Patent CA-2299706-C (CA)
Title: Siphon assembly with one way priming valve
Inventor: MALECKI STEVEN JOSEPH
IPC: F04F10/02
Filed: 2000-02-29
Granted: 2007-12-11
Abstract: An improved priming assembly which maybe used for siphoning, includes a siphon tube comprising an inlet end and a discharge end. The discharge end may be connected to a discharge hose that leads to a discharge area. A one-way valve is inserted within the tube adjacent to the inlet end of the tube. The valve comprises a flexible rubber sheath a portion of which is sealed to the inner surface of the tube and which extends toward the discharge end. The sheath is movable from an open position to a closed position. When fluid is caused to flow from the inlet end to the discharge end, the sheath moves to its open position allowing fluid flow. When fluid is caused to flow from the discharge end toward the inlet end, the sheath collapses to the closed position such that it prevents flow of fluid toward the inlet end. Priming of the siphon is created when the sheath collapses into its closed position, under the weight of the fluid as the rigid siphon tube is thrust upwardly. The sheath moves to the open position as the tube moves down within the fluid to be discharged, allowing fluid flow through the valve toward the discharge end, and to accumulate within the tube.

Title: Optical waveguide component
Inventor: HOEKSTRA TSJERK HANS
IPC: G02B6/12
Filed: 1999-06-09
Granted: 2006-10-17
Abstract: The invention pertains to an optical waveguide component comprising a substrate, a core-matching refractive index lower cladding layer, a core layer, a core-matching refractive index upper cladding layer, a low refractive index upper cladding, wherein the core-matching refractive index lower cladding layer is deposited directly onto the substrate and has a thickness sufficient to avoid substantial capture and/or absorption by the substrate of a guided mode in the core layer, whereas slab modes, quasi-guided modes and/scattered light leak to the substrate. The components according to the invention allow high switching speeds and high confinement of a guided mode on the one hand and, on the other hand, absorption by the substrate of stray-light and radiation modes, which, in turn, leads to improved optical devices, such as optical switches with improved isolation.

Abstract: An apparatus and method of hydroforming provides an angled tubular part from a tubular blank. The blank at the angled portion has a concave portion and a convex portion. High pressure fluid expands the blank into conformity with a die cavity. Force is applied to at least one end of the blank so as to create longitudinal flow of metal material to maintain a wall thickness of the blank. A greater amount of force is applied to a portion of the blank which is longitudinally aligned with the convex portion in comparison with the amount of force applied to the blank which is longitudinally aligned with the concave portion so as to create a greater amount of flow of material so as to inhibit wrinkle formation.

Abstract: Ionization chamber, especially for an ion mobility spectrometer, with a non-radioactive electron source. The chamber consists of two compartments, of which one is evacuated and contains an electron source, and the other represents the reaction chamber of the IMS. In the evacuated compartment, X--ray quanta are produced in an anode by electron bombardment and these X-ray quanta can penetrate a partition between the two compartments. The partition between the two compartments is impermeable to electrons from the source and to gas molecules. In one or several conversion layers within the reaction compartment, X-ray quanta are converted to quanta of a lower energy and/or photoelectrons that can ionize the air constituents at a high level of efficiency.

Abstract: A power spectrum measurement system and a method monitor a power spectrum of N- channels in an M-channel wavelength division multiplexed optical communication network, where N is less than or equal to M. An add-drop node in the network drops a channel and adds a channel for transmitting data on the network. The added channel has the same wavelength as the dropped channel. The power of the added channel is controlled to minimize crosstalk. The power spectrum measurement system includes a detection circuit and a processing circuit. The detection circuit is an inexpensive, scalable circuit for detecting the power of each channel. The processing circuit is connected to the detection circuit and calculates the power of each channel based upon the power detected by the detection circuit. The processing circuit also calculates power of the added channel for minimizing crosstalk. The calculated power of the added channel is a function of the powers measured for the N channels, including but not limited to the average power of the N-channels or the powers of the channels adjacent the added channel. The calculated power is transmitted to the node adding the channel for controlling the power of the added channel.
