Title: Water-closet disposable pouch and method of disposal
Inventor: STEER GRAHAM EMERY
IPC: A61F5/441
Filed: 1997-06-26
Abstract: A water-closet disposable pouch (8) has a pull-away tab (20) secured to one wall (10) by a weld or bond (22). Pulling away the tab (20) tears open the pouch wall (10) along the weld or bond by tearing out material (30) from the weld, thus creating one or more gaps (28). The tab (20) may be V-shaped, and define a flap or hatch area (26) of the wall behind the tab (20) which is released when the tab (20) is torn away. Any gas trapped in the pouch can escape through the opening when the gas is placed in a WC. In an alternative form, a tear-out filament is secured to or within a wall of the pouch parallel to a direction of orientation of the plastics material.
Patent CA-2213509-A1 (CA)
Inventor: HUFF KARL
IPC: B01D61/12
Filed: 1997-08-15
Abstract: A filtration system and assembly for a wide variety of liquid mixture applications is disclosed. The system comprises a pump, filter, concentrate release, aspirator, and by-pass that incorporates a flow control valve.  The flow control valve controls the flow and pressure of the fluid recycling within the system thereby simultaneously controlling permeate outflow from the filtration system and feedstock inflow into the filtration system.      All components are configured in a closed loop. System stability and high permeate flow result from the optimum selection of system components.  The aspirator is passively controlled and very efficient at sucking the optimum amount of feedstock into the filtration system.  Therefore, the disclosed system is simpler to control, easier to operate, easier to maintain, more energy efficient, and more compact than continuous prior art filtration systems in use.

Patent CA-2221167-A1 (CA)
Inventor: LOH WEI-HUNG
IPC: G02B6/10
Filed: 1996-05-14
Abstract: A method of forming optical waveguide gratings, such as in-fibre gratings, is described. The gratings are formed optically, with a phase mask being scanned by a writing laser beam to generate the grating pattern. The waveguide and phase mask are moved with respect to one another during the writing process, to vary the grating properties along the length of the grating. Relative move-ment in a single direction provides a change of grating pitch, and so can be used to fabricate chirped or multi--wavelength gratings. Bi-directional dither alters the strength of the grating, and so can be used to fabricate apodised gratings.

Abstract: L'invention se rapporte au plasmide pLP?2¿-1531, qui code les chondroitinases I et II, et au plasmide pLP?2¿-1521, qui code la chondroitinase I. On utilise ces plasmides pour transformer les cellules E. coli et P. vulgaris de type sauvage. Les cellules transformées produisent de l'ADN qui code la production des chondroitinases I et II ou de la chondroitinase I en l'absence des inducteurs exogènes naturels des chondroitinases I et II. En outre, les cellules transformées de P. vulgaris produisent en l'absence des inducteurs exogènes des chondroitinases I et II les enzymes respectifs dans des proportions supérieures à celles produites par le P. vulgaris de type sauvage en présence du ou des inducteurs exogènes des chondroitinases I et II. Le plasmide de départ pLP?2¿-751 et les plasmides intermédiaires pLP?2¿-770, pLP?2¿-1512, pLP?2¿-1263, pLP?2¿-1508, pLP?2¿1510, pLP?2¿-1514, pLP?2¿-1518, et pLP?2¿-1525 sont également décrits dans l'invention. Ces plasmides intermédiaires sont généralement utilisés dans la préparation des plasmides pLP?2¿-1531 et pLP?2¿-1521. On décrit par ailleurs un fragment BglII/EcoRI d'environ 3970 bp provenant du plasmide pLP?2¿-1512, un fragment EcoRI/SmaI d'environ 2550 bp provenant du plasmide pLP?2¿-1514, et un fragment BglII/SmaI(AvaI) d'environ 6520 bp provenant du plasmide pLP?2¿-1518. Enfin, on envisage l'utilisation des cellules transformées de P. vulgaris en vue de produire la chondroitinase I et/ou la chondroitinase II. Lesdites cellules P. vulgaris sont mises en culture dans un milieu de culture bactérienne, en l'absence d'inducteur exogènes des chondroitinases I et II. Une fois les cellules recueillies, on peut extraire les enzymes que constitue la chondroitinase I et/ou la chondroitinase II.

Title: Improvements relating to the laying of underwater pipeline
Inventor: LANG CRAIG ALEXANDER
IPC: F16L1/20
Filed: 1998-01-16
Abstract: A pipelaying vessel includes a pipe carrying drum (30) mounted with its axis parallel to the fore-aft direction of the hull.  A launch structure (36) consists of telescopic arcuate members (38 and 58) which are relatively moveable to vary the launch angle.  Pipe engaging clamps (46 and 48) engage the pipe along a curved path, and are reciprocally moveable along a curved track to tension the pipe.  The curved path has an angle of curvature which is approximately equal to the residual curvature of the pipe drawn from the drum.  The launch angle can also be adjusted by moving the angle or position of the curved path within a plane which is substantially perpendicular to the drum axis.  An abandonment and recovery system is mounted on the launch structure, which is moveable alongside the drum as a level wind.

Inventor: EIFRIG ROBERT O
IPC: H04N7/26
Filed: 1998-02-25
Abstract: DC and AC DCT transform coefficients of an INTRA coded block (310) are differentially encoded by selecting predictor DC and AC coefficients from a left-hand neighboring block (320) and a top neighboring block (340). Each block (310, 320, 340) is coded according to a frame mode, a reordered field mode, and a non-reordered field mode. The AC predictor block is selected according to the respective coding modes of the blocks, and the block in which a DC predictor resides. The top block (340) is selected as an AC predictor when the top block (340) and current block (310) are both reordered field mode, or both frame mode and/or non-reordered field mode, and the DC predictor resides in the top block. Zeroed AC spatial transform coefficients are used in place of the AC spatial transform coefficients from the selected block when the selected block is not INTRA coded, or does not reside in the same Video Object Plane (VOP) as the current block. DC coefficients may be non-linearly quantized.

IPC: C07K19/00
Filed: 1996-09-30
Abstract: Lantibiotics, such as nisin and subtilin, are peptides that are substantially modified post-translationally, such as by dehydration of serines and threonines and by formation of thioether crosslinkages. Lantibiotics are synthesized with a leader region that directs proper processing; this leader is specific both for the synthesizing organism and for the mature sequence. Chimeric lantibiotics were synthesized that contained the subtilin leader region and either a subtilin-nisin fusion or a nisin-subtilin fusion for the mature region. The nisin-subtilin chimera was efficiently processed into a functional lantibiotic, but the subtilin-nisin fusion produced a heterogeneous mixture of products, none of which had the expected properties of a correctly process polypeptide. This mixture contained a minor component with a specific activity exceeding that of nisin itself.

Inventor: YURCHISION PETER P
IPC: F16K11/074
Filed: 1998-03-18
Abstract: Multi-port valve assemblies with, typically, two-piece housings are disclosed.  Particularly useful in connection with swimming pools and associated water pumps, the assemblies avoid reliance on an elongated handle to effect rotation of the internal structure of the valve.  Instead, the assemblies utilize a knob--which users need not lift--coupled to a post in which an elongated slot is formed.  Doing so avoids breakage problems associated with use of elongated handles while reducing wear of internal seals.  Each valve assembly additionally may include a cam having non-semicircular, asymmetrically-shaped recesses into which followers attached to a shaft passing through the elongated slot are received.
