Abstract: ABSTRACT OF THE DISCLOSURE    A valve permits articles disposed within a sterilizer container to be exposed to an entire sterilization cycle, yet seals the sterilizer container upon completion of the cycle.          The valve includes a housing which defines a passage through which fluid can flow between the interior and exterior of the sterilizer container.  A sealing member seals the passage after a predetermined number of high and low pressure stages of a sterilization cycle has been completed.  A cam member is recip-rocated as the high and low pressure stages of the steril-ization cycle are performed, each reciprocation causing the sealing member to move one step closer toward sealing the sterilizer container.  Apparatus is provided to permit the valve to be reset for further use of the container.

Abstract: ABSTRACT OF THE DISCLOSURE                     POLYACETYLENE PRODUCTION    This invention relates to a process for producing an oriented, crystalline poly(acetylene) (III) in film or fibrillar form by solvent casting a film from a solution of a polymer of the general formula (V) derived from a precursor monomer (IV), and transforming the pre-cast film of polymer (V) under tension or in a stress field into the poly(acetylene) (III),  The transformation is carried out at a temperature between 20 and 200°C under reduced pressure over a duration of between 1 and 100 hours in an atmosphere inert to the precursor polymer (V) film and to the poly(acetylene) (III). Poly(acetylenes) are conducting polymers and find use in solid state batteries, field effect transistors and the like.

Abstract: APPARATUS AND METHOD FOR MEASURING THE CONCENTRATION OF LARGE PARTICLES IN A GAS Abstract of the Disclosure The invention provides apparatus and method for measuring the concentration of large particles in a gas which may also contain small particles.  The apparatus comprises a triboelectric charging means which effects triboelectric charging of the large particles in the gas, and charge measuring means for measuring charges on the particles in the gas after it has passed the triboelectric charging means.  The triboelectric charging means can be a curved section of an air intake duct or the Compressor of a turbocharger. The apparatus enables the operation of an engine or other air consuming device to be interrupted when the concentration of large particles in the incoming air is sufficient to damage the engine, but avoids un-necessary shutdowns due to the presence of small parti-cles, e.g., smoke particles, which are too small to damage the engine or other device.

Abstract: IMPROVED PROCESS FOR THE STABILIZATION OF ACRYLIC FIBERS                    ABSTRACT OF THE DISCLOSURE         The present invention provides an improved process whereby the thermal stabilization of acrylic fibers is accelerate.  The process comprises providing a zone of electron radiation and continuously passing a continuous length of acrylic fibrous material through the zone so as to provide an energy absorption of from about 5 to about 30 megarads.  The residence time of the acrylic fibrous material in the zone of electron radiation is less than five seconds.  The continuous length of acrylic fibrous material is subsequently continuously passed through a thermal stabilization zone wherein the acrylic fibrous material is heated in an oxygen-containing atmosphere provided at a temperature in the range of about 220°C. to 310°C. for about 10 to 30 minutes.  The acrylic fibrous material formed thereby is thermally stabilized (i.e., black in appearance, retains its original fibrous configuration substantially intact, and is non-burning when subjected to an ordinary match flame).  The electron radiation treatment has surprisingly been found to accelerate the desired thermal stabilization when compared to prior art processes which do not include the treatment of acrylic fibrous material by electron radiation.

Abstract: INVENTOR:   WERNER HONEGGER          INVENTION:  METHOD AND APPARATUS FOR FORMING MULTI-LAYER COILS             FROM SUBSTANTIALLY FLAT, FLEXIBLE PRODUCTS, ESPECIALLY PRINTED PRODUCTS, ARRIVING IN IMBRICATED PRODUCT FORMATION                ABSTRACT OF THE DISCLOSURE     Before winding-up the printed products arriving in imbricated product formation, the thickness of the imbricated product  formation  travelling  toward  a winding mandrel, respectively  toward  a product  coil  or package  forming thereupon,  is regulated to a prescribed value.   This is effected by spreading or compacting the printed products within the imbricated product formation.  For this purpose a first conveyor device is driven at higher or lower speed than a second preceding conveyor device.   The imbricated product                \ formation of prescribed thickness is wound-up upon the winding mandrel together with a winding strap maintained under tension which always lies upon the outer side of the coil layer being formed.  By regulating the thickness of the imbricated product formation to be wound-up so as to have a prescribed value which remains  essentially  constant  throughout  the  winding-up procedure, it is possible to form product coils of essentially constant diameter with a prescribed constant length of winding strap independently of the thickness of the arriving printed products.

Abstract: A B S T R A C T     An apparatus for the flash vaporization and distillation of a liquid reaction-mixture of a high pressure, having a distillation column, a flash valve for flash vaporization of the liquid reaction-mixture of a high pressure, and members for directing unvaporized liquid drops remaining after the flash vaporization into the distillation column, characterized in that the flash valve has a socket and closer member movable to adjust a clearance between the socket and the closer member and thereby adjust the flow rate and extends inside the distillation column and that the members for directing the unvaporized liquid into the distillation column are walls fitted in front of the flash valve in the distillation column in order to separate drops of unvaporized liquid from the produced vapor and to direct them downwards.  This apparatus both allows utilization of the heat content for distillation, and also tends to minimize reverse reactions in the liquid which can occur as the result of the pressure decrease, as the delay between depressurization and distillation is minimized.

Abstract: MISCIBILE OIL FLOODING AT  CONTROLLED VELOCITIES    (D#78,120 -F) ABSTRACT         The disclosed invention is a method of conducting a miscible flood with a flooding medium predominantly composed of carbon dioxide or nitrogen in a shorter period of time with acceptable hydrocarbon recovery.  The invention is practiced by injecting a predominantly carbon dioxide or nitrogen medium into the underground hydrocarbon reservoir at such a rate as to produce a frontal advance velocity in the reservoir of about 2 to about 15 times the critical velocity of flow for that flooding medium through the instant reservoir.  This high flooding velocity, substantially above critical velocity, is maintained until the flooding front has traveled about 60% to about 90% of the distance from the injection to the production systems.  At this time, the frontal advance velocity is reduced to a value approximately equal to or less than the critical velocity for the remainder of the miscible flood.
