Abstract: A method for synthesis and purification of radiolabeled macroaggregated human serum albumin (MAA) to form a bulk solution injectable to a patient includes: providing a radiometal in a generator, the radiometal being a generator eluate; synthesizing the radiolabeled MAA in a reactor with MAA particles from a commercially available labeling kit for 99mTc and the generator eluate so as to provide synthesized radiolabeled MAA particles; passing the synthesized radiolabeled MAA particles on a syringe filter membrane having a membrane composition, diameter, and pore size for trapping the radiolabeled MAA particles as trapped radiolabeled MAA particles and not retaining impurities from a bulk solution, the impurities including free radioactive metal isotopes, parent radioactive metal breakthrough, and stannous chloride present in the MAA labeling kit for 99mTc; and untrapping the trapped radiolabeled MAA particles from the syringe filter using a saline or buffered solution passing through the syringe filter.

Abstract: The present invention relates to derivatives of 1-hydroxymethylene-1,1-bisphosphonic acid, the pharmaceutical compositions comprising them, and their application in therapeutics, particularly for the treatment of cancerous tumors. It is also directed to a methods of preparation of such derivatives.

Abstract: A supporting device is provided for mounting a receptacle or container to a supporting structure, such as a rail, balcony wall or other similar support structure. The supporting device has an adjustable retention member for receiving and retaining the receptacle and a mounting member for mounting the device to the support structure. The retention member is adapted to fit around the outer circumference of the receptacle to be mounted to securely retain the same. The mounting member is in cooperative engagement with the retention member and includes engaging means for releasably engaging the support structure.

Abstract: The invention concerns a system for controlling online and offline access to digital data using a software key server. It consists in controlling access to encrypted digital data or programs broadcast by satellite, cable or digital land-based network, using a server of decryption keys (8) whereto each reception terminal (2) must be connected with a single identification through a secure channel independent of the transmission channel to be able to use the transmitted data or programs. Said system is generally applicable to all types of digital data transmission, and in particular digital television programs or encrypted data broadcasting services.

Abstract: The invention concerns an in-flight encryption/decryption system for data distribution. It generally concerns the field of data transmission of all types in digital form using packet-data encoding consisting of data routed in blocks in a network, and in particular the distribution of encrypted data by satellite. To accelerate the key-exchanging period, the keys are not distributed on a channel parallel to the data channel but inside the very data, encrypted then transmitted in the form of packets (12) containing each a key (14) and useful data (15) encrypted with said key, the latter capable of being changed for each packet and being recovered in reception by a specific hardware or software element.

Abstract: The invention concerns a device for routing digital data flows. It consists of a box (4) equipped with a tuner (6′) connected to a satellite antenna (7′) or a data distribution network, a packet demultiplexer for receiving digital data, means for connecting it to a digital decoder (1) and to a computer (3), as well as a routing unit (9) for interconnecting all the digital flow inputs or outputs, from and to the digital decoder (1), from and to the computer (3), and from the tuner (6′). The invention concerns the digital transmission of all types of data, and in particular transmissions using packet coding consisting of a set of data routed in blocks in a network, whether radio, cable or satellite.

Abstract: The invention concerns a system for using a computer as server for television sets. It consists of a module (4) connected to the decoder (1) of the television set (2) and to the computer (3) by digital links, and comprising a micro-electronic component (5) provided with enhanced filtering units and an interface for controlling the computer resources from a decoder by means of a specific software integrated therein. The invention concerns reception on a television set of data of all types, and in particular programs or data using coding by packets consisting of a set of data routed in blocks in a network, whether of the wireless type, by cable or satellite.

Abstract: Disclosed are a method and a data-processing system for the acquisition of software programs by a microcomputer. The system comprises, for this purpose, a data base service center in which application software programs are stored and a removable electronic memory carrier containing rights of access, to be introduced into a drive of the microcomputer to enable the remote-loading, into the microcomputer, of software programs for which the carrier contains the corresponding rights of access, this same carrier being capable of containing the rights to run the remote-loaded software. The disclosed device can be applied to portable microcomputers.

Abstract: A high efficiency process for producing hydroxy-diphosphonic acid derivatives of higher carboxylic acids comprising a first step of mixing a tri-valent phosphorous compound with the higher carboxylic acid in a molar ratio in the range of 13:12 to 18:12, and subsequently heating the reaction mixture to a temperature of 80.degree. to 110.degree. C. for about 3 to 20 hours.In one embodiment, a subsequent solvolysis step is employed wherein the product resulting from the heating step is heated with a solvent having a hydroxyl function.
