Abstract: BOOTSTRAP DRIVER CIRCUITS FOR AN MOS MEMORY         ABSTRACT OF THE DISCLOSURE:          A high speed, low power bootstrap driver is disclosed for use in an MOS memory.  The basic driver includes first and second enhancement mode transistors for receiving a digital input.  The drain of the first transistor is coupled to a high impedance depletion mode transistor, and the drain of the latter transistor is coupled to the source of a low impedance transistor. Another enhancement mode transistor is coupled via its sources to the drain of the second enhancement mode tran-sistor and is coupled via its gate to the drain of the first enhancement mode transistor.  A capacitor is con-nected between the drain of the high impedance transistor and the drain of the second enhancement mode transistor. When a low level input is received, the drain of the first enhancement mode transistors is rapidly boot-strapped to a high level voltage above the positive power supply for use as an output signal.  A key modi-fication to the driver described above adapts the driver for use in a fully asynchronous environment.  Further modifications to the basic driver are described for use of the driver in a decoder, a buffer, and a clock generator.

Abstract: ABSTRACT OF THE DISCLOSURE         A fillet for use in holding a transparent sheet of glass or plastic spaced from artwork mounted in a picture frame.  The fillet has a one-piece construction and is pro-vided with a recess and a spacer portion.  Preferably, the fillet has a generally S-shaped body defining two recesses of different widths with each recess being defined by an end wall and an intermediate wall, the intermediate wall being common to the two end walls.  Each end wall is angled rela-tive to the intermediate wall and the material of the fillet is resilient so that the end walls can yield away from the intermediate wall to accommodate glass or plastic sheets whose thicknesses are greater than the minimum widths of the recesses.  The S-shaped fillet is reversible so that, in one position, it can receive a glass or plastic sheet of a rela-tively small thickness in one of the recesses and, in the other position it can receive a glass or plastic sheet of relatively large thickness in the other recess.  In either case, the glass or plastic sheet is effectively spaced by the fillet from the artwork to prevent engagement of the sheet and the artwork.

Abstract: ABSTRACT OF THE DISCLOSURE                The present invention relates to a method for pressworking articles and an apparatus to effect the same.  Thus, there is provided a method for pressworking of articles, and more particularly by punching, extrusion, closed-die forging, briquetting, injection moulding or by other similar processes of articles, wherein the transmission of the amount of energy necessary for the pressworking is effected in several steps, each step comprising a high-power phase with release of previously accumulated potential energy in an elastically-deformable energy carrier and of a low-power phase of longer duration with release of energy from an auxiliary energy source of lower power, while the energies, the displacements of the tools and their velocities are conditioned by a previously programmed optimum law for the levels and their transitions between the different phases, at which law the production process runs according to the method with smoother transitions and is not disturbed because of the fact, that the rate of its run during the longer phase of lower power is regulated so that it is sufficient to avoid an abrupt increase of the coefficient of friction between the workpieces and the tools, while the velocities of the latter do not alter their sign till the completion of the working of the articles, and during the low-power phase of longer duration there takes place a recharging with potential energy of the elastically-deformable energy carriers, and then it is possible to effect the next-following step of pressworking on the same article.

Abstract: ABSTRACT    An ignition system of the contactless interrupt type for an internal combustion engine is disclosed with a control circuit including a pair of solid state semiconductor devices with one connected to the other in a controlling relation.  The ignition system has a high voltage transformer with a secondary winding coupled to a spark plug and a primary winding shunted by the controlled one of the pair of semiconductors. A current flow is induced in the primary winding and then interrupted near its maximum value by rendering both of the semiconductor devices nonconducting.  The controlling semiconductor may be a gate controlled switch or so-called gate turn-off device while the controlled semiconductor may be a power transistor. The primary winding current flow is induced by movement of a flywheel supported permanent magnet past the high voltage transformer while the current interrupt feature includes a control coil coupled to the controlling semiconductor and positioned close to the high voltage transformer to be influenced by the permanent magnet motion.

Abstract: DIGITAL SIGNAL PROCESSING METHOD AND APPARATUS        ABSTRACT OF THE DISCLOSURE           An identification signal is generated to identify a digital signal, such as a digital video signal reproduced by a digital video tape recorder (DVTR), as odd or even. Commencing periodically, such as at the onset of each field interval, identification signals occurring at inter-vals in the digital signal are sampled,  and an odd plu-rality (e.g., three) thereof determined to be error-free are stored.  A synthetic identification signal is generated whose value is determined by the majority of the stored identification signals.  The generated signal is then stored, for example, in a cascade of flip-flops, to provide a second synthetic identification signal from the onset of each field interval until the majority of the sampled identification signals is determined.  In a circuit for processing a digital video signal, an identification signal for identifying line intervals as even or odd is derived by taking the modulo-two sum of field and frame identifi-cation signals to determine the state of the line identifi-cation signal at the beginning of each field, and thereafter inverting the identification signal at each line interval.

Abstract: Abstract A process for applying a patterned coating to a circuit board without the use of a patterning mask.  A surface of the circuit board is coated with uncured material having a cure reaction which is inhibited by the presence of oxygen.  The thickness of the material on land areas surrounding holes through the circuit board is reduced by causing a portion of the material to flow into the holes.  The material is then exposed, in the presence of oxygen, to an energy source which advances the cure reaction only of sublayers of the material which are isolated from the oxygen by overlayers of the material.          Surface layers of the material, including substantially the entire thickness of the reduced thickness portions of the layer, remain uncured, allowing subsequent selective removal of the uncured portions of the material.
