Abstract: In a key distribution system comprising a first subsystem (11), a second subsystem (12), and a public file (13), the first subsystem transmits distribution information (IDA, YA) to the second subsystem via a communication channel (16).  The first subsystem (11) comprises a reading unit (22) for accessing the public file by reception identification information (IDB) inputted from an input unit (21) to read reception public information (XB).  A first cipher key generator (28) generates a first cipher key (KA) by applying a first predetermined transformation on the reception public information and the reception identification information on the basis of first and second constants (n, t), and a random number (r).  A distribution code generator (29) generates a key distribution code (YA) by applying a second predetermined transformation on transmission public information (XA) and a third constant (?) on the basis of the first constant, first secret information (rA), and the random number.  The second subsystem comprises a second cipher key generator (35) for generating a second cipher key (KB) by applying a third predetermined transformation on the key distribution code and the transmission identification information on the basis of the first and the second constants and second secret information (rB).  The second cipher key coincides with the first cipher key.

Abstract: A method and apparatus for profiling the bed of a furnace involves the production of a digital image of the bed and background.  The digital image is processed to determine transitions in the image which correspond to transitions between the bed and background and thereby to the boundary of the bed.  Bed characteristics, such as the bed profile, the bed height, the slope of the bed and the volume of the bed are determined from the processed image. The image may be displayed for use in controlling the performance of a furnace.  In addition, the determined bed characteristics may be compared with reference bed characteristics, with the differences being displayed, used in controlling the operation of the furnace, or in activating an indicator, such as an alarm, in the event the reference and determined bed characteristics differ by a threshold amount.

Abstract: PR?CIS Mon invention est un procédé et un appareillage qui utilisent la force gravitationnelle pour produire une énergie utilisable. Elle se rapporte au domaine des moteurs sans combustion. Dans un appareil, dit en "U", étanche, composé de deux sections principales communicantes, grâce au présent procédé, une des sections a une surface plus élevé que l'autre ce qui permet d'élever des poids de la surface basse à la surface haute et d'en capter l'énergie gravitationnelle par un appareillage qui utilise leur pesanteur à leur descente. Le procédé consiste en l'utilisation de deux liquides non miscibles et de densité différentes. Une section contient le liquide plus léger qui y est retenu dans une haute colonne par le liquide plus dense qui occupe la section basse et de grande surface. Dans le présent mode de réalisation, des (poids-flottants) objets solides de densité plus faible que celle de chacun des deux liquides, sont introduits dans la partie basse. Au moyen d'un poussoir hydraulique, ils sont dirigés vers la section au liquide moins dense, de là ils flottent vers la surface où ils sont cueillis par un cueilleur qui les soulève et les dirigent vers une chaîne sans fin. Une chaîne sans fin capte les poids-flottants qui passent de cette hauteur vers le bas pour être réintroduits près de la base du système. L'énergie est produite par la pesanteur des poids-flottants qui passent d'une plus grande à une plus faible hauteur, cette énergie qui autrement serait dissipé en chaleur à l'impact s'ils tombaient en chute libre, est transférée à la chaîne sans fin qui à son tour la communique à une roue qui actionne un alternateur électrique, un compresseur, une pompe ou une autre mécanique qui utilise ou transforme l'énergie reçue. J'ai donné à mon invention le nom de Cycloro.

Abstract: IN THE CANADIAN PATENT & TRADEMARK OFFICE            TITLE :       PROCESS   AND   DEVICE   PROVIDING   TIGHTENED               OPERATIONAL SAFETY  FOR  UNDERGROUND  LIQUEFIED GAS STORAGE            IN THE NAME OF : Jean-Marie DUFOURNEAUD            ASSIGNEE : Jean-Marie DUFOURNEAUD                ABSTRACT OF THE DISCLOSURE      A  safety    device  is  provided  for  completely sealing off an underground liquified gas store when a dangerous situation arises, whereby all links between the storage cavity and the surface, including the vent link between the gas phase  and  the  surface can be closed  off  by  forming water  plugs  in  the  storage cavity. The water plugs are created automatically from existing reserves of water in said underground cavity. Maximum overall safety is achieved by not installing any important equipment in the underground store,  by standardizing all links other than the vent link, and by minimizing the number of functional links required. Every  standard  link  connects  the  gaseous  or  liquid phase of the gas to the surface via a side tube (e.g., 22) running downwards into a well (24) containing water linked to the main tube  (21)  which returns to the surface. The end of the main tube comprises a shut-off valve (23) which causes the sealing water plug to be formed in both tubes  (22 and 21) once it is opened automatically or deliberately via an external signal.

Title: Method and apparatus for an increased pulse repetition rate for a cw pumped laser
Inventor: LONG DAVID C
IPC: H01S3/06
Filed: 1992-08-27
Abstract: METHOD AND APPARATUS FOR AN INCREASED PULSE    REPETITION RATE FOR A CW PUMPED LASER     ABSTRACT OF THE DISCLOSURE      A solid state lasing rod is spun on its long axis. The rod is pumped with photons while it spins.  The rod is greater in diameter than the aperture.   The rod is aligned off-center from the center of the aperture so that different portions of the rod are exposed to the aperture for lasing.  The repetition rate of the lasing of the laser is increased because as the rod spins, the area of the rod that is not lasing is being charged.  The laser rod can also be hollow to allow for pumping of the photons from either outside or inside the hollow bore or both.  Similarly, this hollow bore in the laser rod could also allow cooling fluids to be circulated therethrough.

Abstract: Two kinds of molten steel are poured into a mold for continuous casting.  A DC magnetic flux directed to intersect the thickness of poured contents (corresponding to the thickness of a slab) is provided when the mold is positioned at a predeter-mined height.  Molten steel is fed at positions above and below a static magnetic zone as a boundary which is formed by said DC magnetic flux and divides an inner space of the mold into top and bottom ones along the vertical direction, that is, the casting direction.  Where the difference (.DELTA.p) between the density p1 of molten steel to be fed above the static magnetic zone for form-ing the outer layer of a slab and the density p2 of molten steel to be fed below said zone for the inner layer is .DELTA.p = p1 - p2, the DC magnetic flux density (tesla) is adapted to satisfy the relations expressed by the following formulas: a) when .DELTA.p < 0, B > [2.83 x (.DELTA.p)2 + 1.68 x .DELTA.p + 0.30]; b) when 0 < .DELTA.p, B > [20.0 x (.DELTA.p)2 + 3.0 x .DELTA.p + 0.30].
