Patent CA-2169970-A1 (CA)
Inventor: RAMSEY JAMES ALLEN
IPC: G09F15/02
Filed: 1996-02-21
Abstract: In a structure in which a poster can be hung,  polyester  film  is  cut  to  a  unique design.  The film is sized to cover the entire front of the poster.  Four extensions extend from each corner of the film,  providing an area for a thumb tack.   The top area of a separately cut tab is covered with clear two-sided tape.  One tab is affixed to the back of each of the four existing extensions.   Once placed  face  down  upon  the  back  of  the polyester film, each corner of the poster is secured into their respective tab.  The beauty of the poster is greatly enhanced and is also perfectly preserved in its natural state.

Title: Vaccine compositions comprising live bacterial vectors for protection against yersinia pestis injection
Inventor: TITBALL RICHARD WILLIAM
IPC: A61P31/04
Filed: 1994-12-23
Abstract: Novel DNA constructs are provided that are capable of transforming such that they can be used as live or attenuated vaccines which induce such immune response at mucosal surfaces. Further provided are such transformed microorganisms per se and vaccine compositions containing them. Preferred constructs of the invention are capable of transforming microorganisms such that they express F1 based protein while retaining a capability to establish themselves in human or animal gut environment. Several constructs have been identified that are capable of transforming gut dwelling organisms such as S. typhimurium or S. typhi to enable F1 antigen production, but most of these affect the organism such that it can no longer function effectively in the gut, at least in so far as it cannot express the antigen e.g. being unstable and losing plasmid.

Title: Method of managing software by transmitted data on network
Inventor: TOBITA MASAHIRO
IPC: A63F13/33
Filed: 1997-01-07
Abstract: A user buys software having a product code stored in a CD-ROM. A use-charge of the software is paid. The use-charge is determined by the user in correspondence with a use frequency of the software before the software is used. When the use-charge of the software is paid, the key code management table in a host computer is updated. The user's computer is connected with the host computer on a network, then the user gets a usable time and a key code of the software. Thus, the user can use the software within the usable time corresponding with the use-charge. Therefore, the use-charge and a public network fee can be collected reliably.

Title: Process for preparing a particularly pure glycolic acid
Inventor: EBMEYER FRANK
IPC: C07C51/42
Filed: 1997-01-09
Abstract: The present invention relates to a process for preparing a particularly pure glycolic acid by saponification with chloroacetic acid with an excess of alkali metal hydroxide, with the resulting alkali metal chloride being filtered off, and the 20 to 70% strength by weight glycolic acid solution being subsequently subjected to anelectrodialysis at 20 to 40°C and a cell voltage of 0.5 to 2.5 V per cell pair. The process of the invention permits optimum removal of sodium chloride and chloroacetic acid as necessary for preparing a particularly pure glycolic acid. Other organic acids, nitrogen compounds, aldehydes and salts are not produced in this process and thus do not affect the product quality.

Patent CA-2206338-A1 (CA)
Title: Improved catch basin
Inventor: MONTEITH JOSEPH GORDON
IPC: E02D29/12
Filed: 1997-05-28
Abstract: An improved catch basin is constituted by a cylindrical container with a partition dividing the internal volume into a lower compartment and an upper compartment. The partition includes an intake region and an outlet region, each communicating with a vertical pipe extending downwardly from the partition and opening into the lower treatment chamber at an intermediate location therein, the intake region and the outlet region being diametrically opposite one another.  The partition defines a central, oblique ramp which urges entering liquid in the direction of the intake opening of the intake region. Thus, under conditions of low liquid flow into the catch basin, all entering liquid will be directed to the intake region, descending along the intake conduit and into the lower compartment.  Conversely, under conditions of high liquid flow into the catch basin, a portion of the liquid will overrun the ramp and gain direct access to the outlet region, from which it will exit the catch basin.
