    摘要： This disclosure improves data processing system integrity by assigning content types to virtual pages and using the assigned content types to enforce special access rules. The page content types are: (a) any changeable data and/or any executable instructions (current S/370); (b) SCP executable instructions and/or unchangeable data (SENC); (c) SCP restrictively changeable data only (system DO); and optionally (d) application data only (user DO). Page content type designation is done by providing in each PTE two integrity control flag bits called herein SENC and DO. In the first embodiment, the SENC and DO bits are separately coded to respectively control access to SENC and system DO page types. In a second embodiment the SENC and DO bits are combinatorially encoded to obtain four types. A new system integrity state, the SCP state, is provided to protect SENC and system DO page usage. The SCP state is initiated by a hardware interrupt, i.e. a swap of PSWs, and exists only as long as the CPU is fetching instructions from SENC pages. The following new program interrupts are provided to identify when the CPU tries: (1) to execute an instruction fetched from a SENC page while the system is not in the SCP (2) to execute an instruction fetched from a system or application DO page; or (3) to store data into a system DO page using an instruction not fetched from a SENC page. Also while in the SCP state, key zero users are forced to change their access key, whenever necessary, to match the storage key of any page frame prior to changing it.

    摘要翻译： 本公开通过将内容类型分配给虚拟页面并使用所分配的内容类型来强制执行特殊访问规则来提高数据处理系统的完整性。 页面内容类型是：（a）任何可变数据和/或任何可执行指令（当前S / 370）; （b）SCP可执行指令和/或不可更改数据（SENC）; （c）SCP限制性可变数据（系统DO）; 和（d）应用数据（用户DO）。 通过在每个PTE中提供两个在此称为SENC和DO的完整性控制标志位来实现页面内容类型指定。 在第一实施例中，SENC和DO位被分别编码以分别控制对SENC和系统DO页面类型的访问。 在第二实施例中，SENC和DO比特被组合编码以获得四种类型。 提供了新的系统完整性状态（SCP状态）来保护SENC和系统DO页面的使用。 SCP状态由硬件中断（即PSW的交换）发起，并且只要CPU从SENC页获取指令就存在。 提供以下新的程序中断以识别CPU何时尝试：（1）在系统不在SCP（2）中执行从系统或应用程序DO页面提取的指令时，执行从SENC页提取的指令; 或（3）使用未从SENC页提取的指令将数据存储到系统DO页面中。 同时在SCP状态下，如果需要，重点零用户被迫改变其访问密钥，以便在更改之前匹配任何页面帧的存储密钥。

    摘要： A wood joint connector plate is formed of a thin, rigid metal sheet having numerous narrow, elongated, struck-out openings. The struck-out sheet material is bent perpendicularly at each end of each opening to form a pair of opposing reverse-oriented mirror-image teeth. Each tooth is bent about a lengthwise bend line that is offset relative to the central longitudinal axis of its opening to divide the tooth into a narrow portion and a wide portion along its length. The free end of each tooth is formed as an asymmetrical V-shaped tip, whose apex coincides with the bend line, to provide a short leg terminating the tooth narrow portion and a long leg terminating the tooth wide portion. Each tooth is twisted around its bend line so that its tip short leg extends approximately parallel to the axis of the opening and towards its opposing tooth. The tip long leg extends away from its opposing tooth and its opening at an acute angle relative to the longitudinal axis of the opening. The wide portion of each tooth is divided into a tip outer part and a base part by a crease extending from the free end of the tip long leg to about the point where the base of the tooth is intersected by the longitudinal axis of the opening. The base part generally extends at an angle in the general direction of its opposing tooth, and the tip part is formed with a dished depression.

    摘要： A truss plate for connecting together wood members forming trusses, joists, beams and the like construction parts, formed of stiff sheet metal having struck-out teeth extending perpendicularly to the body of the plate. The teeth are struck-out in pairs, leaving an elongated slot between each pair of teeth. The slots, and their teeth, are aligned in numerous longitudinal rows. The rows form groups whose slots are also transversely aligned, but with the slots of one group being longitudinally offset relative to the slots of its adjacent group. The teeth are V-shaped in cross-section and are axially twisted. Their free ends form asymmetrical V-shaped tips. A pair of such plates are arranged in face-to-face contact with the teeth of the uppermost plate extending through the slots in the lowermost plate for closely positioning together adjacent teeth to form a double thickness plate with pairs of double teeth.

    摘要： An apparatus and method for transporting a load upon a vehicle is provided. The apparatus of the invention is a carrier assembly for attachment to a receiver mounted on the rear of a vehicle. The carrier assembly comprises a basket, a hitch for attaching the carrier assembly to the receiver, a riser extending upwardly and outwardly from the hitch, an extension projecting rearwardly from the riser and supporting the basket, and a pivotal connection whereby the basket may be maintained in an upright position or pivoted down and away from the vehicle. The method is carried out using the apparatus to transport loads and by pivoting the basket rearwardly and downwardly from an upright transport position to facilitate access to the rear of the vehicle.
