Title: Regulating device for an adjustable hydraulic pump with several consumers
Inventor: VAN BRACHT DETLEF
IPC: F04B49/08
Filed: 1998-09-24
Abstract: The invention relates to a regulating device for an adjustable hydraulic pump (1). Said device has a delivery flow control valve (15) and an output control valve (27). The delivery flow control valve (15) is subjected to the pressure difference between a first control line (18b) which is connected to the delivery line (5b) downstream of a metering throttle (6b), and a second control line (19) which is connected to the delivery line (5b) upstream of the metering throttle (6b). The delivery flow control valve (15) then regulates the adjusting pressure for an adjusting device (7) according to this pressure difference in order to adjust the delivery volume of the hydraulic pump (1). The output control valve (27) is situated between the first control line (18b) and a pressure medium tank (4). The control pressure in the first control line (18b) acts upon the output control valve (27) in the direction of opening and the adjusting device (7) acts upon the output control valve (27) by means of a spring measurement device (29) in the direction of closing. According to the invention, several consumers, each connected to the hydraulic pump (1) by a separate delivery line (5a-d) in which an adjustable metering throttle is located, can be controlled by the regulating device. A first control line (18a-18d) is connected to the delivery line leading to the designated consumer upstream of the designated metering throttle (6a-6d). A first pressure change device (17, 40, 41) selects the highest of the control pressures in the first lines (18a-18d) and conveys this to the delivery flow control valve (15). The output control valve (27) is only connected to the first control lines (18b, 18d) of the selected, output-controlled consumers, the first control lines (18a, 18c) of the remaining, non output-controlled consumers being separated from the output control valve (27).

Title: Alignment of optical building elements
Inventor: BLOM CLAES
IPC: H04W12/06
Filed: 1998-06-17
Abstract: When finely aligning an optical fiber (7), attached in groove (9) of a carrier (1), with a surface area of an optical element (5) such as a laser, the plateshaped carrier is plastically deformed by having suitable tools displace or act on the carrier at the end of the fiber (7), within a deformation region (17). For facilitating the plastic deformation slots (15) are made around the deformation region (17), so that a weakened area (16) is obtained quite at the end surface of the fiber (7). The fine alignment can be made either for correcting the position of erroneously mounted optical building elements or for a fine alignment of building elements, which have been mounted without necessarily trying to achieve a very high accuracy. The very alignment procedure can be executed when simultaneously measuring the efficiency of the interface, by activating the laser (5) to emit light into the optical fiber (7). This light can be detected by a light detector (25), so that the deformation process can be made in order to obtain maximum output power at the end of the fiber (7). The material of the carrier (1) can be a metal having a high degree of purity, for example copper plate of a small thickness. The fine alignment procedure as described provides advantages both in economy and in the degree of accuracy in the alignment operation, so that little attenuation is obtained in the interface between the building elements in the finished product. The carrier together with the building elements is intended for being moulded into a capsule in order to obtain an optical component suited to be mounted on a circuit board.

Title: Automatic train serialization with car orientation
Inventor: LUMBIS ANTHONY W
IPC: B61L15/00
Filed: 2000-02-17
Abstract: A method of serialization including establishing a parameter along a length of the train between a node on one of the cars and one end of the train. The presence or absence of the parameter at each node is determined and the parameter is removed. The sequence is repeated for each node on the train. Finally, serialization of the cars is determined as a function of the number of either determined presences or absences of the parameter for each node. The parameter can be established by providing at the individual node, one at a time, an electric load across an electric line running through the length of the train and measuring an electrical property, either current or voltage, at each node. The same process is used to determine the orientation of a car. The operability of each node is determined by counting the presence and then the absence of a parameter along the whole train.

Abstract: In an HF alkylation process where an acid catalyst regeneration column separates HF acids from ASO and water to provide regenerated catalyst for a catalyst circulation stream, and where buildup of ASO in the catalyst circulation stream is encountered, an improved control scheme uses an on-line analyzer/controller to maintain desired concentrations of HF acid, or ASO or water in the catalyst circulation stream. In one embodiment, a continuously flowing catalyst slip stream is piped to the analyzer/controller for simultaneously determining concentration of HF acid, ASO and water, and in a preferred embodiment the ASO concentration is maintained at a desired low level by manipulating temperature of a stripping fluid charged to a lower section of the column. An alternate manipulated variable is temperature of the acid catalyst feed to the regenerator column. Alternate controlled variables are the HF acid, and water concentration in the catalyst circulation stream.

Title: A method of managing one or more services provided over a communications network
Inventor: SHORE MARK M
IPC: H04L12/24
Filed: 2000-12-06
Abstract: Service providers such as Internet Service Providers (ISPs) and other communications service providers are faced with increasing management problems as use of their services becomes more popular. Service level agreements (SLAs) are typically drawn up between a customer such as an enterprise, and a service provider and these SLAs set out the definitions of the service that the provider agrees to give. Different classes of service such as premium rate and best effort services may be provided by service providers and this adds to management complexity. A formalised model or representation system is described for representing information about services such as information from service level agreements and definitions of classes of service. This formalised model is then mapped onto a model of a communications network in order to determine a relationship between the services and the communications network. The determined relationship is then used to assist negotiation of service level agreements;  to automatically generate configuration details to enable services provided on the network to meet SLA commitments; and to automatically configure operations support systems, such as fault and performance monitoring systems.

Abstract: Apparatus and method for non-invasive diagnosis of cardiovascular and related disorders. The system establishes a correspondence between the dynamics of the wave contour of the arterial pressure pulse and the associated disease states. The system comprises an input module, a contour signal receiver, and a processing module. The input module utilizes a pressure transducer for taking a non-invasive measurement of the arterial pulse. The contour signal receiver amplifies, digitizes and normalizes the arterial pressure pulse signal. In the processing module, the normalized arterial pressure contour is subjected to wavelet analysis, which transforms the dynamics of the time series of arterial blood pressure contour into multi-resolution wavelet coefficients or signatures. The processing module includes a neural network which is trained to associate the diagnostic features of the transformed arterial pressure contour embedded in the coefficients with a disease condition. After the learning phase, the system is capable of diagnosing known cardiovascular conditions in patients.
