Title: Dual-functioning mechanism for startup during winding of web material and for splicing during unwinding
Inventor: ADAMS ANGELA HURST
IPC: B65H19/28
Filed: 2004-12-07
Abstract: A tail end of a web is attached to a winding core via a two-component mechanism having a core component attached to the core and a web component attached to the web, the two components being attached to each other in releasable fashion. The mechanism assists startup of winding. Upon completion of unwinding, the web component detaches from the core component to expose a region of adhesive on a part of the web component that extends from the tail end of the web. The tail end thus can be spliced to a leading end of another web by attaching the leading end to the exposed adhesive on the web component.

Patent CA-2505279-A1 (CA)
Inventor: TAYLOR RICHARD
IPC: B65B53/06
Filed: 2005-04-20
Abstract: A system for sealing a packaging wrapper around an object directs a flow of heated air to end flaps of the wrapper to move the end flaps into sealing contact with a body section of the wrapper to substantially enclose the object. The system includes an oven, a conveyor, a source of heated air and a means for deflecting the flow of heated air to the conveyor to seal end flaps of the wrapper with a body section of the wrapper. In use, an object surrounded by the wrapper body section is moved through the oven on a conveying surface of the conveyor, and heated air is moved through the oven bypassing the conveying surface to a region below the conveying surface. The heated air flow then encounters the means for deflecting the heated air flow, which directs the air flow upward and through the conveying surface to impact and move the end flaps into sealing contact with the wrapper body section.

Patent CA-2516391-A1 (CA)
Title: Scroll compressor with bifurcated flow pattern
Inventor: SULLIVAN BRIAN T
IPC: F04C29/02
Filed: 2004-02-09
Abstract: A scroll compressor includes various features that promote a bifurcated flow pattern of gas through a compressor shell to reduce oil entrainment. After entering the shell, some gas travels upward, which reduces the volume of gas traveling downward toward an oil sump. To accomplish this, the compressor's motor can be surrounded by a sleeve having upper and lower apertures for directing the flow to the motor's upper and lower stator end turns. In some embodiments, a suction inlet is strategically positioned relative to two gas passageways that are between the stator and the compressor shell. The inlet's position is such that one passageway receives incoming gas and divides the flow in opposite directions: upward and downward. The other passageway only conveys the gas upward. In addition, a suction baffle, a diffuser, a streamlined counterweight and/or a suction line oil trap can also help promote gas/oil separation or minimize oil entrainment.

Title: Obtaining tandem mass spectrometry data for multiple parent ions in an ion population
Inventor: MAKAROV ALEXANDER ALEKSEEVICH
IPC: H01J49/00
Filed: 2004-03-19
Abstract: This invention relates to tandem mass spectrometry and, in particular, to tandem mass spectrometry using a linear ion trap and a time of flight detector to collect mass spectra to form a MS/MS experiment. The accepted standard is to store and mass analyze precursor ions in the ion trap before ejecting the ions axially to a collision cell for fragmentation before mass analysis of the fragments in the time of flight detector. This invention makes use of orthogonal ejection of ions with a narrow range of m/z values to produce a ribbon beam of ions that are injected into the collision cell. The shape of this beam and the high energy of the ions are accommodated by using a planar design of collision cell. Ions are retained in the ion trap during ejection so that successive narrow ranges may be stepped through consecutively to cover all precursor ions of interest.

Title: Method for the production of deformed zeolites, and method for eliminating impurities from a gas stream
Inventor: ODOLO-HITZ SONJA
IPC: B01D53/04
Filed: 2004-04-07
Abstract: Disclosed is a synthetic zeolite by means of which gas streams containing steam and carbon dioxide as impurities can be purified. The zeolitic adsorbing agent is a 13X type or LSX type faujasite or a mixture of both types that are deformed with a binder, at least some parts of which are highly dispersed.  Said novel adsorption system allows extraordinarily high adsorption capacities to be obtained while keeping the mass transfer zones short, resulting in a longer service life of the adsorption systems before carbon dioxide is able to break through.

Title: Method and device for applying an adjustable tensile-stress distribution, in particular in the edge regions of cold-rolled metal strips
Inventor: PAWELSKI HARTMUT
IPC: B21B1/40
Filed: 2004-08-27
Abstract: The invention relates to a method and a device for applying an adjustable tensile-stress distribution, in particular in the edge regions during the cold-rolling of metal strips (16), in particular metal foil, in order to reduce the risk of an excessive build-up of tension and cracks at the edges of the strip, which can lead as a negative consequence to cracks in the strip and to a reduction in production, and in order to improve the surface of the strip and its planarity, even for a relatively high strip displacement speed, and also to reduce strip trimming widths. To achieve these aims, at least one or a combination of two of the following measures are implemented: a) separation of lubrication and cooling of the working rolls by lubricating on the run-in side and cooling on the discharge side, b) additional influencing of the strip edges using a hot edge spray", in particular by spraying (21) rolling oil with differing temperatures in zones, c) use of a special cross-sectional configuration of the working rolls (12, 12') in the vicinity of the strip edges, which creates a partial material build-up during the blooming pass, said build-up forming a longer strip edge with subsequent passes, thus counteracting the risk of an excessive build-up of tensile stress.
