Abstract: INTEGRATED CLOSED LOOP ENGINE CONTROL            Abstract:     An integrated closed loop engine control is dis-closed in which the fuel delivery and timing functions of the engine are closed about a measurement of the engine's instantaneous rotational velocity.  Signals indicative of the profile of each torque impulse imparted to rotary out-put member of the engine from the burning of an air/fuel mix in the engine's combustion chambers are generated and electrically analyzed to detect perturbation caused by deviations of at least two different engine operational parameters from desired values.  Feedback correction sig-nals indicative of the magnitude of the detected perturba-tions  are  generated  to correct  the  fuel delivery and timing functions of an engine control to minimize the dif-ference between the actual operating parameters and the desired values. In an ultimate embodiment, the correction signals are applied to the engine control through a state variable matrix integrating the control of at least one engine parameter as a function of at least two different correction signals.

Abstract: ELECTROMAGNETIC CLUTCH WITH TWO STAGE TORQUE BUILDUP                Abstract of the Disclosure An electromagnetic clutch or brake of the type having a clutch inner body with inner and outer pole faces drawn into engagement with an armature in order to establish driving engagement of the clutch.  A two stage buildup of the torque is produced by an offsetting bias of the inner body pole faces by a nonmagnetic resilient ring separating the pole faces, and a shunt washer of a ferromagnetic material which serves to successively draw the pole faces into engagement with the armature by varying the reluc-tance through the inner and outer poles as the inner body is drawn into engagement.  The resulting two stage torque buildup slows the engagement time of the clutch to thereby enable the use of rapid action torque booster clutch designs in applications requiring slower clutch action.

Abstract: TIRE RETREADING SYSTEM Abstract of the Disclosure Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure.  Subsequently a pressure relief system permits the tires to exhaust faster than the vessel.  Each tire is prepared for retreading by applying a bonding medium between the tire periphery and the retread strip and wrapping the resulting assembly with a fluid impervious flexible cover. Tread stabilization rings, wick material and non-stick polymer film may be inserted between the tread strip and the cover. The improvement according to the invention also comprises interposing between the tread strip and the cover, a thin, flexible perforated film of synthetic polymeric material which causes the flexible cover to slide against the surface of the tread strip and to thereby penetrate into the tread grooves so as to conform with the tread profile.  A further improvement comprises interposing between the tread strip and the cover, at a location of the connection between the exhaust conduit and the cover, a pad of porous fabric which is stretchable in two directions to thereby aid in releasing air from the space.

Abstract: RCA 73,299 Abstract of the Disclosure A video signal processing system is disclosed including a sample and hold comparator arranged in a closed control loop with a video channel including a video amplifier for the purpose of providing automatic brightness control, and an automatic kinescope beam current limiter. The beam current limiter is coupled to a first point in the amplifier for controlling the amplifier signal gain to limit excessive beam current demand in a first control mode.  In a second control mode, the beam current limiter cooperates with the automatic brightness control network to control the D.C. output level of the video amplifier in the presence of excessive beam current demand.  The comparator response time is slow relative to transient variations of the D.C. level at the amplifier output induced by beam limiter action in the first control mode, but is otherwise sufficient to permit compensation of relatively long term variations in the output D.C. level.  Compensation of the transient D.C. variations is provided by coupling transient beam limiter control voltages developed in the first control mode to a second point in the amplifier, for opposing transient D.C. level variations which would otherwise appear at the amplifier output in response to beam limiter action.

Abstract: REPLACEABLE PROTECTIVE MEANS FOR        SHREDDER COMPONENTS                 Abstract of the Disclosure Replaceable protective means for protecting a component of a shredder from excessive wear includes a protective cap of hardened, wear resistant metal, and at least two pins and washers of readily weldable metal.  The protective cap has a U-shaped channel for receiving a por-tion of the periphery of the component.  The opposed walls of the U-shaped channel each have at least one pair of pin-receiving openings and the openings in each wall are aligned with those in the opposed wall.  When the cap is positioned in place on the component with the pin receiving openings in the opposed walls of the cap aligned with open-ings which extend through the end disc, the pins which have enlarged heads at one end which are larger than the openings in the disc can be inserted into the aligned openings and secured in place by welding a washer which also is larger in diameter than the openings in the disc to the other end of each of the pins.  The protective cap is thus retained in place on the component by the welded pin and washer combina-tions which are not directly attached to either the cap or the component.

Abstract: ABSTRACT OF THE DISCLOSURE           Poly(ethylene terephthalate) filaments of enhanced dyeability, low boil-off shrinkage (even in as-spun condition), good thermal stability over a large temperature range, and useful as texturing feed yarns and/or as hard yarns requiring no further drawing are prepared by spinning at a withdrawal speed (V in yards/minute) of at least about 5500 yards/minute and with a polymer temperature (Tp) measured (in °C) in the filter pack at a point 50-100 mils above the center of the spinneret plate of wherein (L) and (D) are the length and diameter (in mils) of the spinneret capillary and (w) is the throughput (in pounds/ hour) per capillary.  The filaments are characterized by a long period spacing above 300 A in their as-spun condition, and, whether in as-spun condition or after heat-treatment, by a low skin-core value as measured by a differential birefrin-gence in relation to their stress measured at 20% extension (which correlates approximately with the spinning speed), a large crystal size, and low amorphous orientation.  The continuous filament yarns may be draw-textured to provide textured yarns which also show enhanced dyeability.  The staple fiber yarns also have very useful properties as compared with conventional staple yarns.  A preferred process of spinning at these extremely high speeds is characterized by the use of a spinneret with capillary-dimensions that produce high shear as the polyester is extruded and is applicable also to copoly-esters, whose filaments show a similar low skin-core in relation to their stress at 20% extension, the precise values for copoly-mers being different from the relationship for poly(ethylene terephthalate).
