Title: A system for preheating fuel
Inventor: GARCIA-MALLOL JUAN A
IPC: F23D1/00
Filed: 1998-06-02
Abstract: A system and method for preheating a mixture of fuel and air as the mixture is introduced into a furnace combustion chamber comprises passing the mixture through a nozzle extending into an upstream portion of an opening defined in a wall enclosing the combustion chamber.  The nozzle is sized so that an annular space is formed between the nozzle and the opening.  Hot air is introduced through the annular space and mixes with and preheats, in a downstream portion of the opening, the mixture passing through the nozzle.

Title: System and method of automatic call barring in a radio telecommunications network
Inventor: SPIES DAVID
IPC: H04W12/06
Filed: 1997-04-18
Abstract: A system for reducing fraudulent use of a mobile telephone number in a radio telecommunications network. The system automatically bars call originations from the mobile telephone if the mobile telephone does not register with the network for a predetermined time period, or if the mobile telephone does not originate a call for a second predetermined time period. The system determines when a mobile telephone originates a call, measures a predetermined time period with a timing mechanism, and starts the timing mechanism when the mobile telephone originates a first call. The system then determines whether a second call originated from the mobile telephone during the predetermined time period and restarts the timing mechanism at the time that the mobile telephone originates a second call upon determining that the second call originated from the mobile telephone during the predetermined time period. The system reauthorizes the mobile telephone to originate calls in the network upon verification of a personal identification number entered by the subscriber.

Title: Cancer immunotherapy using autologous tumor cells combined with allogeneic cytokine-secreting cells
Inventor: GRANGER GALE A
IPC: A61K39/00
Filed: 1997-07-25
Abstract: This invention comprises cellular vaccines and methods of using them in cancer immunotherapy, particularly in humans. The vaccines comprise a source of tumor-associated antigen, and a cytokine-secreting cell line. Tumor antigen may be provided in the form of primary tumor cells, tumor cell lines or tumor extracts prepared from the subject. In certain embodiments of the invention, the cytokine-secreting line is a separate tumor line that is allogeneic to the patient and genetically altered so as to produce a cytokine at an elevated level. Exemplary cytokines are IL-4, GM-CSF, IL-2, TNF-.alpha., and M-CSF in the secreted or membrane-bound form. In these embodiments, the cytokine-producing cells provide immunostimulation in trans to generate a specific immune response against the tumor antigen. Vaccines may be tailored for each type of cancer or for each subject by mixing tumor antigen with a favorable number of cytokine-producing cells, or with a cocktail of such cells producing a plurality of cytokines at a favorable ratio.

Title: Subscription management system for data communication network
Inventor: LEE RONALD CHI HONG
IPC: H04L12/14
Filed: 1999-04-14
Abstract: A network management system allows operators to set up subscriptions to services for network users.      The subscriptions each associate a subscriber object and an application object. The subscriber object contains information about the subscriber's network connection. The application object contains information about the application's network connection. The operator does not need to work with low level information such as physical port numbers to create a subscription. The system automatically sets up one or more virtual channel connections as needed to provide the application to the subscriber.      The system can be easier to operate accurately than current systems. The system may track and accumulate statistics on a service-by-service basis.      The statistics may be used to bill for individual services even if several different virtual channel connections are used to provide each service.
