Title: Ammonia synthesis process and apparatus for use therein
Inventor: MOORE DEWEY OREN
IPC: C01C1/04
Filed: 2001-03-02
Abstract: A method for synthesis of ammonia includes compressing a synthesis gas containing hydrogen and nitrogen in a multi-stage (50, 56 and 57) centrifugal compressor. The synthesis gas is compressed to a pressure of from about 800 to 900 psia in the first stage (50) of the compressor, and withdrawn therefrom and subjected to cooling and dehydration by contact with liquid ammonia in a dehydrator (54). The cooled, dehydrated synthesis gas is then returned to the compressor and introduced into the second stage (56) thereof. Because of this interstage cooling and dehydration, compressor speed may be reduced and significant savings in power consumption are attained because of the favorable effect of the dehydrator (54) on the last two stages (56, 57) of the compressor. Additional power saving is realized because refrigeration requirements for the synthesis loop are reduced. Apparatus to carry out the process includes a centrifugal compressor fitted with a synthesis gas outlet (2, 4 and 6) connecting the discharge of the first stage (50) of the compressor with the synthesis gas inlet of the dehydrator (54), and a synthesis gas intermediate inlet (8) connecting the inlet of the second stage (56) of the compressor in flow communication with the synthesis gas outlet of the dehydrator (54).

Title: Switchable wavelength laser-based etched circuit board processing system
Inventor: SWENSON EDWARD
IPC: B23K26/06
Filed: 2000-12-05
Abstract: A wavelength switchable laser (10) of this invention is based on a solid-sta te laser source (12) in which a fourth harmonic UV laser beam (26) is ordinaril y used for processing, and a second harmonic "green" laser beam (28) is dumped  and wasted. However, thisinvention uses the ordinarily wasted green laser be am for processing ECB (30) conductor layers (32, 36), which enhances processing  throughout because of the higher power of thegreen energy than of the UV energy. A Pockel cell (16) effects laser beam polarizationswitching that causes either the green beam or the UV beam to be directed to the ECB forprocessing different materials. This invention requires only a single rai l laser source and is, therefore, simple, cost effective, efficient, inherentl y aligned, and has high processing throughput.

Title: Anonymity in a presence management system
Inventor: ARMSTRONG STEVEN M
IPC: H04L12/18
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.

Title: Attachment for hair clippers
Inventor: MCCAMBRIDGE JAMES
IPC: B26B19/20
Filed: 2002-07-16
Abstract: A hair trimmer or other attachment can be secured to a conventional hair clipper. The attachment has a stationary blade and a moving blade that cut hair when the moving blade reciprocates. The moving blade of the attachment is driven by a moving blade of the hair clipper, which also reciprocates. The attachment has a housing which secures the attachment to the stationary blade or other part of the hair clipper. A drive member engages the moving blade of the hair clipper when the attachment is secured to the hair clipper, and the drive member in turn drives the moving blade of the hair trimmer attachment to cut hair. The attachment can be easily detached so that the hair clipper blades can be used to cut hair in the usual manner.
Patent CA-2394046-A1 (CA)
Inventor: PORTE ALAIN
IPC: B23K26/38
Filed: 2002-07-11
Abstract: The procedure for making holes and especially micro perforations in a composite material consists of testing a sample of the material, then perforating the material using a laser beam at the appropriate temperature using an automatic programme to control the movement of the laser. <??>The procedure for making holes and especially micro perforations in a composite material of mineral or organic fibres in a resin matrix consists of initially testing a sample of the material, using a laser beam directed at right angles to its surface, confining the temperature within the material to a range greater than the melting point of the resin matrix but lower than that causing the physical properties of the fibres to alter. The material itself is then perforated with a laser beam at the appropriate temperature, using an automatic programme to control the laser beam parameters and its movement relative to the material (8). The laser beam generator, comprising a head (10) and a laser emitter (12) connected by an optical fibre (11), has one unit (16) to control the power and focus of the beam and another (15) to change the beam's position, forming perforations of a few square millimeters. An aspiration unit (18) under the e.g. metal grille supporting table (9) removes gases and material residues.

Title: Improved process for filter aid production in alumina refineries
Inventor: WILSON DARREL JAMES
IPC: C01F7/47
Filed: 2001-07-20
Abstract: An improved process for the production of tricalcium aluminate (TCA) filter aid for use in an alumina refinery is described. Quicklime is slaked in a slaker tin using a suitable slaking solution to form a slaked lime slurry (10). A suitable surface-active agent is added to the slaking solution prior to slaking of the lime. Alternatively, the surface-active agents can be added to the slaked lime either during slaking or after slaking. The slaked lime slurry is then transferred to a stirred storage/transfer tank (12) before it is pumped to a lime aging tank (14). A concentrated Bayer liquor and steam are added to the tank (14) to provide a caustic aluminate solution that reacts with the slaked lime. Sufficient residence time is allowed in the lime aging tank (14) for the initial product of the reaction to "age" before use, forming relatively pure particles of the thermodynamically stable TCA. The addition of a suitable surface-active agent or agents at the appropriate concentration will significantly improve TCA formation in the lime aging facility. These improvements include a narrower and more symmetric sized distribution, and a more crystalline structure, leading to substantially improved filtration characteristics.
