Title: Switch stand handle
Inventor: COLLIN GILBERT
IPC: B61L5/02
Filed: 1997-08-29
Abstract: A handle for rotating an actuator on a railway switch stand about an actuator axis, through an arc of approximately 180° between a first position and a second position. The handle has a connector for connecting it to the actuator, a curved grip and an intermediate portion extending between the connector and the curved grip. A weight is secured to the handle between the connector and the curved grip. The handle has a handle axis generally perpendicular to the actuator axis, the handle axis being generally horizontal when the switch stand is in the first or second position. The curved grip extends from opposite sides of the handle axis in a direction generally radial to the actuator axis. The curved grip has a span with a breadth sufficient to allow grasping above the handle axis when the handle is in the first and second positions while avoiding interference with an underlying surface and allowing relatively easy grasping through an intermediate position approximately mid-way between the first and second positions.

IPC: C21D9/46
Filed: 1997-01-24
Abstract: The carbon content in molten steel is adjusted to be a value not lower than 0.001%, and a thin steel strip is made from this molten steel using a twin drum type continuous casting apparatus by means of direct casting. The thus obtained slab is given a reduction of not lower than 10%. The coagulated steel strip is cooled to a temperature not higher than the temperature determined by a function of the carbon content, cooling speed and ratio of reduction of in-line. After that, the steel strip is reheated and then cooled again to a temperature not higher than the temperature determined by the function of the carbon content. Then the cooled steel strip is coiled. In the above process, a metallic sheet, the surface of which is smooth and the metallic structure of which is fine, can be produced.

Title: Pipelined snooping of multiple l1 cache lines
Inventor: GILDA GLENN DAVID
IPC: G06F12/08
Filed: 1998-06-11
Abstract: A cache system provides for accessing set associative caches with no increase in critical path delay, for reducing the latency penalty for cache accesses, for reducing snoop busy time, and for responding to MRU misses and cache misses. A two level cache subsystem including an L1 cache and an L2 cache is provided. A cache directory is accessed for a second snoop request while a directory access from a first snoop request is being evaluated. During a REQUEST stage, a directory access snoop to the directory of the L1 cache is requested; and responsive thereto, during a SNOOP stage, the directory is accessed; during an ACCESS stage, the cache arrays are accessed while processingresults from the SNOOP stage. If multiple data transfers are required out of the L1 cache, a pipeline hold is issued to the REQUEST and SNOOP stages, and the ACCESS stage is repeated. During a FLUSH stage, cache data read from the L1 cache during the ACCESS stage is sent to the L2 cache.
Patent CA-2241125-A1 (CA)
Title: Vacuum assisted debris removal system
Inventor: OLSON SEAN
IPC: G03F7/20
Filed: 1998-06-19
Abstract: A vacuum manifold having a rectangular opening with vacuum access bores connected into the rectangular opening for an illumination field to be projected there through. A vacuum manifold is placed between a photosensitive resist covered wafer and a lens element in a photolithographic tool. The relatively high illumination energy in an illumination field used for projecting an image of a reticle onto a photosensitive resist covered wafer often results in ablated, evaporated, and effused material being coated on the lens element. The vacuum manifold placed between the lens element and the photosensitive resist covered wafer creates an airflow for removing debris or contamination preventing coating of the lens surface. This prevents image quality from degradation over time, as well as reduces downtime needed for cleaning or maintenance of the photolithographic tool.

Abstract: A toilet seat cover for increasing the comfort of a toilet seat, including offering the user insulation from the toilet seat, eliminating of the cold feeling the user often experiences when making contact to the toilet seat with one's buttocks. The toilet seat cover includes a ring shaped stretchable fabric which can be easily positioned over the toilet seat.  The stretchable nature of the material used within the toilet seat cover allows for easy and proper positioning of the cover over a broad range of toilet seat shapes and sizes. The integration of flexible tubing creates a simple anchoring of the seat cover to the underside of the toilet seat. The integration of either elastic band material or string can be used to secure the toilet seat cover once fully stretched over the entire toilet seat. The flexible materials used to construct the toilet seat cover permits the cover to be compactly folded for shipping and transport. The attachment method permits for convenient and quick removal and reattachment to the seat thereby permitting periodic washing of the cover.
