Patent CA-2112001-A1 (CA)
Inventor: EVAN SHABTAI
IPC: H04L29/06
Filed: 1993-12-21
Abstract: A general purpose programmable communications interface designed to support a wide variety of serial synchronous and asynchronous communication protocols. A universal protocol communications (UPC) interface is designed to operate on a VME bus in conjunction with a CPU board which contains the application software that utilizes the communications capabilities of the UPC interface. Per channel DMA is available on input/output lines of the interface together with bit level control for message processing so that a variety of bit oriented communications protocols may be supported by simple reconfiguration of the receiver/ transmitter of the programmable UPC interface. In a preferred embodiment, a dynamically variable bit length shift register is used to organize the received and transmitted data into serial packets of the appropriate size on a per channel basis independent of the actual width of the shift register.      Reconfiguration for different protocols is accomplished by simply changing a bit count value stored in a bit counter which counts the number of serial data bits received or transmitted in each data word by the dynamically variable bit length shift registers of the transmit and receive circuitry.

Filed: 1994-10-14
Abstract: A roofing shingle is conveniently formed from a square sheet metal blank. One corner of the blank is provided with a pair of open ended, back to back U shaped slots transverse to a diagonal passing through that corner. The two sides intersected by the slots are downwardly turned to form a small margin, and the other two sides are upwardly turned to form a margin of similar width to the downwardly turned sides. The corner is also downwardly folded above the slots to form a margin of similar width to the other margins, and below the slots it is folded so as to be generally parallel to the central area of the shingle. A shingle support preferably of foamed sheet polystyrene is disposed on the under surface of the shingle. The shingles are laid course by course on a pitched roof in a diamond configuration, a shingle of an upper course engaging the respective downturned edges of two adjacent shingles of a lower course in the U shaped slots to lock the lower corner of the upper shingle mechanically in position. Nails or screws may be used to secure portions of the upper shingle remote from the mechanically locked corner. A downwardly turned side of the upper shingle and an upwardly turned side of a lower shingle will form a seal to resist the penetration of driven rain and capillary action. The shingled roof has an appearance of thickness, while heat transference between shingles is generally reduced in comparison to flat shingles.

Patent CA-2140321-A1 (CA)
Inventor: MARSCHKE CARL R
IPC: B31C11/02
Filed: 1995-01-16
Abstract: A method and apparatus for manufacturing recyclable paper pallets utilizes spool-shaped laminated supports which are wound on a spool-shaped mandrel utilizing adhesive coated paper strips. In one aspect of the invention, the spool-shaped laminated supports can be glued to conventional upper and lower pallet skin sheets also made of paper material, such as corrugated paperboard. In another aspect of the invention, the spool-shaped pallet supports are utilized in a system in which the pallet is integrated directly into a prestrapped load. In this system, a slip sheet is strapped directly to the bottom of a load and the slip sheet is glued directly to the upper faces of an array of pallet supports, sufficient to support the load and to provide the spacers or standoffs for subsequent insertion of lifting equipment, such as a lifting fork, beneath the load. The inherent rigidity of the strapped load may be sufficient to compensate for the lack of rigidity of the thin paper slip sheet. If the supported load does not have adequate structural rigidity, a lower structural skin sheet may be glued to the lower faces of the pallet support array to provide the strength in compression needed to lift the palletized load. The system of the present invention provides wide flexibility allowing pallet systems to be utilized which are adequate to support the intended load with a minimum use of materials. The spool-shaped supports may be manufactured on-site and the pallets formed on the in-line system processing the material loads. An alternate pallet support is made from a strip cut from a continuous web of single face corrugated paperboard.

Title: Coincident activation of pass transistors in a random access memory
Inventor: VINAL ALBERT W
IPC: G11C11/412
Filed: 1993-08-30
Abstract: The pass transistors in a random access memory array are activated only upon coincident (simultaneous) selection of both the associated row and the associated column of the memory cell;  otherwise, activation of the pass transistors is prevented. Thus, when a word line is selected, only the pass transistors in the memory cell corresponding to a simultaneously selected bit line is active, rather than all of the pass transistors pairs connected to the word line. Transient power consumption during word line selection and deselection is thereby reduced. Coincident pass transistor activation may be obtained by providing a column select line for each column of the memory array, and gating means in each cell which electrically activates the associated pass transistors only upon simultaneous selection of the associated column select line and the associated work line, and for preventing activation of the associated pass transistors otherwise. When the column select lines and gating means are used, shared bit lines may be provided in the array. A single shared bit line may be used between adjacent columns of cells since only one of the columns will be selected by the column select line. A high density memory design is therefore provided.
