Patent NO-179776-C (NO)
Inventor: COULAIT DAVID JOSEPH KENNETH
IPC: A61F13/49
Filed: 1993-03-04
Abstract: A disposable absorbent article, such as a diaper, having an improved tape fastener system is disclosed. The improved tape fastener system comprises a mechanical fastening means, initial adhesive securement means, and a reserve/protected adhesive securement means. The mechanical fastening means provide for effective side closure of the absorbent article, whereas the initial adhesive securement means provides a convenient initial disposal mechanism by which the absorbent article may be folded or rolled up into a configuration for disposal, secured in the disposal configuration, and thrown away. If the initial disposal adhesive becomes contaminated or insufficient for securing the absorbent article in its disposal configuration, the reserve/protected adhesive is available for use, with only minimal additional effort.

The apparatus also includes a pair of mating sleeves positioned in the interior chamber,  in spaced apart relationships,  each having a cylindrical mating  surface  which  sealingly  mates  against  the interior surface of the sealing sleeve and a projecting sleeve  receiving  cylindrical  surface.    The  sleeve receiving surfaces are juxtaposed opposite one another. An  elastomeric  boot  is positioned  over  the  sleeve receiving  surfaces  of  each mating sleeve to thereby extend  between  the  pair  of  sleeves  and  divide  the interior  chamber  into  an  interior  non-electrically conducting  fluid  retaining  region  and  an  exterior region.   An orifice is provided through the connector housing and the sealing sleeve to provide communication between the exterior region adjacent  the  elastomeric boot and the environment outside the connector.

Title: Process and apparatus for the dry removal of polluting material from gas streams
Inventor: EWAN THOMAS KENNY
IPC: B01D53/52
Filed: 1989-11-08
Granted: 2000-06-13
Abstract: A process for the removal of acidic gases from carrier gases employing a finely divided alkaline sorbent material is disclosed. The process includes, optionally, the step of conditioning the carrier gas to lower its temperature. The process comprises introducing a stream containing the alkaline sorbent material and mixing the alkaline sorbent material and the carrier gas, introducing a stream of vapor and liquid droplets and mixing the stream of vapor and liquid droplets with the stream of carrier gas containing the alkaline sorbent material. Thereafter a portion of the vapor is condensed and the alkaline sorbent material reacted with the acid gases to form products of reaction.      Finally, the products of reaction and the remaining alkaline sorbent material are separated from the carrier gas stream. Preferably, the alkaline sorbent material is calcium based, e.g., calcium hydroxide or calcium carbonate and the vapor and liquid droplets comprise low pressure steam and water, respectively.      The mixing process is facilitated by a free jet nozzle operated with a low pressure drop across the nozzle.      The separation step may be formed in a fabric filter (baghouse) or an electrostatic precipitator.

Granted: 1995-07-18
Abstract: An apparatus is disclosed for flipping over flexible and limp planar workpieces such as fabric. The apparatus includes a primary workpiece propeller having a cylindrical means for contacting the workpiece about a central rotating axis.  A slot of sufficient size to receive the workpiece is positioned in a vertical orientation beneath the primary propeller. The slot preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller.  The fabric is drawn into the slot by the rotation of the propeller and follows the contour of the flared open end of the slot .  The fabric enters into the slot until the trailing edge of the fabric is in contact with the primary propeller.  The trailing edge of the fabric is gripped by the propeller and thereby drawn to the opposite side of the flared opening of the slot and is subsequently pulled out of the slot.  The fabric has thereby been inverted so that the top of the fabric is now on the bottom.

Title: Semiconductor electric power conversion system
Inventor: BANDO AKIRA
IPC: H02H7/125
Filed: 1990-03-20
Granted: 1994-10-04
Abstract: Disclosed is an improved electric power conversion system comprising a multi-phase bridge circuit composed of semiconductors such as thyristors and an associated firing circuit.  It is so constructed that: if the AC input current Iac flowing in said bridge circuit is equal to or larger in value than the DC output current Idc flowing out of the bridge circuit, it will be decided that an inner defect or fault is caused, and possible expansion of inner defect will be prevented by disabling the firing circuit to extinguish said thyristors in the bridge circuit, and if the AC input current Iac is smaller than the DC output current Idc in value, the bridge is permitted to continue the operation of power conversion, thus eliminating unnecessary interruption which otherwise would be caused by exterior disturbances. Also, an improved electric power conversion system may be equipped with a device to prevent an adverse effect from being caused by abnormal rise of thyristors' temperature.

Abstract: ABSTRACT     First, a steel wire is continuously dipping in molten copper or molten copper alloy so that copper or copper alloy builds up and solidifies on the peripheral surface of said steel wire, thereby obtaining an initial copper-clad steel wire.  Then, the initial copper-clad steel wire is subjected a first cycle of hot rolling by a caliber roll.  The hot-rolled wire is dipped in molten copper or molten copper-alloy at least once so that copper or copper alloy builds up and solidifies thereon, thereby obtaining a final copper-clad steel wire.    The final copper-clad steel wire is hot-rolled at a temperature of 750 to 850°C and with a rolling ratio of 10 to 40%.  Then, the hot-rolled wire is cold-rolled with a reduction of area of 20% or more.  Thus, 75 to 90% of the cross sectional area of the obtained copper-clad steel trolley wire is occupied by the copper or copper alloy covering layer so that the electric conductivity of the trolley wire is very high as 80% IACS or more.  Moreover, the cast rod is hot-rolled so that the core and the covering layer are metallurgically bonded to each other, thereby obtaining a copper-clad steel trolley wire whose core and covering layer are firmly bonded.  Also, the hot-rolled wire is cold- rolled so that the trolley wire with a high strength is obtained.
