A mono-extruded hemp composite board (EHB) is provided. By combining hemp feedstocks with virgin and/or recycled binder materials and subsequently extruding them into an extrudate sheet, an environmentally friendly alternative to tradition construction materials is created. Secondary feedstocks and waste products from other production streams may be added during the extrusion process to enhance the physical characteristics of the extrudate sheet in addition to reducing the raw material costs and creating a more environmentally friendly construction material. The extrudate sheet produced using such materials is structurally superior to traditional construction materials due to the structural characteristics of dispersed hemp feedstocks; the complete encapsulation of hemp feedstocks in the binder material; and the lower hygroscopic and higher pest and mold resistance properties of hemp feedstocks. A downstream extrusion arrangement may be used to pattern the extrudate sheet and/or create molded shapes that are difficult to achieve in traditional construction materials, increasing the customization potential of final EHB products relative to traditional construction materials.

A ground retention apparatus is provided for deterring the theft of services from an outdoor pedestal. The ground retention apparatus includes a ground stake having a first end attached to the pedestal and a second end opposite the first end for engaging the ground beneath the pedestal. The ground retention apparatus further includes a stop plate secured to the ground stake medially between the first end and the second end. The stop plate defines a hinge line separating a lower portion that is stationary and an upper portion that is movable relative to the lower portion between a first position wherein the upper portion is generally parallel to the lower portion and a second position wherein the upper portion is angled relative to the lower portion. The stop plate prevents the ground stake from being removed from the ground, thereby deterring unauthorized access to the equipment inside the pedestal.

摘要:
Processor apparatus is described for performing binary and decimal arithmetic operations. In performing decimal multiplication with the processor apparatus, to reduce the amount of processing to be done with the apparatus and thereby speed up the performance of the decimal multiplication, the leading zeroes prefixing the highest order significant digit in both a multiplier and a multiplicand are identified, counted and removed. Decimal multiplication is then performed using the stripped multiplier and multiplicand, and to the resultant partial product a number of zeroes are prefixed equal to the number of zeroes originally stripped from the multiplier and multiplicand. The result is the product of the original multiplier and multiplicand.

A logic system is provided for accommodating the exchange of information between two or more communication busses of a data processing system, wherein plural central processing units and plural memory units on independent communication busses may have same logic addresses. Memory and CPU addresses are translated at the bus rate through a multiplicity of flexible address translation ranges to enable a data processing unit on one communication bus to access an apparent contiguous range of addresses encompassing all data processing units on all communication busses.

Apparatus for producing business forms made up of a plurality of webs including a plurality of towers, one for each web with each web being equipped with a plurality of vertically related modules for imparting characteristics to the webs, each module being adapted to create a characteristic in the web traveling therepast, and means associated with each tower for changing at least one characteristic in the web traveling therepast.
摘要:
A logic system in an intersystem link (ISL) unit accommodating the transfer of binary coded information between communication busses in a data processing system is disclosed, wherein dedicated locations in a file register are selected at the bus rate in response to binary coded information received from a local communication bus. ISL transactions to be initiated in response to bus cycle requests thereby are identified. ISL transactions are handled in parallel, and memory transfers are segregated from non-memory transfers to avoid unnecessary delays in memory transfers.
摘要:
A logic system referred to as an intersystem link unit (ISL) is provided for accommodating the transfer of binary coded information between two or more communication busses in a data processing system, wherein information including memory and non-memory read and write requests, CPU to CPU interrupts, peripheral control units to CPU interrupts may be transferred between plural communication busses each supporting plural data processing units including plural CPUs without substantially affecting the bus rate of the individual communication busses. Binary coded information from a communication bus is acquired asynchronously, and plural bus communications of different types are accommodated in parallel. The ISL units further may be dynamically reconfigured to provide for a reallocation of communication bus resources between communication busses.
