Abstract: The invention relates to a humanized monoclonal antibody or fragment thereof which specifically binds to human interlukin-2 (IL2), whereby said humanized monoclonal antibody neutralizes the activity of human IL2 by binding to the human IL2 prior to, during, and/or subsequent to the binding of the human IL2 to the human IL2-receptor, and wherein the light chain variable region of the humanized monoclonal antibody comprises in its second framework region the contiguous amino acid sequence KAPKA at amino acid positions 42-46.

Abstract: A method and system for identifying conflicting resource claims by applications for a system having a plurality of resources. A set of schemas are predefined for the system, wherein each schema defines a pooling of the resources of the system. Each application is then created based upon one of the schemas so as to be associated with a specified pool or subset of device resources. Applications are executed by a browser. Each application may have more than one state, and each state may have an associated schema. Requests for changes of state, such as invoking an instance of the application, are received by the browser. The browser informs a resource manager of the associated schema and the resource manager identifies the pool or subset of resources for requested state change based upon its schema and determines whether or not the resources are currently in use by another active application. Conflicts may be resolved by a conflict resolution component.

Abstract: The present invention provides a system with a redirect functionality that removes the potential of a bottleneck inherent with a central redirect server. In a communications system according to the present invention, the central redirect server is eliminated in favor of a distributed redirect server. This distributed redirect server is distributed to, and hosted on, telephony access nodes (TANs) in the system. This configuration resolves both the problem of a potential bottleneck and provisioning of redundant redirect server capability.

Abstract: The present invention provides a telephony-accessed application system for providing a service, such as voicemail, in accordance with a switching interface such as in the ITU-T H.323 or IETF SIP recommendation. Queuing functionality is made possible in a system which employs a switch which does not support queuing. The queuing functionality is made possible by a queue means which is provided within an application means, i.e. the voicemail means itself. Consequently, the switch itself is relieved of the burden of having to keep track of the exact status of each of its ports at all times. The high-level queuing is performed at a logical level rather than at the physical level, and therefore affords a cleaner interface. Furthermore, the implementation of the queuing functions in the terminating application means allows for the use of a wider variety of intermediate switch means in a network.

Abstract: The invention is system and method for detecting a leak and operating an existing valve in response to the detected leak. In this regard, a receiving unit may be installed on an existing shutoff valve. The valve may control the flow of a fluid into a site. A transmitting unit may be installed in the vicinity of an appliance receiving the fluid. The transmitting unit may include a detector capable of detecting the fluid. In response to the detector detecting the fluid, the transmitting unit may transmit a signal including a unique 32 bit code. A receiver within the receiving unit may be capable of receiving the signal. Additionally, a PIC microprocessor within the receiving unit may be configured to receive the signal from the receiver and determine if the signal contains the code. In response to determining the signal contains the code, the PIC may control a motor to operate (e.g., turn off) the valve. The motor may be configured for attachment to the valve via a coupler.

Abstract: An efficiency-maximization motor controller that includes a use method has power conveyance to an induction motor (1) with a digital signal processor (DSP) (8) that calculates and optimizes supply of current for existent motor loading from a power supply (2) and mains voltage through a control element (5). The control element can include a standard triac, a field-effect transistor, an insulated gate bipolar transistor, a 3 quadrant triac or other select control element. Digital calculation and motor-control feedback of current requirements for motor loading and other motor parameters are calculated in millionths of seconds to provide motor-current optimization for all motor-use conditions. Calculation of motor-load requirement for current and supply of that current are effectively simultaneous.

Abstract: A variable gain differential amplifier using a single operational amplifier. A potentiometer is used in the negative feedback loop with one end connected to ground through a resistor which limits the maximum gain. The other end is connected to the output and the wiper is connected through a minimum gain limiting resistor to the inverting terminal. This provides an amplifier with good CMRR, relatively low input impedance, wide gain control and variability with a single operational amplifier.

Abstract: The invention relates to the recovery of chlorine values as ferric chloride from iron chloride dust which is obtained as a by-product from the chlorination of a titaniferous material containing more than 5% by weight iron oxide, such as ilmenite. The method comprises heating the iron chloride dust to a temperature above 275.degree. C. in the presence of chlorine and iron oxide and recovering the ferric chloride volatilized from the iron chloride dust together with the ferric chloride obtained from ferrous chloride present in the iron chloride dust by reaction with the chlorine and ferric chloride obtained from other metal chloride contaminants by reaction with the iron oxide.

Abstract: The invention relates to a method for the reduction of ferric chloride to produce ferrous chloride. The method involves using as the reducing agent sulphur monochloride optionally in combination with sulphur or sulphur dichloride to produce ferrous chloride and sulphur dichloride. The sulphur monochloride may be introduced as a gas or as a liquid and the reaction is conveniently performed in a fluidized bed. According to a particular aspect, the ferric chloride reduction forms part of a process for the recovery of chlorine values from iron chloride by-produced by industrial processes such as the chlorination of a titaniferous or aluminous material.

Abstract: A process for the chlorination of a material containing iron and titanium chemically combined with oxygen, comprising feeding the material to be chlorinated, in particulate solid form, into a reaction bed of solids containing ferrous chloride, and reacting it within that bed, at a temperature below the melting point of ferrous chloride, with a controlled amount of chlorine in the presence of sulphur in free or combined form, to produce solid ferrous chloride, titanium chloride, which is volatile at a temperature of operation, and sulphur dioxide, as the principal products of the process.
