Abstract: Methods and compositions are described for nonliposomal lipid complexes in association with toxic hydrophobic drugs such as the polyene antibiotic amphotericin B. Lipid compositions are preferably a combination of the phospholipids dimyristoylphosphatidylcholine (DMPC) and dimyristoylphosphatidylglycerol (DMPG) in about a 7:3 mole ratio. The lipid complexes contain a bioactive agent, and may be made by a number of procedures, at high drug:lipid ratios. These compositions of high drug:lipid complexes (HDLCs) may be administered to mammals such as humans for the treatment of infections, with substantially equivalent or greater efficacy and reduced drug toxicities as compared to the drugs in their free form. Also disclosed is a novel liposome-loading procedure, which may also be used in the formation of the HDLCs.

Abstract: ABSTRACT OF THE DISCLOSURE      A system that provides a signal in an assigned time slot of a multi-time slot repetitive frame, the assigned time slot being determined by input data that changes only on occasion, includes a flywheel circuit for reducing the chance that intermittent errors in the data input may cause the signal to be provided in an incorrect time slot.  The flywheel circuit includes a time slot counter synchronized to provide a zero count during the assigned time slot and to initiate an output signal whenever the zero count occurs.  The timing of a particular count of the counter is compared to the timing of the signal from the system during each frame, and if the timing does not correspond in a predetermined manner for a predetermined number of consecutive frames, the counter is re-synchronized to the timing of the signal from the system.

Title: A method and device for processing an analog signal
Inventor: DENT PAUL WILKINSON
IPC: H04B1/64
Filed: 1991-06-17
Granted: 2000-03-07
Abstract: The invention relates to a device and a method for processing an analog input signal which varies widely in amplitude, such as speech, for the purpose of reducing the ratio of maximum to minimum amplitude variations of an output signal, after the processing, to the square root of the ratio existing before processing in order better to transmit said signal through a channel of restricted dynamic range in the presence of additive noise.      The device comprises an analog-to-digital converter arranged to change the input signal into a stream of integer numbers. The numbers in the stream represent in some proportional way the instantaneous value of the input signal divided by a reference voltage. This reference voltage is generated by a smoothed amplitude measuring device in proportion to the amplitude of the output signal that is produced, when the number stream is reconverted to an analog signal waveform by means of an digital-to-analog converter working with a constant reference voltage.      The invention also relates to a device and a method for processing a signal of compressed amplitude variation, such as might be produced by the method and device described above, in order to produce a signal of amplitude variation restored to the normal range, being the square of the compressed range.

Abstract: A system and method for detecting contraband generates a highly collimated beam (13) of pulsed fast neutrons, having a pulse width on the order of a nanosecond, and an energy of 5 to 9 MeV. An object (14) under investigation is scanned with the collimated pulsed beam. The neutrons in the beam cause (n, .gamma.) reactions in a limited object volume or voxel, defined by the inter-section of the collimated beam and the scanned object. The highly penetrating fast neutrons produce nuclear reactions with the atomic elements present within the object, causing gamma rays to be emitted.  The gamma rays are detected in a gamma ray detec-tor (20). The approximate time of flight of the neutron pulse is measured, allowing a determination to be made as to the particular voxel from which the gamma ray originated. The energy of the detected gamma rays identifies the particular elements from which the gamma rays originated. Thus, e.g., the carbon, nitrogen, oxygen, and chlorine content, which elements are commonly found in contraband, of a particular voxel can be determined directly and precisely.  The voxel content information may be combined from a substantial sample of the voxels that make up the object to provide a direct indication of the elemental content of the object, and hence whether contraband is present or absent within the object.

Title: Process for the detection of a nucleotidic sequence by use of the sandwich hybridation technique
Inventor: CROS PHILIPPE
IPC: C12Q1/6886
Filed: 1991-06-11
Granted: 2003-01-07
Abstract: A method for detecting a single-stranded nucleotide sequence in a sample which is known or thought to contain it, using sandwich hybridization comprising the step of incubating the sample with a capture probe which is passively fixed to a solid support and with a detector probe which is labelled with a non-radioactive marker. The capture and detector probes can hybridize with two non-overlapping regions respectively of the target nucleotide sequence being sought. The incubation step is followed by a washing step for removing reagents which have not been fixed by hybridization. The method is characterized in that the capture probe contains 9-30 nucleotides and is fixed to said solid support which is made of a material based on a hydrophobic compound. The method can be used particularly for diagnosing infectious or genetic diseases and for cell typing.

Granted: 1996-01-02
Abstract: The invention is an improvement in an AC adjustable frequency load-moving system of the type having a control circuit providing a motor speed signal and using command ramps to control each of plural AC squirrel cage motors. The invention helps assure substantially equal load sharing by the motors.  The improvement includes a dwell circuit which maintains the motor speed reference signal at a synchronizing value at least for a period of time denominated as the dwell time.  This permits microprocessors -- which may be running asynchronously --to both "read" the same value of motor speed signal even though such value may be read at slightly different instants.  Separate inverter units monitor such signal and responsively generate synchronized command ramps to effect load sharing.  The invention is suitable for use with a wide variety of plural-motor drive systems and has been found to be particularly suitable for use on crane hoist systems.
