Abstract: On an end part of the nozzle (23) is produced a joint surface (24) of frustoconical shape whose axis coincides with the axis of the nozzle, which has a half-angle at the apex close to 45 DEG  and a cross-section decreasing in size towards the end of the nozzle (23). On the wall (20) member is produced a joint surface (25) of frustoconical shape corresponding to the shape of the joint surface (24) of the nozzle. The joint surfaces (24, 25) are placed so as to coincide, the nozzle and the wall member are welded with an electron beam in a single run and without additional metal, along their joint surfaces (24, 25) starting at the side of the wall (20) onto which opens the widened part of the joint surface (25) of the opening (22). The invention is applied in particular to the fastening of nozzles (23) to a nozzle-carrier belt (20) of a pressurised water nuclear reactor vessel.

Abstract: RCA 84,965 Abstract In a video display apparatus having an on-screen display feature (OSD), a vertical deflection circuit includes a vertical deflection winding coupled to a DC blocking capacitor.  A deflection amplifier responsive to a sawtooth signal is coupled to the vertical deflection winding at an output terminal. A vertical sawtooth voltage generator that generates the sawtooth signal is coupled to an input terminal of the amplifier for driving the output stage at a vertical rate in a sawtooth manner to generate a sawtooth deflection current in the deflection winding.  The sawtooth generator includes a capacitor that, during normal operation, is charged in a sawtooth manner via a resistor for developing a sawtooth signal. During a transition interval that follows a user initiated channel selection command, the frequency of the sawtooth signal becomes smaller.  To prevent OSD character repositioning, a switch couples a first voltage via the resistor to the capacitor that causes the rate of change of the sawtooth signal and that of the deflection current to become smaller than during normal operation.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus for selecting a particular node from a plurality of nodes connected to a common bus to allow the node to use the bus. The nodes have a pre-determined priority. After initially enabling the nodes, the bus is monitored for a bus idle condition. It is then determined which of the nodes are enabled message nodes, which are enabled nodes that have a message to send on the bus. There is then arbitration between the enabled message nodes after the bus is in the bus idle condition for a first period of time, such that the enabled message node having the highest pre-determined priority among the enabled message nodes is disabled for arbitration purposes, and also at the same time selects a target and performs a transfer. This procedure is repeated until all the enabled message nodes have been disabled. Thereafter, all of the nodes on the bus are enabled when the bus is in the bus idle condition for a second period of time, which is longer than the first period of time.

Abstract: PHONE MANAGEMENT SERVER FOR USE WITH       A PERSONAL COMPUTER LAN Abstract The present invention relates to a technique for providing phone management (PM) services to personal computers (PCs) which are end user of a PC-only Local Area Network (LAN) by logically associating voice terminals of a separate voice and data Network, e.g., a Private Branch Exchange (PBX), with the PCs. To provide the PM services, a PM server device is provided as an interface between the PC and PBX Networks onto which are bridged appearances of the logically associated voice terminals. The PM server device includes hardware and PM server application software that perform routing and translations between (1) PM messages of the PC-LAN which use a first PM signaling protocol, and (2) PM messages of the PBX which use a second signaling protocol. Each end user PC of the PC-LAN that is logically associated with a voice terminal on a PBX network includes PM user application software that provides a PM user interface and terminates the first PM signaling protocol. Typical PM services that can be performed at the PC are displaying calling/called party identification, retrieving and displaying messages on the PC screen, and placing voice calls from a PC-based directory.

Abstract: A friction welder has a reciprocator (1) with two chambers (7 and 8) each containing hydraulic fluid and separated by a dividing wall 16).   A piston (14) on a driven rod (13) is slidable in a hole in the dividing wall  and  supports  a  carrier (28)  to  which  a  first component (36)   is  secured.    Tow  additional  rods (9 and 10)   extend  through  the   chambers.     Enlarged portions (11)  thereof  extend  through  holes  in  end walls (4 and 5)  of the chambers.   The additional rods are  caused  to  reciprocate  with  fixed  amplitude  by Scotch   cranks (23   to 26,    and 31)   driven   by   a motor (30).  The relative phases of the Scotch cranks can be varied by axial movement of a sleeve (35) which engages splined shafts of the cranks, one of sets of splines (35)  being  helical  and  the  other  straight. When  the  additional  rods  reciprocate  in unison they cause  local variations  in  the interior space of the chambers which cause reciprocation of the piston.  The amplitude of reciprocation of the piston is less than that of the additional rods but the force exerted is greater.   The  first component is held in frictional contact with a stationery second component (37) so that frictional heat is generated between them.   When the cranks are 180° out of phase the piston ceases to move and    the  components    become    welded    together. Reciprocation  of  the  piston  and associated parts  is balanced  by  a  balancer (2)  somewhat  similar  to  the reciprocator,  while  reciprocation  of  the  additional rods and their extensions (16  and 17)  in the balancer are balanced by pivoted counterweight (46).

Abstract: Abstract A multi-classification information security  method to  prevent information in  a  computer  information  system  with  one  of  a plurality  of security classifications to be written onto an input/output means with a non-compatible security classification.  The method may also prevent information with  one of a plurality of security classification from being accessed by  a user  with a different  classification.   A   detector  means   located  in   the  computer input/output device detects the classification of the input/output means which is indicated by color or bar code indicia located  on the  input/output means. This input/output means classification is compared with the  classification of the  information.   When  the classifications  correspond, information  can be written to the input/output medium.

Abstract: A phthalic anhydride product having a particle configuration made up of a mixture of spheroids, needle-like crystals, and amorphous particles is produced by feeding molten phthalic anhydride at a temperature between 131 DEG and 155 DEG  into a spray nozzle in a closed cycle congealing chamber. The molten phthalic anhydride is discharged from the spray nozzle into a co-current or counter-current flow of inert gas at a temperature between - 10 DEG  and 70 DEG C, in order to congeal the product, which is then removed and transferred to a hopper or other storage means. For nozzle orifices having a diameter from 1 to 4 mm, discharge pressures of between 10 and 300 pounds per square inch are employed. In an especially preferred embodiment, the needle-like crystalline configurations are disjoined from the spheroids, thereby increasing the bulk density of the product, which in all embodiments exhibits the combination of superior flowability and more rapid dissolution, when compared with prior art products.
