IPC: A61B10/00
Filed: 1995-09-22
Abstract: Endoscopic biopsy forceps jaws (14) having an outer edge (33, 333, 433, 633, 833) which may be generally U-shaped, circular, or oblate circular are disclosed with a number of teeth (40-51, 240-250, 440-454, 540-533, 740-753) which extend along at least a portion of the outer edge where the peaks of the teeth are located upward and inward from the outer edge. In one embodiment, each tooth is defined by a substantially triangular inner surface (T), a substantially quadrilateral base (L1-L4), and a surface which extends outward and downward from the vertex of the triangular surface to the outer edge of the jaw. Valleys (40V-51V, 240V-250V, 440V-454V) between the teeth have two inclined surfaces which intersect along a line which extends inward and downward from the outer edge of the jaw. In a second embodiment, the peak of each tooth is defined by the vertex of a pyramid having four faces (T1-T4) and valleys between these teeth have three substantially flat surfaces (V1-V3) which intersect at a vertex (V4) which lies downward and inward from the outer edge of the jaw. Alternate embodiments of both the first and second embodiment of the jaws include providing a lip (133L, 333L, 833L) around the outer portion of the outer edge so that the teeth and valleys are spaced farther in from the outer surface of the jaw cup.

Title: Liquid alkylated diphenylamine antioxidant
Inventor: LAI JOHN T
IPC: C10M133/12
Filed: 1997-05-29
Abstract: A process for monoalkylating diphenylamine using a clay catalyst is disclosed which results in a reaction product having substantial amounts of desirable monoalkylated diphenylamine and minimal amounts of less desirable disubstituted diphenylamine and unsubstituted diphenylamine. The disclosed process uses clay catalysts which favor monoalkylation over dialkylation and specific conditions such as reaction temperature, mole ratios of alkylating olefin to diphenylamine, reaction times, and catalyst amounts. Preferred olefins are diisobutylene and linear alpha olefins having from 6 or 8 to 18 carbon atoms. When more than 1 wt.% residual unreacted diphenylamine is present it may be converted to alkylated diphenylamine by reacting with styrene, alpha-methylstyrene or isobutylene.

Patent CA-2209741-A1 (CA)
Title: Anatomical pillow and mattress
Inventor: SANNA TONINO
IPC: A47G9/00
Filed: 1997-07-14
Abstract: This invention relates to a pillow (1) and a mattress (6) the anatomical shape and rigidity of which help to combat pathological lordosis of the forward convex curvature particular to the cervical region and spondylitis in the dorsal region of the vertical column. The pillow (1) consists of two rounded lobes (2) and (3) with an anatomical shape for resting the head when the body is lying down in an antero-posterior position. The mattress is rectangular in shape and its anatomical shape and rigidity allow for perfect posture of the vertebral column in a dorsal or lateral recumbent position, thus guaranteeing decompression of the vertebral discs, which is an essential factor for combatingspondylitis. Both are essentially made of a latex-type polyurethane foam the rigidity of which is designed not to affect or alter the pressure of mainly the cervical and dorsal blood vessels, and inside they contain a suitable number of clay discs (4) in pre-defined positions, which are connected to the outside by means of three vertical holes (5). These discs create absorbent and healing conditions owing to the properties of the clay.

Patent CA-2215967-A1 (CA)
Inventor: IVANOV EVGENIY VLADIMIROVICH
IPC: G01N21/35
Filed: 1996-03-20
Abstract: An optical gas analyzer includes optical, mechanical and electronic systems.  The optical system includes a collimator, a light filter, a modulated interference polarization filter (IPF), and a photo detector. The modulated IPF has two polarizers, crossed or parallel to each other, with an optical modulator and a birefringent plate mounted between them. The birefringent plate has a variable thickness which is mechanically driven and controlled by the electronic system via the electro-mechanical driver. The photo detector has its output connected to the electronic system and is placed after IPF. The gas analyzer has the advantage of allowing the minimum detectable limit of the concentration of measured gas to be decreased by greatly reducing the influence of parasitic modulation. Parasitic modulation is induced by the optical modulator into the optical and electronic units of the gas analyzer and affects the output signal. However, synchronous modulation of the modulated IPF cancels the parasitic effect in the final output, based upon the difference of two such measurements.

Patent CA-2229349-A1 (CA)
Inventor: JAVITT JOEL I
IPC: H04W84/10
Filed: 1998-02-12
Abstract: Free-space, line of-sight, electro-magnetic communication (i.e., via light or microwaves) is employed to provide a wide range of communication services to geographically scattered users. A relay point or end point is typically associat ed with each user. Each relay point receives and retransmits information via line-of-sight communication. The end points are also receivers and transmitters of information via line-of-sight communication. Although spaced from one another, the relay and end points are close enough to one another to communicate via line-of-sight links. Hard-wir ed connections to the users are therefore unnecessary. Broadcast radio frequency communication capability may be provided as a backup for maintaining at least so me service in the event of line-of-sight communication failure or interruption. Thi s radio capability may additionally be used to provide cellular communication service to small cells associated with the relay and end points.
