Title: Polymer hydration method using microemulsions
Inventor: JONES THOMAS A
IPC: C09K23/00
Filed: 2006-09-22
Abstract: Long-chained polymer compounds are useful to viscosity aqueous brine fluids so that they can function as drilling fluids, completion/workover fluids, fracturing fluids, agricultural products, cleaning compounds, etc. These polymers may be hydrated with a microemulsion or lactescent emulsion prior to being added to the target fluid. The rate and completeness of hydration by this method are controlled and improved. In one non-limiting embodiment the microemulsion includes a polar hydrocarbon component, a nonpolar hydrocarbon oil, a small amount of water, a surfactant and optionally a co- surfactant.

Title: Telecommunications services apparatus and method
Inventor: WILSON JEFFREY
IPC: H04M1/64
Filed: 2008-06-17
Abstract: An apparatus for processing communications from an originator to a recipient in a telecommunications network is described. The apparatus comprises a memory for storing an availability status indicator for a recipient of communications and a service processor. The service processor is operable to receive an indication that a communication for the recipient has been received by the network in any one or all of a number of different communication formats, e.g. text message formats or a voice call format, to determine from the availability status indicator for the recipient whether the intended recipient is indicated as being unavailable to respond to the communication, and on determining that the intended recipient is indicated as being unavailable to respond to the communication, to instigate delivery of an outgoing text message (SMS, MMS or e-mail) to the originator. Thus subscribers of the network can readily configure a text-message "Out of Office" type reply to communications directed to them in any one of a number of different formats.

Title: Charge pressure limiter for torque converter with bypass clutch
Inventor: FRAIT STEVE ANATOLE
IPC: F16H61/14
Filed: 2008-11-26
Abstract: A system for controlling hydraulic fluid supplied to a torque converter which has a bypass (lock up) clutch having a variable torque capacity is able to limit the hydraulic pressure in the torque converter chamber when the clutch is activated. The system includes a source 112 of variable control pressure TCCZ, and a latch valve 84 which changes in response to the variable control pressure TCCZ alternately between an unlatched state, in which the output pressure TCCL from the latch valve 84 is low, and a latched state, in which the output pressure TCCL is high. A first valve 80 limits hydraulic pressure in the torque converter chamber alternately at two magnitudes of pressure in response to the low or high pressure output TCCL, and a second valve 82 responds to the variable control pressure TCCZ to regulate the hydraulic pressure CAPY that actuates the bypass clutch and changes the torque capacity of the clutch.

IPC: G01R31/02
Filed: 2009-06-25
Abstract: An apparatus (10) for testing automotive relays comprises: a first socket (6) having first to fourth connectors (6A-6D) for connecting to the terminal blades of a four-bladed plug-in Mini relay (2); an activating circuit (30,30,32,14,16) operable to apply a voltage between the first and second connectors (6A.6B); and a checking circuit (30,30,32,14,22,38) for checking for continuity between the third and fourth connectors (6C,6D). The first and third connectors (6A,6C) are interconnected so that, when a voltage is applied by the activating circuit between the first and second connectors (6A,6B), that voltage is also applied between the third and second connectors (6C,6B). A second socket (7) is provided having first to fourth connectors (7F-7l) for connecting to the terminal blades of a four-bladed plug-in Micro relay (4). The first and third connectors (6A,6C,7F,7H) of the two sockets are interconnected; the second connectors (6B,7G) of the two sockets are interconnected; and the fourth connectors (6D,7I) of the two sockets are interconnected. The apparatus can therefore test differing standard configurations of automotive relays.

Title: High-energy dual-energy CT system showing base material coefficient distribution
Inventor: ZHANG LI
IPC: G01N23/04
Filed: 2009-08-06
Abstract: An image reconstruction method in a high-energy dual-energy CT system involves scanning an object 200 (such as a large cargo) with high-energy (over 1 MeV) dual-energy rays, such as from x ray source 100, to obtain high-energy dual-energy projection values. It also calculates projection values of base material coefficients corresponding to the dual-energy projection values on the basis of a pre-created lookup table or by analytically solving a set of equations, and obtains an image of base material coefficient distribution based on the projection values of base material coefficients. The method is useful for substance identification and contraband inspection. The lookup table can show correspondence between high and low energy projection values and different combinations of thicknesses.

Title: Improvements in or relating to carrier current signalling systems
IPC: H04J1/18
Filed: 1948-04-12
Abstract: 651,992. Telephone transmission systems. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 12, 1948, No. 10085. Convention date, April 16, 1947. [Class 40 (iv)] [Also in Group XL (c)] In a carrier-wave signalling system in which both side-bands are transmitted but the carrier is suppressed at the transmitter, the signals are reduced in frequency in the receiver by beating with a local oscillator 6 in a mixer 1 and the upper side-band removed by means of a lowpass filter 2. The remaining lower side-band is demodulated in a second mixer 3 by beating against a further local oscillator 7. The removal of one side-band, in this manner, avoids the necessity for accurate phase-relationships between the demodulating oscillators and the incoming signals. The invention may also be applied to a multi-channel system in which each side-band comprises a number of sub-carriers, each modulated with a separate signal. To avoid the necessity for employing oscillators at the receiver which differ in frequency from those at the transmitter, all the channels may be shifted in frequency at the transmitter by a further amount g, the source 6 for each channel then comprising the particular channel carrier frequency Pe and the source 7 having the frequency g.

Abstract: 1470721 Sensor of oxygen partial pressure FORD MOTOR CO Ltd 13 March 1975 [23 April 1974] 10471/75 Heading G1N A sensor for determining the partial pressure of oxygen in the exhaust of an internal-combustion engine operating in the fuel-lean regime of air/fuel input ratios, and hence for obtaining a measure of the air/fuel ratio itself, comprises a cobalt monoxide ceramic sensing element 32 in a housing which permits exposure of the element 32 to the exhaust gases when the sensor is mounted in the exhaust conduit. The element 32 has two spaced electrodes, e.g. of Pt wire bonded by means of Pt paste, and exhibits a resistance which varies logarithmically with oxygen partial pressure in a relatively temperature-independent. manner when operated at temperatures above about 900 C. In order to reach this temperature rapidly a heater coil 48 is preferably incorporated in the housing, which may as shown include an inner cylinder 34 receiving the element 32 on a support 36 and exposing the element 32 through window 40. An outer cylinder 52 with transversely opposed windows 54 protects the entire arrangement, including the heater coil 48. Fig. 3 illustrates a circuit utilizing the cobalt monoxide resistor element 132 to monitor the intake air/fuel ratio and preferably to automatically regulate it at a desired value in the fuel-lean regime. Element 132 forms a sensor voltage divider with fixed resistor 76, and a reference voltage divider is provided by fixed resistor 70 and variable resistor 72, the value of which is set to obtain at junction 78 a voltage corresponding to the desired exhaust-oxygen partial pressure, and hence the desired intake air/fuel ratio. Operational amplifier 80 receives the voltage from reference junction 78. as well as that from the junction 82 of the sensor voltage divider, and produces a signal at output 58 whose polarity and magnitude indicate any excursion of the intake air/fuel ratio from the desired value. This may be used merely to monitor such excursion or, preferably, may be used to automatically control the air or fuel input rate so as to reestablish the desired ratio.
