Title: Vacuum belt media support for ink-jet printer wherein the belt is supported above a platen surface by a series of rollers to reduce belt friction drag
Inventor: WOTTON GEOFF
IPC: B41J11/06
Filed: 2000-09-28
Abstract: Print media 36 is transported through a print zone (38,Fig.1) of an ink-jet printer by a uniformly porous belt 20 supported by a platen 30. The platen has a number of cylindrical rollers 40 disposed in associated recesses 44 on the support surface 28 thereof, which protrude therefrom to provide rolling support for the belt as it is driven across the platen. The rollers ensure that the belt remains planar as it moves across the platen support surface, and also minimize the friction developed between the platen support surface and the underside 46 of the moving belt. The platen support surface includes ports 42 to provide a uniform distribution of vacuum pressure from a supply (32,Fig.1) across the belt and in turn to the media thereon. An air dam 62 may be provided to limit the application of the vacuum pressure to the underside of the belt, such that no leak occurs from the side edges of the platen. Low friction sliders (140,Fig.6) or heated protrusions (270,Fig.8) may be attached to the support surface of the platen instead of the rollers. The belt support may include a layer of low friction material (e.g. Teflon (RTM)) disposed between the belt and platen support surface to ease movement of the belt over the platen.

Title: Treatment of acne vulgaris skin condition by irradiation with light of specific wavelengths to target specific chromophores & stimulate collagen production
Inventor: CLEMENT ROBERT MARC
IPC: A61B17/00
Filed: 2000-10-18
Abstract: There is provided apparatus for the cosmetic treatment of a skin condition which comprises means for delivering illuminating radiation to a target skin zone or structure. The skin condition may be acne vulgaris or Rosacea. A method for the treatment of such a skin condition comprises directing illuminating radiation (including that of a predetermined wavelength) to a target skin zone in accordance with a predetermined delivery regime in order to effect (preferably contemporaneously) at that zone: <SL> <LI>(a) a reaction which leads to at least partial disabling or eradication of the cause of the skin condition and <LI>(b) non-ablative heating of the tissue in order to stimulate an inflammatory response to a degree sufficient to effect collagen production. </SL> The illuminating radiation may be delivered continuously or in pulse mode (eg with pulses in the range 10 žs to 100 ms, especially 50 žs to 10 ms) and its source may comprise laser diodes or light emitting diodes (LED's), with filters for the required selected wavelength, if necessary. The wavelength of the illuminating radiation is preferably in the range 400-1500 nm, especially 500-650 nm and preferably comprises a narrow wavelength band in the range 570-595 nm (yellow). The energy density is preferably in the range 0.5-5 J/cm<SP>2</SP>, with the apparatus advantageously being configured to allow variable selection of energy densities within that range but inhibit output above that range. For acne vulgaris, interaction (a) above is achieved by targeting the chromophore porphyrin in haemoglobin which aggregates at the site of inflammation. Excitation with yellow light (ca 585 nm) produces singlet oxygen photochemically which destroys the adjacent bacterium responsible for acne vulgaris (proprionibacterium). Interaction (b) above is achieved by targeting the chromophore (oxy)haemoglobin in the dermal vasculature The resulting photothermolysis effect stimulates, via inflammatory mediators, the production of fibroplasts which are responsible for the production of collagen, the skin's natural filling material, which improves skin texture and appearance.

Title: Wellhead templates
Inventor: SHEPHERD PAUL MARTYN
IPC: E21B41/08
Filed: 1999-07-01
Abstract: A drilling and production template for sub-sea wells comprises a plurality of individual limbs (1-4) each with a central hub (10-40) at one end of an arm (11-41) and a drilling receptable (12-42) on the other end of the arm. The hubs are of different diameters such that they fit within each other in a telescopic manner. They have cut-outs (27, 37, 47) which accommodate the arms of the other limbs when installed. The template may be deployed onto a pre-installed foundation with the arms stacked vertically above the other, in such manner as to pass through the moonpool of a drilling vessel. The complete assemblies are installed on a mechanical running tool attached to a drilling string. After the template is disposed on the foundation, the drilling string is rotated, causing the running tool to rotate the limbs (1-4) so that the hubs telescope into each other, providing a splayed multi-well drilling and production template.

Title: Filter with means for retarding cake formation
Inventor: CHANG SHIH-CHANG
IPC: B01D29/11
Filed: 2001-12-12
Abstract: A filter unit with inside-out flow though a cylindrical filter element 3 has a diffuser 41 inside the filter element to induce a cross-flow of raw fluid across the inside surface of the filter element to retard cake deposition, and so prolong operational time between cleaning sessions. The diffuser 41 is a body housing a flowpath with a reducing section 410, a throat section 411 and an expanding section 412. As fluid enters through inlet 61, low-pressure and high pressure areas are produced at the inlet 413 and outlet 414 respectively of the diffuser to create a cross-flow 5 in the gap D between the filter element 3 and the diffuser 41. This prevents particles settling on the inside of the filter element and allows filtrate to pass through the filter element to the outlet 62 for a longer time before clogging. The inlet 61 may have a nozzle (610, Fig 4) to increase flow velocity into the unit. In Fig 5, the cross-flow between the diffuser 110 and the filter element 13 follows a spiral path along fins 112. The diffuser may also carry brushes on the tips of the spiral fins 112 and be rotated by fluid flow to keep particles away from the filter surface.

Title: Refrigerant compressor and pressure-resistant vessel
Inventor: IKEDA KIYOHARU
IPC: H02K5/22
Filed: 2002-03-26
Abstract: In a prior-art refrigerant compressor, a three-phase integral-type sealed terminal, in which three pins connected to a three-phase power source are disposed on one metal base portion, is attached to a body portion 10d of a closed vessel 10, for supplying electric power to an electric motor 7. When a high hydrostatic pressure load is applied to the closed vessel, it is deformed into a barrel shape, and the sealed terminal pulled in the circumferential direction owing to the deformation of the closed vessel is deformed elliptically. There may arise a problem with a glass material for insulating the metal base portion from the pins. To solve the problem, three small-diameter sealed phase terminals 6 independent of one another are disposed in the body portion 10d of the closed vessel 10, for supplying electric power to the electric motor unit 7. The terminals 6 are arranged substantially in a line in the circumferential direction of the body portion 10d of the closed vessel, or in a triangular arrangement. Pipes 3,4 are attached to respective holes 10b,c with a burred portion 12.
