Patent CA-2227389-C (CA)
Inventor: VELTRI MICHAEL
IPC: G01L19/00
Filed: 1998-01-20
Granted: 2001-12-18
Abstract: A dual  seal coupling fitting enables quick measurement of pressure.  The fitting includes primary and secondary valves and has one end shaped like a male portion of a quick coupler and another end screwable into a threaded bore defined in a pressure bearing housing.  The fitting defines first and second cylindrical sections in communication with each other.   The primary valve situates in the first section,  the secondary valve in the second section.   The primary valve includes a valve stem with a poppet head.  A first mechanism compresses the poppet head against an outer valve seat to close the primary valve thereby preventing leakage of pressure.   The secondary  valve  features  a  cylindrical  seat  piece  and  a retainer.   The piece secures within the second section and defines through itself an inner bore.  The piece at one end forms an inner valve seat and at an opposite end situates adjacent the first mechanism.  The retainer has at one end a post approximate a terminal end of the valve stem within the inner bore.   The retainer also has a check valve retained within an annular recess defined about a base of the post.  A second mechanism compresses the check valve against the inner valve  seat  to  close  the  secondary  valve  thereby  further preventing leakage of pressure.  Mating a female portion of a quick  coupler  to  the male portion opens  the primary and secondary valves and enables quick measurement of the pressure via a gage attached to the other end of the female portion.

Abstract: A windshield wiper washer fluid system designed to visually notify the operator of the vehicle that the windshield wiper washer fluid is getting low and should be refilled. The system includes a tank having a passenger side hose and a driver's side hose each connected thereto such that the passenger side hose only sprays washer fluid on the passenger's side of the windshield and the driver's side hose only sprays washer fluid on the driver's side of the windshield. The tank and hoses are designed such that the passenger's side hose will run out of fluid before the driver's side hose and washer fluid will only spray on the driver's side indicating that the system needs to have washer fluid added while allowing the driver to continue to clean the driver's side of the windshield.

Abstract: A jaw blade contact for a watthour meter socket adapter includes a terminal with a blade end and an opposed jaw contact end. A spring clip is fixedly mounted on the terminal and has a jaw contact end opposed from the jaw contact end of the terminal for receiving a blade terminal of a meter there-between. Angled arms carried on the spring clip releasibly engage the base of the socket adapter housing to mount the jaw blade contact on the housing in a snap-on connection. In another embodiment, a spring clip engages apertures in a jaw contact formed of two folded over portions to mount the jaw contact in the housing. The housing has a mounting flange with a frangible portion conformable to different sized socket cover openings. An arcuate surge ground conductor is mounted on the housing sidewall by an integral bendable member which is movable from an in-line position to a mounting position extendable through an aperture in the housing. One or more jaws of the jaw contact include at least first and second separately movable legs, each having a contact edge engageable with a blade terminal. The contact edges of the at least two legs are spaced apart along the length of the jaw to provide a stepped blade terminal insertion force.

Abstract: A method and apparatus are provided for communicating audio information over a computer network (214). A standard telephone (202) connected to PSTN (210) can communicate with any other PSTN-connected telephone (204), where a computer network, such as the Internet (214), is the transmission facility instead of conventional telepho ne transmission facilities. The caller dials the number of an access port (206) for the computer network and transmits the number of the called party when connected to the port. The port receives the number of the called party and establishes a two-way, full-duplex communication lin k via the computer network (214) to a corresponding remote access port or specialized computer system (216) in the vicinity of the call ed party (204). The port at the receiving end is connected to the local PSTN in the region of the called party, and uses the local PSTN to connect the call to the called party.
Patent CA-2240286-C (CA)
Title: Overpartitioning system and method for increasing checkpoints in component-based parallel applications
Inventor: LORDI ROBERT
IPC: G06F9/50
Filed: 1996-12-11
Granted: 2002-03-12
Abstract: Two methods for partitioning the work to be done by a computer program into smaller pieces so that checkpoints may be done more frequently. Initially, a parallel task starts with one or more input data sets having q initial partitions, divides the input data sets into p partitions by some combination of partitioning elements (i.e., partitioners/gatherers), runs an instance of a component program on each of the p partitions of the data, and produces one or more sets of output files, with each set being considered a partitioned data set. The invention is applied to such a task to create a new, "overpartitioned" task as follows:  (1) the partitioner is replaced with an "overpartitioner" which divides its q inputs into n* p partitions, for some integer factor n; (2) the component program is run in a series of n execution phases, with p instances of the component program bein run at any time. In each phase, each instance of the component program will read one overpartition of the input data and produce one partition of output data; (3) at the end of each of the n execution phases, the system is quiescent and may be checkpointed. A first embodiment explicitly overpartitions input data by using known partitioner programs, communication channels, and gatherer programs to produce overpartitioned intermediate files. The second embodiment dynamically overpartitions input data by arranging for the component programs to consecutively read contiguous subsets of the original input data.

Abstract: An stud mounting clip has a first bracket component and a second bracket component. The second bracket component is used to support outer wall components or panels and is fixed with respect to the position thereof. The second bracket component is allowed to move relative to a stud of the frame of the building by virtue of a first bracket component which securely engages the second bracket component such that the second bracket component may move with respect to the first bracket component. The first bracket component has an engaging component which engages the second bracket component, and a securing component which secures the second bracket component adjacent to a stud. In a preferred embodiment, the second bracket component is configured with an elongated slot in which a slightly shorter elongated engaging component on the first bracket component is received. The slot allows travel in the vertical direction thus allowing the frame and foundation of the building to settle as well as thermally differentially expand relative to the outer walls of the structure.

Abstract: An electrolytic restoration of concrete includes an anode positioned at a surface of the concrete to be restored and the communication of a current from the anode to the reinforcing bars in the concrete as a cathode. The anode is in the presence of or carries an electrolyte so that sufficient current is provided temporarily over a sufficient period of time so that ions from the concrete are carried through the concrete and expelled into the electrolyte for extraction. The anode is provided by layer of conductive material which is particulate or fibrous so that it is an amorphous layer which can therefore follow the surface of the concrete. In a horizontal arrangement, the layer can be applied directly onto a felt mat for carrying electrolyte.  In a vertical orientation an initial layer of chopped cellulose is wetted and applied onto the vertical surface followed by the same layer carrying carbon powder so that the layer is conductive and forms the anode when connected to metal connector plates buried in the anode layer.
