Patent EP-0510086-A4 (EP)
Title: Interdigitation-fusion liposomes and gels
IPC: A61K51/00
Filed: 1991-01-11
Abstract: This invention relates to interdigitation-fusion (IF) liposomes and gels. These liposomes and gels capture high solute to lipid ratios, including bioactive agent. This invention also relates to the discovery that the fusion of liposomes to produce IF gel and liposomes according to the present invention is size dependent. The present invention also relates to a method for producing IF liposomes and gels. In the method of the present invention, sized liposomes formed by sonication, extrusion or alternative processes are fused in the presence of ethanol or other suitable inducer. This process results in a composition of the present invention in gel form. To produce liposomes, the gels are exposed to a temperature usually but not necessarily above the transition temperature (Tm) of the lipid used. The temperature required by the methods of the invention is that temperature which induces a change in the material properties of the mixture. The inducer may also be removed. The result is a composition comprising liposomes containing high solute to lipid ratios. The IF liposomes and gels of the present invention may be used in combination with numerous solutes, especially including bioactive agents.

Patent EP-0535160-A4 (EP)
IPC: G01T1/17
Filed: 1991-04-26
Abstract: An intraoperative radiation probe is devised to detect radiolabelled malignant tissues by being selectively sensitive to beta radiation while insensitive to gamma radiation. The probe is comprised of two plastic scintillators (12, 14) optically coupled to corresponding photomultiplier tubes (22, 24) via corresponding light pipes (16, 18). One of the plastic scintillators is shielded (38) against beta radiation while the other is left to detect both beta and gamma radiation. The gamma radiation sensitivity of the dual probes is empirically established and used as a weighted factor to subtract the outputs of the two probes to leave a signal indicative of the beta radiation emitted by the radiolabelled tissue. Because of the shorter range of beta radiation within tissue, only near radiolabelled tissue is detected by the probe while strongly radiolabelled, more distant tissues exposing the probe to gamma radiation are ignored. The reliably identified near radiolabelled tissues can then be surgically removed. The probe is usable in any application where local beta radiation is to be differentiated from other types and sources of radiation.

Patent EP-0684887-A4 (EP)
Title: Method and apparatus for repairing damaged tubes.
Inventor: FINDLAN SHANE J
IPC: B23K26/00
Filed: 1994-02-10
Abstract: Disclosed is a laser beam welding technique which can be utilized to accomplish clad welding and repair of the internal surface of a tube. The technique uses the addition of filler metal to build up the internal surface of the tube. The apparatus includes a laser energy source connected to an elongated weld head by an optical fiber. The elongated weld head is rotatable and contains a mirror canted at a forty-five (45) degree angle. The laser beam generated by the laser source enters the weld head through a rotary joint, passes through focusing lenses, and is reflected to the interior surface of the damaged tube by the canted mirror. Means are provided to rotate the weld head which causes the beam to travel circumferentially around the interior of the tube. Means are also provided to feed metal fill material to the location where the focused beam contacts the interior surface of the tube. The result is a smooth clad welding repair on the inside surface of the tube which restores the strength of the tube and leaves no crevices for future corrosion attack. In addition, the internal diameter of the tube is very close to the original diameter of the tube thus obviating pressure drop associated with the sleeving type repair and allowing for subsequent repair of the tube at positions beyond the first area of repair.

Title: Process for producing carboxylic acid derivative.
Inventor: TAKASE AKIRA
IPC: C07C249/12
Filed: 1994-07-01
Abstract: A process for producing a carboxylic acid derivative represented by general formula [VIII], (wherein R<1>, R<2>, R<3> and L are each as defined in the specification), which comprises reacting a benzyl halide with a cyano compound to give a phenylacetonitrile, reacting the nitrile with an alkyl nitrite in the presence of a base to give an  alpha -hydroxyiminophenylacetonitrile, reacting the hydroxy nitrile with an alkylating agent to give an  alpha - alkoxyiminophenylacetonitrile, hydrolyzing the alkoxy nitrile in the presence of a base, optionally after hydration and acid treatment, to give an  alpha -alkoxyiminophenylacetic acid, and finally reacting the acid with a halogenating agent, or converting the acid into a corresponding metal salt and reacting the salt with an alkylating agent, or reacting the acid with a lower alcohol in the presence of an acidic catalyst. According to this process, the reactions can be advanced through the respective steps under mild conditions, and the target derivative [VIII] can be produced even without resort to high-pressure steam equipment, high-temperature heat medium equipment, refrigerator, and so forth. Further, this process is advantageous in that only a single solvent will suffice without the necessity for using various solvents according to the respective steps. <CHEM>

Title: Compositions and methods for eliciting ctl immunity
Inventor: VITIELLO MARIA A
IPC: C07K14/02
Filed: 1995-02-16
Abstract: Cytotoxic T lymphocyte responses are effectively induced to an antigen of interest, particularly viral, bacterial, parasitic and tumor antigens. Compositions, including pharmaceutical compositions, of CTL-inducing peptide and an adjuvant or a lipidated peptide which induces a helper T cell (HTL) response stimulate the antigen specific CTL response. Among the viral antigens to which the CTL responses are effectively induced in humans are those of hepatitis B. The CTL response may be optimized by a regimen of two or more booster administrations. Cocktails of two or more CTL inducing peptides are employed to optimize epitope and/or MHC class I restricted coverage.

Title: Flash memory system having reduced disturb and method
Inventor: ROOHPARVAR FRANKIE F
IPC: G11C16/26
Filed: 1996-07-29
Abstract: A flash memory system having a reduced tendency to have its erased cells disturbed during read operations. An array of flash memory cells are arranged into a multiplicity of rows and columns, with all of the cells located in one of array rows has a control gate connected to a common word line and with all of the cells in a column has a drain connected to a common bit line. Control circuitry is used for carrying out memory operations, including program circuitry for programming cells of the array based upon a program input address and read circuitry for reading cells of the array based upon a read input address. The read means functions to apply a read voltage to a selected one of the word lines of the array as determined by the read input address. Disturb limit circuitry is used for limiting the time period that the read circuitry applies the read voltage to the selected one of the word lines.
