Abstract: An adhesive tape composition includes a polymer blend comprising at least one ethylene-propylene-diene terpolymer and at least one fully saturated adhesive-enhancing polymer miscible with said at least one ethylene-propylene-diene terpolymer. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber.     A method is also provided for covering roofs which includes the step of employing the adhesive tape composition.

Abstract: The carbon content in molten steel is adjusted to be a value not lower than 0.001%, and a thin steel strip is made from this molten steel using a twin drum type continuous casting apparatus by means of direct casting. The thus obtained slab is given a reduction of not lower than 10%.  The coagulated steel strip is cooled to a temperature not higher than the temperature determined by a function of the carbon content, cooling speed and ratio of reduction of in-line.  After that, the steel strip is reheated and then cooled again to a temperature not higher than the temperature determined by the function of the carbon content.  Then the cooled steel strip is coiled. In the above process, a metallic sheet, the surface of which is smooth and the metallic structure of which is fine, can be produced.

Abstract: Le dispositif d'équilibrage de charge comporte des circuits bobine de liaison couplés de manière inductive à des bobines de chauffage par induction qui sont connectées en parallèle aux bornes d'une source d'énergie. Un condensateur est connecté électriquement dans le circuit bobine de liaison. On modifie l'ampleur de la réactance couplée dans la bobine de chauffage. En modifiant le degré de couplage inductif de la bobine de liaison à la bobine de chauffage ou en modifiant la capacité, soit en utilisant un condensateur variable ou en commutant entre différents condensateurs. Ainsi, le courant dans la bobine de chauffage correspondante peut être modifié, ce qui permet de régler le chauffage de la pièce à travailler. Le système résultant est ainsi efficace, du fait qu'une seule bobine et non pas des bobines multiples montées en série parallèle est utilisée. Cet aspect peut être encore accentué lorsqu'un câble de Litz est utilisé dans la construction de la bobine. De plus, ledit système est compatible avec une commande active.

Abstract: A video-scrambling system induces a random wobble i.e., time shifting, in the location of active portion of the video frame, without affecting the horizontal sync signal and colorburst in each video line, thus providing both security and concealment.  The security is enhanced by filling in the gap between the nominal beginning of active video and the actual beginning of active video with a synthesized video signal which replicates the adjacent active video using a digitally generated filling pattern. Also, a random noise overlay further conceals the location of the gap.  Additional concealment is provided by wiggling in time the location of the horizontal sync signal using one or two frequencies and also by randomly altering the location of the vertical sync signal.  The NTSC digital encoding in accordance with the invention is simplified by using only two channels, chrominance and luminance, and by a heterodyne circuit for chrominance stability.  NTSC encoding is enhanced by providing detail normally lost, by use of the chroma channel.  Additionally, a non-standard video signal may be provided with a portion of the colorburst on the front porch of the horizontal blanking, thus allowing use of a relatively simple decoder.

Title: Parathyroid hormone analogues for the treatment of osteoporosis
Inventor: WILLICK GORDON E
IPC: A61P19/10
Filed: 1997-08-01
Granted: 2007-10-30
Abstract: This invention describes analogues of human parathyroid hormone which have increased activities in bone restoration, and increased bioavailabilities. The peptides described are derivatives of hPTH-(1-31) which are cyclized for example, by formation of Lactams between either Glu22 and Lys26 or Lys26 and Asp30. In addition, the natural Lys27 may be substituted by either a Leu or other hydrophobic residues, such as Ile, norleucine, Met, Val, Ala, Trp, or Phe. Typically, these analogues have enhanced abilities to stimulate adenylyl cyclase in rat osteosarcoma cells, and show increased activities in bone restoration, using the ovariectomized rat model. The analogues also show enhanced activities and bioavailabilities, as demonstrated by their hypotensive effects in the rat. An assay which correlates hypotensive activity with osteogenic activity is also described.
