Patent CA-2145126-C (CA)
Title: Pipe laying system and method
Inventor: FULLER FRANK E
IPC: E03F9/00
Filed: 1995-03-21
Granted: 1998-07-28
Abstract: A system  for  simultaneously lining and  cleaning an existing sewer pipe, and for laying horizontal pipe without digging a trench, includes a planetary gear assembly mounted on a drilling rig.  A liner pipe or outer pipe which is to be laid underground is placed over an inner auger,  with the forward end of the liner pipe located behind the auger drill bit.  The opposite end of the auger is attached to the sun gear of the planetary gear assembly; and the outer pipe is secured to the ring gear of the assembly.   The auger is rotated in one direction, causing the outer pipe to rotate in the other direction;  and the pipe and auger are pushed simultaneously through the pipe to be lined or through the soil.  Once a section of auger and liner pipe have been pushed in place, the planetary gear assembly is disconnected from the auger and the liner pipe, new sections of auger and liner pipe are connected to the existing sections at one end, and to the planetary gear assembly at the other end.   The process is repeated until the desired length of pipe is inserted into the ground.  After completion of insertion of the pipe, the pipe is disconnected from the planetary gear assembly and the auger is withdrawn through the pipe for use with a subsequent installation.

Title: Resource allocation synchronization in a parallel processing system
Inventor: GRICE DONALD GEORGE
IPC: G06F15/177
Filed: 1995-04-03
Granted: 2001-05-01
Abstract: A method and system for synchronizing allocation of resources in a parallel processing system.   At predefined time intervals, each user application executing in a parallel processing system is given a higher priority such that the system resources are allocated to the user applications instead of the operating system services.   This high priority lasts for a predetermined amount of time.  When the time has elapsed,  each priority value is lowered,  thus giving the operating system services an opportunity to execute.

Title: Online placement of video files on disks in a server environment
Inventor: DAN ASIT
IPC: H04N7/173
Filed: 1995-06-29
Granted: 2000-09-12
Abstract: A placement system and method wherein the placement of programs such as movies, audio programs, audio-visual programs and similar types of data, is determined as a function of the bandwidth-space ratio (BSR) of each disk in the system. The BSR of a disk is defined as the bandwidth of the disk divided by the space. The BSR of the programs on the disk is the total expected demand for the programs divided by the space recruited to store the programs. In a preferred embodiment, a Video Placement Manager (a software task operating under a server's main control program) places the programs on the disks so as to best match the BSR of movies stored on the disk and the BSR of the disk, thus minimizing the waste of both disk bandwidth and disk space.

IPC: B61H15/00
Filed: 1996-03-28
Granted: 1999-05-04
Abstract: A self wear compensating valve for controlling flow of a fluid employs seals for sealing between relatively moving parts.          In one of the parts, an annular recess is formed.  A conformable sealing member is placed in the recess, and a spring biased to expel the conformable sealing member and press it against a sealing surface on the other part is provided.  An O-ring placed on the outside of the conformable sealing member prevents leakage of fluid through the recess outside of the conformable sealing member.  As the conformable sealing member is worn away, after many cycles of the valve, the spring continues to press it against the sealing surface, while the O-ring continues to prevent leakage of fluid outside the conformable sealing member.          A rotary valve suitable for railroad brake applications is provided, which controls flow of fluid from a supply to the brake cylinder, and provides for exhaust of fluid from the brake cylinder.  The valve has a supply port, a delivery port and an exhaust.  In one position, the supply port is connected to the delivery port through a passage in the rotor.   In another position, the delivery port is connected to the exhaust port through a passage in the rotor.  In a third position, the lap position, all the ports are blocked by the relative position of the rotor and the housing.  Proportional control of fluid flow is provided by elongating the ports on the mating surfaces of the rotor and the housing in the direction of rotation.

Title: Composition for producing phosphine-containing gas
Inventor: FEJA FRANZISKUS HORN
IPC: B01J19/14
Filed: 1996-06-07
Granted: 2001-10-09
Abstract: A metal phosphide composition is disclosed for generating a mixture of phosphine and diluent gas(es), presented ready for use in a hydrolysis process or apparatus in the form of a free-flowing particulate metal phosphide material composed of loose particles of said metal phosphide essentially free of metal phosphide dust, essentially free of hydrolysis retarding agents and essentially free of hydrophobic substances in the form of coatings or hydrophobising additives. In use the hydrolysable metal phosphide, preferably magnesium phosphide, is released directly into liquid water under an atmosphere of gas inert to phosphine. The generated mixture of phosphine and inert carrier gas, e.g. CO2, can be used as such or is diluted into a gas mixing chamber with air to a concentration below the ignitability limit before being used in fumigation. The composition is manufactured by reacting a finely divided metal, selected from the group consisting of aluminium, calcium and magnesium with yellow phosphorus in an inert gas atmosphere and in the presence of a catalyst. Throughout the reaction batch and throughout the process, once reacting has commenced, a temperature is maintained within the range of 350°C to 550°C. The metal phosphide is withdrawn as a particulate free-flowing material and is packaged ready for use in phosphine generation in such free-flowing condition, essentially free of dust, essentially free of hydrolysis retarding agents and essentially free of hyrophobising substance in the form of coating or hydrophobising additives, in a gastight container.

Abstract: A micromechanical tuning fork gyroscope (14) fabricated by a dissolved silicon wafer process whereby eletrostatic bonding forms a hermotic seal between an etched glass substrate (12), metal electrodes (202) deposited thereon, and a silicon comb-drive tuning fork gyroscope (14). The dissolved silicon wafer process involves single-sided processing of a silicon substrate (1001, including the steps of etching recesses (102), diffusing an etch resistant dopant (104) into the silicon substrate (1003, and releasing various components of the silicon gyroscope (14) by etching through the diffusion layer (104) in desired locations (106). The glass substrate (12) also undergoes single-sided processing, including the steps of etching recesses, depositing a multi-metal system in the recesses (200), and selectively etching portions of the multi-metal system (202). One substrate (100) is inverted over the other (12) and aligned before anodic bonding of the two substrates is performed.

Abstract: A method and apparatus for controlling the color of an article such as a paper web includes performing a comparison between target and measured reflectance values in numerous wavelength bands spanning the visible spectrum. The comparison quantifies correspondingly numerous errors that are modified by a non-linear operation, such as squaring, and then added together. The resulting sum is minimized by individually adjusting the application of a number of colorants to the article. The number of wavelength bands is greater than the number of colorants. This avoids metameric effects which are common in conventional systems that rely on three color space coordinates such as Hunter Laboratories L, a, b: C.I.E. L*, a*, b*; chromaticity x, y, z; and tristimulus X, Y, Z. Colorant response simulators enable the effects of changes in application of colorants to be tested while the actual application of colorants to the article is unchanged.
