Title: Method for separating trioxane from a mixture containing trioxane, formaldehyde and water
Inventor: GRUETZNER THOMAS
IPC: B01D3/36
Filed: 2004-12-21
Abstract: The invention relates to a method for separating trioxane from a mixture containing formaldehyde, trioxane and water. According to said method: the mixture (1) is distilled in a first distillation stage (7) at a pressure of between 0.1 and 2 bar to obtain a stream (8) containing formaldehyde and a stream (9) containing predominantly trioxane, in addition to water and formaldehyde; the stream (9) is mixed with a recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde to form a stream (10) containing predominantly trioxane, in addition to water and formaldehyde;  the stream (10) is then distilled in a second distillation stage (14) at a pressure of between 0.2 and 10 bar, optionally after the separation of low-boilers from the stream (9) or (10) in an additional distillation stage (11).  The pressure in the second distillation stage (14) is at least 0.1 bar higher than the pressure in the first distillation stage (7). Said distillation produces a stream (15) consisting of trioxane and a stream (16) containing predominantly trioxane, in addition to water and formaldehyde. The stream (16) is then distilled in a third distillation stage (17) at a pressure of between 0.1 and 4 bar, to obtain a stream (18) containing predominantly water, in addition to formaldehyde and the recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde. The resultant stream (18) is optionally distilled in a fourth distillation stage (20), to obtain a stream (21) containing predominantly water and a stream (22) containing predominantly formaldehyde.

Patent CA-2560181-A1 (CA)
Inventor: GREBE MAIK
IPC: B29C35/08
Filed: 2005-01-27
Abstract: The invention relates to a method and device for joining material in order to produce three-dimensional objects (7) by means of selective heating effected by a laser (5) having a wavelength ranging from 100 to 3,000 nm. To this end, the beam spot can be focussed or unfocussed or even two-dimensional like when using a diode laser during which the bars can be arranged in stacks. The selectivity of the melting on is achieved by applying an absorber to specified partial areas of a layer made of a powdery substrate (8), and by subsequently heating the absorber by means of laser radiation having a wavelength ranging from 100 to 3,000 nm. The heated absorber releases the energy present inside to its powdery substrate surrounding it whereby the substrate is melted on and, after cooling, they are tightly joined to one another. The method is distinctly more versatile, more economical and faster than conventional laser sintering.

Title: Method for sending location-based messages to mobile users
Inventor: DAVIS SCOTT B
IPC: H04W4/02
Filed: 2005-03-21
Abstract: A system and procedure for posting and receiving location-based messages in a wireless communication based network (10). The system allows messages to be posted to specified users and to be associated with a particular location (X1) for which the message is pertinent. The messages can be left when a user in a first vehicle (26a) passes a particular location (X1), or the user can specify the location (X1) for the message even if not present at that location (X1).  The messages can then be displayed at a user interface of the recipient vehicle (26b) either when the recipient nears that location (X1), or they can be reviewed in advance. Such location-based messages can be left either for another user or for the same user that is posting the method. The posted and received messages can be textual, audio, video, or pictorial messages and may be superimposed on computerized maps to make association between the message and the location more meaningful. Regardless, the disclosed system and methods allow messages to be associated with particular locations of interest.

Title: Conversion of calls from an ad hoc communication network
Inventor: NEWELL MICHAEL A
IPC: H04B1/38
Filed: 2005-03-21
Abstract: An improved system and procedure for allowing participants within a group conversation on a wireless communication network (10) to at least temporarily break away from a group conversation (90) and hold a side bar conversation.  The side bar conversation (100) may comprise several different types, including a public conversation or may constitute a private conversation or private text messaging or data exchange. A group conversation user wishing to hold the side bar conversation uses his user interface to alert other group conversation user(s) with whom he would like to hold the side bar conversation. Either the initiating user or the recipient user(s) can recommend the type of side bar conversation to be had using their user interfaces (51). If the side bar conversation is a voice conversation, the original group conversation can still be audible in the back ground, but can be reduced in volume relative to the side bar conversation or squelched in and out when the side bar conversation is active.

Inventor: SOMERS JOHN MICHAEL
IPC: C02F1/20
Filed: 2006-10-19
Abstract: A method for treating a process water from a bitumen recovery process in order to obtain carbon dioxide from the process water, which method includes lowering the pH of the process water, thereby causing carbon dioxide to evolve from the process water as evolved carbon dioxide gas. The evolved carbon dioxide gas may be collected and compressed, and water vapour associated with the evolved carbon dioxide gas may be separated from the evolved carbon dioxide gas. After the carbon dioxide has been obtained from the process water, the process water and the water vapour separated from the evolved carbon dioxide gas may be recycled back to the bitumen recovery process. The evolved carbon dioxide gas may be stored for future use or sale. The method may also include heating the process water in order to reduce the solubility of carbon dioxide in the process water.

Patent CA-2587474-A1 (CA)
Inventor: GALLANT ROBERT P
IPC: H04L9/30
Filed: 2005-11-14
Abstract: The present invention provides a new trapdoor one-way function. In a general sense, some quadratic algebraic integer z is used. One then finds a curve E  and a rational map defining [z] on E. The rational map [z] is the trapdoor one-way function. A judicious selection of z will ensure that [z] can be efficiently computed, that it is difficult to invert, that determination of [z] from the rational functions defined by [z] is difficult, and knowledge of z allows one to invert [z] on a certain set of elliptic curve points. Every rational map is a composition of a translation and an endomorphism. The most secure part of the rational map is the endomorphism as the translation is easy to invert. If the problem of inverting the endomorphism and thus [z] is as hard as the discrete logarithm problem in E, then the size of the cryptographic group can be smaller than the group used for RSA trapdoor one-way functions.

Title: Method and system for transcervical tubal occlusion
Inventor: HILARIO ESTELA H
IPC: A61B18/14
Filed: 2005-12-05
Abstract: A medical device and procedure is described for occluding a fallopian tube. A  tubal occlusion device is inserted into a uterine cavity. The device includes an RF applicator head including an electrode carrier with one or more bipolar electrodes thereon. During insertion, the RF applicator head can be in a closed position. The RF applicator head is positioned at a tubal ostium of a fallopian tube, such that a distal tip of the RF applicator head advances into the tubal ostium. The RF applicator head is deployed into an open position such that the RF applicator head approximates the shape of the uterine cavity in a region of the tubal ostium. Current is passed through the one or more bipolar electrodes to the tubal ostium to destroy tissue to a known depth, which precipitates a healing response in surrounding tissue that over time scars and occludes the fallopian tube.
