Inventor: GENETTI RALPH ALBERT
IPC: C07C209/38
Filed: 1999-05-14
Abstract: A process for preparing an optionally substituted 4-aminodiphenylamine comprising reacting an optionally substituted aniline and an optionally substituted nitrobenzene in the presence of water and a base while controlling the water content so as to ensure a molar ratio of water to the base charged of not less than about 4:1 at the start of the coupling reaction and not less than about 0.6:1 at the end of the coupling reaction to produce 4-nitrodiphenylamine and/or 4-nitrosodiphenylamine and/or salts thereof. The coupling reaction is followed by a hydrogenation reaction where the coupling reaction product is hydrogenated in the presence of a hydrogenation catalyst and added water so as to ensure a molar ratio of total water to base of at least about 4:1 at the end of hydrogenation. Aqueous and organic phases are obtained and the optionally substituted 4-aminodiphenylamine recovered from the organic phase.

Title: Geothermal energy means and procedure
Inventor: HARDIN JAMES R
IPC: F24J3/08
Filed: 1997-07-23
Abstract: A geothermal energy installation and system (10), in which the field of potable water (12) is utilized by a secondary conduit system (32) to route potable water (12) from an inlet (18) in the user's line (16) coming from the potable water field (12) but upstream of the user's meter (24), through the heat exchanger equipment (30) of a user, and back to the field (12) at a point upstream of the final treatment processing stage of the field. Thus, the thermal energy of the water of the field (12) is utilized without adding the cost of the volume of potable water used (27) by the user, and is re-processed if somehow contaminated in the secondary conduit systems (32); and although the secondary conduit system (32) delivers water back to the field (14) at a changed temperature, depending upon the heat exchanger (30) effect, the relatively large volume of water of the potable water field (12) assures that the returned water does not even substantially alter the temperature of the potable water field (12).

Inventor: MARRS ALAN DOUGLAS
IPC: C30B25/16
Filed: 1999-09-13
Abstract: Layer processing to grow a layer structure upon a substrate surface comprise s supplying a vapour mixture stream to the substrate (28) to deposit constituents, monitoring growth with an ellipsometer (12) and using its outp ut in real-time growth control of successive pseudo-layers. A Bayesian algorith m is used to predict a probability density function for pseudo-layer growth parameters from initial surface composition, growth conditions and associate d growth probabilities therewith, the function comprising discrete samples. Weights are assigned to the samples representing occurrence likelihoods base d on most recent sensor output. A subset of the samples is chosen with selecti on likelihood weighted in favour of samples with greater weights. The subset provides a subsequent predicted probability density function and associated pseudo-layer growth parameters for growth control, and becomes a predicted probability density function for a further iteration of pseudo-layer growth.

Abstract: The invention relates to a method for outputting data from a computer system (1) to an outputting device (7). According to said method, a master document (25) with a variable data area (27, 28, 29) and a static data area (12, 26) is generated. The variable data area (27, 28, 29) is marked and variable data (11) are placed in said variable data area (27, 28, 29). This produces a serial data flow (31) with individual documents (32, 34).  In said serial data flow, the variable data and the static data are permanently linked according to individual documents. The variable data (11, 30) are then separated from the static data (12, 33) from this serial data flow (31), using the marking. The variable data (11, 30) from the first individual document (32) are transmitted to the outputting device (7) separately from the static data (12, 33) and stored there. The static data (12, 33) of the succeeding individual documents are not transmitted to the outputting device (7). In the outputting device (7), the variable data (11, 30) are then re-linked with the stored static data (12, 33) according to the individual documents.

Title: Method and apparatus for soft handoff communications in a communication system operating according to multiple communication standards
Inventor: JALLOUL LOUAY
IPC: H04W36/18
Filed: 2001-03-30
Abstract: A soft handoff operation is provided for a first signal transmitted according to a first communication standard (IS-95B) and a second signal transmitted according to a second communication standard (IS-95C). A mobile station (MS) (204) receives the first signal, detects a pilot signal, measures pilot signal strength, and transmits a pilot strength measurement message.      When the MS fails to receive a handoff direction message after transmitting the pilot strength message, the MS searches for a detecting presence of a broadcast control channel (BCCH) associated with a type IS-95C cell site (202) and measures a carrier-to-interference ratio of the BCCH. The MS compares the carrier-to-interference ratio to a threshold, and when the ratio is above the threshold, initiates a second communication according to the IS-95C standard, thus initiating a soft handoff operation and allowing cell sites (202, 203) to transmit information according to the IS-95C and IS-95B standards, respectively.

Filed: 2000-05-26
Abstract: A dash reinforcement (10) for a mobile vehicle with a passenger cab (101) such as a sport utility vehicle, or medium or heavy-duty truck. The dash reinforcement (10) may be a stamped sheet metal panel that strengthens the dash structure of the cab and provides for mounting of vehicle components. The dash reinforcement (10) may be symmetrical about the centerline (108) of the vehicle and this symmetry allows the panel to accommodate both left-hand drive and right-hand drive vehicle configurations. The dash reinforcement (10) also includes 'Y' shaped passages for a driver control module (20) and for accessory equipment such as heating, ventilation, and air conditioning (HVAC) modules. The unique shape of these passages or openings adds strength to the overall dash structure and hence the cab. The dash reinforcement (10) may be engaged to a dash panel (70) to form a dash assembly (50). The dash panels may be manufactured by the same metal stamping dies moved to account for left-hand versus right-hand drive and conventional versus cab-over-engine or low front engine configuration.
