Abstract: The invention relates to a method for the adaptive control of positionable drives, in which parameters optimised from the travel movement are determined and stored in corrected form during the storage of parameters deposited in data memories. In order, in a method of the generic type, to avoid harmonics in the target position even in the event of a non-cyclical positioning sequence when reducing the clock times, it is proposed according to the invention that a travel distance which is decisive for an operation between its stop points is determined and divided up into calculated numbered distance or angle zones and deposited in a data memory, that with the aid of the distance or angle zones obtained in this way the variables describing travel movements are determined and divided up in each case into a numbered zone system and deposited in a data memory, that a data address is calculated from the number of a zone of a first zone system and the number of a zone of at least one further zone system and that a control parameter field, deposited in a data memory, for the travel movements is driven with the calculated data address and the driven parameters are fed into the control for the purpose of determining control variables. <IMAGE>

Abstract: A method is provided for synchronising concurrent processes in a computer system. Each process has a virtual time. When messages are received and acted upon by a process, and such messages have a receive time greater than or equal to the current virtual time of the process, state consistency can be assumed. If quard checking is enabled, the guards preferably must still be satisfied before the message will be acted upon. If the time of receipt for the message is less than the current virtual time, further state consistency checks are made. Such consistency checks can include checking of variable versions and guards for consistency. If the process state is consistent with the contents of the message, the message can be processed even though the current virtual time is greater than the receive time of the message. The same general approach can also be used within a process having concurrent actions, with shared variables being checked for state consistency using virtual time stamps and variable versions.

Abstract: A multi-stage switch architecture for providing for using a single switching component in multiplicity to create a single network capable of performing a multiplicity of functions. One function of the disclosed network is to circumvent the traditional blocking problems in multi-stage networks by implementing ALTERNATE PATHS between all N and M devices within the same network. This permits a non-blocked path between 2 devices to be found by "rearrangeability" - the act of trying or searching different alternate paths until a non-blocked connection is established. The rearrangeability architecture disclosed is implemented completely in hardware, and is performed automatically and transparently in relation to the software. A second network function permits the ALTERNATE PATHS to be used selectively for GUARANTEED DELIVERY - a special high priority mode of transfer which will guarantee that the connection will be made to an IDLE device as rapidly as possible, even when "Hot" spots in the network traffic patterns are encountered. In addition, the ALTERNATE PATHS provide another function of providing a more fault tolerant network than provided by state-of-the-art solutions. 
     As a result of our inventions we provide a single, unidirectional, unbuffered, multi-stage network capable of doing the total network job consisting of multiple functions. The functional complexity provided usually requires several state-of -the-art multi-stage networks to perform the equivalent job. The single network disclosed here allows traffic in both directions, provides for non-blocking via ALTERNATE PATHS and REARRANGEABILITY, incorporates GUARANTEED DELIVERY and FAULT TOLERANCE, and yet is very compact and inexpensive to implement. In addition, the network is modular in nature and permits easy adaptation to any sized system.

Abstract: A spun-bonded, preferably paper-like, polyolefin sheet (1) or fleece composed of heat and pressure bonded minute polyolefin fibres which is vapour- and gas-pervious but impervious to liquid water and dust, naturally water-resistant and of high tensile and tear strength, is rendered heat-weldable. The material is used for making an applicator for releasing volatile substances, e.g. phosphine derived from metal phosphides at a controlled rate and with complete protection of the contents against liquid water. Excessive local phosphine build-up is avoided. The release rate is controlled by the sheet material itself and by its available surface area. A heat weldable sheet material (1), in particular for the above purposes, is coated, preferably by powder sprinkle coating with a thermoplastic highly porous heat welding bonding layer (2), e.g. EVA, melting so much lower (say 30 to 80°C lower) than the polyolefin fibres that a heat welding seam (6) forms before the fibres melt so that the physical properties of the polyolefin fibres and the gas permeability are substantially retained.

Abstract: Disclosed is a modularly expandable switch-based apparatus which is used to interconnect multiple Personal Computers as nodes of a parallel system. The invention includes a bus-based expansion card which is inserted into a card slot in each of the Personal Computers to provide an adaption from the Personal Computer MicroChannel to the interface to a multi-stage switch network. Thus, the disclosed invention provides a means for extending the MicroChannel architectures to either massively parallel systems or thousands of I/O device taps or a combination of the two. This is accomplished by using electronic switches to interconnect various Personal Computers, where each computer has a unique local bus that can be composed of 1 to 8 MicroChannel taps (card slots). An expansion card containing a bus architecture converter unit is used in one expansion card slot in each Personal Computer to adapt the node to the switch network. The result is that the Personal Computers are fully interconnected and capable of sending data, communications, and/or messages between any two Personal Computers, which become nodes of the parallel system.
