Abstract: METHOD AND APPARATUS FOR IDENTIFYING AND RENDERING OPERATIVE PARTICULAR DESCRAMBLERS IN A TELEVISION SIGNAL SCRAMBLING SYSTEM ABSTRACT OF THE DISCLOSURE An in-band television signal scrambling method and apparatus are disclosed which employ a scrambler which receives and scrambles a television signal and one or more descramblers for restoring the scrambled television signal to an unscrambled con-dition. A tier level encoding scheme is used to identify and render operative predetermined descramblers. The scrambler en-codes tier level coding information in the form of whiter-than-white pulses on a scrambled television signal, these pulses being detected by the descramblers, with only those descramblers ident-ifed by the tier level coding information being rendered operative to unscramble the scrambled television signal. The descramblers preferably employ a plug-in module into which the tier level coding information assigned to a particular scrambler can be pro-grammed. The scrambling operation may be accomplished by sup-pressing the amplitude of the horizontal synchronizing signals in a television signal, and generating timing pulses in the form of other whiter-than-white pulses in the scrambled television signal which cue the descramblers enabling them to reconstruct the sup-pressed amplitude horizontal synchronizing signals.

Abstract: IMPROVED ROCK BIT Abstract of the Invention A rotary cutting member of a rock bit is journaled on an axle portion of the bit body and provides a cavity between the axle portion and cutting member in which there are disposed a plurality of bearing elements for rotatably supporting the loads of the cutting member on the axle portion.  A pressurized fluid passageway extends through the bit body to the cavity for transmitting bearing conditioning fluid to the bearings.  At least one annular array of bearing elements is encased and supported in a ring of semi rigid porous, permeable plastic material having bearing lubricant in the pores and forming the bearing cage.  The cage and encased bearing elements fill the radial distance of the cavity to initially substantially block delivery of bearing conditioning fluid through the cavity.  Under bit operating conditions the plastic material is generally expelled from the cavity thereby opening the cavity to the pressurized bearing conditioning fluid from said fluid passageway,
