Abstract: The invention relates to a blasting apparatus (10) for activating a plurality of electrical detonators (18) after predetermined time delays. The blasting apparatus includes a plurality of remote electrical delay devices (16.1...16.6). Each device is linked to a detonator (18), and is arranged to be serially programmed with a timing signal, which originates from a central control unit (12) and which determines the time delay. A bidirectional signal harness (14), having ends which terminate at I/O ports (20,22) in the control units (12), serially links the delay devices to the control unit (12). In the event of a fault (27) or discontinuity occurring in the harness prior (14) to programming of the delay devices (16.1...16.6), the discontinuity (27) is detected and the direction of programming along the bidirectional harness (14) is reversed so that those delay devices (16.4,16.5,16.6) which, due to the break (27), cannot be programmed in the initial direction (24), are programmed with timing signals travelling along the signal line in the opposite direction (26). The invention extends to a method of activating a plurality of electrical detonators (18), as well as to the individual delay devices (16.1...16.6) forming part of the blasting apparatus (10).

Abstract: A conical refiner for the refining of paper pulps or the like, comprising a stationary stator blade (2) and a rotating rotor blade (1), with a refining zone (6) formed between the blades so that one end of the refining zone opens to the pulp infeed side and the other end to the delivery side of the refiner. A drawback with currently used refiner constructions is that the pulp fed into the refiner is not refined uniformly, so that the pulp flowing out of the refiner contains both refined fibres and fines and unrefined fibres. In prior art, these have been screened only after the refining. In the present invention, the refiner is provided with a screening unit (4, 7) working on the principle of a pressure screen, the screen plate (4) of the screening unit being of an essentially cylindrical form and coaxial with the refiner blades (1, 2), said screening unit being fixedly connected to the stator blade and located at a desired point in the direction of the pulp flow. The rotor blade (1) has a cylindrical shape in the region of the pressure screen (4, 7) and is provided with a component (3) producing the driving power for the pressure screen.

Abstract: A data storage hierarchy which inherently allows for a level 1 storage file to be uniquely identified across an entire network is disclosed. A directory naming convention is employed which includes an internal identifier and a name for each subdivision of the network. Because each file can be uniquely identified across the network, a single level 1 storage space in a file space, or a directory therein, can be used for the entire network. Also, because of the inherent uniqueness of the naming system, common DASD control files otherwise required to map between level 1 storage files and their level 0 source files can be eliminated.
