missile flight so that residual error is minimized and more accurate guidance is achieved. The present method is implemented by measuring the gain imbalance at predetermined AGC points during system calibration, and iterating these measurements to produce a relatively small channel-to-channel gain imbalance at the .DELTA.AGC amplifiers. The measured imbalance is then converted to .DELTA.AGC commands and applied to the .DELTA.AGC amplifiers. The resulting gain imbalance is measured and this value is added to the originally value. This iterated value is again converted to .DELTA.AGC commands and applied to the .DELTA.AGC  amplifiers, and again the imbalance is measured, and is added to the first measurement. This procedure is repeated until a satisfactory level of error is measured which produces the proper correction factor that balances the channel-to-channel gains for each value of AGC. These correction factors are stored in a lookup table and are subsequently applied to the missile during flight. The improved apparatus of the present invention comprises a .DELTA.AGC controller containing a lookup table that contains the correction factors determined using the above method and an amplifier control circuit that responds to the correction factors to apply modified gain factors to the .DELTA.AGC amplifiers. These correction factors are applied to the .DELTA.AGC amplifiers during operation of the guidance system to achieve more accurate missile guidance.
