Abstract: C-2918                           D-2,217 WINDING PREVENTION BELT RETRACTOR FOR       PASSIVE SHOULDER BELT SYSTEM          Abstract of the Disclosure:          An inertia locking seat belt: retractor for winding a shoulder belt having one end mounted on the vehicle door to move the belt between stowed and restraining positions upon movement of the door.  The retractor has a winding prevention mechanism including a pawl and ratchet for selectively blocking belt winding rotation of the belt reel to hold the belt extended at a set length to establish a slackened comfort condition rela-tive the occupant.  A manually actuatable control means has a normal condition blocking control of the pawl by a control disc frictionally clutched to the reel and is manually actuatable to release the pawl for control by the disc. The control disc actuates the pawl to provide the set length, defines a range of unwinding wherein the pawl is temporarily deactuated to permit subsequent rewinding to return the belt to the set length, and disengages the pawl upon still further unwinding rotation so that the pawl is deactuated upon belt unwinding during opening of the door.  The manually actuatable control means may be operated to temporarily deactuate the pawl to allow belt unwinding.  The pawl blocks return of the manual control means to the normal pawl blocking condition until belt unwinding causes the control disc to deactuate the pawl.

Abstract: ABSTRACT The invention is a process for economically recovering carbon black, oil and duel gas from used tires.  Used tires are physically sliced and frag-mented.  The fragments are pyrolized in an oxygen-limited, hydrocarbon vapor at subatmospheric pressure in a reactor while being refluxed with process char, preferably.  An embodiment showing the reflux with process heavy oil is also shown, but this embodiment is not preferred and has deleterious effects on the pro-cess.  Entrained char is separated from the vapor phase products of the pyrolysis, and the vapor phase products of the pyrolysis are then fractionated into oil and fuel gas.  A preferred embodiment condenses reactor vapors in two stages at two temperature levels to produce a high temperature flash point heavy fuel oil and a light fuel oil essentially in the naptha boiling point range.  The fuel gas can be compressed and burnt to provide process heat.  The entrained char and some heavy oil is returned to the reactor.  Solid phase pyrolysis products are stripped of trash and milled to carbon black in an air swept roller mill.  Carbon black is mechanically separated from the effluent air stream of the roller mill and formed into pellets with added water and dried in a series  multi-stage fluid bed dryer.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides data processing duplication and internal error checking within an integrated circuit chip at intermediate points along the logic chain.  In one aspect of the invention. duplicate functional logic within the chip is utilized together with multiple fault detectors to provide error checking of the primary logic chain, mechanical inter-connection failures, and power and clock pulse checking.  The detectable failures are both transient and hard failures.  Other problems are in addition resolvable by utilization of duplicate complementary logic in place of duplicate functional logic, such other problems including chip contamination during manu-facture, mask problems and functional design problems.  The multiple fault detectors provide a multiplicity of error signals which are multiplexed within the chip to produce encoded output error signals each of which designates the fault which has been detected within the chip.  These encoded error signals are routed to a special error handling chip which receives encoded error signals from a large number of places, such as a group of chips or circuit cards, and by correlating the information contained in the encoded error signals is able to identify the source of the error as a particular VLSI chip, the interconn-ections between VLSI chips, a particular circuit card, a power supply line to a circuit card or a group of such cards. or other faults.

Abstract: ABSTRACT OF THE DISCLOSURE An interrupt handling apparatus for a data proces-sing system comprises a plurality of processing units and a working memory which the units may access through a common bus by means of multilevel interrupt or access requests.          Access requests are forwarded by each unit to a bus access controller preferably made part of the working memory through a single lead for each unit, irrespective of the access re-quest level, and if the priority level of an access request is high a high level access request signal is distributed by the high level interrupting unit to the other system units, which are responsive to such signal and mask any possible access request of a lower level.  The bus access controller grants access to one unit at a time on a priority basis determined by a priority network in the controller totally insensitive to any level difference of the access requests.
