Title: Gear profile for orbital gear transmissions, and orbital gear transmission and winches utilising orbital gear transmissions
Inventor: WILLMOT ERIC PAUL
IPC: B66D1/04
Filed: 1997-07-15
Abstract: A gear profile for orbital gear transmission is disclosed in which an outer gear (10) and an inner gear (30) are included.     At least one of the gears is constrained for orbital motion to impart rotary motion to the other of the gears. The profile of teeth (34) of inner gear (30) is sinusoidal at least in the vicinity of pitch circle (36) of the gear (30) and the pitch circle (36) coincides with the point of inflection (52) of the sinusoidal profile of the teeth (34).     The outer gear (10) has a pitch circle (25) and the point of inflection (19) of the inner gear (30) rolls across the point of the profile of teeth {14) of the outer gear (10) where the pitch circle (25) intersects the profile of the teeth (14). Orbital transmission systems are disclosed in which one or the other of the inner gear (10) or outer gear (30) is mounted on an eccentric (63) which is driven by an input shaft (64). An orbit control plate (67) or regressive gear (110) restrains one of the gears (10 or 30) for orbital motion and the plate (67), or regressive gear (110), has a braking member (80) for fixing the plate (67), or regressive gear (110), stationary. In order to place the transmission into neutral, the brake (80) can be released so that the orbit controle plate (67) is able to rotate rather than to constrain the outer gear (10) or inner gear (30) for orbital motion.

IPC: G02B5/18
Filed: 1999-06-23
Abstract: The present invention relates to a fiber grating formed on an optical component for processing optical signals and a method of forming the grating. After the sheath (2) of an optical fiber ribbon (3) is partially removed, the surface of the bare optical fiber (1) at an area where the sheath (2) is removed is covered by a resin film (7) having a thinness at which ultraviolet light permeability not hindering formation of gratings. Thereafter, by irradiating ultraviolet light (ultraviolet coherent light) via a phase mask (9), a grating where the refractive index of the core (4) of the bare optical fiber 81) cyclically changes in the beam axis is formed. The resin film (7) is made of, for example, an organic material having heat resistance, which is not dissolved by ultraviolet ray irradiation, such as polyimide resin, polyamideimide resin, etc. The thickness of the resin film (7) is 10 µ m or less to ensure that ultraviolet light sufficiently permeates and the convergence of interference light is not lowered.

Title: Apparatus for supplying radioactive gas to a delivery device
Inventor: BATES BRIAN L
IPC: A61F2/958
Filed: 1998-12-01
Abstract: Disclosed is a catheter apparatus filled with a radiation carrier material such as an inert radioactive gas for the treatment of restenosis after angioplasty, and malignancies. The inflated catheter includes a single unit or alternatively, a plurality of discrete chambers for transporting the radioactive carrier material and through which, blood may continue to flow during treatment with the prescribed radiation. When the radioactive carrier is a gas such as Xenon 133, an injection apparatus (1400) may be used that permits use of a standard radioactive gas source vial (1401) that may be loaded into the radioactive source vial enclosure or chamber (1403). The means for enclosing the vial (1404) may also serve as an urging mechanism (1442) to urge the source vial (1401) toward one or more piercing cannulae (1406, 1454) which permit delivery of the radioactive gas to the catheter. In one series of embodiments, the radioactive gas is withdrawn through a selector means (1409) such as a multiple position valve into a gas-tight variable volume chamber (1411) such as a syringe which then is deployed to deliver the gas into the catheter. Following treatment, the gas is withdrawn into the syringe and returned to the source vial (1401). In another series of embodiments a syringe filled with a liquid is used to displace the gas either directly into the delivery catheter (1422), or into a second syringe which injects the gas to the delivery catheter (1422).

Inventor: CARDARELLI FRANCOIS
IPC: C04B35/622
Filed: 2000-12-28
Abstract: The present invention describes a method for producing bulk, particulate high crush strength, and inert ceramic materials with a quasi-spherical shape prepared from raw oxide residues. These oxide residues are produced from the regeneration of spent acids based on a pyro-hydrolysis process, and/or as by-products from mineral processing and ore beneficiation operations. The final solid granules are obtained from the thermal treatment of previous raw oxide residues by several ceramics processing routes. These routes use common granulation processes well known in the ceramics industry.  The final solid particles which exhibit both a high crushing strength, a low density, an elevated corrosion resistance in both brines, and acidic media, high indicia of sphericity and roundness are extremely suitable to be used in numerous industrial applications requiring inert and crush resistant quasi-spherical granules. Among these applications, owing to their excellent mechanical, thermal properties, and chemical inertness the granules can be used competitively as propping agent in the oil well production, and in a lesser extend due to their refractory behaviour as foundry sands in the metallurgical industry.

Patent CA-2335001-A1 (CA)
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder.  A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Abstract: An item of footwear has an opening (4) for insertion of a wearer's foot and a pair of rigid fastening elements (10) and (11) for drawing together opposite  sides of the opening. The first element (10) has a screw thread (14) to receive a bead (15), and the free end of the second element (11) is bent orthogonally and formed into a U-shapedhook (16). When the wearer has placed  his/her foot into the boot the element (10) is placed over the mouth of the hook (16). By applying gentle finger pressure the bead (15) is caused to rid e over the shank of the second element (11) so that the hook (16) embraces the  first element (10) and engages behind the bead (15). The tension in the fastening can be adjusted by screwing the bead (15) along the thread (14). T he fastening is easy to engage and disengage when the wearer's fingers are cold  or when wearing heavy gloves, yet the fastening is secure enough to be used with snowboarding or ski boots.

Abstract: In an IP-based Code Division Multiple Access (CDMA) 2000 packet-data cellular telecommunications network, a method and system for handing over a dormant Mobile Node (MN) to a target packet zone. According to the invention, first the dormant MN sends an origination request message to the target Base Station Controller and Packet Control Function (BSC/PCF), which further sends a registration request comprising an indication that the MN is dormant to a Packet Data Service Node (PDSN). The PDSN replies to the BSC/PCF with a registration reply message for requesting the establishment of a traffic channel for the MN, and for indicating that it has data packets ready to be sent to the MN, such as for example Link Control Protocol (LCP) data packets for use in the negotiation of a new Point-to-Point Protocol (PPP) connection. The registration reply message comprises an indication such as for example a Data ready to Sent (DRS) parameter set to 1. The BSC/PCF establishes the traffic channel and forwards the data packets to the MN. Following the receipt of the registration reply in the BSC/PCF, the paging of the MN is avoided.
