Patent CA-2149124-A1 (CA)
Title: Optical spectrum analyzer and encoder using a modulated phase grating
Inventor: SPILLMAN WILLIAM
IPC: G02F1/09
Filed: 1993-11-16
Abstract: An apparatus and method of wavelength detection and parameter sensing uses a variable magnetic field applied to a Faraday effect thin magnetizable film to perform spectral analysis based on detected intensity distribution of diffracted light for known magnetic field strengths. The strength of the applied magnetic field can also be varied by change in a physical parameter relative to a fixed magnet in a magnetic circuit which generates a magnetic field about the grating to produce diffracted wavelengths which correspond to the parameter which influences the magnetic circuit.

Patent CA-2154464-A1 (CA)
Inventor: ALLEN BRUCE S
IPC: H04M3/56
Filed: 1994-01-31
Abstract: An improved system for connecting and processing a plurality of phone users in a teleconference on a common digital bus. The apparatus includes a plurality of digital processing units (DSPs) associated with selective phone lines and in communication with each other. Each DSP determines an activity status for each associated phone line and transmits that status to the other DSPs. The DSPs create and update respective identical "talk-lists" which reflect the active conferees whose voice data is currently being output on the phone channels. The system thus provides scaleable teleconferencing in a real-time configuration without switching between the various signals on the common bus such that each incoming caller or even a plurality of conferences has equal priority.

Patent CA-2157226-A1 (CA)
Inventor: MEUBUS CHARLES J
IPC: H04M1/66
Filed: 1995-08-30
Abstract: In methods and apparatus for controlling access via a public switched telephone network to dial-up ports identified by directory numbers, each connection request specifying the particular directory number is detected at a switch of the switched network.  On detection of a connection request specifying a particular directory number, call processing of the connection request is suspended at the switch, and a screening request is sent from the switch to a service vehicle.  The screening request comprises the particular directory number and data identifying a calling line from which the connection request was received.  The service vehicle determines whether access to the dial-up port is permitted to the calling line and returns a screening response from the service vehicle to the switch. The screening response indicates whether the connection request is to be accepted.  On receipt of the screening response, the terminating switch completes call routing to a destination determined by the screening response. The switched network may be an Advanced Intelligent Network (AIN).

Filed: 1995-09-12
Abstract: A conveyor toaster has air chambers at opposite sides and at the top of the oven for reducing surface temperatures of the out side housing panels of the oven which a worker might touch.  A wire link conveyor belt extending through the oven and carrying food products at a speed which toasts those food product during their dwell time within the oven.  The conveyor belt is tensioned by a spring bias so that a force directed against the spring bias creates a slack which enables an installation, removal, and reinstallation of the conveyor belt.  A heating element is supported at a height above the belt which may be during manufacturing to accommodate the height of a food product conveyed by the conveyor.  A loading rack at the front of the housing has two stable positions for enabling either batch loading or continuous loading.

Title: Locking device for selectively preventing access to the valve handles of a domestic water tap
Inventor: JONES STEVEN
IPC: F16K35/10
Filed: 1995-11-14
Abstract: A locking device for selectively preventing access to the valve handles of a domestic water tap. The locking device is adapted to prevent a child from playing with the hot water tap handle and potentially getting burned by the hot water emanating from the hot water tap. The locking device has a pair of handle enclosing components which are adapted to enclose the tap handles and prevent access to the latter. Each handle enclosing component has a substantially concave-shaped wall defining a substantially hollow body. Each substantially concave-shaped wall has a corresponding peripheral edge defining a lateral aperture. The handle enclosing components are linked together by a pair of connecting rods extending from the respective peripheral edges of the handle enclosing component. Both connecting rods are attached to a locking block positioned intermediate the handle enclosing components. The locking block slidably receives the connecting rods and allows the handle enclosing components to be locked in a predetermined spacing relationship relatively to one another. The user is thus adapted to initially position the handle enclosing components on each side of the tap handles and then to slide the handle enclosing components over the tap handles. Once the tap handles are enclosed inside the handle enclosing components, the user prevents the handle enclosing components from being laterally withdrawn from the tap handles by using the locking block.

Abstract: A tank connector assembly for mounting in the wall of a steel tank. A metal spudmember having an internally threaded portion and a cylindrical wall portion is welded to the tank. A sub-assembly comprised of an insert member made from a polymer material and having an internal groove therein and an expandable band member positioned in the groove. The sub-assembly is positioned inside the cylindrical wall portion of the spud member. The expandable band is in the groove of the insert member is expanded to force the insert member into tight sealing contact with the spud member. A polymer material is introduced into the interior of the steel tank and the tank is then subjected to a rotational casting movement in the presence of heat to cause the polymer material in the tank to be uniformly distributed over the internal surface of the tank. The heat applied during the rotational casting step serves to cause the inner tank of polymer material to become bonded to the insert member.

Patent CA-2172859-A1 (CA)
Inventor: BAJORINAS ANDREW P
IPC: B07C3/18
Filed: 1996-03-28
Abstract: The invention is a method and apparatus for generating a coded address list. The method is initiated by inputting an address list to a data processing device which then reads each address record on the address list.      As an address record is read, a set of rules is applied to the record to determine whether or not a corresponding bar code can be assigned. If a bar code can be assigned, then the data processing device writes the address record and its corresponding bar code to a first list. If, however, a corresponding bar code is not determined for an address record, then the unmatched address record is posted to a second list. The first list is output for printing, while the second list is saved to memory. With respect to the second list, the system operator can: manually correct an address record on the list; delete the address record; or, output the address record to a printer for non-discounted mailing. The apparatus for generating the coded address lists comprises data processing means for accepting the address list and for accepting a set of postal service rules for coding the address records on the list. The data processing means has a memory for storing the postal service rules, and coding means for coding the address records.      Additionally, the apparatus has compiler means for compiling the lists of coded and non-coded address records; and, output means for outputting the coded list for printing, and further for outputting a report.
