Patent CA-2216237-A1 (CA)
Inventor: DRUESSEL HERMANN
IPC: B65D17/40
Filed: 1996-03-15
Abstract: The invention concerns a method of closing off the mouth of a container with a closure (11) which is designed to be peeled off the container-mouth rim (7).  The method is characterized in that placed on a first strip of material (1) in the closure (11) is at least one second strip of material (2) which partly covers the first strip of material (1). The two strips (1, 2) are then coated with a sealing agent (5) at least over the area of the rim formed between the two strips. In a subsequent operation, the part of the container rim (7) adjacent to the mouth is then joined to the first and second strips (1, 2) round the whole mouth to form a peel-off closure, the second strip (2) covering a section of the container-mouth rim in such a way that the part of the first strip (1) located on the side of the closure (11) remote from the inside of the container which overlaps the second strip (2), and is therefore free of sealing agent, forms a tear-off tab. The invention also concerns a container (10) with a closure (11) of this kind and a material (3) suitable for manufacturing the closure (11).

Patent CA-2236573-A1 (CA)
Inventor: MELETIS ELEFTHERIOS
IPC: F02B53/04
Filed: 1997-09-08
Abstract: A vaned rotary engine with a cylindrical (circular cross section) stator (1) and a multilobed rotor (2) having the same axis with the cylinder. The rotor is keyed to a shaft (3), supported on the baseplate (11) through the bearings (14). The rotor lobe tips (17 and 18) provide a sufficient blocking of the combustion chamber (12) to allow for a (nearly) constant combustion process. This chamber is embedded in the stator wall and the fuel is injected into it through the injection nozzle (8). The four volumes needed for the thermodynamic processes, i.e. the inlet (21), the compression (13), the expansion (20) and the exhaust (19), are formed by the two cavities formed between the stator inner surface and the rotor outer one with the help of three diaphragms. The first diaphragm (9) separates the inlet-exhaust volumes and is continually in touch with the rotor surface. The other two are positioned very close to the combustion chamber, one in front (7) and the other behind it (6), as the rotor rotates. The back diaphragm is initially in contact with the rotor surface while the other is recessed. When the pressures in the compression and the expansion volumes are nearly equal, the two diaphragms exchange position, by lowering the front one and withdrawing the back one. This exchange leads to a mixing of a part of the flue gasses with the air, thus acting as a regenerative preheating mechanism for the air.

Patent CA-2241497-A1 (CA)
Title: Polyurethane thickeners for clear aqueous-based systems
Inventor: DOOLAN JOSEPH
IPC: C09D175/08
Filed: 1998-06-24
Abstract: The present invention relates to improved thickening compositions, often referred to as rheological additives, used to provide viscosity control, flow, leveling and other rheological properties to clear aqueous systems such as automotive clear-coat paints and coatings. The invention hereof involves the synthesis of a new family of rheological additives by combining, through a reaction process, chemicals used to make specified polyurethane polymer compositions. These novel copolymers provides the good flow and leveling and gloss retention that polyurethane associative thickeners impart to water-based systems, without the loss of clarity that such polymers have caused in the past. Levels of the rheological thickening composition, varying between about 0.01% and about 10%, based on the total weight of the system to be thickened, have been found to be useful to create novel clear aqueous systems containing such thickening compositions.
