Abstract: The Multimode Interference coupler according to the invention has smoothly continuous inwardly tapered sidewalls (301) which define the width of the multimode region (W1) along the propagation axis of the device. The inward taper causes the average width of the device to be reduced in comparison to known couplers having straight sidewalls (202). Further, the invention allows the access waveguides (303, 309) to remain sufficiently spaced, while reducing the overall length of the device, to avoid lithographic gap fill-in and unwanted optical coupling between the access waveguides.

Title: Mass spectrometry with multipole ion guides
Inventor: GULCICEK EROL E
IPC: H01J49/42
Filed: 1999-05-29
Abstract: A mass spectrometer (40) is configured with individual multipole ion guides (60, 62) configured in an assembly in alignment along a common centerline (5) wherein at least a portion of each multiple ion guide (60, 62) mounted in the assembly resides in a vacuum region (72, 73) with higher background pressure. Said multiple ion guides (60, 62) configured in a higher pressure vacuum region (72, 73) are operated in mass to charge selection and ion fragmentation modes.  Individual sets of RF, +/- DC and resonant frequency waveform voltage supplies provide potentials to the rods of each multiple ion guide allowing the operation of ion transmission, ion trapping, mass to charge selection and ion fragmentation functions independently in each ion guide (60, 62). The presence of background pressure maintained sufficiently high to cause ion to neutral gas collisions along a portion of each multiple ion guide linear assembly allows the conducting of Collisional Induced Dissociation (CID) fragmentation of ions by axially accelerating ions from one multiple ion guide into an adjacent ion guide, analoguous to a triple quadruple ion function.

Abstract: The ski boot comprises an upper shell area and a lower shell area. The front and sides of the upper shell area are firmly supportive. The rear of the upper shell area is stiff, so that the back of the leg is strongly supported. In the lower shell area is the sole, which is lifted greatly at the rear by locating a high heel under the rearward region of the sole. The sole rigidly supports the foot, especially in a torsional manner. The skier's heel is lifted causing the ankle to become less bent and have greater mobility. The lifted sole functions with the upper shell area, to help the skier apply edge pressure to the ski while allowing the skier to more easily maintain a balanced position. An arch substructure is positioned under the mid-sole region to ease walking on stairs.

Title: Process for making metal flakes
Inventor: ENLOW HOWARD H
IPC: C09D7/61
Filed: 1999-10-22
Abstract: A process for making high as-pect ratio metal flakes economically and at high production rates com-prises applying a multi-layer sand-wich of vapor deposited metal and release coats in alternating layers to a rotating chilled drum or suitable carrier medium contained in a vapor deposition chamber. The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent or water soluble materials applied by suitable coating or vapor deposition sources contained in the vapor deposition chamber. The release coat materials can be a thermoplastic solvent-soluble polymer, a water soluble inorganic salt, or a high boiling point dissolvable wax-like substance. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable solvent or water to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free. The solvent or water and dissolved release material are then removed by centrifuging to produce a cake of concentrated flakes which can be air milled and let down in a preferred vehicle and further sized and homogenized for final use in inks, paints or coatings.

Abstract: A domestic gas storage water heater utilizes a plastic non pressure tank to deliver mains pressure hot water. The heater may be external or internal of the tank and has a heat out put of about 4-10 Mega joules per hour. A pressure transfer module uses the mains pressure of the incoming cold water to deliver hot water from the tank at mains pressure.
