The re-spective system load (11) is connected to the bus line (13) via a terminal unit (12). In dependence on a voltage signal emitted by the central unit (10) and being unique for each respective terminal unit said terminal unit connects the system load (11) to the line (13) or disconnects the load. The central unit detects changes in status of the bus line current and determines out of the said changes the status of the system load (11). For example, the status may be a receipt of the connection of an alarm loop, an indication of the breaking of an alarm loop or an indication of the measurement value of a connected sensor.

Abstract: ABSTRACT OF THE DISCLOSURE           The method and apparatus for storing the data base of gridded type data on a plurality of rotary type data memory devices such that data update to a utilization system, e.g., a computer generated imagery (CGI) processor may be more effectively implemented.          For the generalized case of N rotary data memory devices and for a data base of gridded type data which may be represented by rows and columns of data elements, data elements of each row are "mapped" to the memory devices in accordance with a repetitive and cyclical pattern.  For example, for each row of the grid, the data for each data element of N successive elements is stored on a different one of the N rotary data memory devices and for successive groups of N elements the data is similarly stored in accordance with a repetitive, cyclical pattern wherein each cycle of the pattern includes N successive elements, the data for each of which is stored on a different one of said rotary data memory devices.

Title: Submergible screw-type dental implant
Inventor: LINKOW LEONARD I
IPC: A61C8/00
Filed: 1988-03-15
Granted: 1992-07-14
Abstract: ABSTRACT OF THE INVENTION      A submergible screw-type implant includes a longitudinal channel which directs bone chips towards the base of a bore in the patient's bone in which the implant is installed.  These bone chips promote autogenous rapid regrowth of new bone to securely anchor the implant in place.  In order to be able to position the implant at the most advantageous angle at the edentulous sight, angled abutments for supporting an artificial tooth structure or angularly adjustable abutments are provided. The angularly adjustable abutments may be in the form of a ball and socket joint in which the socket includes an inner casing having a peripheral extension that acts to lock the joint at the desired angle.  Also, the support for an artificial tooth may include a shock-absorbing cushion to prevent some of the forces of mastication from disturbing the implant.
