Abstract: Title: Phosphorylating agent; a process for the preparation thereof; a process for phosphorylating an organic hydroxyl or amine compound.     ABSTRACT of the disclosure:       The invention relates to phosphorylating agents con-taining at least one protected hydroxyl group and at least one leaving group. According to the invention, a methylsul-phonylethyl group (Mse) is used as the hydroxyl  protecting group. Typical examples of such phosphorylating agents are the compounds (MseO)2POL, (MseO)POLL', (MseO)2PL and (MseO) PLL', in which L and L' are leaving groups.  The invention also relates to processes for preparing these phosphorylating agents and processes for the phosphorylation of organic hydroxyl or amine compounds, in particular nucleosides and (poly)nucleotides.

Abstract: ABSTRACT OF THE DISCLOSURE     A demodulation circuit for frequency modulated signals comprises a variable phase shifter supplied with inputted FM signals, a narrow band pass filter having a bandwidth narrower than that of the Curson band for the FM signals, a frequency discriminator, a filter allowing specific frequency components among the FM detected sig-nals detected by the frequency discriminator to pass, and a phase adjuster for adjusting the frequency components.          The inputted FM signals are passed through the variable phase shifter and the narrow band pass filter and then FM detected by the frequency discriminator, a portion of the detected output signals being passed through the filter and the phase adjuster.  Thereafter, the phase shifter is controlled by the signals, the phase of the FM signals being controlled by the phase shifter in the direction of compressing the frequency deviation for the specific demodulated frequency components in the FM signals, and detected signals are obtained from the frequency discrim-inator.

Abstract: ABSTRACT OF THE DISCLOSURE          A tension rod for the suspension of a conduit has an abutment element threaded thereon for abutment of a spring casing from above or from below.  The spring casing contains a compression spring acting between the bottom of the  casing and a spring disk secured to the tension rod.  An internal sleeve extends from the bottom of the casing and prevents complete compression of the spring.  The threaded on abutment element adjustable limits decompression of the spring.  Through supplementary structure the tension rod can be locked to the casing in a load-independent fashion.

Abstract: A CORING DEVICE WITH AN IMPROVED             CORE SLEEVE AND ANTI-GRIPPING COLLAR                    Abstract of the Disclosure An improved  coring  device  that  incorporates  a nonrotatable  inner  barrel  disposed  within  the  outer  driving structure of the drill string which is coupled to a coring bit. A woven metal mesh  sleeve  is circumferential mounted outside the inner barrel and tucked around its lower end.   The lower end of the mesh sleeve  in the  inner barrel  is in turn connected to a stripper tube which is pulled upwardly during the coring operation.   As  the core  is cut by the coring bit and enters the inner barrel, the woven metal mesh sleeve is disposed about the core and constricts about the core when pulled upwardly by the stripper tube.  The opposing end of the woven metal mesh sleeve is connected to a weight which serves to compress the metal sleeve when outside the inner barrel, thereby increasing its diameter to prevent binding or jamming.

Abstract: ABSTRACT OF THE DISCLOSURE     A  component  insertion  end  effector  for  robotic equipment is disclosed.  The end effector is particularly adapted  for  printed  circuit  insertion  of  electrical component  whose  relationship  between  component  body  and leads varies from the nominal dimensions.  The end effector compensates for variations in body-to-lead configurations to permit components to be precisely placed without damaging the component body or its leads.  The effector comprises a pneumatic gripping mechanism which is coupled to the robot arm by a compliance mechanism.  The compliance mechanism is operable  in  two  states, the  first  state  in  which  the gripping mechanism is freely movable throughout a predeter-mined range of movement with respect to the robot arm, and a second  state  in which the gripping mechanism is  fixedly secured  in  relation  to  the  robot  arm.   An  actuating mechanism is adapted to configure the compliance mechanism into the first state while the gripping mechanism initially grips the component to be gripped, so that the component is gripped without preloading or deforming the component or its leads.  The actuating mechanism is adapted then to configure the  compliance  mechanism  into  the  second  state  for  the component insertion.  A novel release mechanism is provided to release the component from the gripping mechanism after insertion,  which  is  adapted  to  allow  effective  of  the gripping  mechanism  insertion  and  release  in  a  densely populated board.     Other features and improvements are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE     A process and apparatus for extrusion of a mixture of vegetable bits with a binder, particularly wood chips with a weather-resistant binder, comprising precompressing in a compression chamber of an extrusion press the mixture by a compression stroke transverse to the extrusion axis, the compression stroke being delivered by at least one precom-pression piston, wherein the improvement comprises mixing the mixture prior to precompression with elongated bits which will be acted on by an orienting influence in a known way so that the elongated bits are deposited substantially parallel to the extrusion axis, and performing the precom-pression of the outer layers of the mixture with a reduced precompression ratio so that the bits oriented prior to precompression remain fixed in position during the subsequent extrusion stroke.  Preferably the elongated bits in the mixture are oriented by free fall of the mixture through a plurality of upright, thin-walled bars of approximately equal height positioned above the compression chamber during filling of the extrusion apparatus by a mechanical hopper moving to and fro over the bars continuously.  The bars may be vibrated and the hopper moved intermittently instead of continuously as an alternative.

Abstract: METHOD AND APPARATUS FOR SHARING OPERATORS         AMONG ASSISTANCE SYSTEMS            Abstract An arrangement for serving an operator assistance request detected in a first operator assistance system from an operator position in a second operator assistance system.  If a first operator assistance system is overloaded or has no attended operator positions, the two operator assistance systems cooperate to establish a connection between the customer requesting operator assistance and the operator position in the second system. The attending operator at that position keys information into the operator position for transmission to the first system.  Responsive to this data, the first system enters data, such as billing data, into its records, and sets up connections, such as a connection for a person-to-person call, in its switching network.  The arrangement can be used to transfer operator assistance requests at night, during overload, or to specialized operators not available at the first office.  The arrangement can also be used on a permanent basis, to transfer all operator assistance requests, when a serving team of operators cannot be economically justified for the first office.
