Title: Leaktight fitting for a shaft end
Inventor: LETURCQ MICHEL MARIE MAURICE
IPC: F16J15/32
Filed: 1998-08-04
Abstract: The present invention relates to a leaktight seal with a lip (25) capable of gripping a shaft end (15) and fitted behind a cap (26). When the cap (26) is in place covering the shaft end (15) and closing the housing (8), it presses on a stop flange (23) of seal (20) and pushes the lip (25) outwards so that the rotation of the shaft end (15) causes no wear to the seal. When the cap is removed, the housing (8) remains open but the lip (25) grips the shaft end and restores the leaktight seal. This fitting is of particular use for shaft ends (15) fitted with a key slot used for manually rotating a rotating machine during the inspection phase of servicing, the shaft end (15) being driven during normal use of the machine.

Title: Method and arrangement for determining the position of a mobile radio terminal
Inventor: EKMAN BO KENNETH
IPC: G01S5/10
Filed: 1997-02-12
Abstract: The present invention teaches a method, system, terminals and service node for geographically positioning a first mobile radio terminal within a radio network comprising unsynchronised radio base stations by using a plurality of second fixed radio terminals whereby the positions of the radio base stations and the second fixed radio terminals are known. First and second radio terminals measure the relative receive times between the timing signals downlink received from at least three radio base stations and the second fixed radio terminals send them to a service node in the network using them for calculating the transmission time offsets of the timing signals downlink. Calculating the position of the first mobile radio terminal is performed either in the service node in the network or in the terminal itself, after respectively sending relative receive time measurements from the first mobile radio terminal to the service node, or broadcasting transmission time offset values and known positions from the service node to the first radio terminal to be positioned.

Abstract: Apparatus (10) for generating a radar waveform (W). A noises generator (20) generates a series of pulses in a pseudo-random pattern, and a frequency generator (16) generates a carrier wave having a frequency within a predetermined band of frequencies. The carrier wave is modulated with the pseudo-random pattern of pulses, and the resulting modulated carrier wave passed through both a filter (30) and an attenuator (32) to suppress any discernible feature or signal characteristics of the resulting waveform. The modulated carrier is transmitted by an antenna (42) and a received return signal is processed by a signal processor (100) to obtain pertinent information about a target. The transmitted waveform has no discernible attributes by which the waveform, if processed and analyzed by someone else's radar detector (E) would convey any intelligence as to the presence or source of the transmitted waveform.

Title: Speech rate conversion without extension of input data duration, using speech interval detection
Inventor: IMAI ATSUSHI
IPC: G10L25/78
Filed: 1998-04-30
Abstract: When a delivered speed of a listening speech (speech speedy is slowed down, a connection order generator (8) always monitors a data length of input speech, an output data length calculated previously by a conversion function concerning a preset scaling factor, and a data length of actual output speech in predetermined processing unit, then decides connection order so as not to cause inconsistency among them. The speech data and the connection data are connected without omission of speech information by controlling a speech data connector (9). When power of an input signal data is calculated to discriminate a speech interval and a non-speech interval, a threshold value for power is decided according to a maximum value of the power and the difference between the maximum value and a minimum value.

Abstract: Message passing is suitably performed even if there are a plurality of server objects, and even if a processing request is received and a processing result is returned by different server object. When sending a message from a client object to a server object, a data area for storing a result of processing executed by the server object is reserved. In executing the processing by the server object, an authorization to return the processing result of the server object to the client object is delegated between the server objects. Then, the result of the processing executed by the object which was most recently delegated to possess the above authorization is stored in the data area. The client object then reads the data stored in the data area so. as to receive the processing result by the server object.

IPC: A61K39/00
Filed: 1997-08-12
Abstract: A new method to capture, purify and expand antigen-specific T lymphocites has been developed using magnetic beads coated with recombinant MHC class I molecules. This method was optimized using homogenous populations of naive T cells purified from mice transgenic for the 2C T cell receptor (TCR). These T cells were captured on beads coated with MHC class I molecules and the relevant antigenic peptides. MHC and peptide specificity was confirmed by the usage of irrelevant MHC peptide combinations. An enrichment of 800 to 1600 fold was measured, using 2C T cells mixed with irrelevant T cells, starting from a 2C T cell frequency of 1/3000. The same approach was used to purify antigen-specific CD8+ T cells from total CD8+ T cells from naive mice. The recovered cells could be expanded and specifically kill target cells in vitro; they had a significant effect in vivo as well. We expect this procedure to be suitable to purify and expand in vitro tumor- and virus-specific killer T cells for use in cell therapy.
