Abstract: A method of producing an organo-nitrogen compound by the direct conversion of elemental nitrogen, in which a substrate vapor of a simple organic compound, e.g. propanol is mixed with a carrier gas at least partly comprising nitrogen and the vapor mixture is passed over a catalyst, e.g. of a transition metal, and irradiated with microwave radiation to produce a simple organo-nitrogen compound.

Abstract: A node operating in a network using the International Standard Organization (ISO) High-Level Data Link Control (HDLC) network protocol includes a mechanism for encoding information such that frames including the encoded information can be correctly interpreted by nodes operating in either of the standard 16-bit or 32-bit ISO-HDLC operating modes. The encoding mechanism produces a preliminary frame check sequence by encoding the information in an encoder using a generator polynomial G.sub.48 (x), which is a combination of the generator polynomials G.sub.16 (x) and G.sub.32 (x) which are used to produce frame check sequences for nodes operating in 16-bit or 32-bit modes, respectively. Before the information is encoded, the encoding mechanism sets the encoder to an initial condition using an initializing polynomial I.sub.48 (x). The preliminary frame check sequence is further encoded by adding to it a complementing polynomial C.sub.48 (x). The result is a 48-bit frame check sequence.

Abstract: Computer controlled numbering of consecutive business forms is provided for both computer controlled presses and in the form of a retrofit unit for conventional rotary presses. The retrofit unit includes a disk provided with radially oriented metallic strips of predetermined locations on the disk, and mounted on a suitable shaft of the press. The disk cooperates with a stationary transducer mounted, for example, on a stationary press wall to send signals to the control unit to fire the printer.

Abstract: A communication network consists of end units (EUs) and distribution units (DUs) coupled together by links which may include local area networks (LANs). The units maintain neighbor tables by sending out Hello messages which indicate the unit type and contain the network service access point (NSAP) IDs or addresses of the units. Data messages (packets) mainly originate and end at EUs. An EU maintains only partial routing information about neighbors, while the DUs collectively maintain complete information about all NSAPs. So if an EU wants to send a packet to an EU which is not a neighbour (and sometimes even if it is), it need merely send it to a neighboring DU; that DU, along with the other DUs, must find a route to the destination EU. This invention provides a hybrid unit (HU), which acts as a DU to EUs but as an EU to DUs. The HU provides DU-like message forwarding but only on a local basis within a subnetwork of EUs and HUs.

Abstract: A digital message routing network has at least some nodes at which messages are monitored for accounting purposes. Such a node contains means for generating and compressing accounting digests, each of which consists of a key K representing the nature and route of the message and a value V associated with the message. For each message, a digest is produced in register 30, and copied into a location in a first memory 22D at a location determined by hashing its key; further digests with the same key are compressed into the digest already in that location. A second memory 23D is operated as a cyclic buffer with head and tail counters HDCT 40 and TLCT 41. The address of the head of the buffer, ie the valid area of memory 23D, is included as an index I in each digest in the first memory 22D as that digest is created. Each time a digest is created or changed in the first memory 22D, it is copied into the second memory at the location in the second memory determined by its index.

Abstract: A novel dual mode, downdraft gas range provides a sealed top and sealed gas burners that can be operated effectively in a power burner mode with a downdraft exhaust and otherwise in an atmospheric mode. In the range, a separate and independently operating air/gas supply chamber for each sealed burner is supplied with a controllable flow of gas, and, in the power burner mode, with a controlled forced flow of primary combustion air from a combustion air blower and pressure-adjustable air plenum that supply all air/gas chambers, and each air/gas supply chamber is provided with a gated opening, which is operated to provide an unobstructed flow of primary combustion air from atmosphere in non-power burner operation. The mixture of air and primary combustion air flows from the air/gas supply chamber through a sealed conduit formed to be free of obstructions and abrupt changes in direction with a flow diffuser provided adjacent the gas burner.

Abstract: A message switching network is disclosed which consists of end units between which messages flow. The end units are coupled together directly (via LANs) or via common switching nodes through level 0 links; the nodes are coupled together via level 1 links; and the nodes are grouped into areas which are coupled together via level 2 links. A message entering a node has its destination area code compared with the node's area code, and an area/port table or an end unit/port table is used to look up the output port which is coupled to the end unit, next node in the area, or next area to which that message is to be delivered. Logic circuitry determines the incoming and outgoing levels, and a transition between levels is logged together with certain details of the message. Messages are thus monitored--i.e., their passage is recorded--when they cross levels in the hierarchy.

Abstract: A method for connecting a network so that TCP/IP and OSI 8473 packets may be routed in the same domain. The independence of the addresses is maintained: one device in the network may be assigned only a TCP/IP address, and another device may be assigned only a ISO 8473 address. Furthermore, all of the routers share link state information by using a common link state packet format (such as the ISO 10589 format); thus routes through the network may be computed without regard for the protocols supported by the routers along the route. Where necessary, packets are encapsulated and forwarded through routers which are not capable in the protocol of the packet. In some disclosed embodiments, all of the routers in a given area support a given protocol (or, in fact, have identical capabilities, in which case encapsulation is not required). In these embodiments, the encapsulation is performed by suitable modifications to each router's packet forwarding procedures.

Abstract: A distributed digital data processing system includes a plurality of nodes which communicate over a network. A node maintains one or more objects, each of which may be a file, that is, an addressable unit in the system, such as a program, database, text file, or the like, or a directory which may contain one or more files or other directories. One node maintains a naming service which associates each object in the system with one or more protocol towers. Each protocol tower identifies the object name and a series of entries each identifying a name for each of the protocol layers, along with the communications parameters and address information, to be used in communicating with the object. When a node requires access to an object maintained by another node, it first retrieves from the naming service the protocol towers for the object. The node also maintains a tower identifying the names of each of the protocols over which it can communicate.

Abstract: In a digital communications network, data packets are prevented from making a transit through a domain if such data packets neither originate within nor are addressed to a node within that domain. Only data packets flagged as originating within the domain are allowed to be forwarded out of the domain.

Abstract: A method and apparatus for the automatic production of business forms, wallpaper, newspapers or the like from a web of continuous printing material comprises an endless movable belt having at least one printing station. An image is projected to a surface of the belt. The image is transferred to the web of continuous material at the at least one printing station. Immediately after image transfer, the image is erased from the belt so that a remaining portion of the image may be projected onto its surface at the printing station. In this manner the device appears to provide a printing surface of indeterminate length and so is designed without relation to the image to be projected. A plurality of such printing stations may be arranged in series for color printing. Two more printing stations may be associated with one endless belt for printing two or more colors or two sides of the web.

Abstract: A method and apparatus for the automatic production of business forms, wallpaper, newspapers or the like from a web of continuous printing material comprises a printing station including an endless movable printing device such as a rotating cylinder. An image is projected to a surface of the device. The image is transferred to the web of continuous material at the printing station. Immediately after the printing station, the image is erased from the device so that a remaining portion of the image may be projected onto its surface. In this manner the device appears to provide a printing surface of indeterminate length and so is designed without relation to the image to be projected. A plurality of such printing stations may be arranged in series for color printing. Furthermore, the operation of the printing station and associated activities may be controlled by a pre-selected computer program.

Abstract: Method and apparatus for automatic production of business forms. An image including character data to be included in the form are projected onto a photoconductive surface of a printing cylinder by a plurality of lasers. Toner, in the form of finely grained powder, is applied to the cylinder and the data is thereafter transferred to the web as it is continuously fed past the cylinder. After transfer of the character data to the web, the image is erased so that a new image may be projected onto the cylinder. As a result, printing is not limited by cylinder size, and a continuously varying image may be transferred to the web. As many as four printing or more cylinders may be arranged in series, each applying one of four primary colors to the web. The composition of the forms and the operation of the press are controlled by pre-selected computer programs.

Abstract: In the use of microwave energy to remove moisture from a moving web, such as that moisture contained within transverse glue lines between superimposed sheets of the web for the purpose of holding the sheets together, the web is passed through a serpentine wave guide having a number of serially connected sections spanning the path of travel of the web. The microwave energy takes the form of standing waves within the wave guide, and the peaks of such waves represent "hot spots" of energy concentrations at which points maximum molecular agitation of the moisture is obtained so as to likewise obtain maximum drying effect. If the standing waves are simply tuned until resonance occurs, there is a considerable likelihood that the wave peaks of one section of the wave guide may become lined up with those of the other wave guide sections, hence producing several distinct lines of energy concentrations along the path of web travel.
