Title: Communications network

Granted: 1992-11-17
Abstract: COMMUNICATIONS NETWORK                     ABSTRACT OF THE DISCLOSURE      Data messages are transmitted between host data processors and a communications processor.  Data messages from a communications processor are transformed for the host processor to which the message is assigned.  Data messages from a host processor are transformed for the communications processor.         Protocol is established between (a) untransformed data messages from the communications processor and transformed data messages for the communications processor, and (b) untransformed data messages from each host processor and transformed data messages for each host processor.  A device interface connects a plurality of host processors to a plurality of buses, each bus being connected to one communications processor.  The device interface handles the protocol, transformation and control function in parallel so that messages between a given host processor and terminal connected to a communications processor are processed through a device interface.  The result is that user terminals and host applications are managed as "pools" of logical devices with dynamic session assignment.

Granted: 1991-08-06
Abstract: ABSTRACT OF THE DISCLOSURE    A steam generator is provided for steam baths, e.g. steam cubicles.  The steam generator includes a column-shaped housing.  An inlet is provided in the housing for entry of ambient air to the housing.  An electrically-heatable water bath is situated in the housing for boiling water therein.  A ventilator is provided for causing ambient air to enter the housing via an inlet for delivering the air to the water bath and, in use, for pushing air into the water bath.  Means are provided for heating the water bath, such means for heating being sized to bring water, when in the bath during operation of the generator, to a temperature near the water boiling temperature.  A hot air-steam mixture leaves the water bath and exits the generator housing to the ambient environment.

Abstract: A process for the preparation of linear polymers of carbon monoxide with one or more olefinically unsaturated compounds,  in which polymers the monomer units occur alternatingly, is disclosed.          According to the invention, a mixture of carbon monoxide with one or more olefinically unsaturated compounds is contacted in a reactor with a solution of  a palladium-containing catalyst composition, wherein the catalyst composition is added stepwise to the reactor. 25 to 85% of the total amount of the composition is present in the reactor at the outset of polymerization and the remainder of the catalyst composition is added only after the polymer concentration has reached a value of at least 0.2 g per 100 g polymer suspension.          The polymers prepared according to the invention have a bulk density considerably higher than similar polymers known from the prior art, which makes more efficient their preparation,  refining, storage, transport and processing.

Title: Film cassette
Inventor: FAIRMAN PATRICIA D
IPC: G03B17/30
Filed: 1989-03-08
Granted: 1992-09-22
Abstract: Abstract Film Cassette In a 35mm film cassette (1), the leading end (45) of a film roll (37) coiled about a film spool (5) is located within the cassette shell (3). The film spool (5) is comprised of two pieces (77, 79) constructed to telescopically receive one another.  Each spool piece (77, 79) includes a radially extending flange (51, 53) normally disposed adjacent one of the opposite sides (61, 63) of the film roll (37).  When the film spool (5) is initially rotated in a film unwinding direction (U), a rotation-responsive cam device (83, 85) coupling the two spool pieces (77, 79) automatically moves one spool piece axially toward the other piece to cause the respective flanges (51, 53) to clamp the film roll (37) at its opposite sides (61, 63).  As a result, the leading end (45) of the film roll (37) will be rotated past a stripper-guide (93) which strips the leading end (45) from between the flanges (51, 53) and guides it through a light-trapped opening (25) in the cassette shell (3).  Thus rotation of the film spool (5) in the unwinding direction (U) will advance the leading end (45) to the outside of the film cassette (1).

Abstract: A network having a single medium with a transmitting channel which is translated at a head end to a receiving channel.  All the nodes of the system are coupled to both the transmitting channel and the receiving channel in a logical bus system with a physical tree-type layout.  Time slots are defined by a timing mark generator, with each node detecting the timing marks on only the receiving channel.  The time between each timing mark defines a frame, with each frame consisting of a plurality of time slots.  Each node determines a skew time necessary for that node to transmit in a specified timeslot when it only receives the timing marks on the receive line and not on the transmit line. Each node is a different physical distance from the head end, resulting in each node transmitting at a different time relative to the received timing mark due to the differences in transmission time to the head end and back.  Accordingly, each node transmits a test signal and measures the time after the transmission until it receives the test signal.  This time, designated a skew time, is used for transmissions of information.   Each node transmits at a time equal to the skew time in advance of the beginning of the timeslot following a timing mark.

Abstract: A process of degassing and decarbonizing is directed to a process for performing vacuum degassing non-deoxidized or slightly deoxidized molten steel utilizing RH process or DH process.  The process includes blowing of oxygen or oxygen containing gas toward the surface of the molten steel in a vacuum chamber for promoting decarbonizing reaction.  The process further includes a step of combusting CO gas in the vicinity of the surface of the molten metal at a timing, in which the concentration of (CO + CO2) in an exhaust gas is higher than or equal to 5% by volume and at a CO2/(CO + CO2) ratio in the exhaust gas is approximately 0.3.  Heat generated by combustion of CO gas is utilized for compensating temperature drop of the molten steel.
