Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides an improved method and apparatus for controlling the tension in a tensionally fragile web of material being pulled by a constant speed processing machine from either one of a pair of supply rolls.  A first festooning roller effects the control of the web tension during the normal operation of the machine.  During the splicing of the web from one supply roll to another, the tension in the web would tend to dramatically in-crease.  This tendency is offset by a second festooning roller engagable with the web and shiftable in a web tension decreasing direction only upon the occurrence of web tensions substantially in excess of the normal tension range.  Means are provided to restrict the rate of return movement of the second festooning rol-ler to that which falls within the control limits of the first festooning roller, thus eliminating any tendency to accelerate the new supply roll to a speed above the desired machine operating speed.

Abstract: Case 4215   DAS/smt   10/1/80 VINYL HALIDE-POLYOLEFIN POLYMER AND COPOLYMERS                 AND METHOD OF MAKING       ABSTRACT    The present invention relates to production of vinyl halide-polyolefin graft copolymers by a liquid phase bulk polymerization process wherein the process is carried out in the presence of a diluent.  Suitable diluents preferably have vaporization pressure characteristics, within 100 psi., and similar liquid state vis-cosity, as vinyl halide monomer.  The diluents are soluble in vinyl halide monomer under reaction conditions and are inert to the polymerization mass.  The diluents are straight or branched chain, or cyclic saturated hydrocarbons having from about 3 to about 15 carbon atoms and, more preferably, from about 4 to about carbon atoms.  Particularly useful diluents are n propane, n-butane, isobutane or mixtures thereof.  The diluents are utilized in amounts from about 0.2 to less than about 50.0 percent based upon the total weight of the reaction charge.

Abstract: LASER MEASURING SYSTEM AND METHOD FOR TURNING MACHINE            Abstract A laser measuring system is associated with a two axis turning machine (10),having  a tool turret (12), to permit the dimensions of a machined part to be ascertained without removal of the part or workpiece from the chuck (18) of the machine.  A gage head (36), which includes a retroflector (40), is mounted upon the turret which is indexible to a measuring station in which part measurements may be taken.  The turret is mounted upon an X-axis slide (32) movable perpendicular to the chuck axis which, in turn, is mounted upon a Z-axis slide (26) movable parallel to the chuck axis. An interferometer (48) is fixedly attached to the Z-axis slide so as to be in alignment with the retro-flector when the retroflector is in the measuring station.  A Laser beam source (52) and a beam receiver (54) are mounted on or adjacent the machine such that they are in proper alignment with the interferometer. A collar (20) on the chuck furnishes a reference surface which functions as a fixed gage calibration point.

Abstract: TITLE:  INFORMATION COMMUNICATING APPARATUS AND METHOD         ABSTRACT OF THE DISCLOSURE         Apparatus and method is provided for secured communication of information as in effecting financial transactions between two individuals. Apparatus is provided in the form of units personal to respective individuals and including display of information to be communicated, electronic circuit means providing automatic security of transmission between relatively remote units that are intended to be included in a specific transfer of information, electronic information storage means for recording of communicated information, and radiant energy signal transmitting devices for effecting coupling of any two selected apparatus units that are to participate in the information transfer. Time-base controlled signal encoding is utilized to effect generation of the communication to the two selected units.  In the method of this invention, each of two selected units are operated to generate the same information signal of an agreed information transfer and a security identification signal which is associated with the respective unit. Transfer of information is effected in sequence with each unit transmitting its information signal and security identification signal in encoded form to the other unit.  Each unit compares the received transmission with its information signal and, if it compares, continues its signals to the other unit.  Correct comparison in both units then effects termination of the information communication.

Abstract: RCA 76,823 INTEGRATED PROTECTION CIRCUIT            ABSTRACT OF THE DISCLOSURE Disclosed is a protection circuit which may be used, for example, in a television receiver to protect circuitry formed within an integrated circuit from damage due to excessively high voltage transients.  The protection circuit comprises a PNPN structure forming a silicon controlled rectifier (SCR) and metal-oxide-semiconductor (MOS) transistor integral to the SCR structure.  The SCR and the MOS transistors are arranged to form a two terminal protection circuit which is rendered conductive when the potential difference across the two terminals is greater than a predetermined threshold.  One terminal of the protection circuit is connected to an input or output signal terminal of the protected circuit, and the other terminal is connected to a reference terminal to which a reference potential such as ground potential is applied.  Transient voltages appearing at the integrated circuit terminal greater than the predetermined threshold voltage causes the protection circuit to conduct current, thereby dissipating the energy of the high voltage transient and protecting the integrated circuit from damage.  In one embodiment, the gate electrode of the MOS transistor is connected to the reference terminal, and in another to the signal terminal.  The latter connection provides a much larger predetermined threshold voltage than the former, and typically considerably in excess of the supply voltage.

Abstract: CONTROL UNIT BRAKING DEVICE     Abstract of the Disclosure A single lever control unit for sequentially operating a transmission and throttle and, selectively, for operating the throttle independently of the transmission.  A throttle shaft assembly disengages from a throttle gear by pulling out the shaft while in the neutral position.  A double key on the throttle shaft disengages from a keyway in the throttle gear and a spring-loaded pin engages a cavity in the throttle gear to lock both shift and throttle gears in the neutral position.  Throttle only may then be applied.  When the hand lever is returned to the neutral position, the throttle shaft automatically engages the throttle gear and the locking pin automatically disengages by means of spring loading.  The locking pin prevents pulling out the shaft in other than the neutral position.        A spring provides axial loading between the throttle arm connected to the shaft and a friction plate mounted on the shaft. This loading creates a frictional drag which prevents throttle creep. Additional throttle braking is achieved during throttling by means of an adjustable screw forcing a friction pad against a  specially profiled side of the throttle gear.       An adjustable flange accommodates a neutral interlock lever. The flange can be angularly oriented in any desired position.
