摘要： A method of symptom compression involves a symptom compression device receiving binary coded information including bits signifying symptoms present in the course of each operating cycle at selected points in an integrated logical network, microprocessor or the like. The device includes a first register, a second shift register, an EXCLUSIVE OR logic network, and a display. The binary coded information is received on parallel inputs of the first register and applied from parallel outputs of the first register to a set of inputs of the EXCLUSIVE OR network, a second set of inputs which is connected to at least some parallel outputs from the second shift register. A set of outputs from the EXCLUSIVE OR network is connected to parallel inputs of the second shift register. In each cycle, the bits in the second shift register, which accumulate information representative of symptoms, are shifted in one direction and are recirculated. The display is connected to the parallel outputs from the second shift register. In a second embodiment, a third shift register receives the output from the EXCLUSIVE OR network. A multiplexor selectively applies signals from the outputs of the second or third shift register to the second set of inputs. The bits in the third shift register, which also accumulate information as to symptoms, are shifted in the opposite direction. A second display is connected to the outputs of the third shift register.

摘要： A multicolor inked ribbon cartridge for an impact serial printer comprising a ribbon housing body and two arms protruding from such body to allow the interposition of a ribbon portion between a printing head and a printing support for the whole length of the platen when the cartridge is rotatably attached to the frame of an impact serial printer by means of two lateral cylindrically-shaped projections provided on the body of a cartridge thus permitting rotation of the body around a common axis of said cylindrical projections, parallel to the platen. The cartridge rotation around such axis and therefore the positioning of a suitable multicolor band between the printing head and printing support is assured by a cam actuated by a motor and interacting with the body of such cartridge. The cartridge is further provided with a string made tight between the ends of its arms upon the multicolor ribbon portion which is interposed between the head and printing support. Such string is provided for slidably and rotatably attaching a ribbon positioning and guiding element, which follows the cartridge rotation, and at the same time, is suitably coupled to the carriage of the serial printer, to follow the printing head in its transverse shift in order to assure a correct positioning and tensioning of the subsequent zones of the multicolor ribbon contacted by the printing head.

摘要： Rack housing for user reconfigurable EDP system comprised of a frame frontally opened to allow the insertion of a plurality of printed wired artworks (PWA) each one in a rack position. A protection ruler fixed, with the aid of tools, to the open frame front prevents the extraction from the frame of the PWA constituting a basic EDP configuration. Substitution of optional PWAs into the system via selected rack positions is accomplished by suitable undercuttings selectively arranged on the projecting edge, and by one or more panels covering the open front and removably fixed. Each panel is easily removable without need of any tool, so that the protection ruler is positioned between frame and cover panel (or panels) and cannot be removed without the previous removal of the cover panel (or panels).

摘要： In a data processing system wherein a memory is comprised of an unknown plurality of memory blocks of a basic capacity, arranged in an unknown plurality of modules which have an unknown capacity multiple of the basic capacity, a method addresses the memory location which involves the selection of the module containing such locations by use of a directory having a plurality of addressable locations. The initial loading of the directory with codes corresponding to the real constituent of the memory is performed by writing into the directory locations a binary code assigning the related memory blocks to a hypothetical first module, writing test codes into memory locations each belonging to a different block, reading out the contents of the same memory locations and comparing such contents with the test codes to determine if a first module is present and if such memory locations and the pertaining blocks belong to the first module, writing into the directory locations whose related memory block do not belong to the first module a binary code assigning the related memory blocks to a hypothetical second module, writing test codes into memory locations each belonging to a different block assigned to the second module, reading out the contents of the same memory locations and comparing such contents with the test codes to determine if a second module is present and if such memory locations and related memory blocks belong to the second module, and repeating the above operations for further subsequent modules.

摘要： A serial printer is disclosed where the printing is performed by a printing head (22) mounted on a carriage (21) movable along the printing line, a transparent leaf (36) mounted on the carriage presses the printing support (25) (paper) against a platen (24) around the zone where the impression is performed thus considerably reducing the noise and vibration generated by the printing support vibrations during the printing.Preferably, the leaf is provided with a window (45) wherein the impression is performed in order to press the printing support against the platen all around the print zone. As the leaf is transparent, it does not preclude the visibility of what is printed. Besides, as the leaf is mounted on the carriage, when the carriage is in its travel position, the leaf does not interfere with the loading of the printing support in the printer.

摘要： In a tape transport of the type where tape traveling between a pair of tape reels is selectively moved past a recording/readout station by externally controlled capstan means, a novel, semiautomatic system is provided for loading the tape into the transport. In accordance with the present invention, this is accomplished by manual insertion of the tape into a first tape path and by subsequent, stepwise automatic loading into a second tape path when predetermined operating conditions in the transport are present. Transport disabling means, normally operative in the absence of the aforesaid operating conditions, are inhibited during the tape loading operation, becoming operative again when the transport is fully loaded and ready for normal operation. Apparatus for loading tape in this manner avoids the time delays and reliability problems of fully manual loading systems, as well as the high cost and lack of reliability in certain critical areas of fully automatic tape loading equipment.
