Title: Compatible licensed and unlicensed band portable handset unit for tdma wireless communication system
Inventor: CHANG LI FUNG
IPC: H04Q7/32
Filed: 1995-12-15
Abstract: In a TDM/TDMA portable radio communications system (5), a portable handset (201) is compatible for operation in FDD mode and TDD mode. In the FDD mode, different frequencies are used to separate a downlink transmission to a portable (201) from a port (204) from an uplink transmission from a port (204) to a portable (201). In the TDD mode, uplink and downlink transmissions are separated in different time-slots, but at the same frequency. The handset (201) includes common transmit and receive circuitry (300) that operates at fixed IF frequencies separated by the fixed FDD frequency difference between corresponding uplink and downlink signals. In the FDD mode, afrequency synthesizer (301), which is used to tune to transmit and receive at different frequencies from different ports, is not switched in frequency between transmitting and receiving a burst to and from a single port. In the TDD mode, the synthesizer (301) is switched in frequency between transmitting uplink and receiving downlink even though uplink and downlink signals are at the same frequency.

Patent CA-2214652-A1 (CA)
Inventor: SCHULTE ROBERT L
IPC: G01T3/08
Filed: 1996-03-07
Abstract: A directional thermal neutron detector includes an array of individual thermal neutron detector modules (20) each of which comprises front and back planar silicon detectors (22, 24) having a gadolinium foil (26) sandwiched therebetween. The array comprises a plurality of individual detector modules (20) which are angularly displaced with respect to each other. The direction of the thermal neutron source is determined by comparing the magnitudes of the output signals from the plurality of angularly displaced detector modules (20). Each module (20) is segmented into four quadrants. The thickness of the gadolinium foil (26) in each module (20) is at least 15 microns thick, to improve the front-to-back silicon detector counting ratio to ascertain the side (front or back) from which thermal neutrons are arriving at the detector. Gamma rays are discriminated against by using coincidence signal processing within the elements of the detector sandwich to reduce the gamma ray contribution to the total signal.

Title: Telephone/transaction entry device and system for entering transaction data into databases
Inventor: MARTINO ROCCO L
IPC: G06F17/30
Filed: 1996-05-16
Abstract: A data transaction processing system (figure 1) in which transaction data is entered from a transaction entry device (12) by the user in response to prompts in a template (figure 2) which is tailored to each user application. The template (figure 2) and entered data are accumulated into data transactions which are immediately transmitted upon completion to one or more database servers (28) and their associated databases (30) for processing and storage. The data transactions are not locally stored for processing, and no conventional operating system is necessary. No local processing needs to be provided, and the only local storage is a flash PROM (95) which stored the control firmware, a flash memory (96) which stores the data streams making up the forms and menus, and a small RAM (97) which operates as an input/output transaction buffer for storing the data streams of the template (figure 2) and the user replies to the prompts during assembly of a data transaction.

Title: Method and apparatus for breaking hydrocarbon emulsions
Inventor: HADLEY HAROLD W
IPC: C10G33/06
Filed: 1996-05-20
Abstract: A method for breaking an emulsion comprising oil and water into oil and water phases comprising treating the emulsion with a chemical demulsifier and passing the mixture through a hollow chamber having a uniform cross section and subjecting the mixture to acoustic energy in the frequency range of about 0.5 to 10.0 kHz, preferably 1.25 kHz, to enhance breaking the emulsion into a water phase and oil phase. The oil phase is then separated from the water phase by gravity separation and recovered. The sonic energy is generated by a transducer attached to the mid-section of the upper or lower outer surface of the hollow chamber. For emulsions containing light oil having an API gravity greater than 20 and water, the emulsion can be broken by the use of acoustic energy in the frequency range of about 0.5 to 10.0 kHz without the addition of chemical demulsifiers.

Title: Variable period amplitude grating mask and method for use
Inventor: COOK THOMAS A
IPC: G02B6/34
Filed: 1997-07-29
Abstract: A variable period amplitude grating mask for use in making a long period Bragg grating is realized by a helically coiled spring. Stretching or compressing the spring changes the periodicity of the mask. A photosensitive optical waveguide, planar or fiber, is positioned within the spring coils along the major axis of the spring. Actinic radiation is incident on the masked waveguide, and induces an index perturbation in the waveguide having the periodicity of the mask. Different spring coil sizes and/or orientation of the waveguide with respect to the mask provide linear and nonlinear (chirped) grating periods. A device and method are described.

Filed: 1997-11-03
Abstract: In an electric power generation system (2), there is a cross-flow stack (4) of fuel cells (6) each having an anode, electrolyte, and a cathode. Associated with the anodes are anode passages which in each cell are divided into a first group formed by anode passages (28a) and a second group formed by anode passages (28b). Fuel gas, for example methane from a supply (26) is fed via path (34) to an inlet manifold (38a) to the anode passages (28a), and a portion of anode exhaust gas from the anode passages (28a) is fed via an exhaust outlet manifold (40a) and lines (42, 46) to an inlet manifold (38b) feeding the anode passages (28b). A reforming reaction takes place in the anode passages (28a and 28b). The other part of the anode exhaust gas from the exhaust manifold (40a) is fed via lines (42 and 44) to the line (34) to mix with the fuel gas. Atmospheric air provides the oxidising gas supplied on line (18) to the cathodes. That oxidising gas is heated in a heating arrangement (21) in which anode exhaust gas from the anode passages (28b), and supplied on line (50), is burnt.
