Patent CA-2006081-A1 (CA)
Title: Noise reduction method
Inventor: POWELL RONALD L
IPC: B63H1/15
Filed: 1989-12-20
Abstract: ABSTRACT OF THE DISCLOSURE          When there is relative movement, at a speed above a critical value, between the trailing edge of a body, such as a hydrofoil or aerofoil section, and a fluid, the fluid flow tends to form a pattern of discrete swirling vortices.  Vortex shedding at each side of the trailing edge alternately can cause resonance or "singing" of the section.   The effect of this phenomenon is reduced by forming contiguous triangular flat-faced notches in the major surfaces  of the section, adjacent the trailing edge, but leaving the profile of the leading edge substantially undisturbed.   The notches in one major surface are preferably staggered relative to those in the other major surface.

Abstract: A customized fit shoe, and particularly a high-top ice hockey skate, having a plurality of interior inflatable chambers. The chambers are configured and inflatable to different amounts to conform to the contours of the arch and the area below the malleoli of the foot in the shoe. The inflation of the chambers is accurately and easily adjusted through an upper push-to-deflate valve. When thereby adjusted, the concavities of the arch and ankle are filled without restricting the plantar or dorsi flexion of the foot.       An inflatable bladder and valve assembly for providing a customized fit for an athletic shoe is also disclosed herein. A shoe bladder having a plurality of compartments, which are air pressure adjustable through a bladder opening, is fitted into a shoe to individually fit the shoe to the foot. A finger tip actuable valve assembly is connected to the shoe bladder and communicates with the bladder opening. The valve assembly includes a valve housing, a valve seat disposed in the housing and having a conical-shaped seat area, a valve body and a biasing spring. The valve body has an inner portion having a flat surface and the biasing spring biases this inner portion against the valve seat such that the flat area mates against the conical-shaped seat area to hold the valve assembly in its normal closed position. The outer portion of the valve body can be depressed to open the valve and allow air to pass therethrough to inflate or deflate the bladder compartments as needed to provide a custom fit. It can be depressed by a finger tip or when a separable hand pump is attached thereto to open up the bladder opening so that air can be pumped into the compartments.

Title: Method and apparatus for monitoring optical fibers during payout
Inventor: BAILEY WILBUR M
IPC: G01M11/00
Filed: 1990-09-25
Abstract: METHOD AND APPARATUS FOR MONITORING    OPTICAL FIBERS DURING PAYOUT               ABSTRACT OF THE DISCLOSURE         The  turns of an optical fiber paid out from a canister  are  counted,  and  the  signature  of  the optical   fiber   is   measured,  by  monitoring  the electromagnetic  field  of  the charge on the optical fiber  as  it  moves  past  an  antenna.  The optical fiber  follows  a  helical path as it is paid out.  A stationary  antenna  located  transversely  proximate the   payout  region  detects  a  periodic  repeating variation  of the bound and/or free electrical charge associated  with  the  optical  fiber, as the optical fiber  periodically  moves closer to and farther from the  antenna  along the helical path.  Each period of the  variation  corresponds  to  one  turn of optical fiber paid out from the canister.

Title: Resin transfer molding apparatus and process
Inventor: BREW JAMES K
IPC: B29C45/76
Filed: 1991-05-03
Abstract: ABSTRACT           A resin transfer molding apparatus includes a single-shot metering pump which feeds a predetermined amount of resin material to the mold with a single stroke of the pump via an injector assembly which is mounted on the mold.  A closed-loop hydraulic control of the metering pump enables the injection rate and pres-sure of the resin to be varied during the injection cycle to produce a more consistent fill of the mold and eliminate part waviness caused by pressure rise and fall.  The mold-mounted injector assembly and placement of a plurality of valves in the apparatus enables recir-culation of unused resin material back to the supply tank at a temperature sufficiently cool to prevent curing, so that solvent flushing of the apparatus can be eliminated in most cases.  The apparatus is automati-cally controlled by a computer resulting in an in-tegrated automatic apparatus.   The attached injector assembly and valves also permit automatic switching between different resins by resin or solvent flushing of the lines of the apparatus, which eliminates draining and refilling of the apparatus.

Title: Apparatus and method for parallel generation of cyclic redundancy check (crc) codes
Inventor: DRAVIDA SUBRAHMANYAM
IPC: G06F11/10
Filed: 1991-08-29
Abstract: A method and apparatus are disclosed for the efficient generation of cyclic redundancy check (CRC) codes employing CRC generator polynomials of the form (1 + x)~f(x). The efficiency is achieved by independently and concurrently generating in parallel a preliminary CRC code word corresponding to f(x) and a term corresponding to (1 + x) over a message M(x). The term corresponding to (1 + x) is generated in a manner to have either a zero (0) state or a one (1) state. Then, the term corresponding to (1 + x) is used to modify the preliminary CRC code word to obtain an overall CRC code word being generated over message M(x). If the term corresponding to (1 + x) is a 0 state, then the overall CRC code word is obtained by shifting the bits of the preliminary CRC code word once to the left. If the term corresponding to (1 + x) is a 1 state, then the overall CRC code word is obtained by shifting the bits of the preliminary CRC code word once to the left and adding f(x) to the shifted preliminary CRC code word.
