Title: Pressure frame designed in particular for an aircraft
Inventor: FILSEGGER HERMANN
IPC: B64C1/10
Filed: 1998-11-03
Abstract: The invention concerns a pressure frame designed in particular for an aircraft and consisting of a cover made of a composite material reinforced with glass fibres, preferably in one single piece, and reinforcement devices connected to the cover or produced integral therewith. The invention aims at providing a pressure frame as light and as inexpensive as possible while observing the load specifications in particular for heavy aircraft, and which is characterised by the reduction of risks of the cover being lifted towards the aircraft flight compartment. The invention is characterised in that the cover (4) has a substantially uniform thickness and at least one reinforcement device of the cover (4) is set in the centre and on the concave side of the cover.  Said cover (4) reinforcement device located in the central zone is advantageously formed by a reinforcing structure (7) oriented towards the cover (4) curve, for example a tapered structure, bowl-shaped or parabolic. A cavity is arranged between the cover (4) and the reinforcing structure (7).

IPC: C01F7/162
Filed: 1999-02-25
Abstract: A process for recovering one of alumina hydrate, magnesium hydroxide and magnesium aluminate spinel (MgAl2O4) from aluminum dross wherein the dross is processed to a non-metallic product (NMP). The dross may contain fluxing salts which are removed in providing the NMP. The NMP may be derived from aluminum dross which does not contain fluxing salts sometimes referred to as white dross. The process comprises digesting the non-metallic product with an acid selected from the group consisting of sulfuric, hydrochloric, hydrofluoric and phosphoric acid or mixtures thereof to provide a slurry containing dissolved alumina, magnesia and a solid component, for example, containing magnesium aluminate spinel. Instead of an acid, a base such as sodium hydroxide may be used. The slurry is filtered to separate the solid component from the liquid containing dissolved constituents such as alumina and magnesia to recover the solid component.

Title: Lats knock-out animal models and their uses
Inventor: TURENCHALK GREGORY S
IPC: A61K38/00
Filed: 1999-08-18
Abstract: A recombinant non-human animal having an inactivated lats gene is described. A lats knock-out mouse is exemplified. Because mice disrupted for the lats gene develop a variety of tumors, are susceptible to induction of skin tumors by exposure to carcinogens, and exhibit pituitary dysfunction, they have utility in screening for compounds effective to treat or prevent cancer or pituitary disorders. Compounds can be screened for activity in treating or preventing skin cancer in recombinant non-human animals which have an inactivated and in which skin tumors have been induced by exposure to carcinogens. Methods for treatment of cancers refractory to treatment with chemotherapy or radiation therapy by using a therapeutic that promotes lats function are also described. Additional methods are described for the treatment or prevention of diseases and disorders associated with aberrant levels of cdc2 activity with a therapeutic that either promotes, inhibits or antagonizes lats function.

Patent CA-2343910-A1 (CA)
Title: Improved ball valve
Inventor: COWIE GAVIN DAVID
IPC: F16K5/06
Filed: 1999-09-15
Abstract: A ball valve (10) is described which has a ball valve retaining mechanism which, when subject to very slight movement, allows a ball element (20) to be unloaded off a valve seat (48) during rotation, but remain in contact with the valve seat (48) so as to prevent debris ingress between the ball and the valve seat, and to instantaneously reload onto the valve seat upon the event of closure. This instantaneous and automatic redirection of the reaction load path at the occurrence of closure provides an effective seal against high pressure aggressive fluids to prevent fluid escaping beyond the valve components whilst, at the same time, allowing effective rotational movement of the valve to occur without providing rotational reliability. This solution allows conflicting load paths through the valve to be resolved, namely through the trunnion during rotation and through the valve seat during sealing.

Title: Game method using bets, variants and device for realising the same
Inventor: SILAEV ALEXANDR I
IPC: G06F19/00
Filed: 1998-11-17
Abstract: The present invention relates to methods and systems for playing games and lottery that involve making bets on information elements from a predetermined game set. This invention essentially involves creating a game set comprising N1 information elements by creating a set of N non-repetitive information codes in a computer memory and by distributing among the players using communication channels a plurality of signals containing information about the elements of the game set. Each participant makes a bet by selecting one of the elements in the game set. Feedback communication channels are used for transmitting signals for identifying the players and containing information about the bets. The method further involves generating data on the payment of the bets and on the drawing process thereof during the various rounds. The signals comprising information on the bets are recorded in a sequence which remains secret to the players until the round is over and which is used for transmitting them through the feedback communication channels. The drawing of the bets is made according to an iteration analytical method which remains secret to the players until the round is over and which is used for performing a quantitative distribution of the bets according to the elements of the game set. Each iteration is correlated with a sequential signal from the sequence of recorded signals comprising the information code of an element in the game set which is selected by a player as a bet. The method further involves determining the quantity of signals correlated with the information code of each element in the game set during a given round, and checking the observation of the bet drawing conditions. If these conditions are respected, the bets can then be drawn.

Title: Magnetic switching of charge separation lifetimes in artificial photosynthetic reaction centers
Inventor: MOORE THOMAS A
IPC: H01L29/82
Filed: 1999-10-01
Abstract: Excitation of a triad artificial photosynthetic reaction center consisting o f a porphyrin (P) convalently linked to a fullerene electron acceptor (C60) an d a carotenoid secondary donor (C) leads to the formation of a long-lived C.+- P- C60.- charge-separated state via photoinduced electron transfer. This reacti on occurs in a frozen organic glass down to at least 8 K. At 77 K, charge recombination of C.+-P-C60.- occurs on the .mu.s time scale, and yields sole ly the carotenoid triplet state. In the presence of a small (20mT) static magnetic field, the lifetime of the charge-separated state is increased by 5 0 %. This is ascribed to the effect of the magnetic field on interconversion o f the singlet and triplet biradicals. At zero field, the initially formed singlet biradical state is in equilibrium with the three triplet biradical sublevels, and all four states have comparable populations. Decay to the carotenoid triplet only occurs from the three triplet sublevels. In the presence of the field, the S and T0 states are still rapidly interconverting , but the T+ and T- states are isolated from the other two due to the electron ic Zeeman interaction, and are not significantly populated. Under these conditions, recombination to the triplet occurs only from T0, and the lifeti me of the charge-separatedstate increases. This effect can be used as the basis  for a magnetically controlled optical or optoelectronic switch (e.g. AND gat e).
