Patent CA-2240992-A1 (CA)
Inventor: GILLASPIE DAVID D
IPC: F24H9/20
Filed: 1995-12-22
Abstract: A very compact tankless heater delivers heat in proportion to demand. A flow responsive valve energizing an electrical control system is purely flow responsive, even to minute flow, and consumes no power when dormant. An uncomplicated electronic control system is connected to power by the flow switch, and is substantially deenergized when dormant. Most electronic components of the control system are mounted on the flat front wall of the pressure vessel. Thus, overall dimensions are minimized, cool water serves as a heat sink, and heat generated by electronic controls is captured for heating purposes. In particular, triacs controlling the heating elements are cooled, thus prolonging their life. A preferred embodiment of the novel heater has a maximum electrical consumption of 22 kilowatts, with equivalent heat output, and has overall external dimensions of 24 in height, 5.5 inches in width, and 4 inches in depth (61 cm in height, 14 cm in width, and 10 cm in depth). An outlet pipe fitting extending above adds approximately 2 inches (5 cm) to the overall height, enabling the water heater to be installed in a typical building interior wall of partition.

Title: Method and apparatus for preventing adhesion of multi-part release liners
Inventor: KING THOMAS M
IPC: E04D5/12
Filed: 1998-08-25
Abstract: A method and apparatus for producing a self-adhering product with a multi-part release liner system that will not result in unwanted adhesion at the edges is disclosed. The self-adhering product may be a roofing sheet, or waterproofing membrane. The multi-part release liner system includes a strip of material placed on the adhesive surface below and between each abutting edge of the release liner. The material allows each section of the release liner to be removed without the edges of the liner adhering to the underlying sheet. The release liner may also be a single piece liner, with at least one strip of perforations that allows the liner to be removed in individual sections. In this application, the material not only prevents edge adhesion, but also prevents adhesive from the substrate flowing through the perforation holes. The invention may also be applied to release liner systems that combine multi-part release liners and perforated release liners.  The method and apparatus of the invention are applicable to any self-adhesive product that requires a release liner.

Title: Facsimile machine
Inventor: SHIBATA TETSUYA
IPC: H04N1/32
Filed: 1998-08-25
Abstract: A conventional facsimile machine re-dials by using another telephone line after an elapse of a predetermined period of time since when a communication error after a line connection has occurred, so that it takes a predetermined period of time to re-dial by using the other telephone line, and hence a receiving end may receive data transmitted from another facsimile machine during this period.  In order to prevent that, a facsimile machine of the present invention comprises: a plurality of line connecting means, each of which has a telephone line for transmitting/receiving data; a line selecting section for selecting a telephone line to be used when a plurality of telephone lines are connected; and an auto-dial sending section for changing over the telephone line currently selected by the line selecting section to another telephone line so as to make a call immediately, when the receiving end is busy.

Title: Apparatus and methods for surface contour measurement
Inventor: MERMELSTEIN MICHAEL S
IPC: G01B11/24
Filed: 1997-02-03
Abstract: Apparatus and methods of measuring position information, typically the depth coordinate, of a point on the surface of an object. In one embodiment, the apparatus includes two sources of radiation (P1, P2) positioned to illuminate the point (Pa) on the surface of the object (10) with radiation from each of the sources. The radiation from each of the sources is coherent with respect to the radiation from the other source. A control system (32) changes the phase of the radiation from at least one of the sources relative to the phase of the radiation from the other source as measured at the point on the surface of the object. A detector (22) is positioned to receive radiation scattered by the point and a processor (28), in communication with the detector, calculates position information in response to the change in phase of the radiation from the source and the received radiation scattered by the point on the surface of the object.

Patent CA-2251398-A1 (CA)
Inventor: VULOVIC FREDERIC
IPC: B01F23/10
Filed: 1998-11-06
Abstract: The universal mixer device for mixing two gaseous fluids comprises an enclosure defining coaxial chambers, ducts opening out respectively into each of the chambers to feed them with two gases at medium pressure, and sonic nozzles each comprising a hollow converging-diverging body of revolution serving as seats for respective cone-shaped valve members. The valve member of one of the nozzles has an axial bore and defines the chambers at least in part. The other nozzle is disposed inside the axial bore. The hollow converging-diverging bodies of revolution occupy positions that are determined relative to the enclosure, and the valve members are mechanically linked to each other and are associated with a single actuator. The gases that have passed through the coaxial and geometrically similar nozzles flow into a common downstream chamber in which the gases mix with a predetermined mixing ratio determined by the dimensions of the nozzles.

Patent CA-2252351-A1 (CA)
Title: Variable air volume control system
Inventor: BUJAK WALTER E JR
IPC: F24F11/00
Filed: 1998-11-03
Abstract: A system controls the pressure at which conditioned is to be provided to one or more zones to be heated or cooled by the conditioned air. The system actively computes a setpoint for the pressure with a location in a duct system upstream of where any of the conditioned air is to be provided to the zones. The setpoint is computed as a function of the positional statuses of dampers within the duct system that regulate the flow of the conditioned air to the respective zones. The actively computed setpoint is compared with a sensed pressure in the duct system in order to determine whether the pressure in the duct system needs to be changed.
Patent CA-2253115-A1 (CA)
Title: Diaphragm pressure balancing valve
Inventor: BREDA SILVANO
IPC: F16K17/34
Filed: 1998-11-09
Abstract: This valve uses a rotatable balancing chamber to control the waterflow into the balancing chamber. A pair of exit ports on the rotatable balancing chamber are in communication with the balancing chambers on either side of a diaphragm equipped shuttle to control the outlet mixture of hot and cold water. The diaphragm equipped shuttle responds to changes in pressure in the respective balance chambers to throttle the water through the valve in response to changes in inlet pressures. The pressure balancing chambers are isolated from the water supplies feeding the valve when the valve is in the "off" position, and the pressure balancing chambers are pre-pressurized before any water is permitted to exit from the valve.

Title: Catio3 interfacial template structure on superconductor
Inventor: MCKEE RODNEY ALLEN
IPC: H01L21/28
Filed: 1997-07-31
Abstract: A structure including a film of a desired perovskite which overlies and is fully commensurate with the material surface of a semiconductor-based substrate and an associated process for constructing the structure involves the build up of an interfacial template film of perovskite between the material surface and the desired perovskite film. The orientation of the perovskite of the template is rotated 45° with the respect to the orientation of the underlying material surface and thereby effects a transition in the lattice structure from the foc (of the semiconductor-based material) to the simple cubic lattice structure of perovskite while the fully commensurate periodicity between the perovskite template film and the underlying material surface is maintained. The film-growth techniques of the invention can be used to fabricate solid state electrical components wherein a perovskite film (84) is built up upon a semiconductor based material (72) and the perovskite film is adapted to exhibit ferroelectric, piezoelectric, pyroelectric, electro-optic or large dielectric properties during use of the component. This process can be used to form FFETs with semiconducting substrate (72), a transistor (70), a source and drain (78, 80), gate electrode (82) and a gate dielectric (83). The perovskite (84) is part of the gate electrode.
