Title: Agonist peptide dimers
Inventor: JOHNSON DANA L
IPC: A61K38/28
Filed: 1996-06-06
Abstract: The present invention is directed to the dimerization of agonists and antagonists of cell surface receptors and particularly to peptide dimers which behave as cell surface receptor agonists in their dimeric form. Such receptors belong to the dimerization-mediated activation class often observed among receptors for growth and differentiation factors. The agonists of this class of receptors is understood to effect dimerization of the receptor and thus signal initiation. The present invention exemplifies dimers of erythropoietin (EPO) agonists and antagonists comprising a core amino acid sequence of X3X4X5GPX6TWX7X8 (SEQ ID NO: 1) wherein each amino acid is indicated by standard one letter abbreviation; X3 can be C, A, .alpha.-amino-.gamma.-bromobutyric acid or Hoc; X4 can be R, H, L or W; X5 can be M, F, or I; X6 is idependently selected from any one of the 20 genetically coded L-amino acids or the stereoisomeric D-amino acids; X7 can be D, E, I, L or V; and X8 can be C, A, .alpha.-amino-.gamma.-bromobutyric acid or Hoc, provided that either X3 or X8 is C or Hoc.

Abstract: The present invention relates to an indexed storage cradle system for compact discs comprising a series of storage cradles rotatably mounted in parallel in a housing. Each cradle consists of a base having generally parallel vertically upstanding side walls, a rear wall and a vertical upstanding front wall. One of said side walls is higher than the other to act as a guide when inserting the disc into the slot formed between the two side walls. Means are provided on each of said side walls to keep the disc centered when fully inserted into the cradle. The top of the front wall of each cradle is provided with a cutout portion, and a tab is provided either on the bottom or the top of said cutout to facilitate pulling down the cradle and the location of the tab alternates on adjacent cradles to minimize the chance of inadvertently pulling down the adjacent cradle.

Title: Improved barstar gene
Inventor: WILLIAMS MARK
IPC: C12N15/55
Filed: 1997-09-01
Abstract: Improved barstar DNAs, such as synthetic barstar DNAs, produce high amounts of barstar protein in eucaryotic cells, particularly in plant cells, and especially in stamen cells such as tapetum cells. Synthetic barstar DNAs have less than 40 % A and T nucleotides. Other improved barstar DNAs encode improved barstar proteins which have an N-terminus which starts with Met-Xaa wherein Xaa is Alanine, Valine, Glycine, Aspartic acid or Glutamic acid. Plan cells and plants contain the improved barstar DNAs and/or express the improved barstar protein.
Patent CA-2238034-A1 (CA)
Title: Supported solid superacid catalysts and method for making them
Inventor: HU JIANLI
IPC: B01J27/057
Filed: 1996-11-18
Abstract: This invention provides supported solid superacid catalysts composed of anion-modified oxides/oxyhydroxides of Group IV metals such as hafnium (Hf), tin (Sn), titanium (Ti) or zirconium (Zr), precipitated onto a metal oxide support such as alumina, silica or mixtures thereof having initial surface area of 100-500 m2/gm, and is anion modified by addition of molybdate (MoO4), phosphate (PO4), selenate (SeO4), sulfate (SO4), or tungstate (WO4). The catalyst further includes an active promoter base metal such as Co, Ni and Pd or a noble metal such as Pt, Rh, and Ru to improve the catalyst stability against deactivation. These supported solid superacid catalysts are prepared by precipitation of hydroxides of Group IV metal onto the support material, followed by the anion-treatment, addition of the stabilizing promoter metal, and calcination at 500-650 ~C temperature. Typical supported solid superacid catalysts have a composition of 70-90 wt.% support material, 5-20 wt.% active transition metal oxide, 4-8 wt.% of the anionic group, and 0.05-5 wt.% of the active stabilizing base or noble promoter metal additive. The resulting catalysts have high final surface areas of 100-450 m2/gm, and provide high catalytic activity for various alkylation and hydrocarbon conversion reactions, such as alkylation of refinery gas for producing high-octane gasoline, cracking and hydroisomerization of long chain paraffins, and conversion of waste plastics and low quality oils waxes to produce value-added lubricating oils and chemicals.

Patent CA-2240301-A1 (CA)
Inventor: CARR DAVID WARD
IPC: H01J23/065
Filed: 1998-06-11
Abstract: A grid for use in a linear electron beam tube such as an IOT or TWT includes a grid section 3 and a mounting flange 4 between which is included an accommodation portion 5. During use, the grid section 3 becomes hot and consequently expands but the mounting flange 4 remains relatively cool being connected to a relatively massive structure. Thin flexible strips 8 of the accommodation portion 5 permit relative movement between the mounting flange 4 and the grid section 3 due to differential thermal expansion, thus minimising distortion to the grid section which might otherwise occur if it were connected directly to the mounting flange 4 and hence fixed in its outer diameter length.

Title: Optical demultiplexer filter system to eliminate cross-talk side-lobes
Inventor: SPECTOR MAGALY
IPC: H04B10/291
Filed: 1999-02-23
Abstract: Optical amplifiers are typically disposed along the transmission path of an optical system. If a large number of optical amplifiers, e.g., eight, are so disposed, then it is likely that an appreciable level of so-called power divergence will occur among the optical signals forming a composite optical signal that traverses the path. Disadvantageously, when the composite signal is received at a destination and demultiplexed, a number of the demultiplexed optical signals will contain components of the other demultiplexed optical signals as a result of such power divergence. This problem is readily handled using a facility which greatly suppresses such components in a demultiplexed optical signal.

Abstract: Le VFI~A, une veste de sécurité aquatique qui à été développé dans un centre de réadaptation, spécifiquement pour une clientèle multi-handicapée ou en perte d'autonomie. Au début du service de développement en piscine, l'utilisation des aides flottantes disponibles à l'époque sur le marché, ne correspondaient pas aux besoins de stabilité et de flottaison. Le Vêtement de Flottaison Individuel Adapté repousse les limites du chavirement ce qui en fait un veste très sécuritaire. C'est la position horizontale sur le dos que le VFI~A favorise. Il permet d'obtenir une sensation de flotter dans les nuages et d'oublier le soutien par les sangles. L'eau supporte le corps et le VFI~A le stabilise. En effet, plus le corps est à l'horizontal, plus il est en mesure de flotter par lui-même. Le VFI~A devient un outil de stabilisation plus que de flottaison... Parfait pour la relaxation et l'application de massages de manière sécuritaire.
