Inventor: TROIANI VINCENT F
IPC: B60T17/22
Filed: 1994-05-06
Abstract: An  electro-pneumatic  brake  system  for  a  railroad freight car is  integrated with the  existing pneumatic freight brake system by utilizing the air stored in the emergency reservoir to supply brake cylinder pressure via the exhaust passage of the pneumatic control valve, which is maintained in release position during electro-pneumatic brake operation.  The electro-pneumatic brake system fails to a release mode, so that the brakes on an individual car that experiences a power loss do not apply.  In the case of a power loss in the electro-pneumatic system,  due to a train  break-in-two,   the  pneumatic  brake  system  is automatically operated by the consequent loss of brake pipe pressure to provide a back-up brake, while at the same time interrupting the control valve exhaust path via which the electro-pneumatic brake is communicated with the brake cylinder.

Title: Method for performing disk array operations using a nonuniform stripe size mapping scheme
Inventor: NEUFELD E DAVID
IPC: G06F11/10
Filed: 1992-12-18
Abstract: METHOD FOR PERFORMING DISK ARRAY OPERATIONS USING A NONUNIFORM STRIPE SIZE MAPPING DEVICE            ABSTRACT OF THE DISCLOSURE    A method and apparatus for improving disk performance in a disk array subsystem.  A nonuniform mapping scheme is used wherein the disk array includes regions having varying sizes of data stripes.  The disk array includes a region comprised of data stripes having a stripe size that corresponds to the size of the internal data structures frequently used by the file system, in addition to a region comprised of a number of data stripes having a larger stripe size which are used for general data storage.  When a write operation occurs involving one of the data structures, the data structure is preferably mapped to the small stripe region in the disk array having a size which matches the size of the data structure.  In this manner, whenever a file system data structure is updated, the operation is a full stripe write.  This removes the performance penalty associated with partial stripe write operations.

Patent CA-2129627-A1 (CA)
Inventor: KAVEHRAD MOHSEN
IPC: G02B6/28
Filed: 1993-02-05
Abstract: In N x N optical couplers, such as are used in local area networks and backplanes of telecommunications and computer equipment, a BRAGG volume diffraction device (101; 801; 1101; 1601) couple light beams between the inputs and outputs. The number of gratings in the diffraction device is reduced by means of so-called "grating degeneration", whereby one grating can be shared by at least two wave pairs at the same time. In order to achieve this reductin, the directions of light waves in the dielectric slab (or the lateral positions of fibre ends) are suitably arranged. In other embodiments, a reduced number of gratings is achieved by using a "sandwiched" structure which uses multi-layered dielectric slabs (801A, 801B; 1101A, 1101B). Both embodiments may be combined in the one coupler.

Patent CA-2146228-A1 (CA)
Inventor: TERADA YASUHARU
IPC: A44B19/30
Filed: 1995-04-03
Abstract: In an automatic lock slider for a slide fastener, a yoke accommodating a locking pawl and a leaf spring has a pair of inwardly directed projections, and a generally C-shaped, narrow rigid strip has on its upper edges a pair of taper surfaces corresponding to the respective projec-tions.  As the taper surfaces are guided by the projections, the pawl keeps its suitable posture during the assembling of the slider, and the pawl acts reliably while the automatic locking mechanism is either operative or inoperative.  The locking pawl is small in width and has one leg portion to be inserted in a groove of the outer surface of a connector of a slider body.  The result is that the number of pressing steps is reduced to minimize press traces on the surface of an upper wing of the slider body so that press traces are prevented from coming out on the slider surface though the yoke is smaller in width compared to the conventional one.

Abstract: 2148460 9411557 PCTABScor01 A process for hydraulically needling a web of stapled fibers into an unbonded flash spun web made of continuous plexifilaments to form a spunlaced nonwoven fabric. The web of staple fibers is positioned against the unbonded flash spun web and then hydraulically needled such that the staple fibers are embedded into and entangled with the unbonded flash spun web to form a spunlaced nonwoven fabric. Optionally, the spunlaced nonwoven fabric can be thermally bonded to maintain or increase the permeability of the fabric. Thermal bonding can be used to control the level of permeability depending on the end-use desired. Spunlaced nonwoven fabrics made by the inventive process are particularly useful in filtration applications (e.g., vacuum cleaner bags) when thermal bonding is employed and as bulky, downproof and featherproof barrier liners for garments, sleeping bags, pillows, comforters and the like when thermal bonding is not employed.
