Title: Methods for the diagnosis and prognosis of cancer
Inventor: GIORDANO ANTONIO
IPC: C12N15/11
Filed: 1997-04-03
Abstract: The invention provides diagnostic and prognostic methods which comprise determining the level of expression of the tumor suppressor gene pRb2/p130.  Because the relative level of pRb2/p130 expression correlates with the presence of cancer, tumor grade, and patient prognosis, these methods may be used to detect cancer, to make treatment decisions, to predict patient outcome, and to predict the risk of cancer in disease-free individuals. The invention further provides methods for the detection of mutations and polymorphisms in the pRb2/p130 gene, which may be used to characterize genetic events associated with tumor formation, to trace the parental origin of mutations, to identify carriers of germline mutations, and to identify individuals with a predisposition to cancer.

Abstract: A versatile drawer organizer structure (100) for segregating a plurality of items. The structure (100) includes a main compartment (102) and two adjustable side compartments (104) located on each side of the main compartment (102). Each of the side compartments (104) can slide toward the main compartment (102) or away from the main compartment (102) thus decreasing and increasing the size of the side compartments (104) and decreasing and increasing the overall width of the structure (100) so that the structure precisely fits within the inside width of the drawer (10). The overall width of the structure (100) can be adjusted without cutting of the material making up the structure and without making any permanent alterations to the structure. Thus, the structure (100) can be easily sized to precisely fit the inside width of a large number of different drawers and many other enclosed spaces.

Title: Method and apparatus for performing data rate determination
Inventor: SAINTS KEITH W
IPC: H04W24/08
Filed: 1997-10-27
Abstract: A system and method for determining the transmission rate of a data signal at a receiver of a variable rate communications system. A vocoder at a transmitter encodes a frame of data into symbols according to one of a set of discrete data rates. When the data rate is lower than the maximum, each symbol is repeated a number of times as required to achieve a constant number of symbols in each frame. The data signal is transmitted at a power proportional to the data rate of the frame. A reference signal is also transmitted. The reference signal is transmitted at a constant power. Further, the data signal has the same carrier frequency as a reference signal so that they exhibit the same fading characteristics as they are transmitted through the channel. At a receiver, the power of the reference signal is measured by the pilot measurement element (36) and the power of the data signal is measured by the traffic power measurement element (38). The rate processor (46) dtermines the ratio of the power of the data signal to the power of the reference signal, and the measured ratio is compared with a predetermined ratio of the power of a maximum rate data signal to the power of the reference signal. The result of the comparison will indicate the encoded data rate of the received frame of data. The decoder (40) then uses the rate indicated by the comparison to properly decode the frame of data. A vocoder at the receiver further processes the data for interface with the user.

Abstract: Apparatus and a process for providing oxygen and hydrogen at a desired minimum pressure from an electrolyser comprising an anolyte solution having an anolyte liquid level; a catholyte solution having a catholyte liquid level; oxygen generated at an oxygen pressure above said anolyte; hydrogen generated at a hydrogen pressure above said catholyte for passage through hydrogen outlet means; the method comprising raising the oxygen pressure above the anolyte to effect a positive liquid level pressure differential between said catholyte level and said anolyte level to a pre-selected value to effect closure of said hydrogen outlet means and an increase in the hydrogen pressure to a value to effect opening of said hydrogen outlet means to provide hydrogen at said desired minimum pressure. The hydrogen are provided on demand at a readily available pressure suitable for use, such as in the case of hydrogen in metal hydride production or supply to a compressor for subsequent higher pressure utility; and oxygen for breathing assistance and santization purposes. The pressure differential across the cell membrane is low or negligible, notwithstanding the hydrogen and oxygen product pressure.

Title: Slide bar for a snowmobile track suspension system
Inventor: GULLA JOSEPH M
IPC: B62D55/24
Filed: 1999-05-25
Abstract: A slide bar for snowmobiles has sinusoidal grooves running lengthwise on the sliding surface that open at the aft end of the slide bar for drainage. The sinusoidal grooves retain packed snow accumulated during operation over snow-covered terrain, until the packed snow absorbs sufficient heat to soften and pass through the recurving path of the grooves. The retention characteristic of the sinusoial grooves for holding packed snow provides extended lubrication and cooling to the slide bar and track when the snowmobile leaves snow covered terrain to cross intermittent stretches of bare ground
Patent CA-2273169-A1 (CA)
Title: Variable length decoder and decoding method
Inventor: CHUJOH TAKESHI
IPC: H04N19/61
Filed: 1998-10-02
Abstract: Encoded data using variable length code words which can be decoded in two ways are first inputted to a forward decoder (123) and decoded forward by the decoder (123). When an error is found in the encoded data during the forward decoding, a reverse decoder (126) starts reverse decoding. A decode value determining unit (125) determines a decodc value by utilizing the results of decoding in both the forward and reverse directions and the positions at which bit errors and syntax errors are found in the encoded data during the forward and reverse decodings.

Abstract: The present invention includes methods, an apparatus and a system in which reclosable bags and components thereof are formed. The reclosable bags (2001) are made from base web material that has transversely applied fastener tape segments thereon. The web material is used in a vertical form, fill and seal bag forming method. The method includes the steps of supplying a continuous strip of tape, having male and female fasteners profiler across the web for sealing thereon. In one embodiment a continuous strip of barrier material, and a continuous strip of fastener having first and second interlocked fastener profile strips are positioned on the continuous strip of tape; and secured thereon, the barrier tape is folded to obtain a fold and two opposing barrier tape fastener strip connecting portions; and, the fold is slit to form two separate continuous strips of barrier material strips and two continuous strips of tape. In another embodiment a coating is applied to the tape itself to prevent sealing of the folded slit tape to itself. The resulting tape and fastener are cut (220) and portioned properly on the web by the unique vacuum belt system of the present invention and by the interconnected tape drive, web drive and the connection to the form fill seal machine.

Filed: 1997-11-20
Abstract: The present invention relates to an absorbent article and preferably a diaper or incontinent device hav-ing perfume zones disposed on the backsheet outer surface or on a back-ing member attached to the backsheet outer surface. The perfume zones   generally comprise a binder having release agents of one or more types dispersed therethrough.
