Patent CA-2048961-C (CA)
Title: Package container provided with a strip-type opening arrangement
Inventor: KJELGAARD TOM
IPC: B65D5/74
Filed: 1991-08-12
Granted: 2000-11-21
Abstract: The disclosure relates to a package container provided with an opening arrangement and consisting of a plastic-coated packaging material, comprising a sealing fin (3) extending transversely over a container wall (4) and in which there is inlaid an opening strip (10) of laminate material whose pull-off entails that the sealing fin closing the container wall (4) is unseated for exposing a corresponding pour aperture.      The opening strip (10) includes an inner layer (14) and outer sealable plastic coatings (15) and an intermediary layer (16) disposed between the inner layer (14) and each respective outer plastic coating (15). In order to facilitate opening of the package container, the intermediary layer (16) of the opening strip (10) consists of a material of such properties that the bonding strength between all material layers included in the opening strip and between the outer thermoplastic coatings (15) and opposing plastic coatings (12) of the packaging material in the sealing fin (3) is greater than the internally cohesive bonding strength of the intermediary layer (16), whereby the opening strip (10) undergoes a cohesive delamination within the intermediary layer (16) when the opening strip is pulled-off.

Title: Sox/nox sorbent and process of use
Inventor: ZIEBARTH MICHAEL SCOTT
IPC: B01D53/00
Filed: 1992-02-06
Granted: 1997-03-11
Abstract: An alumina sorbent capable of adsorbing NOx and SOx from waste gases and being regenerated by heating above 600°C is made by incorporating an alumina stabilizing agent into the sorbent.  A preferred method is to add the stabilizer when the alumina is precipitated.  The precipitated powder is formed subsequently into a slurry, milled and dripped to form the stabilized spheroidal alumina particles.  These particles are impregnated with an alkali metal or alkaline earth metal to form the stabilized sorbent.  Alumina stabilizers include one or more of silica, lanthana, other rare earths, titania, zirconia and alkaline earths.

Title: Latency associated peptides and uses therefor
Inventor: LEVINSON ARTHUR
IPC: C07K14/495
Filed: 1990-10-30
Granted: 2002-02-12
Abstract: An isolated nucleic acid sequence is provided that comprises a sequence that encodes a latency associated peptide having a molecular weight of about 75,000 when measured by non-reducing SDS-PAGE and capable of antagonizing a biological activity of mature TGF-.beta., provided that the sequence does not also encode a mature TGF-.beta.. The latency associated peptide so produced is useful therapeutically in blocking a deleterious activity of an endogenously released or exogenously administered TGF-.beta., alone or in combination with another exogenously administered or endogenously released immune regulator. It is also useful as a cotreatment therapy with mature TGF-.beta., which forms a latent associated complex therewith that is activatable at the desired site in vivo.

Title: Controlled slew rate amplifier
Inventor: GAILUS PAUL HOWE
IPC: H03G3/30
Filed: 1991-09-10
Granted: 1996-03-26
Abstract: An adjustable slew rate amplifier (26) in the input stage of an amplifier circuit (10) helps reduce off-channel frequency splatter. In instances where test sequences are input to an amplifier circuit that are used to measure maximum permissible input levels to the amplifier (34), inclusion of a low slew rate amplifier in the input loop further prevents the production of off-channel frequency splatter caused even by the input test sequence. The adjustable slew rate amplifier (26) is run at full slew rate, providing full-bandwidth amplification, during periods of normal circuit operation.

Patent CA-2112489-C (CA)
Inventor: BRINK POUL ERIK
IPC: A21C11/00
Filed: 1992-06-29
Granted: 2004-03-30
Abstract: In the production of various kinds of pastry it is actual to effect a folding-over of wing portions of flat dough members, such that these portions are folded down over some stuffing deposited e.g. on a middle area of the dough member. While this is easily done manually, it has been very difficult to automatize the operation, but according to the invention this is achieved in a very simple and efficient manner. A rubber resilient shaping plate is used, which, through foldable areas, is connected with projecting wing portions each associated with a depending rubber rod. At their lower ends these rods are rigidly attached to an actuator plate, which, in being raised relative to the shaping plate, urges the rubber rods upwardly for folding the wing portions up- and inwardly. Hereby the rubber rods will be bent, and due to the tensions thus produced a further raising of the actuator plate can result in the rods causing the wing portions to be folded inwardly over and down towards the shaping plate.

Title: Biological screens for detection of herbicides
Inventor: BASCOMB NEWELL F
IPC: C12N9/00
Filed: 1994-01-27
Granted: 2009-07-14
Abstract: This invention pertains to novel protocols for the screening and rapid identification of compounds that specifically inhibit a predetermined enzyme or metabolic target site or pathway that is specific to plants. Enzymes which are specifically or indirected affected by the novel screens include glutamine synthetase (GS), 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHP), dihydrodipicolinate synthase (DHPS), acetohydroxyacid synthase (AHAS) and phosphoribosyl anthranilate transferase (PAT). The enzymatic pathways targeted by the novel screening protocols are unique to plants, bacteria and fungi and are present at low levels. Thus, inhibiting these enzymes should present little or no toxicity to humans or animals. The screens provide an efficient and rapid method for assessing the herbicidal potential of test compounds. Lead compounds identified by the novel screening protocols can be used as herbicides to inhibit growth.

Title: Diversity antenna structure having closely-positioned antennas
Inventor: VANNATTA LOUIS JAY
IPC: H04B7/08
Filed: 1993-12-07
Granted: 1997-10-14
Abstract: A diversity antenna structure (500) and a diversity transceiver incorporating the same are provided.  Each antenna of the diversity antenna structure is formed of a first portion (516, 525) and a second portion (520, 527). Second portions (520, 527) of each antenna are coupled to an electrical ground plane and form thereby ground plane portions of the respective antennas.  Such second antenna (520, 527) are maintained in physical isolation from one another thereby, when receiving high frequency signals, to be maintained in apparent electrical isolation from one another.  Because such ground plane portions are maintained in the apparent electrical isolation from one another, antennas of the diversity antenna structure may be positioned in close proximity to one another without causing coupling between the separate antennas of the diversity antenna structure.
