Title: Apparatus and method for supporting concrete beams, walls and the like
Inventor: ISLES TIMOTHY J
IPC: E04G9/10
Filed: 1998-04-30
Abstract: A completely closed and reinforced box-like structure for forming a void area in a concrete formation is constructed of a flat sheet that is scored with a plurality of parallel crease lines and features a side edge reinforcing panel. The reinforcing panel has a plurality of slots thereon. A plurality of interior and end pieces are slit scored so that they may be folded to provide interior and end support units. The support units define a plurality of spaced apart partitions having a plurality of slots and flat support surfaces thereon. The structure is assembled by initially folding the side edge reinforcing panel into a position generally normal to the flat sheet to define a longitudinal rib. The support units are then attached to the longitudinal rib by registering the slots in the partitions in interlocking relationship with corresponding slots on the rib. The support units are then rolled over to fold remaining panels of the sheet along the crease lines in wrapping relation around the support units and thus, the flat support surfaces. As a result, an enclosure with an interior chamber is defined wherein each of the support partitions substantially fills the cross-sectional area of the interior chamber and the flat support surfaces abut the enclosure. A pair of end panels cover the enclosure end openings so that the box-like structure is completely closed.

Title: Back panel for a plasma display device
Inventor: HOZER LESZEK
IPC: H01J9/20
Filed: 1998-12-16
Abstract: A plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. Barrier ribs are formed on the back panel by embossing the green tape before cofiring the bonded assembly. The green tape is embossed using pulsed pressure and an embossing tool that is formed by assembling embossing members and spacing members in compression. The embossing tool further includes elastic spacers mounted outside of the embossing tool and in a position such that the elastic spacers are held in compression during the embossing operation to aid in releasing the embossed green tape from the embossing tool after the embossing operation.

Inventor: SUH DONG-HACK
IPC: C07D207/452
Filed: 1998-12-23
Abstract: A bis(dialkylmaleimide) derivative and a polyetherimide for optical communications, the polyetherimide formed therefrom. The polyetherimde has a high refractive index, so that when using such polyetherimide as a material for a core of an optical fiber, the range of the materials that can be selected for the cladding becomes wide. Also, a coating property and adhesion to a substrate are improved, thereby providing a good film forming property and thermal stability. Also, because the polyetherimide can minimize optical loss at a near infrared wavelength range, the polyetherimide is very useful as an optical material in the optical communications field adopting the light of near infrared wavelength.

Title: Imaging apparatus having a large sensing area
Inventor: SCHULMAN TOM GUNNAR
IPC: H01L27/146
Filed: 1997-07-03
Abstract: Imaging apparatus includes an imaging support and a number of imaging device tiles (56, 58). Each tile includes an imaging device having an imaging surface and has a non-active region (50) at or adjacent an edge of the tile. The imaging device on a tile mounted on said support is tilted such that a part of the imaging surface (60) of one tile at least partially overlies the non-active region of another tile, thereby providing substantially continuous imaging in a first direction. The space between tiles in the direction orthogonal to the first direction is minimsed by ensuring that the width of the imaging surface of a detector layer of the imaging device is the same as or greater than that of a readout layer of the imaging device and that of a mount for the imaging device.

Abstract: The synchronous serial bus (13) between a main processing unit (10) and a peripheral unit (12) includes a data line (BDA) and a clock line (BCL). Strobe pulses presented by the main processing unit (10) on the data line while it holds the clock line at a given logic level characterise transfer cycles on the bus (13). The main processing unit (10) can thus run write or read cycles in registers of an interface (16) of the peripheral unit (12). A  direct transfer mode, wherein the strobe pulse is transmitted at the beginning of the cycle without specifying an address, is provided to enable the main processing unit (10) to have a fast access to certain locations previously specified. The data and clock lines (BDA,BCL) of the bus (13) may be shared with those of another synchronous bus (11).

Title: Method and device for connecting a data processing system central unit to a redundancy data storage sub-system
Inventor: PINSON DENIS
IPC: G06F11/22
Filed: 1998-04-23
Abstract: The invention concerns a system comprising a central unit (CPU) associated with one or several input-output control units (Ctl¿1?-Ctl¿4?) and a redundancy disk sub-system (MD), divided into logical units and under the control of two redundant disk controllers (SP-A, SP-B). These are attached to the input-output controller(s) by buses likewise redundant. One first part of the logical units is assigned to the first disk controller (SP-A) and the other part to the second disk controller (SP-B). When a logical unit, assigned to the first disk controller (SP-A) is accessed, the state of the second disk controller (SP-B) is monitored by the backup path. If a breakdown of the second disk controller (SP-B) is detected, all the logical units are toggled on to the first (SP-A) and are assigned thereto. A crippled mode is initiated and access to resources is carried out by the backup path. The invention is applicable to data processing.

Abstract: A method of applying a smooth thin waterproof coating on engineered particleboards including oriented strand boards, thereby permitting the use of such boards for applications wherein the boards are exposed to moisture, including, for example, foundation forms, roof sheathing, basement walls, etc. The method of this invention includes applying a thin liquid cementitious coating on a surface of an engineered particleboard having a moisture content preferably less than three percent, wherein the cementitious coating fills the interstices between the particles and coats the surface. The cementitious coating is then dried and the surface is abraded to receive a thin liquid curable polyurethane coating over the cementitious coating. Finally, the exposed surface of the polyurethane coating is heated to remove surface imperfections and cure the polyurethane coating. In the preferred method, the liquid polyurethane coating is heated and cured by applying an open flame to the surface of the liquid polyurethane coating which removes surface imperfections, such as bubbles, and simultaneously cures the coating.

Patent CA-2273514-A1 (CA)
Inventor: GHERSON PAUL
IPC: G01N1/00
Filed: 1999-06-02
Abstract: A blood clot detector includes a pressure transducer on an aspiration line to provide output voltage data to a microprocessor corresponding to the vacuum level during aspiration. The microprocessor integrates the vacuum readings over time during the aspiration cycle to provide a pressure integral for each test sample aspiration. A pressure integral is determined for an unclotted aspiration and used as a reference for comparison with the pressure integrals of each test sample aspiration to determine whether a blood clot has interfered with the test sample aspiration. A valve is provided across an analytical line and an aspiration line to provide selective communication between the aspiration line and the analytical line or to prevent such communication. Communication between the aspiration line and the analytical line permits transfer of a test sample from the aspiration line to the analytical line if the test sample is considered acceptable for sample analysis. Acceptability of the test sample for analysis is based upon a predetermined difference between the reference pressure integral and each test sample pressure integral.
