Patent NO-156955-C (NO)
Inventor: HAALAND PER
IPC: F16L17/02
Filed: 1983-06-20
Abstract: An annular gasket of a soft elastic material is fixed in a groove in a socket (14) which is to receive a pipe end (9). Attached to the annular leading edge (A) of the main gasket body relative to the pipe end (9) is a closed, annular hollow jacket (22) which during insertion of the pipe end (9) is entrained so as to form a double layer over the adjacent surface (4) of the main gasket body, the surface (4) being presented to the pipe end (9) by a sliding part (2) of the main gasket body. When fully inserted, the pipe end (9) compresses the main gasket body between the double layer formed by the jacket (22) and the socket (14).
Patent NO-158271-C (NO)
Inventor: KARLSSON LARS
IPC: F41H3/02
Filed: 1984-01-13
Abstract: The invention relates to a thermal camouflage comprising a strengthening layer (4), e.g. a woven material, on which a polyethylene film layer (1), metallized on one side, has been laminated with the aid of fusion adhesive (3). On lamination the surface is embossed such as to make it mat. Since the polyethylene is transparent for infrared, it has low self-radiation. By means of the metal layer (2) there is obtained radiation insulation so that the outer layer (1) is in a thermal equilibrium which is hardly affected, e.g. by a warm object which is covered with the material, and the outer layer has a low emission ability of about 0.6-0.8, depending on thickness and pigmentation. By applying further layers (5), patchy images may be obtained with infrared reproduction in the wavelength ranges of 3-5  mu m and 8-14  mu m.

Title: Cellular arrays for rapid molecular profiling
Inventor: KALLIONIEMI OLLI
IPC: G16B40/00
Filed: 1999-02-24
Granted: 2004-07-29
Abstract: A method is disclosed for rapid molecular profiling of tissue or other cellular specimens by placing a donor specimen in an assigned location in a recipient array, providing copies of the array, and performing a different biological analysis of each copy. In one embodiment, the copies of the array are formed by placing elongated specimens in a three dimensional matrix, and cutting sections from the matrix to form multiple copies of a two dimensional array that can then be subjected to the different biological analyses. Alternatively, the array can be formed from cell suspensions such that identical multiple copies of an array are formed, in which corresponding positions in the copies of the array have samples from the same or similar specimen. The results of the different biological analyses are compared to determine if there are correlations between the results of the different biological analyses at each assigned location. In some embodiments, the specimens may be tissue specimens from different tumors, which are subjected to multiple parallel molecular (including genetic and immunological) analyses. The results of the parallel analyses are then used to detect common molecular characteristics of the tumor type, which can subsequently be used in the diagnosis or treatment of the disease. The biological characteristics of the tissue can be correlated with clinical or other information, to detect characteristics associated with the tissue, such as susceptibility or resistance to particular types of drug treatment. Other examples of suitable tissues which can be placed in the matrix include tissue from transgenic or model organisms, or cellular suspensions (such as cytological preparations or specimens of liquid malignancies or cell lines).

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a method for positioning with precision a member displaced along a rail transversely with respect to the symetry axis of the head of said rail. According to this method, one emits through the head of the rail two ultrasound beams which are prati-cally perpendicular to the fishing plates of this rail. One receives the echoes of these beams reflected by the fishing plates. One forms a regulation or adjusting sig-nal which is function of the time difference between the emission and the reception of its echoe for each said two ultrasound beams and uses this regulating signal to elaborate a control signal for the transverse position-ing of the said member.

Abstract: Between a handle portion (10) and a batting portion 116) a relative rotational movement around the longi-tudinal axis (38) is possible. For this purpose a torsion-spring-element is incorporated in the handle (26) which effects a damping when the ball hits the string (14) or the frame (12) beside the longitudinal axis (38).          By the damping of the torsion movement an overload of the area of the forearm and of the elbow joint of the player is substantially avoided. (Figure 1)

Abstract: CONCRETE BLOCK FOR RETAINING WALLS Abstract of the Invention A concrete block particularly directed to the construction of retaining wall systems, characterized par-ticularly by a step back frontal surface which includes a frontal surface having a flat decoratable portion over a substantial vertical dimension thereof and tapered rear-wardly and vertically from such frontal surface to a top planar surface with an interlock area behind such surface to receive additional blocks thereon to create a wall. This interlock area provides a flat planar block locating surface for the positioning of a next vertical block and when the blocks are arranged in vertical relation on top of one another a step back frontal surface is provided. Combination drainage and tie-back anchor apertures are provided in the rear vertical surface of the block.  The block includes weight reducing passages vertically therethrough which also accommodate vertical tiers.  The block may include rearwardly and inwardly directed sides such that adjacent blocks are joined to form a curved frontal surface of the constructed wall.  The interlock of the blocks creates a strong barrier wall which affords an artistically con-ceived frontal surface.  The design of the blocks provides for a vertical and horizontal tying of the blocks through reinforcing bars or other means.

Inventor: GREENFIELD ROBERT S
IPC: A61P31/00
Filed: 1990-05-11
Granted: 1999-06-29
Abstract: The present invention relates to novel conjugates, methods for their production, pharmaceutical compositions and methods for delivering cytotoxic anthracyclines to a selected population of cells desired to be eliminated.  More particularly, the invention relates to anthracycline conjugates comprising at least one anthracycline molecule linked to a molecule that is reactive with a cell population to be eliminated.  According to one embodiment of the invention, the conjugate is comprised of an antibody reactive with a selected cell population, the antibody having a number of anthracycline molecules linked to its structure.  Each anthracycline molecule, having a keto group at the C-13 position, is conjugated to the antibody via a linker arm and is bound to that linker arm via an acid-sensitive acylhydrazone bond at the 13-keto position of the anthracycline.  A preferred embodiment of the invention relates to an adriamycin immunoconjugate wherein a 13-keto acylhydrazone bond is the site of the adriamycin attachment to the linker arm, the linker additionally containing a disulfide or thioether linkage as part of the antibody attachment to the immunoconjugate.  According to another embodiment of the invention, the conjugate is comprised of at least one anthracycline molecule conjugated via a linker arm to a ligand such as bombesin, epidermal growth factor or transferrin, the anthracycline being bound to the linker via an acid-sensitive acylhydrazone bond at the 13-keto position of the anthracycline.  In addition, novel anthracycline acylhydrazone derivatives are disclosed that are useful in the preparation of the conjugates of this invention.  The acid-sensitive hydrazone bond of the conjugates of this invention allows the release of free anthracycline from the conjugates in the acidic external or internal environment of the target cell.          The conjugates and methods of the invention are therefore useful in antibody- or ligand-mediated drug delivery systems for the preferential killing of a selected cell population in the treatment of diseases such as cancers and other tumors, non-cytocidal viral or other pathogenic infections, and autoimmune disorders.
