Abstract: Abstract:    An array of integrated photosensitive devices is used to lift an image of a printed character or symbol from a document or other surface, process the image to allow for background conditions of the document and referencing it against a desired threshold to produce a black/white video output, in serial form, representative of the image sensed by the array.  Charge transfer devices are used extensively throughout on a single integrated circuit to provide a complete image processing video device on a single integrated circuit chip.

Abstract: ABSTRACT OF THE DISCLOSURE          A multiprocessor information processing system has an additional function to detect a fault occuring in a proces-sor.  A counter is provided for each of a plurality of processors for holding an associated fault supervising code.          The code stored in the associated counter is periodically updated by the associated processor while the update status of the code is supervised on a cycle longer than the cycle of the updating period.  If a fault occurs in one of the processors, the fault supervising code corresponding to that processor will not be updated.  Thus, the faulty processor can be detected by periodically supervising the update status of the fault supervising code.  The supervising operation can be carried out by software or hardware.

Abstract: ABSTRACT OF THE DISCLOSURE A temperature regulating device for electric heating apparatus, of the type comprising a thermostat for controlling the operation of the apparatus.  The thermostat is thermally coupled to a regulation resistor connected in series with a resistor whose resistance varies as a function of temperature.  The latter resistance is thermally coupled to a so-called differential correction first heating resistance and to a so-called shift correction second heating resistance.  These two resistors have different time constants and are energized at the moment the operation of the heating apparatus is initiated by the thermostat and when the latter is put off, respectively.  The device is simple in structure yet efficient and does not require the corrections required by prior art devices.

Abstract: AUXILIARY ROM MEMORY SYSTEM                 ABSTRACT OF THE DISCLOSURE           An auxiliary ROM memory system which is hierarchied for providing for the contingency of additional read-only memory control program storage requirements in excess or in lieu of the predetermined ROM memory provided on-board a micro-processor based central processing unit module, and a read-only memory altering capability utilizing programmable read-only memory to expedite the implementation/installation of changes to the ROM bit patterns.  The alterable PROM storage comprises bulk PROM memory including a first PROM set that is mutually exclusive as to existing on-board ROM memory for addressably branching to code extensions and/or in-line code insertions, and/or a second PROM set that is mutually inclu-sive as to existent on-board and contigent ROM memory for decodably addressing large-scale code overlays thereto.  In addition, the alterable PROM storage comprises patch PROM for addressing, through multi-leveled decoding, small-scale code overlays to the on-board and contingent ROM memory for single in-line bit pattern alterations.  Conflicting memory requests involving addresses recognized by more than one of the supra memory categories, when enabled, are presented to a predetermined hierarchy of memory precedences for resolu-tion thereof.  Each of the enumerated memory categories of the auxiliary ROM memory system may be operative to have its population incremented or decremented without invalidating the above hierarchy of addressing.

Abstract: ABSTRACT OF THE DISCLOSURE A backhoe arrangement is described wherein overcenter forward movement of the boom and boom cylinder provides a transport configuration for the backhoe, and the backhoe operator's view of the bucket is enhanced.  A swing tower is attached to the rear of the machine and serves as a support that embraces an asymmetrically mounted or offset boom assembly wherein the longitudinal axis of the boom and the longitudinal axis of the hydraulic actuator operating the boom are offset from the vertical axis of rotation of the swing tower.  The boom hydraulic actuator flanks the boom in a clearance relationship that permits the boom to assume a substantially vertically directed neutral intermediate position. An offset boom and actuator improves the center of gravity of the backhoe and allows the boom actuator to be protected by the boom.
