Abstract: ABSTRACT OF THE DISCLOSURE     GENERATION OF ENERGY      A method of generating energy which comprises utiliz-ing relatively lower temperature available heat to effect partial distillation of at least portion of a multicom-ponent working fluid stream at an intermediate pressure to generate working fluid fractions of differing compositions. The fractions are used to produce at least one main rich solution which is relatively enriched with respect to the lower boiling component, and to produce at least one lean solution which is relatively impoverished with respect to the lower boiling component.  The pressure of the main rich solution is increased whereafter it is evaporated using relatively higher temperature heat 40.1 to produce a charged gaseous main working fluid.  The main working fluid is expanded to a low pressure level to release energy.  The spent low pressure level working fluid is condensed in a main absorption stage by dissolving with cooling in the lean solution to regenerate an initial working fluid for reuse.

Abstract: ABSTRACT            A DEVICE FOR REPORTING ERROR CONDITIONS OCCURRING   IN ADAPTERS  TO THE DATA PROCESSING EQUIPMENT              CENTRAL CONTROL UNIT            In data processing equipment handling communication lines connected to a central control unit (CCU) through adapters and a CCU input/output bus, an error reporting device is provided in each adapter for reporting error conditions  occuring  in  the  adapter  to  the  central control unit. The adapters are of the type including a microcode controlled microprocessor provided with input and output buses connected to the CCU input/output bus through  an interface.  The error reporting device in association with dedicated circuits in the interface insures the transmission of the error conditions occur-ing in the adapter to the central control unit,  even when such error conditions affect the integrity of the microcode. When the error reporting device detects an error affecting the microcode integrity, it generates a hard stop  signal which causes  the  operation of the microprocessor under the control of the microcode to be stopped and the error conditions to be transferred to the central control unit making use of the same paths as those used fro reporting errors which do not affecte the microcode integrity.

Abstract: ABSTRACT OF THE DISCLOSURE        A magnetically operated valve having a resilient flat-surfaced valve member cooperating with a valve seat is disclosed.  The resilient member is preferably mounted on an armature in a manner to permit relative motion therebetween to allow the armature to gain a predetermined inertia prior to engaging the resilient member so as to aid in overcoming the pressure differential across the resilient member.   Additionally,  the electromagnet thereof acts unevenly on the armature so as to cause tilting movement thereof and a correspond "prying" movement of the resilient member from the valve seat.   The valve may be operated in the normally-opened or the normally-closed mode.  In one embodiment, at least a portion of the armature is provided with a non-magnetic covering or coating,  thereby forming a non-magnetic gap thereon.   In another embodiment, a non-magnetic wear plate is disposed between at least a portion of the electromagnet and the armature.   Such wear plate substantially prevents the armature from contacting and wearing said portion of said magnetic actuating means during the tilting movement of the armature.

Abstract: Abstract of the Disclosure The tape drive device for a magnetic transfer apparatus comprises a master tape and a slave tape wound about a rotary drum and kept in intimate pressure contact with one another by air jetted from a rectangular nozzle formed in an air guide member enclosing and secured to a magnetic head.  During tape running, tension on each tape is controlled to a constant value by tension sensors associated with respective tape reels.  When it is desired upon termination of transfer operation to stop the tape travel, the tape reels for a slave tape presenting a higher inertia are braked first.  The remaining reels presenting a lower inertia are then acted upon and the tape tension sensing means associated therewith are operated to control the tension to a constant value in the course of simultaneous cessation of the tape travel.

Abstract: SUPPRESSIVE FACTOR OF ALLERGY      Abstract of Disclosure A monoclonal hybridoma cell line was constructed for the production of suppressive factor of allergy (SFA). mRNA isolated from the monoclonal hybridoma cell line was identified by  its  ability  to  direct  SFA  synthesis  in Xenopus laevis oocytes. The SFA produced by the monoclonal hybridoma cell line and the translational product of the mRNA in the oocytes was found effective in   inhibiting IgE-  specific  receptor  expression  in  dilutions  greater than 1:1,000   of  the  culture  supernatant.  A  sensitive bioassay  for  SFA  was  developed  using  cultures  of thymocytes  in  which  Lyt-2  cells  were  blocked  with monoclonal   antibodies,   and   subsequent   IgE-specific receptor expression was determined in Lyt-1 cells.

Abstract: EXTRUSION APPARATUS Extrusion apparatus with means to effect movement of a die insert. The die insert has an upstream extension with two planes of movement. For each plane of movement, two thrust means are provided, one at each side of the insert for movement in one direction in the plane. Each thrust means acts at an angle to the required direction of movement of the insert, and produces thrust which is inclined to the direction of movement of the thrust means. In one arrangement, two arms move together, one at each side of the insert extension and place thrust upon the extension. In another arrangement there is cam operation controlled by operating rings surrounding the extension. For movement in each plane, the extension is held in that plane by stationary thrust means which, during movement, controls extension movement in the other plane.

Abstract: Abstract of the Disclosure A   process   for   the   neutral   hydrolytic depolymerization of condensation polymers is described. The process  is  conducted  in  a  continuous  manner  and comprises introducing condensation polymer waste material into  an  aqueous  hydrolysis  zone  at  a  temperature  of between 200° C and 300° C and superatmospheric pressure of  at  least  15  atmospheres.   High pressure  steam  is introduced into the lower portion of the hydrolysis zone underneath the level of the condensation polymer waste material.  The steam serves as the principal source of heat  for the  hydrolysis  zone.   By  being  introduced underneath the level of the condensation polymer waste material,  the  steam  agitates  the  waste  material  to provide  heat  transfer  to  accelerate  the  hydrolysis reaction.  Further, a portion of the steam condenses to provide water which  is  a  reactant  in  the hydrolysis reaction.  An aqueous solution of the product(s) of the hydrolysis reaction is withdrawn from an upper portion of the hydrolysis zone.
