Title: Switch element for fibre channel networks
Inventor: PUROHIT ROBIN
IPC: H04B10/291
Filed: 1995-07-14
Abstract: A system for facilitating data communications in a fibre channel network is presented. The system comprises a fiber optic switch element which enables implementation of a Fibre Channel network by permitting selective interconnection of a plurality of fiber optic channels. The fiber optic switch element permits both circuit and frame switching. The switch element comprises a switch module which is connected to at least one fabric-port within the fibre channel fabric. The switch module allocates switching bandwidth. A path allocation system, whichis connected to the switch module, generally directs frames of data between the at least one fabric-port to other fabric-ports located within the fabric. A channel module comprising a port intelligence mechanism is disposed between the switch module and the fabric-ports. An element controller provides centralized fabric management.

Title: Gravity precision sand casting of aluminum and equivalent metals
Inventor: GRENKOWITZ ROBERT WALKER
IPC: B22C9/08
Filed: 1995-09-28
Abstract: A technique and accompanying apparatus to promote increased yield, improved surface finish and microstructure, and faster cycling time for precision-sand casting process.  Aluminum products are cast by: (a) forming a precision sand mold, devoid of risers and/or vents, and a gating system consisting of a gravity feeding sprue and one or more runners effective to carry molten metal from the sprue only to the bottom of the mold cavity; (b) planting a flow modifier in the gating system between the sprue and mold effective to convert the flow into laminar quiescent flow; and (c) filling the gating system with molten aluminum metal at a rate faster than 4 pounds/second as permitted by the laminar flow that more rapidly fills the mold and acts as a heat sink to prevent a drop in temperature of the in-coming molten metal and thereby increase yield as well as minimizing cycle time.
Patent CA-2160509-A1 (CA)
Inventor: FROEHLICH JAMES P
IPC: A61M16/00
Filed: 1995-10-13
Abstract: The invention relates to continuous positive airway pressure (CPAP) respiratory therapy apparatus for treatment of apnea, hypopnea and other sleep disorders, and particularly to a standby control for automatically operating an air blower in CPAP apparatus. A blower is connected through a hose and a mask, such as a nasal mask or a nasal cannula, to the patient's respiratory airway. Initially, the blower is in a standby mode in which it is either turned off or, preferably, operated at a low speed. When a patient starts breathing through the mask, the blower is automatically switched to an operating mode. In the operating mode, the blower may be controlled to initially supply a low air pressure to the mask which either is increased after a sufficient time delayto allow the patient to fall asleep or is increased in response to the detection of a respiratory event such as apnea or hypopnea. If patient breathing through the mask ceases because the mask has been removed or otherwise is no longer sufficiently sealed to the patient's airway, the blower is automatically returned to the low pressure standby mode. If the patient does not begin breathing through the mask within a predetermined time, the blower is stopped. An optional recorder measures the total time that the patient is breathing through the mask or the total time that the blower is in the operating mode to provide the prescribing physician or technician with patient compliance information.

Title: Walker
Inventor: DOYLE BRIAN
IPC: A61H3/04
Filed: 1995-11-10
Abstract: A walker is constructed by interconnecting a pair of side frames each formed by a front leg and a rear leg interconnect by a bridging member. The bridging member is constructed to pass the front leg therethrough and clamp it into position and pivotably mount the rear legs on a pivot spaced from the front leg. Each of the rear legs pivot between a collapse position and an operative position wherein the leg bears against a stop surface in the bridging member. The frames are interconnected by spacers and handles are telescoping received in the top ends of the front legs. This construction permits manufacture of different sized walkers by simply reducing the effective lengths of the legs.

Filed: 1996-04-30
Abstract: The present invention provides a magnetic steel sheet containing, on a weight basis,  0.2 to 6.5% of Si and 0.03 to 2.5% of Mn,  having a crystallographic texture wherein the density of aggregation of {100} planes parallel to the surface of the sheet is not less than 10 times that of non-oriented crystal grains. and having a demanganized layer in which the concentration of manganese decreases from the interior of the sheet toward the surface of the sheet, wherein the ratio between the concentration of manganese in the surface portion of the sheet and that in the mid depth portion of the sheet is not more than 0.90 and wherein the maximum ratio of reduction in the concentration of manganese within the demanganized layer is not more than 0.05 wt%/ µm.  Magnetic characteristics of the magnetic steel sheet are further improved by adopting the average grain diameter 0.25 to 10 times the thickness of the sheet and by applying to the sheet a tension smaller than the elastic limit of the sheet in a direction parallel to the surface of the sheet.  By employing an appropriate ratio of reduction in the Mn concentration, a relatively high magnetic flux density is obtained without a sharp increase in magnetic flux density. and core loss reduces, thereby providing a non-oriented or doubly oriented magnetic steel sheet having excellent magnetic characteristics and blanking performance.
