Patent CA-2313712-A1 (CA)
Title: An acoustic ink jet printhead design and method of operation utilizing flowing coolant and an emission fluid
Inventor: HADIMIOGLU BABUR B
IPC: B41J2/04
Filed: 2000-07-11
Abstract: A droplet emitter with an array of droplet emitting devices constructed such that one flowing liquid is used to create the droplets while a second low acoustic impedance liquid can be used to both make the transfer of acoustic energy to the first liquid more efficient and help maintain a uniform temperature of the droplet emitter array. Both the emission fluid and the low acoustic impedance fluid can be circulated through the droplet emitter to allow for excess heat generated by control electronics to be transferred to the flowing. This prevents for instance excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.

Title: Method and apparatus for transferring data files retrievable via a communications network
Inventor: KERMANI BAHRAM GHAFFARZADEH
IPC: G06F12/00
Filed: 2000-12-11
Abstract: A method for transferring a data file retrievable via a communications network, such as the Internet or World Wide Web. A data file desired and selected by a user is electronically transmitted to a third party, referred to herein as the "receiving agent". After receiving the file, the receiving agent stores the file on a transportable medium, such as paper or a computer readable medium, such as a CD-ROM, and transports the transportable medium to the user, e.g., by postal service or courier. In this manner, the user receives the data file he desires by a method other than electronic transmission. In one embodiment, the user is given an opportunity to view a list of user-selected files and to modify and/or confirm delivery of the files before they are downloaded to the receiving agent and/or delivered to the user.      Apparatuses for carrying out the inventive method are also provided.

Abstract: The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.

Abstract: Le soufre est éliminé des combustibles fossiles contenant du soufre par incubation du combustible avec des microbes isolés et purifiés du sol ou de la terre, permettant l'extraction sélective du soufre sans utilisation apparente dudit combustible comme source de carbone ou d'énergie. Les microbes de biodésulfuration préférés extraient au moins environ 20 % du soufre. Les microbes sont obtenus dans un tamis à étapes multiples sélectionnant tout d'abord les micro-organismes utilisant du dibenzothiophène (DBT) comme unique source de soufre, et les testant ensuite dans des incubations avec des combustibles fossiles; les organismes désulfurant le DBT sans métaboliser les structures à cycle phényle du DBT et désulfurant les combustibles, uniquement lorsqu'une seconde source de carbone dépourvue de soufre est présente, sont identifiés et employés dans les processus de désulfuration. Deux cultures, CDT-4 et CDT-4b, se sont avérées particulièrement efficaces dans la désulfuration des combustibles fossiles liquides.

Abstract: The invention relates to a scanning method and a scanning apparatus for optical density measurement of preferably at least one measurement object arranged on a printing medium, with sensor means for scanning the measurement object.  The invention envisages that the sensor means comprise a number of measurement heads, and that, in a manner dependent on the detection - performed by means of a selected measurement head - of a reference object arranged on the printing medium at a distance from the measurement object which is predetermined in the transport direction of the printing medium, the measurement heads which are thereupon activated detect and scan the measurement object. To that end, the measurement object is designed as a measurement strip which extends transversely with respect to the transport direction of the printing medium along the width thereof and has a linearly arranged chain of measurement fields having specific color density values. An individual measurement field of a further measurement strip can be used as the reference object.
