Title: Dose setting limiter
Inventor: MOLLER CLAUS SCHMIDT
IPC: A61M5/31
Filed: 2000-09-04
Granted: 2008-12-30
Abstract: A limiting mechanism which prevents the setting of a dose, which exceeds the amount of liquid left in a cartridge of an injection device is disclosed. The injection device is the type where a dose is set by rotating a dose setting member relative to a driver and away from a fixed stop in the injection device. The dose setting member interfaces the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating back the dose setting member which during the backward rotation carries the driver with it. Rotating the driver causes the piston rod to move forward inside the cartridge and expel some of the liquid contained in the cartridge. The driver is provided with a track having a length which is related to the total amount of liquid in the cartridge and which track is engaged by a track follower coupled to the dose setting member to follow rotation of this dose setting member. Each time a dose is set and injected, the track follower moves further into the track. When the track follower reaches the end of the track the dose setting member cannot be rotated further, and a dose larger than the remaining liquid in the cartridge cannot be set.

Granted: 2009-05-19
Abstract: A process is described for the co-production of maleic anhydride and at least one C4 compound selected from butane-1,4-diol, .gamma.-butyrolactone, and tetrahydrofuran in which maleic anhydride is produced by partial oxidation of a hydrocarbon feedstock selected from C4 hydrocarbons and benzene to yield a vaporous reaction effluent stream comprising maleic anhydride, water, unconverted hydrocarbon feedstock, and carbon oxides. A part of the maleic anhydride present in the vaporous reaction effluent stream is condensed to form a crude maleic anhydride stream and leave a residual vaporous stream containing residual amounts of maleic anhydride. Further maleic anhydride is absorbed from the residual vaporous stream by absorption in an organic solvent, water or an aqueous solution. Maleic anhydride is then recovered from the loaded liquid absportion medium. Said at least one C4 compound is produced by hydrogenation of a C4+ hydrogenation feedstock selected from maleic anhydride, maleic acid, dialkyl maleates, and mixtures of two or more thereof. The process is characterised in that material of the crude maleic anhydride stream is used as the C4+ hydrogenation feedstock or is used to prepare the C4+  hydrogenation feedstock.

Patent CA-2403952-C (CA)
Inventor: VOIGT HEIKO
IPC: B22D15/02
Filed: 2001-03-09
Granted: 2009-05-26
Abstract: This invention relates to a method for uphill casting in sand molds with hig h- resin casting cores or especially casting cores containing binders, and with directed solidification of metallic castings that have at least one cavity. In particular, these are prototypes of engine blocks or cylinder heads, for example for internal combustion engines that are provide d with a cavity through which coolant water flows. To provide for low-turbulence flow of the liquid molten metal during the deaeration of the casting mold, the casting mold (1) with at least one feeder head (24) is connected through a casting system (22) to an infeed funnel (23), and the molten metal it contai ns is displaced by gravity through the casting system (22) into the casting mold (1), with the cavity (11') in the molten metal being subjected after the filling to reduced pressure that is greater than the pressure of the core gases formed in the core. This eliminates the hindrance to filling the mold from air pockets in the mold. At the same time, dense and pore-free, mechanically strong cast parts are produced by the method.

Title: Systems and methods for topical treatment with nitric oxide
Inventor: SEITZ WILLIAM A
IPC: A61K9/00
Filed: 2000-05-24
Granted: 2011-08-02
Abstract: A simple, biocompatible system and procedure for generating nitric oxide (NO) is described. A mixture of powdered sodium nitrite, ascorbic acid, and maleic acid (or another organic acid of adequate strength) immediately generates nitric oxide (NO) on treatment with water. To slow down the NO generation, one may prepare an ointment from a nonaqueous medium (petrolatum, VaselineTM) and the three powdered ingredients, which on being applied topically on the skin will release NO as water permeates through this medium; alternatively, one may convert the aqueous sodium nitrite solution into a gel with hydroxyethylcellulose (or other gel-forming compound) and combine this gel with another gel obtained from aqueous ascorbic and maleic acids with hydroxyethylcellulose for topical application (on intact skin, burns, intra-cavity, burns, intra-cavity, etc.). The two gels may be admixed immediately before use (possibly from a single container with separate chambers and dual nozzle, via pushing or squeezing the two gels through the nozzle), or may be applied in sandwich-like fashion (possibly as a transdermal patch) for further slowing down the delivery of NO.

Title: System and method for detecting cheque fraud
Inventor: DOUGLAS DONALD J
IPC: G06V30/10
Filed: 2002-12-05
Granted: 2008-10-14
Abstract: A system and method for detecting cheque fraud includes a cheque scanning module and a detection module. The cheque scanning module scans cheques and matches the encoded Magnetic Ink Character Recognition (MICR) data (i.e. serial number, Customer Account Number and amount) from the scanned digital electronic images with items in an issuance database which contains client provided cheque particulars. The detection module passes the cheque images through an optical character recognition (OCR) process to read what is written on the cheque and to match results against the issuance database. If the written information on the face of a cheque is unreadable or there is no match with the information in the issuance database, the detection module passes the cheque through a series of slower more precise OCR processes. Any cheques that are not successfully read and matched are highlighted as an "exception" and immediately forwarded to the client for further action.
