Patent NO-172409-C (NO)
Inventor: GSCHWEND PETER
IPC: F16B19/14
Filed: 1989-12-20
Abstract: To place fastening members (5) in receiving materials (1) such as concrete, rock and the like, the fastening members (5) are driven through the base (2b) of a blind hole (2) made beforehand in the receiving material (1). In the process, the fastening member (5) penetrates through a sleeve (3) inserted into the blind hole (2) and restrains this sleeve (3) under radial expansion in the blind hole (2). Anchorage of the fastening member (5) is thereby achieved both in the receiving material (1) by the area on the side of the drive-in direction and with the area passing through the sleeve (3).

Abstract: A method and apparatus in a drying section of a paper making machine wherein a so-called single-wire draw is applied and wherein blow boxes (20) are used, which are intended to prevent phenomena that disturb the mutual support contact between the web (W) and the drying wire (12).  The blow boxes (20) extend across the entire width of the web (W), and they communicate with members (17, 18, 21, 22) that supply blow air, and they are provided with at least two nozzle slots (13, 14) transverse to the running and longitudinal direction of the web (W) as well as with a carrier face (16) between said nozzle slots.  Negative pressure is produced in the space (A-) defined by the carrier face (16) and the drying wire (12) by means of the ejection and prevention effects of the air jets (F1, F2) blown through the nozzle slots (13,14).  In order to speed the threading of the web (W), in the blow boxes (20) the blow sections (24 k+l...24 N) that remain outside the transverse area (A) of the leader band (R) are closed.  The blowing, which has thereby been intensified, is applied through both of the opposite nozzles (13, 14) of the blow boxes (20) in connection with the threading only within  the area (A) comprising the width (LR) of the leader band (R).

Title: Method and apparatus for flexible and optimal telephone call acceptance and routing
Inventor: CARLSON DAVID GLENN
IPC: H04M1/665
Filed: 1992-01-06
Granted: 1996-04-09
Abstract: A  telephone  call  is  made  by  a  calling party.  The telephone call is routed through a telephone network to a piece  of  terminal  equipment.   The  terminal  equipment analyzes  call  information  associated  with  the telephone call.  The call information is divided into separate call attributes,  such as  calling telephone  number  and called telephone number.  One or more number lists, stored in the terminal equipment, are then searched to see if they contain an entry that matches the call attributes.   If a match is not found, the call is rejected.  If one or more matches is found, the call is routed as specified by the number list entry having the most optimal match.  The number lists can be easily user-modified.

Patent CA-2067211-C (CA)
Inventor: SAKURAI KATSUKIYO
IPC: C08B37/00
Filed: 1991-07-24
Granted: 2004-06-15
Abstract: This invention relates to compounds prepared by linking glycosaminoglycan to phospholipid or lipid, which are expected to exert a pharmacological effect for inhibiting metastasis because of their excellent function to inhibit adhesion of cancer cells to blood vessel endothelial cells and extracellular matrix. This phospholipid- or lipid-linked glycosaminoglycan can be produced for example by: cleaving and oxidizing reducing terminal group of glycosaminoglycan, and allow-ing an aldehyde group or a lactone compound of the thus-formed derivative or a carboxyl group in the glycos-aminoglycan chain to react with a primary amino group of a phospholipid; or linking a glycosaminoglycan deriva-tive to a phospholipid or a lipid by allowing a primary amino group of the derivative to react with a carboxyl group of the phospholipid or lipid. This phospholipid-or lipid-linked glycosaminoglycan is useful as a metastasis inhibitor because it has no toxicity.

Title: Method of counting particles
Inventor: ASANO KAORU
IPC: G06M11/00
Filed: 1992-06-03
Granted: 1998-06-09
Abstract: A method of seeking the number of particles of each kind in a group of particles in which plural kinds of particles are intermixed, by measuring, for example, two kinds of properties of each particle by a suitable method or device, plotting each particle on a rectangular co-ordinate system using the measured properties as its X and Y co-ordinates to obtain a distribution diagram, drafting boundaries to partition the distribution into clusters of the respective kinds and counting the number of particles within the boundary of each cluster, which, especially, even when the clusters of the respective particles are mutually overlapping, can reduce any deviation of the count of particles from its true value as much as possible by defining an optimum boundary.  In this method, a center of gravity of each cluster is determined, a degree of attribution of each particle to each cluster is calculated based upon a distance of each particle from the center of gravity and the number of particles belonging to each cluster is counted in consideration of the degree of attribution.
