Abstract: A technique called "Adaptive Pacing" permits a receiving node, in a computing networking, to change the size of an information window during an active session. To effect the change, the receiving node sends an "Isolated Pacing Message" (IPM) to the sending node. Thereafter, the sending node adjusts the window size to conform with a window size value in the IPM. The IPM includes a type field, a reset window indicator and a next window size field. There are three types of isolated pacing messages. Two of the messages are used by the receiving node to control the flow of data; while the third message is used, by the sending node, to confirm the beginning of a new window and the ending of an old one.

Abstract: This invention relates to a device for removing short fibers from a mass of fibers. A pair of perforated cylindrical bodies (20, 21) are opposed to each other with a predetermined spacing defined therebetween, and static electricity is applied across the perforated cylindrical bodies. A suction-wise removing device (23, 24) is installed in at least one of the perforated cylindrical bodies. The initial end of a transfer conveyor (29) is located on the surface of one perforated cylindrical body adjacent the opposed region. Short fibers contained in the mass of fibers fed to the opposed region by a feeding device (18) are drawn into the suction-wise removing devices through the through holes (20a, 21a) in the cylindrical bodies by the action of electrostatic force and suction air currents. The mass of fibers having the short fibers removed therefrom are oriented by electrostatic force and transferred by the conveyor while being maintained in this oriented state.

Abstract: The invention relates to a drying plant with its own energy supply, in particular a fluidised-bed drier with built-in heating surfaces 4 for condensing heating steam, the bulk goods of the drier 1 being fluidised, by the waste gases of a steam generator 2 and/or the vapours conducted in the circuit, before they are conducted off into the open. The steam produced in the steam generator 2 is expanded in a back pressure turbine 3 and the expanded steam is condensed in the heating surfaces 4 of the drier 1. In the event that coal or another fuel is used as goods to be dried, part of the dried bulk goods is thus burned in the steam generator, as a result of which the plant is energy-autarkic. <IMAGE>

Abstract: A method of controlling the rotary speed of a single-phase ac-motor, for instance a motor driving a circulation pump, said motor comprising a power winding and an auxiliary winding connected in series with a capacitor. A switch is connected in series with the power winding for connecting and disconnecting the ac-voltage at or directly subsequent to a zero crossing. The method comprises connecting the auxiliary winding permanently and controlling the switch to connect the power winding in a predetermined sequence given by a predetermined connection time periodically re­peated with a predetermined period. Both the period and the connection time are chosen as an integral multiple of one half cycle of the applied ac-voltage, i.e. the supply voltage, and the connection time is less than or equal to the period. This results in an improved even rotation of the motor as well as a decrease in acoustic noise. Moreover, losses are considerably less and the switch can be held small.

Abstract: A fast access digital audio message system is described in which message storage capacity is provided on memory mod­ules (2), the number of modules (2) being expandable to in­crease the capacity of the system. Each module (2) has digi­tal memory (10) which is organized with a plurality of message units (56), each message unit (56) including a number of successive memory bytes for storing respective messages. A desired message is accessed by stepping through the message units (56) to the desired location having the start of the desired message, skipping the intervening bytes. The message is then read out at the system clock rate. The memory (10) of each module (2) is preferably addressed by a corresponding counter (4) which has a lower order control input (CL) for counting up at one memory byte per count, and a higher order control input (16) for counting up at an accelerated rate of one message unit (56) per count. A microprocessor controller (64) causes each of the memory modules (2) to access the location of the desired message through a fast access line (16), and then causes the desired message to be read out from its particular module (2) while readout from the other modules (2) is inhibited.

Abstract: The object of the invention is a plug connection for electrical cables, having a first and a second plug connector part. The two plug connector parts contain a plurality of contact elements and coded- fitment elements for external coding. The coded-fitment elements must be effectively connected to one another on assembly of the two plug connector parts. The two plug connector parts are connected to one another on their longitudinal sides in each case via plates (51) and a housing containing the one plug connector part. The plates (51), which extend on both sides of the plug connector parts in each case over the length of the shorter plug connector part, have latching hooks (62) on one side, each of which grips over one edge on the housing, and legs (14) on the other side, which project into plug sockets on the other plug connector part. The coded-fitment elements can be fitted to the plate (51), into a position which projects with respect to the plane of the plate, at the same distance as the longitudinal pitch of the contact elements, in which position they project over the plane of the plate approximately by the depth of a depression which is opened for producing the effective connection to the other plug connector part. <IMAGE>
