Abstract: INVENTION:  PRODUCTION OF ETHYLENE DICHLORIDE FROM ETHANE     INVENTORS:  BRUCE E. KURTZ, EDMUND W. SMALLEY, WALTER E. SONNERMAN and  JOHN R. VAN ATTA     ABSTRACT OF THE DISCLOSURE     A process is disclosed for the production of ethylene dichloride from ethane.  Ethane is introduced into an autather-mic (self-sustaining) cracking zone together with controlled poroportions of chlorine and oxygen.  The autothermic cracking zone is maintained at a temperature above about 700°C. but below 1000°C. for a sufficient time to convert from about 20 to 95 percent of the ethane having about 96 to 74 percent ethylene yield, respectively, based on the converted ethane.          The reaction mixture, containing predominant y ethylene and hydrogen chloride, is quenched with a volatile liquid.  The quenched mixture is passed, together with oxygen, into a catalytically activated oxyhydrochlorination zone to convert the ethylene, hydrogen chloride and oxygen to ethylene di chloride,  If vinyl chloride is desired as a product, part or all of the produced ethylene dichloride is passed to a second cracking zone for conversion to vinyl chloride pro-duct and hydrogen chloride.  The hydrogen chloride produced is recycled to the oxyhydrochlorination zone.  Ethylene di-chloride, vinyl chloride or mixtures of ethylene dichloride and vinyl chloride can be recovered as product, with sub stantially complete utilization of the hydrogen chloride produced.

Abstract: CIRCUIT FOR CONTROLLING A SEATBELT RETRACTOR     ABSTRACT OF THE DISCLOSURE          A circuit for controlling a seatbelt retractor of a motor vehicle.  The retractor is of the type which permits initial withdrawal of the seatbelt from the retractor and which locks to prevent further seatbelt withdrawal upon decrease of the withdrawal force or upon slight retraction of the seatbelt.  The control circuit prevents the locking of the seatbelt retractor if the vehicle is in a predetermined condition, such as its transmission lever being in a neutral or park position, and if the vehicle seating position for which the seatbelt retractor is provided is occupied.  Prevention of retractor locking simplifies and eliminates annoyance to a vehicle occupant fastening the seatbelt about him.

Abstract: Abstract of the Disclosure An apparatus for the safe storage of a plurality of fissionable masses including an array of discrete neutron absorbing shields which utilizes the principle of the neutron trap to reduce the multiplication factor of the storage array to a subcritical value when immersed in a neutron moderating medium. Each discrete neutron absorbing shield is designed to perimetrically encircle each of the stored fissionable masses.  Each shield is spaced such that the encircled fissionable mass is spaced from the next adjacent neutron absorbing shield by a distance determined by the enrichment of the fissionable masses and attenuation of the moderating medium.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus is provided for inserting terminals into a workpiece. The apparatus includes feeding means for sequentially advancing a supply strip of integrally connected preformed terminals toward a first station of the apparatus.  Grasping means are provided for grasping the leading one of the terminals at the first station and for maintaining a grasp on that one of such terminals until such terminal is inserted in the workpiece.  The grasp-ing means include first and second grasping plates normally biased apart to define a reception space for the leading one of said terminals, shearing means for severing the leading one of the terminals from the remainder of the supply strip, and actuating means for urging the grasping plates toward one another to grasp the leading one of the terminals therebetween for a pre-selected period of time.  The shearing means include a shearing edge passed by one of the grasping plates as they are urged toward one another by the actuating means such that the leading one of the terminals is sheared from the supply strip as that one of such grasping plates passes the shearing edge.  Finally driving means are provided which are operable to drive the grasping means toward the workpiece for insertion of the terminal therein. This provides a reliable automated technique which can simply, easily and rapidly establish terminals on substrates in an economic fashion.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to an improved method of producing a polymer of 2-pyrrolidone suitable for melt spinning into a white fiber employing an alkaline catalyst and sulfur dioxide as the co-catalyst.  The method embodies the use of SO2 within the preferred range of from 0.01 to 0.03 moles of SO2 per moles of 2-pyrrolidone coupled with a polymer color removal treat-ment, after washing the polymer cake to remove unchanged monomer and alkali.  This color removal consists of an oxidizing rinse, employing a liquid oxidant such as H2O2 and followed after a water wash, by a reducing bath consisting for example of a solution of sodium metabisulfite and followed again by a water wash.  The polymer resulting from this method is a white thermally stable resin capable of being melt spun into white fiber.

Abstract: ABSTRACT    Method of detecting flaws in the rims of lap seamed substantially cylindrical ferrous objects.  A magnetic sensor scans the object rim and generates a wave form signal containing portions which respectively represent magnetic field disturbances caused by rim flaws ant the rim lap area, the flaw wave form portion having a smaller amplitude and higher frequency than the lap area wave form portion.  The wave form signal is processed to obtain a relatively greater voltage amplitude for the flaw wave form portion.  Its total peak-to-peak voltage is obtained and compared to the maximum acceptable voltage value for flaws.  When the former exceeds the latter, a signal is generated which indicates unacceptability of the flaw.  Wave form signal processing preferably is through an A.C. coupled amplifier and through first and second high pass frequency filter stages.  The lap area wave form portion preferably can be removed from the wave form signal to obtain a non-lap area wave form signal whose total peak-to-peak voltage is similarly obtained and compared to a maximum acceptable voltage value for non-lap area flaws to obtain a signal which indicates unacceptability of the flaw. The entire rim of the object can be fully scanned within 390° of rotation of the object.

Abstract: PROCESS AND APPARATUS FOR MANUFACTURING REINFORCED ELASTOMERIC HOSES         ABSTRACT OF THE DISCLOSURE           A process is provided for vulcanizing an elastomeric reinforced hose or a hose having its core tube reinforced with fibrous material.  In accordance with the process a hose having an elastomeric sheath over its reinforcing material is preferably continuously passed through a tubular preheater which softens the surface of the sheath and the hose is then passed through a heated sizing die where only the surface is initially softened and then vulcanized before leaving the die.          The die sizes the diameter of the hose and at the same time smooths out the surface of the sheath.  The sized hose is passed immediately into a vulcanizer where it is heated to vulcanize completely.  The vulcanized hose is then cooled.         The apparatus provided for practicing the process has, a heated die, a vulcanizing unit and a unit for cooling the vulcanized hose all connected in series.  The apparatus may also have a tubular preheater.  The preheater is steam jacketed and may be provided with a means for lubricating the surface of the hose.  The sizing die may be steam jacketed and the vulcanizer may be one which heats the hose with live steam.  The vulcanizing unit is provided with a means for separating condensate from the hose and for flowing the con-densate out of the vulcanizer.  The entrance end of the pre-heater is sealed by means of an elastomeric sealing ring and an elastomeric sealing member is provided at the exit end of the apparatus.  The hose is cooled with cooling water fed into the bore of the cooling member.
