Patent EP-0113759-A4 (EP)
Title: Optical disc write/read employing passive focus maintenance.
Inventor: HOWE DENNIS GEORGE
IPC: G11B7/09
Filed: 1983-06-28
Abstract: Method for maintaining a write/read light beam (B) in sharp focus on the information surface (41) of a rotating flexible optical disc (13) notwithstanding variations in the thickness of the disc's support (43) which alter the distance between such inforamtion surface and a focusing lens (9) for the light beam. Such method comprises the steps of (a) directing the write/read light beam through the disc's support, and (b) positioning the disc relative to the focusing lens so that the disc's neutral plane (NP) is spaced from the lens by a distance equal to FL-(t/n - t/2), where FL is the focal length of the lens, and t and n are the nominal thickness and refractive index of the disc support (43), respectively. By such a method, variations in the support thickness and spherical aberrations induced thereby cause the spot focus to remain in focus on the disc's information surface without any need for refocusing the lens or repositioning the lens relative to the disc.

Title: Low trauma blood recovery system
Inventor: STEG ROBERT F JR
IPC: A61M60/36
Filed: 1993-07-02
Abstract: Recovery of blood from a wound site (12) during a surgical procedure is accomplished with low blood trauma that enables collection of increased amounts of blood having relatively little structural damage for return to the surgical patient. Blood trauma is decreased by accelerating liquid blood from the wound site to flow at a relatively low velocity with a relatively high negative gauge pressure and accelerating a mixture of blood and foam from the wound site to flow at a relatively high velocity and a relatively low negative gauge pressure. A suction wand (84) is provided in which liquid blood (32) is separated from a mixture of blood and foam (16) at the wound site through the transport of the two separated fluids at the different velocities and negative gauge pressures. The wand (84) includes an outer blood foam tube (110) within which are three resiliently compressed, side-by-side tubes (32, 44, 56) for handling liquid blood, rinse solution and anticoagulant. Low fluidic capacitance filter defoamer modules (120, 122), having built-in diaphragm operated pumps (136, 138), receive and filter recovered liquid blood and foam blood for transfer to separate storage bags (21, 37). Blood trauma is decreased by flowing the blood from the wound site to a liquid blood suction conduit (34) at relatively low rates of acceleration as the velocity of the blood changes from zero to about one meter per second with a relatively high negative gauge pressure, and flowing a mixture of  blood and foam from the wound site to a blood foam suction conduit (18) at a relatively high rate of acceleration as the velocity of the blood changes from 0 to about 45 meters per second with a relatively low negative gauge pressure.

Title: Boron-containing hormone analogs and methods of their use in imaging or killing cells having hormone receptors
Inventor: HAWTHORNE M FREDERICK
IPC: A61K49/00
Filed: 1995-05-15
Abstract: Boron containing compounds are targeted to hormonally responsive cells by contacting the cells with a conjugate of a boron containing moiety conjugated to a ligand having binding specificity for an intracellular receptor of the cell. The conjugates are useful for imaging or killing hormonally responsive cells, such as hormonally responsive tumor cells. For target cell killing, the cells are contacted with a 10B containing moiety conjugated to a ligand having binding specificity for an intracellular hormone receptor of the cells. The 10B containing moiety becomes associated with the hormone receptor of the cells, which may then be irradiated with neutrons to kill the cells by boron neutron capture. For target cell imaging, the cells are contacted with a 11B containing moiety conjugated to a ligand having binding specificity for an intracellular hormone receptor of the cells, and the boron that becomes associated with the hormone receptor of the cells may then be imaged using magnetic resonance imaging techniques.

Filed: 1996-08-08
Abstract: A fractal-shaped element may be used to form an antenna (510A, 510B, 510B', 510C), an element in an antenna system, a ground counterpoise in an antenna system, a resonating system, or a combination of any or all of these elements. Fractalizing such systems can substantially reduce the physical size while preserving desired impedance and gain characteristics. For example, a fractalized antenna system for a cellular telephone may be fabricated within the telephone housing (500). The fractal component (510A, 510B, 510B', 510C) need not be planar and may be fabricated using printed circuit board or semiconductor fabrication techniques. Changes in spaced-apart or rotational proximities in an antenna or resonating system, or providing cuts in a fractal element may be used to tune such systems. <IMAGE>

IPC: C08F110/10
Filed: 1996-11-15
Abstract: Improved processes have been developed for atom (or group) transfer radical polymerization (ATRP). In one improvement, the ATRP process involves polymerizing in the presence of a (partially) free radical-deactivating amount of the corresponding reduced or oxidized transition metal compound. In a further improvement, the ATRP process involves polymerizing in a homogeneous system or in the presence of a solubilized initiating/catalytic system. The present invention also concerns end-functional, site-specific functional and telechelic homopolymers and copolymers; block, random, graft, alternating and tapered (or "gradient") copolymers which may have certain properties or a certain novel structure; star, comb and "hyperbranched" polymers and copolymers; multi-functional hyperbranched, end-functional polymers; cross-linked polymers and gels; water-soluble polymers and hydrogels (e.g., a copolymer prepared by radical copolymerization of a water-soluble monomer and a divinyl monomer); and an ATRP process using water as a medium.
