Title: Light-tight package and packaging method for photosensitive web roll
Inventor: CHASE GREGORY A
IPC: G03C3/00
Filed: 1992-09-18
Abstract: LIGHT-TIGHT PACKAGE AND PACKAGING METHOD FOR PHOTOSENSITIVE WEB ROLL                       ABSTRACT OF THE DISCLOSURE      A package light-tightly enclosing a photosensitive web roll for use in cooperating apparatus comprises an opaque leader joined to the web and wrapped circumferentially at least twice around the roll and a pair of thin, readily foldable, disk-shaped, opaque end caps covering the roll ends.  Each end cap has an inner annular portion that is folded into and sealed inside one of the roll core ends and an outer annular portion that is folded over the corresponding roll end periphery and onto the adjacent lateral edge portion of the first leader convolution.  A pair of opposite lateral edge portion recesses extend inwardly from the leader opposite lateral edges, by an amount slightly exceeding the folded-over end-cap outer-annular-portion width, at a circumferential site on the leader where the first leader convolution ends.  A narrower medial portion of the leader between those recesses can thus pass freely between the folded-over outer annular portions and thereby permit the second leader convolution to be wrapped circumferentially around the folded-over outer annular portions.  The folded-over outer annular portions of both end caps are thus light-tightly trapped between the opposite lateral edge portions of the first and second leader convolutions, thereby light-tightly enclosing the web roll without having to seal or adhere the leader to the end caps, and without significantly increasing the web roll length.

Abstract: In a method for the detection of faults in a length of textile fabric the length of fabric is continuously scanned by means of an electro-optical sensor head. Light detectors located in a strip-form sensing zone of the sensor head are assembled in groups and emit group-specific fault signals. These fault signals are analysed multi-dimensionally for the identification of spot faults and/or long faults, the criteria for analysis being the signal amplitude, the signal length, the recurrence of the signals and their periodic repeat at each revolution of the machine. Display, control counter devices and suchlike are energised as a function of the result of the analysis.

Title: Suspend/resume capability for a protected mode microprocessor and hard disk, and idle mode implementation
Inventor: FOSTER MARK J
IPC: G06F1/08
Filed: 1992-05-15
Abstract: A portable computer system includes a protected mode microprocessor (311) capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. When running a multi-tasking operating system where an application program is being executed in a restricted mode, certain types of processing can be carried out after the unrestricted mode is entered due to the predetermined condition, then the interrupted application can be resumed with the restricted mode back in effect. An idle mode feature can automatically decrease and increase the speed of the processor clock (387) when user activity stops and later starts again, to conserve power.

Title: Flexible shaft-coupling
Inventor: WOLF FRANZ JOSEF
IPC: F16D3/62
Filed: 1993-08-26
Abstract: Abstract of the Disclosure The invention concerns a flexible shaft coupling in which the torque transmission takes place by means of elastomer shackles or a circumferentially     closed elastomer ring between the two shafts to be coupled. In the invention, the coupling components in the form of separate anchoring plates are all arranged in a single radial plane of the coupling, whereas the radially outward-pointing elastomer shackles are mounted to enclose the coupling. For predetermined torque to be transmitted, this design allows minimal outside dimensions of the flexible shaft coupling, as a result of which these couplings are especially applicable to wheel driveshafts of motor vehicles.
