Patent CA-2224011-A1 (CA)
Title: Improved process for selective hydrogenation of highly unsaturated compounds and isomerization of olefins in hydrocarbon streams
Inventor: PUTMAN HUGH M
IPC: C10G45/06
Filed: 1996-06-27
Abstract: A process for treating C3 to C12 petroleum fractions, such as a light cracked naphtha to be used as an etherification feed stock in which H2S is removed by distillation of at least the C3 fraction and mercaptans and diolefins are removed simultaneously in a distillation column reactor (20) using a dual catalyst bed (22, 24). The mercaptans and H2S are reacted with the diolefins in the presence of a reduced nickel catalyst (22) to form sulfides which are higher boiling than the portion of the feed which is fractionated to an upper hydrogenation catalyst bed of palladium (24) for hydrogenating diolefins and acetylenes. The higher boiling sulfides are removed as bottoms (110) along with heavier materials. Any diolefins not converted to sulfides and acetylenes are selectively hydrogenated to mono-olefins in the presence of a palladium oxide catalyst in an upper bed (24), producing overheads (116), substantially free of sulfur compounds, diolefins and acetylenes.

Patent CA-2242306-A1 (CA)
Inventor: KAMP DAVID C
IPC: B41J2/175
Filed: 1998-07-02
Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure.  The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir.  The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink.  However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer.  The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

Title: Food material decurling apparatus and method
Inventor: RATTMANN JAMES A
IPC: B26D7/06
Filed: 1998-07-21
Abstract: An apparatus for decurling a sliced food material, for use with an automated slicer wherein the food material is carried in a reciprocating arcuate or linear movement. The sliced material is passed through a constricted space between separate stationary and moving surfaces. The moving surface moves relative to the stationary surface at a speed that is at least as fast as the speed at which the food is carried towards the knife. The moving surface is incorporated within a guide plate which has a profile that approximates the arcuate or linear path of the food in its travel into and out of contact with the knife. The moving surface may consist of an array of rotatably driven elastic bands or belts that travel within a series of grooves within the guide plate, and which are driven by a driving roller. The belts serve to transfer the sliced food to another work station and prevent the food supply from being pinched against the guide plate.

Patent CA-2244572-A1 (CA)
Inventor: GU XIJIA
IPC: H01S3/067
Filed: 1998-08-07
Abstract: Optical fiber transmission filters and methods of producing the filters with preselected transmission spectra are disclosed. The transmission filters include a long-period grating (LPG) having a first grating section and a second grating section spaced from the first section by a phase gap. The presence of a phase gap in the LPG introduces a phase shift wherein the amplitude of the electromagnetic radiation passing through the first section adds vectorially to the amplitude of the light passing through the second section with an angle .PHI. related to the phase gap. When the gap length .DELTA. equals to a half grating period a (a=~/2), a .pi. phase shift is introduced between the light transmitted through the two parts. By carefully selecting the length L1, the period of the two sections and the gap .DELTA. to give a preselected phase shift, the transmission loss peak can be designed to meet preselected specifications. Transmission filters for gain flattening of erbium-doped fiber amplifiers, notch filters, filters for suppression of amplified spontaneous emission and the like have been produced. Also disclosed are filters including chirped cascaded long-period gratings that exhibit multiple loss peaks over a wavelength band as broad as 240 nm.
