Title: Anti-reflux ureteral stent
Inventor: MESROBIAN HRAIR-GEORGE O
IPC: A61F2/04
Filed: 1997-05-15
Abstract: Ureteral stems are tubes which are placed in the ureter between the bladder and kidney to maintain patency when otherwise due to stone burden, invasive tumor, scarring, or whenever the ureter has become obstructed in order to provide drainage of urine from the kidney to the bladder. In the past, stems of this nature are open ended tubes and may allow for the reflux of urine back into the kidney when there is sufficient buildup of pressure within the bladder. Since urine is generally considered to be sterile when within the body, this is generally not a problem.      However, if the patient has a bladder infection and/or pyrogens are present, then urine refluxed into the ureter and kidney may result in the development of sepsis in the patient and cause serious illness and even death. The stent of the present invention has a very specific design and avoids this problem by providing a stent having a closed section, i.e., the bladder end section does not contain any fluid passageways and also comprises a means for retaining the stent within the bladder after implantation.
Patent CA-2207952-A1 (CA)
Inventor: COLLINGE JOHN
IPC: C12Q1/68
Filed: 1995-12-22
Abstract: A method of automatically sequencing DNA comprises repeatedly determining the next base in the sequence as a function not only of a physical measurement made at that position, but also as a function of previously-determined near by bases in the same sequence. Typically, a computer algorithm is used which predicts the value of the expected measurement at a given position based upon a knowledge of the bases in previous and/or subsequent positions. The predicted measurment is then compared with the actual measurement, and the base chosen at that position is the base which minimises the accumulated error measure for the entire sequence. The preferred algorithm, which may be parallel or sequential, preferably includes physical modelling of the replication effect and of the fluorescence effect.

Title: Arrangement at self expanding booms
Inventor: BERG PER OLOF
IPC: E02B15/06
Filed: 1996-03-05
Abstract: The invention relates to a device of a valve mechanism for self-expanding booms. The mechanism is preferably a mechanical expansion device that folds out the boom so that air flows into the boom to fill the boom. When the boom is folded, the air is pressed out of the boom. A novel feature is an automatic control mechanism that is adapted to permit an inflow of air into the boom when the boom is expanded and to permit an outflow of air when the boom is collapsed, rolled up and stored. The control mechanism is affected by the relative position between the valve mechanism and other parts of the boom when the boom is in the expanded or collapsed position.

Title: Method and device for regenerating tin-plating solutions
Inventor: REITER ULRICH
IPC: C23C18/16
Filed: 1998-04-30
Abstract: The invention relates to a method and a device for regenerating exhausted tin-plating solutions which contain tin and copper ions, free complexing agent and complexing agent bound to the copper ions, as well as expended and unexpended reducing agent.  By means of a suitable rinsing technique, the rinse water of the tin-plating process is concentrated to a 10 to 15 percent dilution of the process solution. The regenerating solution thus produced is fed to an electrolytic cell. The electrolytic cell comprises a cathode chamber, a middle chamber and an anode chamber. The cathode chamber is separated from the middle chamber by an anion-exchange membrane and the anode chamber is separated from the middle chamber by a cation-exchange membrane. The regenerating solution is initially provided in the cathode chamber. Here, the interfering copper component is cathodically deposited.  After an appropriate residence time, the regenerating solution, depleted of copper, is transferred by pumping into the middle chamber where tin enrichment is effected by tin ions diffused from the anode chamber through the cation-exchange membrane. The regenerated solution is subsequently fed back into the tin-plating process.

Title: Apparatus for controlling an ozone generator
Inventor: SHINAGAWA MISATO
IPC: G05B23/02
Filed: 1998-06-09
Abstract: The invention provides an ozone generator controlling apparatus capable of controlling an ozone generator so that when a discharge breakdown occurs in some discharge element, the operation of generating ozone can be continued without imposing a bad influence on the remaining normal discharge elements. When an anomaly occurs in one of or a plurality of discharge elements during the operation of generating ozone, the anomaly is detected by an anomaly detection means. In response to the detection of the anomaly, first output control means reduces the output of an AC power supply circuit to a sufficiently low level so that after the discharge element having the anomaly is isolated from the circuit the operation of generating ozone can be continued with the remaining normal discharge elements without interruption and without causing the normal discharge elements to encounter an overload current thus preventing them from being broken one after another. The discharge element having the anomaly may be isolated using nondestructive current cut-off means such as a high-voltage relay. In this case, the current cut-off means can be used for a very long time without having to replace when a breakdown occurs in some discharge element, unlike the case where a fuse is used as the current cut-off means.      When an anomaly occurs in some discharge element, instead of immediately isolating it from the circuit, the output of the AC     power supply circuit may be reduced using second output control means until the current detected by the current detection means becomes lower than the predetermined upper allowable limit. This makes it possible to continue the operation of generating ozone without isolating the discharge element having the anomaly.

Abstract: A method and apparatus for making aluminum alloy sheet product with improved paintbake response during automotive paintbake cycles, resistance to natural aging and better formability includes rapidly heating the aluminum alloy sheet product between a solution heat treating (5)/quenching operation (1) and a sheet coiling operation (13). Performing the rapid heating at this stage in the sheet manufacture minimizes the adverse effect of early natural aging (dwell time) on the paintbake response of these types of aluminum sheet alloy products. According to the invention, this dwell time is minimized by the application of a rapid heating step (7) immediately following quenching from the solution heat treatment. After the aluminum sheet product has been rapidly heated, it is immediately coiled and cools under ambient conditions in coil form (13), this ambient cooling providing a pre-aging treatment which contributes to the improved performance of the sheet product in paintbake response, improved formability and natural aging resistance.
