Patent CA-2009124-C (CA)
Inventor: LEE KYU H
IPC: A61M1/02
Filed: 1990-02-01
Granted: 1999-10-05
Abstract: A multicomponent fluid separation and irradiation system is described containing a centrifuge drum and a source of radiant energy located within the drum. In a first embodiment a disposable rigid separation/irradiation chamber is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source. Whole blood is supplied to the chamber through a dynamic seal located at the center of the chamber. As the chamber is rotated, blood is separated so that energy from the source passes through the inner wall of the chamber and the separated plasma layer to irradiate the buffy coat layer. In a second embodiment, one or both of the walls of the outer compartment of the chamber are flexible so that the chamber will expand as blood is pumped in and will collapse as blood is pumped out.

Title: Method for adaptively sharpening electronic images
Inventor: SONG WOO-JIN
IPC: H04N5/21
Filed: 1990-04-03
Granted: 2000-12-12
Abstract: Method and apparatus for sharpening edges and details of a digital image without amplifying noise in the digital image provide an output image which is the sum of the input image and its adaptively-amplified high frequency components, which adaptively amplified high frequency components are obtained by subtracting a low-pass filtered image from the input image. An adaptive amplification factor for the high frequency components is determined as a function of a variance of the pixel values surrounding a pixel and the noise power of the imaging system.

Granted: 1994-08-16
Abstract: A spring interior (21) comprising a plurality of longitudinally extending bands (22) of springs disposed side by side and connected together by helical lacing wires (23) in the top (25) and bottom (26) faces of the bands. Each band of springs (22) comprises a single length of wire formed into a plurality of substantially vertical coils (31) of springs interconnected by interconnecting segments (35, 36) of wire located alternately in the top and bottom faces of the bands. Each interconnecting segment (35, 36) comprises a longitudinally extending bridging portion (37), a pair of transversely extending end portions (38), and a transversely extending support structure (40). The corners (38a, 38b) defined by the intersections between the bridging portions (37) and the end portions (38) of the interconnecting segments are radiused by radii of differing dimension so as to colinearly align the bridging portions of each band of springs. Misalignment of the bridging portions of the bands of springs had heretofore reduced the durability of the spring interior (22).

Filed: 1992-04-13
Granted: 2004-02-10
Abstract: A metallic hose coupling assembly provides an improved coupling insert for flexible elastomeric hose. The insert contains a series of external barbs defined by repeating asymmetrical, axially inversely oriented pairs of frustoconical segments spaced apart by and contiguous with cylindrical segments positioned therebetween. each mated pair of frustoconical segments interfaces with a cylindrical segment in a manner which defines rounded interface edges having radii which fall within a range of 15 to 25 thousandths of an inch.

Granted: 1999-06-22
Abstract: An A/D converter 1 converts analog modulation signals, such as video signals and audio signals, into digital modulation signals.  A center frequency data setting circuit 6 outputs center frequency data for setting the center frequency of an FM wave.  An operation unit 5 outputs such addition data, on the basis of the center frequency data and average frequency data from a counter circuit 4, as will make the average frequency of the FM wave substantially identical with the center frequency that has been set.  An adder 2 adds the digital modulation signals and the addition data, and outputs addition digital signals.  A DDS 3 accumulates an addition digital signal in every sampling period supplied from a reference oscillator 7.  In the ROM 32 of the DDS 3 are stored sine wave data and the ROM 32, having the accumulated signals as its address input, outputs the sine wave data.          The counter circuit 4 figures out the average frequency of the FM wave from the DDS 3, and supplies average frequency data to the operation unit 5.

Patent CA-2098860-C (CA)
Inventor: MCHARDY JOHN
IPC: G01F23/00
Filed: 1993-06-21
Granted: 1997-03-25
Abstract: Precise information about the position of a liquid-liquid interface (28, 32) is often important for the control and automation of molten metal refining processes.   For example, in an electrolytic process for removing magnesium from molten aluminum, knowledge of the vertical position of an interface (32) between the electrolyte and the magnesium and an interface (28) between the electrolyte and the aluminum facilitates the automatic removal of the purified metals. Differences in surface tension in the fluid layers of a molten electrolytic  salt  (30)  and  a  molten metal  (29)  produce different pressures as bubbles (57) evolved from vertically displaced tips (52) of tubes (34, 36) press against the liquid layers on either side of their interfaces (28, 32).  These different pressures are detected by a differential pressure transducer  (42)  to  limit  the  amount of  purified molten aluminum from molten aluminum-magnesium scrap, when drawn through a port (26) in a reaction furnace (10) without risk of also  contaminating  the  purified  aluminum  with  the electrolyte (30) above the interface.

Granted: 1999-05-11
Abstract: A tarpaulin covering system for protecting a pile of material having an array of folded tubular vents connected to a tarpaulin to assist a weighting system on the tarpaulin in the prevention of aerodynamic lift.  The vents remain in a folded state when the air pressure between the tarpaulin and the pile of material is minimal.          During a period of increased air pressure, the vents in the area of increased air pressure open allowing for the escape of the entrapped air.  The venting system prevents a protective tarpaulin from being lifted off the surface of the material pile which may cause damage to the tarpaulin resulting in an decrease in the overall integrity of the protective tarpaulin system.
