Title: Stented Bioprosthetic Heart Valve
Inventor: EBERHARDT CAROL E
IPC: A61F2/24
Filed: 1995-04-21
Abstract: A supported bioprosthetic heart valve is pro-vided. The valve includes a stent (16) and a biological valve member (18). The stent has an annular frame de-fined by a support rail. The support rail (36) is formed to define a triad of axially-projecting circumferentially-spaced commissure posts (38, 40, 42), each post hav-ing an inverted U-shaped configurationn and a pair of legs. Each of the pair of legs has an upper end and a lower end. The lower end of each leg merges smoothly with the lower end of a leg of an adjacent commis-sure post. A sleeve (48) having an inflow end (50) and an outflow end is fitted around the annular frame. The biological valve member is defined by a tubular wall (20) and three leaflets, the three leaflets being attached to the tubular wall and axially converging along three commissures. The biological valve mem-ber has a shape which fits the contour of the support rail and is disposed under the support rail. The bio-logical valve member is sutured to the support rail and the outflow end of the sleeve. The bioprosthetic valve member also includes a suturing cuff (46) which is not rigidly attached to the support rail allowing the valve to expand and contract in the lateral direction. The suturing cuff is formed by wrapping the inflow end of the sleeve around a ring-shaped cushion and suturing the sleeve to itself encapsulating thus the ring-shaped cushion. An inflow support ring (47) may also be pro-vided within the suturing cuff for added lateral support.

Abstract: A bill pay system (figure 4) wherein participating consumers (12) pay bills (30) to participating billers (14) through a payment network (102) operating according to preset rules (104). The participating consumers (12) receive bills (3) from participating billers (14) (paper/mail bills, e-mail notices, implied bills for automatic debts) which indicate an amount, and a unique biller identification number (120). To authorize a remittance, a consumer (12) transmits (2) to its participating bank (16) a bill pay order (122) indicating a payment date, a payment amount, the consumer's account number with the biller (14) 2 source of funds (232) and the biller's (14) biller identification number, either directly or by reference to static data containing those data elements. Bank C (16) then submits a payment message (124) to a payment network (102), and the payment network (102), which assigns the biller reference numbers, forwards (268) the payment message to the biller's bank (18). For settlement, the consumer's bank (16) debits the consumer's (12) account and is obligated to a net position with the payment network (102); likewise, the biller's bank (18) receives a net position from the payment network (102) and credits the biller's bank account (268). If the consumer's bank (16) agrees to send non-reversible payment messages (124), the consumer's bank (16) does not submit the transaction until funds are good unless the consumer's bank (16) is willing to take the risk of loss if funds are not good, in the case of a guaranteed payment network (102).

Title: Continuously variable transmission capable of torque control
Inventor: FELLOWS THOMAS GEORGE
IPC: F16H61/00
Filed: 1994-12-09
Abstract: A continuously-variable-ratio transmission ("CVT") of the band-and-sheave type capable of "torque control", so hat what the operator demands, by movement of the accelerator pedal or other control member, is a particular driving torque applied to the ratio-varying component ("variator").  A connection (21, 22) between at least one of the variator sheaves (3, 4) and its shaft (5) is torque-sensitive, so that torque at that sheave generates an axial force which is a function of the magnitude and direction of the torque to which the sheave is subjected.  Examples are described in which the operating axial load, applied to the variator pulley units, comprises two parts -a first part to maintain  traction between sheaves and band, and a second part related to the applied torque- and a variator using more than one band.

Title: Method for detecting small molecules in liquids
Inventor: BAKER MARK D
IPC: G01N30/00
Filed: 1996-06-19
Abstract: A method for detecting organic molecules such as benzene, xylene, ethylbenzene and toluene present in trace quantities in aqueous solutions is provided. The method uses a zeolite having a multiple cage structure, specifically cages of two different volumes. The zeolite is chosen so that the organic molecules are able to access the zeolite on the basis of size.   The small cages contain electroactive ions therein and the larger cages contain electroinactive counter cations therein. An aqueous liquid sample to be tested for small molecules is flowed into contact with the zeolite whereby at least some of the electroactive ions in the small cages are released into the aqueous liquid sample by small molecules entering the larger cages and coupling with the electroactive ions in the smaller cages and exiting the zeolite. Thereafter the liquid sample is flowed into contact with an electrode downstream of the zeolite and a potential is applied to the electrode with respect to a counter-electrode effective to cause an electrochemical reaction of the electroactive ions.
Patent CA-2180047-A1 (CA)
Inventor: COMEAU LAURIER E
IPC: E21B29/06
Filed: 1996-06-27
Abstract: A joint of tubular casing with a pre-formed window in its sidewall, has a tubular sleeve fixedly attached to the interior of the tubular casing by a plurality of shearable set screws. The exterior surface of the sleeve is sealed to the interior surface of the tubular casing on opposing sides of the window. The window is filled with a fluid and then the window is covered with one or more layers of a composite material such as fiberglass. In use, the joint of tubular casing is run down to the depth of interest in an earth borehole, and then the window is oriented with respect to the formation of interest at the depth. The joint of tubular casing is then cemented in place, after which the tubular sleeve is retrieved by the use of a fishing tool causing the set screws to shear upon the upward movement of the fishing tool. After the interior sleeve is retrieved, a whipstock is lowered into the cased borehole, until it is oriented and anchored therein. The assembly automatically fixes the axial and circumferential orientation of the whipstock within a surrounding casing joint and holds the assembly in place. Alignment and fixing of the whipstock ensures proper engagement and orientation of a drill bit with an access window formed in the casing wall. The assembly employs multiple spring loaded latches which register with and extend into corresponding receiving recesses formed on the inner surface of the casing joint. The recesses, which are spaced circumferentially around the interior of the casing joint, contain differing profiles which uniquely mate with corresponding profiles on the latches. The relative position of the latches with the recesses determines the amount of radial latch movement providing keyless anchoring and orientation of the assembly within the casing. Setting is positively confirmed with a simple rotational force on the setting string. The spring loaded latches release from anchored, oriented position in response to an upward axial force exerted by the drill string to provide a straight pull release of the assembly. Confirmation of correct axial location and proper circumferential orientation may be made by surface monitoring of the setting string weight and turning torque.

Title: Enhancing host immunity against viral infections
Inventor: BARAL EDWARD
IPC: A61K31/135
Filed: 1996-06-28
Abstract: Cell mediated immunity against persistent viral infection in a host is potentiated by administering to the host an effective amount of at least one antiestrogen capable of enhancing cytotoxic T lymphocytes in the host, such as a triphenylethylene tamoxifen, particularly tamoxifen or toremifene.  This administration leads to the elimination of all infected cells and to the complete clearance of virus and virus induced tumor cells from the body, leaving protective cell mediated immunity.  This therapy requires MHC restricted virus specific CTLs which then will kill virus infected very specifically, which may be initially present or formed in vivo or in vitro. The effect of the antiestrogen may be enhanced by the use of interferons optionally with indomethacin.

Patent CA-2208195-A1 (CA)
Inventor: LANG STEPHEN J
IPC: B65D6/02
Filed: 1997-06-18
Abstract: A packaging device includes upper and lower container portions that support respective frames that, in turn, support respective support films.  The frames and the container portions are configured such that the act of installing the frames in the container portions automatically increases tension in the films.  This can be accomplished by rotating opposed portions of the frames in opposite directions, by displacing the film out of the plane in which it is originally supported by the frame, or by displacing opposed portions of the frame away from one another.  The film of the lower container portion is recessed with respect to a peripheral lip of the lower container portion, while the film of the upper container portion protrudes beyond the peripheral lip of the upper container portion.  In this way objects are prevented from rolling out of the lower container portion, yet the films are brought into face-to-face contact when the packaging device is closed.
