Abstract: A method of transmitting data packets in time slots on a communication network having first and second unidirectional buses which are oppositely directed and a number of access units coupled between the buses is described. The method including the steps of forming a distributed queue of data packets by queueing in each access unit the therein received data packets to be transmitted on the first unidirectional bus, transmitting a request flag on the second unidirectional bus by each access unit for each data packet in the queue in the respective access unit, keeping track in each access unit of all request flags passing said access unit on the second unidirectional bus and transmitting a data packet from the queue in access unit if a predetermined number of empty time slots has passed said access unit on the first bus. At the time a further data packet arrives in an access unit and is added to the queue therein a request flag is transmitted on the second bus by the access unit. The further data packet is transmitted by the access unit in the first empty time slot on the first bus after a number of free slots on the first bus have passed the access unit. The number of free slots is equal to the total number of data packets in the distributed queue at the time of arrival of the further data packet in the access unit, such that only those data packets are transmitted before the further data packet (first-in/first-out principle).

Abstract: ABSTRACT OF THE DISCLOSURE:            There is disclosed a process for producing  high-temperature resistant and  flame-retardant  paperlike materials based on polyimide polymers of the general formula   which material has a weight per unit area of between 20 and 1,100 g/m2, a LOI-value of at least 32 % O2 and a TG point of at least 300°C. A pulp consisting of an aqueous suspension of polyimide fibers and, if desired, polyimide fibrids having structural units of the general formula (I) is processed on a paper machine to a nonwoven, which is wet-pressed and dried. The polyimide fibers are used in a disintegrated state, i.e., having fiber lengths of from 0.01 to 120 mm. Paperlike materials according to the invention having a weight per unit area of between 60 and 290 9/m2 are producible by contacting a manipulatable sheet-like structure of polyimide fibers with a polyimide solution, drying and, if desired, compacting the same.

Abstract: METHOD FOR CONTROLLING SEDIMENTATION       IN AN EBULLATED BED PROCESS        (D#79,086-F) ABSTRACT OF THE DISCLOSURE     In an ebullated bed process, it has been found that in switching from one sediment yielding feedstock to a second sediment yielding feedstock that the transient sediment concentration is 5 to 8 times the steady state concentration.      Such transients have caused unit shutdowns with lost production time.    A method has been found which avoids these high transient sediment concentrations.  Second feedstock is added incrementally (1 vol% to 2 vol% of the final rate) over the period of a week or more and sediment in the product analyzed.      After full second feedstock rate is achieved, first feedstock is reduced incrementally with sediment analysis.  Higher unit utilization is achieved with the corresponding increased yearly production.

Title: Process of detecting and compensating position errors occurring during the manufacture of a web consisting of a multilayer non-woven fabric
Inventor: ERHARDT DIETMAR
IPC: D04H1/74
Filed: 1989-12-21
Abstract: ABSTRACT          It is desired to detect and to compensate position errors occurring during the manufacture of a web consisting of a multilayer non-woven fabric by means of a laying machine, in which a web consisting of a monolayer non-woven fabric is supplied to a conveyor belt transversely to the direction of travel of said belt and is laid onto said belt by a reciprocating motion to form a multilayer web.  For that purpose, the measured value signal is analyzed by machine, preferably by a Fourier transformation, for errors consist-ing of periodically occurring fluctuations of the signal amplitude and the velocity of the conveyor belt and/or the velocity at which the monolayer non-woven web is supplied and/or the width in which the monolayer non-woven web is supplied and/or the width in which the non-woven web is laid onto the delivering belt are automatically controlled to minimize the periodic fluctuations of the signal amplitude.

Abstract: PHA.40-559                                      08-08-1989 ABSTRACT: COMPACT VALVE ACTUATOR     A pneumatically powered valve actuator is disclosed including a valve actuator housing, a main piston reciprocable within the housing along an axis and a pair of auxiliary pistons fixed to and movable with the main piston. The main piston has a pair of oppositely facing primary working surfaces. A pair of air control valves reciprocable along said axis relative to both the housing and the main piston between open and closed positions control air flow from a pressurized source causing the main piston and the pair of auxiliary pistons to move. Each auxiliary piston forms, in conjunction with a surface of the corresponding air control valve, a variable volume annular chamber. The variable volume chamber function during the early portion of piston movement to apply a reclosing force to the air control valve and during a latter portion of the piston movement to vent air compressed by the piston during damping. This venting of the residual air is in an axial rather than a radial direction.
