Title: Helical cutting insert with offset cutting edges
Inventor: DEROCHE KENNETH G
IPC: B23C5/10
Filed: 1996-02-05
Abstract: A cutting insert (20) for use in a rotary milling tool (10) is provided. The cutting insert (20) includes an insert body including a bottom face (22), a top face (24) and a side face (26). A stepped cutting edge (20) is formed at the intersection of the top face (24) and the side face (26) for engaging a workpiece and removing a chip from it. The stepped cutting edge includes at least two offset edge portions (30a-c) which produce distinct, transversely-spaced chip segments during the cutting operation. The offset edge portions (30a-c) are connected by transition edge portions (30d-e) which are disposed at an obtuse angle with respect to the offset edge portions. The angle of the transition edge portions tends to spread the individual chip segments apart during the machining operation to effect a thinning of the chip between the individual chip segments. The entire cutting edge is helically curved so that the cutting edge lies on the surface of a circumscribing cylinder defined by the rotation of the cutting edge about the axis of the milling cutter.

Title: Digital signal processing apparatus for frequency demultiplexing or multiplexing
Inventor: WISHART ALEXANDER WALKER
IPC: H04J1/05
Filed: 1997-09-08
Abstract: The present invention is directed to a digital signal processing apparatus for frequency demultiplexing a wideband channel. The apparatus converts the data stream into parallel branches by means of a serial-to-parallel converter. The demultiplexing operation consists of a low pass and high pass fine filtering stage and a coarse filtering stage and is split among processors across the parallel branches. Wideband signals can be processed without expensive processors because of the slower rate in the parallel channels. The invention may also be used for the inverse function of multiplexing.
Patent CA-2215855-A1 (CA)
Inventor: GARVER THEODORE M
IPC: D21C9/16
Filed: 1997-09-18
Abstract: The brightening activation process requires chemical pretreatment using Na2S before the bleaching or brightening of wood pulps with hydrogen peroxide. The pulp is mixed with 1-3% Na2S and heated for 30-90 minutes at ~60°C at medium consistency. The resulting pulp is acidified and washed, if possible, before pressing to highconsistency (20-30 %). The pre-bleached pulp is then bleached in the standard way with alkaline hydrogen peroxide except higher temperatures and pH values may be used to accelerate the bleaching response. Under identical conditions during the peroxide bleaching stage the Na2S pretreatment results in a 25-35% increase in efficiency. The pretreatment process allows adjustment of the peroxide bleaching conditions to higher pH, higher peroxide concentration and higher temperatures with substantial improvement to the ultimate brightness and low loss of residual peroxide. Pulp brightness of 85% ISO for spruce and 89% ISO for aspen can be attained using this method and peroxide concentrations less than 7.5% on pulp.

Abstract: The lamellarin compounds disclosed herein have been found to be inhibitors of MDR, i.e., acquired multidrug resistance, which has become a major problem in the treatment of various cancers. The lamellarin compounds disclosed herein have also been found to be cytotoxic to MDR cells. MDR is believed to be associated with certain alterations in tumor cells, including an over-expression of a certain high molecular weight membrane glycoprotein and a decrease in the ability of the tumor cell to accumulate and retain chemotherapeutic agents. The present invention is thus directed to methods of treating MDR-type tumors with an effective anti-MDR amount (either inhibitory or cytotoxic) of one or more lamellarin compounds, which compounds have been found to be effective antitumoral agents against MDR  cells.

Title: Tubular refrigerant check valve with indented outer housing portion
Inventor: JAKOBS DIANE M
IPC: F16K15/04
Filed: 1998-01-28
Abstract: A check valve connectable in a refrigerant line is economically fabricated from only three parts  -  (1)  a copper tubing body connectable in the refrigerant line, (2) a nonmetallic shutoff ball, and (3) an annular valve seat member having a conically tapered seating surface on one of its ends.  The seat member is coaxially received within a first end of a longitudinally central portion of the tubing positioned between spun-down opposite end portions thereof, with the seating surface end of the seat member facing the second end of the central tubing portion,  and the ball being received in the central tubing portion for axial movement  into  and out  of  sealing  engagement  with the seating surface.  Three circumferentially spaced, axially elongated side wall indentations are formed in the central tubing portion  .   The indentations have  (1)  first end portions which, with the first end of the central tubing portion, axially locks the seat member within the central tubing portion, (2) second end portions that combinatively form an axial stop for the ball, and (3) main body portions that combinatively form within the central tubing portion a track structure that axially guides the ball between its closed position against the seating surface and its open position against the axial stop.  When the ball is in its open position against the axial stop,  refrigerant flows through the interior of the valve seating member and then around  the  ball  via  circumferentially  spaced,  axially extending fluid bypass passages positioned between the tubing side wall indentations.
