Patent CA-2225261-A1 (CA)
Title: Treatment method for water containing nitrogen compounds
Inventor: JOKO ISAO
IPC: C02F1/467
Filed: 1997-12-18
Abstract: Waste water containing nitrogen compounds is treated by first breaking the nitrogen compounds down by electrolysis in the presence of chlorine ions. The electrolysis step converts chlorine ions to hypochlorite ions. The partially treated water is returned to a storage container. The hypochlorite ions oxidize the nitrogen compounds and are reconverted to chlorine atoms. The partially treated water then may be returned to the electrolysis container to regenerate hypochlorite ions. In a second step, the partially treated waste water is passed over a metal peroxide catalyst. The metal peroxide catalyst further breaks down the nitrogen compounds, and removes the excess hypochlorite ions.

Abstract: A two way mailer formed of a single blank of sheet material is disclosed and comprises first and second sections, and a first fold line about which the second section may be folded onto the first section.  The first section includes a first panel including top, bottom and side edges.  The second section includes second and third panels each including top, bottom and side edges, with the top edge of the second panel being coincident with the first fold line. The second and third panels are foldable onto one another about a second fold line coincident with the bottom edges of the second and third panels to form a folded second section.  The second section also includes a pair of perforated lines extending through at least the second panel and being substantially perpendicular with the first fold line.  The perforated lines define side edges of a return postcard within the thus folded second section.  The thus folded second section may then be adhered to the first section to thereby form a forwarding envelope.  The return postcard may then be separated from the forwarding envelope along the pair of perforated lines and the first fold line.  In alternative embodiments, the two way mailer may be formed of a composite including first and second sections where both sections are formed from a single material having a minimum thickness of about 0.007 inches.

Patent CA-2254864-A1 (CA)
Inventor: PFEUFER LOTHAR
IPC: E06B9/15
Filed: 1998-12-01
Abstract: The invention refers to the joints of the roller blind-, roller grille-, roller shutter profiles which increase the safety standard of roller blinds because of their specific shape and therefore operate without additional locking device. According belonging to the invention, the cross sections of the joints show a spiral shape with a specific curvature belonging to the invention.  Therefore the spiral shape is created by the design of the inside bends and outside bends of each analysed spiral part which enclose with certain opening widths the respective joint capsules of the profiles.  Because of the specific spiral of the core- and link profiles which are liked with each other and because of the twisting of the spiral joints by an angle of 180° the unauthorized attempt of pushing up of the roller blind results in a jamming of the profile elements that leads to the locking of the roller blind.

Title: Transfer system for products and utilities
Inventor: FERREIRA PAULO PAZ RIBAS
IPC: B63B21/50
Filed: 1996-10-30
Abstract: The present invention relates to a system which makes use of a multiple reel on which groups of flexible lines supported by articulated structures (8, 9) are wound. The groups of flexible lines are interconnected at one end to flexible production and utility lines (4) emerging from the sea-bed and, at the other end, to connection blocks (10, 11) which may be connected to connection plates (15, 16, 17, 18) on at least one connection tower (13, 14) fixed to the vessel. As the connections are redundant, it is always possible to reposition one group of flexible lines while another group is connected, which gives the transfer system (2) total freedom of movement.

IPC: H04W76/02
Filed: 1997-09-15
Abstract: After an initial call connection (20) towards a called party mobile station (10), an originating exchange (70a) serving the calling party terminal receives an indication (115, 125) over the connected telecommunications network that the entered called party number is associated with a mobile station. Thereinafter, the serving originating exchange interrogates (150) the HLR (50) directly to determine the mobile switching center (MSC) (70b) currently serving the called party mobile station for subsequent outgoing call connection requests towards the called party terminal. After retrieving the roaming number representing the serving MSC for the called party mobile station, a direct call connection (190) is established between the originating exchange and the MSC currently serving the calling party mobile station without establishing a trunk call connection back to the home Public Land Mobile Network (PLMN) associated with the calling party mobile station.

Inventor: SCHROEDER WEN ZYO
IPC: D21H17/13
Filed: 1997-09-30
Abstract: The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a silicone quaternary and, optionally, one or more softeners/debonders into the fiber furnish at the wet end of the tissue machine prior to formation, followed by an optional topical treatment with a silicone quaternary and/or one or more softeners/debonders after the tissue web is formed. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

Inventor: HEATER THOMAS JOHN
IPC: F02F7/00
Filed: 1999-04-06
Abstract: A cylinder block isolator core for use in casting engine cylinder blocks for internal combustion engines. The isolator core cooperates with companion core elements in a casting operation to form a short coolant jacket surrounding the upper portion of each engine cylinder adjacent the air/fuel combustion chamber and an air pocket that surrounds the lower region of the cylinder. Drainback passage core elements may be formed integrally with the isolator core thereby reducing the total number of cores in the casting mold package during a casting operation, the finished casting thereby eliminating dividing walls between the isolator and the oil drain cores thus reducing the number of core elements and reducing the cost and complexity of the casting operation as well as reducing the weight of the finished casting. The isolator core may be used independently of cylinder liners during the casting operation. Alternatively, the isolator core may be used in combination with cylinder liners to simplify the casting operation and to reduce further the total weight of the finished casting by eliminating one cylinder bore wall at the lower region of the cylinder.

Title: System and method for remedying a permeable mass
Inventor: PARRY JULIAN DAVID
IPC: C05F17/00
Filed: 1998-07-06
Abstract: The present invention is devised to facilitate the treatment, by biotic or abiotic means, of a permeable mass of mixed or selected materials, gathered within a refillable containment. The purpose of such treatments is to obtain either a physical and/or chemical change in the composition of the mass and/or contaminants within it, by the manipulation of biotic and abiotic activity in the subsurface environment. The invention is an adaptation of the SBS Close Lance system contrived for the decontamination of polluted soil. Such a system, when fitted to a suitably constructed refillable containment may be used to compost and decontaminate remediable materials by promoting and exploiting biotic and abiotic activity. The principal users of the invention will be those involved with the ex-situ treatment of remediable materials including soils, refuse, wastes, drilling muds and minerals. A  widespread benefit will be the composting of waste prior to alternate use by recycling.

Title: Facade system with a translucent porous insulating material
Inventor: SCHLOEGL JOACHIM
IPC: F24J2/00
Filed: 1998-10-21
Abstract: The present invention relates to a façade system with a translucent porous insulating material of mineral or organic fibres for passive solar energy utilization, the insulating material having on the outside a coloured layer (2) for design purposes and for controlling the light transmittance. The façade system is formed from a multiplicity of preferably factory-prefabricated façade insulating boards (1). The coloured layer (2) can, moreover, be designed in such a way that it protrudes beyond the insulating layer along two board edges (3, 4). Consequently, when the façade insulating boards (1) are applied to the building wall, the abutting edges in the region of the joins between neighbouring insulating boards are covered by the overlapping protruding;  coloured layer (2).
