Granted: 2006-07-11
Abstract: In a process for purifying a carboxylic acid fraction obtained by liquid phase carbonylation of an alkyl alcohol and/or its reactive derivative in which volatile iridium- and/or volatile co-promoter contaminants are converted to involatile forms by contacting with an iodide in the absence of carbon monoxide or at a partial pressure less than that of the carbonylation reaction.   The involatile contaminants are then separated from the carboxylic acid.

Abstract: An operations facility is provided for administering unsubscribed telephone lines and conserving the use of telephone numbers associated with suchlines by associating a plurality of unsubscribed lines with the same telephone number and same switch line termination point. Advantageously, then, a plurality of unsubscribed lines may be inexpensively provisioned with soft dial tone, therebyallowing a potential telephone subscriber to interactively subscribe to and activate telephone service from an unsubscribed line. Moreover, the application of soft dial tone may be used to identify a network access endpoint that is being used by a customer, and thus improve the accuracy of the contents of databases used by theoperations facility in the provisioning of telephone service by identifying incorrect data.

Title: Digital signal recording apparatus in which interleaved-nrzi modulation is generated with a lone 2t precoder
Inventor: KIM SOON-TAE
IPC: G11B20/14
Filed: 1995-09-27
Granted: 2002-04-23
Abstract: A lone precoder of 2T type generates interleaved non-return to-zero, invert-on-ONEs (I-NRZI) modulation for digital signal recording apparatus used for recording in parallel tracks on a record medium, the interleaved codes providing for the inclusion of pilot signals in selected sets of recording tracks. A first set of NRZI codes is generated directly by the precoder, and a second set of NRZI codes. Preferably the lone 2T precoder is one that performs its coding of each information word on a parallel-bit basis, to implement pipeline processing of the generation of I-NRZI modulation, and to avoid the need for intermittently written or intermittently read buffer storage. The digital signal recording apparatus is suited for the recording of television signals, with pilot signals being included on the tracks when sync and run-up data are recorded, as well as when video and audio data are recorded.

Abstract: A Radiology Healthcare Network provides high quality, timely medical interpretations of radiological images on a national (e.g,, across the U.S.) and regional basis. The images can include images created by conventional x-ray technology, computed radiography, magnetic resonance imaging (MRI), computed tomography (CT), ultrasound imaging, nuclear medicine, and mammography equipment. The invention includes the acquisition of these images from health care facilities, the conversion of these images to digital format, the routing of these converted images, the interpretation of these routed images, and the routing of the interpretations back to the originating facility. The images are routed (e.g., on a variety of high-speed digital and analog telecommunication networks) to the appropriate interpretation resource by an administrative site on the Network based on one or more requirements associated with the radiological study. The interpretation can be performed on high-resolution workstations and/or on films produced by film printers. The invention can include quality control measures which assure high image and interpretation quality. The control and tracking of images by the administrative site results in the production of a complete, signed interpretive report in a timely manner.

Title: Means for and method of controlling frame rise in vehicle suspensions
Inventor: BARLAS SERGE ALEXANDER
IPC: B60G11/46
Filed: 1996-10-11
Granted: 2005-09-13
Abstract: Vehicles, notably heavy duty trucks, equipped with torque reactive suspensions, such as trailing arm air suspensions, are susceptible to driveline vibration and wheel hop due to engine produced torque. According to this invention such driveline vibration and wheel hop can be suppressed by preventing frame rise from occurring. Suppression can be accomplished by providing one of several forms of frame rise control means operative between the vehicle drive axle and the vehicle frame. One form of frame rise control means utilizes rebound control leaf springs on opposite sides of a vehicle. Another form utilizes shock absorbers each of which incorporates a spring mounted on the piston rod. Another form utilizes hydraulic cylinders, each having a source of pressurized hydraulic fluid connected to the chamber of the cylinder on the rebound side of the piston and the chamber on the opposite side of the piston vented to atmosphere. Another form utilizes hydraulic cylinders each having a source of hydraulic fluid connected to the chambers on opposite sides of the piston with a valve operative to block flow of hydraulic fluid from the chamber on the rebound side of the piston. Still another form utilizes an elongated endless elastic strap embracing the shock absorbers.

Abstract: The control system for an assembly to treat the surface of a moving polymer web material, through electrical discharge of a dielectric barrier in a controlled gas atmosphere, operates a series of actions if the substrate (3) speed through the appts. (2) exceeds a given speed, and if there is a stoppage and/or the substrate speed drops below the set rate. If the substrate (3) speed is too fast, the extraction system (9), gas feed (7) and electrical energy supply (8) are disengaged in sequence. On a stoppage or reduced travel speed, the electrical energy supply (8), gas feed (7) and exhaust system (9) are interrupted in sequence.   Preferably the control unit (10) is structured to set in train the disengagement and interruption of the operations, in the required sequence, according to the deviation of substrate (3) speed from the nominal values. The gas feed (7) has a throttle (14). The feed delivers a carrier gas and an oxidising gas (15,16). On a command from the control (10), the throttle blocks the gas flows for the time span set by it according to the condition.
