Abstract: In some embodiments, the present disclosure provides a composition comprising 1) about 97.5 wt % to about 99.9 wt % of a first polyethylene having a density of about 0.91 g/cm3 to about 0.94 g/cm3, and a melt strength of about 10 mN or greater; and 2) about 0.1 wt % to about 2.5 wt % of a second polyethylene having an Mw of about 500,000 g/mol or more. In some embodiments, the composition is a film. In some embodiments, the present disclosure provides a method of making a composition comprising blending a first polyethylene of any embodiment described herein and a second polyethylene of any embodiment described herein.

Abstract: A video signal dropout compensator stores information from at least one incoming television line which is represented by a plurality of samples of combined liminance and chrominance signal components. The samples occur at a rate equal to four times the chrominance subcarrier frequency. When a signal dropout is detected in one or more of the samples, a replacement sample is generated using samples from at least one adjacent television line. The value of the sample on the adjacent line at the horizontal location, corresponding to the dropout sample, is subtracted from the sum of the samples before and after this corresponding location sample. The resultant value gives a dropout replacement sample with proper chrominance phase having a close approximation of the correct luminance value.

Abstract: Apparatus for optically recording and reading information on a disc medium rotating surface. The information is recorded on concentric or spiral tracks continuously or in parts. The information, which can represent, for example, television video, x-ray, or digital data signals, are addressed by codes that identify the track on which the information is recored preceded by the address code. The recording mechanism can record a new track adjacent to the previous track if the disc has been moved between recordings. There are also means for compensating for eccentricity errors introduced by small changes in the radial dimensions of the disc. The spacing between tracks is typically 2.5 microns although the eccentricity errors may exceed the span of ten tracks. Typically, 4,000 tracks per cm can be recorded.
