Abstract: PNEUMATIC TIRE HAVING A RUN-FLAT INSERT STRUCTURE                     Abstract of the Disclosure A run-flat insert structure for a pneumatic tire is disclosed in which the insert structure comprises a homogeneous elastomeric material and is fully enclosed and pneumatically inflated. The insert structure is mounted within the cavity formed by the pneumatic tire and the wheel rim upon which the tire is mounted. The insert structure is shaped and spaced from the interior walls of the tire such that contact between the insert structure and the interior tire walls is minimized during rated load carrying and inflation conditions of the tire. The volume of the insert structure is less than 50% of the volume of the cavity formed by the tire and the wheel rim to thereby assist in avoiding undesirable contact between the insert structure and the tire. During the deflated condition of the tire, the insert structure supports the tire and its load at a deflection that prevents excessively rapid deterioration of the tire while running in the de-nated, run-flat condition.

Abstract: DUTY CYCLE TRANSLATOR WITH SOLENOID MODELING CIRCUIT FOR ADAPTIVE BRAKING SYSTEM                      ABSTRACT OF THE DISCLOSURE   An adaptive braking system for a vehicle having fluid pressure operated brakes includes a skid detecting circuit for generating a skid detecting signal when an incipient skidding condition is detected, a pressure command generator which is responsive to the skid detecting signal for generating a pressure command signal, and a duty cycle translator responsive to the pressure command signal to actuate the brake pressure modulator.  The duty cycle translator includes a circuit which generates a signal modeling the actual pressure level in the vehicle brake actuators.          Since the modulator is actuated by a solenoid which is powered by the vehicle electrical supply, the opening and closing times of the solenoid will vary as a function of the power output of the vehicle power supply, which can vary over a substantial range depending upon ambient temperature and upon the strength of the vehicle battery.  Accordingly, the duty cycle translator includes a circuit which models the opening and closing times of the solenoid actuators and the reaction time of the mechanical valve components to thereby more closely model the actual pressure level in the vehicle brake actuators.

Abstract: ABSTRACT OF THE DISCLOSURE         Properties of the surface of low melting substrate parts including low melting, high conductivity reactive metal parts, are modified by forming an alloy casing thereon having the metal of the substrate as a first (matrix) component thereof together with a higher melting material as the second (reinforc-ing) component.  The higher melting component is coated on the substrate, melted under laser heating, with gas shielding to avoid oxidation, and mixed with a melted portion of the substrate through convective circulation and the mixture is rapidly cooled to produce the alloy casing.  Then the casing may be rescanned with the laser beam to rapidly melt and resolidify the casing with refined grain structure.  Such grain refining may also be applied to uncoated substrates.

Abstract: ABSTRACT OF THE DISCLOSURE         In a stabilized fiber optical measuring device for measuring dynamic transients of physical magnitudes, a trandsucer acted upon by the physical magnitude to be measured receives light transmitted by an optical fiber from a light generator and transmits an optical signal to an optical detector.  The transducer modulates at least part of the optical input signal such that the optical output signal therefrom contains at least one measuring component representing the magnitude to be measured and at least one stabilization component.  The optical output signal is detected and the measuring component and the stabilization component are separated from one another and respective electrical signals generated such that the dependence of the measuring signal on instabilities in the measuring device can be compensated by a compensating signal.  The transducer also attenuates the optical input signal in dependence on the magnitude of the measuring component.

Abstract: Abstract of the Disclosure An oil cooled diesel engine piston is designed to restrict heat loss from the combustion chamber through provision of a combustion chamber insert defining a central non-oil-cooled chamber and a surrounding annular insulating air gap.  The air gap controls heat flow primarily between the combustion gas exposed wall of the insert and an adjacent coolant exposed wall of the main piston volume.          The insert is press fitted into a recess in the main piston body and is positively locked therein by a retaining ring.  A seal ring closes expansion clearance provided at the upper edge of the insert against signifi-cant gas flow into the insulating air gap.  Insulating efficiency of the air gap is maximized by forming the gap with a thickness throughout a major portion of its extent of between about .040 and .060 inches.          Numerous additional features are also disclosed.

Abstract: 23.                COEFFICIENT TAP LEAKAGE FOR            FRACTIONALLY-SPACED EQUALIZERS Abstract of the Disclosure A quadrature amplitude modulated (QAM) data signal transmitted at T symbols per second is sampled in a data receiver at a rate of 2/T samples per second and applied to a transversal-type equalizer structure having taps spaced at T/2 second intervals.  A demodulated equalized signal generated once every T seconds, is quantized to form a decision as to the value of the original modulating data symbol.  An error signal   is formed in response to the pre- and post-quantized values of the demodulated equalized signal.  Tap coefficients used in generating the equalized signals are updated in response to a) a correction term which is a function of the error signal and b) a predetermined tap leakage term which has a constant magnitude. The introduction of the tap leakage term maintains the coefficient values at minimum levels.
