Abstract: A heater (seed) and system for subjecting tumors to closely controlled hypothermia or higher temperatures includes a core of ferromagnetic material having a high resistivity or resistivity of a non-­conductor enclosed with a bio-compatible non-magnetic conductive sheath and excited by a coil positioned to establish a magnetic field coupled to the seed. The core is dimensioned so as to reduce demagnetizing effects to acceptable levels. The thickness of the conductive sheath is optimized to achieve a heat generating capacity which is considerably greater than that of the bare ferromagnetic material.

Abstract: Disclosed is an apparatus for measuring particles or particulates in a fluid in a measuring cell (4) provided with a measuring window (5, 6) through which a laser beam (22) is projected or through which light scattered from the particles passes. The surface (r1,r2) of the measuring window is spherical with a radius of curvature whose center is at a point (a) on which the laser beam converges for measurement. With this arrangement, light focused on the convergence point or light coming from the point always passes through the interface between the window and the fluid in the cell at an angle that is normal thereto. Thus no refraction of the light passing through the window occurs at the interface with the result that fluctuations of the refractive index of the fluid in the cell do not effect the focusing point of the light.

Abstract: Probes (18A,18B,18C) can be interchangeably mounted in the spindle (12) of a machine tool. Each probe has an optical signal transmission system, in which an optical signal from a light emitting diode (24) is transmitted to a receiving photodiode (26). To prevent interference between the different probe signals, each probe modulates the emitted light at a different carrier frequency. The receiver (28) contains electronic bandpass filters to separate out the different carrier frequencies. The signal information is encoded onto the optical signal by phase modulation of the carrier frequency.

Abstract: 4-methyloxybenzyloxycarbonyl (Moz) is used to protect the alpha amino groups of the amino acids used in solid-phase synthesis of thymosin α₁. It was found that the Moz group can be removed rapidly and completely with 5-10% trifluoroacetic acid in CH₂Cl₂. Some advantages of utilizing Moz-amino acids over Boc-­amino acids in solid-phase peptide synthesis are higher yields and purities with reduced consumption of trifluoroacetic acid during the acidolytic cleavage of the N α -Moz groups. Further improvements with respect to the recovery and recycling of the used solvent are obtained by using tributylamine in place of triethylamine as the neutralization agent making it possible to distill methylene chloride from the liquid waste without contamination by the lower boiling triethylamine. Methylbenz­hydrylamine resin is the preferred resin support. Cleavage from the resin support and deprotection of the protected side groups of the protected thymosin α₁ can be accomplished using either HBr or trifluoromethane sulfonic acid in trifluoroacetic acid with anisole and thionanisole as scavengers.

Abstract: An apparatus and method for manufacturing a ceramic superconductor coated metal fiber (16) comprises a container (12) for holding a nonaqueous solution in which particles of superconductor material are colloidally suspended to form a slurry (14). A voltage source (24) is provided to influence the slurry (14) with an electric field and a magnet device (44) is provided to influence the slurry with a magnetic field. The magnetic field is oriented relative to the fiber to align the superconductor particles of the slurry (14) in a desired orientation for subsequent attachment onto the surface of the fiber (16). The voltage source (24) is connected to the metal fiber to electrically bias the fiber as it is drawn through the slurry (14). Consequently, charged superconductor particles in the slurry attach to the electrically biased fiber. Subsequently, the coated fiber (16) is heated to sinter the aligned particles and establish a ceramic superconductor shell on the metallic fiber substrate.
