Title: Poly(vinyl alcohol) copolymer ionomers, their preparation and use in textile sizes
Inventor: HAYES RICHARD ALLEN
IPC: D06M15/333
Filed: 1996-12-12
Granted: 2008-08-19
Abstract: Compositions and textile sizes based on those compositions, which are particular poly(vinyl alcohol) copolymer ionomers, as well as blends of those ionomers with other sizing polymers are described. A process to prepare the ionomers is described. The compositions are poly(vinyl alcohol) copolymers which have carboxylic acid ionomer comonomer units. Sizes based on these ionomers are aqueous solutions of the ionomers or solutions of blends of them with other poly(vinyl alcohol ) polymers which are not ionomeric, or solution/suspensions of the ionomers with various starches, or both. Desizing in either water or caustic solutions is generally far superior to comparable polymer blends which contain no poly(vinyl alcohol) copolymer ionomer.

Title: Ion source for a mass analyser and method of providing a source of ions for analysis
Inventor: BAJIC STEVAN
IPC: H01J49/10
Filed: 1998-04-28
Granted: 2006-11-07
Abstract: An ion source for a mass spectrometer operating at a low pressure has an atmospheric pressure sample ioniser which provides a sample flow containing desired sample ions. These ions are usually entrained with undesired gas and droplets. An interface chamber is held by a vacuum pump at a pressure between atmospheric and the operating pressure of the mass spectrometer. Sample ions with entrained gas are collected through an entrance orifice forming a stream of gas into the interface chamber. Sample ions exit the interface chamber through an exit orifice to the mass spectrometer. The interface chamber disrupts the stream of gas entering the interface chamber to provide a dead region having no net gas flow direction and the exit orifice is located in this dead region. The exit orifice should have no line of sight path to the entrance orifice or should be at least 30.degree. off the flow axis of the stream entering the interface chamber through the entrance orifice. A flow disrupting pin is located in the interface chamber to disrupt the flow of the stream of gas entering through the entrance orifice.

Abstract: An over-the-highway truck or tractor equipped with a gear shift lever selectively foldable from an operating position to a folded position is disclosed.      The gear shift lever includes upper and lower lever portions relatively telescopically and rotatably connected. The upper lever portion includes a generally L-shaped slot, while the lower lever portion carries a pin slidably engageable with and guided by the L-shaped slot for relative guiding movement of the lever portions. A tapered leg of the slot is arranged to allow relatively telescopic and pivotal movement between the lever portions and a foot of the slot extends laterally from the leg. The foot allows relatively rotatable movement between the lever portions to engage the pin and foot in the operating position. A coil spring urges the lever portions apart so that when the pin is within the leg the lever portions are relatively moveable axially.     When the pin is within the leg the spring urges the first and second lever portions apart a predetermined distance. When the pin is positioned near an end of the leg remote from the foot, the portions are relatively pivotable between the aligned and out of the way lever portions.

Abstract: The invention relates to a rotating stitcher (4) for driving U-shaped wire stitches (43) into printed products (3) being conveyed along a linear path. The invention also relates to a stapling closing device (5) co-operating with the stitcher (4), for closing the wire stitches (43). The rotating stitcher (4) has stitching heads (7) which are hinged around a rotating support (6). A control device guarantees that the stitching heads (7) are swung into a position where the direction of displacement (E) of the stitch plunger (10) is at right angles to the direction of transport (A) of the products (3) to be stitched. This takes place before or during entry of the stitching head (7) into the stitching area. While the wire stitches are driven in and stitched, the stitching heads (7) are held in this position and thus move linearly in the stitching area. The heads (32) of the stapling closing device (5) are guided in the same way, so that they move linearly during stapling, just like the allocated staple head (7).
