  • Patent number: 4730249
    Abstract: A method for use in a virtual memory data processing system employing a pageable External Page Table data structure for recording current status and disk address information for each virtual page in said system, provides improved system performance when a large number of virtual pages are to be operated on in the same manner. In accordance with the method, each page of External Page Table entries can record a predetermined number of entries (512), depending on the byte capacity of each virtual page (2,048) and the size of each entry (4 bytes). One page of 512 entries correspond to 1 megabyte of virtual storage (512.times.2,048) and also appears as one entry in a pinned External Page Table. The pinned External Page Table is referred to as the "XPT of the XPT," and has the same format as the pageable XPT. A 256 megabyte segment of virtual memory is representable in the XPT of the XPT by 256, 4 byte entries, or one-half of a page.

  • Patent number: 4718008
    Abstract: A method to logically serialize a plurality of independent system events in a virtual memory data processing system. Each event causes interrupt servicing routines to be executed and requires data structures that record the status of virtual pages to be updated. The system events include the interrupt that is generated as a result of a page fault, the interrupt that is generated as a result of a paging I/O completion operation that resolves a page fault, and lastly interrupts generated in response to a supervisory call to a paging service.

  • Patent number: 4662372
    Abstract: By providing two cooperating, pivotable clamping arms, each of which incorporates an elongated, movement controlling plastic portion securely affixed to a die-cast metal or powdered metal section having a clamping face formed therein, a uniquely constructed, pivotable, jaw-clamping surgical instrument is attained. By employing die-cast metal or powdered metal sections, close tolerances and high quality is attained, while the expense of manufacture is substantially reduced. In addition, the integration of the die-cast metal or powdered metal sections with the elongated, movement controlling plastic arms achieves a trouble-free, dependable, inexpensive, disposable surgical instrument wherein the inherent advantages of both materials are optimized.

  • Patent number: 4640039
    Abstract: Apparatus for retaining fishing rods in a boat includes an elongated, flexible belt to which is stitched a pair of opposed, spaced, flexible tapes of the type which includes hook and loop fasteners that matingly interlock when face-to-face. The holder is wrapped around the article in a snug fit relationship and is provided with connectors for mounting on the boat or other support.

  • Patent number: 4297057
    Abstract: The invention is an improvement for a combination mining machine and roof bolting apparatus in which the roof bolting mechanism is pivotable and can be used to install roof bolts in more than one location without moving the mining machine. The improvement is a pivotable canopy which pivots independently of, but in association with, the bolting apparatus. It comprises a canopy shield pivotably and cantileveredly mounted on the upper section of a telescopically-extensible mast. The telescopic mast absorbs all the moment loads, while the hydraulic extension cylinder disposed interiorily of the mast incurs only axial compressive loading.
