Abstract: ABSTRACT          An apparatus and a method for determining the drainability by permeability measurements.  The apparatus is provided for taking a sample of a suspension, particularly a fibre suspension, e.g. such as flows in a pipe (2), said apparatus including a sampling piston housing (4) connected to the pipe (2) and accommodating a sampling piston (5) which can be displaced into the pipe (2) and has a through hole for forming a sample chamber (9) for taking out a pulp sample.  The housing (4) is in communication with a dilution and mixing chamber (35) including an agitation or mixing device (36), the lower portion of the chamber (35) being closed off by an end member (23) with a screening plate (22).  In the method in accordance with the invention there first takes place measurement on the entire pulp sample, subsequent to which the sample is liberated from its fine fraction by a washing process in a mixing chamber (35), measurement on the proportion of fibre in the pulp sample then taking place, for which purpose the permeability of the pulp bed formed against the screening plate (22) is measured during one or more pressure drops, possibly with inter-mediate slushing with the aid of the mixing device (36) and reformation of the pulp bed.

Abstract: ABSTRACT     In a time division multiplexed digital switching system intercommunication between telephony groups is by way of a serially operated data bus (2).  Allocation of bandwidth on the data bus (2) is on a needs basis under control of a common control responsive (3) to requests from either applications processors or interface modules (10,20).  The interface modules (10,20) receive addressing information from the common control (5) on a serially operated control bus (1) only when a change of status of a communication at least partly affecting that module (10,20) occurs.  Such changes of status include new communication set-ups, communication clear-down, bandwidth increase and bandwidth decrease.  Dynamic re-allocation of bandwidth of the data bus (2) occurs without affecting communications in progress.

Abstract: Abstract A  terminal  controller  system  is  described  wherein several feature cards are plugged into slots on a board, and I/O signal cables are connected between cards and/or remote multiplexors   or   terminals.    A   special   purpose   card identification (ID) bus is driven by the feature cards and received by an ID adapter.   The ID adapter has one select line running to each of the slots on the board.   The ID adapter enables the select lines one at a time, whereby the selected feature cards drive their IDs onto the ID bus.  A processor records the slot population by ID and also can analyze  the  IDs  to  determine  if  a  valid  configuration exists.  The processor then performs a wrap test on each of its ports.  This test alters the ID which it wraps and by comparison with the IDs recorded originally,  this enables the processor to logically establish the physical link to particular cards connected to the ports.

Abstract: ABSTRACT            Stochastic Time Division Multiplexing (STOTDM) is disclosed.          In STOTDM data packets are preceded by a flag word. Each data packet appears in a frame of data packets in a predetermined order. If there is no data to be placed in the packet location, only the flag is transmitted and the data location is allocated to other data. By using a fixed length frame, synchronous data packets can be placed near the beginning of the frame and packets which are not timing sensitive may follow them. A variable length frame may also be used wherein data from a plurality of sources are once again ordered and preceded by a flag word or bit. The flag may be used to indicate whether or not the packet location is filled or this may be determined by control packets. Variable length frames may be accommodated as long as the average bandwidth required to transmit the data does not exceed the channel bandwidth.

Abstract: ABSTRACT OF THE DISCLOSURE         Several types of new microelectronic devices including diodes, transistors, sensors, surface energy storage elements, and light-emitting devices are disclosed.  The properties of these devices can be controlled by molecular-level changes in electroactive polymer components.  These polymer components are formed from electrochemically polymerizable material whose physical properties change in response to chemical changes, and can be used to bring about an electrical connection between two or more closely spaced microelectrodes.  Examples of such materials include polypyrrole, polyaniline, and polythiophene, which respond to changes in redox potential.  Each electrode can be individually addressed and characterized electrochemically by controlling the amount and chemical composition of the functionalizing polymer.  Sensitivity of the devices may be increased by decreasing separation between electrodes as well as altering the chemical environment of the electrode-confined polymer.  These very small, specific, sensitive devices provide means for interfacing electrical and chemical systems while consuming very little power.
