Title: Double-wall tank and method of its manufacture
Inventor: BACHMANN WERNER
IPC: B29C63/00
Filed: 1992-07-24
Granted: 1996-04-02
Abstract: To improve the strength, resistance to leaks, and formation of tears and fissures in the inner wall of a doublewall tank, the inner wall is formed, as described in the inventor's earlier Patent 4,739,895 (Re 33,421) by a plurality of foil or sheet elements which are overlapped at the edges, and covered by a plastic, preferably epoxy layer. The sheet elements are preferably aluminum foils of from 0.15 to 0.3 mm, preferably 0.2 mm thickness. The plastic layer is reinforced by a multi-ply, preferably two-ply, glass fiber fabric, which is so woven that the layers or plies of the fabric are interwoven or interlocked. The fabric is embedded in the plastic coating, before it is cured, for example by rolling it into the plastic coating. To assure good fitting of the inner wall against the outer wall, a vacuum is applied in the space formed by the projections or puckers of the sheet elements and the outer wall before the plastic coating has cured, and maintained until it is cured. The sheet or foil elements and the reinforced plastic will then form a laminate of high inherent stability with high bending and tensile strength, so that fissures are effectively avoided and the tank construction will be reliably tight and highly resistant to the formation of bulges and damage, for example due to dropped tools during installation, or inspection.

Title: Electrodeless plasma torch apparatus and methods for the dissociation of hazardous waste
Inventor: WONG ALFRED YIU-FAI
IPC: A62D101/40
Filed: 1992-08-14
Granted: 2003-01-21
Abstract: A system and method are provided for the non-thermal destruction of hazardous waste material using an electrodeless inductively coupled RF plasma torch (30). The waste material (26, 32) is combined with a controllable source of free electrons (34), and the RF plasma torch is used to excite the free electrons, raising their temperature to 3000 °C  or more. The electrons are maintained at this temperature for a sufficient time to enable the free electrons to dissociate the waste material as a re-sult of collisions and ultraviolet radiation generated in situ (60) by elec-tron-molecule collisions. The source of free electrons is preferably an in-ert gas such as argon, which may be used as both the waste material carrier gas and the torch gas.
Patent CA-2116885-C (CA)
Inventor: DAHLQVIST KARL THORE GORAN
IPC: D21D1/22
Filed: 1994-03-03
Granted: 1998-06-16
Abstract: Apparatus and method for the mechanical refining of high consistency lignocellulosic feed material in a frustoconical refining zone, by facilitating the backflow of steam generated in the refining zone through the upstream feed zone which, despite the backflow of steam, imparts outward force on the feed material sufficient for the material to enter the refining zone and pass therethrough, without blockage or flow interruption.  This is accomplished by providing, immediately upstream of the frustoconical refining zone (46), a hybrid feed/grinding zone (104), which acts on the wood chips with relatively high refining intensity at low refining power, so as to reduce the size of the material and outwardly convey the material by centrifugal force into the frustoconical refining zone against the backflowing steam, but without generating steam in the hybrid zone.  The hybrid zone receives chips from a feed screw (84) which preferably rotates at the same speed as the rotor (20) portion of the frustoconical refining zone and hybrid zone.  The feed screw is shaped (e.g., as a ribbon screw) so that the chip material is easily "handed-off" to the entry of the hybrid zone, while establishing an open channel (166) between the chip material and the shaft of the feed screw, for conveying backflowing steam away from the hybrid zone. First pressure control means (136) are provided in fluid communication with the backflow steam channel, for removing the backflowing steam from the refiner at a controlled pressure, thereby controlling the retention time of the material in the frustoconical refining zone (146).

Granted: 1999-10-05
Abstract: This apparatus (101) operates to discern temporal and spatial anomalies in the use of subscriber numbers in the cellular mobile telephone system, which anomalies are typically indicative of cloning of valid subscriber numbers. The detection of a bogus subscriber unit (B) is accomplished by recording the call origination and termination patterns associated with the subscriber number. The cloning detection apparatus (101) makes use of call origination data to identify concurrent call originations or receptions for a single subscriber number. Further analysis also includes a spatial analysis of successive call activity for a subscriber number. If two successive calls for a particular subscriber number are detected in a time interval that is too short to justify the geographic separation of the subscriber unit (B) for the two successive calls, then this apparatus identifies these two call connections as including one subscriber unit (B) having a cloned subscriber number,

Abstract: A guard structure for installation at the edge of a building roof eave to assist in shingling and reshingling employs a plurality of spaced roof cleats that are nailed to the roof, each having a hinge at its lower end with a hinge axis parallel to the eave. Each hinge connects the cleat to a respective vertical support member at a junction portion immediately adjacent to the eave. The portion of the support member below the eave or roof line engages with the building structure, e.g. the rafter tail or fascia board, usually through a pressure plate, and may carry a screw-threaded adjustment member for adjustment of the vertical attitude of the support member. The other portion of the support member has a lower outward upward inclined part carrying a toe board retainer member for an inclined toe board, and an upper vertical part carrying at least two vertically spaced back rail support members, as is usually required by building safety regulations. The toe board and the back rail support members form a safety structure for the roofer. Metal safety straps may be provided extending longitudinally beneath the toe boards to prevent catastrophic breakage if they should sag excessively. The upper vertical part may also be provided with a retainer for a vertical horizontally extending catch board; when such a catch board is provided it cooperates with the toe board to form a catch space to prevent debris falling from the structure to the ground and also provides an improved safety structure.
