Abstract: 6791 CAN     INVENTOR:  KLAUS ARNDT               INVENTION: APPARATUS FOR LOCKING A DRIVE SHAFT FOR THE            ELEVATION OR AZIMUTH SIGHTING MOVEMENTS OF THE SIGHTING DEVICE OF AN OBSERVATION PERISCOPE     ABSTRACT OF THE DISCLOSURE     An apparatus for the locking of a component or part free of play, especially a drive shaft in a null position, but also other elements, such as a machine part.  The drive shaft can be rotated about its lengthwise axis and positioned in a predetermined rotational position.  In the null position the drive shaft provided with an impact or contact element is locked by means of a first locking element constructed as a hard layer and a second locking element constructed as a resilient contact or impact member, each of which locking elements are rotatable into the rotational plane of the drive shaft.  The drive shaft is locked by the locking elements in such a manner that the first locking element and the contact or impact element attached to the drive shaft as well as the second displaceably mounted locking element are successively acted upon or contacted by the action of the restoring force of a spring which is effective at the second locking element.         The locking apparatus renders possible, particularly for adjusting the optical axes, an exactly reproducible essentially play-free locking of the drive shaft provided, for instance, for the azimuth or elevational movement of a sighting or aiming device of an observation periscope arranged above a armoured vehicle roof or cover arrangement of a combat vehicle or the like.

Abstract: ABSTRACT Apparatus is disclosed for processing sparse vectors in a tandem or parallel processing environment.  Sparse vectors are those vectors stored in memory with their zero-valued operands deleted.  They have a corresponding order vector of bits whose state indicates the order of zero and non zero operands in a corresponding expanded vector.  The apparatus fetches the order vectors n bits at a time, n corresponding to the number of tandem processors, and counts the number of one bits.  This number of operands is then fetched from memory.  The apparatus aligns and orders the fetched sparse vector operands, inserts zero operands where appropriate, and forwards the resulting portion of the expanded vector to the tandem processors for processing.

Abstract: Abstract of the disclosure:  A process for the preparation of branched block copolymers of from 60 to 95 % by weight of a monovinyl-aromatic monomer and from 40 to 5 % by weight of a conjugated diene by polymerizing the monomers in an inert solvent in the presence of a monolithium-hydrocarbon as the initiator, wherein, in a first process stage (a), from 50 to 80, or where necessary at most 90, % by weight of the total amount of monovinyl-aromatic compound are polymerized to virtually complete conversion in the presence of a relatively small amount of the mono-lithium-hydrocarbon.     This stage is carried out by starting with from 30 to 70 % by weight of the vinyl-aromatic monomer and adding from 70 to 30 % by weight in the feed, during the polymerization, in such a way that the polymerization temperature, which at the start of the polymerization is from 30 to 40°C, is kept at from 45 to 70°C, with use of reflux cooling.    After all the monomer feed has been added the reaction temperature is lowered to 30- 40°C by evaporative cooling.    In a second process stage (b), an additional amount of initiator is added to the reaction solution, after which from 1 to 30 % by weight of the total amount of monovinyl-aromatic monomer can be added, the sum of the amounts of monovinyl-aromatic monomer added in the first and second process stages being at most 90 % by weight of the total amount of monovinyl-aromatic monomer.     The monovinyl-aromatic monomer added in the second process stage is polymerized to virtually complete conversion, employing the tempera-ture profile described for stage (a).    In process stage (c), the remainder of the monovinyl-aromatic monomer and all of the conjugated diene are added, at least predominantly in the form of a mixture, and poly-merized so that the reaction temperature does not rise above 90 - 110°C.     Finally, after virtually complete conversion of the monomers, and preferably without prior cooling, a suitable liquid polyfunctional coupling agent is run in undiluted and the mixture of the linear block copolymers obtained, which still contain active terminal lithium-carbon bonds, is coupled, with stirring, to form branched block copolymers.        The products prepared according to the invention are used for injection molding.

Abstract: POWER UP RESET CIRCUIT FOR A DIGITAL SYSTEM          Abstract of the Disclosure A power up reset circuit, for use with a digital system having a power supply with a long power up interval, includes a voltage reference circuit, a voltage detector and a pulse generator.  The voltage reference circuit provides a reference voltage at either the instantaneous power supply voltage or a predetermined voltage, whichever is less.  The voltage detector generates a power ON signal a period of time after the power supply voltage exceeds the predetermined voltage.          The pulse generator asserts a reset signal which continues from a time before the power ON signal is asserted and for a substantially predetermined interval of time thereafter.  The power up reset circuit is particularly useful in cases where an unrestrained power up switching load in the associated digital system would otherwise prolong an already long power up interval characteristic of the power supply.                             - i -

Abstract: Abstract of the Disclosure An interface mechanism between a pair of processors such as a host processor (70) and a processor (31) in an intelligent controller (30) for mass storage devices (40).  The interface utilizes a set of data structures employing a dedicated communications region (80A) in host memory (80).  There are two layers to the interface - a transport mechanism and a port; the latter is hardware for communicating via the transport mechanism and a process implementing a set of rules governing those communications.  Commands and responses are communicated as packets over the host's I/O bus (60), to and, from the communications region (30A) through a pair of ring-type queues (80D and 80E).  These rings, and the rules governing their operation, permit the host and controller processors to operate at their own speeds, without creating race conditions of other timing problems while obviating the need for a hardware interlock capability on the I/O bus.  The ring entries point to other locations in the communications region where commands and responses are placed.  The filling and emptying of ring entries is controlled through the use of an "ownership" byte or bit Fig. 8, 278; Fig. 313, 133, 135, 137, 139) associated with each entry (Fig. 38, 132, 134, 136, 138).  The ownership bit is placed in a first state when the message source (i.e., controller or host) has filled the entry and in a second state when the entry has been emptied by its receiver.  A message oriented credit system provides flow control and prevents more packets being sent than a ring can accept.      Interrupt generation is reduced because strings of commands and responses can be communicated without need for interrupting the host processor for each one.  The interface mechanism requests interrupts primarily only when its command ring undergoes a state change from full to not-full and when its response ring undergoes a state change from not-empty to empty.  A "FLAG" bit in a preselected register controls the generation of interrupt requests.      During a multi-step initialization procedure, the integrity of the communications path between host and controller is checked out.  In particular, the communications path includes a register and information is written to and read from the register to vecify correct operation of each bit of the register.  As part of the write-read processs, certain host-specific parameters, such as the sizes of the ring-type queues and their starting addresses is sent from the host to the controller.      Capability is shown also for allowing repeated access to the same host memory location for successive reads, writes, or any combination of the two.  With bus adapters which impose rigid sequencing rules which do not allow reads and writes to be mixed, the adapter channel is pruged between successive accesses to the same location.  The port requests the purge and it is executed by the host.
