Abstract: DATA RECOVERY METHOD AND APPARATUS USING  VARIABLE WINDOWS         Abstract In a data recovery system, encoded variable spaced digital data is recovered by provision of variable width windows which are expanded or narrowed so as to tend to center on the expected occurrence of valid data based upon knowledge of the contents of the current or the immediately preceding timing units and of characteristics of the encoding scheme.  The system employs pulse-to-pulse syn-chronization without modifying the underlying synchron-ization of the system such that the first pulse of a two-pulse series serves as a window size reference for an immediately subsequent pulse.  The window for a reference pulse is expanded at its trailing edge if, for example, the reference pulse is delayed beyond the tolerance of the detection system.  The leading edge of a window for the subsequent pulse is expanded if no pulse occurs within a minimum period following the reference pulse.  The encoding technique is particularly applicable to data storage and retrieval systems employing Modified Frequency Modulation (MFM) coding as commonly used in disk drive systems communicating with an input and output controller of a computer.

Abstract: RCA 73,402 Abstract of the Disclosure An automatic kinescope beam current limiter for a television receiver comprises a source of signal repre-sentative of kinescope beam current conduction, a first transistor responsive to the representative signal over first, second and third ranges of excessive beam currents above a threshold level, and a second transistor.  A first control signal derived from the first transistor modifies the video signal peak-to-peak amplitude (contrast level) when beam currents above the threshold level occur.  The output of the first transistor is selectively coupled to an input of the second transistor when beam currents beyond the first range occur.  A second control signal derived from the second transistor modifies the video signal D.C. component (brightness level) to limit beam currents beyond the first range, whereby both the peak amplitude and D.C. components are modified over the second range.  The first control signal is clamped to a fixed level in response to beam currents beyond the second range, whereby the video signal D.C. component is modified alone to limit beam currents over the third range.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of producing a synthetic foil flat-bottom bag capable of receiving liquid, fluid or pourable material and capable of standing up-right when filled, in which a bag closed at the bottom and open at the top is spread apart at opposite sides whereby at its bottom, a bottom surface with two outwardly pointed triangular tips is formed. The two tips are compressed flat with their two-coil walls and are folded downwardly by approximately 180° about a fold line laterally spaced from the bottom of the bag, while the tip ends are placed against the underside of the bottom wall.          Thereafter the two tip folds are crease-welded.  The thus produced bag has a supporting surface which is enlarged by the welded multi-layer folds and is stabilized, and tightly sealed by the crease welds in the area of the tip.  The fold-ing of the tip is preferably effected by means of a form plate which has two parallel form edges extending beyond the bottom surface of the bag.  Upon folding and prior to crease welding of the tips the form plate is removed.

Abstract: The production of improved photovoltaic solar cells and the like comprising both p and n type deposited silicon film regions is made possible by a process which provides more efficient p-doped silicon films with higher acceptor concentrations. The process utilizes previously known p-dopant metal or boron gaseous materials in unique forms and conditions in a glow discharge silicon preferably hydrogen and fluorine compensated deposition process. Thus, p-dopant metals like aluminum may be used in an elemental evaporated form, rather than in a gaseous compound form heretofore ineffectively used and deposited with the glow discharge deposited silicon on substrates kept at lower temperatures where fluorine and hydrogen compensation is most effective. Preferably boron in a gaseous compound form like diborane and other p-dopant metals in a gaseous form are used uniquely during the glow discharge deposition of silicon by heating the substrate to heretofore believed undesirably higher temperatures, like at least about 450.degree.C to 800.degree.C where at least fluorine compensation, if desired, is still effective. The improved devices, such as solar cells, can be manufactured in a continuous process on a web type substrate moved through a plurality of film deposition chambers. Each of the chambers is dedicated to depositing a particular type of film layer (p, i or n) and is isolated from the other chambers.
