Title: Closure means for a bottle filled with a fluid
Inventor: MABILLE PIERRE
IPC: B65D47/26
Filed: 1987-11-17
Granted: 1992-06-09
Abstract: Abstract A closure means for a bottle filled with a fluid comprises at least two closure disks that are each provided with at least one discharge opening at a common off-center posi-tion so that only in a singular relatively rotated posi-tion of these two disks a discharge of the bottled fluid will be made possible. This relatively rotated position is obtained by means of a fitting which may be fastened to the bottleneck through a turn-lock fastener and which has at least one discharge tube at a corresponding off-center position and interacting with the discharge open-ing of the one closure disk to rotate the same into the singular relative rotated position in which the dischar-ge tube as well will be axially aligned with the dis-charge openings of the two closure disks. A third closure disk is preferably provided for presenting with a con-centric guidung slot a first working element of a bayo-net-type fastener the second working element of which is presented by the head portion of a coordinated discharge tube of a fitting.

Abstract: TITLE          FORECASTING THE RISK OF SCLEROTINIA                   STEM ROT IN CROPS                      INVENTORS        Robin A.A. Morrall T. Kelly Turkington Richard K. Gugel Sheldon V. Rude ABSTRACT OF THE DISCLOSURE         Sclerotinia stem rot, caused by the fungus Sclero-tinia sclerotiorum (Lib.) de Bary, is a major disease of rapeseed (canola) in western Canada and many other parts of the world.  Significant yield losses result from severe crop infestations.  A method of stem rot disease forecasting is disclosed.  The method is based on the relationship dis-covered between infestation of top plant parts with spores of the fungus at early bloom and subsequent disease inci-dence.  Also disclosed are media compositions, which facilitate rapid growth of S. sclerotiorum from plant parts under non-sterile conditions and thereby permit detection of the fungus.  This forecasting system allows improved disease risk assessment in advance of the need for spraying against sclerotinia stem rot.
Patent CA-1287527-C (CA)

IPC: H01B13/00
Filed: 1988-03-29
Granted: 1991-08-13
Abstract: Abstract:     A superconductive thin film is made by a procedure as follows:  in a vacuum vessel having an internal pressure maintained at least as low as 10-2 torr, each metal of the component elements of the superconductive thin film is charged into a crucible to be heated.  The resulting evaporated metallic element is spouted from the crucible as a cluster beam.  Each spouted metallic stream is ionized and accelerated by an electric field and impinges on a substrate.   Oxygen gas is directed towards the substrate.  The heating of the crucibles is so controlled that the amounts of the respective metallic streams are in accordance with a predetermined mole ratio.  In this way there is formed on the substrate a superconductive thin film having improved properties of adhesion, and the manufacturing procedure is simplified.

Title: Direct cast strip thickness control
Inventor: BARTLETT EDWIN S
IPC: B22D11/06
Filed: 1988-04-13
Granted: 1993-02-09
Abstract: Abstract Metal  strip  3  may  be  cast  directly  from molten metal in an open tundish 2 onto a chill roll 1.   Strip thickness  is  controlled  by  contouring  the  tundish  lip 14 with an offset 10 near the casting wheel.   This can be  used  remedially  to  offset  the  natural  tendency  for the  strip  to  be  thicker  near  the  edges,  which  is undesirable for cold rolling, or it may be used creatively to produce contoured strip.

Title: Coded modulation communication system
Inventor: SAITO YOICHI
IPC: H03M13/25
Filed: 1989-06-23
Granted: 1992-03-10
Abstract: TITLE OF THE INVENTION Coded Modulation Communication System ABSTRACT OF THE DISCLOSURE     In Trellis coded modulation system in which an input digital  signal  in  parallel  form  is  encoded  by  a convolutional encoder which adds an additional bit to the input digital signal for error correction purpose, and a mapping circuit designates amplitude and phase for each symbol  for QAM signal,  the number of parallel bits at output of said convolutional encoder is the same as the number of parallel bits of an input digital signal. An input digital signal is first rate converted so that m+n bits in every T period is converted to m bits in every T' period,  where T'=(m/(m+n))?T.  The convolutional encoder adds n number of bits so that the total number of parallel bits is m+n, which is applied to the mapping circuit. In a receive side, a receive signal having m+n bits in every T' period  is  decoded through an error  correction decoder which  provides  m  bits  in  every  T'  period,  then,  the decoded signal is rate converted to m+n bits in every T period. So, the number of parallel bits does not increase in spite of convolutional encoding, but a transmission rate is a little increased. The coding gain in the present invention is improved since the number of levels of the QAM signal is not increased although the bandwidth of the signal is a little increased because of the higher clock rate.
