Title: Device for heating a drinkable liquid
Inventor: TIMM EBERHARD
IPC: A47J31/00
Filed: 1995-12-29
Abstract: The device for heating a drinkable liquid comprises a liquid-supply container (9) and an electrical heating element (11) disposed therein. The liquid-supply container (9) comprises a valve which is disposed at the bottom in the base (12) of the liquid-supply container (9). One sealing surface of the valve forms the edge of an opening (14) in the base (12). At the predetermined internal pressure of the container, owing to the outward curvature of the base (12), the valve does not open such that it is automatically reversible. The power delivery to the heating element (11) is designed such that it is interrupted when the pressure in the liquid-supply container (9) is substantially equal to atmospheric pressure. The device can be placed on a collecting tank for the liquid and is characterized in that the second sealing surface of the valve is a disk-like element (15) of resilient material which, in its unloaded state, is substantially conical with the cone tip directed towards the interior of the liquid supply container (9), the element (15) being held at this tip.
Patent CA-2212079-A1 (CA)
Inventor: SIMEONOFF GEORGE
IPC: E04H12/10
Filed: 1997-09-03
Abstract: At present date there are innumerable designes of O.W.S.J. (Open Web Steel Joist) used for suspended platforms in construction of buildings, also of late there are Deep"C" Chanells from galvanised steel sheets for use as joists, studs and rafters in the construction industry. The specific requirement of my "WSSS" is to fill the need of a steel wall stud for exteriour walls or fire walls, heavy enough to satisfy structural requirements but with minimal "thermal short" effect. Although it appears similar to an ordinary "OWSJ" or a "Ladder" its designe is very different. The "Stringers" or "Webs" here are wires usually 6mm diameter and maximum 8mm diameter, with no rigidity but sufficient tensile strngth, welded to the ouside and inside posts. Plese reffer to sketch#1 The main intention of my "WSSS" is to be used in constructing insulated concrete walls and light steel structures.

Title: Absorption process for rejection of reactor byproducts and recovery of monomers from waste gas streams in olefin polymerization processes
Inventor: STODGHILL ROBERT H
IPC: C08F2/34
Filed: 1996-02-26
Abstract: A process for recovering unreacted monomers and rejecting reactor byproduct from a polymerization reactor in an olefins polymerization process wherein reactor waste gas stream(s) comprising unreacted monomers, reactor byproduct and light components are treated in an absorption process to additionally recover the monomers. The absorption process comprises contacting the reactor waste gas stream(s) with an absorption solvent in an absorption zone to produce a gas stream comprising the light components, and a liquid stream comprising the absorption solvent, absorbed reactor byproduct and absorbed monomers. The liquid stream is fractionated in a distillation column to produce a distillation column bottoms stream that is the absorption solvent which is conveyed to the absorption zone, and an overhead stream comprising the monomers and reactor byproduct which is further fractionated in a splitter column to reject the reactor byproduct as a bottoms stream. The recovered monomers from the splitter overhead can be conveyed to the reactor. In a preferred embodiment, the absorption solvent consists essentially of components derived from the reactor waste gas stream(s) so that no external solvent is required.

Title: Reduction of adhesions using controlled delivery of active oxygen inhibitors
Inventor: BAKER KEITH
IPC: A61K9/14
Filed: 1996-03-20
Abstract: SOD and other active oxygen inhibitors are directly applied in combination with a barrier material at local sites of tissue injury to prevent or decrease formation of adhesions and undesirable profileration of cells. Preferred barrier materials are polymeric hydrogels providing controlled release of AOI which are directly applied to the afflicted tissue. Examples demonstrate the effects of SOD on pelvic adhesions in the rat when administered by intraperitoneal (IP.) bolus and by localized sustained release from a topically applied hydrogel system.

Patent CA-2218308-A1 (CA)
Title: Digital signature protocol
Inventor: VANSTONE SCOTT A
IPC: H04L9/32
Filed: 1997-10-10
Abstract: A digital signature protocol generates a signature component using a hash of an encrypted message. The component and encrypted message form a signature pair that is forwarded to a recipient. The encryption message is used to retrieve the encryption key at the recipient and authenticate information in the message. The signature pair may be applied to a data carrier as a bar code for use in mail delivery services. By utilizing a hash of the message, a reduced message length is achieved as individual signatures are not required for each component of the message.

Patent CA-2220887-A1 (CA)
Inventor: DAMASSE JEAN-MICHEL
IPC: B22D11/16
Filed: 1997-10-27
Abstract: A detection method of continuous casting between rolls of steel products comprises measuring continuously the roll separation strain (RSF) and a signal representative of the variations in this strain (RSF) generated as a function of time. The signal is used to act upon the roll separation to compensate for any untrue roundness of the rolls. During these measurements the signal is separated into different harmonic components and the resulting comparison of the harmonic components thus obtained with some reference harmonics is representative of the state of defects in the rolls. This state of defects in the rolls allows the definition of different rules for conducting the casting process as a function of the gravity of the roll defects measured.

Inventor: BROWN GREGORY PATRICK
IPC: C01F7/144
Filed: 1996-07-11
Abstract: A process for precipitating alumina trihydrate from a pregnant caustic liquor comprising supplying the pregnant caustic liquor (10) to a precipitation stage of a Bayer plant. The precipitation stage includes an agglomeration stage (A1, A2) and a growth stage (G1, G2... Glast). Precipitation of alumina trihydrate takes place in the precipitation stage to form a slurry of precipitated alumina trihydrate in caustic liquor. During the precipitation process, the slurry is diluted by addition of an aqueous stream (115). This dilutes the caustic concentration of the liquor in the slurry, which increases the driving force for precipitation, thereby increasing yields from the precipitation process. The dilution stream may be added to the slurry as a single stream or a plurality of streams.

Title: Methods for molding hinged starch-bound articles
Inventor: HODSON SIMON K
IPC: B29C33/36
Filed: 1997-06-10
Abstract: Method and systems for forming hinged starch-bound matrices. Starch-based compositions are molded between heated molds in order to form a cellular matrix and also to remove water from the starch-based compositions in order to form a binding matrix of solidified starch. The molding apparatus is configured to form one or more creases (230) within the hinge structure (200) in order to define one or more lines upon which the hinge will bend. The molding apparatus is also configured such that the region of the mold corresponding to the inner surface of the hinge area will transfer heat more slowly to the interior skin portion (224) of the inner hinge surface, resulting in reduced thickness of the skin of the inner hinge. This increases the collapsibility, or ability of the inner surface of the hinge to fold or buckle, during the bending action. This in turn reduces the bending radius of the hinge such that the hinging action exerts less strain on the outer surface of the hinge. The inner surface of the hinge may optionally by treated with glycerine or other polyol to soften the inner surface. The exterior skin portion (226) of the hinge may optionally be coated with an elastomeric material, such as polyvinyl alcohol, in order to strengthen the outer surface and reduce its tendency to fracture during the hinging action.
