Abstract: ABSTRACT OF THE DISCLOSURE            Machine-implemented text/graphics formatting is based upon a logical page area on a presentation-receiving medium, such as a CRT face, sheet of paper and the like.  Named text and graphics receiving areas are selectively assignable to the logical pages of a document being formatted for visual presentation and are addressable and formattable independent of other formatting in any logical page.   The named areas are machine defined such that one area can have portions thereof automatically assigned to and presented with any arbitrary number of logical pages.  Such areas are managed in a text formatting machine to facilitate formatting headers based upon text contained in a succession of logical pages that are outside the named area.  A first class of such named areas is placed upon the page when formatting to the page is ended, while a second class of such named areas is placed on the page in response to a command.  The place-ment of the second class on a page can result in starting formatting new pages.  Bleed tabs, annotations, and other typographic niceties are machine formattable using such named areas.

Abstract: ABSTRACT OF THE DISCLOSURE A unique building wiring system is disclosed.  When the building framework is completed and the studs and ceiling joists are exposed, the workman places a mark on the floor directly beneath where an electrical outlet box or the like is to be placed.  The workman then drills a vertical hole in the horizontal top plate and directly above the floor mark.  A visual locator tool is positioned in the hole so that it is hangingly supported by the top plate.  The wall and ceiling panels may then be installed by other workmen.  Subsequently, the electrician enters the closed crawlspace where he can easily find the locator by visual observation.  He attaches his electrical wiring to the locator and releases the latter so that it drops down from the hole by gravity, carrying the wiring with it in a generally vertical line.  The electrician then enters the room, finds the mark on the floor, measures up to where he wants the box, cuts a hole in the wall and retrieves the wire, which is directly therebehind, for attachment to the box.  The tool may comprise an elongated heavy bar having an upwardly extending locator portion, a wire attachment element, and a device for manually releasing it from its hanging position on the top plate.

Abstract: INTERNAL BUS ARCHITECTURE FOR A        PRIMITIVE INSTRUCTION SET MACHINE                   ABSTRACT            An internal bus mechanism for implementation in a computing system characterized by having a limited number of primitive general function instructions provided for controlling all system operations.          The architecture of the internal bus mechanism defines a bus instruction format which specifies the bus unit being requested, the operation being requested, and sufficient data to specify the operands necessary to perform the requested operations.  Two basic classes of instructions are provided, one wherein the CPU waits until a requested operation is performed and the other wherein the CPU issues an instruction to a bus unit and proceeds to execute further instructions in parallel with the operation of the bus unit.  If desired, various units of the memory hierarchy may be designated and operated as bus units.  To further the philosophy of a primitive instruction set, the present architecture utilizes a small number of bus unit instructions to replace a large number of additional system instructions which would be necessary if the bus units were architected as part of the CPU itself.  Hardware design and system protocols are disclosed and described for implementing these architectural objectives.

Abstract: ABSTRACT OF THE Disclosure Disclosed is a read channel for an optical recorder.          Data is recorded on the media in a fixed block code.  The data is read and the location of the holes within a symbol are determined for the the odd and even symbol positions separately.  The loca-tion of the hole is determined for an odd or an even hole by using two sample and hold cells to hold the signal value received at a symbol position and compare it to the signal value received at a previous position.  If the comparison results in a new higher valued signal being found, the output of the comparator changes.          If the output of the comparator changes, the address of the change is recorded.  The last such change denotes the location of the symbol position having the highest signal value, which is the address of the hole.  The address of the holes, even and odd, are used to directly convert from the fixed block code to binary.  Two symbols convert to 8 binary bits.

Abstract: ABSTRACT     A silicon substrate having a silicon dioxide bird's head is provided.  A thermal oxide layer is grown on the exposed silicon surface.  A layer, e.g., 4000 A°, of phosphogermanosilicate glass is deposited on the thermal oxide and on the silicon dioxide bird's head. The structure is heated to 950°C, causing a reflow of the glass which results in a planar surface.  The thermal oxide and the phosphogemanosilicate glass are then wet etched at the same rate with a solution of hydrofluoric acid, ammonium fluoride, and deionized water.  The wet etch is terminated when the exposed silicon surface is reached, resulting in a smooth surface as defined by the planar reflow surface.          Other embodiments are disclosed.
