Title: Shared memory access and data structure access control
Inventor: BAKER BRIAN NEIL
IPC: G06F15/16
Filed: 1991-12-11
Granted: 1998-02-17
Abstract: A method and circuit for granting access to a block of memory in a multiprocessor system having a shared memory is provided.  When a memory request for exclusive access to a block of memory is granted, the starting address for that block of memory is placed in a register bank, thereby opening a semaphore.  The starting address of a memory block of a subsequent memory access request is compared with the starting addresses corresponding to open semaphores within the register bank and access is denied to the requested block of memory if a match is found.  The starting address associated with a request which is denied access is placed in a temporary buffer and the request is later granted access after the corresponding open semaphore becomes closed.  A request which is granted memory access to a memory block which results in an open semaphore, has exclusive access to that block of memory until the semaphore is closed.

Title: Steel studs fixing tool
Inventor: POMERLEAU MARCEL
IPC: E04G21/16
Filed: 1992-06-29
Granted: 1999-08-24
Abstract: The erection of metallic frame dry walls requires, in a first phase, the setting of studs between floor plates and top plates. When such walls exceed 244 cm high, contractors usually call upon two workers to assemble, using scaffolds and common tools, the metallic frame. The invention is a tool that allows an employee working alone, without the use of a scaffold, to erect metallic frames between 244 and 488 centimeters high. Using this tool, a stud can be aligned and fixed permanently between the plates, at the desired location, by two crimping heads at both ends. The tool makes the procedure faster, more accurate and requires less handling than the traditional method.

Abstract: A stuffed mailing envelope is formed from webs of paper. A plurality of insert sheets are constructed from webs of insert paper by variably imaging the insert webs, and then intelligently aligning them and cutting them into aligned sheets, and then folding the aligned sheets to produce a formed insert. A plurality of interconnected envelope blanks are formed from an envelope web of paper, and a plurality of insert sheets (including the formed insert) are collected and placed on each of the envelope blanks while they are interconnected in web form. Then, while conveying the interconnected envelope blanks in web form, the blanks are severed from each other and are formed around the inserts to produce a final mailing envelope containing a plurality of insert sheets. The envelope blank typically has two parallel minor flaps and two parallel major flaps. The envelope is formed by sequentially plough folding over the minor flaps, severing the leading interconnected blank from the next blank so that the major flaps are free, changing the direction of conveyance, applying adhesive to the major flaps, and plough folding the major flaps so that the adhesive comes into contact with the minor flaps and the other major flap.

Abstract: A power steering system (10) for use in a vehicle includes a power steering pump (12) which is driven by an engine (13) of the vehicle.  The output from the power steering pump (12) is connected to a power steering valve (22). The power steering valve (22) is connected with a power steering motor (24).  When the engine (13) is turned off, that is, in a non-operating condition, and the power steering pump (12) is not being driven, the fluid pressure in motor cylinder chambers (40, 42) is prevented from falling below a predetermined pressure to keep seals (64, 66) in sealing engagement with the power steering motor 24. To keep the fluid pressure in the motor cylinder chambers (40, 42) from falling below a predetermined pressure, a one-way valve (70) blocks the flow of fluid from the power steering valve (22) back to the reservoir (16).  A pressure relief valve (72) blocks the flow of fluid from the power steering valve (22) to the reservoir (16) when the fluid pressure in the motor cylinder chambers (40, 42) is equal to or less than the predetermined pressure required to urge seals (64, 66) into sealing engagement with the power steering motor 24.
