Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed herein is an engine system which comprises an internal combustion engine, an air admission system to admit scavenging air, under pressure, into engine cylinder through an additional intake valve and an EGR system.  The air admission system includes an air pump and an EGR conduit of the EGR system having an inlet end connected to the engine exhaust conduit and an outlet end connected to the air admission system upstream of the air pump to effect admission of re-circulated exhaust gas through additional intake valve together with scavenging air.  With this EGR system and the replacement of residual gas with scavenging air, the rate of exhaust gas in engine cylinder upon ignition is kept substantially constant over varying partial loads.

Abstract: ABSTRACT OF THE DISCLOSURE              Satisfactory nuclear fuels made of natural uranium powders originating with a solid and liquid reaction process involving ammonium are prepared by a particle modification step wherein the relative active surface area of the fuel particles is reduced by wet attrition milling while in the green state.  The grain size of the ceramic resulting therefrom is more uniform than for the unmodified powder, and undue grain growth of isolated particles is substantially eliminated, thus precluding or largely avoid-ing undue internal stresses and consequent pellet cracking under operating conditions.

Abstract: ADJUSTABLE INTERLOCK HAND LEVER     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 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 year 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 a 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.

A stationary center shaft is mounted on the side of a stationary cylinder while a rotary sleeve which is fitted over said stationary center shaft for rotation about the axis thereof is disposed on the side of a rotary cylinder.  A lubricating oil is injected between the rotary sleeve and the stationary center shaft so that a space between the cylinders may be utilized so as to provide a hydraulic bearing portion.          Thus, the rotary head assembly may be made compact in size and to a higher degree of accuracy.  In addition, the thrust load carrying point of the hydraulic bearing portion is located on the side of the rotary cylinder, and the portion adjacent to the thrust load carrying point has a sealing arrangement or construction as as to prevent the leakage of lubricating oil and to stabilize the rotation of the rotary cylinder.

Abstract: MICROWAVE METHOD AND APPARATUS FOR HEATING PAVEMENTS     Abstract of the Disclosure Pavement (12) is rapidly heated in depth by irradiation with microwave energy accompanied by supplemental surface heating which counteracts an inverted temperature gradient otherwise produced by microwave heating.  Energy efficiency is increased by performing the surface heating with thermal energy derived from the exhaust gases of a motor (19) which drives a generator (18) to energize the microwave source (63).  An energy applicator (36) simultaneously applies both the microwave energy and hot gas to a selected area of pavement while blocking release of microwave energy in upward and outward directions and is preferably attached to a mobile support (37) through support and positioning linkage (38) which enables shifting of the applicator between localized areas of pavement to be heated: A variety of paving operations and pavement repair operations are facilitated by enabling an efficient deep rapid heating of deteriorated pavement or surfaces to be paved or repaved or to which an additional layer of pavement is to be applied.
