Patent CA-2149445-A1 (CA)
Inventor: FARUQI AZIZA BUSHRA
IPC: G06F9/54
Filed: 1995-05-16
Abstract: The interprocess communications subsystem (IPC) of the microkernel, manages the message passing operations for the communication of control information and data between tasks. Every message sent from a sending task to a destination,  receiving task must use the IPC subsystem to manage  its  transmission.  The  separation  of  transmission  control information from the data portion of the message allows the performance of the message passing process to be linked to the relative complexity of the message to be transferred between two tasks. The transmission control information of a message is parsed only once and is copied, at most, only once in its sequential path from the sending task to the IPC subsystem, and then from the IPC subsystem to the destination task. If the message cannot be transmitted,  for example because of processor resource exhaustion, a time out expiration, or insufficient port rights, then processor time is not wasted in the abortive transfer of the data portion of the message. In this manner, every message is required to interact with the IPC subsystem to bring order and predictability to interprocess communications in a busy, multitasking system, and yet the performance of the system is maximized.

Title: System for locating an end effector of a robot relative to a part
Inventor: PANYARD JAMES ROBERT
IPC: B25J17/02
Filed: 1995-06-29
Abstract: A system including a specifically-shaped probe and a complementarily-shaped hole formed in a surface of a part to be picked up ensures proper alignment between an end effector which picks up the part and the part itself.  The probe includes first, second, third and fourth mutually converging locating surfaces terminating at a rounded tip at a free end of the probe.  The probe is preferably diamond-shaped in cross-section along its entire length and the hole, consequently, is also diamond-shaped.  The hole is defined by an inner peripheral diamond-shaped surface configured to be immediately adjacent and substantially parallel to each of the locating surfaces only when the end effector is in a proper pick up position and orientation with respect to the part.  Preferably, the end effector is a gripper wherein the probe is adapted to be secured between gripping jaws of the gripper.  In the preferred embodiment, the part comprises dunnage.
Patent CA-2154846-A1 (CA)
Title: Method and apparatus for testing wells using dual coiled tubing
Inventor: GRIFFITH MICHAEL J
IPC: E21B49/08
Filed: 1995-07-27
Abstract: A new drill stem test apparatus and corresponding method includes a dual coaxial coiled tubing adapted to be disposed in the wellbore. The dual coaxial coiled tubing includes an inner coiled tubing, and an outer coiled tubing surrounding and enclosing the inner coiled tubing and forming an annular space which is located between the inner coiled tubing and the outer coiled tubing. The annular space is adapted to contain a pressurized kill fluid. A first end of the outer coiled tubing is sealed by a sealing element to a first end of the inner coiled tubing, the end of the inner coiled tubing extending beyond the sealing element and adapted to receive a formation fluid. The first ends of the inner and outer coiled tubing are disposed in a wellbore. A second end of the inner and outer coiled tubing is wound onto a coiled tubing reel and is connected to a kill fluid valve and a formation fluid valve. When the kill fluid valve opens while the formation fluid valve is closed, a pressurized kill fluid fills and pressurizes the annular space between the inner and outer coiled tubing. While the kill fluid valve is still open, the formation fluid valve is opened. A formation fluid begins to flow from the formation through the inner coiled tubing and through the formation fluid valve. If the inner coiled tubing forms a hole and begins to leak formation fluid, the pressurized kill fluid in the annular space will prevent the formation fluid in the inner coiled tubing from leaking out of the interior of the inner coiled tubing and into the annular space.

Title: Disposable toothbrush having mint flavored toothpaste composition bonded to bristles thereof
Inventor: SANDUJA MOHAN L
IPC: A61K8/00
Filed: 1994-11-10
Abstract: A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the product can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.

Title: Device for programming time fuses of projectiles
Inventor: MUENZEL KLAUS
IPC: F42C9/00
Filed: 1996-07-05
Abstract: In this more cost-effective, less elaborate method, the disintegration time is calculated from a predetermined muzzle velocity and a distance to the target and is transmitted to a receiver coil prior to firing. The receiver coil is connected via a comparator circuit (7) and a decoder (6) with a shift register (9), whose output is connected to a first comparator (6), so that the disintegration time is present on the outputs of the latter. A first counter (1), which is connected with a clock generator (2) and a programmable counter (3), is unblocked or blocked by the start-stop pulses, supplied via the receiver coil, of a muzzle velocity measuring device. The programmable counter (3) forms a clock signal from the number of the clock pulses, added in the first counter (1) during the unblocked time, and of the clock generator frequency, whose frequency is equal to the muzzle velocity and is supplied via a binary circuit (4) to a second counter (5). The output of the second counter (5) is connected with the first comparator (6), wherein a firing signal (Z) appears at the output of the first capacitor (6) when the counter reading of the second counter (5) and the reading of the shift register (9) are the same.

This second pipe section (3) is joined to the inlet opening (2.1) of the main runner (2) also in a gastight manner, At the end of the pipe sections (12) a T-shaped pipe section (13) is provided which lets the pig iron flow into one of the pig iron transport carriages.    To keep free the open cross-section of the working lining of the pipe section (3) inert gas is injected which also keeps free the ceramic plate of the slide valve (6).
Patent CA-2185002-A1 (CA)
Inventor: LESLIE SAMUEL A
IPC: H04J3/06
Filed: 1995-03-07
Abstract: A cell extender (100) for use in digital cellular telephone systems (102) comprises a control module (134), a scanning module (132), and several traffic modules (130's). The control module (134) bidirectionally repeats the donor cell site (110) control channels. Voice modules therein bidirectionally repeat selected donor traffic channels for mobiles (112). The voice module amplifies and translates the Reverse Digital Traffic Channel (RDTC) (164) (transmitted by the mobile (112)). The voice module reframes the Forward Digital Traffic Channel (166), and advances its timing such that RDTC signals transmitted by the mobile (112) and repeated by the cell extender (100) arrive at the donor (110) with the correct timing alignment. The timing advance compensates for RF path propagation delay between the donor (110) and the cell extender (100), and for any additional delay through the cell extender (100). If the voice module determines that the mobile (112) is leaving the cell extender coverage area, it sends a hand-off message returning the mobile (112) to the assigned donor traffic channel.

Abstract: A method for determining and identifying common elements, discrepancies and differences between the actual floor plans of buildings or other constructions and the floor plans for such buildings or constructions as have been approved by applicable governmental or other agencies. The method comprises first obtaining a sample orcopy of the approved floor plan for the building or construction and inputting the approved floor plan into a computer database. Next the building or construction is inspected and measured so that measurements of the actual floor plan can be entered into the computer database. The computer can them be used to create an as-built image of the building or construction floor plan after which the as-built image and the approved floor plan can be superimposed over one another to create a superimposed image. The superimposed image will visually identify common elements, discrepancies and differences between said actual floor plan of the building or construction and the approved floor plan.
