Abstract: Conventional omnidirectional lamp light is converted into a narrowly focused, highly intense beam with a power comparable to certain types of lasers. The lamp light is collected and focused with conventional means into an optical coupling cone which condenses the conventionally-focused beam to a very small diameter for launching into a fiber optic cable. An optical terminator at the end of the optical fiber retains collimation of the beam and a power density comparable to certain types of lasers, such as those used in medical applications.
Abstract: A non-invasive clinical instrument provides for in vivo detection of a restriction in an artery. A microphone is applied to the body over the artery and generates a complex electrical signal which is processed to remove noise and amplified. A digital bandpass filter circuit includes a plurality of individual bandpass filters, each of which covers 1/3 of an octave and covers adjacent octaves to cover the complete spectrum between about 2 to 2,000 hertz. Switched-capacitor bandpass filters are used. Each three bandpass filters separated by one-third of an octave are connected such that setting the center bandpass filter automatically resets the two adjacent bandpass filters to cover a single octave in steps of one-third. The sensed signal which is an AC analog signal is transmitted by an analog low pass filter to block undesirably higher frequency components from the digital filters. Digital low-pass filters connect the analog low-pass filter to the bandpass filters.
Abstract: A single wire electrode is supported at one end by a cylinder cap which has pins for guiding the electrode into an upwardly opening fusion chamber defined by a heavy metal cylinder. In a second embodiment, multiple secondary wire electrodes are spaced circumferentially about a central primary wire electrode. In a third embodiment, a laminate wire mesh electrode assembly is mounted within a rectangular cartridge fusion chamber.
Abstract: A glass slide has parallel tubular electrodes for performing electro cell fusion. Fluid may be pumped through the electrodes to dissipate heat to enhance the yield of viable hybrids. An alternate embodiment sandwiches a gasket and parallel tubular electrodes between glass slides to permit cell fusion in a closed sterile environment.
