Title: Cylinder surface finish pattern and an apparatus and method for finishing the surface of a cylindrical workpiece
Inventor: KAPASKY STANLEY
IPC: B24B21/02
Filed: 1994-12-06
Abstract: A surface finishing apparatus and process provides for finishing and removing imperfections from the surface of a cylindrical workpiece, such as a gravure cylinder, using a polishing pad with an abrasive surface that is driven over the surface of the cylinder. The finish pattern achieved by the process and apparatus is a crisscrossing or overlapping series of curved lines with spaces therebetween, which gives the cylinder surface a roughness that is substantially the same in the direction of the axis and the radius of the cylinder. The finish is applied in the direction of the web, provides excellent control of the movement of the web over the cylinder, increases cylinder life, reduces doctor blade wear, and provides improved clarity and quality of print using the finished cylinder. The time needed to finish a cylinder is reduced over known methods, and the apparatus and process provided are cost and time effective.

Patent CA-2143144-A1 (CA)
Inventor: EVANS JAMES G
IPC: G01S13/88
Filed: 1995-02-22
Abstract: A modulated backscatter communication system (e.g., an Electronic Shelf Label (ESL) system) includes a central node (e.g., a ceiling node) and one or more remote nodes (e.g., ESL tags). The central node transmits a downlink radio signal which is reflectively modulated at a remote node to produce a modulated reflected radio signal. At the remote node, a precise-frequency subcarrier signal is modulated with an uplink information signal to produce a modulated signal which is used to produce the modulated reflected radio signal. At the central node, the modulated reflected radio signal is received, detected and narrowband filtered to obtain the modulated subcarrier signal which is then demodulated to obtain the uplink information signal, with great immunity to close to carrier downlink radio noise and fluorescent light backscatter interference.

Title: A Stamp and a Process of Producing a Printing Plate for a Stamp
Inventor: ANDO YOICHI
IPC: B41C1/055
Filed: 1994-09-30
Abstract: The present invention is to provide a stamp as well as to a process of producing a printing plate for a stamp which is made of a sponge having open cells thereby allowing repeated impressing operations to be done without supplying stamp ink for a long time.    A producing process of a printing plate for a stamp of the present invention includes the steps of: fitting a heat-fusing ink sheet or a heat-generating plate containing a heat-generating material, over the surface of a stamp-piece having open cells therein; making a liquid substance soak a manuscript having characters, patters etc., represented by non-applied areas of recording material and applied areas of recording material; placing the manuscript over the top in such a manner that the impress original image may appear to be a mirror image; and irradiating the manuscript from thereabove with light so as to cause light passing through the non-applied areas of recording material to increase the temperature of the heat-generating material at corresponding sites to the non-applied areas of recording material whereby the generated heat of the heat-generating material corresponding to the non-applied portion of recording material fuses the surface part of the stamp-piece, or the heat-fusing ink of the heat-fusing ink sheet is fused to permeate the surface layer as well as to fuse the surface layer, thereby forming non-oozing areas of stamp ink while the stamp surface portion corresponding to the applied areas of recording material is not fused, thus forming oozing areas of stamp ink.
Patent CA-2150980-A1 (CA)
Title: Safety container for dangerous products
Inventor: LAPIERRE MAURICE
IPC: B65D50/10
Filed: 1995-06-05
Abstract: The cylindrical container is closable by a closure cap. The container mouth includes two axially spaced, radially outwardly depending first and second flanges. The first flange, closest to the mouth, is V-shape, and is adapted to fit inside a shallow complementary groove made on the radially inward wall of the cap rim. The second flange is L-shape, defining an annular stop that prevents an identification label from moving against the container body beyond the second flange and toward the container mouth, so as to prevent accidental overlap of the label over the cap rim. A downwardly-pointing arrow is carried by a section of the cap rim, and an upwardly pointing arrow notch is made about the second flange, so that by rotating cap to bring both cap arrow and container arrow notch in respective register, the safety cap can be released from the container mouth.

Title: Connection for two-part handle
Inventor: WITKOWSKI WILLIAM R
IPC: B25G3/04
Filed: 1995-06-23
Abstract: An elongated handle has a proximal elongated plastic section joined to a distal metal section. The plastic section is provided with a plurality of flexible, longitudinally ribbed tabs extending outwardly thereof, at least one of which has an outwardly extending cross longitudinal rib. The distal section has internal longitudinal grooves that receive the longitudinal ribs, and also has a circumferential groove formed in its internal surface for engaging the cross longitudinal rib.

Inventor: FUNG STEVEN
IPC: C12Q1/70
Filed: 1995-09-22
Abstract: Method and kits are provided for detecting one or more target nucleic acids. A first oligonucleotide having a 3' amino group and a second oligonucleotide having a 5' phosphate group are annealed to a contiguous complementary region of a target nucleic acid. Whenever the 3' terminal nucleotides of the first oligonucleotide and the 5' nucleotides of the second oligonucleotide are complementary to the opposing nucleotides on the target nucleic acid, a nucleic acid ligase ligates the first and second oligonucleotides via the formation of a phosphoramidate linkage. The presence of the target nucleic acid is determined by detection of the ligated first and second oligonucleotides.

Title: Outdoor structure such as gate post, gate wing or fence
Inventor: SUGIYAMA SHIGEYUKI
IPC: B29L31/10
Filed: 1995-12-29
Abstract: The invention aims to make outdoor structure such as gate post suitable for mass production by achieving weight reduction of such structure so that the structure can be manually  transported,  installed,  on  one  hand,  and by facilitating adhesive fixation of artificial stones,  on the other hand.    A substrate 10 of a gate post A is molded from foam plastics  and  a  nail  21  is  partily  embedded  in  each artificial stone 20 during a process of molding this stone 20 so that the nail 21 may partily project out from  the rear surface of the artificial stone 20. Adhesive mortar is applied to the substrate 10 and/or the artificial stone 20 and then the artificial stone 20 is pressed against the substrate  10  so  that  the  nail  21  may  penetrate  the substrate 10 and thereby the artificial stone 20 may be adhesively  fixed.  In  this  manner,  the  gate  post  A  is effectively weight-reduced and the nail 21 is held by the substrate 10 under an elasticity of the foamed plastics until the adhesive mortar 23 is set. The artificial stone 20 is prevented by such provisional fixation from scaling off or falling off and there by production is facilitated.
