Title: Atomic beam generating method and apparatus
Inventor: HIRANO TAKUYA
IPC: G01N23/00
Filed: 2001-03-08
Abstract: A atomic beam generating method and apparatus for producing an atomic beam that is high in flow rate is disclosed which makes vacuum equipment simpler in construction, and is high in the rate of extraction of atoms, capable of adjusting its flow rate and applicable to many different atomic species. The atomic beam generating apparatus used produces a beam of atoms by extracting the atoms from a low temperature atomic cloud formed by laser cooling. The low temperature atomic cloud is formed by irradiating the atoms with at least two sets of laser lights in .a region of laser beam intersection in which they intersect, each of the sets of laser lights being made of a pair of laser beams which are opposite in direction of travel to each other, the laser beams intersecting in the region of laser beam intersection. In this region of laser beam intersection there is provided a laser beam shading zone in which one of the laser beams in each of the sets of laser lights that is traveling in a particular direction is obstructed to provide a shade therefor. The laser beam shading zone is so located in the region of laser beam intersection that in the laser beam shading zone a force is brought about that is effective to force atoms in the laser beam shading zone to move towards a preselected direction, thereby forming a beam thereof.

Title: Multi-phase calcium silicate hydrates, methods for their preparation, and improved paper and pigment products produced therewith
Inventor: MATHUR VIJAY K
IPC: D21H19/40
Filed: 2000-08-26
Abstract: A method for the hydrothermal preparation of calcium silicate hydrates. Mult i- phase calcium silicate hydrates, having unique physical and chemical properties, are prepared by hydrothermal reaction of specified ratios of CaO  and SiO2, normally starting from slurries of slaked lime and from fluxed calcined diatomaceous earth, each of which is at about the atmospheric boili ng point before being mixed and charged to a reactor, and pressurized. The hydrothermal reaction is carried out while maintaining the initial dilution for a preselected reaction time at a preselected reaction temperature. The calcium silicate hydrates produced have high water absorption and light scattering power, and have optical and physical properties making them highl y desirable as a filler substitute in papermaking.

Patent CA-2394317-A1 (CA)
Inventor: ARMSTRONG STEVEN M
IPC: G06Q30/00
Filed: 2000-11-27
Abstract: A presence management system is described whereby connections between watching parties and watched parties in a multiple access communications network are managed. When the presence management system receives a contact request from a watching party it determines whether the required watched party is available for contact. The system then provides information about this to the watching party who made the request. The presence management system chooses the best mode of communication (e.g. email or fax) taking into account the watched parties preferences and details about the facilities available to the watching party. If, the presence management system informs the watching party that the watched party is unavailable, the watching party is able to set up a monitor.  In determining whether the required watched party is available for contact, the presence management system uses stored information about the watched party, information about the required connection (e.g. size and type) and also rules. In addition, information about events from the multiple access network are used e.g. geographical location of watched party mobile phones.  Advantageously, information from third party applications is made available to the presence management system. For example, information about credit card transactions and calling card use. This high level information provides details about a watched party's location and activities that is accurate and up-to-date. By using this information the performance and ability of the presence management system is improved.

Title: Method and apparatus for attaching connective tissues to bone using a knotless suture anchoring device
Inventor: FOERSTER SETH A
IPC: A61F2/08
Filed: 2001-06-01
Abstract: An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone, which permit a suture attachement that lies entirely beneath the cortical bone surface. Advantageously, the suturing material between the connective tissue and the bone anchor is secured without the need for trying a knot. The suture attachment to the bone anchor involves the looping of a length of suturing material around a self-locking wedge block in the anchor, thereby avoiding an eyelet connection which requires a kot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over cnventional techniques, and the innovative procedures are significantly easier to perform than conventional techniques.
