Abstract: ABSTRACT OF THE DISCLOSURE        A rotatable coupling member for attachment to an end or between the ends of hose or tubing to be used in the con-veyance of a fluid under pressure.  The coupling member comprises a first body member having means disposed at one end thereof for attaching the first body member to a source of fluid and a substantially tubular shaped insert extending away from a second end thereof into an axially aligned receiving bore disposed at a first end of a second body member that pro-vides a fluid interconnecting relationship to a second end of the second body member having means disposed thereat for attach-ment to a source of fluid.  An annular retainment groove having a cross-sectional shape capable of being altered as a result of an axial compressive force being applied to the insert is disposed in the first body member insert outer wall.  An an-nular retainment receiving groove is disposed in the inner wall of the receiving bore and is axially aligned with the insert retainment groove so that retainment means such as, for example, an arcuate shaped wire, originally disposed in the insert retainment groove, is caused to extend radially outwardly therefrom into the second body member retainment receiving groove as a result of axially compressing the insert to provide a rotatable, interlocked relationship between the first and second body members.

Abstract: ABSTRACT OF THE DISCLOSURE     A data processing system in which the operating logic thereof is arranged to provide for an overlapping of the access, or "fetch" operations such that access to a second memory module can be obtained by a processor unit before a data transfer has been completed with respect to a first memory module and read-out of the second memory module can process during the rewrite cycle of the first module to reduce the overall processing time.  Such operation is made even more effective by arranging the system to utilize memory interleaving techniques.  Further, the system of the invention can provide for multi-processor operation with a single memory system by the use of appropriate time-sharing techniques wherein processors can be operated in time-phased pairs, suitable multiprocessor control logic being arranged to provide for preselected priority allocations among the multiple processors to permit the most effective management of the multiprocessor system.

Abstract: L'invention concerne un procédé de prise de vue et de projection sur un écran se présentant essentiellement sous la forme d'une coupole sphérique, susceptible de reconstituer un champ image de valeur angulaire élevée. Le procédé selon l'invention est caractérisé en ce qu'il consiste à effectuer la prise de vue sur un film à l'aide d'un objectif du type fish-eye incliné par rapport à l'horizontale comportant un pincement progressif de l'image vers sa périphérie suivant une loi de répartition linéaire et susceptible de fournir un champ angulaire de grande ouverture pouvant atteindre 220.degree. et à inscrire sur le film, en vue de la projection, des images circulaires tronquées dont la troncature est orientée longitudinalement et placée au voisinage d'une des rangées de perforation du film. La projection est effectuée sur l'écran en utilisant un téléobjectif de projection et un miroir convexe placé au voisinage immédiat du centre de la coupole et dont l'axe de symétrie est incliné du même angle que l'objectif de prise de vue, et adapté à l'écran. Lors de la projection, le téléobjectif de projection est placé à une distance convenable du miroir convexe de façon à permettre à l'image réelle de chaque point du film de venir en coïncidence avec un point correspondant de l'image virtuelle incurvée formée sur l'écran par le miroir convexe, et les aberrations créées par le miroir convexe sur les bords de l'écran sont compensées afin d'obtenir sur celui-ci une image fidèle de la perspective de l'objet photographié.

Abstract: IMPROVED PELT FAT REMOVAL APPARATUS                      MELVILLE R. REID                 ABSTRACT OF THE DISCLOSURE         Improved apparatus is disclosed for increasing the output of a machine for removing fat from the inside of an animal pelt, such as a mink pelt.  In such machines, pelts are mounted inside out on rotatable elongate mandrils, and a cutting head resembling a router trims the fat from the pelt.          The improvement includes a control assembly attached to the cutting head for pivotal movement thereof to control the depth of cut.  The control assembly has a flexible extension which permits the cutting head to move freely longitudinally along the mandril.  The control assembly also has a toggle joint and a lever operably coupled thereto to reduce the effort of pivoting the cutting head.  The depth of out is therefore con-trolled with reduced effort using a lever in a fixed location on the machine. A reciprocating element controls the longitudinal position of the cutting head.  The reciprocating element is operated by foot controlled drive means including a motor driven reversing clutch.  Also, stops disengage the clutch to limit longitudinal movement of the cutting head therebeyond.

Abstract: COAL LIQUEFACTION PROCESS EMPLOYING INTERNAL HEAT TRANSFER        ABSTRACT OF THE DISCLOSURE           A coal liquefaction process wherein a feed coal-solvent slurry is preheated in a thoroughly back-mixed preheater zone (46) and then passed to a dissolver zone (58).  Hot hydrogen (70) is introduced to the process downstream from the preheater zone at or in advance of the dissolver zone and exothermic hydro-cracking reactions occur in the dissolver zone (58). A dissolver zone effluent stream (76) is passed through a vapor-liquid separator (78) and separated hot dis-solver vapor (80) at process pressure is vented through the preheater zone (46) wherein it is quenched to provide direct transfer to the preheater zone of the exothermic heat generated in the dissolver zone.  The preheater zone is continuously vented (86) to provide rapid removal of cooled vapor from the preheater zone and from the process, advantageously leaving an accumu-lation of liquid in the preheater zone boiling between the temperatures of the vapor-liquid separator and the preheater zone at process pressure.  Venting of hot vapor generated in the exothermic dissolver zone through the preheater zone to accomplish direct internal heat exchange within the process requires continuous venting of cooled vapor from the preheater zone independently of removal of slurry from the preheater zone.  Such independent venting of the preheating zone is feasible because of the introduction of hydrogen to the process downstream from the preheating zone.
